Armin Arlert

Armin Arlert is one of the two deuteragonists (alongside Mikasa Ackerman) of the Attack on Titan franchise. He is a refugee from Shiganshina and Eren Yeager and Mikasa Ackerman's best friend from childhood. 
Although he is physically weak and hates having to rely of Eren and Mikasa, Armin's strategic abilities and intelligence more than makes up for his physical foibles and have saved Eren and Mikasa multiple times. He is instrumental in discovering the identities of the Titan infiltrators, and becomes one of the Survey Corps' most vital members. In fact, Armin's brilliance is not only recognized by his comrades and superiors alike, his strategic capabilities can reach and appeal directly to Erwin Smith, the supreme leader of Survey Corps, bypassing typical military chain of command.
During the Battle of Shiganshina, Armin sacrificed himself to district Bertholdt Hoover (who was the Colossal Titan), allowing Eren to cut him out from his nape. He was later given a Titan serum so he could devour Bertholdt and become the new Colossal Titan, saving his life in the process. 
In Japanese, he is voiced by Marina Inoue, who also voices Momo Yaoyorozu in My Hero Academia, Yoko Littner in Gurren Lagann, and Kou Seiya from Sailor Moon: Cosmos. In English, he is voiced by Jessie James Grelle who voices Fumikage Tokoyami in My Hero Academia.
== Personality==
Even when he was a child, the naturally curious Armin had a deep fascination with the world beyond the Walls.
As a child, he found and studied an illegal book about the outside world that was owned by his paternal grandfather. He told Eren Yeager, his best friend, about the book and the information that was it contained. Armin was branded a heretic by other children for his unusual interest in the outside world, and was thus frequently picked on. Too timid to defend himself, Armin would often rely on his friends Eren and Mikasa to protect him from local bullies. This, coupled with his frail physique, was a source of much shame for Armin, leading him to have a very low opinion of himself, believing that he was a burden to others. Because of this, Armin has always been very eager to prove his worth. As a child, he hoped that one day he would be able to consider himself a true equal to his friends.
When Armin got older, he enrolled in military training and after graduating he joined the Survey Corps with Eren and Mikasa. He wanted, first, to try to make a good and meaningful impact on the world, and second, to realize his dream to see the outside world. His curiosity has remained a strong personality trait from when he was young, driving him to do whatever it takes to ensure humanity's triumph over the Titans. However, Armin continued to have low self-esteem during his training years and for a short while after graduation. During this time Armin considered himself to be useless due to his lack of physical strength and skill. However, soon after graduation, he came to learn that his mind is an equally valuable asset to the military, and that he can use his brain to help people. Consequently, Armin gradually gains confidence in himself and his abilities. Nonetheless, he can still be hard on himself at times. The fact that he is so willing to sacrifice himself to achieve a goal shows that he still does not value his own life as much as he should.
Armin is exceptionally loyal and selfless. He constantly worries for the safety of his friends. He is always prepared to throw himself into dangerous situations to save them, even offering to sacrifice himself for Mikasa. When he, Jean Kirstein, and Reiner Braun had to decide who would be left behind without a horse, Armin immediately offered himself without hesitation. When Jean was injured in battle, Armin rushed to his aid, placing himself in danger as well. Although he and Eren were determined to live their dream of seeing the outside world, Armin was content to give his life in order to defeat the Colossus Titan and to have his dream fulfilled through Eren. Armin is also very level-headed, keeping Eren and Mikasa under control whenever their emotions get the better of them. He has talked down a fight Eren started with a soldier, and restrained Mikasa from acting rashly during Eren's military trial.
Armin is a very analytical person. He likes to think deeply about situations and solve problems using his mind. These personality traits, in conjunction with his intelligence, good judgment, level-headedness, ability to plan ahead, and the ability to come up with creative ideas and think outside the box are what make him a great tactician. He is not an extrovert or loud person. When he was suddenly thrown into a leadership role that involved being in the spotlight, speaking in front of people and ordering people around constantly, he got quite anxious and momentarily froze up. Armin has shown great investment in humanity's future, and is always striving for and thinking about how he can change things for the betterment of mankind.
Armin's hard and cruel life has caused him to have certain beliefs about how the world works. Armin believes that in the cruel world in which they live in order to surpass monsters, accomplish goals or make a difference, one must be willing to sacrifice anything, even their humanity. Armin admires strong leaders such as Erwin Smith, Darius Zackly, Ian Dietrich, and Dot Pixis for their ability to sacrifice themselves and their humanity in order to achieve their goals. He believes that tactical decisions should be based on logic rather than emotions.
Even though Armin makes calculated decisions, he is also a very emotionally sensitive and empathetic person. Due to Armin's kind heart, he faces conflict in his mind with his belief that he has to force himself to throw away his humanity. For example, Armin killed a person to save Jean as it was the logical thing to do; however, he became very emotionally upset afterward. This, in conjunction with the fact that he is hard on himself whenever he does something wrong, means that he is yet to completely throw away his humanity. Armin's most consistent traits remain his kind heart and keen intuition, making him often concerned with the group's morality. 
Even when killing multiple Marleyan soldiers and civilians, Armin emerges from his Titan in tears. Nevertheless, Armin strongly believes that morality is relative and that there are no universal laws of good and evil. Therefore, he has a distaste for the terms 'good person' and 'bad person', since no one could be either good or bad to everyone. This makes him willing to concoct underhanded, morally questionable plans that shock some of his comrades. Notably, both Mikasa and Eren, his best friends, show no hint of surprise at this ability of his, with the latter even commenting that he had always known Armin was capable of it.

==Story==
Armin decides to join military training along with Mikasa and Eren, because after his parents and grandfather got killed, he couldn't sit around doing nothing. He was able to pass the basic aptitude test after some effort and tries to help Eren with it. Armin was considered weak in physical strength and graduated below the top ten. However, he was top of the class when it came to theoretical courses. Although his plans have saved Eren and Mikasa several times, he doesn't realize it and despises himself for being reliant on them.
Armin fears humanity's fate when he hears of the attack on Trost. He trembles in fear and was having problems in fixing his gear, when Eren tells him that not all was lost. Armin joins Eren's squad to guard the middle of Trost and departs with him to their prescribed location. On the way, Titans attack and eat up everyone in his squad except him. Armin supportively blamed himself for allowing Eren to sacrifice himself to the bearded Titan. Mikasa tells Armin that his strategies have always saved their lives and he should have more faith in himself.
In Trost's military headquarters, a number of Titans were attacking them and had took control of the supply depot. Armin devised a plan, wherein the soldiers would lower themselves via an elevator and lure the seven Titans towards them. As soon as they get close enough, everyone would shoot their eyes with firearms, momentarily blinding them and seven skilled soldiers, who would be hiding beforehand, would attack and kill those Titans from behind. The plan succeeded and everyone was able to refill their gas tanks to return alive.
After recovering Eren, he was detained by a group of soldiers and was going to be executed. Armin and Mikasa defend him, as he wakes up and is surprised. Eren plans to escape over the walls unless Armin was able to convince the soldiers regarding Eren's value to humanity. Eren tells him that his quick thinking had saved him and Mikasa before, as he was the one who went to Hannes when Shinganshina was being attacked. Armin, more confident than ever, walks over and tries convincing the soldiers about Eren's strategic and tactical importance in turning the tide of the battle in Trost. As a soldier, he passionately decides to die for this cause and makes a grand salute. Pixis notices his determination and passion and prevents their execution.
Now with a boost in self-confidence, he tells the senior strategists about a plan to retake Trost. He tells them that Eren could carry the boulder over to the hole while other soldiers could lure the Titans towards the walls. They proceed with the plan. Later, when Eren lost control and was knocked out, Armin goes running towards Eren and lands on his back. He remembers the position from where Eren had risen earlier, so stabs him a little askew so that it wouldn't be fatal, but would wake him up. He reminds Eren of his dream to go outside and his personal vendetta against the Titans. Eren, successfully motivated by Armin's effort, carries the boulder and plugs the breach.
After the two Titans, Sonny and Bean, were slain, Armin notices Annie in possession of Marco's Three Dimensional Maneuver Gear. He realizes that Annie might have been the one who killed the two Titans but decided not to believe his train of thoughts. After joining the Scouting Legion with Eren, Mikasa and the other graduates (excluding Annie Leonhardt), they went outside Wall Rose for the Scouting Legion's 57th expedition, when they were confronted by the sudden appearance of the Female Titan, seemingly knowledgeable about military formation. She attacked Armin while he was wearing his hood, under the impression that he was Eren. However, once it was removed, she realized she had the wrong subject and left him aside. Armin noticed a few things regarding the female Titan: she avoided killing Jean and him even though she had the chance, and it seemed as though Reiner had carved letters onto her palms, after which she directly charged towards the rear of the middle flank. Adding the knowledge that Annie had used Marco's gear during the checkup, Armin realized Annie was, indeed, the Female Titan.
Armin asks Annie for her help in hiding Eren because she was in the military police and they needed her to let them pass through Wall Shina without suspicion. Annie accepts and Armin explained that he wanted to take advantage of the geography there rather than use the 3DMG to bust through. As she was leading them to a hiding place, Annie refused to go inside to help them escape and asked him why he was looking at her with suspicion. Armin then took the time to ask her the reason she was in possession of Marco Bodt's 3DMG. He recognized it not too long ago because he and Marco would often do routine check-ups to make sure they were in pristine shape. Annie confessed that she found it after Marco died and that she used her own 3DMG to kill the two captured titans. She then asked him if he had already come to all those conclusions, why hadn't he taken action earlier. Armin reasoned that he didn't do so because he wished to believe that there was still something wrong with his train of thoughts. It was when Annie refused to kill him that things turned out the way they did.
Armin attempts to capture Annie by firing the signal from his flare gun letting the townspeople capture her. As the people tried to restrain her, she managed to injure herself with a sharp metal projection hidden in her father's ring. Noticing this, Mikasa grabs both Eren and Armin and takes them further underground as Annie in her titan form attempts to capture them. When Armin learns his plan had failed he attempted to start plan B, trying to encourage Eren to fight Annie. Eren tried to transform into his titan form, but he was unable to do it. It was only then Mikasa and Armin learned why, he was reluctant to fight Annie again because he still couldn't believe that Annie was indeed their enemy. And he didn't want to fight against one of his comrades. Having no other option, Armin tells Eren that he and Mikasa would go out through each of the two openings. Annie would go after one of them and Eren should utilize the opportunity to escape via the other opening. Realizing that his friends were in danger, Eren finally transforms into a Titan and fights Annie.
After Annie's capture, Armin tells Jean Kirschtein that Eren's summoning to the King were canceled and that Annie is the Female Titan. She's been detained underground after encasing herself in a crystal to avoid interrogation. Armin couldn't understand how the walls were built in the first place because there were no stones or bricks around. He hypothesizes that the titan's hardening capabilities were employed to build the walls. He believes it could explain how Annie was able to encase herself in a crystal. Armin's hypothesis was confirmed when the rock sample Lt. Hanji had picked up from Annie's body matched the crystal properties of the Walls. He and the others learn from Lt. Hanji that the only way they could repair the walls is if Eren can use his hardening abilities to help fix Wall Rose. Pastor Nick tells them about a girl in the Scouting Legion knowing more about what's going on and it's up to her to decide if she'll talk. Armin then recognized Christa because she was often seen with Ymir.
Once the Scouting Legion had rescued the others from the South Squad, Armin learns that Christa's real name is Historia and how heavily injured Ymir was during her fight with the titans. He immediately learns of Reiner and Berthold's secret correspondence with Annie. Like Mikasa, Armin was very angry to learn about their betrayal after overhearing the confession about them being responsible for Wall Maria being breached.
During the battle with Bertholdt and Reiner, Armin states that the Colossal has very slow movements and that they should exploit it. However, they were taken by surprise when he uses his vapors of heat to keep them off him. Realising that Berthold is just as desperate to stay alive, Lt. Hanji orders Armin and the other members of the Scouting Legion to go after Reiner. Armin discovers a weak link to Reiner's line of defense when he saw his armor break. Giving Mikasa and extra set of blades, he tells her to go after the back of his knee caps. Soon Berthold took everyone by surprise by falling off the wall.
With Eren and Ymir now kidnapped by Bertholdt and Reiner, he focuses his attention in helping Mikasa and the others until help arrives. Armin tells her the news that she had been dreading and wrapping her lower face in the scarf, she cried. She asks him why he always has to leave them behind when trouble rises. As Armin tries to console her, Hannes arrives to give out rations to everyone in the Scouting Legion. He tells them that Eren has always been like that, running into fights despite knowing the odd are against him. Hannes even mentions that although he won't admit it, he always knew Armin and Mikasa were there to help him out. Reinvigorated and determined to rescue both Eren and Ymir, he takes his stance with the Scouting Legion, Wall Guards and Military Police. Armin wants Historia to stay within the walls, but she refuses and decides to join them.
Armin and the others reach the Forest of Giant Trees where Reiner and Bertholdt were resting. While inside the forest on their 3D gears, they notice Ymir's Titan form. Armin suspiciously notices that she was surveying everyone and wasn't responding to anyone. Her suspicions were confirmed when she captures Christa and escapes. He realizes that Ymir was definitely working against them.
==Abilities==
Being one of the physically weakest soldiers there are, he is rarely assigned to the frontlines and rarely seen using his 3DMG for fights. His main strength, however, lies within his intelligence - an innate abilities in deduction and forming strategies, be it in a war room or on the fly, as well as an eye for obscure details, making him a remarkable field tactician, a trait that only he displays among the current recruits. His strategies helped save his fellow soldiers numerous times and more remarkably, he is the key person who deduced the identities of all hostile titan shifters among the current recruits. He wasn't able to display his remarkable intelligence earlier due to a serious lack of confidence in himself. After acknowledging that he is actually far more useful than he thought he is, his genius as a tactician began to show and thus far, even commanders are shown to take his opinions in matters relating to titans seriously.
