Attack on Titan is critically acclaimed and one of the most popular anime series of all time. Based on the manga by Hajime Isayama, the Attack on Titan anime launched in 2013 and looks primed to end in 2023.
In the story’s world, enormous man-eating humanoid creatures called Titans threaten humanity. To survive, human society took refuge inside cities surrounded by three enormous walls that protect them from the Titans. This civilization fights back against the Titans with grappling hooks and sharp blades, which allow the military to swing around their assailants and slice open their necks, killing them.
Both the anime and the manga follow Eren Yeager, along with his friends and comrades Mikasa Ackerman and Armin Arlert, who are a part of the Survey Corps branch of the military. Other main characters include leaders such as Levi Ackerman, Erwin Smith, and Hange Zoe. Eventually, all of these main characters meet Zeke Yeager, Eren’s half-brother (who is not a part of the Survey Corps).
Throughout its run, Attack on Titan introduces plenty of fantastic characters who have gone on to leave a significant impact on the franchise’s fanbase. Let’s take a look at these AoT characters’ ages, heights, and birthdays.
Although they will be kept to a minimum, spoilers will not be completely avoidable. Please bear that in mind if you are not up to date with the anime.
Attack On Titan Statistics Chart
Attack on Titan’s roster of (important) characters is quite extensive, so much so that this summary has ballooned to over 30 entries.
In order to make the information as readily accessible as possible, the following table has been constructed to provide a breakdown of each Attack on Titan character’s age, birthday, and height. How tall is Levi Ackerman? When is Eren Yeager’s birthday?
¹ Erwin Smith’s age has not been revealed, but he was in grade school when his father died around Year 825. By Year 850, Erwin is the Survey Corps’ commander and, presumably, a few years older than Levi. Therefore, he should be in his late 30s.
² Based on player theories and speculation.
³ As a young teenager, Ymir transformed into a Titan and then spent the next 60 years stuck in that form. She changed back to human in the Year 845; consequently, she must be in her late teens by 850.
⁴ An approximation based on the character being part of the 104th Training Corps.
⁵ Introduced in Year 854.
⁶ In the Year 829, Kenny was a young man (and serial killer), so it can be assumed that he was around 20 at this point.
Eren Yeager
Eren Yeager is the main protagonist of Attack on Titan, and he is introduced as a rather straightforward character. In the anime’s pilot, Eren watches helplessly as his mother is devoured by a Titan; naturally, the boy vows to destroy every Titan to ever set foot on the planet. To achieve this goal, Eren enrolls in the military as part of the 104th Training Corps and eventually joins the Survey Corps.
Eren undergoes a great deal of development throughout the anime, growing into a far more nuanced character by Attack on Titan’s season 3. Eren’s journey is one defined by an unrelenting drive for not only vengeance but to find purpose in the pain he and everyone else has experienced. He desperately wants to make all that suffering mean something, that it ultimately resulted in a better world. Eren is smart, manipulative, charismatic, and committed.
Mikasa Ackerman
Eren’s right-hand partner, Mikasa Ackerman is nearly always by the protagonist’s side, especially in the anime. Strong, fearless when up against Titans, and quiet, Mikasa is among the last living members of the Ackerman clan; unfortunately, this makes her a target. At the age of 9, traffickers killed Mikasa’s parents and might have kidnaped the girl if Eren did not show up to rescue her. Mikasa immediately repaid the favor.
Mikasa’s personality is directly molded by her relationship with Eren, as she reflects her friend’s brash and direct nature. Despite her physical abilities ranking among the best in this universe, Mikasa’s obsessive devotion to Eren gives her a huge blind spot that Attack on Titan challenges more and more as the story progresses.
Armin Arlert
Armin Arlert completes Attack on Titan’s main trinity, standing alongside Eren and Mikasa. Typically taking a backseat to the other characters, Armin doesn’t fully come into his own until around season 3; after this point, the character’s strategic and analytic mind starts to really shine through.
Armin’s soft-spoken nature matches well with Eren’s aggression, with the former occasionally serving as the voice of reason. As the anime has progressed, this character has been forced to take on a leadership role due to his analytical mind and willingness to explore all avenues when faced with a dilemma. Despite experiencing a lot of hardship throughout the story, Armin has not changed all that significantly from his initial depiction, at least nowhere near as much as Eren.
Levi Ackerman
Arguably the anime’s most beloved character, Levi is one of the strongest fighters in the Survey Corps and serves as a squad captain. Willing to take on an army of Titans if necessary, Levi doesn’t hesitate to put it all on the line for the sake of safeguarding human life. This goes beyond Titans, as Levi’s hatred for Kenny Ackerman, a serial killer, is just as intense.
Vicious in combat and distant outside it, Levi is a blood-soaked soldier who carries the weight of the world on his shoulders because he knows most people cannot handle the burden. Attack on Titan has gradually revealed Levi’s background, showing that he started as a criminal before eventually joining the Survey Corps. Levi is the type of person who only follows orders from people he respects; that said, he is generally quite empathetic.
Erwin Smith
The Survey Corps’ 13th commander, Erwin Smith takes on a primarily behind-the-scenes role for large chunks of the anime; however, he casts a wide shadow over a lot of the story. Highly respected by Levi and Hange Zoë, Erwin constantly struggles internally with his desire to satisfy his curiosity about the state of the world and his role to preserve humanity’s future.
Erwin’s complexity doesn’t fully reveal itself until very late in the character’s story, but he becomes a prominent figure towards the end of season 3. In the public eye, the commander presents an unshakable and controlled front; he is the leader humanity needs. Behind closed doors, Erwin is far more unsure about himself, questioning not only his actions’ validity but also their righteousness.
Reiner Braun
Initially coming across as something of a big brother to Eren and company, Reiner eventually reveals that he has been hiding a dark secret. A spy sent to infiltrate humanity, Reiner joins the Survey Corps in an attempt to get closer to discovering the Founding Titan.
Reiner’s reveal marks a high point in Attack on Titan, a twist so unexpected and expertly delivered that it sent shockwaves across the anime world. Reiner’s dual life caused him to develop various mental problems, as he lost himself within the personality he created. By season 4, he is a broken individual who does not fully feel like he belongs anywhere. Reiner’s backstory does a lot to flesh out his personality and psychological struggles, turning what could have been an “evil all along” type character into a tragic figure haunted by his past despite mostly believing that he did what needed to be done.
Bertolt Hoover
Reiner’s partner, Bertolt slips into the background during Attack on Titan’s first season, coming across as a rather meek and unassuming individual. Once it is revealed that Bertolt is the Colossal Titan, he becomes more aggressive and appears less conflicted about the situation than Reiner.
Although a villain from the perspective of Eren and the other character, Bertolt seldom falters in his belief that his actions are justified. Attack on Titan’s brilliance comes down to its desire to showcase the reasoning behind each party’s actions, presenting almost nobody as purely evil or indisputably good.
Zeke Yeager
Eren’s half-brother, Zeke is introduced as the Beast Titan and the captain of Marley’s Warrior Unit. Despite his allegiance to Marley, Zeke is not to be trusted and is primarily driven by his desire to eliminate the Subjects of Ymir, which are all the descendants of Ymir Fritz.
Highly intelligent, brutal, nihilistic, and manipulative, Zeke is a threat whether in his Beast Titan form or not, and nobody is really safe from his wrath. Zeke’s relationship with Eren, his half-brother, introduces different facades to both characters.
Hange Zoë
While not explored as thoroughly as the likes of Levi or Reiner, Hange Zoë is still one of Attack on Titan’s best secondary characters. Whether providing some much-needed comedy relief during the early parts of the anime or demonstrating a willingness to commit atrocities in pursuit of their greater good, Hange is enigmatic and magnetic.
Hange has a close relationship with Levi stemming from their shared time in the Survey Corps. As the story progresses, Hange becomes a more serious and grim figure as they are forced to take on more authoritative roles in Attack on Titan.
Historia Reiss/Krista Lenz
The only living member of the Reiss royal bloodline, Historia’s childhood was defined by isolation and self-loathing stemming from being unwanted and openly detested by her family. After her mother was killed, Historia changed her name and enlisted in the military as Krista Lenz, a road that was intended to lead to her death.
Through her relationship with Ymir, Historia found confidence in herself and eventually set out on a path to reclaim her name. Since then, she has experienced things that nobody should ever go through, and despite all that, Historia has continued to move forward.
Annie Leonhart
The main antagonist of Attack on Titan’s first season, Annie slipped into the Survey Corps alongside Reiner and Bertolt. A selling point of the series is its unpredictability. While this is clear from the start, early moments such as Eren’s “death” and Annie’s exposure as the Female Titan helped reinforce this dimension.
Trained to be a soldier from a young age, Annie was chosen as one of Marley’s Warriors and sent to retrieve the Founding Titan from behind the Walls. Although she disappears from the series for long spells, Annie’s presence as Attack on Titan’s first major antagonist cemented her as one of the franchise’s most iconic characters. Subsequent seasons would also recontextualize Annie’s actions.
Jean Kirstein
Unlike some other people, Jean enlists in the military to try and join the Military Police Brigade, a position that would provide some degree of protection and comfort. Serving an antagonist role in the early chapters, Jean often clashes with Eren, primarily due to the fact that both characters have a tendency to let their emotions run wild.
Despite initially coming across as somewhat of a throwaway figure, Jean blossoms into a well-rounded character as the narrative progresses. He even assumes a leadership position, something that would have seemed impossible during season one. The anime’s characters tend to be polarizing, in the sense that the writing for them is often regarded as one of Attack on Titan’s weaker points. However, Jean is somewhat of an exception as the series expertly leads him on a straightforward and realistic arc that never feels contrived.
Connie Springer
Another character introduced as part of the 104th Training Corps, Connie is immediately likable. Good-natured and approachable, Connie doesn’t have any lofty or heroic ambitions when he joins the military and just wishes to carve a road to the Military Police Brigade.
Like Jean, Connie becomes inspired by the likes of Eren to take this opportunity more seriously, something that is cemented once he has a direct confrontation with the Titans. In the anime’s later seasons, Connie gradually transforms into an angrier figure, leaving behind the positivity that once defined him. Even if he is not as important or ever-present as Eren or Mikasa, Connie witnesses more than his share of horrors, all of which play a part in hardening the soldier.
Ymir
Ymir has led a complicated and tragic life. The cynical and bitter figure that debuts as part of the 104th Training Corps is not simply acting out – Ymir has been to hell and back. Born in Marley, Ymir was nameless and homeless until she got picked up by a cult and turned into a prop for worship.
Eventually, Ymir was betrayed, tortured, and left to die. However, she turned into a Titan and spent the next 60 years roaming the wasteland. In 845, she reverted to human and, five years later, found herself in the military. Unsurprisingly due to her history, Ymir is not the most approachable person, and she keeps her 104th comrades at an arm’s length. That said, her friendship with Krista is genuinely endearing and helps add dimensions to both characters.
Sasha Blouse
Attack on Titan’s resident eater, Sasha is always looking for her next meal, a trait stemming from her background as a hunter from a small village. Due to her sequestered upbringing, Sasha doesn’t have much experience with people from the Walls; consequently, it takes her a while to adjust to life in the military.
In a universe filled with haunted, dark, and broken characters, Sasha’s warmth and primal simplicity allow her to stand out positively. AoT’s world could use more people like Sasha, even if she does take a while to get past some prejudices. The great thing about characters like Sasha, Jean, and Connie is that they are just ordinary people who are trying to make the best of a terrible situation. They are not destined for greatness or have lofty ambitions, and they grow from their experiences rather than in pursuit of a future.
Marco Bott
One of the unsung heroes of Attack on Titan’s early seasons, Marco adds a touch of normalcy to the series. An empathetic character who generally tries to see the best in others, Marco plays a subtle but important part in uniting the 104th Training Corps. In fact, Marco is arguably the main reason Jean matures so much in the span of roughly a year.
Marco’s time on the show is relatively short, but he makes the most of it, leaving a long-lasting impression that influences plenty of other characters. In some ways, Marco is too good and trusting to survive long in a world as harsh as Attack on Titan’s, and these qualities directly lead to his demise.
Floch Forster
While essentially a minor character, Floch goes through quite an arc in Attack on Titan. Part of the Scout Regiment, Floch has seen his share of tragedies, particularly the Battle of Shiganshina District. Floch was a significant supporter of Erwin and pushed heavily for the commander to be saved over Armin when only one of them could receive the Titan injection. Throughout the character’s run, he has always sought someone to follow, a person that he can attach his hope for the future. Originally, Floch found this leader in Erwin; later on, he switched allegiances to Eren.
In Attack on Titan: The Final Season, Floch goes from a background player to a standout antagonist, one who fully supports Eren’s desire to eradicate everyone outside of Paradis Island. While there are far more intimidating characters in the anime, Floch is strangely unsettling as he uses logic to justify heinous acts, claiming them to be for the greater good. Basically, he is a very human villain.
Louise
The Jeagerists play a significant role in Attack on Titan season 4 as they represent the internal strife tearing Paradis Island apart. Opting to follow Eren alongside Floch, Louise is one of the group’s younger members as she was just a child when the Battle of Trost District took place in 850. During this moment, she was saved from a Titan by Mikasa, a feat that greatly shaped Louise’s mentality as she embraced the idea that only the strong will survive.
In the grand scheme of things, Louise is a minor character in AoT, but she represents the political intrigue that defines the final stretch of the manga and anime. By season 4, the show has long since left behind its human versus monster roots, developing into something far more complex.
Daz
Another member of the Jeagerists, Daz is a perfectly ordinary person who is just utterly horrified by the state of his world. As part of the 104th Cadet Corps, Daz participated in a number of the most important and vicious battles in Attack on Titan, experiences that did little to ease the character’s anxiety or fear.
Daz is nothing more than a minor character, but he illustrates the story’s nuanced development in the fourth season. Although the Jeagerists are essentially antagonists, the members themselves are not villains. Daz is just scared and sees Eren as a potential savior. Honestly, this character is quite relatable.
Samuel Linke-Jackson
Samuel and Daz are two faces that are likely to haunt Connie for the rest of his days. Similar to Daz and Louis, Samuel agreed with Eren’s aggressive attack against Marley, finding great solace in the show of strength. Naturally, Samuel did not accept Eren’s incarceration and joined the rebel forces as part of the Jaegerists.
Samuel is a rather nondescript character. He does not have a unique look, a loud personality, nor is he especially talented; basically, he is ordinary. He probably feels somewhat expendable, fearing a future where he is just a nameless and voiceless person killed in a war. With the Jeagerists, Samuel found a way to be heard, at least for a short while.
Petra Ral
A prominent member of Levi’s Special Operations Squad, Petra Ral served a crucial role in fostering a bond between the group and Eren. Although a minor character, Petra’s endearing and warm personality helps balance out Levi’s directness; without her, the Special Operations Squad would not function as smoothly as it does.
Attack on Titan has a massive cast of characters, so much so that people such as Petra tend to get lost in the shuffle. However, her contributions should not be ignored as she is one of those figures who add a touch of heart to the anime.
Dot Pyxis
A stable and reassuring presence throughout Attack on Titan, Dot Pyxis is the type of character who mainly lingers in the background but also never feels out of place when asked to assume a more prominent role. The officer served as something of a mentor to the 104th Cadet Corps during their training, and he was a crucial figure during the battle in the Trost District.
A leader on and off the battlefield, Dot’s ability to remain calm even when surrounded by tragedy and destruction is his greatest asset. Driven by logic, Dot can analyze a situation holistically and come up with a solution that is realistic, all the while still taking into account the human element.
Kitz Woermann
Kitz Woermann is a puzzling character as his behavior can be unpredictable. Despite rising to the rank of captain in the Garrison Regiment, Kitz has shown a capacity to react rashly in the face of unexpected or dangerous situations. The peak example of this type of response is when Kitz learns that the Attack Titan is actually Eren Jaeger, causing the captain to threaten to put an end to the cadet. Now, to be fair, this revelation would have caught anyone off guard at this point in the story; consequently, Kitz’s fearful reaction to Eren’s predicament is understandable. However, the captain’s rash decision to eliminate Eren could have cost Paradis Island one of its greatest weapons.
Kitz has largely disappeared since the anime’s first season, only showing up sporadically as a background character. That said, he seems to have steadied his nerves since his encounter with Eren.
Rico Brzenska
A member of the 1st Division Elite Forces, Rico Brzenska plays a key role during the Battle of Trost District arc in Attack on Titan’s opening season. Since then, she has done very little of note, although she is still alive come to the end of season 4 part 2. Rico is one of the first soldiers to learn that Eren is the Attack Titan, and she agrees with Kitz’s decision to kill the teenager along with Mikasa and Armin.
This action paints Rico as a person who cares little about life, but that is not really the case. In truth, Rico is entirely driven by a desire to save as many folks as possible and to ensure no death is pointless. She is willing to carry the burden of executing three cadets if it means protecting hundreds of people. Once Dot Pyxis confirms that Eren should be spared, it does not take long for Rico to start supporting the cadet.
Kenny Ackerman
Attack on Titan’s season 3 shifts things around by revolving the main conflict around a group of humans rather than Titans. Levi’s uncle and a killer, Kenny seeks to take the Founding Titan’s power for himself.
Caring little for human life, Kenny’s actions have a ruthlessness to them that, in some ways, makes him more terrifying than Titans. To some extent, Kenny enjoys killing, making an active choice to snuff out someone’s life. He is the closest thing to a serial killer in AoT, and Kenny’s connection to Levi injects emotional weight into his story. Narratively, Kenny’s arc paves the way to plenty of revelations regarding the true history behind the Walls and Titans.
Yelena
Yelena is a complicated figure, and also one that serves an important purpose in not only the story but Paradis Island’s trajectory. Born in Marley, Yelena feels no love for her country, and she is inspired by Zeke Yeager to form the Anti-Marleyan Volunteers.
Along with people like Onyankopon, Yelena defects and joins the Eldians out of a commitment to Zeke. Although Yelena’s backstory proves to be a bit of a sham, she is still important as she gives the Eldians, particularly Armin, the belief that they can prove to the rest of the world that they are not devils. This group serves as an example that peace could theoretically be possible.
Gabi Braun
Presented as a mirror of Eren, Gabi hails from Marley, where all her life she has thought that anyone from Paradis Island is a devil. Fearless and unflinching in her hatred for the Eldains from the Walls, Gabi’s blunt nature and hard-headedness make her a difficult character to like, although this does change somewhat in the War for Paradis arc.
Rash, stupidly brave, and incredibly gifted, Gabi throws a fascinating wrench into Attack on Titan’s final arcs. As she gets first-hand experience of life on Paradis Island that challenges her ingrained beliefs about the people who live there, Gabi slowly changes her attitude as she realizes that things are not quite as black and white as she once thought.
Porco Galliard
Like Gabi, Porco is introduced at the beginning of Attack on Titan’s season 4. Picked as one of Marley’s Warriors, Porco took over the role of the Jaw Titan following Ymir’s death.
Overconfident in his own abilities, Porco has a habit of butting heads with his fellow Warriors, and he has an especially turbulent relationship with Reiner. Porco doesn’t get too much screen time in the anime, but the character’s aggressive personality and strength in battle still manage to shine through.
Pieck Finger
Another member of Marley’s Warriors, Pieck is the most immediately likable member of the group, courtesy of her easy-going and unassuming nature. As the Cart Titan, Pieck serves a supportive role in her unit, and this is reflected by the character’s strategic approach to combat scenarios.
Kind as she can be outside of battle scenarios, Pieck is not to be underestimated when the going gets tough. She is more than willing to do what is necessary to ensure the safety of her comrades and people.
Colt Grice
One of Marley’s Warrior candidates, Colt is expected to become the Beast Titan once Zeke’s time in the role is completed, at least if everything goes to plan. A soldier who is capable on the battlefield and off it, Colt’s brilliant tactical mind has made him indispensable to Marley’s cause, despite his status as an Eldian working against him.
Colt only appears sporadically in part 1 of Attack on Titan’s season 4, but his role is expanded in part 2.
Falco Grice
Falco tends to be overshadowed by the likes of Gabi and his brother, Colt. Not one of Marley’s Warriors and lacking much in the way of physical prowess, Falco is not built to be a fighter, although that doesn’t discourage the child from sticking his neck out if the moment calls for it.
Falco is brave but also slightly naive, as can be seen through his interactions with Kruger. Narratively, Falco serves an important role as he is the most ordinary character introduced in season 4’s perspective change.
Ymir Fritz
Arguably the most important figure in Attack on Titan’s history, Ymir Fritz set the stage for most of the events of the anime, both directly and indirectly. That said, very little is known about Ymir as a person or what she accomplished.
More than a thousand years prior to the anime, Ymir gained the power of the Titans. This ability was abused by Eldia’s king, bringing ruin to Marley. Ymir passed away 13 years after receiving her powers, which were then passed down from generation to generation as the Nine Titans. Ymir is an incredibly tragic character, someone who was turned into a weapon and forced to accept a legacy drenched in blood, sorrow, and death.
