His actions in Season 12 make him the final antagonist of the series. He is also The Main Protagonist of The Attack on Titan Manga, and Anime. In the year 845 he witnessed the Titans break into his home, and devour his Mother. Afterwards he vowed to kill every single last Titan in existences. He is the current holder of both the Attack Titan, and the Founding Titan.

## Appearance

### Human Form

Eren is a young man of average height and muscular build. His facial features strongly resemble his mother's; he has a reasonably long, rounded face and sizable, expressive, teal-green eyes. His hair is short and black, and his bangs fall in a natural, middle-parted, curtain-type style. After his training and during his time as a soldier, he became very physically fit and muscular, although this is often unseen due to his relatively baggy clothing.[39] After the four-year time skip, Eren grew his hair down to his neck.

Eren is first seen wearing typical townsfolk attire that consists of brown trousers, a green shirt with string tassels at the collar, a reddish-brown coat, and simple brown shoes. A few years before the fall of Wall Maria, he also wore a red scarf, which he gave to Mikasa Ackerman the day they met. As a teenager, he is often seen in the typical Survey Corps uniform while training. His casual attire consists of a long beige shirt identical to the one he wore in his first appearance, a maroon sash around his waist, white trousers, and brown knee-high boots. He always keeps the key given to him by his father dangling around his neck on a string.

By the year 854, Eren has grown visibly taller, and his hair has grown down to shoulder length. He has a slight mustache and goatee, as well as bandages that cover his forehead and left eye.

Later Eren discards his Survey Corps attire and begins wearing a white shirt with dark pants underneath a simple black jacket.[42] He ties his hair back into a bun and shaves off his mustache and goatee.

### Attack Titan Form

As a Titan, Eren's appearance changes quite drastically. Along with a massive increase in height (to 15 m), his hair grows long enough to graze his shoulders, with his tongue and ears becoming elongated. His facial features also undergo a transformation. Along with a prominent, hooked nose, his eyes are deeply sunken within their sockets, and his mouth takes on an unusual, jagged shape that is unsuited for intelligible speech, though he is capable of howling and roaring when expressing his exhaustion and anger. He also lacks lips and flesh on his cheeks, exposing all his teeth. A third transparent eyelid can also be seen on both of his eyes.

Similar to other intelligent Titans, Eren's Titan form is well-proportioned and physically fit, sporting a well-defined, lean, muscular appearance in lieu of the more common pot-bellied or emaciated appearance of regular Titans.

In its burning state seen when it lifted the boulder in Trost and when it fought the Female Titan, the Titan was deep black, had burning marks all over his Titan, and had sharp teeth instead of straight teeth.

### Founding Titan Form

Eren's Founding Titan is drastically different than Ymir Fritz's Founding Titan, or any other Titan for that matter. Initially, much of the Titan is shrouded by the steam from the Wall Titans, but its sheer size is immediately noted, towering over the horde of Wall Titans. What appears to be the torso is devoid of flesh, resembling an enormous ribcage. The knobs of the backbone and ribs are grossly lengthened; the ribs reaching the ground while the arch of the spine extends far into the sky. The pelvis and legs are greatly undersized however, seemingly useless. Despite this, they are still taller than any Wall Titan. [45]

The upper body seems proportional with the legs, meaning that they are dwarfed by the "ribcage" (although it is revealed that the "ribcage" arose from the lower back). The head is the only part of the body with much flesh, although it is significantly deformed: both the ears and hair are greatly elongated; the cheeks are missing, exposing the molars; and the bottom jaw is nearly bare, only the lips and chin being present. Like a puppet, the upper body is suspended by sinew, supported by the vertebral knobs like a suspension bridge. Inside the Titan, Eren's head is disconnected from his torso; having been decapitated and rejoined by Ymir's power, it is connected by additional vertebrae to what presumably is his body. Some sinew supports his scalp.

The Titan walks with its "ribcage", undulating the ribs like a millipede's legs. It is fast enough to keep within view of the Rumbling.

### Pure Titan Form

Eren's Pure Titan form was much shorter than his current Titan form. It had short, rugged hair and a jagged, lipless mouth that exposed his teeth. The Pure Titan form also had a stocky build, a big head, and elongated ears.

## Personality

Eren is best described as hardheaded, strong-willed, passionate, and impulsive, which are attributes of his strong determination to protect mankind and eventually escape the Walls. As a young child, he was so intent on joining the Scout Regiment that he argued with and shouted at his mother, referring to the people in the village as "silly" and compared them to complacent livestock.[19]

As a child, Eren cared deeply for Armin, his best and only friend before he met his adoptive sister, Mikasa, and most importantly, his family, risking harm and even death in order to help them. This quality was most often demonstrated in the form of Eren taking on the larger boys who would bully Armin without hesitation; more tragically when he desperately attempted to lift the rubble crushing his mother during the Titans' assault in Shiganshina.[19] In contrast, Eren is also capable of displaying very violent behavior in the defense of people he does not even know. This is highlighted when he brutally slaughtered two of the human traffickers who captured Mikasa in order to rescue her, despite the fact that they were total strangers at the time.[22] Since witnessing his mother's gruesome demise and losing contact with his father, his fierce protectiveness to those he has left has only intensified.

Eren has a number of defining traits that date back to his childhood. He came to share Armin's awe of the lands beyond the Walls after the latter showed him a book depicting the wonders of the outside world, and decided to see it all for himself.[1] This led him to develop a scornful attitude to anyone content to live and die within the confines of the Walls without ever setting foot outside. This very contempt may have been the reason he did not easily make friends with his peers. He resented both the Walls that "caged" them in like cattle and the Titans that had driven humanity to erect them in the first place. As a result of this, he greatly admired the soldiers of the Scout Regiment, regarding them as "heroes," and wishing to join their ranks as soon as he became eligible for enrollment. He easily took offense when anyone spoke badly of the Scout Regiment, and his determination to join their ranks caused friction between himself and his mother, as well as to Mikasa.[19]

Eren had a marked lack of self-restraint that often led him into trouble, causing both his friends and family to worry about him. His limited self-control extended to his temper, and as a result, it was short at best and murderous at the very worst. When sufficiently provoked, his anger could drive him into a frenzy, accompanied by horrific levels of violence. Like many children, he tended to view the world in terms of black-and-white, having great compassion for humanity and its plight, but deeming those individuals who deny others their freedom as worthless scum unfit to be left alive. He also had the habit of thinking with his heart rather than his head, even in situations where his own life was in danger.[19]

These characteristic qualities have become more highly pronounced since his mother's death. He now focuses his destructive rage on the Titans, holding a virulent hatred for them, with the goal to rid the world of Titans one day.[21] Fueled by vengeance, he vowed to personally wipe every single one of them out and restore mankind to its rightful place. Though he feels great remorse for quarreling with his mother till the very end, he still continues to go against her wishes by seeking entry to the Scout Regiment. So strong is his desire to exterminate the Titans, he was plunged into despair when it seemed he could not even master the basics of the omni-directional mobility gear during training when his failure was in fact due to faulty equipment.[23] He is unafraid to voice his intentions of leaving the Walls to eliminate the Titans and is so consumed by his hatred that he seems not to fear them at all, earning him the nickname "suicidal bastard" from the other cadets.[24]

He possesses great amounts of selflessness, perseverance, fortitude, and a vigorous determination; managing to graduate fifth in his class despite his lack of natural talent.[25] He greatly appreciates and/or admires his comrades, and will swiftly fly into a rage if one of them is injured or killed in front of him. He prizes human life, but his personal sense of justice dictates that anyone who steals away the freedom and dreams of others deserves to die. Though his ordeals since the struggle for Trost have taught him restraint, Eren still tends to behave quite rashly and speaks his mind even when he knows he should not.[26] This has put him in grave danger on numerous occasions, and he often finds himself having to be rescued.

Eren, however, tends to lose confidence in himself when confronted with how he could do little to nothing in situations. This includes when Eren put his trust in the Special Operations Squad when he could have fought the Female Titan himself, resulting in the deaths of all of his squadmates save Levi.[27]

Eren's ordeals since the coup d'état have mellowed his personality considerably. When he discovered the truth about his father the night Wall Maria fell, he was willing to ask Historia Reiss to eat him for the good of humanity. He admitted that he viewed himself as weak, and that his reliance on the Attack Titan proved it. It took a lot of encouragement from his friends for him to overcome this state of despair and regain his passion.

By the time he finds out from his father's books that Titans are actually humans who were forced to transform by the Marleyan Government, he seems to have let go of his hatred against them.

Whilst assuming his Titan form, Eren seems to become more savage, bloodthirsty, and all-around uncontrollable. Though he is able to consciously control his Titan body after the struggle for Trost, he can very easily become caught up in the pleasure of slaughtering his enemies, indulging in thoughts so brutal he gives the impression of being insane.[27]

## History

Eren was born in Shiganshina District in the southern region of Wall Maria to Carla Jaeger and Grisha Jaeger. He had a few friends, though his best friend was Armin Arlelt, who he often defended from the neighborhood bullies. Armin inspired his passion to leave the Walls and travel by showing him a hidden book about the outside world.[1] He dreamed of joining the Scout Regiment as soon as he reached the enlistment age, in order to see the outside world. Because of this dream, Eren and Armin were regarded as heretics and harassed.[19]

When Eren was nine years old, he saved Mikasa Ackermann from being sold into slavery by bandits. On a visit to the Ackermanns' home, he and his father discovered both parents murdered and their daughter missing. Fearing the worst, Dr. Jaeger instructed Eren to wait at the foot of the mountain while he got the Military Police Regiment to conduct a search. However, Eren, wanting to rescue the missing girl as soon as possible, managed to track the bandits' trail to a small cabin in the forest behind the house.

Opening the door to the room where Mikasa was being held captive, he found her laying on the floor with two of the bandits keeping watch. Feigning distress and saying that he was lost, Eren got them to drop their guard.

As one of them closed in to pat his head, Eren slit his throat with a knife he had hidden behind his back and quickly ducked back out of the room. As the second man went after him with an axe, Eren charged at him with a makeshift spear, piercing him in the shoulder. Once he was down, Eren proceeded to stab him to death in a wild frenzy while Mikasa looked on in horror. As Eren untied her in the aftermath, he was caught off-guard by the third bandit, who proceeded to strangle him. Mikasa picked up the knife Eren used but balked at the thought of using it to kill someone. Eren urged her to fight back, warning her that they would both be killed if she did nothing. As Eren began to lose consciousness, Mikasa finally lost all inhibition and lunged at their attacker, stabbing him through the heart and killing him instantly.

When Dr. Jaeger eventually returned with the police in tow, he took Eren aside scolded him angrily for his reckless behavior. While Eren was genuinely sorry for upsetting his father, he expressed no remorse whatsoever for killing the bandits. When Mikasa remarked that she was cold, Eren gave her the scarf from his own neck; and when Dr. Jaeger invited Mikasa to live with their family from then on, Eren accepted her with no hesitation, tugging on her sleeve and shyly insisting that they return home.

## Story

### The Fall of Shiganshina arc

After waking up from a nightmare interrupted by Mikasa, they stroll through the city and Eren expresses anger at being kept like cattle within the Walls, revealing his intentions in joining the Scout Regiment. Mikasa scolds him, not taking his words seriously, and later reveals what he said to their parents.

Carla is shocked and angered, saying she will not let him join the Scouts due to their high mortality rate. She begs Grisha to talk some sense into Eren, but Grisha ignores her objections and instead announces that he will be leaving for a few days on a trip and that when he comes back, he will show Eren what he has hidden in the basement of their home. Enthralled, Eren joins his mother and Mikasa in waving him off. Carla reminds him that she will not allow him to join the Scout Regiment, and they exchange a heated argument before he runs off.

Eren and Mikasa scare off bullies harassing their neighborhood friend Armin Arlelt. Eren offers Armin a hand but Armin rejects, expressing discontent with his abilities to protect himself and admits he is weak. The three stroll through Shiganshina and settle by the riverbank, where Eren reveals his intentions of joining the Scout Regiment to Armin.

Suddenly, lightning strikes, and an earthquake breaks out. The three gather in the center of the district with other civilians, where they all gawk in horror at the sight of a Titan larger than Wall Maria. The Titan kicks a hole through Wall Maria's gate, sending massive pieces of debris throughout the town.

Eren and Mikasa hurry home as Titans begin entering the district, arriving to find find their house crushed by a large rock and his mother trapped beneath the rubble. She says that the rubble crushed her legs and she can not move, but Eren insists that he will carry her to safety. As they argue, a Titan begins approaching the collapsed house. A Garrison member, Hannes, arrives and Carla begs that he takes the kids and run. Hannes rushes to kill the Titan and save Carla, but quickly changes his mind and takes Eren and Mikasa away. As Hannes carries the two on his shoulders and retreats, Eren witnesses as the Titan eats his mother.[19]

As the evacuation of Shiganshina is underway, Eren, Mikasa, and Hannes arrive in an alley and Eren starts attacking Hannes with leaving his mother. Hannes says that the reason Eren could not save her was that even though he had the courage, he lacked the strength, and Hannes himself lacked the courage even though he had the strength.

Hannes leaves Eren and Mikasa on the boat leaving the Titan-infested city. There, Eren and Mikasa witness an Armored Titan destroy the back gate of Shiganshina. Eren, Armin, and Mikasa are forced to depart on the boat as Eren realizes that he can never return home, and vows to kill every Titan in existence.[21]

After the fall of Wall Maria, Grisha finds Eren and takes him into a nearby forest. Grisha instructs Eren to retake Wall Maria and gives him the key to the basement,[21] before giving him a Titan injection that turns him into a Pure Titan. Eren instinctively eats his father, granting him the Power of the Titans.

### Humanity's Comeback arc.

After the fall of Wall Maria, Eren, Mikasa, and Armin briefly stay in a landfill working on a farm before reaching the proper age to enroll in the military.

After these two years, they begin their first day on the training grounds in the 104th Cadet Corps as commandant Keith Sadies grills the fresh recruits as part of their "Rite of Passage." Eren restores his vow to kill all Titans, and that next time around, they will be the ones who will be devoured.[21]

Before training, Eren draws a crowd of cadets at dinnertime, describing the fall of Wall Maria to them. He becomes sick as he remembers his mother being eaten, but continues his story, attributing it to eagerness to begin his training and kill all the Titans with the Scout Regiment. Jean Kirschtein interrupts Eren and mocks his decision, nearly leading to a fight between them. The bell signaling the end of dinner rings breaking the tension and the two drop their disagreement with each other.

The next day, the cadets begin practicing with omni-directional mobility gear, with their first task to balance themselves on their belts. Unlike the other recruits, Eren utterly fails to keep himself upright and takes extra tutoring from Armin and Mikasa. He knocks himself out and at dinner, other cadets mock his performance especially after his pledge to kill all Titans.

Back at the dorm, Conny and Jean do not offer any suggestions and Eren visits Reiner Braun and Bertholdt Hoover for help. Although they are reluctant at first, the group exchange their stories of how they first encountered the Titans. The three exchange tips and later, depart as friends.

Later, Eren is back at the practice rigging as Sadies lets him try to balance himself on ODM gear one last time before he will be shipped to the landfills. At first, it appears Eren can maintain his balance and his peers begin cheering, but just as quickly, Eren flips upside down. Sadies has him put back on the ground and after a few moments of contemplation has Eren switch equipment with Thomas Wagner. Eren easily keeps his balance and Sadies reveals his equipment was defective, impressing everyone with his feat of keeping his balance, even for a while, with the broken equipment. Sadies mentally notes to Eren's father, Grisha Jaeger, that his son is finally becoming a soldier.[23]

In 850, the 104th Cadet Corps is undergoing a fitness assessment supervised by Commandant Sadies. The commandant notes that Eren's grades have improved with his unparalleled effort and that he possesses twice the sense of purpose than anyone else. Later, the cadets are practicing hand-to-hand combat as Eren disarms Reiner. As they switch roles, Eren remarks on the uselessness of learning anti-human combat as well as attacking an armed foe bare-handed, remembering the day he killed the bandits in.

Reiner spots Annie Leonhart avoiding practice and to show her up, has her try to disarm Eren. When Eren lunges at her, she swiftly kicks his foot out from under him and drops him on his head with a few moves. Eren praises her technique, but Annie believes this training is pointless as it is not a factor in their rankings. She points out the hypocrisy of having the top 10 graduates, the most effective Titan fighters, be the only ones eligible to join the Military Police and live in the safest human territory.

Later that night as the cadets are eating dinner, Eren hears Jean's discussion with Marco on the efficient use of gas in the omni-directional gear and how such an advanced technique would allow him to be ranked higher and join the Military Police. Eren insults Jean's shallow reasoning in wanting to join the Military Police and the two almost come to blows once more. Jean grabs Eren and tries to punch him, and Eren gets ready to retaliate, he notices both Reiner and Annie closely watching the situation; using Annie's disarmament technique, Eren quickly ends the fight to resolve the situation. When Jean insults him, Eren tells Jean he learned that combat technique while Jean was not taking training seriously and wonders how could he call himself a soldier if a carefree life is his idea of the real world.

The graduation of the cadets draws closer until Eren finally graduates in the top 10 of the 104th Cadet Corps. After graduation, he is assigned to clean the cannons atop Wall Rose with Sasha, Conny, and a few others. There they witness the return of the Colossus Titan, who has not been seen in the last five years.

### Distress

In the year 848, Eren and his fellow cadets embark on a navigation training exercise to learn how to sustain themselves in times of peace, during which he and Jean continually get at each other's throats.

During the night, the group is ambushed while they sleep. Held at gunpoint, they are unable to do anything as the thieves carry off their ODM gear and Historia Reiss. Marco Bodt suggests abandoning the mission and getting help from Sadies, but Eren convinces the group to help him chase down the thieves before they can get away. Sasha suggests using a higher vantage point to look for the bandits, and the group is able to successfully locate where the thieves are camping for the night.

The group devises a plan to confront the bandits. After Conny and Sasha successfully block off the bandits' route out of the forest, Marco is able to determine which of their carriages they are carrying the cadets' stolen goods in, and alerts Eren and Jean so that they can attack. When Eren and Jean are able to recover the cadets' ODM gear, but not Historia, they use their gear to continue their pursuit. The group confronts the bandits again, but are left unable to fight when the men begin threatening Historia's life. Helpless, they are forced to hand over their gear again, only to be saved by the timely arrival of Thomas' group, who successfully ambush and capture the attackers.

Following the incident, Marco has a conversation with Eren, stating his belief that Jean would have made a much better choice to lead the mission, to which Eren vehemently disagrees.

### A Sudden Visitor: The Torturous Curse of Adolescence

In the year 849, Eren and Mikasa confusedly watch a brewing fight between Sasha and Jean. Afterward, he attempts to unload a crate from a wagon but was unable to due to its weight. Meanwhile, he looks over at Mikasa, who is carrying three without any trouble. She offers to help him with his, but he angrily refuses. Later in the dining hall, Eren advises Jean to be nicer to his mother.

### The Struggle for Trost arc

When the newly graduated recruits of the 104th are assigned to clean the cannons on top of Wall Rose, the Colossal Titan appears for the first time in five years. Eren faces the Titan alone, but despite getting close enough to the Titan to nearly slice the nape of its neck, it vanishes into thin air after kicking down Trost's outer gate and dismantling the cannons atop the Wall.

In response to the crisis, the new recruits are split into squads in charge of defending different parts of the city. Although Eren and his squad are initially confident, they are quickly sent into a panic when Thomas Wagner is devoured. Enraged, Eren leaps into battle after the Titan, only to have his leg bitten off below the knee. The rest of his group join the fight, but are also killed by Titans. Just as Armin is about to get eaten, Eren pulls his friend out of a Titan's mouth, switching places with him. Eren is swallowed, his left arm being severed as the Titan bites down on him.

In the stomach of the Titan, Eren comes across the dead or dying soldiers who were devoured by the Titan. As he remembers his goal to kill every last Titan alive, his anguish triggers his first transformation into his Attack Titan form. Bursting out of the Titan that devoured him, proceeds to wreak havoc on all the Titans he finds.

In the process, he unknowingly saves Mikasa’s life from another Titan and is baited by Armin, Conny, and Mikasa to help fend off a procession of Titans from a storage headquarters for the compressed gas used to power their ODM gear.

Eventually, Eren appears to run out of energy and begins to be overwhelmed by the Titans. The sight of the Titan that killed Thomas proves to be enough to drive Eren to throw off the Titans holding him down and kill the Titan by biting its nape off. As soon as the massacre is over, Eren falls to the ground and his human form emerges from the back of his Titan form’s neck, to the shock of all the onlookers. He is retrieved by an overwhelmed Mikasa.

When he regains consciousness, Eren finds himself cornered with Armin and Mikasa by a hostile military force under the command of Kitz Woermann. After witnessing him emerging from a Titan, they have concluded that he is an enemy of humanity and intend to kill him. They fire a cannon at the three of them and Eren instinctively grabs onto his two friends and bites his own hand, partially transforming into a Titan and blocking the cannonball with the Titan's hand.[30] While the cannon is being reloaded, Eren asks Armin to try and talk them out of the situation. This is met with limited success until Commander Dot Pyxis intervenes and orders Woermann to stand down.

A plan is made for Eren to use his Titan form to move a huge boulder near the gate which they had placed to reseal Trost's gate in the event of a Titan incursion but had been unable to move with their limited resources in the aftermath of the Titan assault. Eren is assigned to a team which will defend him while he carries the boulder. Upon his transformation, however, he attacks Mikasa. Eren ends up wounding himself and his body fails to regenerate, and the mission is declared a failure. Despite this, Ian Dietrich, the leader of the group, decides they must stay and guard Eren.

Armin arrives on the scene and convinces Mikasa to go help fend off the Titans while he tries to get through to Eren by stabbing his human form through his Titan's nape. Eventually, he is able to do so, reminding Eren that they wanted to see the world together, which causes Eren to remember his desire to wipe out the Titans. Eren carries the boulder and is able to plug the hole in the Wall. Before they can bring Eren to safety, however, Eren and his group are attacked from behind by two Titans. They are saved by the timely arrival of Captain Levi, who has arrived ahead of the returning Scout Regiment.

### Eve of the Counterattack arc

After the events of Trost, Eren is placed in the custody of the Military Police and kept chained in a dungeon prison cell in the Royal Capital beneath a courtroom. While he is there, he is paid a visit by Commander Erwin Smith and Captain Levi. Upon hearing his motive to kill Titans, Levi says he will accept him into the Scout Regiment. Eren is left there for some time before being escorted by Scout Regiment members to the courtroom where he was tried, with Premier Dhalis Zachary preceding over events.

During his trial, the Military Police and Order of the Walls call for his dissection and execution while the Scout Regiment, argues in favor of using his power to their advantage in scouting missions. After an outburst by Eren, Levi savagely beats him to prove that Eren will not pose a threat to him. It is decided his fate will be decided after a “test” mission with the Scout Regiment. Afterward, Erwin thanks him for his cooperation.

After joining the Scout Regiment, Eren is assigned to Levi's Special Operations Squad and sent to an abandoned castle which had formerly served as the base of operations for the Scout Regiment. While there, he is tasked with cleaning duty by Levi while also helping Squad Leader Hange Zoë with her Titan experiments.

During one of the experiments with his Titan abilities, Eren is lowered into a well before being told to transform into a Titan, in case he loses control. However, Eren is unable to activate his Titan abilities. He is eventually brought back to the surface and have his wounds tended to by Levi's squad, who express their relief at his inability to turn into a Titan. However, whilst bending over to pick up a dropped spoon with his injured hand, Eren accidentally triggers his Titan ability in a partial transformation, creating a Titan hand in a small explosion.

Levi's squad surrounds Eren, demanding that he prove he is not a threat to them, and the situation has to be defused by Levi and Hange. After the incident, with the help of Hange's deductions, Eren learns that a Titan transformation requires him to have a clear goal in mind in addition to self-injury.

While he is with Levi's squad, Eren meets some of his classmates from the 104th Cadet Corps who have opted to join the Scout Regiment. Eren is surprised to see Jean among them and is given a lecture by Jean about his responsibilities to humanity.

### The 57th Exterior Scouting Mission arc

After a month of training, Eren and the Scout Regiment embark on the 57th Exterior Scouting Mission. After leaving the safety of the Walls, the Scouts assume the Long-Distance Enemy Scouting Formation with Eren positioned at the center of the formation, where it is the safest.[24]

It soon becomes apparent to Eren that something is going wrong with the expedition as his squad receives the news of the decimation of the right wing of the formation and notice black flares, despite the fact that they are in the safest position in the formation. Soon after, the Scouts head toward a Forest of Giant Trees. The central column of the scouting force, including Eren and Levi's squad, are told to enter the forest, while the rest of the soldiers were to stand guard at the perimeter of the forest to prevent any Titans from entering.

Soon after entering the forest, Squad Levi is set upon by a seemingly intelligent Female Titan, who is able to dispatch pursuing soldiers with ease. Seeing the soldiers perish one by one, Eren is tempted to use his Titan power to fight the Female Titan. Levi allows this choice, but recalling Levi and his squad's trust in him when he accidentally used his Titan powers, Eren decides to trust in his team instead.[32]

As the Female Titan is inches from grabbing Eren,it is ambushed by a trap set by the Scouts. Eren and the rest of his team excluding Levi ride out of the forest firm in the belief that the Titan was captured and her human self apprehended. This is proved false as the unidentifiable human form of the Female Titan kills Gunther before re-transforming into a Titan. The remaining three team members tell Eren to go on while they attack the Female Titan. Eren expressed his desire to stay and fight with them, but again, is convinced otherwise and begins to retreat. Although the three soldiers manage to blind the Female Titan and cripple her arms, they were caught off guard when the Female Titan regenerates an eye much faster than they had expected, resulting in their deaths. Upon seeing this, Eren, filled with regret, finally transforms into a Titan and engages the Female Titan.

Even though he initially had the upper hand against the crippled Female Titan, Eren quickly spends all of his energy and ultimately loses the fight. Mikasa pursues the Female Titan as it flees with Eren and is able to save him with Levi's help.

The Scout Regiment returns to Wall Rose in defeat, with the failure of the mission to capture the Female Titan and the loss of the lives of many soldiers. Due to the mission's failure, Eren is ordered to be handed over to the Military in Wall Sina.

### Assault on Stohess arc

Before Eren can be handed over to the Military, he is let in on a plan by Commander Erwin to capture the Female Titan, whom Armin has deduced to be Annie Leonhart. Eren is initially shocked and angry at the accusation, refusing to believe that such a betrayal by one of his fellow cadets is possible. However, after Mikasa tells him to think back to when he was fighting against the Female Titan in the forest, he realizes that the fighting style the Female Titan exhibited was exactly the same as Annie's, forcing him to come to terms with Annie's betrayal. He agrees to participate in the plan to capture her.

After Armin convinces Annie to join them in escorting Eren out of the city, they lead her to the entrance to an underground tunnel, where she refuses to continue following them. Despite Eren's continued pleas for her to join them and prove her innocence, Annie transforms and he, Mikasa, and Armin are forced into the underground tunnel to escape from her Titan. As per the plan, Eren tries to transform but can not because of his disbelief at Annie's betrayal. As the Scout Regiment tries in vain to capture the Female Titan, Eren is reminded of the lives Annie took as the Female Titan as well as his vow to exterminate the Titans, allowing him to finally overcome his inhibitions, transform into his Titan form, and engage the Female Titan for the second time.

Even though Eren is in better control of his Titan and is equipped with knowledge of his opponent this time round, he is ultimately no match for Annie's superior fighting technique and hardening ability. He manages to throw Annie into some buildings, but gets his right leg taken off by a hardened kick from Annie, who proceeds to slam him into a building and pummel his head repeatedly with her hardened fist.

Unexpectedly, Annie stops her assault on Eren and flees toward the wall, giving him the opportunity to drive himself into a rage, chasing after the Female Titan. She is able to kick him aside and attempt to climb up the Wall with her hardened fingers, but Eren grabs hold of one of her legs. He is kicked off by Annie, but Mikasa slices her Titan's fingers off, causing her to fall back to the ground where Eren can restrain her. He tears her head off and bites her nape clean off of her body, exposing Annie's human form inside. However, upon seeing Annie crying, Eren stops himself. This gives Annie a chance to use her hardening ability, encasing herself in a crystal, which causes her Titan body to start merging with Eren as well. Eren is saved by Levi, who cuts him out of his Titan before he can be encased.

Some time later, Eren wakes up in his bed, having recovered from his injuries. He is aware of Annie being frozen, with Jean confirming that they got nothing from the operation. Unexpectedly, Armin states that Eren is the one who let that happen. After a short hesitation, Eren confirms that upon seeing Annie, he could not move. After Armin and Jean leave, Eren confides to Mikasa about his feelings during the battle. Mikasa expresses herself to be happy that he returned alive.

### Clash of the Titans arc

When Wall Rose is supposedly breached, Eren makes his way to Utgard Castle under squad leader Hange to save his comrades stranded there. Eren and the rest of the Scouts arrive just in time to save their comrades, excluding the members of squad Miche who had already died. When they arrive Eren kills a 7 meter Titan and celebrates his first kill as a Scout in human form, before tripping and being scolded for endangering himself. He then goes on to meet with his fellow recruits.

In the aftermath, Eren is among the soldiers on top of the Wall recovering from the ordeal at Utgard. Eren asks about Reiner's condition due to his injured arm and listens to him talk about the times he has nearly died. Bertholdt then reassures Reiner that they do not have much left to do and can return home soon. Hannes then arrives with news that the Wall has not been breached, prompting Hange to order them to move to Trost District. Reiner then asks to speak with Eren and reveals that five years ago, he and Bertholdt breached the Wall and are the true identities of the Armored and Colossal Titans, going on to say that their objective was to wipe out all the humans living in the Walls, but that if Eren comes with them to their hometown they will not attack the Wall again. Eren briefly remembers a discussion the previous night with Hange, who discussed Reiner and Bertholdt potentially being accomplices to Annie. Armin slowly puts together that Reiner attempted to usher Eren's potential location out of him during the 57th exterior scouting mission, and then cut the information into Annie's palm when she grabbed him. Hange warns the three to act carefully around Reiner and Bertholdt, and tells them not to mention anything to do with Annie or their suspicions.

In the present, Eren tries to persuade Reiner to believe that he is tired and not thinking straight. Bertholdt plays along, and Eren says that even if the two are responsible for the mass murder of humankind, they could not expect him to go with them willingly. This surprises Reiner and he admits that he must have gone mad, but then claims that he has been surrounded by fools for too long. He then explains that he no longer knows what is right or wrong, but what he does know is that he must complete his mission. Reiner removes the bandage on his arm and reveals the rapidly healing wound, discharging steam. He moves in to take Eren by at that moment, Mikasa attacks them, chopping off Reiner's hand and through his arm while nearly decapitating Bertholdt. Reiner tackles Mikasa and prevents her from killing Bertholdt and then arises beside his friend, bloodied, and the two transform. This throws the soldiers back, with Reiner grabbing Eren and Bertholdt taking the injured Ymir. Eren reminisces about the times they spent together, then bites his hand to transform and fight.

After Eren gains the upper hand on Reiner, Reiner begins pushing himself and Eren along the Wall before Mikasa swings in and slices through Reiner's now vulnerable legs, weakening him. He suddenly opens his mouth and roars. When no Titans come, Armin wonders what the roar was for and looks up at the Colossal Titan.[38]

Atop the wall, Conny and the others also contemplate Reiner's roar. As Conny looks at the Colossal Titan whose hands and face have withered to bone, he begins to shout. The Colossal Titan's ribs break and it falls over the wall, head first straight into Eren and Reiner.[38] The impact is so immense that some soldiers are flung over the Wall. Armin attempts looks for Eren in the dust of the impact before suddenly spotting the Armored Titan running away with Bertholdt and an unconscious Eren.

Later the same day, Eren wakes up again to find he is missing both his arms.[39] He then sees Reiner and Bertholdt back in human form as well as Ymir who has lost her leg and arm. After questioning Reiner and Bertholdt as well as Ymir, Eren begins to shout at them calling them 'murderers' and says that he will find the most painful and horrid way for them to die. In the distance, however, Reiner and Bertholdt spot the distinct green and red flares of the Scout Regiment approaching them.[40]

After contemplating when they are going to leave, Eren questions Ymir about who the real enemy to which she replies "Who knows?"[40] Reiner then states that they must immediately leave and warns Eren not to resist. Eren, telling Reiner that there is no way he can resist, stands back and runs at Reiner, pushing him over and repeatedly hitting him in the face with one of his stumps. While Bertholdt and Ymir talk, Eren is overpowered by Reiner and is eventually knocked out.

After Ymir transforms into a Titan and retrieves Historia, she escapes and jumps onto Reiner who has now transformed into his own Titan form. The two run away along with Bertholdt and an unconscious Eren strapped to him.

After Erwin notices the Armored Titan running away, he orders the soldiers to pursue him, and let any Titans follow them. The Armored Titan uses his hands to protect Bertholdt and stop Eren from being retrieved by Mikasa. After Connie, Jean and Sasha try persuading Bertholdt to give up, Hannes warns them of a large group of Titans advancing straight towards them, being led by Erwin and a large force of soldiers.

The Armored Titan is quickly overwhelmed by them and Eren shortly wakes up. He begins pushing Bertholdt against Reiner's hand in a futile attempt to escape. In an attempt to free himself, the Armored Titan removes his hands, exposing both Eren and Bertholdt so he can punch his way out of the pile of Titans. This gives Mikasa the opportunity to attack Bertholdt and try to free Eren. As she rushes forward, Bertholdt dodges and Eren tries to warn Mikasa of a Titan behind her. It squeezes her hard enough to crush her ribs, but Jean frees her before she can be eaten.

Armin lands on the Armored Titan and tells Bertholdt and Reiner that Annie is being tortured and the two of them are about to leave her behind. This is enough to distract Bertholdt so that he is unprepared for Erwin's approach.

Erwin grapples up with one arm and slashes at Bertholdt's chest, freeing Eren. Mikasa then grabs him before landing on their horses. As they flee, a large Titan is sent flying and creates a large explosion of dust. This causes some soldiers to fall off their horses including Eren and Mikasa. In the fog, they see the barely visible body of a very tall Titan slowing advancing toward them. Eren widens his eyes as he recognizes this is the exact same Titan that ate his mother.[42]

Hannes steps forward to protect Eren and Mikasa. While he distracts the Titan, Eren shouts for Mikasa to free him, believing that he is the only one who can stop this now. But when he tries to transform into a Titan, nothing happens because he is still recovering from his injuries.

He is devastated when Hannes gets eaten, finding himself just as powerless now as he had been when his mother died. Mikasa reassures him about the value of his life and how much he has meant to her. This fills Eren with rage and sadness. He stands up and punches the Smiling Titan in the hand as it reaches for him. Eren screams and another Titan attacks the Smiling Titan. Elsewhere around them, the Titans that were fighting the Scouts turn and start running to the Smiling Titan, surrounding and devouring it.

Eren takes advantage of the situation and flees, carrying Mikasa on his back. When Reiner and Bertholdt pursue him, he screams again, and the Titans turn to attack them. Eren escapes with the rest of the surviving soldiers and they return to Trost District, where he learns that the Scout Regiment lost more than half its veteran soldiers in rescuing him. No casualties were incurred on the way back, and Armin and Jean theorize that it is because Eren was somehow able to control them. Eren resolves to learn how to control the Titans, seal Wall Maria, and make Reiner pay as a way to atone for all the lives lost.

### The Uprising Arc

Some time afterward, Eren and Historia are sent away with the new Squad Levi to be safeguarded in an isolated cabin in the forest. Eren frantically attempts to clean their hideout before Levi's arrival, scolding Jean for the lackluster cleaning on his part. When Levi arrives, he is dissatisfied with their cleaning, much to Eren's dismay. Holding off on that discussion for later, Levi takes his squad out to assist in Hange's experiments on Eren's Titan abilities.

Eren participates in Hange's experiments without much success. He fails to show any signs of hardening, and upon a later transformation collapses in a smaller, malformed Titan body. Hange and Mikasa remove Eren from his Titan, and notice his disfigured face from where he had began fusing to the body.[44]

After spending a whole day resting, Eren comes into the kitchen of the cabin and expresses disappointment that the plan to repair the Wall has been shelved because of him. Soon after, Historia tells him that it must be nice to have a goal in mind, even if it is difficult to achieve, where as she has no idea what she wants now that Ymir is gone. Eren is glad that Historia has started speaking again, but she apologizes that the good-girl Christa that everyone knew is gone. Eren admits that he never liked her previous self, finding it forced and unnatural. He prefers her now that she is a normal, honest girl. As he also remembers Ymir, a memory of her talking to Bertholdt comes back to him.[44]

After hearing of Pastor Nick's murder, Levi reads a message from Erwin and orders everybody out of the cabin. Outside, Levi reveals that the government is freezing all Scout Regiment activity outside the Walls and demanding custody of Eren and Historia. Before heading for Trost, Eren hands Hange a message detailing the conversation he had remembered between Ymir and Bertholdt.

Eren rides alongside Historia in an enclosed wagon driven by Keiji, while Levi runs a decoy strategy with Jean and Armin posing as the two.[44] The wagon is attacked by members of the Military Police, who manage to tear the roof from the wagon using their mobility gear. Eren picks up a musket to fire on the attackers, but is tranquilized alongside Historia. Despite an effort from Levi Squad to recover them, the two are ultimately kidnapped successfully.

Inside a house at nightfall, Rod Reiss reunites with his daughter, Historia, while a half-conscious Eren watches from the side.[45] Later in the night, Eren is transported in a horse drawn carriage to be taken into Reiss family territory.

Eren awakes in a large crystalline chapel, shortly after having a vision of a dark-haired girl brushing her hair in a mirror. Suddenly rousing, Eren realizes he is gagged and restrained by chains atop a raised platform. As he struggles to break free, he spots Historia approaching below him.[47] He is glad to see she is safe and Historia assures him that her father has been misunderstood, having only acted in ways that are beneficial for humanity. Eren finds the cavern they are in familiar and Rod suggests that he and Historia lay their hands on Eren's back to help him remember. When they do, it triggers memories of Rod and his family, another Titan, a member of the Scout Regiment, his father's key, and then himself about to be injected with a syringe. Eren realizes that he is seeing his father Grisha's memories and is stunned by the revelation he had eaten his father.[20]

Once the three of them are alone, Rod opens a satchel and reveals a syringe, which Eren recognizes as the same kind his father had used on him. As Rod explains his plan for Historia to take back the Founding Titan, Eren begins panicking and struggling against his restraints. Rod explains that the Founding Titan was used to construct the three Walls and alter humanity's memories, claiming that the Founding Titan would be able to rid the world of Titans. However, its powers can only be fully utilized by a member of the Reiss family. Kenny, overhearing Rod's words as he returns, is distraught to learn he will not be able to use Frieda's power if he devours Eren, and in his anger begins undoing Eren's restraints. Intending to force Eren and Historia to battle each other over possession of Frieda's power, Kenny cuts open Eren's forehead so that he will be able to transform, before retreating to a safe distance.

However, Eren refuses to transform. Heartbroken to learn that Frieda could have put an end to the Titans and prevented so many of the deaths that had occurred since the fall of Wall Maria, Eren begs Historia to eat him so that she can use the power that his father stole to save humanity. Moved by Eren's words, Historia incapacitates her father and begins freeing Eren from the restraints that still hold him, to Eren's shock and despair.

As Rod transforms himself into a Titan, Eren begs Historia to allow her father to eat him. Historia refuses, explaining that even if she is an enemy to humanity, she is still Eren's friend. She is blown back by the winds created from Rod's transformation, but Levi and his squad arrive in time to save her and get the keys to Eren's chains. The ceiling begins caving in due to the sheer size of Rod's Titan and the squad's escape is blocked. Eren realizes that everyone with him is going to die.

As the squad considers ways to escape, Eren apologizes for being useless and Levi tells him that he has a choice to make. Spurred by Levi's words, Eren grabs a bottle labeled "Armor" that had fallen out of Rod's satchel and bites into it. After transforming into a Titan, Eren is able to harden it and reinforce the structural integrity of the cavern around it.

The squad climbs out of the ruined cavern and regroups to chase after Rod, who has become an Abnormal Titan twice the size of the Colossus Titan. Hange discusses the limitations of the Reiss family's Founding Titan with Eren and Historia and how even if a descendant of the family receives it, they are controlled by the will of the First King. Eren still considers being eaten by Rod to save humanity, but Historia is against it. The Reiss family had already tried undoing the brainwashing and once Rod has the Founding Titan's power, he can alter everyone's memories so they have no interest in restraining him.

Historia argues that taking away the Reiss family's ability to alter memories was the only way to save humanity, prompting Eren to remember his father's words from right before he injected him. His father asked him to learn to control this power to save Mikasa, Armin, and everyone else. They meet up with Erwin and his forces, and the Scouts all proceed to Orvud District to intercept Rod's Titan.[49] While en route, Eren screams at Rod and punches the air in a vain attempt to activate the Founding Titan and control the giant Titan the same way he had controlled the other Pure Titans.

Eren helps the scouts stack barrels of gunpowder together on a net of rope. He watches Historia stand up to Erwin and admires how strong she has become compared to him. Feeling melancholy that humanity has to depend on someone like him, he spots children in Orvud who remind him of himself as a child and thinks back to when the Colossus Titan first appeared. Armin tells him that it will be different from before, because this time the soldiers on the Wall can fight back. Eren punches himself, to try beating out his feelings of uselessness.

When Rod's Titan arrives and pulls itself up to the Wall, Eren transforms into his Titan form. He takes the net stuffed with barrels and shoves it into the open mouth of the Titan, which is hot enough to make the gunpowder ignite. This causes the Titan's head and neck to explode and enables the scouts to attack the flying chunks of meat in hope of destroying the nape.[50]

After Historia is crowned as the new queen, Eren and Squad Levi accompany her as she goes to find Levi so she can punch him. Eren, terrified for his comrade, tries to talk her down, and begs Mikasa to tell Historia that she was only joking when she suggested hitting Levi. Historia refuses to back down and punches Levi, but Eren and his comrades are all surprised when Levi reacts by smiling and thanking them.

Two months after Historia becomes queen, Eren and the other members of the 104th volunteer at an orphanage that she has started. He is impressed by how much she has thought things through to aid the people she wants to help most. She catches Eren, Jean, and Armin slacking by the fence and goads them into carrying their share of boxes. Jean and Armin go on ahead and she talks to Eren about the progress with his hardening experiments.

Eren says they are going well, but they need to hurry before Reiner and Bertholdt come back. She asks what he would do if they meet up again, and Eren says he will have to kill them, not because he wants to, but because he has to. He tells Historia that she is amazing for having done all this despite her words about dooming humanity, which causes Mikasa to abruptly interrupt the conversation and take Eren's load away from him.

Thanks to Eren's hardening experiments, a Titan guillotine is developed, giving soldiers a reusable weapon to safely kill Titans without risking their lives. However, creating the materials for one puts a strain on Eren's body.

As Eren and his friends eat dinner in the mess hall, Conny leaves to go check on his village to see if he can learn anything new. This causes Eren to remember the events of the past few months, particularly those concerning Ymir and how she said her life was like a nightmare when she was a Titan outside of the Walls. He wonders if Titans are just humans tormented by nightmares and how there must have been a time when he was like that too, but all he remembers is what his father saw when Eren ate him.

Jean tells Eren what he really should focus on remembering is the identity of that Scout Regiment soldier from his father's memories. Eren agrees that man has to know something and after Jean jokes that what he needs is a headbutt from their commandant, Eren realizes that the man his father had seen was Commandant Keith Sadies.

The next morning Eren, Armin, Mikasa, Jean, Levi, Hange, and Sasha visit Keith. Keith invites them inside to speak, pointing out that Eren resembles his parents. Eren then asks him to tell them all that he knows. Keith starts telling what he knows, how he met Grisha and everything he knows about him. Keith finally confesses that he is nothing more than a bystander and that he has no power to change things.[10]

Time goes by, and the operation to retake Wall Maria is ready. The day before the operation, the soldiers have a great dinner in order to ready them for the operation. However, the food turns Sasha into a mindless state, and she has to be retrained by Eren and Connie. Her lash out causes the two to reminisce about how things have changed in three months since the battle of Trost. The night continues and Jean starts a fight against Eren by insulting him. While they brawl, they wonder why nobody is stopping them, when suddenly Levi comes and knocks them.

After the fight, Eren, Armin and Mikasa have a conversation about their future. They talk about how strong and weak people need to combine their abilities in order to succeed. After mistaking a Garrison soldier for Hannes, Mikasa wonders if they will be able to go back to easier times when they retake Wall Maria. Eren answers that if may not be possible, but that is the reason why they must make them pay. Armin also adds that there is more beyond the Walls and that it can be discovered thanks to being part of the Scout Regiment. Finally, he vows to see the ocean, without noticing that Levi is overhearing their conversation.

The next morning, the soldiers are ready to depart on their mission. They become very surprised when they see that the civilians are cheering them. Finally, Erwin orders the start of the operation and Eren travels towards Shiganshina along with Squad Levi.

Although he insists, when asked, that he is just shaking from the cold, Armin assures him that it is normal to feel scared of the Titans and reminds Eren of when he was nearly eaten during the Battle for Trost. Eren reveals that he sacrificed himself to save Armin that day because he had remembered the first time Armin told him about the outside world, which had caused him to realize just how much the Titans had taken from the humans.

Arriving in Shiganshina, the scouts quickly scale Wall Maria with their ODM gear. Eren is left momentarily stunned at the sight of his home town, but quickly begins heading toward the breach in the Wall at Levi's urging. Sailing over Wall Maria, Eren prepares to turn into his Titan form. Transforming into his Titan form, Eren quickly uses his hardening abilities to seal the hole in Wall Maria before being retrieved by Mikasa, who carries him back to the top of the Wall. As he takes Mikasa's cloak to replace his burned one, Eren informs Hange that he still has the strength to carry on, and assures Levi that he understands that the scouts still have to kill Bertholdt and Reiner before their mission will be complete.

While going to meet up with the rest of the scouts, Hange orders Eren's squad to take up positions along the top of the Wall after observing a signal flare fired by Erwin. While waiting, Eren observes the Corps soldiers inspecting the side of the Wall and begins to wonder if Armin discovered where Reiner and Bertholdt are hiding.

However, Reiner and Bertholdt and not found, leading Eren and the rest to wonder where to they are.

As the Scouts are waiting and searching for Reiner and Bertholdt, a man and a woman walk up to them.

### Raid on Manehatten arc

In the year 851, Eren works with Hange Zoë and Twilight Sparkle to prepare for Grogar, and Marley's actions against Paradis Island, and Equestria. Eventually, the first scouting ship arrives and Eren uses his Titan form to pick it up and beach it on the shoreline.[197] At a meeting between members of the Eldian Military, Eren supports the plan made by Zeke Yeager and recalls the encounter with Dina Fritz that caused him to activate the powers of the Founding Titan. He reveals to a disappointed Hange and Levi Ackerman that he stayed quiet so that Historia Reiss's life would not be threatened.[198]

Over the next three years, Marley sends a total of 32 scouting ships to Paradis Island,[199] all of which ended up missing or destroyed by Eren and Fluttershy's Titans.[200] At a shooting range the next year, Eren asks Fluttershy if she saw anything from Bertholdt Hoover's memories that could help them. Armin ponders if it is possible for Paradis Island and Marley to resolve the misunderstandings diplomatically instead of fighting and Eren brushes it off. Arguing that everyone still sees them as devils, he reaffirms his position that both Paradis, and Equestria must strike the first blow in order to buy each area time.

Eren later attends a meeting between Kiyomi Azumabito, from the nation of Hizuru, and the heads of Paradis on forming an alliance. When Eren hears that one of the three paths of action would involve Historia succeeding Zeke as the Beast Titan, he refuses to accept the plan.[202]

In 853, while helping his friends assemble a train line, Eren is disappointed to hear that Hizuru has been unable to find additional allies for them. Mentioning that Zeke only has two years left to live before he dies, Eren ponders who should take his Titan when he himself must pass it on. His friends offer themselves but he tells them that they are too important to him and he wants them all to live long lives.[203]

Roughly a year later Thunderlane allows Yelena to discreetly meet with Eren at least once during a festival in Trost. Yelena explains Zeke's plan to euthanize the Eldian race along with his plan to feed his spinal fluid to the Military's officers so that they will not be able to oppose his or Eren's movements. Yelena would later deny advising him to infiltrate Marley on his own.[205] Eren also learns from Yelena that Zeke wishes to speak with him in regards to his true intentions to free Paradis.[206]

Following his meeting with Yelena Eren meets with Thunderlane privately and tells him that he wants them to pretend to cooperate with Zeke's plan. Thunderlane asks what he actually wants to do while pretending to cooperate with Zeke and Eren tells Thunderlane his plan to use the Founding Titan to kill everyone outside of Paradis.

Eren meets with Historia and warns her that the Military Police are planning to feed Zeke to her, advising her to either fight or run to avoid becoming one of the Nine Titans. Historia refuses to oppose the MPs, explaining that she is willing to sacrifice herself if it will save Paradis. Eren reveals his plan to destroy the outside world to her, horrifying Historia. She reminds Eren that most of the people outside the Walls have nothing to do with Paradis but Eren insists that the only way to end the aggression towards Paradis is to wipe out anyone not strictly allied with them. Eren offers to erase Historia's memory with the Founding Titan if she cannot live with the guilt of knowing his plan.

Eren is one of several Survey Corpsmen who journey to Marley's mainland to meet with Kiyomi. Although his companions are thrilled by the new experiences beyond the walls, Eren remains stoic, only commenting on things which he recognizes from his father's memories.[207]

Eren explores Marley, agonizing over the knowledge that he will soon be responsible for killing everyone. Remembering Karl Fritz's desire for the Eldian people to die out, Eren acknowledges that such an outcome would lead to less deaths in total and finally rid the world of the threat of Titans. But even so he finds himself unable to accept such a fate. Eren finds a boy being beaten by merchants for stealing and recognizes from his memories that he is going to save the boy. He attempts to convince himself not to and leave, knowing that he will ultimately kill the boy himself in the Rumbling, but he is unable to stop himself from intervening.

Eren returns the boy to his village, sullenly noting that he was unable to change the future. In tears, he apologizes to the boy.[209] The boy returns to his tent just as Mikasa arrives to look for Eren. He brushes off her worried comments about his reckless behavior, instead commenting on the similarities between the boy's family and their experiences when Shiganshina was breached.

Without warning, Eren asks Mikasa why she displays so much concern for him. As Mikasa stammers that it is because they are family, they are joined by Jean, Armin, Connie, Historia, Twilight, Pinkie Pie, Fluttershy, Reiner, Starlight, Apple Bloom, Sweetie Belle, Scootaloo, Cozy Glow and Sasha. The 104th graduates, and The Mane Eight are welcomed into the tent by the boy's family, and spend the night drinking and carousing.

The soldiers sit in on a hearing between politicians to discuss Eldian mistreatment. They are horrified when the speaker begins calling for the hatred being shown towards Eldians to be redirected towards the Eldians living on Paradis. As the others are listening, Eren quietly leaves the meeting.

Before the end of the Marley Mid-East War, Eren cuts off his own leg and gouges out one of his eyes to infiltrate the Marley military as an injured Eldian soldier. He returns to Liberio and is sent to the hospital along with the other wounded and traumatized Eldian soldiers.

During his stay in Liberio, Eren meets with Zeke and learns about the true nature behind the Ackerman clan lineage. Eren asks Zeke if Mikasa's headaches are something every Ackerman experiences and Zeke claims to have never heard of such symptoms. Zeke tells Eren that he does not believe that Ackermans truly have ingrained behaviors toward a host, instead suggesting that Mikasa simply likes Eren. Eren replies that he only has 4 years left to live, and wishes for his friends to live longer. Zeke asks if Eren would go through with his plan set to save the Subjects of Ymir by euthanizing them. Eren claims that their father was mistaken and agrees with Zeke's earlier claim that Grisha had brainwashed him into following his plan. Eren laments that there would be no suffering had the Eldians never been born and agrees to work with Zeke.

Sometime later Eren overhears a conversation between two Marylean Soliders and discovers that Grogar is working with Marley. Eren relias this imformation back to Willy Tybur, and the two of them come up with a plan to lure Grogar into a trap. Eren disguses himself as a Marlyean solider, and gives General Cavil a letter informing him that Willy Tybur would be making a speech in the Equestrian city of Manehatten. The plan works and Grogar is conviced to attack Manehatten.

Just before the start of the Tybur festival, Eren returns to Equestria and takes up residence in a building near the stage Willy Tybur will be performing a play on. En route, he runs into a random child, and asks them to find to bring Tirek down to where he is. Upon Tirek's arrival the centuar is shocked to see both Eren, and Cozy Glow waiting for him. Tirek asks Eren why he's there, and Eren replies by saying he's aware of Grogar's plan, and that Grogar will be stopped here. Revealing that he has already slit his hand in preparation to transform if need be, Eren insists that Tirek sit with him to listen to the play.

Eren tells Tirek the story of how Reiner, and Bertholdt destroyed his home, and how the Titans ruined the lives of many people on Paradis Island. He admits that he saw Reiner and the warriors as villians, but after getting to know them, and see why they did what they did Eren realized that he too his likely a villian, and that all of them are villians. He ask Tirek why he is on Grogar's side, and why he wants to destroy Equestria. Tirek responds by telling Eren how his father always looked down on him, and that if he took over a massive nation like Equestria, then maybe his father would have given Tirek the love he always desired. Eren that he understands Tirek's turmoil causing the latter to break down and ask that Eren kill him.

Helping Tirek to his feet, Eren says that he now understands that they are the same and declares that he will continue until he wipes out his enemy just as Cozy Glow leaves, and moves herself far away.

After Grogar kills Willy Tybur Eren transforms into the Attack Titan, and tries to kill the ram. Grogar however dodges the attack. Despite failing to kill Grogar, Eren flings himself on top of the military high command in the crowd, killing them. As Eren rampages, the War Hammer Titan emerges, and attacks Grogar.

Eren rushes over to aid the Warhammer Titan in fighting Grogar, but he is attacked by the Lynch King and his minions. The Lynch King uses his ice powers to freeze Eren's feet rendering him unable to move. Eren hardens his Titan's hands in an attempt to block the Lynch King's next attack but fails and the Attack Titan's head is sheered away. Eren emerges from his Titan's nape and calls for Mikasa and Apple Bloom who Attack the Lynch King, at the same time the rest of the Survey Corps attacks the Marleyan Military and the rest of the Legion of Doom.

The Lynch King survives both Mikasa and Apple Bloom's attacks and fires a beam of ice at them. They grab Eren and flee from the Attack Titan's body, barely evading the blast. Eren comes up with a plan to defeat and eat Grogar and ask Mikasa, and Apple Bloom to distrct him and the Lynch King. As the two of them fight Grogar, and the Lynch King together with the Warhammer Titan Eren looks for an opening in which he can grab the ram. Eren looks and notices the Lynch King can't keep an eye on Grogar when blasting his ice attack. Transforming back into the Attack Titan, he manges to grab Grogar while the Lynch King is distracted.

As Eren is about to eat Grogar the Storm King appears behind him and strikes Eren's neck with his staff. With Levi's help, Eren smashes the Storm King into a building but he manges to flee. Because of the distraction Eren fails to notice that Grogar has gotten out of his grip. The Lynch King then traps Eren in a pillar of ice. Eren exits trapped Titan form and immediately transforms once again. The Storm King attacks Eren once again but he is quickly taken down by Mikasa. However before she can kill him he is rescued by Chrysalis.

Eren is then once again able to grab Grogar but before he can kill the ram he is stopped by the arrival of a severaly weaken Tirek. Eren punches Tirek, but Tirek manges to rescue Grogar. Eren tries to get Grogar again, but is stopped when Grogar summons a bunch of Pure Titans forcing Eren, and the scouts to retreat, though Eren states that the mission was still sucessful as they crippled Marley's miltary, leading Mikasa to ask that they go back home. As they grapple up to the airship, Eren promises Tirek that they will meet again.

Once on the airship Eren is met by Levi, who kicks him and orders that he be restrained. Eren does not resist, but insists that nothing in his letter was wrong. Eren waits in a room with Zeke and Yelena aboard the airship when all of a sudden the feel a jolt Jean arrives and informs them that Titans are grabbing the lines of Scootaloo's ODM gear, and are pulling the ship down. As others go out and attempt to stop the Titans Hange berates Eren for having forced the Survey Corps to accommodate his plans and abusing their trust. Eren is unrepentant, saying that the destruction of the Marleyan military leadership has bought them time. When Connie comes in to announce that Scootaloo had sacfriced herself to insure the ship could escape. Eren asks about her final words. Hearing that it was "Keep fighting", Eren begins to laugh.

After returning to Paradis, Eren is taken to a cell underground in accordance with his arrest. As he cleans himself up, Eren mutters that Paradis needs to continue fighting.

### War For Paradis arc

Hange and Twilight arrive and notes that Eren was talking to himself before attempting to make small talk with him. Eren demands to know what they visited him for [238] and Hange chastises Eren for inflaming the rest of the world against Paradis what happened in Manehatten. Eren claims that he can free himself any time. Grabbing Hange through the bars of his cell, Eren demands to know what Hange can do to him, and asks if there is any other way for them to act.

Eren uses his Titan abilities to escape from his cell. He seals up his exit route with hardened skin to prevent his captors from following him.[240] After escaping, Eren meets up with the Yeagerists, a group consisting of Thunderlane and the other recruits who sided with him during his incarceration. Eren declares that they need to locate Zeke.[241]

Eren hears the proposal put forth by Commander Pixis and refuses the offer. He instructs his followers not to negotiate with the Military. He then learns from Griez, one of his new followers, that Hange, Mikasa, Armin and the other Survey Corps soldiers are located at a restaurant where Marleyans work and travels there.

While he instructs Thunderlane to restrain and move them, he goes to a back room where Mikasa, Armin, Apple Bloom, and Gabi are, claiming he wants to solve their issues peacefully.[42] When asked by Armin if Zeke and Yelena have convinced Eren to join their side, Eren brushes it off and merely states everything he has done since the attack on Marley was by his own free will.[242] Mikasa insists he is being controlled but Eren ignores her, explaining how he met with Zeke and spoke brother to brother, learning much about his plan.

Eren states that he wishes for them not to follow him in this final battle, but Mikasa refuses, stating that they will always be by Eren's side. Eren sighs stating that he knew she would say that. He puts down a device, and puts on a mask. The device explodes, knocking out, Mikasa, Armin, Apple Bloom, and Gabi. The last thing Mikasa hears in Eren say, "Im Sorry". Eren then orders them to be taking to Shiganshina.

Later, Eren takes two soldiers and visits Gabi in her holding cell, Gabi ask Eren what his intentions are.

Eren offers to help her save Sweetie Belle, and Cozy Glow in exchange for her issuing a call for help to Marley to root out any possible spies. Eren is caught by surprise when one of the soldiers aims a pistol at him after stabbing the other in the throat.[250] He is unfazed by Pieck's threat of shooting him, reminding her that she considers him a friend. However, Pieck claims that she wishes to help liberate the Eldians.[251] Not trusting her intentions, Eren pricks his finger and orders her to prove herself to him and the Yeagerists. When Pieck offers to reveal where her fellow infiltrators are, Eren heals his finger and orders Pieck and Gabi to be handcuffed together.

Nova, and Gabi try to remind Eren that they're on the same side, but Eren ignores them, and tells Nova to point out any enemies nearby. Nova thinks she spots something and points it out to Eren, suddenly The Lynch King attacks Eren, taking both of his legs. As he transforms, Eren spots a fleet of Marleyan airships approaching their location.[253] Eren trades several blows with The Lynch King, but soon the latter breaks off and begins to retreat. Eren is perplexed at Grogar and Marley's decision to launch a counterattack so soon after the Raid on Manehatten.

Despite Yelena pleading with him to flee underground, Eren decides to fight on his own. Noticing Tirek parchuting down from one of the Airships Eren dedcuces that it was the centuar was responsible for Grogar's quick response. and the two proceed to engage each other. [255]

Initially, Eren overpowers Tirek, using his superior fighting skills and hardening to break Tirek's horns. After Tirek begins to fight back and briefly stuns Eren, The Lynch King attempts to ambush him from behind, but Lara Tybur uses the Warhammer Titan's Spikes repel him[256] Eren is shot in the head with a round from Marley's anti-Titan artillery, leaving his motor skills severely impaired. Lara generates more Spikes to help Eren but she too is then shot in the head.[257] Stunned, Eren is unable to dodge Tirek's attack and is skewered by one of the spikes generated from the ground. Despite this, Lara manages to generate a third set of spikes to impale Tirek once more, and smacks The Lynch King out of the air when he tries to attack him from behind. Eren tries to hold off Tirek and is able to rip through the latter's jaw. Despite this, Tirek continues to incapacitate Eren until he is saved due to Tirek being struck by a projectile thrown by Zeke from atop the Wall.

With Zeke's arrival, Eren begins trying to reach him in hopes of activating the powers of the Founding Titan while Zeke keeps the Legion of Doom at bay.[259] As he grows closer to Zeke's position, Eren is set upon by the Biron and Stella once again but makes short work of them, repeatedly slamming down on their heads and napes killing them. However, this distracts him long enough for another anti-Titan artillery round to be fired into his head again and for Tirek to catch up to him and begin grappling with him.

The fighting is momentarily interrupted by the arrival of Cadance and Shining Armor, who inform Zeke, that Sweetie Belle, and Cozy Glow have accidentally ingested Zeke's spinal fluid. Zeke is undeterred and screams, ordering a transformed Cozy Glow to Attack Tirek. Cozy Glow's Pure Titan proves to be enough to force Tirek to let go of Eren, so Eren exits his Titan and begins running to Zeke on foot. However, before he can reach his brother Eren is decapitated by a blast from an anti-Titan artillery rifle.

As his head lands in his brother's hand, Eren suddenly finds himself standing before a pillar of light in an unknown land. He is greeted by a chained Zeke, who informs Eren that they are standing in the Coordinate Zeke explains that he was able to bring the three of them into the unknown land by touching Eren's head in the moments before he could die, and had asked Ymir to allow Twilight acess as well. They have finally unlocked the Founding Titan's power.

Eren notices a young girl approaching them and Zeke informs them that the girl is Ymir Fritz. Zeke encourages him to take control of Ymir and activate their plan to euthanize all Eldians, but Eren inquires as to why he is sitting there in chains. Zeke explains that the chains are Karl Fritz's vow, keeping anyone with royal blood from acting freely and again asks Eren to begin their plan. However, Eren reveals that he has no intention of following Zeke's plan and was only using him to obtain the Founder's power.[264]

Eren approaches Ymir and requests he be given control of her power, only to be ignored.[265] To Eren's horror, Zeke reveals that during his time waiting for Eren to arrive in the unknown land he discovered a way to erase Karl Fritz's vow, and that Ymir will only obey people with royal blood. Zeke subsequently chains Eren in place, explaining that he has been brainwashed by Grisha.[266] Despite Eren's protests, Zeke promises to free him and begins showing him memories from Grisha's life.[267]

Zeke systematically takes Eren through different moments in Grisha's life on Paradis, detailing how Grisha covertly used his occupation as a doctor to gain information on the royal family in spite of the risk posed to his new family. Eren is largely unfazed by the memories, only surprised to learn that Grisha located the Reiss chapel years before he actually attacked the family and that he still thought of Zeke years after arriving to Paradis. While Zeke is reeling at the revelation that their father still cared for him, Eren moves along to the next memory.[268]

As Eren, and Zeke go through more of Grisha's memories, Zeke asks why Eren betrayed him if he was not brainwashed by Grisha. Eren responds that he has always believed in stealing the freedom of anyone who opposes his own.[269] Eren, and Zeke then go to the memory of Grisha writing about how humanity has not perished beyond the walls, and are caught off guard when Grisha is able to see Zeke for a brief moment.

Eren, and Zeke travel to Grisha's memory of the day he stole the Founding Titan from the Reiss family. As he observes the exchange between his father and Frieda Reiss, Eren becomes increasingly agitated by Frieda's claims that the Eldians must take on the world's wrath for the sins of their ancestors.[270] Despite Grisha's declaration that he will steal the Founding Titan from the Reiss family, Eren is disappointed to see that his father cannot bring himself to carry out his mission. To spur his father forward, Eren reminds Grisha of his fellow restorationists and Faye, ordering him to finish what he has started.

Zeke returns the two brothers, to the present, despite Eren's objection that they have yet to see Grisha's final memories. Eren reveals that four years prior he had been given a glimpse of his own memories of the future while peering into Grisha's memories and Zeke, horrified, orders Ymir to sterilize the Subjects of Ymir. Desperate to stop Zeke's plan, Eren is able to escape his chains by severing his thumbs against the shackles and races to try to stop Ymir.[272] He embraces her and begs that she give him her power so that he can end the world, promising that he will not force her to help him. He recognizes that she is neither a slave nor a deity, she is only a human being and she has the right to choose if she wants to remain in the Coordinate forever or help him end it all. As Zeke desperately tries to stop him, Eren asks Ymir if she was the one who led him to the Coordinate, musing that she has been waiting 2,000 years for him to arrive.

In Shiganshina, Eren's body transforms into the Founding Titan as Shiganshina's walls begin to crumble.[274] He then uses the Founder's power to telepathically communicate with all of the Subjects of Ymir.[275] He reveals that the hardening of the Walls has come undone, and declares that the Wall Titans will destroy all life outside the island.[65]

### Rumbling arc

Eren and his Titans arrive at Marley's coast only to find it guarded by the Global Allied Fleet. However, the fleet proves to be ineffective against Eren's Colossal Titans and is immediately wiped out. The land artillery on Marley is also unsuccessful in stopping the advancing Titans, causing the soldiers to retreat to higher ground. As his Titans begin the destruction of Marley, Eren remembers the death of his mother and reiterates his desire to destroy every last one of his enemies in the world.

While he is advancing, Eren summons each of his friends to speak with him in Paths individually. He reveals to each of them his true intentions, to become a threat to the entire world so that they can kill him and earn the favor of the nations outside of Paradis. He also reveals that his death will permanently destroy the Power of the Titans, causing all Eldians trapped as Pure Titans, including Connie's mother, to return to their human forms.

When Eren speaks to Cozy Glow, he shows her that if she didn't reform, then she Chrysalis, and Tirek all would have been turned to stone. He lets Cozy Know that he's glad he was there to save her from her dark path, and Cozy Glow states that she will miss him after he dies.

When Eren speaks to Apple Bloom, they go through all the hardships of her life. Eren reminds Apple Bloom, that while bad things will always happen, there are postives to the negetives. Apple Bloom thanks Eren for always sticking by her, no matter what.

When Eren speaks with Mikasa, he shows her a vision of a possible future in which they decided to run away together while in Marley and live out the rest of their lives together in peace and isolation. After spending some time together in the vision, Eren asks Mikasa to forget him after his death.

When Eren speaks with Armin he tries to apologize for the way he treated him at Niccolo's restaurant, but Armin says that he should be more worried about apologizing to Mikasa. Armin worries that the world will try to retaliate for what Eren did, but Eren reveals that he succeeded in wiping out 80% of the world's population before he was stopped. The nations will not be able to launch any meaningful counterattacks for the foreseeable future. Armin tries to insist that there was a better way but Eren ignores his protests and asks Armin to follow him.

Eren takes Armin to a volcano to show him the "liquid fire" that he read about as a child, lava. Eren reveals to Armin that he has come to understand that the reason Ymir Fritz remained servile to the royal family even centuries after her original master's death is because she genuinely loved him, despite the abuses she suffered by him. Although he does not understand the woman fully, he knows that it was Mikasa who managed to free her from her servitude. Eren claims to not know why Mikasa is important to Ymir, only that every action he has taken since he received his future memories has been done in the service of Mikasa freeing Ymir.

As he reflects on everything he has done, Eren confesses to Armin that he can no longer think clearly, as the combination of past and future memories in his head have rendered him unable to distinguish what is past, present, and future. His warped perspective of time has caused him to take actions to ensure history should play out the way he remembers it, even using his powers to go back in time and influence Dina Fritz's Titan to eat his mother.

Armin takes Eren to see the ocean and asks him if he believes Mikasa can move on from him. Eren claims he does not know and Armin punches him, enraged at the way he has been treating Mikasa.

Armin begins ridiculing Eren, joking that Mikasa will forget about him quickly, and Eren finally breaks down and admits that he does not want Mikasa to love anyone but him. After composing himself, Eren confesses that he does not want to die. Armin tries to convince him that he can keep living, but Eren reminds him that the world will never forgive what he has done.

As a ruined landscape of trampled corpses appears before them, Eren confesses that he would have continued Rumbling even if his friends had not tried to stop him. Armin demands to know why, but Eren claims he does not know. Eren tells Armin that he will be temporarily erasing his memories until his death and Armin gives him a seashell, thanking him for everything he has done for Paradis's sake. The two embrace and Eren tells Armin that he is confident Armin will be able to save humanity after his death.

However Twilight Sparkle then tells Eren of another idea they can do. She can teleport Paradis to the other world as no one there hates Eldians. After some consideration Eren agrees but states that the rest of the world must believe that he is dead.

As he approaches Fort Slava, Eren summons Mikasa, Armin, Apple Bloom, Cozy Glow, Sweetie Belle, Jean, Connie, Sasha, Historia, Levi, Erwin, Moblit, Reiner, Nova, Twilight, Pinkie Pie, Fluttershy, Sunburst, and Starlight to Paths to speak with them. His former comrades beg him to stop the Rumbling, but Eren tells them that he has no intention of stopping. He explains that he will take all of the world's freedom so that it cannot take his, but he promises not to deny the alliance's freedom to thwart his plans. However, Eren reinforces his intent to destroy the world, refusing to negotiate on any terms and stating that the only thing to stop his advance would be his death.

Marleyan airships are launched from Fort Salta to try to stop Eren's advance[277] and begin dropping bombs on his Titan. In response, Eren dispatches the Beast Titan to shoot them down. Eren and the Beast make quick work of the airships, but his former comrades arrive and manage to evade the Beast Titan's projectiles long enough to reach him and engage him directly.

As his friends attempt to reach his nape to destroy it, Eren and Ymir begin generating more Titans on his back to defend him. Despite this, the soldiers eventually manage to reach Eren's nape and blow it up, severing his Titan's head from its body. Fluttershy then transforms atop his Titan in an attempt to kill him.

This proves to be ineffective, and Eren's head transforms again into a new Colossal form to continue its march. He is met by Fluttershy, who chooses to engage him in a hand-to-hand fight with her Colossal Titan form. Eren proves to be the better fighter between the two, but Fluttershy manages to immobilize him long enough for Mikasa to enter his Titan's mouth and behead Eren. eadter his behading Eren once again telepathicly speaks with His friends, The Eldians of Paradis as well as the warriors families who understand Eren's actions. Eren explains that Paradis and all it's inhabitnts will be telported to the pony dimension, and that Eldians will no longer be able to turn into Pure Titans, but the Nine Titans will remanin in order to defend Equestria.

One month after the Rumbling is stopped Eren watches as the Map Summons Cozy Glow, Apple Bloom, and Historia to Las Peagus. He later saves them from a group of bandits.

Six months after the Rumbling Eren attends a party thrown by Pinkie Pie to celebrate the birth of a brand new baby filly. However Eren's peaceful day is intteruptted when a new monster arrives in Equestria and starts killing ponies.

## Alternate Reality

### Lost in the Cruel World

In the year 844, Eren accompanies his father, Dr. Jaeger, to the Ackermanns during a medical visit. He is introduced to Mikasa and the two begin wandering the forest nearby. Eren tells Mikasa that he heard her mother is pregnant, to which she confirms and says her mother believes it to be a boy. Eren remarks that if the child is a boy, he hopes that he will become a soldier. He reveals to Mikasa his dream of joining the Scout Regiment and exploring the outside world.

Suddenly, the two hear howling in the distance. Mikasa becomes worried, saying that her father does not want her going deep into the forest, but Eren runs ahead on his own to investigate, prompting Mikasa to follow him. The two come across the ruins of a campsite overrun by rabid dogs that have killed a trio of travelers. The dogs spot Eren and Mikasa, then slowly approach them, but suddenly turn their tracks and leave. The two return home and inform their parents of the location of the corpses they saw.

Over the course of Dr. Jaeger's visits, Eren continues playing with Mikasa and the two quickly become friends. He tells her of his friend, Armin, who is intelligent and reads a lot of books, and is also the one who told him about the outside world. Eren mentions that they will one day explore the outside world together. During the next visit, he arrives with many injuries to his face. Eren talks to Mikasa about the outside world and describes the ocean as being a large amount of salt water that is big enough to the point merchants could never sell all of its salt.

He continues that the outside world also has fiery water, lands of ice, and land all covered in sand. Mentioning that the people who fought him are cowards who are content with living ignorant within the Walls, Eren reiterates his dream of joining the Scout Regiment to see the outside world.

When Mikasa is sent to Shiganshina District, Eren meets her upon arriving. Hearing the bell that signals the return of the Scout Regiment from an exterior scouting mission, Eren eagerly heads to see the Scouts, which return in shambles.

In front of them, two civilians comment on the scene, saying their taxes are being wasted on feeding the Titans. Eren strikes one of them in anger, and the man takes Eren into a nearby alley. The man begins to mercilessly beat Eren as Mikasa watches in shock. That night, Eren is taken to his home and his wounds are treated.

Eren stops going to Mikasa's house for sometime, and when the Ackermanns move into Shiganshina to be closer to Dr. Jaeger, Mikasa questions Eren on why he stopped visiting her. Eren tells her that the Scout Regiment has been disbanded for the lack of results, and the gate leading to the outside of the Wall has been sealed off.

Mikasa is relieved that Eren will not be able to leave the Walls, but he adds that he will be leaving with Armin using a hot air balloon they were building, and it is why he could not visit her. Mikasa asks Eren to take her with him, and he responds by wrapping his scarf around her and mentioning a path to a nearby forest, telling her that she can return it to him there in three days. At the time of their leaving, the balloon fails to gain enough altitude and Eren pushes Armin to safety, before it crashed into the Wall.

## Abilltes

### Martial arts

Originally, Eren's only noteworthy trait was his natural physical strength, which stemmed from having to defend his friend Armin from bullies who were bigger and stronger. As he grew and joined the 104th squad, he trained extensively in hand-to-hand combat.[25] While hand-to-hand fighting would appear useless due to the massive physical differences between humans and Titans, these skills gave Eren a powerful edge when fighting other Titans in his own Titan form.

### Omni-directional mobility gear

At first, it is shown that Eren is not very skilled with the ODM gear. During the initial balancing tests, he kept tripping and smacking his head on the floor. People mocked him for this. Eren pleaded for help from everyone but the only advice they could give Eren was that he needed to clear his mind and focus. On his last attempt, Eren did just that and stayed upright for a short period of time before tipping over and hitting his head. Seeing this, the commandant, Keith Sadies told Thomas Wagner to swap equipment with Eren and for Eren to try again. Eren did so and balanced with ease. The commandant then told Eren that his equipment was damaged and that it was a miracle that he managed to stay upright at all.[25]

Eren is not shown using the gear as much as other members of the Scout Regiment, but he was able to hold his own against the Colossal Titan for a short period of time when it reappeared for the first time in five years.[1] His most significant use of the ODM gear was shown during the Attack on Canterlot, where he was able to use it to knock out Tirek and caputre Cozy Glow.

### Attack Titan

During the first Battle of Trost, Eren was swallowed whole by a Titan, and inside the stomach-like cavity saw other fellow recruits lying dead/dying, one wanting her mother before sinking in stomach acid. This sight combined with intense feelings of desperation and his drive to exterminate all Titans awoke his ability to transform into a Titan. In this form, he is a 15 meter tall Titan, with shoulder-length black hair, pointed ears, a long nose, and a gaping, skeleton-like maw lacking lips. Unlike most other Titans, Eren's Titan form is considerably more muscular and defined; making him much stronger than even similar-sized Titans while his intelligence and military training, allow him to out-maneuver and dispatch entire groups of Titans with ease. A transformation takes a heavy toll on Eren’s body and requires large amounts of stamina. As a result, he has displayed several symptoms when he over-exerts himself such as a nosebleed, pale skin, and labored breathing. In some cases, Eren is rendered unconscious for a short period of time after a Titan transformation.

Initially, Eren has no control over his actions when he first transforms into a Titan and is unable to remember any actions that occurred during the first Battle of Trost. He is in a “dream-like state” and fails to remember how to transform in the first place. However, Eren recalls fragmented memories of his father by seeing the key to the basement of his old home and is able to successfully transform to protect Armin and Mikasa from certain death. It has been shown that with more transformations, Eren retains more of is intelligence being able to form rational thoughts. At the beginning, during the second Battle of Trost, Eren in his Titan form attacks Mikasa but ultimately plugs the hole in Trost's gate after Armin forces him to wake up. His Titan form, combined with his growing experience and his hand-to-hand combat skills, allowed him to kill over 20 Titans in his first transformation.[26]

Eren, like all others with the power of the Titans, must physically harm himself in order to transform into his Titan form. However, lack of a determined goal and resolution for it inhibit his ability to transform as shown when he cannot transform at first to confront Annie Leonhart. Within Titan transformations, he has displayed the ability to partially transform, as shown when he protected Mikasa and Armin from a cannonball by forming the upper torso skeleton, complete with arms and a skull with some muscle tissue. From his suppressed memories, Eren believes that the full truth of his Titan powers, as well as a way to defeat the Titans once and for all, is located in the basement beneath the ruins of his family home.

* **Regeneration:** Eren’s Titan form has demonstrated the ability to automatically heal any injury sustained in battle and also to regenerate entire limbs. Unlike Annie Leonhart, Eren has not shown the advanced ability to focus regeneration to one wounded area of his Titan form. His healing factor was fast enough to heal an entire lost hand in mere seconds to an entire arm in minutes. This ability is useful to Eren as, when he fights, he often loses entire limbs in his Titan form. While in his human state, Eren can also regenerate entire lost limbs, as seen after he lost his arm and leg to a Titan, he regrew them.

* **Enhanced Strength:** As a result of Eren’s Titan form being much more muscular than other Titans, he is much stronger in terms of physical strength. During his first transformation, Eren was able to decapitate a 15m Titan with a single punch and kill a 7m Titan with little effort. With both arms lost, he was also strong enough to bite into the neck of a large, abnormal Titan that ate Thomas and lift it up above his head. With enough force, Eren was able to throw the abnormal into another Titan hard enough to knock them both into a building.[4] Against the Female Titan in the Titan Forest, Eren’s Titan form had enough physical force to leave large craters in the ground, as well as lift the Female Titan into the air with a punch. Ultimately, Eren’s greatest display of strength was when he lifted a giant boulder, albeit with difficulty, carry it across a large distance, and slam it down to seal the hole in Trost's gate, producing a large shock wave.

* **Enhanced Endurance:** Perhaps Eren's most notable trait of all is his ability to maintain levels of activity for an extended period of time. Eren’s first transformation carried on long enough to incapacitate 20 Titans in total. In battle, even after receiving massive amounts of damage from the Female Titan, Eren can carry on fighting, despite the handicaps that he suffers. He was also able to fight against the Armored Titan for a period of time and gain the upper hand. Eren’s endurance in his Titan form was enough to allow him to sustain the effort of hoisting a huge rock on his back, carry it over a large distance, and seal the hole in Trost's gate shortly before collapsing.
* **Hardening:** After consuming a bottle labeled "Armor" from Rod Reiss's bag, Eren's Titan form gained the ability to harden its body, as well as create a web of pillars that appear to originate from his Titan body. The hardened pillars are incredibly durable, capable of preventing a cave-in, as well as shielding Squad Levi from the heat of Rod Reiss's Titan form. The constructs, as well as Eren's Titan, also retain their durability and hardened state even after he has been separated from his Titan body. After two months of training with Hange Zoë, Eren is able to seal a cave with his hardening powers and reinforce the hole the Colossal Titan left in Trost and Shiganshina. However, constant use of this power can overwhelm Eren and make him weak. By focusing his hardening in one place, it gets even stronger. Focusing in his fists gives Eren a hardened punch, capable of easily breaking the Armored Titan's armor.
* **Future Memory Inheritance:** As part of the Attack Titan's unique abilities, Eren can reveal his own memories to his predecessors, giving them insight into the future. He gives memories of the future to his father Grisha, selecting the ones that would suit his purpose. By doing so, he indirectly gives his younger self insight into his own future via Grisha's memories when Eren kisses Historia's hand.

### Founding Titan

With the power of the Founding Titan that Grisha Yeager stole from the Reiss family, Eren possesses the ability to control nearby Titans, causing them to relentlessly attack his chosen target. However, this ability can only be used while Eren is in contact with a Titan of royal blood.

The first time he uses it is entirely by accident, by touching the palm of Dina Fritz's Titan, causing nearby Titans to attack and devour her, and setting the same Titans upon Bertolt and Reiner. While it is shown that others with the power of the Titans can sense the activation of his power, it is unknown whether it is possible to use it to influence or control other human-controlled Titans.[284]

Possession of the Founding Titan is the reason many groups have expressed an interest in Eren, including Marley's Warriors in their Paradis Island Operation, and Rod Reiss, the former patriarch of the Reiss family.

Four years after Eren's first, and accidental use of it, Eren is finally able to unlock the full capabilities of the Founding Titan after freeing the soul of Ymir Fritz from the control of her descendants, giving him access to all of the Founder's powers. With the full power of the Founder, Eren is able to control all of the Wall Titans, create a skeleton that towers over all of them, and can telepathically communicate with all of the Subjects of Ymir. Later he demonstrates the ability to generate one of the nine titans, the Beast Titan, potentially without Zeke Yeager (the actual inheritor of the Beast Titan) and controls it to attack air ships.

* **Grisha Yeager** - Eren greatly looked up to his father Grisha, who usually supported his son and did not show any visible objections to Eren's wish to join the Survey Corps when he was old enough to enlist; he did express some frustration and later sadness by his father's sudden disappearance after Wall Maria fell. Upon remembering the mission his father left him before he vanished, Eren expressed anger and bitterness at the fact that Grisha had kept secrets from them, on top of abandoning himself and Mikasa. Eventually, Eren is shown memories of his father thanks to Historia and Rod Reiss in which he learns his father had indeed returned after the fall of Wall Maria; in addition, Eren also learned that his father was the one who gave him his powers and he was dead because Eren devoured him. Eren became distraught upon realizing he killed his own father but became horrified that the latter was a Titan that killed the Reiss family. He tried to persuade Historia that they do not have to follow the wishes of their fathers, showing he gained some resentment for Grisha. This would last for several years until he saw his father's memories and saw why he kept his past a secret from him. This gave Eren a better understanding of his father's actions and why Grisha kept secrets from his family. This understanding was seen again after he met his grandfather who broke down after reflecting on his past treatment to his son. While appreciating his father, Eren expressed frustration at Grisha's reluctance to take the Founder and influenced him in order to fulfill his duty.
* **Carla Yeager** - Eren clearly loved his mother Carla very much, although they would constantly argue over his wish to join the Military and as a result would often ignore her warnings or advice. During the fall of Shiganshina, he struggled in vain to rescue her from the rubble of their demolished home despite being surrounded by Titans and wanting to run away from the danger. Unfortunately, he was ultimately forced to watch a Titan devour her as he was hauled to safety. Her brutal demise and his own powerlessness to prevent it severely traumatized Eren. In his grief, he expressed remorse for continuing to disobey and argue with her in their last moments together, and her loss fueled his virulent hatred of all Titans. As he contemplated the future years later, he would ponder on his mother's opinion of the oncoming calamity he would inflict on the world.

* **Mikasa Ackerman** - Eren has a complex relationship with his adoptive sister. He often displays a brusque, casual attitude with her, which belies their deep bond and care for each other. While Mikasa is more open with showing concern for him, Eren only does so when she is injured or in distress. Despite his blunt exterior, he is always looking out for her, and will not hesitate to comfort or reassure her when he senses that she needs him to. He would even go as far as to call himself a monster to ensure that she would not be targeted by the prosecution. Like typical siblings, they do not always agree, but Eren will usually not stop Mikasa from doing what she wants, so long as it is within reason. He also seems to harbor somewhat of an inferiority complex towards her, due to her outstripping him in both strength and battle skill. This is further compounded by her desire to constantly keep tabs on him and keep him out of trouble - a habit he generally views as annoying. At times, he feels so stifled by her protectiveness that he openly lashes out at her, telling her not to treat him like her "little brother." Despite this, he will attack anyone and anything that threatens Mikasa, even meeting a punch from a 14 m class Titan bare-handed simply to protect her. After going across the sea, Eren asks Mikasa about what he means to her. When she replies that he is family, the rest of their friends arrive and interrupt them, disappointing Eren. After joining the Yeagerists, Eren breaks all ties with Mikasa and the Military; when Mikasa tries to bring him around, he calls her an obedient slave and claims that she has become the thing he hates most in the world. While this deeply hurts her, she was willing to support Eren when The Legion of Doom, and Marley launch an Attack on Equestria, and Paradis following Eren's murder of Grogar, but chooses to leave behind the scarf he gave her years ago. After Eren announces that he has started the Rumbling, Mikasa was horrified at this revelation, but she was later unable to respond to Annie when she was asked if she could kill Eren when necessary. Mikasa is still willing to hold out hope for Eren to come to his senses.
* **Armin Arlert** - Armin was Eren's closest friend, who inspired him to dream of the world beyond the Walls (and in doing so, became partially responsible for motivating him to join the Survey Corps). During their childhood, they were snubbed by other children as well as adults for their "heretical" ideas. Armin himself is frequently targeted by bullies, whom Eren (sometimes with Mikasa in tow) would constantly try to fend off. This pattern would continue into their teenage years, with Eren leaping into action to save Armin from danger, not caring if he himself is harmed in the process; the most memorable occasion being the day Eren (sans his left leg) snatched Armin from a Titan's jaws and got swallowed in his place (losing his left arm in the process). Despite Armin considering himself as burdensome, Eren greatly appreciates his quick-wittiness and brilliant judgment (it also did not miss him that Armin's quick thinking had saved his and Mikasa's lives in 845). Eren's confidence in Armin is so great that he would entrust him with his life with no hesitation if asked to do so. However, four years later, some friction has developed between them due to differing opinions on how to deal with Marley and the other nations. Like Eren's relationship with Mikasa, his friendship with Armin is presumably shattered after he joins the Yeagerist movement. Later, Armin correctly deduced that Eren is only pretending to go along with Zeke's plan, realizing that Eren is just using Zeke to unlock the Founding Titan's powers. After Armin realizes that Eren has started the Rumbling- shortly before Eren's revelation- he numbly contemplates the consequences with Jean. Despite this, he is still unsure of even thinking about killing Eren, as demonstrated many times in his conversations with Annie. Armin still hopes that he and Eren could still discover the world together.
* **Hannes** - Prior to the fall of Wall Maria, Eren was constantly frustrated by Hannes being a habitual drunkard in the line of duty. Despite not having saved Carla from the hands of the Titan, Eren borne no ill will towards him, and instead looked up to him with respect and understanding. Eren was driven to the brink of despair as he witnessed Hannes being eaten alive by the Smiling Titan, and he remains tormented by his loss despite managing to avenge him. In memory of Hannes and his sacrifice, Eren has become more determined than ever to discover the truth about the Titans and punish any guilty parties.
* **Jean Kirstien** - As Eren's main rival, his temperament is the very antithesis of Eren's. Where Eren is hotheaded, he is collected; and Jean is pessimistically pragmatic as Eren is idealistic. Jean believed anyone who wished to join the Survey Corps was a suicidal fool, while Eren regarded those who looked down on the people who wanted to fight the Titans with contempt. Initially, they are able to resolve their differences in a civil manner despite starting off on the wrong foot. However, this friendliness was short-lived, and a fierce rivalry budded between them, with the two constantly provoking each other and getting into fistfights. In addition to insulting Jean to his face, Eren also seems to be fond of saying Jean has a "horse-face" behind his back. In the wake of the Battle of Trost, Eren and Jean seem to have set their differences aside and stopped antagonizing each other. Though they still quarrel as much as before, their animosity has noticeably lessened. After Eren reveals his genocide plan, Jean was willing to justify Eren's actions as a measure of self-defence; sacrificing the rest of the world for Paradis' safety.
* **Levi Ackerman** - As humanity's most formidable soldier and Eren's superior officer, Levi commands great respect and admiration from him. Eren bears no grudge against Levi for beating him before the entire court during his trial, recognizing that it had been a necessary measure to secure his life. Aware of the vast gap in experience between them, Eren strives to learn as much as he can from Levi, heeding his advice with little hesitation and trusting his judgment. During the thirty days he shared living space with Levi's squad, he also seems to have well understood Levi's standards of cleanliness. A notable example of this is when he is shown diligently cleaning his new squad's base (and fretting over the somewhat slovenly habits of his peers) in anticipation of Levi's arrival. As Eren has spent more time with Levi and witnessed how harsh he can be to his peers, he is able to marvel at and encourage the notion of punching Levi back.[289] Later, Levi becomes a sort of mentor towards Eren, giving him advice in his times of doubt. As their trust in each other grows, Levi becomes more patient with Eren and forgives his mistakes, nurturing his growth as a soldier, and as a vanguard for humanity's hope. In spite of this, Eren would break Levi's trust and respect when he orchestrated the raid on Liberio, physically reprimanding his insubordination and arresting him after the battle.
* **Erwin Smith** - Eren briefly meets Erwin as a child the day Shingashina when the Survey Corps returns from a mission. Erwin sees Eren in the crowd smiling in awe but Erwin looked away in sadness due to the heavy losses sustained. Five years later Eren is officially introduced to Erwin following the Battle of Trost and Erwin expressed interest in recruiting hin into the Survey Corps so they could reclaim Wall Maria, and acted in Eren's defense during his hearing. Though Eren was at first discomforted by Erwin's willingness to take big risks and endanger lives he gradually came to understand Erwin's actions when faced with increasingly dangerous threats to humanity.
* **Annie Leonhart** - Eren greatly admired Annie, and was trained in her unique fighting style during their years as cadets. He considered her to be a kind person beneath her cold exterior and credited her with making him aware of the contradictions within the military system. However, he was eventually horrified to learn of her identity as the Female Titan. Even as Annie herself transformed in front of him, a part of Eren refused to accept her betrayal; and he became so conflicted that he was initially unable to summon the will to fight her (Mikasa even went so far as to suggest that his hesitation was due to him harboring "special feelings" for her).[35] Even as he went toe-to-toe with Annie, he continued to brood over what had driven her to slaughter their comrades.[36]
* **Reiner Braun** - Eren once described Reiner as being like an older brother to him, and admired him as a "strong, capable guy." The two were shown to have trained together, and Reiner taught him the importance of the duty soldiers have to protect the weak. It can be said that he was the one Eren looked up to the most in his career as a soldier. However, once he and Bertholdt Hoover revealed their identities as the Armored and Colossal Titans, the friendship they had was destroyed. Later on in Equestria though, their friendship is repaired
* **Bertholdt Hoover** - Though friendly, the two were not particularly close. Bertholdt expressed admiration for Eren's courage and the strength of his conviction to fight even after experiencing the horror of a Titan attack. After Bertholdt and Reiner revealed their true identities, Eren discarded the time they spent as friends in during training and viewed Bertholdt and Reiner as traitors, vowing to kill them slowly and painfully. Eren eventually abanodend this desire, he watched in sadness as Bertholdt let himself be eaten by the Pure Titan form of Fluttershy
* **Historia Reiss** - Initially, Eren did not interact with Historia very much, and had in fact secretly disliked her because he felt she was a phony. However, once her true identity was revealed and her demeanor began to change, Eren began to see her as more "honest" and warmed up to her. He even accepted being eaten by her if it meant the annihilation of all Titans, which shows deep confidence in her.[292] Despite this, he still wishes for Historia to lead her own life. Eren omitted that coming into contact with a royal blooded Titan would enable him to use the Founding Titan's abilities, fearing that sharing information he considered uncertain at the time would cause Historia to be turned into a Titan. Eren also argues against the plan of Historia becoming the next inheritor of the Beast Titan, showing that Eren cares for her deeply. However, he was not above pressuring Historia into not divulging his genocide plan, showing duplicity in his actions.
* **Connie Springer** - As members of the same trainee squad, Eren and Connie shared many experiences together and get on well with each other. In the early days of their training, Connie was among the trainees who eagerly questioned Eren about the Titans' invasion in 845. Though he only enlisted in order to have a good reputation in his home village and initially wished to join the Military Police Brigade, Connie was so moved by Eren's passionate conviction to defeat the Titans that in the end, he decided to join the Survey Corps instead. Though their backgrounds are different, the two now find themselves sharing a similar plight. Both their families and homes are reduced to little more than memories, and each carries the burden of his mother's cruel fate. However, following Eren's murder of Grogar Connie starts viewing Eren contemptuously and sees him as a different person from the one he befriended, and states he is ready to kill Eren should the need arise.
* **Hange Zoe** - When Eren first met Hange, he was put off by her obsession with him, finding it creepy. After learning about Hange's work on Sonny and Bean, however, and Hange's reason for being so obsessed with Titans and change (which he could relate to), he became one of the first people to be interested in their work and was saddened by the deaths of the Titan test subjects (although he still found Hange weird, especially after she kept him up the entirety of one night). After four years, their relationship sours when Hange noted that Eren's actions in Canterlot made both Paradis, and Equestria targets to Marley; furthermore, Hange expressed anger over how Eren abused the Survey Corps' trust in him for his own selfish desires. Their relationship took another blow when Eren physically assaulted Hange, slamming her against the bars of his cell after returning from killing Grogar and being arrested for his actions.
* **Marco Bodt** - Eren had great respect for him, and recognized his tendency to think of the group before himself. He also stated he would have liked to be on his squad, and considered him a good leader. Upon learning of Marco's death, Eren was initially in a state of disbelief and was visibly stricken when Jean reaffirmed that the news was indeed true.
* **Petra Ral** - Among the members of the squad assigned to protect Eren, Petra seemed to be the one closest to him. She was among the least eccentric and most friendly of the members, and Eren admired her not only for her skill but for her open acceptance of him as a comrade as well. Witnessing her demise at the hands of the Female Titan was a devastating blow to him, and he remains remorseful of making the decision that led to her death.
* **Ouro Bozad** -  Of all the members of Levi's squad, Oluo gave Eren the toughest time, often badmouthing and blustering at him. Despite his senior's somewhat obnoxious and boastful demeanor, Eren still respected Oluo as a top-tier soldier. In return, Oluo once threatened Eren but saw his mistake and apologized for it though he said so in his arrogant ways. His violent death was perhaps the trigger event that caused Eren to finally transform into his Titan form to stop the Female Titan in its tracks. Along with the other members of Levi's special squad, his death still haunts Eren.
* **Eld Jin and Gunther Schutz** - Eren admired the two soldiers; both in their skills, serious attitude and devotion to humanity by facing the Titans. Their deaths partly fueled Eren's rampage against the Female Titan, and he is still filled with regret over not choosing to fight while they were still alive.
* **Zeke Yeager** - Zeke is Eren's older half-brother. They first meet in Shiganshina when Zeke tells Eren everything. Zeke told Eren that he understands him and wants him to believe him that they both were victims of their father's brainwashing and said that someday he will come to save him.[294] Eren was very surprised Zeke had a resemblance to his father and wondered about the connection until he saw his father's memories and discovered their relationship, becoming shocked that his father had a previous family. Of particular note, Zeke's turning on their father indirectly led to Eren's birth and he also learned that Zeke's mother was the Titan that killed Eren's mother. Durning their time in Equestria, Eren and Zeke met secretly  learning numerous secrets and creating a mutual understanding between them.[295] The two now work together, and plan to meet once again to set in motion their secret plan.[296] However, Eren later reveals he lied to Zeke and ultimately refuses to go along with the latter's euthanasia plan. Following the revelation that Eren used the future memory inheritance ability of the Attack Titan to compel their father into killing the Reiss family and steal the Founding Titan, Zeke becomes disillusioned with his brother.
* **Mr. Yeager** - Eren saw his grandfather through his father's memories but what opinion he had of him was unknown. Four years later, he met his grandfather in person while disguising himself as a wounded soldier. He was surprised by the latter's appearance but kept it to himself to avoid suspicion. In a talk Mr. Yeager ask Eren about his realtionship with Apple Bloom as he finds it interesting.  Mr. Yeager soon confided in him about his past which led his son to form a movement and slowly blame himself for raising him to follow in his footsteps. Eren was solemn at his grandfather's outburst but appeared to understand the choices of his father.
* **Yelena** - Eren shares Yelena's concern regarding Marley's desire to destroy the Eldians and works along with her to take over the Eldian military. He is willing to hear her opinion,[299] but insists that he is not being controlled and is following his own sense of judgment.[300] Eren seemed to follow Yelena's instructions, but his complicity in her and Zeke's plan would turn out to be ploy, and Yelena's trust in him evaporated as she witnessed the start of the Rumbling.

* **Apple Bloom**- Apple Bloom and Eren have a very close realtionship, Even before they met, they've both recived visions of each other, and were able to telepatcly speak to each other. Eren has saved Apple Bloom's life many times, the first time being when he saved her durning Chrysalis invasion at the Royal Wedding. Another time when the Pony of Shadow returned Eren allowed Apple Bloom to use one of the Founding Titan's abilites. While walking towards Canterlot, Eren tells Apple Bloom how she's probaly the main reason he wants to protect Equestria. and he and Mikasa even adopt her, after she loses her entire family. However Apple Bloom is horrorfied when Eren activates the Rumbling, and works with the others to stop him

* **Cozy Glow**- Eren also has a very Close relationship with Cozy Glow, He did not belive she was naturally evil and was sure there was a reason behind her behavior. His suspsicons were confirmed when he learns that she was abused by her parents, and when her parents kidnap her, Eren goes to extrems to save her. Cozy Glow is shocked by Eren's plan to destroy the world.
* **Sweetie Belle**- Eren and Sweetie Belle get along wonderfully with each other, Sweetie Belle even calls him Uncle Eren, much to his embarssement, and Mikasa's delight
* **Scootaloo**- Eren and Scootaloo didn't interact much, but when they did, they got along incredibley with one another. Eren blammed himself for Scootaloo being eaten by a Titan, despite Apple Bloom and Sweetie Belle, telling him it was not his fault.
* **Twilight Sparkle** - Eren and Twilight have a postive realtionship. When they first meet, Twilight shows concern for Eren when Tirek nearly defeats him. They later work together to distract Tirek and Cozy Glow.
* **Fluttershy** - Fluttershy first hear's of Eren after Reiner, and Bertholdt reavel their past to her, and the others. When Fluttershy learned that Eren told Reiner that he would kill both him, and Bertholdt slowly and painfully she was shocked, but understood why Eren would be angry with the two of them. Eren, and Fluttershy offically meet durning Grogar's first assualt on ponyville durning which Fluttershy saw how even though he hardly knew anyone in Equestria Eren was willing to protect the citzens as if they were his own people. Later when both Fluttershy and Nile are on the brink of death Eren insist that the Titan injection be used on Fluttershy. He is relieved when Fluttershy is brought back, and gently hugs her. He then comforts her when she begins to have a small anxiety attack do to now being the Colossal Titan imforming her along with the other Titan shifters (Sans Porco Galliard) That she's not alone.
* **Pinkie Pie** - Though finding her kind of annoying, Eren still cares deeply for Pinkie Pie, and brutally attacks a stalion for making her cry.
* **Princess Celestia** - Eren has a great amount of respect for Celestia, and sees her as a great ruler, even going as far as to ask her for advice when he is facing problems
* **Thunderlane** - Eren did not think highly of Thunderlane due to his insistence that Cozy Glow be left to the mercy of her abusive parents However, he would later set aside any prior animosity, allowing the two to work together as part of the Yeagerists. Eren would put great trust in Thunderlane, confiding in his genocide plan long before its execution.
* **Grogar**- Eren despises Grogar, and vows to kill him, when Grogar first sees Eren he instantly recgoinzes him as a threat and goes to extreme lengeths to either capture or kill Eren.
