Erik (エリック Erikku),Fairy Tail Manga: Chapter 365, Page 18 formerly known by the code name Cobra (コブラ Kobura), is a former member of the now-disbanded Oración Seis,Fairy Tail Manga: Chapter 130, Page 20 a Dark Guild composed of six powerful Mages. He, along with the other Oración Seis members, sought to find Nirvana, a destructive Magic that was sealed long ago.Fairy Tail Manga: Chapter 131, Pages 18-20 Erik was among the few remaining members who formed the Reborn Oración Seis, and later joined Crime Sorcière per Jellal's request to help him take down Zeref.Fairy Tail Manga: Chapter 369, Pages 13-14 In the year X793, he became the boyfriend of KinanaFairy Tail Manga: Chapter 545, Page 26 and later on her fiance.Fairy Tail: 100 Years Quest Manga: Chapter 154, Page 4
==Appearance==
thumb|left|200px|Erik's full appearance
Erik is a slim man of average height with dark tan skin and spiky, upward-styled maroon hair; aside from a tuft covering his forehead and two bangs framing his face and purple slit-pupil eyes. He’s noted to have snake-like features, with slanted eyes similar to Natsu’s,Fairy Tail Anime: Episode 53 a rather flat nose, and prominent canine teeth. He also sports a simple circular earring on his ears. Being an artificial Dragon Slayer, when Erik makes use of his Dragon Slayer Magic, the tops of his hands and forearms become covered in crimson Dragon scales, while the bottoms are milky and smooth. His hands also turn into sharp, pointed, claws.Fairy Tail Manga: Chapter 149, Page 21
Erik's outfit consists of an elaborate whitish coat with purple inner lining and cuffs intricately decorated by silver-colored motifs, and many studs lined up the chest, the high collar and the sleeves, which have armbands seemingly made of metal around them above Erik's elbows. Below it, Erik wears a dark shirt, and he also sports a pair of crimson leather pants held up by a studded belt, with more similar belts circling diagonally the upper parts of his legs, and simple brown shoes.Fairy Tail Manga: Chapter 149, Page 3
Erik's attire received some changes in the anime. His coat doesn't have the intricate motifs on the purple parts nor any visible studs, and is given light bluish edges and modified armbands, being dark and each sporting a large, red gem.Fairy Tail Anime: Episode 51 In X791, Erik has a scar across his right eye (a result of the sacrifice he made to attain new powers) and his ears are also noticeably pointed; in addition, he no longer wears the earring on his ears.Fairy Tail Anime: Episode 140Fairy Tail Manga: Chapter 329, Page 20
==Personality==
Like the other members of the Oración Seis, Erik is confident and enjoys seeing his opponents suffer.Fairy Tail Manga: Chapter 134, Page 16 Erik believes that Second Generation Dragon Slayers are superior to First Generation Dragon Slayers, and even finds their existence questionable, as Dragons are believed to be extinct, and therefore finds it ridiculous that people such as Natsu were taught their Magic by nonexistent beings.Fairy Tail Manga: Chapter 150, Pages 8-9 He also seems to be quite easy-going, and was able to laugh at a joke during a battle.Fairy Tail Manga: Chapter 149, Pages 16-17
Erik harbors great affection towards his snake Cubellios, considering her to be his greatest friend, and being willing to dedicate his prayer to hear her voice, which in itself is impossible, even for someone like Erik, who has exceptional hearing.Fairy Tail Anime: Episode 62 He later realizes that Kinana is Cubellios when they reunite.
In X791, Erik seems to have become more reserved: for he is much quieter and serious, no longer taking enjoyment in beating his opponents, though his personality has also taken an angrier turn, becoming hostile easily. He frequently belittles Erza Scarlet and the Fairy Tail Guild for their faith in friendship. He also experiences inner turmoil regarding the Reborn Oración Seis, and how much they had to give up; he believes that Fairy Tail is undeserving. His aggression stems losing Cubellios years prior.Fairy Tail Anime: Episode 143 It is not until he is defeated by Erza and he sees Kinana again that Erik forgoes his forsaking of friendship. Upon reuniting after 7 years, which Erik realizes Kinana is Cubellios and willing reveals his true name, something that is forbidden in his guild. However, he pretended to not know Kinana to protect her from being arrested for associating with him as he surrenders to the council. Despite being arrested, Erik finds solace that he's finally able to hear her voice due to her human form, thus finally achieving his prayer and letting go of his aggression and seemingly returning to his old personality, albeit less cruel.Fairy Tail Anime: Episode 150
Aside from Kinana whom he shares a strong bond with, Erik seems to be quite loyal to his guildmates that originated from the Tower of Heaven as slaves, like him. Erik negotiates with Doranbolt for their release and is unwilling to spill until all of them are guaranteed their freedom, proving that he does care about his guildmates (aside from Brain).Fairy Tail Manga: Chapter 356, Page 29 After hearing that Brain only views them as pawns, he tells Midnight and he kills Brain as retribution. Midnight trusts Erik's judgement; a proof of their own bond.Fairy Tail Manga: Chapter 364, Pages 23-24 They, as a whole, join Jellal's Independent Guild, choosing to stay together instead of going their separate ways, with the goal to stop Zeref from spreading his evil.Fairy Tail Manga: Chapter 416, Page 19
Despite Kinana's request to not read the thoughts of others, Erik still audaciously listens to their thoughts in secret, hoping to learn anything embarrassing, especially about Natsu from the Fairy Tail guild. However, at times he'll hear things he wished he hadn't. While Erik isn't normally intimidated by anyone, it's not until he meets Warren Rocko, a telepath who can read his thoughts and reveal the parts of Kinana he likes, causing him genuine fear for having his embarrassing thoughts exposed, more so than Laxus and Erza, discouraging him from joining the guild despite Kinana's suggestion to apply.Fairy Tail: 100 Years Quest Manga: Chapter 154, Pages 8-20
As mentioned by Sorano, he can be very shy, something at which he scoffs the mere notion. Also, as a Dragon Slayer, Erik suffers from motion sickness when riding on any form of transportation.Fairy Tail Manga: Chapter 486, Page 6
==History==
Jellal enslaved Erik as a child until Brain arrived at the Tower of Heaven and took Erik and four other enslaved children to become members of his own guild, all with Jellal's permission. Erik soon became a member of the Oración Seis, one of the three most powerful Dark Guilds, and, along with his guildmates, began to seek out the lost, destructive Magic, Nirvana.
At some point before seeking Nirvana, Erik implanted a Dragon Lacrima into his own body, which thereby resulted in him becoming the Poison Dragon Slayer.Monthly Fairy Tail: Volume 7
==Synopsis==
===Battle of Fairy Tail arc===
Within a palace-like building, Cobra remarks that he can hear the sound of the light crumbling.Fairy Tail Manga: Chapter 130, Pages 19-20
===Oración Seis arc===
Cobra, along with the other members of the Oración Seis, attacks the Allied Forces; he engages Erza Scarlet in combat. The two battle on equal ground, that is, until Racer and Hoteye join the fray, turning their conflict into a three-on-one battle. Using the openings granted by his comrades, Cobra orders Cubellios to bite Erza's arm, poisoning the S-Class Mage. As Erza reels from the assault, Cobra informs her that the poison isn't fast-acting and will kill her slowly.Fairy Tail Manga: Chapter 134, Pages 9-18
Cobra, on Brain's orders, follows Jellal, as they believe that he is trying to steal Nirvana from them. Cobra eventually succeeds in finding Jellal and bares witness to Nirvana's activation.Fairy Tail Manga: Chapter 141, Pages 9-11 Distracted, Cobra continues watching Nirvana activate, allowing Erza to arrive at the scene unnoticed. Seeing her, Cobra becomes shocked, having believed her to have died at the hands of Cubellios' poison.Fairy Tail Manga: Chapter 145, Pages 17-19
Cobra then moves to confront Jellal and proceeds to learn that Jellal has placed a Square of Self-Destruction on Nirvana. After failing to undo the spell, Cobra tries to regain Jellal as an ally, but becomes horrified when he sees that Jellal has placed a Square of Self-Destruction on himself as well.Fairy Tail Manga: Chapter 146, Pages 15-21 Luckily, however, much to Cobra's pleasure, Brain arrives and dispels the Square of Self-Destruction before ultimately activating Nirvana's Second Stage. However, as the great Magic activates, the Fairy Tail delegates slowly make their way up Nirvana's legs, unbeknownst to Brain and Cobra.Fairy Tail Manga: Chapter 147, Pages 5-17 Natsu Dragneel, carried by Happy, manages to make his way to the center of Nirvana and attack Brain but is intercepted by Cobra, who is riding his now-winged serpent, Cubellios. Now, confronting one another in midair, Cobra momentarily overwhelms Natsu due to his ability to hear the Fire Dragon Slayer's movements. However, after hearing Natsu's thoughts, Cobra maliciously chuckles, stating that he'll gladly "play" with Natsu.Fairy Tail Manga: Chapter 148, Pages 8-17
Laughing over the top of them, Cobra heeds Brain's order to kill Natsu and Happy, gleefully stating that they'd make a wonderful snack for Cubellios. Charging at them, Cobra and Cubellios repeatedly knock Natsu and Happy away; Cobra repeats multiple times that Natsu's efforts are in vain, as he can hear him.Fairy Tail Manga: Chapter 149, Pages 2-6 Cobra then proceeds to dodge Natsu's blind strikes, stating that, contrary to Happy's belief that his Magic allows him to solely read movements, his Magic allows him to hear the voices of others' hearts. Cobra then pauses before laughing at a joke Natsu formulated inside his head, confirming his just-prior statement. Right after, Cobra repeats the battle strategy Happy is conveying to Natsu, once more telling them that he can hear their thought process and that they have no hope of defeating him. Much to Natsu's fury, Cobra counts off the number of other strategies Natsu has formulated inside his head, considering some impressive but mocking him as he does so. Natsu then goes on the offensive, charging at Cobra; Cobra dodges Natsu's first two strikes, but is nicked by third and taken aback. He is then repeatedly hit by Natsu, completely shocked at Natsu's lack of thought. Blocking Natsu's final punch, Cobra praises Natsu, telling him that he's never encountered someone such as him and that cheap tricks won't work. As his coat sleeves begin to disintegrate, Cobra inflicts damage to Natsu's caught hand and, after activating his proper Magic, reveals himself to be the Poison Dragon Slayer.Fairy Tail Manga: Chapter 149, Pages 17-21
Cobra then goes on the offensive, personally swiping at Natsu with his claws and kicking him away with poison-enhanced kicks, destroying Natsu's flesh with each strike. Cobra then states as the he is the Poison Dragon Slayer, his very touch destroys everything, dodging every one of Natsu's attacks and countering with one of his own. Calling out his snake's name, Cubellios releases a large quantity of poisonous mist from her mouth, which Cobra then proceeds to eat. The Dark Mage then attacks Natsu and Happy with his Poison Dragon's Roar, infecting them with a neurotoxin that degrades their movement and eventually kills them. Cobra is then interrupted by Natsu as he tells them that their victory was sealed when his Roar struck them, dodging a kick meant for him. Cobra then praises Natsu once more, this time, however, for moving as well as he is after being subjected to his viral toxins, calling the Fairy Tail Mage, an "Old-Style Dragon Slayer", visibly angering Natsu. Raising his arms wide, Cobra explains that he implanted Dragon Lacrima into his body, thereby allowing him to become a Dragon Slayer; he counts himself among the new generation of Dragon Slayers. Claiming Natsu's Magic to be more questionable than his as Dragons are extinct, Cobra charges at the duo once more, denying Natsu's claim that Igneel ever existed.Fairy Tail Manga: Chapter 150, Pages 2-9
Cobra throws Natsu into the air with his Poison Dragon's Twin Fang, demanding that Natsu dies, as the poison has completely spread throughout his body. Cobra then hears Natsu and Happy conversing; Natsu demands that Happy drop Natsu right on top of Cobra so that he may deliver a point-blank Fire Dragon's Roar. Cobra then ridicules Natsu, stating that his random physical attacks did more harm than this new strike will bring. Seeing that Natsu is opting for a wide-range assault, Cobra catapults himself over Natsu. Now above the Fire Dragon Slayer, Cobra moves to crush Natsu's skull with his claws, but is heavily affected by Natsu's scream, screaming in agony as his ears reverberate with pain. Cobra then falls from the sky and hits the ground, unconscious, as Cubellios rests beside him.Fairy Tail Manga: Chapter 150, Pages 11-19

Cobra, however, immediately returns to his feet, stating that as a member of the Oración Seis, he must defeat Natsu for the sake of his pride. Cobra then covers his fist in poison and motions to attack Natsu, stating for the "Old-Style" Dragon Slayer to die. However, much to his and Natsu's shock, Cobra is shot by Brain, the magical blast going through the Poison Dragon Slayer's shoulder. Confused, Cobra asks Brain what he did wrong, to which Brain replies that Cobra needs to rest and that he did well. Brain, however, blatantly thinks, intending for Cobra to hear that he is trash for losing to a "common guild" such as Fairy Tail, stating that he doesn't need the Oración Seis if they are that weak. Cobra then falls to the ground, crying, stating that he only wished to hear the voice of his best and only friend: Cubellios. Later he is arrested alongside his Guildmates.Fairy Tail Manga: Chapter 151, Pages 3-7
===Key of the Starry Sky arc===
When the members of Fairy Tail gather in front of Byro Cracy with the clock parts, the Reborn Oración Seis are warped in front of the Fairy Tail Members and the Legion Corps; Cobra appears with Angel, Jackpot, Midnight, Erigor and Racer.Fairy Tail Anime: Episode 139
thumb|left|200px|Cobra releasing his Magic Power
Team Natsu is shocked to see them, the Reborn Oración Seis, appear with the Infinity Clock before their own eyes. Cobra is silent during this encounter, merely raising his arm with the others to mark the Infinity Clock with their Guild Mark. He later says that he can hear the hearts of the Fairy Tail Mages despairing. Afterwards, Midnight orders Cobra and Racer to both dispose of Fairy Tail as punishment for humiliating them 7 years prior Cobra confronts Wendy and Carla and asks, after greeting them rather politely, if they can answer his question; he intently listens to their hearts to see the answer before realizing, however, that they do not know it, annoying Cobra. He releases a great surge of Magic Power, immobilizing the two. Still rather angered, an annoyed Cobra responds to a charging Natsu Dragneel with Sound Wall, causing great destruction within the area. As the Reborn Oración Seis slowly defeat those present, Cobra returns to his guildmates and asks if they can leave. After Angel summons Barakiel, the group disappears with the Infinity Clock.
In an unidentified location, with his guildmates and the Infinity Clock, Cobra talks about how they still need a certain something to bring the world's destruction. He then listens as Midnight reminds them of their goal, and how they'll be using the Infinity Clock to achieve it. As night falls, the Reborn Oración Seis relocate near a small town, where Cobra informs the others about how there are four churches and that the guards protecting them are unaware of their presence, as well as the fact one of their priests was recently relocated. He then says that they should go and darts off. They attack the church and the guards protecting it, though for Cobra's focus, during the attack, lies more in investigating the area. He hears a person underground using Concealment Magic and, together with Angel, completely destroys the building. Angel speaks out to him and Cobra states that on their "tasteless" path, he will find and kill "her" so that he can gain the power to overcome the pain and misery he suffered for the last seven years.Fairy Tail Anime: Episode 141
thumb|left|200px|Cobra vs. Erza: Rematch
Sometime after this event, he encounters three members of Fairy Tail near a mountain passage: Erza Scarlet, Evergreen and Max Alors. He battles against them and easily takes out the latter two Mages before turning his attention to Erza. Throughout his fight with them all, Cobra speaks about Cubellios; remembering how he lost her to Fairy Tail rages him, causing him to fight rather ruthlessly.
Cobra continues his fight against the three Fairy Tail Mages but constantly reminds them that their efforts are futile, as he can hear them; he attempts to strike Erza, but Max jumps between them, taking the blow meant for his comrade, prompting Cobra to scoff and states how their friendship sickens him. He then softly adds that with Cubellios gone, he has no friends. When asked asked about it by Erza, Cobra says that nothing can help him overcome his intense heartache. He remains silent after she responds with how everyone has a pain in their heart. However, he overhears Fiore Guards talking in the distance and, remembering his goal, flees the battle.
Later inside the Infinity Clock, Cobra, along with Angel, Midnight and Klodoa, finds out that Racer has been defeated. Midnight then commands Cobra and Angel to stop Fairy Tail, as Racer was unable.Fairy Tail Anime: Episode 146
Cobra waits for the Fairy Tail Mages who want to save Lucy inside a room of the Infinity Castle and, once they appear, he attacks Erza with his Magic. Although Natsu says that he wants to fight him, Cobra challenges Erza to a fight instead, and she accepts. Soon, however, Sugarboy appears and interrupts them, saying that Byro told him to get rid of Fairy Tail. Cobra, on the other hand, shows no interest in Sugarboy and quickly gets rid of Legionnaire with his Sound Magic before resuming his fight with Erza.Fairy Tail Anime: Episode 147
Cobra's Magic remains effective against her as they continue their battle. Throughout their fight, however, Cobra becomes increasingly annoyed at Erza's words, describing her them as "grating", and pushes their fight to outside the Clock. Out in the open, Erza asks Cobra why he wants to bring despair people the same despair he felt as a Tower of Heaven slave. He responds by saying that he could care less, though adds that he has no friends, while she and various other people are surrounded by them; Erza mocks him for his envy and the two resume their conflict.Fairy Tail Anime: Episode 148
As they fight, Cobra senses Erza's need to have him defeated to free Lucy and tells her that such a thing is impossible, as he has lost something in order to gain his powers, and therefore bears weight far greater than hers, strengthening him. As Erza scolds him for using such power for evil, Cobra responds by stating that if he didn't, he could never look Cubellios in the face again; Cobra prepares to use his Poison Dragon's Roar only to have it cancelled by the weapon Erza was given by the Archaeological Society. As Erza starts to break the chains that connect the Infinity Clock to the ground, Cobra continuously tries to hinder her movements. However, he quickly loses his concentration in the battle when he hears Kinana's thoughts from the ground below, recognizing them as belonging to his former serpentine companion. His pause gives Erza the chance she needs, and with one giant swing of her weapon, Cobra falls from the Clock, defeated.Fairy Tail Anime: Episode 149
Horribly wounded and lying on the ground, Cobra silently curses Erza before hearing somebody approaching. Calling out to them, he is shocked to see a young girl with purple hair who immediately runs to his aid. As she holds him and he tries to get out of her reach, Kinana asks him if he is the one who has been calling out to her, and Cobra realizes with a jolt that she is the person whose thoughts he has been hearing and trying to communicate with. As Kinana asks about his eye, Cobra reveals that he sacrificed it to attain greater power. When she asks, Cobra reveals his real name to her: Erik. 
Before they can talk any more, however, Doranbolt and Lahar teleport into the area, recognizing Cobra and asking him to come with them, as they have already arrested the remainder of the Reborn Oración Seis. As Kinana begins to protest, Cobra hears both the Councilmen's thoughts, realizing that Kinana may also be arrested, as she is with him. Denying that he and her are allied, Cobra stands and walks toward Lahar and Doranbolt, giving himself up and stating that he has never met Kinana in his life. Secretly happy that he has finally found his beloved Cubellios again, Cobra leaves, arrested once more. 
===Grand Magic Games arc===
During the Dragons' invasion in Crocus, Doranbolt sets Cobra free in order for him to be able to aid the other six Dragon Slayers in defeating the seven Dragons that were brought from the past; Cobra says he can hear the Dragons attacking the town, and that he can also hear Natsu's words.Fairy Tail Manga: Chapter 329, Pages 19-20
Wasting no time, Cobra sets out and brutally strikes the Rock Dragon that was attacking Blue Pegasus, saving the guild. Ecstatic at being able to fight, Cobra tells Ichiya to get out of his way, much to the latter's displeasure; the others, particularly Hibiki Lates, express their shock at seeing the former Dark Mage on the loose.Fairy Tail Manga: Chapter 330, Pages 10-12 Now moderately injured, Cobra gleefully continues his fight with the Dragon made of rock.Fairy Tail Manga: Chapter 332, Page 15
However, Cobra's fight soon turns one-sided, as the Dragon further injures him without him being able to fight back, while the King explains that this is what used to be called the Dragon King Festival in the ancient times.Fairy Tail Manga: Chapter 333, Page 11 This changes when, unbeknownst to Cobra, Ultear Milkovich uses Last Ages in order to turn back the entire planet's time by one full minute.Fairy Tail Manga: Chapter 335, Pages 9-13 Now able to fully predict his opponent's moves for the next one minute, Cobra smiles, as he can now begin his counterattack.Fairy Tail Manga: Chapter 335, Page 20
It is not long after that, through the efforts of several Dragon Slayer Mages in the city, the Dragons are removed from the timeline by the destruction of the Eclipse Gate. With his opponent gone, Cobra sits down to observe the aftermath and laments his inability to defeat a Dragon, commenting on it, leaving a bad taste in his mouth.Fairy Tail Manga: Chapter 337, Page 12
Shortly after the battle is over, Cobra returns to Rune Knights, allowing himself to be arrested again. As he pities himself over being unable to defeat even a single Dragon, Lahar and Doranbolt note that despite being an outlaw, he keeps his promises. Cobra states that being outside felt good, as he could hear many voices, including that of Cubellios. With a wicked expression on his face, he then notes to himself that he is back only to save the rest of the Oración Seis. Doranbolt questions the voices that Cobra could hear, with the latter telling him that the "gates of the netherworld" are about to open, referring to Tartaros. He also tells Doranbolt not to fiddle with his memories until that happens, leaving Doranbolt visibly surprised.Fairy Tail Manga: Chapter 339, Pages 8-9
===Tartaros arc===
After the attack on the Magic Council by the Tartaros member known as Jackal, Cobra is approached by the surviving Doranbolt, who questions if he heard what happened on the floor above; leading Cobra to grin slightly as he reminds him of the cell's ability to prevent him from using Magic, claiming that he was able to hear the ruckus with his ears alone. Wasting no time, Cobra is ordered by Doranbolt to confess what he knows about Tartaros, but Cobra demands the release of the Oración Seis in exchange for that information. However, Doranbolt admits that he has no authority to do so and surprises Cobra by revealing that everyone with such authority is already dead; moreover, even after being threatened to reveal what he knows when the latter holds a knife to his neck, Cobra still insists on the condition. The Dragon Slayer, however, decides to reveal one thing: all members of Tartaros are Demons from the Books of Zeref, with their Master, E.N.D., being the strongest one.Fairy Tail Manga: Chapter 356, Pages 24-30 
Later, having given Doranbolt information about Tartaros' goal of using Face, it is shown that he has gotten the release of the rest of the Oración Seis. As Brain starts to congratulate Cobra, Cobra strikes him down, revealing Brain's true feelings towards them, asking Midnight if he has any problem, to which he states he does not. As the rest of the Oración Seis discuss what to do next, Cobra stops them, and tells them that they have company; in front of them appear Jellal Fernandes and Meredy.Fairy Tail Manga: Chapter 364, Pages 17-23 Hearing Jellal state that he alone is enough for the five of them, Cobra realizes that he came at Doranbolt's behest. However, as Jellal stands in the way of their true freedom, Cobra threatens Jellal with his life; Hoteye tells his friends that he doesn't want to fight and that he'll submit to Jellal, earning him a remark from Cobra, though their complaints are quelled by Midnight. Heading Jellal's baiting, Cobra attacks Jellal in tandem with Racer, though his strike is blocked and he is thrown into his comrade. Seeing Jellal overpower Angel as well, Cobra looks at his opponent with unease.Fairy Tail Manga: Chapter 365, Pages 15-21 A short while later, Cobra manages to gain the upper hand on Jellal, forcing him to defend against one of his clawed strikes and sending him to be at Racer's mercy.Fairy Tail Manga: Chapter 365, Page 25
Continuing the fight, Cobra refuses to let up against Jellal, intent on securing freedom for himself and his allies. However, Jellal speaks out against this, telling them that he will free them. Surprised as Jellal hits Racer and tells them their freedom is a lie, Cobra is then taken out by Jellal, who states that it will remain so as long as they remain taken by darkness.Fairy Tail Manga: Chapter 367, Pages 9-13 Off-put by Jellal's statement that he will free them by defeating them, Cobra is then shocked as Zero suddenly awakens and strikes Jellal, not having realized he was still alive.Fairy Tail Manga: Chapter 368, Pages 15-16 However, Cobra is even more shocked to witness Jellal's escape from Midnight's illusion. Surrounded by Magic seals, he can only ponder the time it took Jellal to draw the circles—subsequently attacked alongside the other Oración Seis Mages by the latter's Grand Chariot. Shortly afterwards, Cobra falls to his defeat when Jellal employs his True Heavenly Body Magic. As the imposing man approaches the group, Cobra is left in pure awe when Jellal invites them to join his guild, knowing that they share a common enemy: Zeref.Fairy Tail Manga: Chapter 369, Pages 1-14
After the battle with Jellal, Erik and the other members are seen following the Crime Sorcière Mages, with the Dragon Slayer complaining the walk is tiring. Later as the Mages rest, Erik reprimands Sawyer for his continuous talk, with the Dark Mage being indecisive of his option of following Jellal. He then comments on the screams of people he's hearing, wanting to follow Jellal to confirm what he's hearing.Fairy Tail Anime: Episode 245
A while later, Erik and the other Demon Generals convene at deserted village. Sawyer goes on about why they should lean on Jellal's motives, with Erik simply dissuading from the question. He chuckles, hearing a voice with him pointing out it is one of the Seven Kin of Purgatory's Rustyrose, who is surprised that Dark Mages are alive. He leaves after encountering Meredy but is stopped when Erik admits he's interested in what he has to say, stating he can hear the fear in his voice. The Dark Mages then surround him as they force him to him to talk of the events that he encountered while at Tartaros. The latter talks of his encounters with one of the Nine Demon Gates; Erik giving him praise for barging into Tartaros. He later leaves after telling the Mages of a terror he felt when in the midst of discussions, with Erik stating that doesn't have anything to to do with the Oración Seis. Jellal appears as he declares they are going to Tartaros to prevent the Demons from accomplishing their goal, but Macbeth declines stating they won't break the pact between the Balam Alliance, with Jellal continuing anyway, mentioning that they'll meet again one day.Fairy Tail Anime: Episode 246
Erik and the other Oración Seis members are seen walking in wasteland, as Jellal describes Erik's prayer to Meredy of wanting to have a friend to tell his vast story to. Erik shrugs after overhearing the conversation, with Sorano wittingly stating that he is very shy, garnering criticism from the Dragon Slayer. Later the Mages save Jellal from Rustyrose's attack; Erik removing his bandages while admitting that they don't have anywhere else to go, with all of them agreeing to follow the former and take down Zeref.
Along their journey to Magnolia, Erik and the others follow Jellal in a hurry amidst noticing the Dragons destroying the Faces.Fairy Tail Anime: Episode 263
Note: End of anime only section.
As Face and Tartaros are brought to an end with the help of the Dragons, Erik joins Jellal and Meredy in their journey to bring down Zeref. He, along with the rest of Crime Sorcière, pays a visit to Magnolia, where Jellal provides Erza some support to continue on fighting—the scene prompting him to question Jellal's words.Fairy Tail Manga: Chapter 416, Pages 22-23 
===Alvarez arc===
Erik and his comrades arrive in the north, at Zonia, to assist in the war against the Alvarez Empire; upon hearing his comrades voice their own minds about the current state of affairs, Erik expresses an immediate desire to be let out of the Olympia, as he is experiencing extreme motion sickness. Before he and his comrades can do anything, however, Erik is caught in the light of Irene Belserion's Universe OneFairy Tail Manga: Chapter 489, Page 17 and is warped to a new location.Fairy Tail Manga: Chapter 490, Page 13
Erik eventually makes his way to the Fairy Tail Guild's new location and engages in battle with August of the Spriggan 12, alongside the other members of Crime Sorcière, bar Meredy and Sorano. August easily overpowers the group of five; Erik hears Jellal's defeatist thoughts and reasons that even if August is stronger than them, he can still hear what he's going to do. He goes to attack August, but August reveals that he, too, can use Sound Magic and listen in on his enemy's next action, resulting in Erik being easily swept aside. His other comrades then launch their own attacks, but Erik is ultimately caught up in August's use of Reflector to counter Macbeth's own;Fairy Tail Manga: Chapter 507, Pages 12-16 Erik and the others are then swiftly defeated,Fairy Tail Manga: Chapter 508, Page 13Fairy Tail Manga: Chapter 509, Page 2 and he remains unconscious for quite some time due to his injuries.Fairy Tail Manga: Chapter 514, Page 15
Much later, Erik is teleported by Acnologia who absorbed the Time Magic in the Space Between Time and used it to send all the Dragon Slayer to his world.Fairy Tail Manga: Chapter 539, Page 16 There, Erik is seen trapped in a crystal pillar by the Dragon King along with his fellow Dragon Slayers due to Acnologia needing them to stabilize his spiritual body and his new Magic. Erik is later freed of his imprisonment due to hearing the voices of those waiting for him in the real world as he remarks on the other Dragon Slayers hearing the voices as well. He joins his fellows in confronting Acnologia with the intention of slaying him once and for all.Fairy Tail Manga: Chapter 540 Page 17-19
===True Dragon King Festival arc=== 
==Magic and Abilities==
Poison Dragon Slayer Magic (毒の滅竜魔法 Doku no Metsuryū Mahō): By having a Dragon Lacrima implanted into his body, Erik obtained the ability to use this Magic. It grants him the power to produce poison from his body and to consume the one produced from external sources to heal and strengthen himself, which, as a result, grants him immunity from poison. The poison that he produces from his skin is so corrosive that it is said to be able to decay all that it touches, but can also act after a given amount of time: Erik stated that its effects are first visible in a progressive weakening of the victim's body, which then results in death.Fairy Tail Manga: Chapter 150, Page 3
*Poison Dragon's Twin Fang (毒竜双牙 Dokuryū Sōga): Erik moves his arms forward in a cross, forming a very large amount of poison in two massive waves shaped like fangs, which he uses to attack his opponents with great blunt force.Fairy Tail Manga: Chapter 150, Page 10 In the anime, this spell was portrayed differently, with the generated poison being split in many elongated, snake-shaped masses, which all move towards the opponent at once.Fairy Tail Anime: Episode 61
*Poison Dragon's Roar (毒竜の咆哮 Dokuryū no Hōkō): Erik's exclusive Dragon's Roar, incorporating the element of poison. Erik quickly gathers and releases poison from his mouth in the form of deadly, poisonous stream that, when it makes contact with the target, injects a lethal virus into their body that slowly weakens them and restricts their movement before ultimately killing them.Fairy Tail Manga: Chapter 150, Pages 5-7
*Poison Dragon's Fang Thrust: Erik generates a wave of poison, shaped like a large-fanged snake head, and sends it towards the target, stopping their incoming attacks by having the wave "bite" them.
*Poison Dragon's Spiral Jaw: Erik jumps in the air and, when he is upside down, gathers poison on his legs and kicks the opponent while rotating. This spell is highly reminiscent of the Dragon's Claw Spells employed by several other Dragon Slayers.
*Poison Dragon's Scales: Erik swings his arm, generating a very large number of scale-shaped masses of poison, which are rapidly sent flying at the target in consecutive reprises.
*Poison Dragon's Guard: Erik moves his arms forward in a cross, creating a large shield of poison that defends him from the enemy's attacks, and, at the same time, gives him the opportunity to counter without fear of being intercepted. (Unnamed)
*Poison Dragon's Twin Wings (毒竜双翼 Dokuryū Sōyoku): Erik attacks with a poisonous open-hand,Fairy Tail Manga: Chapter 150, Pages 2-3 striking with his fingertipsFairy Tail Manga: Chapter 150, Pages 3-4 from which poison mist trails.

Hearing Magic (聴く魔法 Kiku Mahō): Erik has the uncanny magical ability to hear a person's very soul, allowing him to tell if they are scared, what are they going to do next, and even allow him to hear their thoughts, thus enhancing his already perfect Dragon hearing. This ability is so accurate that it was actually confused as mind reading. With it, Erik was able to foresee all of the attacks performed against him and react accordingly, evading them without effort. His use of this Magic is so great that he was still able to counter each of Natsu's moves even when he tried to hide his thoughts. Though this only seems to work when the person's "voice" he is listening to is thinking, or has memories.Fairy Tail Manga: Chapter 146, Page 15 If this happens, Erik can focus his hearing on their movement and muscles contracting to read their attacks.Fairy Tail Manga: Chapter 150, Page 8 The Magic can also act as a double edged sword, as high pitched noises, such as Natsu's scream, can affect him greatly.Fairy Tail Manga: Chapter 150, Pages 13-19
Sound Magic: Erik gained the ability to use this type of Magic by sacrificing his right eyesight. He is shown to be able to use it offensively by emitting strong sound waves from absorbing and reverbing the sounds he hears. This Magic works to cover up Erik's weakness, repelling any sounds that may be too sensitive for his ears.
*Sound Wall: Erik manipulates the sound in his immediate vicinity into a wall of pure pressure, which simultaneously protects him and destroys portions of the surrounding area. This is done by absorbing a nearby sound, amplifies it and fires it out through the air in a large omnidirectional echo.
*Sound Palm: Through touch, Erik transmits a very powerful sound wave from his palm to the target's body, sending them flying.
Dragonization (竜化 Ryūka): Erik is capable of willingly dragonizing his arms into that of a Poison Dragon. Sprouting purple scales over his skin with white colored flesh on his palms and underarms as well as forming sharp clawed nails.Fairy Tail Manga: Chapter 149, Pages 20-21
*Scales: Erik’s scales act as dermal armor, increasing his resilience and durability.
*Enhanced Strength: Erik’s strength is further augmented, typically transforming his arms whenever he attacks with his Dragon Slayer Magic.
Anti-Link: Through the use of a magical , Erik uses this Magic to dispel an Organic Link given to or inherited by a person, as well as "removing" their Magic.Fairy Tail Anime: Episode 144
Enhanced Hearing: Erik has been shown to possess extremely fine hearing, being able to hear the explosion of the Magic Council Headquarters while deep in prison under the restraints of the Magic Sealing Stones. He was also able to clearly hear the conversation between Jellal and Meredy across a great distance.
Enhanced Durability: Erik has proven himself to be a very durable fighter; he has been seen enduring a barrage of powerful melee strikes from Natsu, enhanced by his Fire Dragon Slayer Magic, without receiving major injuries and continuing the battle afterwards as if nothing had happened. He also survived a fall of several meters which saw him coming crashing down to the ground,Fairy Tail Manga: Chapter 150, Page 19 and stood back on his feet moments after.Fairy Tail Manga: Chapter 151, Pages 3-4
Enhanced Strength: Erik has displayed a high degree of strength; he is shown to be capable of effortlessly sending Natsu flying several meters away with seemingly casual attacks on two different occasions, the first with a simple slap,Fairy Tail Manga: Chapter 148, Page 14 and the second with a knee.Fairy Tail Manga: Chapter 149, Page 8 Erik has also shown to be able, with his Dragon Slayer Magic, to completely crush the Rock Dragon's scales with a mere punch.Fairy Tail Manga: Chapter 330, Page 10
Expert Hand-to-Hand Combatant: Erik has been shown to be proficient in unarmed combat, employing fluent motions to rapidly strike his opponents. His hand-to-hand skills are complemented by a high degree of agility, with Erik being capable of perfectly maneuvering and dodging attacks while remaining on Cubellios' back.Fairy Tail Manga: Chapter 149, Page 19 The power of his strikes is greatly increased when he makes use of his Dragon Slayer Magic, which allows him to also poison his opponents on contact.
