"I want to see and understand the world outside. I don't want to die inside these Walls without knowing what's out there!"

The main protagonist of the series. An aggressive young man with two defining passions: his desire to explore the world beyond the Walls, and his hatred towards the Titans. His grudge against the Titans is catalyzed further into a murderous rage when they invade his home town and he is helpless to save his mother from being devoured. When he graduates the 104th Training Corps, he is ranked 5th overall and he intends to join the Survey Corps.

During his military training he is judged to be of average skill and talent for Titan killing and 3DM maneuvering, but through sheer hard work he is able to graduate 5th out of his class with notable checkmarks on hand-to-hand combat. After a near-death experience during the Battle of Trost, he discovers that he possesses the ability to create and control a Titan body, transforming himself into a Titan. This revelation makes him a target for several opposing factions, who either view him as a threat or the key to humanity's survival.

Eren is forcefully enlisted into the Survey Corps to be kept in check by Captain Levi Ackerman, to be used for explorations outside the Walls by Commander Erwin, and to collaborate in Titan-related experiments performed by Hange Zoe. Most of his fellow 104th top-10 teammates follow suit and join him in the Corps. However, his inexperience with the power means that he struggles to transform into anything that is not a berserker fueled by blind hatred at first. Even after he learns to gain some measure of control, the experience gap places him at a distinct disadvantage against his main adversaries.

After Eren is captured by enemy forces, he awakens his most powerful ability and the main reason the Titan Shifters were after him: the power to control other Titans. In the next arc, he becomes a target for kidnapping again, this time alongside Historia and by a dangerous enemy faction hiding within the Walls.

Four years after reclaiming Wall Maria, Eren has used the war between Marley and the Mid-East Alliance to infiltrate the mainland. Disguising himself as a wounded soldier, he travels to Liberio and befriends the Warrior cadet Falco Grice.

    open/close all folders 

    A – B 
  • Above Good and Evil: After suffering from Black and White Insanity, Eren starts believing that freedom is the most important objective and justifies his ruthless methods.
  • Action Hero: His modus operandi. At the end of the day, fighting is how Eren usually chooses to solve his problems.
  • Adaptational Attractiveness: A mild case. He's rather handsome in both mediums, but his face is rounder and his cheeks are noticeably fuller in the anime, making him more conventionally "cute" (especially as a child) than his manga counterpart.
  • Adaptational Badass:
    • The anime throws him a bone and let's him fare a bit better in his rematch against the Female Titan. In the manga, she all but defeats him and cripples him beyond movement by kicking off his leg and then bashing his head in (although his Healing Factor kicks in quickly). In the anime, he actually manages to get up from this and tackles her while hopping on one leg, eventually managing to decapitate her with a punch.
    • In the manga, Eren's skill with the 3DM gear is largely considered middling at best and it takes him a while to develop a decent capability with it. In the anime, Eren is already capable of doing fancy, acrobatic spins in the air using the gear by the Battle of Trost and generally maneuvers around with dexterity and grace as if he were Mikasa. Somewhat rectified during one scene in Season 2 though, where he gets his 3DM wires tangled up killing a Titan and clumsily flops to the ground - though considering he's spent more time fighting as a titan rather than a human, his getting rusty would be justifiable.
  • Adaptation Distillation: His relationship with Annie is downplayed in the anime, as it skips some scenes from the manga showing her mentoring him in combat. Consequently, his adamant denial of her identity as the Female Titan and hesitancy to fight her (which Mikasa unhappily speculates is due to "special feelings") has a slightly weaker justification.
  • Adaptation Dye-Job: Both the windows and curtains. Eren has dark brown hair and vibrant green eyes in the anime which is a clue to him being the Rogue Titan, but jet-black hair and steely grey eyes in the manga.
  • Adaptation Expansion: During his second fight with the Female Titan, his calm teamwork with Armin and Mikasa to capture her is replaced in the anime with Eren losing control of his Titan form and going berserk, chasing down the Female Titan and brutally beating her down. However, despite going berserk, Eren still hesitates upon seeing a crying Annie, which allows her to crystalize herself.
  • All for Nothing: Invoked. All his efforts to protect Historia from harm are amounting to nothing when the military junta allows time to pass, closing dangerously into Zeke's time limit for his plans regarding the Paradian Eldians and their allies, as the Curse of Ymir will kill him in mere months' time. As such, Historia is forced into pregnancy to produce heirs and is prospected to inherit the Beast Titan from Zeke (following the plan), basically conceding everything while achieving nothing for themselves. As such, and due to their inaction, Eren is forced to attack Liberio. As of Chapter 107, all is going according to Zeke's plans, while the military junta and Hange have been basically sitting on their hands and allowing every advantage they have to be taken away from them.
  • Always Save the Girl: As a part of Characterization Marches On, Eren correctly deduces that Falco is hoping to save a girl (Gabi) from the horrible fate of inheriting a Titan power and having a shortened life span. Eren was shown to be rather thick-brained regarding the concept of romance during his youth, so it's rather telling that he is at least able to pick up the clues to make the deduction. He wasn't going to stay a boy all his life!
  • Ambiguous Disorder: Even before his life was ruined by Titans and he became justifiably bitter, Eren was always unusually antisocial, cold, and prone to bursts of anger as a child, which his father candidly pointed out at the time. His brutal, fearless, and completely unfazed butchering of two grown child slavers at the age of nine (having never committed a major act of violence like that beforehand, either) was probably the point where it became clear he's never been quite fully right in the head. The various traumatic and violent events in his life that followed have not helped him, as you can imagine.
  • And Then John Was a Zombie: Not that he minds being a Titan.
  • Anti-Hero: He's an idealist in a cynical world, he wants the best for humanity, and his gift is stated to be his Heroic Resolve. What muddies up his status as a straight-up hero is that he's fueled by his hatred for all Titans and his Unstoppable Rage can be absolutely terrifying to behold.
    • After the Time Skip he is of a different variety than what he was at the start of the series. He is no longer a revenge-fueled berserker, but his actions have become more morally questionable. He manipulates a kid who into helping him in his conquest against the kid's country, threatens to kill a bunch of civilians to Reiner, and then proceeds to carry out that threat by transforming, killing many men, women, and children in the process to assassinate Willy Tybur.
  • Ape Shall Never Kill Ape: He gains the specific ability to defy this trope thanks to his power to command Titans, as well as being able to do it himself as a Titan Shifter. Following Hannes' death, Eren unconsciously directs mindless Titans to rip the Smiling Titan into pieces, and later hinders Reiner and Bertholt by turning the horde against them.
  • An Arm and a Leg: His arms and legs are repeatedly severed over the course of the series, but, thanks to his Healing Factor, he always recovers them.
    • As part of his disguise, he's missing his left leg below the knee. It appears that he has gained control over the regrowth of his limbs in the time skip. He may have also lost an eye as well, though whether he has or not is hard to tell with the bandage over it. Either way though, he's shown to have both eyes by the time he removes the bandage.
    • His healing factor has improved dramatically the past 4 years, as he can now regenerate an entire leg in seconds. For reference, it used to take him hours to heal that much.
  • Attack! Attack! Attack!: His default strategy against Titans is "attack relentlessly until it's dead" with varying results, in Titan form this works okay in human form not so much. He later manages to avert it during his battle against the Armored Titan, once he manages to calm down enough to start using tactics.
  • Awesomeness by Analysis: He learned one of Annie's fighting techniques after seeing it only twice.
  • Ax-Crazy: Subverted. Eren is normally too rational despite his obsession with revenge, and his berserker moment occurred when Eren had no conscious control over himself. One of the main aspects of his arc is to show how he gradually gains control of his Titan form from the Lotus-Eater Machine stupor experienced by mindless Titans to a more manageable functional state under his full command.
  • Badass Boast: He has had several.
    • From the manga:
      Eren: Humanity will feast on the Titans.
    • From the anime:
      Keith: ... or will you become a glorious soldier who exterminates the Titans? The choice is yours.
      Eren: Yeah, I will. I'll exterminate every last one of them.
    • After he finds out that Reiner and Bertolt were the Armored and Colossal Titans:
      Eren: I will do everything in my power... To make your deaths as excruciating as possible.
    • While inside a Titan's stomach.
      Eren: As if I'll give up! I'll exterminate you, every single one of you! Me! With these very hands!note 
    • As a child:
      Eren: I put down some dangerous animals. Animals that just happened to look like people.
  • Badass Family: After being put through hell after the death of their mother, Eren and Mikasa have become quite skilled at slaughtering Titans. And this applies doubly once Eren begins harnessing his powers as the Rogue Titan.
  • Badass in Distress: After a close fight with Annie in her Titan form, Annie is able to defeat him when he is distracted and he is swallowed, forcing Levi and Mikasa to rescue him. Happens again in Chapter 45 after a close fight with Reiner, Bertolt bodypresses him (in Colossal Titan form, from the top of the wall) , giving Reiner the opportunity to swallow and abduct him. And even when he awakens to discover both his arms missing, he continues to resist his captors, including PUNCHING Reiner in the face with his stumps repeatedly. It doesn't work out, but points for trying.
  • Bad Liar: According to his mother, Eren's ears turn red when he lies. However, this is otherwise subverted because Eren has been shown to be an excellent Consummate Liar and actor when dealing with other people. Perhaps he simply couldn't fool his mother's maternal intuition though.
  • Barbarian Long Hair: He's wearing his hair long and unkempt, as part of his cover as a traumatized soldier. It also helps obscure his face.
    • When he returns home, he cleans himself up and throws half of his hair into a bun, presumably how he actually wears his hair now.
  • Beard of Sorrow: Initially leaves himself unshaven, since he's posing as a traumatized soldier. Upon returning home, he shaves it off with hardened resolve to fight Marley.
  • The Beastmaster: In Chapter 50, he develops the ability to direct Titans. So far, he has not used this ability since and seems to have no conscious control over it.
  • Be Careful What You Wish For: The military at Paradis basically toted Eren as humanity's greatest weapon, which in turn made him into a "savior", or a "messiah" of sorts. What's the problem with that? Well, a messiah doesn't have to answer to any authority, does he?
  • Because You Were Nice to Me:
    • The main reason Historia outright refuses to devour him to gain the Coordinate. Eren is the first person that recognizes Historia as an individual (even praising her for dropping her facade and voicing her opinion) and not just as a placeholder for other people's agendas. She also recognizes that Eren is her friend, and she doesn't want him to get hurt.
    • He befriended Falco because he remembers him being the only one to stop and help him when he pretended collapsing due to injury and PTSD. It isn't a pure friendship on Eren's part as he uses Falco to lure Reiner into a trap of sorts with Falco being completely unaware he's being used.
  • Berserk Button: The Titans in general and human existence under them are one giant Berserk Button for Eren.
  • The Berserker: He has pretty serious rage issues. Especially in his Titan form.
    • His entire fighting style as a Titan consists of roaring, smashing to a bloody pulp, rinse and repeat.
  • Berserker Tears: Against the Female Titan and basically every time he is crying.
  • Betty and Veronica: The official parodies portray Mikasa and Annie as these, respectively, with him oblivious to their affections.
  • Big Bad: Invoked and played with.
    • He was declared as such by Willy Tybur, labeling him the "enemy of humanity"; thing is, Tybur and the Kingdom of Marley provoked him. And from the perspective of the Marleyans we have spent the past chapters following, he certainly seems like one after Titan-shifting in the middle of a crowded square, killing a bunch of random civilians in the process of killing Willy Tybur and the Marleyan command.
    • After the attack on Liberio is carried out, and having witnessed his callous reaction to Sasha's assassination, his fellow Survey Corps partners of the 104th speculate that Eren might not be vying for their well-being anymore. He later leads an uprising against the Military Junta and puts his friends in custody.
  • Big Brother Instinct: Inverted, Mikasa acts this way towards him. He hates it though.
    • Played straight with Armin, though they're about the same age.
    • Later he even shows traces of this towards Krista, telling her he likes her better when she's not constantly faking a cheery attitude, and is also the one who calms her down when she's in tears after Ymir left with Reiner and Bertolt.
  • Big Damn Heroes: As the main character, he's bound to have some of these.
    • His first meeting with Mikasa. He tracked down the human traffickers who'd kidnapped her and made a beeline for their hideout, knife at the ready.
    • His first appearance as the Rogue Titan, saving Mikasa after she ran out of gas.
    • After he has his powers under control, he carries the large rock and seals the hole, giving humanity their first victory against the Titans.
    • His biggest one yet is in Chapter 50, everything is going from bad to worse. The soldiers are being slaughtered left and right by Titans, Erwin lost an arm, Mikasa is hurt, Hannes was just eaten, Reiner is coming for Eren, Jean was knocked out by Reiner throwing Titans everywhere, Armin being forced to protect him, and Eren is having a Heroic BSOD over Hannes' death. After Mikasa breaks him out of it, Eren awakens his new power to control Titans, he swarms the normal Titans to brutally murder the Smiling Titan, then turns his attention on to Reiner, giving the humans the time to escape.
  • Big "NO!": Eren screams out one of these as his mother is about to get eaten. In the anime, his scream of "YAMEROOOOOOOOOOOOO!" note  has all the intensity of one of these.
  • Bishōnen: In the manga, he seems to have a Long-Haired Pretty Boy look going on by the time he's 16.
  • Black and White Morality: His view of the world is very much this, so much so that he feels absolutely no remorse for brutally murdering criminals and even becomes angry at Reiner for having guilt over his crimes. It borders on Black and White Insanity in some cases.
  • Blatant Lies:
    • Played with. He callously tells Mikasa that her attachment to him is artificial due to her Ackerman conditioning, and that as such, she has no free will and no control over her actions; however, another Ackerman in the form of Levi, is not attached or bound to anyone like Mikasa is, and his attachments like Erwin and Hange are nowhere as profound as Mikasa's with Eren. As such, it's implied that at least partly, Eren is undermining Mikasa's sincere love for him. Another overlooked aspect of this is that Mikasa is just as defensive of Armin as she is of Eren, further undermining her conscious choices to take care of her dearest friends.
    • To further elaborate on the previous point, Eren makes a point of capturing the Survey Corps and directly telling the previous to Armin and Mikasa, instead of being done with them and just executing them altogether. As such, it's implied that Eren is acting like a Hidden Agenda Villain, and severing his attachments to his friends has a point and a purpose.
  • Blue and Orange Morality: Eren operates on Freedom vs Ignorance morality. He deems those who are ignorant as despicable which sadly includes Mikasa and Armin.
  • Bound and Gagged: He's been tied up more than anyone else. This is due to the fact that Self-Harm is a trigger for his transformation so keeping him from biting his hand is everyone's main priority.
  • Boxed Crook: He becomes one, after his powers are discovered. Levi and his hand-picked Special Operations Squad are given orders to keep him under control, and kill him if necessary. When the 57th expedition fails, he's almost taken back into custody and the threat of execution is never far off should the government decide he's too dangerous or not useful enough.
  • Brainwashed and Crazy: Zeke refers to Eren as being a victim of this by his father, and given Eren's memory problems and what was learned about Grisha through Frieda Reiss's memories, there's a very strong chance he's not lying.
  • Break the Haughty:
    • Has a brief bout of this during training. After talking big and saying weaklings should just drop out of boot camp (although it was an anime-only scene), he earns little pity upon discovering that he seems to have zero natural talent when it comes to the 3D maneuvering system. His Determinator spirit returns when it's realized that his lack of progress was due to faulty equipment.
    • After learning that he was The Unchosen One, Eren beats himself up (figuratively and literally) for ever thinking he was "special."
  • Break Them by Talking: After the Time Skip, he's become incredibly skilled at breaking people down psychologically. At Liberio, he forces Reiner into discussing the Paradis Operation and nearly breaks his will in the process. In Chapter 112, he uses the same tactics to take Mikasa and Armin prisoner, threatening to transform to keep them restrained while breaking them down through precise insults and accusations. He claims that Armin has been compromised by the influence of his predecessor, Bertolt. And he claims that Mikasa's affection for him is because her heritage as an Ackerman makes her a slave.
  • Broken Pedestal:
    • Deeply admired and looked up to Reiner, leading to a complete destruction of the pedestal when he learns that Reiner is the Armored Titan. He expresses disgust over his former hero's deception and hypocrisy.
    • Falco comes to greatly admire "Mr. Kruger" for his support and good advice, even going so far as to sneak letters out of the ghetto for him. Then he learns the truth about Eren, and realizes he's been helping the enemy infiltrate Liberio. To say Falco is devastated is putting it lightly.
    • His fellow 104th partners start thinking that the Eren that declared his affection towards them is long gone.
    • "And the only way to win is to fight. So fight and fight."
  • Broken Smile: Sported a brief one upon learning that Marco was dead.
  • Broke Your Arm Punching Out Cthulhu: Eren does this quite literally every single time he fights other Titans. He once lost both his arms doing it, and most of his ribs.
  • Brutal Honesty: Interestingly, he's actually a very good liar when he needs to be, but he seems to prefer not to; instead, expect Eren to always share his opinions as bluntly as possible. After Historia shared her concerns with him, he bluntly told her that he found her creepy when she was trying to act as a Nice Girl, although he adds that he actually likes her true self as Historia, considering her an honest and normal person.
  • Bully Hunter: The story was inspired by Hajime Isayama's memories of bullying in school, and thematically, Eren's that small, scrawny kid who refuses to be let people push him around no matter how many times he gets knocked down.

    C – E 
  • Call-Back: The ending of Chapter 106 has him and Mikasa recite their survival mantra, however, hardened by the loss of Sasha and distrust of his comrades, Eren spins a new take on the end.
  • Came Back Strong: His near-death experience triggers his Titan Powers.
  • Cannibalism Superpower: His Titan Shifter power comes from having eaten his own father after being turned into a Titan. He also inherited the Coordinate ability, which his father had gotten by eating Frieda Reiss.
  • Can't Kill You, Still Need You: Invoked by Eren. He tells Hange that as the holder of the Coordinate, he's too valuable to be harmed, and that as the holder of the War-Hammer Titan, it's basically pointless to contain him. As such, the Eldians of Paradis are effectively dancing to his song, no matter what pretensions they think they have.
  • Character Development: He's grown more introspective and thoughtful from his many experiences. Since he has a lot of mistakes to make up for, he has developed some crippling self-doubt. However, because he can reflect on his experiences and what went wrong before, it all culminates in a moment where, despite everything he's been through, he chooses to bet on himself once more.
    • Chapter 70 shows you how much Eren has changed as a character. His rant from "I want to kill Reiner and Bertolt and give them the most excruciating death ever" changes to "I must kill them regardless of whether I want to or not." When prompted by Historia about whether he wants to or not, he seems to hesitate and only replies that he must.
    • In Chapter 72, Eren admits to both Armin and Mikasa that he used to resent Mikasa's strength and wished that he could be as strong as her or Levi. But, after everything he has experienced, he now knows that everybody has a role to play.
    • Eren has become considerably more mature, stoic, and worldly during the Time Skip, likely due to maturing, his experiences, and receiving the memories of his father and his namesake. This comes full circle in the 100th chapter, when confronting Reiner after years apart. As opposed to the angry young man that saw his enemies as "not human", Eren is able to recognize the humanity of his enemies and the tragedy of their situation. This extends to him offering sympathy to Reiner, and shrugging off the idea of carrying out his past threats of revenge. On the flipside, he has also become capable of rather cold acts of cruelty, such as Titan shifting in the middle of a crowded square full of Marleyian civilians who are completely innocent of Marley's war on Paradis and even victim's of Marley's oppression. Mikasa notes with horror that in the process of killing Willy Tybur, Eren caused the deaths of many innocent men, women, and children.
  • Character Name Alias: In-Universe. He's borrowing his namesake's surname as an alias, going by "Mr. Kruger".
  • Chaste Hero: He seems to be utterly uninterested in anything romantic, to the extent he states that he found Krista to be somewhat "creepy". This trait is played up in official parodies, with Eren viewing Mikasa and Annie as One of the Boys.
  • Chekhov's Skill: During training, Eren's only remarkable skill was his proficiency in hand-to-hand combat, which he admits is pointless when facing Titans. At least, it would be if not for the fact Eren can turn into one.
  • Chick Magnet: Official parodies potray him as such and he is a muted example in canon with him being the center of Mikasa's world and Annie's hinted fondness as well as becoming close to Historia.
  • The Chosen One:
    • Considering his prophetic dream at the beginning of the anime, and its puzzling counterpart in the manga with the Mysterious Girl, and also adding to the memories of Grisha Yeager and Eren Kruger that he later inherited (keep in mind, this all happened before Eren gained the Attack Titan), it's heavily implied that Eren was always meant to inherit the Attack Titan.
    • As the military junta poises him as the flag-carrier for their cause, his followers and the public in general at Paradis see Eren as a messiah of sorts, who will lead them in glorious victory against their enemies. Of course, the junta loses control of Eren completely, as it's implied that Eren both drank the Kool-Aid and is being led by the nose by his brother Zeke's agenda.
  • Chuunibyou: The primary explanation Levi makes for Eren's sudden outbursts and tendency to talk to himself in Chapters 88 and 89. The truth is far more horrifying.
  • Clark Kent Outfit: Though he looks to be somewhat on the scrawny side with his shirt on, Eren's military training has actually left him pretty shredded.
  • Combat Pragmatist: During his fight with the Warhammer Titan, she crystalizes her actual body so he cannot eat her, his jaw breaks upon trying. A bit later, while defending himself from an attack from Porco's Titan form, he notices that Porco scratched Lady Tybur's cocoon. So he uses Porco's Titan form's jaws to manually crush Lady Tybur's cocoon, and lets the blood pour into his mouth, seemingly giving him her Titan form.
  • Compelling Voice: Erwin theorizes that his voice can be used to influence not only Titans, but humans as well. Turns out it can, but only in the hands of the Reiss family.
  • Consummate Liar: He doesn't bother with lying most of the time, but as seen in Mikasa's backstory, he can act very convincingly, enough to make hardened criminals temporarily lower their guard.
    • He's gotten quite good at deception, no doubt another skill he picked up from Reiner. Not only was he able to convince the doctors he had PTSD-induced amnesia, he also manages to convince Falco to deliver a letter to ensure its contents wouldn't be checked by the authorities by having Falco think that it was merely to let his family know he was safe. The rub of it is they're not outright lies either. He is a War Vet, and he does show many signs of shell-shock (distant stare, lack of expression, difficulty in making conversation...); he just let them assume that he was on their side, as Reiner did years ago.
  • Conveniently Unverifiable Cover Story: Something he learned from Reiner. He claims to be a man named "Kruger", so traumatized by his experiences during the war that he can't even remember where he lives. As all the patients are suffering from PTSD and have no family to claim them, his story is accepted by the hospital staff.
  • Cover-Blowing Superpower: Averted. He's now able to suppress his regenerative powers to keep his leg from growing back, making his disguise even more elaborate. He's also able to suppress his Titan form should his hands be injured, as evidenced with the nasty gash he has in Chapter 99.
  • Crazy Sane: Seriously, if his Unstoppable Rage and Titan Shifter powers weren't extremely useful against the Titans, he'd probably get locked up in a mental hospital.
  • Creepy Child: He violently murdered two men at the age of seven, and Hannes admits he always found Eren a little scary because he was so intense.
  • Cry Cute: In the anime, he begins an angry tirade against the military after they callously give him and his friends food and shelter. Mikasa knocks him down from his high horse, arguing that his attitude won't keep him alive and that she won't allow him to endanger himself or die on her watch by not abiding to their rules, shutting him up by shoving a loaf of bread on his mouth. Defeated, Eren breaks down and cries at the helplessness of their situation.
  • Cursed with Awesome: Being a Titan Shifter. Humans regard him as a liability (at best) or an abomination (at worst) but it's extremely useful for Titan-slaying, grants him a useful Healing Factor in both Titan and human forms, gives him an outlet where Unstoppable Rage is actually a good thing, and may very well be legitimate hope for the survival of humanity. He later gains a power that is undeniably useful: Controlling Titans. However, this is the reason that he is being targeted by the enemies of mankind and may be part of the reason they attacked the city and ruined his life to begin with.
  • Cute and Psycho: How he's looked at by people outside of his closest friends and family as a 9 year old. The military bring up his actions during his trial to question his humanity.
  • Dare to Be Badass:
    • You can bet money that this is his response to anything resembling apathy, doubt, or cowardice in others. A good example is when he rallies the panicking and doubtful Trainees right before the battle for Trost, exhorting them to be strong as they've already shown through 3 years of hellish training that they are strong. Most notably he's had a profound effect on Mikasa (see her entry below).
    • Does this to himself in Chapter 50 after Mikasa thanks him for all he's done for her declaring he'd do it a thousand times over if he had to and tries to take on a Titan with his bare hands
  • Dead Guy Junior: Eren was probably named after Eren Kruger, a man who had a big role in Grisha's backstory and was also the host of the Attack Titan before Grisha; the same power that this Eren now possesses.
  • Deadpan Snarker: Eren can be pretty sarcastic at times, but he tends to be at his snarkiest when he's not saying anything at all.
  • Death Seeker: Averted, despite what the majority of his allies think of him. See Not Afraid to Die.
  • Declaration of Protection:
    • He gives one to Mikasa, declaring that everything he has done for her, he'd do all over again.
    • After Eren and Historia reaffirm their friendship, Eren makes a vow to not let her be a pawn for political purposes, like the way her father tried to manipulate her. His failure to do so after the timeskip greatly angers him.
  • Deconstructed Character Archetype: Many of Eren's tropes are not unusual for shonen protagonists, but what is unusual is that they are treated more realistically by have as many negative consequences as positive ones for him. Determination is essential for a soldier and especially for one fighting The Dreaded, but rushing blindly on determination alone will get you or someone else killed. If he wasn't a Titan Shifter he'd be have fairly little to show for his determination, and be dead. He is called on his stupidity, suffers defeats aplenty, and practically all Eren's victories come with active support from friends and allies.
  • Decoy Protagonist:
    • Subverted. He's maimed and eaten in the first major battle, which seems like the perfect start to a Stuffed into the Fridge scenario to motivate the more skilled Mikasa or stir then cowardly Armin to heroism, until it's revealed that Eren is a Titan Shifter and escapes.
    • In a way, he is this to Historia. Not only is she the true heir to the monarchy of the walls; but the very powers Eren possess rightfully belongs to the Reiss bloodline to begin with, meaning, his powers were meant for her. This leads to his Heroic BSoD as he starts to think himself as worthless and in the way of what should have been Historia's quest of slaughtering Titans and not his, until she snaps him out of it.
    • In an overall sense, even after coming back as a Titan, Eren has been mostly out of focus and he mostly seems to serve as The Big Guy. The cast seems to function more in an ensemble with plenty of different view points just as important (if not more) as Eren's.
  • Designated Victim: He is either severely injured or kidnapped in every major arc so far. He Lampshades this in Chapter 62.
  • Despair Event Horizon: He finally breaks after learning he is the only reason the Reiss family is unable to save humanity from the Titans, which would make every sacrifice for his sake meaningless.
  • Determinator:
  • Deus ex Machina: The ending of Chapter 66 has everyone trapped in a collapsing cave, when Eren suddenly notices Rod's bag that just happened to lie right next to them and contain a serum for an "armored" Titan, the type of Titan ability Eren had tried hard at mastering beforehand and is exactly what they needed to escape the situation.
  • Devoured by the Horde: It turns out he has the power to invoke this when he used this odd scream to get a bunch of Titans to gang up and tear apart the Titan that killed his mother years ago.
  • Did You Just Punch Out Cthulhu?: In Chapter 50, after recovering from his Heroic BSoD, he blocks the Smiling Titan's hand, and then punches it, before using his Coordinate powers to sic a horde of Titans on it.
  • Die or Fly: His Titan-shifting powers awoke when he was in the belly of the Titan who ate him, and his ability as the Coordinate manifested when his group was surrounded by Titans outside the Wall with little hope of anyone getting out alive.
  • Dissonant Laughter: Invoked and played with. In Chapter 105, he laughs when he first hears Sasha's dying words ("meat"), as they brought up one of his fondest memories of her, when she stole a ham from the Officer's kitchen right before the Colossal Titan attacked the district of Trost. Later, in Chapter 108, Connie, who witnessed his laughter and smile, took great offense at this, as he's under the impression that Eren was laughing at the fact that Sasha died. Regardless of Eren's actions, it was hardly the time for him to laugh.
  • Dissonant Serenity: At the end of Chapter 98 when he confronts Reiner. He's surprisingly cordial, even saying he that he's glad that Reiner got to go home. But he's also staring him down with his one viable eye, in the same vein as a hunter eyeing his quarry. It's a bit unsettling actually.
  • Distressed Dude: He's frequently the victim of kidnappings or kidnapping attempts. First by the Female Titan, then by Reiner and Bertolt, and now by the 1st Brigade.
  • Do Not Go Gentle: When he faces what seems like certain death, instead of sitting down and accepting it, Eren gets up and tries to punch a Titan.
  • Doom Magnet: Since the Titan Shifters want to capture him, a lot of Titans inevitably end up appearing and many soldiers wind up dying as a result.
  • Don't Celebrate Just Yet: A year after Bertoldt attacked Trost, the Titans have finally been (mostly) cleared from Paradis Island and Eren and Armin finally get to see the ocean with their own two eyes. But while Armin and the Survey Corps celebrate, Eren just gazes ominously into the distance instead, reminding everybody that they can't truly be free until they've dealt with their enemies.
  • The Dreaded: Willy Tybur officially designates Eren as such during his announcement, saying that Eren wishes to completely undo the peace Karl Fritz worked so hard to achieve after taking the power of the Founding Titan, and is currently the single greatest threat to the entire world. Shortly afterwards, Eren shifts into the Attack Titan and assassinates Willy in full view of the entire international community.
  • Early-Bird Cameo: He made his first post-Time Skip appearance tailing Reiner in Chapter 93 (p.36) with just his back facing the readers, and then as the Shell-Shocked Veteran Falco stops to help in Chapter 94, his true identity not being revealed until Chapter 97.
  • Empowered Badass Normal: Pretty badass by himself — he's ranked fifth in his class — but discovers his Titan-shifting powers after he gets eaten by a Titan.
  • Enfante Terrible: Even as a child, there's always been something a bit off about Eren. His father implied he was very cold and anti-social, noting that Armin was his Only Friend. At the age of nine, he planned and carried out the brutal killing of two grown men to rescue Mikasa. While it was ruled justified, the soldiers sent to the scene were shaken by what two children managed to do to three adults. Even before his mother's death, Little Eren was a little unstable.
  • Equivalent Exchange: This is the ugly truth behind Titan-shifting; any Titan who consumes a Titan Shifter will gain their normal body back as well as the power to transform into one of the nine Titans themselves... but, their human body will progressively weaken from there on out and they will die in 13 years. In Eren's case, this means he'll live to be no older than 23.
  • Et Tu, Brute?: For all his pathological hatred of Titans and criminals in general, he's very distressed to learn that his own mentor and comrade Annie was the Female Titan responsible for the slaughter of the 57th expedition, and (in the manga) can't bring himself to express hatred towards her (while hesitating to harm her personally in the anime as well). By the time he learns about Reiner and Bertolt however, his Black and White Morality returns in full effect and he wants nothing more but to kill them "as excruciatingly as possible".
    • The reason he didn't freeze up was because had some warning The Survey Corps knew that there was more than one shifter in their ranks and Reiner and Bertolt were the most suspect. Eren had been in the know about this since he and a few other members of the crew had been ordered to keep a close eye on them. He still took it pretty hard, hence his outburst.
    • Another example is also in Chapter 83, when Levi promised to give Armin the Titan serum but changed his mind upon seeing Erwin still alive/in critical condition. Eren's face when he confronted Levi was one full of fury and nothing less than intimidating.
      • Not that had any effect on Captain Levi.
  • Eureka Moment: After successfully reclaiming Wall Maria, Hange and Zackly later discuss how Eren was able to use the "Coordinate" ability unimpeded by the First King's Will despite not having Royal Blood. As they're talking, Eren thinks back to what happened, and comes to the shocking revelation that because the Smiling Titan was originally Dina Fritz, his father's first wife and a member of the Royal Family, making physical contact with her Titan form when he punched her hand allowed him to use the "Coordinate" ability for a short time. However, Eren decides to keep this information to himself out of fear for what might happen to Historia.
  • Evil Overlord: Eren masterminded the assault on Liberio and killed many innocent civilians as collateral damage. He stole Marley's War Hammer Titan and Eren continued to spread his influence. In the blink of an eye, many partisans and a large chunk of the Survey Corps formed the Yeagerist group and Eren became its undisputed leader. For his exploits, he won the support of the Paradis public who were disgruntled by their government's policies. Just one day after escaping from prison, Eren assumed absolute control over all of Paradis and his followers held the top brass of the government and military hostage. Eren has no qualms taking Armin and Mikasa as hostages.
  • Extreme Mêlée Revenge: Killed a grown man as a child, by stabbing him over and over (and over) again while screaming in a murderous rage. He also has a tendency towards this when fighting in his Titan form, especially during his first transformation.
  • Eyepatch of Power: He wears bandages over one side of his face, helping obscure his true identity from the few that could recognize him. Given the Manga's heavy use of Norse Mythology, this also makes him resemble Odin, the One-eyed King of the Gods.

    F – I 
  • Face of a Thug: Armin even says he and Jean have the look of a criminal in their eyes. This comes up later when Jean pretends to be Eren so he can escape from the capital and probable execution. Interestingly, he doesn't object to looking like a thug, just that he doesn't have Jean's horseface.
  • Facial Horror: When his Titan-shifting ability is pushed to its limits, Eren can barely eject from his Titan body, and his face ends up partially melted off. He recovers. He also happens to be shirtless in this scene.
  • Failed a Spot Check: How Eren managed to overlook something as crucial as putting his armband on the correct arm despite having Grisha's memories and diaries from his life in Marley is anyone's guess. If it weren't for Falco's intervention, his cover may have been blown.
  • Failure Hero: The foundation of Eren's struggle; he is a weakling in a cruel world. Throughout the story, Eren fails repeatedly and suffers for his mistakes, but he comes back a little stronger and a little wiser every time.
  • Fanservice Pack: Not that there's much fanservice in the series, but the end of chapter 106 shows that Eren has definitely gotten bigger in the previous four years.
  • Fatal Flaw: His hotheadedness and inability to control his rage would have gotten him killed at Trost if he hadn't lucked out with his then-unknown Shifter powers. Later, he's in the company of two people who know a great deal about Titans and the other mysteries of the plot while in a situation where there's nothing they can do but talk. Eren knows that his best course of action is to grill them for information and specifically acknowledges that he needs to keep his temper. Even so, one off-color remark sets him off threatening to brutally murder them, and he (and the audience) learns nothing.
  • Fearless Fool: Jean in particular considers him one, and many consider his over-confident attitude concerning the Titans a death wish. He's beginning to learn to pick his fights, but only after several very harsh lessons.
  • Fighting Fingerprint: After Annie kicks his ass and teaches him her technique, he adopts it as his main fighting style. One of the strongest hints that the Rogue Titan is him is that it puts up the same boxing stance and uses the exact same techniques shown earlier.
  • Fighting Your Friend: During his training session with Reiner, he was against practicing with his teammates but accepted it after his discussion with him. This is played straight when he has to fight Annie and subverted after he discovers Reiner and Bertolt's true identities.
  • Fight Magnet: He tends to draw in battles with Titans and pick fights with people that he disagrees with.
  • Friendly Enemy: While accepting their positions make them foes, Eren is perhaps the only person to really understand Reiner's suffering and offers him sympathy. It speaks volumes for their situation, that Eren is the first person Reiner is able to open up to after a lifetime of lying.
  • From Bad to Worse:
    • The Warriors try to sway him to their side under the impression that he only has the Attack Titan power; it turns ballistic when they realize that he has the Founding Titan too.
    • His friends speculate that Eren is not on their side anymore due to his liberal careless attitude towards the attack on Liberio and Sasha's death. He later leads a revolt against the Military Junta and personally puts them in custody.
  • Glad He's on Our Side: Even as he slowly gains the trust of the soldiers in his squad, most of humanity remains fearful of him. And for good reason.
  • Glass Cannon: As a Titan (his human form is automatically a Fragile Speedster like everybody else, of course). He's strong even by Titan standards and his punches are devastating, but his body is still surprisingly frail like a typical Titan and Gorn typically ensues as he breaks and sometimes completely severs his limbs from the force of his own attacks.
  • Good Thing You Can Heal: The Healing Factor that comes with being a Titan Shifter has saved him more than once, and it means that he can shrug off dismemberment and at one point having his face melted completely off.
  • Green Eyes: In the anime, his eyes are a vibrant green. It's one of the few features he has in common with his Titan form.
  • Guilt-Free Extermination War: The overall goal of the humans but Eren is hateful enough to declare he'll kill every Titan by himself.
  • Hair-Trigger Temper: Before the fall of Shiganshina he gets extremely angry easily by people not taking the military seriously (either civilians or slackers like Hannes) and frequently picks fights with delinquents over trivial things. After watching his mother get eaten just about everything pisses him off (but nothing more than the Titans).
  • Hate at First Sight: According to him, towards Mikasa.
  • Hate Sink: Could very well be becoming one as his means to accomplishing his ultimate mission become increasingly extreme and amoral, and is no longer worried about the consequences of civilian casualties in achieving his ends. His vicious actions towards both Mikasa and Armin while in the midst of taking the majority of the Survey Corps hostage in Chapter 112 certainly also cement him as this, even as his true intentions remain as of yet unclear.
  • Head Butting Heroes: He frequently butts heads with Jean, Mikasa, and to lesser extent Armin.
  • Healing Factor: As a Titan Shifter, he passively heals at a rapid pace, even regrowing whole limbs in a matter of hours.
  • Heroes Fight Barehanded: He's the best hand-to-hand combatant in the 104th, having trained extensively in it during his boot-camp days. At first it doesn't seem like a useful skill given the size difference between humans and Titans, but when his nature as a Titan Shifter is revealed it becomes a very good thing because it gives him a massive edge when fighting other Titans.
  • Heroic BSoD: Once he knows that Annie is the Female Titan, he can't bring himself to transform and fight her, not even to save himself when he's getting crushed. It takes several of his friends yelling at him, including Mikasa, Armin, and Jean, then the memories of his mother getting eaten and the Special Operation Squad getting killed before he finally snaps out of it. It is a sight to behold. This happens only in the anime version, in the manga he snaps out of it much faster, just as Armin and Mikasa go off to distract the Female Titan.
    • When he finds out that some of his friends are Titan Shifters instigating mankind's destruction, he does not take the news well.
    • He has a nasty one when Hannes is eaten in front of him, making him feel completely useless. It takes Mikasa reassuring him of everything that he has done for her to break him out of it, and when he does...
    • When he sees the Titan who ate his mother approaching him and Mikasa, he completely shuts down. It takes her confessing how much he means to her to snap him out of it.
    • Suffers another one when he discovers that he is pretty much, in his own words, "unnecessary" due to the Reiss family being able to eat Titans and therefore absorb the memories that he received from Frieda. He even refuses to turn when Kenny wounds him, and asks Historia to eat him. Again, he regains his senses after Historia, in an unexpected turn, chooses to side with him instead and boosts his willpower.
  • Heroic Build: His Titan form has it, and his actual body is pretty sculpted, too.
  • Heroic Lineage: Eren currently possesses the powers of the "Attack Titan," one of the original nine Titans, that he inherited from his father, Grisha, and his namesake Eren "Owl" Kruger.
  • Heroic Resolve: A necessary ingredient for transforming into his Titan form.
  • Heroic RRoD:
    • As he pushes his Titan Shifting ability to its limits, maintaining lucid control becomes more and more difficult, and can result in loss of consciousness at best, and Eren melding with his Titan body at worst.
    • After Eren overuses his new power he suffers an intense nosebleed.
  • Heroic Sacrifice: Sacrifices himself to save Armin during the Battle of Trost, though he manages to survive the experience.
    • Seeming pulls one again by losing his will to live and allowing Historia to claim her birthright by eating him. At the last moment, she decides to not go through with it and restores his determination.
  • Heroic Second Wind: At one point, it looks like he's down for the count, but then sees the same Titan that ate Thomas Wagner. He immediately gets the resolve to fight his way through several Titans to put it down.
    • In the anime, after Annie kicks his face in, Eren manages to get a second wind from his unshakable willpower and his desire to murder every last Titan.
    • While Hannes is getting eaten Eren is powerless to help (being unable to transform) and breaks down in tears. Mikasa snaps him out of it and he tries to take on the Titan that ate his mother and Hannes with his bare hands. Thanks to his power as the coordinate kicking in, Eren walks away victorious.
  • Heroic Self-Deprecation: At more than one point in the story so far, Eren's realized that he's made the wrong decision and people wound up dying as a result. While nobody blames him, as said "wrong choice" is more often than not a reasonable one with consequences that no one could have predicted, he still blames himself whenever this is the case and responds by flying into a murderous rage and slaughtering whoever is truly to blame.
    • After learning that he is incapable of hardening, Eren briefly questions if he is capable of shouldering humanity's hope and muses how powerless he still is.
    • Taken to new heights when he realizes that he was simply meant to be a vessel for the Reiss family, and for a moment, loses the will to live, calling himself "unnecessary". He quickly snaps out of it after some much needed pep talk from Historia.
  • Heroic Will Power: How he maintains control of said Titan form.
  • Hero Insurance: This is a Downplayed Trope. His fight with the Female Titan destroys a good part of Stohess district, and many of the buildings he destroys were not empty (his first attack notably throws her on a "church" where a bunch of Wall Cultists were praying). The reactions afterwards vary between blaming Erwin for the damage — since it was his plan — yet knowing that this was the only way to stop Annie once she had transformed. But nobody seems to blame Eren personally. Said damage is much more emphasized in the anime, though.
  • Hero with Bad Publicity: He is framed as an Omnicidal Maniac that is planning to destroy the world, in order to justify declaring war against Paradis. It doesn't help that he acknowledges he could be the bad guy, and he's willing to kill innocents in order to assassinate Willy Tybur.
  • Hero-Worshipper: Little Eren held the Survey Corps in the highest regard and aspired to join them one day.
  • He's Back: Crosses a Despair Event Horizon near the end of the Uprising arc, but manages to come back from it.
  • Heterosexual Life-Partners: With Armin, who's been one of his closest friends and allies for most of his life. In fact, Armin was Eren's Only Friend for quite some time before they met Mikasa.
  • He Who Fights Monsters:
    • Eren's Titan is a fiercer combatant than all other Titans including the other Titan Shifters. If anything, he's too fierce for his own good.
    • Years later, Eren's obsession with defeating his enemies and fighting for freedom has turned into a cruel man, turning against his friends and even ally with his half-brother. In addition to this, not only has Eren use the Titan Shifters' infiltration method against them, he uses the same threat against both enemies and friends alike (threaten to transform into a Titan if they do not listen to him).
  • Hidden Depths: Eren is a loyal friend and an enthusiastic person who offers his hand in help as much as he can. He is also surprisingly good at approaching the kinder side of the people he meets, making his friends and comrades staunchly defensive of him. His tendency to pick fights makes people initially antagonistic against him, though he only gets better with time.
  • Hidden in Plain Sight: The Living MacGuffin that everyone wants to obtain simply walked into Marley, disguised as a maimed and traumatized Returning War Vet. No one looks at him twice, allowing him to slip into the ghetto and create a convincing cover story.
  • High-Pressure Blood: Used for drama, whenever he bites his hand. Blood tends to splatter out around his teeth, even though such an injury generally wouldn't actually cause that to happen.
  • Hive Queen: Revealed in Chapter 50 to possess the ability to command Titans, causing them to attack his opponents. The other Shifters are shown to feel/sense the command, but are able to resist or ignore it.
  • Hope Bringer:
    • For many people. His Titan Shifting ability is a weapon that could permit them to eradicate Titans. Even more so after Chapter 50 when he awakens the power to control normal Titans.
    • Most citizens of Paradis view him as this, calling Eren their hero and savior, who can crush Marley and save Eldia. Eren's arrest by the Survey Cops incites outcry, with the citizens clamoring for his release and venting their anger on the government. There is even a vigilante group devoted to Eren, believing that he should be entrusted with the leadership of Eldia since he has what it takes to win.
  • Hope Spot: He encourages Falco to persevere by appealing to his uncertainty. He tells Falco that he'll either find hope or find hell, but the thing that Falco will regret the most is not knowing. This, of course, comes from Eren's own experiences and the ugly truths he uncovered on his own path. However, he then tricks Falco into sneaking a letter out for him, meaning the boy may no longer have a choice in the matter.
  • Horrifying Hero: He's unquestionably on humanity's side, but being a Titan Shifter horrifies everyone, understandably.
  • Hot-Blooded: Evident throughout the series, but particularly lampshaded in Chapter 34. Due to his perilous situation, he resolves to control his emotions. This state lasts for less than half the chapter.
    • Subverted after he inflitrates Marley. Eren has become more stoic, calculating and ruthless.
  • Hourglass Plot: Do many of the tropes on this page look familiar? They should. Many of them are on Reiner's page.
  • How Do I Shot Web?: Eren initially has difficulty activating his Titan-shifting power at his own free will. He eventually learns that only by having a deliberate goal in mind as he experiences pain does the transformation work.
  • How Much More Can He Take?: Pieck and Galliard are flabbergasted at how Eren is just transforming himself to his Titan form willy-nilly over and over again seemingly without regard for his stamina. Any other Titan Shifter would be pooped after three consecutive transformations while battling.
  • Humble Hero: Eren's come a long way since his brasher days at the story's beginning. He's no longer as Hot-Blooded, and has learned to adopt a more submissive behavior.
  • Humble Pie: His experiences during and following Trost greatly humble him, causing him to be more introspective and less rash.
  • Hunter of His Own Kind: Humanity's trump card against the Titans, and absolutely vital in taking on the other Titan Shifters.
  • Hunter of Monsters: Well, his last name is Yeager. He's the fourth type, one who seeks revenge against the Titans for his mother's death.
  • Hypocrite: Accuses Armin of being influenced by Bertolt's memories upon inheriting the Colossal Titan while ignoring that he himself carries the Attack Titan, the War-Hammer Titan, and the Founding Titan.
  • I Cannot Self-Terminate: In Chapter 65 of the manga while in the underground chamber in the Reiss chapel. After it's been revealed what happened to the Reiss family and what Eren has to do with it, Kenny Ackermann takes the gag off of an Bound and Gagged Eren and cuts open his forehead to allow him to get revenge, only to be surprised when Eren basically states how he never wanted any of this while sobbing and Eren begs Historia/Krista to eat him and set things right. For a moment it looks like she will, but she ultimately refuses.
  • Idiot Hero: Not precisely stupid, but lets his emotions get the better of him. The show deconstructs the typical shonen examples by showing the realistic consequence of rushing blindly on willpower alone, and thereby ignoring the plan that your military superiors have set up. The consequences are terrible for him and his team in Trost.
  • I Just Want to Be Free: Despises the fact that humanity is reduced to the state it is, going as far as to call the Walls "cages". Eren has always had these desires, however in Chapter 88, it is revealed that there is additional influence to this as the Attack Titan is a Titan that constantly moves forward and seeking freedom.
  • I Let Gwen Stacy Die: He blames himself thoroughly for the deaths of the Survey Corps elite squad. In Episode 24, when he's undergoing a major Heroic BSoD and his usual motivations (namely "kill all the Titans" and "humanity will be free") don't seem to be able to shake him out of it, he gets angry remembering their deaths and gradually regains his resolve via Unstoppable Rage.
  • I'll Kill You!: He says this to the Female Titan, though it can't hear him at the time, even threatening to eat it. In the anime, when he goes berserk fighting it he says that he'll destroy the entire world. Later on, to Reiner and Bertolt.
  • I'm a Humanitarian: While in Titan form, he eats Willy Tybur's body right after crushing him to death- presumably just in case he really was the War-Hammer Titan (he wasn't) He also ate Lady Tybur after finding out she was the real War-Hammer and attempted to eat Galliard immediately afterwards, suggesting he's planning to steal all of Marley's Titan powers.
  • In-Series Nickname: Amongst The 104th Trainee Corps he's known as "that Suicidal Bastard" ("Suicidal Maniac" in the dub) due to how eager he was to pick a fight with the Titans; Jean came up with the moniker, and is the only person who will say it to Eren's face. This comes up later on, when Armin bluffs the Female Titan by saying this nickname instead of "Eren" and figures out that she must be one of the Trainees to correctly guess who he was talking about.
  • It's All My Fault: At several points, he's forced to make choices that end up getting people killed. He hates himself for this and keeps holding himself solely responsible even when there was no feasible way he could've known the consequences.
  • It's Personal: For Reiner and Bertolt, the feeling is definitely not mutual (his feelings towards Annie are much more complex). They indirectly caused the death of his mother. Of course he won't forgive them.
    Eren: I'll do everything in my power... TO MAKE YOUR DEATHS AS EXCRUCIATING AS POSSIBLE.
    • He clearly hasn't forgotten Gabi's face since their last meeting in Liberio, and is quick to take "the brat who killed Sasha" hostage along with the rest of the Corps.

    J – O 
  • Jack-of-All-Stats: His skills at 3DMG are average. He is skilled at martial arts though and that helps a lot when you are a Titan Shifter. Also, his instructor notes that his sheer persistence and dedication to training allow him to surpass many others.
  • Japanese Politeness: Despite his Hot-Blooded personality and condescending tone in casual conversation, he always addresses his superiors politely and formally and he's not even Japanese.
  • Jerkass: After the Timeskip, he's become downright hostile and unpleasant to his former comrades, wasting no opportunity to tear them down whenever they try to talk to him (including Hange, Armin, and Mikasa). Ironically enough though, this is Inverted with his enemies, who he now displays a surprisingly calm and even attitude towards (a stark contrast to his original self). Like everything with Timeskip Eren, however, jury's still out on what these changes in behavior actually mean.
  • Jerkass Has a Point:
    • In Chapter 107, Eren berates Hange due to the fact that Historia was indeed treated like livestock in spite of all his efforts and worries for her well-being, and that no one was able to give him or Historia a better alternative to that route in the four years since diplomatic talks began with the Marleyan military rebel faction and other allied countries. He even states that his punishment is pointless, as being the holder of the War-Hammer Titan, he doesn't even have to break out of confinement to wreak havoc. As a result, Hange later laments not being able to give Eren an answer, and states that she might not have been the right person to take command of the Survey Corps in the first place.
    • During his venomous, hateful rant against Armin and Mikasa in chapter 112, Eren does make some pointsnote  that probably have at least some truth to them. At the very least, the evidence for Mikasa's attachment to him being unnatural does lean towards Eren's side, as she very clearly has shown time and time again in the past to go to irrational lengths to protect him (including instinctively pinning down Armin when he attempts to punch Eren in her defense). And due to the nature of Titan memories, he's also probably not wrong in believing that Bertolt's memories of home and lingering affection for Annie may be influencing Armin's judgement. However, he certainly didn't have to present these things to them like a cruel jackass, and his accusations of Armin losing himself possibly applies to Eren himself as well.
  • Jerk with a Heart of Gold: He has a habit of saying what's on his mind when he really shouldn't and his anger is horrifying, but he is ultimately a nice guy in casual conversation.
  • Jerk with a Heart of Jerk: Following the Time Skip, namely after he was imprisoned after his attack on Marley. Eren casually dismisses Mikasa's staunch loyalty as being a slave to her Ackerman heritage and telling that he's always hated her right to her face. He also claims that Bertolt's memories are hindering Armin's judgment and calls him useless for that. Armin lashes out at Eren but is instinctively pinned by Mikasa, partly proving Eren's point (as Mikasa doesn't intervene in their fight afterwards).
  • Kick the Morality Pet: In Chapter 112, the long-awaited reunion between the main trio takes a sharp turn when Eren begins heaping abuse on his childhood friends. His cruelty brings Mikasa to tears, and enrages Armin to the point of throwing punches. For bonus, Eren ends things by literally kicking Armin while he's down, and then has his followers take Mikasa and Armin prisoner at gunpoint. Like everything else with post-Time Skip Eren, his actual motivations for doing this remain highly suspect.
  • Kid Hero: He is 15 by the time of the battle of Trost.
  • Laser-Guided Amnesia: After his mother's death, Eren was supposedly injected with a mysterious serum by his father, but can't recall the details due to a side-effect of said serum. The serum is believed to have been what gave Eren his Titan-shifting powers. However, the serum didn't give him all of his powers as the Coordinate powers he received from eating his father, who had eaten the real person with Coordinate powers: Frieda Reiss, Krista/Historia's older half-sister.
  • Laser-Guided Tyke-Bomb: When they discover he is able to transform into a Titan, humans allow him to live so he can exterminate all Titans.
  • Last Lousy Point: He puts a brave face everywhere he goes, and will fight tooth and nail against anyone that looks at him funny... except Mikasa. He never expects her to kick his ass, and he turns into jello whenever she does it. It's fair to point out that he ultimately cannot not expect such things from a person that babies him like she does. As a matter of fact, Mikasa is the only character that warrants Eren to want to stop and talk it over before picking a fight, and it never works.
  • Leeroy Jenkins: During his first battle, Eren gets pissed upon seeing a Titan eat one of his comrades and charges madly into the fray. This gets nearly everyone with him killed. Ironically, the only time where he doesn't pull this leads to many people being killed by the Female Titan.
    • His basic tactic as a Titan when facing other Titans. It's a double edged sword because Eren has a limited amount of time as a Titan anyway and thanks to his Healing Factor and hand to hand training he can bring down dozens of them but is susceptible to overwhelming numbers.
  • Legacy Character: Invoked and played with. According to the theory of the ethereal pathways that connect all Eldians, and by hints given by Eren Kruger in Grisha's memories, it's strongly hinted that Eren Yeager was meant to be the Attack Titan, or that there was at least a certain predisposition for him to acquire the Titan power, especially due to the fact that Kruger was able to mention Mikasa and Armin to Grisha Yeager years before the children were born, heavily suggesting that Kruger might have been tapping into Eren Yeager's memories from the future.
  • Leitmotif: The first intro theme Guren no Yumiya (Crimson Bow and Arrow) is stated to be Eren's theme.
  • Lightning Bruiser: After having been a Glass Cannon in his Rogue Titan form for much of the time, he finally gains the ability to harden his skin and thus greatly neutralizes his biggest weakness.
  • Living Emotional Crutch: To Mikasa, in an odd fashion. Eren has been such an effective crutch that he doesn't even need to be alive for Mikasa to be supported, all she needs is her memory of him.
  • Long-Lost Relative: War Chief Zeke is Eren's older half-brother, born from Grisha's first marriage. He's also Eren's antithesis in just about every aspect.
  • Loss of Identity: Invoked. Because of the momentous memories of Eren Kruger and his father Grisha, Eren behaves like a somewhat different person than how he used to be. His demeanor is less belligerent, he is more cunning and calmer, and he is less given to smile. He is still Eren, but not only "Eren" anymore.
  • Lotus-Eater Machine: Briefly (compared to Ymir's experience) trapped in a weird dream state while trying to retake Trost. In his dream he has no memory of his mother dying and doesn't remember his desire to explore the world beyond the walls (which Armin is able to remind him of breaking the dream). While in this state he is very violent towards Mikasa and tries to kill her. It's later implied that all Titans experience this when they lose control.
  • Lovecraftian Superpower: His Titan-shifting in particular demonstrates the more horrifying aspects of the power.
  • MacGuffin Super Person: Just about every faction in the story aside from the Garrison wants to have custody of him (though Pixis goes along with Eren being put in the Survey Corps' custody). This is understandable, as he's the first known human capable of transforming into a Titan. Even when other Titan Shifters start pop up, they still see him as important enough to risk everything and abandon their plans to destroy the people within the Walls just to kidnap him. This is later revealed to be due to Eren also having the mysterious "Coordinate" power, which lets him control Titans.
  • Many Spirits Inside of One: According to Isayama, the memories and personalities of his Titan's previous hosts sometimes influence him. When prying into Falco's rival/crush on Gabi, he was being influenced by "someone else" and their memories.
  • The McCoy: The brashest, most emotionally-driven, and most eager to fight among the main trio, although he's quick on his feet and can think when it counts. He is also highly invested in doing what he feels is the right thing, which may not always be the best thing.
  • Meaningful Name: His surname, Yeager, is a transliteration of Jäger, which means Hunter in German.
  • Mind-Control Eyes: Implied during the conversation with Armin and Mikasa at the restaurant. His eyes have suddenly affected a similar disinterested and detached look as Frieda Reiss had at the Chapel when the Will of the First King took over.
  • More Than Mind Control: Implied Trope. Though it hasn't been confirmed, it's heavily hinted that Eren's behavior and decision-making might be actively being altered by a number of factors including the memories of his own father, and the Attack, Coordinate and even the War-Hammer Titans' influence; that is, not including Zeke's manipulations, which are an adittional extra-thick layer to his mind-cake.
  • The Mole: Infiltrates Marley's forces, and sneaks into Liberio as a soldier. The Irony is not lost on him.
  • Mundane Object Amazement: As noted under The World Is Just Awesome, Eren is amazed and flabbergasted that there might exist bodies of water so massive no merchant could ever empty it, or that there might be entire plains of ice or fields of sand.
  • My Greatest Failure: In spite of his efforts to keep Historia safe, the alliances that the Eldians of Paradis make with the Marleyan military rebels and the country of Hizuru involve perpetuating the old rule of the Kings of Eldia, which means that Historia has to produce an heir whether she likes it or not. Having exhausted the few alternatives they had (if any), the attack on Liberio is carried out and Historia is forced into pregnancy.
  • Neat Freak: Funnily enough, Levi's habits seem to have rubbed off on Eren, as he frantically insists to Jean and co. in Chapter 51 to make their cabin spotless- much to Jean's irritation. However, it's likely that a huge motivation for this is simply because he's terrified of Levi.
  • Never a Self-Made Woman: An inversion. Eren became one of the best hand-to-hand fighters thanks to training from Annie, which later becomes very significant when it allows him to overcome Reiner's advantage of size, strength, and armor.
  • Never Gets Drunk: According to Word of God, he's developed an incredibly high tolerance for alcohol. Which suggests that Eren's been hitting the bottle a lot in the last 4 years.
  • Never Got to Say Goodbye: His last conversation with his beloved mother Carla, prior to her untimely demise at the hands of the Titans, involved screaming at her. He later expresses frustration at himself for this.
  • Nice Job Breaking It, Hero!:
    • Reiner and Bertolt might have been captured without incident if Eren hadn't gone and mentioned their village at that particular moment. Instead, it inspires them to decide now is the time to make their move and leads Reiner to confess everything to Eren. It rapidly goes downhill from there.
    • Eren's rampage during the Festival causes a major divide within the Survey Corps, with even Armin and Mikasa looking upset with him. Levi has him arrested for his actions, and Hanji states his decision was a betrayal of his comrades. Taken even further, Jean informs Eren that he is directly responsible for Sasha's death.
  • Noodle Incident: After the Eldians meet with the nation of Hizuru, at some point, Eren met with Yelena in secret with the help of the New Eldian Empire faction of the Survey Corps. Having expressed his appreciation and love for his teammates before, Eren apparently makes a Face–Heel Turn as a result, and begins taking extremist actions unbeknownst to both the military and his teammates. As of Chapter 110, what transpired during this meeting with Yelena, what was discussed, and what made Eren take this position, is not quite known. Also, it's not entirely known whether he is indeed following Zeke's agenda as it is, as the New Eldian faction was quite against the Eldians of Liberio.
  • Not Afraid to Die: What sets him apart from many other recruits. When Eren fights, he has no time to let the prospect of of death get in his way, and, in spite of what his allies think of him, Eren has every intention of walking out of each fight alive. Best exemplified when he unhesitatingly rushes the Colossal Titan the moment it reappears, meanwhile everyone else is too stunned to even move.
  • Not Blood Siblings: With Mikasa, who was adopted by Grisha and Carla after the murder of her biological parents and she lived with them for about a year. Despite their closeness, he tends to view Mikasa as the Annoying Sibling due to her overprotective nature.
  • Not So Different:
    • Although their goals and personalities are very different, Eren and Annie share the same love for unarmed combat, and both sometimes show a disturbing sadistic streak. Also, Eren's Titan form is closest to Annie's in terms of fighting ability, and even copies some of her moves. Finally, both characters have a mysterious father figure implied to be connected to — or perhaps responsible for — their Titan-shifting abilities.
    • He is also shown to be this to Historia. Despite their apparent differences, they both share the fact that they are being used as tools to further the agendas of their fathers without regard to how they themselves feel.
    • With The Reveal that came at the end of the "Uprising" arc, it turns out that Eren has much in common with the Titans, and the Shifters. It's seems to have put a damper on his Black and White views of the world.
      Eren: What are we really fighting against..? Are Titans... really Humans... trapped in a nightmare..?
    • His thoughts about Reiner and Bertolt.
      Historia: What are you going to do... If we meet them again?
      Eren: ...(quietly) I must kill them.
      Historia: Do you want to kill them?
      Eren: ...I must... kill them.
    • Falco, much like Eren in his youth, is lagging behind his teammates and their main competitors happen to be girls that they very much care about and want to protect and are The Aces of their group (Gabi and Mikasa). He gives encouragement to Falco much like Reiner had done for him before, all while acting as a mole for the enemy.
    • Eren explicitly discusses this in the 100th chapter, acknowledging both his similarities to Reiner and the fact that Eldians on both sides of the conflict are simply ordinary people facing similar struggles.
  • Not So Stoic: Eren's stoic facade breaks when Sasha dies.
  • Oblivious to Love: He finds Mikasa's desire to keep him safe irritating and sees her as his annoying adopted sister.
    • Unlike his squadmates, he fails to grasp that Hitch may have feelings for Marlo.
  • Oh, Crap!:
    • He insults Rod Reiss's short height before realizing that Levi is right behind him.
    • During the audience at Queen Historia's court, he realizes that the Smiling Titan and Grisha's first wife Dina Fritz are one and the same and that was what triggered the Coordinate ability, the shock causing him to jump out of his chair. Immediately after that he realizes that if he reveals that connection between the Coordinate and the Royal Family, he might put Historia's life in danger because he would need royal blood in order to use the Coordinate correctly, meaning they might titanize her or otherwise put her in harm's way; this is because Historia purposely refused to eat Eren to gain the Coordinate, as if she did so, she would be subject to the Will of the King and restart the policy of isolationism and stagnation that they fought so hard to abolish (though she also is completely against eating Eren, a friend that is very dear to her). When he is reluctant to speak despite his outburst, Hange picks up on the fact that he realized something and dismisses it to Zackley as Eren acting up.
    • After being The Stoic for so long Eren gets a subtle one when Reiner gets back up in order to rescue Galliard from him. He clearly wasn't expecting Reiner to still have the willpower to fight and is perturbed that he lost his chance to eat the Jaws Titan.
  • Older and Wiser: Zig-zagged. While the young Eren was filled with righteous fury towards his foes, as an adult he no longer sees his enemies as monsters to be exterminated. Instead, he explains to Falco how people fight because they are pushed into it by their environment, other people, or their own vision of something beyond the horror of war. However, he deliberately goes against the Survey Corps' plan during their assault on Liberio, and his rash decision causes an otherwise-flawless operation to end up with several casualties, including Sasha. Hange lampshades this, saying that his actions were "suicidal" and the Survey Corps had to bail him out for them. In short, while Eren is much more composed and intelligent, he's no less reckless.
  • Old Soldier: Even though he's not "old" per se, Eren does show the grit and the grizzle associated with the trope. He had an early start, considering he was a Child Soldier.
  • O.O.C. Is Serious Business:
    • When Annie is finally revealed as the Female Titan, he does not (initially) react with the typical murderous rage he shows when Titans are around — he shows a surprising amount of compassion, and is actually willing to hear her out — he simply cannot bring himself to completely dehumanize her. This highlights just how deeply he's grown to respect her.
    • The only time he completely loses hope and is unable to use his rage to get back into the game is when he's unable to transform as the Smiling Titan bears down on him and Mikasa. He does not take it well
    • His lack of resistance to the prospect of being Eaten Alive in Chapter 65 briefly takes Historia aback.
    • Played for laughs in Chapter 70 when Jean gets up to his old tricks and throws a few sarcastic remarks in Eren's direction (complete with a hilarious Troll face)... and is a little disappointed when Eren doesn't take the bait.
    • After reading his father's journals, he starts showing some very odd behavior: scowling at nothing, muttering to himself, sudden outbursts, etc. Most disturbing of all he starts having Not Himself moments where he talks like a different person. The fact that he is seeing different memories from various people has probably not done his sanity any favours.
    • After the Time Skip, this is Played for Drama. Levi, Connie, and Mikasa all comment on how this "new" Eren isn't anything like the Eren they've known over the years. His actions and behavior towards his friends leaves them baffled, and likewise confuse the audience.
  • Order Versus Chaos: His obsession in gaining freedom using questionable methods puts him in the Chaos Neutral.
  • Our Hero Is Dead: Gets eaten by a Titan in Chapter 4. It starts to look like a case of Decoy Protagonist, except he's Not Quite Dead. He comes back A-OK in Chapter 9 as the Rogue Titan, who ignored any humans it came across and instead slaughtered every Titan it could find.
  • Out of Focus: Thanks to getting kidnapped again during the "Krista is Royalty" plotline, he goes several chapters without an appearance.
    • Happens again starting with chapter 91 as the story switches to Reiner's perspective off the island the story had taken place on up til that point, back at his homeland of Marley.

    P – S 
  • The Paragon: Invoked. He is poised as this by the military high command of the Eldians given the sheer importance of his contributions to the cause of humanity; as such, he starts being considered as the front and center of the war effort by both his followers and the common population. A problem arises with the fact that his cause and the military's begin straying from the other's path, especially when division starts appearing in the Eldian army, with a faction adopting a pro-war and pro-Eren narrative, causing the high command to be undermined as a result.
  • Partial Transformation: When lashing out at Hange over Historia being forced into motherhood by the government, his Titan Shifter facial ridges manifest and he not-so-subtly threatens to use his newly acquired War-Hammer Titan powers to break free and go on a rampage.
  • Pay Evil unto Evil: Prone to this when dealing with enemies he feels are "not human", such as the kidnappers from his childhood or the Titan Shifters.
  • Perpetual Frowner:
    • Eren is a master frowner to say the least. His life from age ten has done little favors to ameliorate this and his anger is something to behold. Still, Eren is a kinder person than what he appears to be.
    • After the Timeskip, Eren's facial expressions pretty much consist solely of a stoic, contemplative frown or a frown rooted in extreme anger. Easily Justified, however, considering the fairly miserable life of constant warfare he's trapped in.
  • Person of Mass Destruction: And no, we're not referring to his Shifting powers The Coordinate can be used to control all Titans, including the thousands of Colossal Titans that make up the Walls. In fact, this is what the First King threatened to do if his "paradise" was ever invaded; wake up the literal sleeping Giants and sic them on the rest of the world. It is perhaps fortunate that the Coordinate is particular about bloodlines, because if Eren had been able to do this before his Character Development...
  • Pet the Dog: He befriends Falco, and is relieved when the boy admits he probably won't be chosen as a Warrior. He offers encouragement and advice to the boy when he feels defeated over his training. Cruelly subverted later when it's revealed that Falco's letter deliveries were at least part of the reason Eren befriended him, and he later has no qualms nearly killing Falco as an incidental casualty.
  • Phlebotinum Girl: He possesses the Coordinate ability, which the king hopes to acquire by eating him.
  • Please Kill Me If It Satisfies You: After the truth about where his power came from is revealed, Eren loses the will to live and outright asks Historia to eat him. She doesn't, and instead gives him a good lecturing to restore his fighting spirit.
  • Plot Coupon: He is in possession of the key to the Yeager residence's basement, which is believed to hold a secret that may contribute to humanity's victory against the Titans. The basement in question, however, is still located in Titan-infested Wall Maria.
  • Plot Magnet: He is so important that many fans want him to get captured.
    • This is somewhat subverted later on when it is revealed that a lot of Eren's apparent importance comes from the result of a number of circumstances that just happened to come together. He actually has a brief moment of I Just Want to Be Special angst from this, before being righted again.
      Eren: The instructor was right. ...I wasn't special at all. It's just... that I was the son of a special man.
  • Power Copying: He's able to learn and effectively use one of Annie's moves after she used it against him. She's genuinely surprised when he uses it later that evening, and ends up teaching him her fighting style.
  • Power Echoes: During his rematch with the Female Titan in the anime, after she almost bashes his face in and takes off, Eren reaffirms his resolve to kill all Titans with his voice distorted and echoic.
  • Power High: Not so much from power itself, but simply from being able to kill Titans with ease. When he first regains consciousness after having emerged from his Titan body, he sleep-talks about wanting and being able to kill so many Titans with a creepy grin on his face.
  • The Power of Hate: What really motivates him is his desire to eradicate every Titan on the planet. Seeing as he needs a specific goal to transform, the desire to kill is actually is the trigger to many of his transformations. Even while in the stomach of a Titan, it is his insatiable rage that manifests his powers for the first time.
  • Pro-Human Transhuman: Determined to use his Titan powers for the sake of humanity.
  • Properly Paranoid: Before the attack of the Colossal Titan, Eren was always warning others that the Walls won't protect them forever. People would laugh at him and say he was crazy — Until that day...
  • Protagonist Journey to Villain: Played with, though exactly what is going on remains ambiguous. Over the last several months leading up to his attack on Liberio, he was secretly conspiring with Zeke's group and a rogue element within the military itself. Since being brought home, he has refused to explain himself to his old friends and even threatened them with his powers. As Paradis braces for a potential retaliation from the rest of the world for Eren's attack, his actions have also inspired a xenophobic movement that seeks to unseat the current government and restore the old Eldian Empire. With Commander Zackley's assassination coinciding with Eren breaking himself and his followers out of prison, the nation is a powder keg with Eren being set to oppose his former comrades.
  • Protagonist Title: His Titan form is the titular Shingeki no Kyojin. Somewhat less so in the English version, which has the Attack Titan (though a more accurate translation would be Advancing Titan) as the heroic Titan in Attack on Titan.
  • Protectorate: Under Mikasa's completely unwanted protection, and, later, the Survey Corps'.
  • Psycho for Hire: A heroic example. Having a job where you have to kill Titans perfectly suits a guy who craves exterminating them, no?
  • “The Reason You Suck” Speech:
    • An epic one in Chapter 19 and to Reiner during Chapter 43.
    • Delivers shockingly brutal ones to Armin and Mikasa of all people upon their reunion in chapter 112, explaining calmly and yet ferociously that he believes Armin has let Bertolt's memories make him "absolutely useless and soft". He then goes on to coldly dismiss Mikasa's feelings and explain that her devotion to him is nothing more than the result of experiments done on her bloodline long ago, calling her a "slave" and expressing that he's always hated her. He earns Armin's wrath for his troubles, though being bigger and stronger, he easily deals with him
  • Rebellious Spirit: His childhood was marked with constant battles with other children (and even adults in the Garrison), all the while calling people livestock for being content in their lives within the Walls. While he was Properly Paranoid, he continues to challenge social norms and accuse high-ranking military and government officials of being cowards.
  • Red Oni, Blue Oni: Hot-Blooded Red Oni to Mikasa's Emotionless Girl Blue.
  • Rejected Apology: Played With to "Denied Permission to Feel Remorse" in this case. Thanks to his rigid view of morality, when Reiner, the host of the Armored Titan, shows remorse for the destruction of Wall Maria and attempted destruction of Wall Rose, this only enrages Eren even further since he sees him as a monster who isn't allowed to feel any emotions.
  • Required Secondary Powers: Lampshaded in regards to his power as the Rogue Titan, as he doesn't have them. It's pointed out that Eren's strength is monstrous even by Titan standards, but his body is still relatively frail like any other Titan and can't handle the force of his own punches; he tends to break his arms and hands with every landed hit. He gets better much later on, as he acquires the ability to harden his flesh like Annie and Reiner.
  • Returning War Vet: While infiltrating Marley, Eren posed as a maimed and traumatized soldier returning to Liberio from Marley's Mid-East Alliance War.
  • Revenge: Eren has a personal, ever-growing list of people he seeks bloody vengeance for, and every name leads back to the Titans.
  • Roaring Rampage of Revenge: You could say his entire life is one. He always wanted to join the Survey Corps, but after the Titans killed his mother, he promised to kill them all.
    • Even before that, there was his first meeting with Mikasa. His father was her family's doctor, so they were the first ones to find out that Mikasa had been kidnapped and her parents murdered. He also found out where they were before the authorities did, and went there with a knife at the ready.
    • When Thomas dies during the Battle of Trost, Eren absolutely loses it and pursues the Titan who did it to avenge his friend. It nearly cost him his life. Thankfully, his Titan-shifting powers saved him.
    • He has his biggest one yet after finding out that some of his friends were the Titans responsible for all of his suffering.
  • Sanity Slippage: While nowhere as bad as the other Shifters Eren is in need of some serious therapy. Completely justified as he watched his mother get eaten and his home razed by the things that kept him caged from seeing the outside world, and later the identities of the Colossal, Armored and Female Titans are things that would need psychiatric help to deal with...
    • Best shown when 'dreaming' (actually remembering) his rampage after becoming the Rogue Titan for the first time with a Slasher Smile on his face. Armin's expression shows that he realizes just how far off the deep end his friend has gone.
    • It reaches a boil in Chapter 89, where the characters in his memories start mentioning things that they can't possibly know, like "The Owl" mentioning Mikasa and Armin, and Grisha going "who are Mikasa and Ermin" then "The Owl" going "I don't know. Whose memories are these anyway?"
  • Satanic Archetype: To the Marleyans, Eren (as the holder of the Coordinate) is effectively the leader of the Devils of Paradis, who himself usurped the "deity" of the Kings of the Walls to wage war on humanity with his hordes.
  • Saying Too Much: His restraint isn't that great even after some harsh lessons. At one point, he even mentally questions whether to keep his rant going or not during his trial but proceeds anyway. Bad idea.
  • The Scapegoat: The Tybur family's plan to destroy the Eldians living in Paradis Island is by publically revealing that King Karl Fritz, aka the First King of the Walls, was the one to end the Eldian Empire and saved the world. However that peace is now supposedly threatened by Eren because he stole the power the Founding Titan from King Fritz's descendants turning Eren into the face of the evil Eldians living behind the Walls. Judging Eren's actions against his own comrades since the attack on Liberio hint that the Tyburs were not entirely wrong about Eren.
  • Scarily Competent Tracker: Without bloodhounds, gps, tracking devices, cameras, or surveillance equipment of any kind, he was able to track down Mikasa's kidnappers and Mikasa herself, alone, and at age nine. How he was able to do this is not shown.
  • Schmuck Bait: Does this to Reiner when he prepares to transport the currently hand-less Eren to his hometown:
    Reiner: ... We're leaving now. Eren, don't try to resist.
  • Screaming Warrior: Eren is quite prone to this. Especially in Titan form. Mikasa even says that his roar embodies humanity's collective rage.
  • Screw the Rules, I'm Doing What's Right!: He insists that if he had gone to get help after tracking down Mikasa's kidnappers they would have been too late (which is likely true). With only himself and a knife there, he did the only thing he could to save her.
  • Self-Harm: How Eren shifts to his Titan form; he usually bites his hand. Eren himself does not understand how he knew doing so would trigger the change. It should be noted that the bite alone isn't enough to do it (as he found out during a Survey Corps experiment), he also needs a specific impetus besides "turn into a Titan" such as "block that cannon shell".
  • Self-Made Orphan: It's revealed that Grisha intentionally fed himself to Eren, so that his son would gain the ability to control his Titan form.
  • Sensitive Guy and Manly Man: The manly man to Armin's sensitive guy.
  • Shame If Something Happened: The place Eren chose to confront Reiner at was not random. When Reiner doesn't move after Eren tells him to take a seat, he (Eren) notes that there are a lot of people settling in to watch the Tybur's Play... right above them. He points up while saying the last part, letting Reiner see that there's a fresh gash on his hand, conveying the unspoken threat without immediately alerting Falco. He later makes good on this threat in order to kill Willy Tybur.
  • Shell-Shocked Veteran: Played with. Though he's faking it to remain in the hospital, it's fair to point out that he's not that far off from being one considering what he had to go through in Paradis.
  • Shirtless Scene:
    • In Chapter 53, Eren is given the honor of being the first shirtless scene in the series. It is combined with Fan Disservice, thanks to his face being melted off at the time.
    • In Chapter 61, his captors seem to have taken the time to remove his shirt before chaining him up.
  • Sibling Yin-Yang: Compared to his adopted sister, who's The Stoic, The Lancer, and an Emotionless Girl.
  • Slasher Smile: He sported one while still asleep after his first transformation into a Titan, thinking his memories in that form were a dream. He also gets an epic one when he's one strike from slaying the Female Titan in his Titan form, though his human form is the one doing the smiling.
  • Spanner in the Works: For the Warriors; As Reiner put it, he is "the worst possible person" to possess the Coordinate. There are a number of good reasons for this:
    • Eren is too much against them for them to sway him over, adding to the fact that he's a relentless and incredibly stubborn person to begin with;
    • Reiner and Bertolt respect him and care too much about him for them to subject Eren to an Undignified Death just to gain the Coordinate and their boss, Zeke, also won't go that route since Eren is his Half-brother;
    • Eren has the complete backing of the Survey Corps and he is the flag-carrier for humanity's plight;
    • Eren might not be able to use the Coordinate correctly, especially considering that he is neither a Reiss nor a Fritz;
    • There's also the possibility that Zeke might not be so keen to kill his own brother just to gain the Coordinate;
    • The most serious reason: his anger; Eren is well known for his hatred towards Titans/Shifters, and definitely not the kind of person you'd want holding an ability that could potentially wipe you all out.
    • Then there's also the fact that Eren holds the Attack Titan too, which happens to be a fighting, kicking, and biting powerhouse, and was purposely created to fight to the death for its freedom, making it a bitch to retrieve from its holder. Not even Frieda Reiss using the Progenitor Titan was able to overpower Grisha's Attack Titan, and she was a few hairs short of being a physical god. As it turned out, Annie, Reiner, and Bertolt were collectively unable to wrest it from Eren... who holds the Coordinate now, too. Crap.
    • Almost as serious is that, as revealed by Rod Reiss and by Grishia's journals and memories, the Coordinate doesn't just affect Titans; it has power over all the Eldians, namely with the ability to see and reshape their memories at will... and it's in the hands of a guy who's defining trait is having rage issues so intense that his nickname is suicidal bastard. If someone like that had a free pass to your mind, you'd probably be wary too, good intentions or not.
    • As a matter of fact, the revelation of Eren being a Titan Shifter derailed their plans in the first place, as by choosing to separate, Reiner and Bertolt left Annie to fend for herself on her own at the MPs. When push came to shove, Annie was found out without any support from her fellow Warriors because they decided to tail Eren instead. Annie's discovery in turn raised suspicion on Reiner and Bertolt themselves, making original split about the worse move they could have pulled. Good job, guys!
  • Spare to the Throne: Invoked and played with. Curiously enough, Eren is considerably removed from the definition of the trope for someone actually associated to it. His father Grisha was married to Dina Fritz, the last remaining member of the Eldian Royal Family that stayed in Marley, making Grisha a royal by marriage only (and not by blood); this separates Eren by two degrees, as he's Grisha's son from his second marriage. Also, Eren carries the Coordinate, the power of the Progenitor Titan that basically makes the King of the Eldians "King" in the first place... only that Eren is not a royal himself and cannot use it for crap unless he comes in contact with a royal, or said royal devours him. As a matter of fact, Eren has made a point not to mention anything regarding Dina to the Military establishment at the Walls because this might put Historia's life in danger, as Dina herself was Titanized precisely to prevent the parties in question to misuse her royal blood, and Historia is a royal, too.
  • Spell My Name with an "S": The official translation gives his family name as Yeager, which is the Anglicized version of Jäger/Jaeger. However, many translations (most notably Funimation's) use Jaeger as his surname.
  • Spotting the Thread: Invoked and subverted. When he first sneaks into Liberio, he is using the armband that identifies him as an Eldian on the wrong arm. Falco notices, but assumes the error to have happened due to war-induced trauma and puts it on the correct arm for him. Overall, Eren is not found out, even after telling Falco that he was faking his trauma. Another thread that Falco doesn't catch until it's too late is that if Eren met Reiner more than four years ago, he most likely did so while Reiner was on the island of Peradis, meaning that he's an Eldian and Reiner's enemy.
  • Spring Cleaning Fever: Eren is shown to thoroughly clean any new place he winds up in, not because he likes cleaning, but because of his experience with Levi.
  • The Stoic: Eren's most notable change is his temperament. In stark contrast to his old self, he's become a very withdrawn and calculating individual.
  • Strong Family Resemblance: His face is almost identical to his mother's. Curiously, his half-brother Zeke looks exactly like their father Grisha. After the Time Skip he still bears a striking resemblance to his mother, but Isayama states that he's starting to more heavily resemble his father as he matures.
  • Supernatural Gold Eyes: His eyes are sometimes colored this way in the manga, to emphasize his unusual abilities.
  • Super-Powered Evil Side: Initially, he is unable to control his Titan form and viciously attacks Mikasa. Armin manages to get through to him, and he's since learned how to control himself. In the anime, he goes berserk a second time while fighting the Female Titan, proclaiming he'll destroy the world and nearly eating Annie, only to be stopped by the sight of her crying.
  • Super Serum: Got his powers after Grisha's injection. But not all of them.
  • Super Soldier: His Titan powers have the potential to make him one, and he is treated as humanity's trump card. When announcing the plan to reclaim Trost, Pixis invokes this trope as a cover story to explain away Eren's powers to the masses — stating that he is the result of a secret government experiment to create a Super Soldier.
  • Survival Mantra: "FIGHT! FIGHT! FIGHT! FIGHT! FIGHT! FIGHT! FIGHT! FIGHT! FIGHT!!"
  • Sword over Head: In the anime adaptation, Eren, while in a murderous craze, has the opportunity to either capture or outright finish off Annie during their fight, but he instead hesitates, allowing Annie to crystalize herself.
  • Sympathetic Murder Backstory: Played with. He once murdered two men to rescue Mikasa, but this is later used by the Military Police Brigade to paint him as dangerous.
  • Sympathy for the Devil: His confrontation with Reiner does not go as anyone expected, having learned the truth about the Warriors. Eren expresses understanding and even sympathy for them, recognizing them as children that were lied to their entire lives and then tasked with (supposedly) saving the entire world. He acknowledges them as victims of their circumstances, even telling Reiner that he understands now how much they must have suffered the entire time. Reiner tries to reject Eren's sympathy, insisting that he was to blame for everything and begging for death. However, this sympathy and understanding doesn't stop Eren from doing to Reiner's hometown what Reiner did to his.

    T – Z 
  • Teeth Flying: During his trial, Levi kicks him so hard in the face that a tooth comes flying out immediately- although, thanks to his Healing Factor, is grows back in a few minutes. This also tends to happen to him in his Titan form a lot, as he often loses several teeth every time he takes a punch to the face from a fellow shifter. Probably a natural consequence of his tendency to fight with his jaw wide open while screaming (though to be fair, his Titan's teeth are exposed even when he's not yelling due to its lack of lips).
  • Tempting Fate:
    • Eren spends the first episode consistently telling everyone he knows that the Titans could breach the walls at any moment despite them having been kept out for the last 100 years. So, of course, guess what happens before the day is even over?
    • After graduating, Eren says something along the lines of "Now we'll be ready if the Titans attack today!" Needless to say, they weren't.
  • Then Let Me Be Evil: When Willy Tybur announces him as the enemy of humanity and declares war on him and the Devils of Paradis, Eren tells Reiner that he might as well answer as such, if that's what they want. He proceeds to transform, destroying the building over him and killing hundreds of innocents.
  • This Is Wrong on So Many Levels: Invoked. Connie is furious at the fact that Eren laughed when Sasha died. This is so blatant, so deeply offending, and so opposed to his previous declaration of love towards his friends that Mikasa falls short on trying to defend Eren.
  • Thousand-Yard Stare: As he sees the Titan that killed his mother five years ago slowly approaching him in Chapter 49.
  • Throw the Dog a Bone: In Chapter 41, Eren finally gets to kill a Titan (as a human) just like he's always wanted. Notably, this doesn't have any real story importance and he's promptly told to step back.
  • Token Super: Eren is the only human member of the Survey Corps who can turn into a Titan. This makes him the trump card of the military defending the town against Titan attacks.
  • Took a Level in Badass: Twice. The first was awakening his Titan Shifter powers, and the second time was awakening his "Coordinate" power, which allows him to command all normal Titans.
    • In Chapter 66, Eren upgrades his Titan by eating a serum labelled "Armored" after choosing to act and fight against Rod Reiss's Titan.
  • Took a Level in Jerkass: As an adult, Eren has become a cold and ruthless person fully willing to Kick the Dog to further his unknown goals. This includes manipulating vulnerable children, causing his own grandfather to suffer a breakdown, and viciously tearing down Mikasa and Armin emotionally.
  • Too Spicy for Yog-Sothoth: He gets eaten, then Titan-shifts for the first time within the Titan's stomach. The results of an unintentional Eat Me are not pretty.
  • Touch Telepathy: A minor example, but the memories he inherited from his titan powers tend to spring up when he touches Historia. Though they sometimes show up without being in physical contact, the most clear ones seems to appear when he touches her.
  • Tragic Keepsake: In the Attack on Titan 2 canon, he keeps Kare's sketchbook/journal following the latter's Heroic Sacrifice to save him and the rest of the Survey Corps recruits in the game's epilogue level.
  • Tranquil Fury:
    • Eren remains calm and in control during the confrontation with Reiner, probably to keep from alarming Falco, and even shows surprising empathy at times. But it's also clear that he has some mad left over. When Reiner didn't move after he was told to sit, Eren made a subtle threat against the dozens of civilians in the building above them, and showed that he'd already slit his hand in preparation to transform. Later on, when Reiner worked up the nerve to ask a question, he shot it down with some choice words.
    • This seems to be his new go-to method of expressing his anger after the Timeskip in general. Despite his calm tone, he's very clearly angry with how Armin has turned out these past few years, and he ruthlessly tears down his attachment to Annie and accuses him of letting Bertolt's memories turn him "soft" and "absolutely useless".
  • Trapped in Villainy: Invoked, and overlapping with This Is Wrong on So Many Levels. Eren berates Hange, and thus the military junta, for forcing him into this and then acting high and mighty, as if they hadn't strong-armed him through their inaction regarding the prospect of Historia being forced to produce heirs by following Zeke's plans for the Paradian Eldians and their allies. Eren has had to attack Liberio, killing hundreds and wreaking havoc, stating that at the very least he was able to achieve something by obtaining the War-Hammer Titan rather than achieving jack shit like they have.
  • Trauma-Induced Amnesia:
    • The gap in Eren's childhood memories is revealed to be the result of him suppressing the memories of his father's death.
    • He's faking Amnesia to remain committed to the veterans' hospital, and admits as such to Falco.
  • Traumatic Superpower Awakening: The first time he shifts into Titan mode is inside another Titan's stomach with 2 limbs missing, screaming that he will kill every last Titan. This kid does not give up.
    • Awakens his ability as the "Coordinate" after Hannes' death, allowing him to command normal Titans.
  • Troubling Unchildlike Behavior: Most normal youths his age don't express the degree of bloodcurdling fury Eren displays. It's a little scary.
    • As a child, he killed two grown men to save a kidnapped Mikasa and showed no remorse.
  • True Companions: He, Mikasa, and Armin are this, being close-knit childhood friends who have risked their lives for each other on many occasions while in the military. That said, after the Time Skip, Eren's personality shift and cruelty toward his friensd are straining their bonds.
  • The Unchosen One: Eren eventually finds out that he only gained his powers because his father ate Historia's sister Frieda and then fed himself to Eren. Learning from Rod Reiss that he was never special and that (according to him) he was actively holding humanity back broke him to the point that he was willing to allow Historia to eat him and regain the Coordinate.
  • Undying Loyalty: Even unconsciously, he will protect Mikasa and Armin. It's a fundamental part of who he is.
  • The Unfettered: Post Time Skip Eren has now completely embraced his darker tendencies in order to end the war with Marley once and for all coldly transforming into his Titan Form in order to kill Willy Tyber undeterred by the amount of collateral damage or innocent civilians he killed in order to do so. This is in stark contrast to rest of the 104th's (except Floch) who try to limit their attacks to just the soldiers when possible and look saddened when they are sometimes forced to kill innocent people.
    Eren: I will keep moving forward... until the day I destroy the Enemy.
  • The Un-Reveal: It's not quite known how Eren never manifested his Titan powers for years on end after his father imbued him with the Attack Titan, especially considering that he is such a willful and belligerent person to begin with. However, prior to Trost, Eren had never experienced such physical trauma as he did when he was devoured by the Bearded Titan. After the dust had settled, even the mere act of trying to grab a spoon could trigger Titanization on him.
  • Unscrupulous Hero: He may be a Horrifying Hero and his Titan Shifter form causes a lot of destruction, but it's that same power that makes him one of humanity's biggest Hope Bringers.
  • Unstoppable Rage: His rage is a terrifying thing. Annie is noticeably frightened at several points during their battles, and during the mission to capture her, she abandons her mission to kidnap Eren (a thought that terrifies her comrades) and attempts to scale Wall Sina with her bare hands once he comes out swinging.
    • This is made even more apparent in the anime, where An Arm and a Leg have been broken off of his body in the second fight between him and Annie, and he's set aflame, he comes out running and crushes her skull. Damn.
    • After getting his arm and leg bitten off and while in the gut of a Titan he takes a moment to freak out before declaring that he WILL murder every last Titan.
  • The Usurper: Willy Tybur publicly poises Eren as such, being the holder of the Coordinate his father Grisha appropriated from their rightful holders, the Eldian Royal Family. In Paradis, his followers poise him too as the rightful leader of the Eldians against the military junta under Historia, and also against the foreign enemies of the Eldians.
  • Vengeance Feels Empty: In Chapter 84, Eren finally gives Bertolt the excruciating death he promised him by having him get eaten by a Titanized Armin in order to steal his Titan-shifting abilities. However, Bertolt's final moments consisted of screaming, crying, and begging anyone to come and save him, no different than any other person caught in a Titan's grasp. Eren clearly doesn't look even remotely happy about it, despite everything that Bertolt has done.
  • Vigilante Man: He hunted down and killed human traffickers, taking the law into his own hands. That he was a child at the time and the brutality of his actions left the authorities shaken.
  • Villain Protagonist: Degenerates into this after the Time Skip, to the point of casually murdering women and children in his attempts against Marley, and verbally abusing Mikasa and Armin.
  • Villain with Good Publicity: Eren enjoys strong support of the Paradis public, hailed as the messiah who will usher a new era for the Eldian empire. They are aware that Eren has killed Marleyan civilians, but they justify that Marley has done the same to other nations. Eren was merely giving them a taste of their own medicine. Also Eren has taken the government and military hostage, and people support him because the government was too indecisive and slow.
  • War Is Hell: He explicitly calls it this while talking with Falco, stating no one would want to fight if they knew ahead of time how it would destroy them.
  • Watching Troy Burn: He, Mikasa and Armin had to evacuate from Shiganshina, the first district to fall into Titan hands after a hundred years of volatile peace. Coupled with the loss of his mother, his response was to swear revenge.
  • We Meet Again: To the Colossal Titan:
    Eren: Hey, there....it's been five years.
  • We Will Meet Again: Once the Survey Corps are forced to leave Liberio after their attack Eren tells Reiner that the two of them will meet once more on the battlefield.
  • What the Hell, Hero?: Several characters call him out on his unwillingness to fight Annie once she's revealed as the Female-type because of the high death toll the unchecked rampage causes. In the anime version, later, Armin calls him out on his seconds-long hesitancy to capture her, which lead to Annie encasing herself in her Crystal Prison.
    • Mikasa admonishes him for carrying out the attack on Liberio, killing hundreds of innocent men, women and children.
    • Eren himself berates Hange for not finding an alternative to Historia's role in the negotiations with the rebel faction, which involves her resuming the rule of the Kings of Eldia and forcefully producing an heir. As such, with the time running out, Eren is forced to attack Liberio and Historia is forced into pregnancy, with no one offering even a slight glimpse of a way out.
  • What You Are in the Dark: Listening to Willy Tybur's expository speech, Eren notes that he understands exactly how Reiner felt and that he understands that the people of Marley are just people who have been brainwashed by years of propaganda... but this doesn't stop him from turning into the Attack Titan, bursting out of an occupied building to assassinate Willy Tybur.
  • Wide-Eyed Idealist: He is pretty idealistic, thinking humanity could still beat the Titans. And believing no matter how many times the Survey Corps fails, they at least bring back information mankind can use.
  • Wild Card:
    • It's implied that Eren acted without the full approval of the military command back at Paradis in order to strong-arm the Survey Corps into assisting him at Liberio. It does appear that the Survey Corps had drafted plans for the invasion going by their strategic movements during the battle at Liberio, but were still weighing on the risks by the time Eren set his foot in Marley's borders. Chapter 105 confirms Eren acted without approval from the Survey Corps, causing much of their plans to go awry.
    • In Chapter 108, his 104th friends speculate that Eren might not be operating based on their well-being anymore, even discussing the possibility that they would have to allow him to be eaten should he be proven treacherous.
    • Played with. Upon his unilateral and unauthorized attack on Liberio, Eren is no longer playing for the Eldian establishment anymore, escaping from custody and later capturing the Survey Corps with the troops that he swayed to his side. While the military and the Corps speculate that Eren is being manipulated by Zeke, judging by the strong anti-Marley sentiment of his troops, and by the fact that Eren himself is still vocal about referring to the Warriors as the "enemy", the possibility that Eren was completely swayed by Zeke is just as iffy as the rest of his actions.
  • The World Is Just Awesome: In-universe, it's hearing about the fascinating and weird aspects of the outside world like never ending pools of water, entire fields of ice and sand, and burning water that drive Eren to want to leave the safety of the Walls. By the time of the main story, it's the other part of his raison d'etre aside from murdering every single Titan: Eren wants to venture out into the world simply because it is the awe-inspiring world he was born into.
  • Worthy Opponent: Reiner, Bertolt, and Annie genuinely respect and seem to care for him, regardless of circumstances requiring that they are enemies.
  • Would Hurt a Child: While he isn't actively seeking to harm children, he accepts the possibility that they will die as a result of his actions. Several are killed when he transforms underneath an occupied apartment building, and more die during the battle between Eren and the War Hammer. He also knowingly endangers Falco, manipulating him in a manner that will get his entire family executed if discovered and later transforms with Falco standing close to him.
  • Would Hit a Girl:
    • He has no problem headbutting with Mikasa.
    • He punched Annie when he was fighting with her in titan form.
  • You Are What You Hate:
    • The first variation—he genuinely did not know about his Titan-shifting capabilities. Yet once he gets over the initial shock, he seems to take it in stride for the most part, and wants to use his Titan form for the betterment of humanity.
    • Though it's hinted in previous chapters, in Chapter 112 it's implied that Eren has fallen to the Attack Titan's will as a relentless seeker of freedom, betraying the Eldian military, his comrades and his best friends, due to the fact that they have become "slaves" in his mind. It goes to show that Eren Kruger's statement to Grisha was not only true, but was also a warning: the Attack Titan will always seek to be free.
      • In the same vein, Eren lectures Armin about the role of memories in forming a person's identity and how Bertolt's memories are influencing Armin. However, Eren doesn't bring up how the memories of the people who have become a part of him (Grisha, Kruger, Frieda Reiss, Lady Tybur etc.) are influencing him.
  • You Are Worth Hell: While facing seemingly certain death together, Eren has declared that everything he's done for Mikasa he'd be willing to do all over again.
  • You Killed My Father: Drops this on Bertolt in Chapter 46, telling him that a chunk of Wall Maria landed on his house, breaking his mother's legs and leaving her unable to run. The seemingly-cold response he gets only infuriates him further, and Eren vows to kill him as slowly and painfully as possible. He eventually delivers on that promise in Chapter 84 by feeding Bertolt to a Titinized Armin, though by that point he finds no satisfaction in doing so.
  • You Monster!: His reaction upon discovering Reiner and Bertolt's true identities, stating that he wants to puke. He later delivers a screaming rant to Reiner, calling him an inhuman monster with no right to feel guilt over his actions.
  • Younger Than They Look: After the Time Skip, while he doesn't look old per-se (and is, in fact, as fresh-faced and Bishōnen as ever), he has a very mature and world-weary look to him that makes it hard to believe he's still just 19 years old. Being a Child Soldier in a cruel world can have that effect on a person it seems.
  • Your Answer to Everything: Annihilating all of the Titans.
  • Your Days Are Numbered: As revealed in Chapter 88, anyone who inherits one of the nine original Titans abilities die thirteen years after inheriting due to Ymir Fritz dying thirteen years after she obtained her powers. As such Eren has approximately eight years left to live, so long as the statement is true. Chapter 91 shortened that to Four.
  • You Will Know What to Do: The last time they saw each other, Grisha told him that the only way to make full use of a certain "power" was to take back Wall Maria and find the "truth" in the basement of their old home. After Eren finally gets to the basement and learns about Marley and the rest of the world, his personality changes drastically to the point where no one recognizes him anymore presumably due to acquiring the necessary memories to complete his father's mission.
