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 is set to launch into its final season at the beginning of 2022.

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 characters' ages, heights, and birthdays.

Updated on September 2, 2021 by Mark Sammut: In January 2022, Attack on Titan will start its final anime season, bringing together a saga spanning approximately a decade. Throughout this time, the series has managed to engrain plenty of characters into the public consciousness, especially the likes of Levi and Mikasa. In celebration of the anime's past and future, this article has been expanded to cover a wider selection of Attack on Titan's most popular characters.

Attack On Titan Statistics Chart

The Survey Corps in Attack on Titan
Attack on Titan's roster of (important) characters is quite extensive, so much so that this list has ballooned to 18 entries. In order to make the information as readily accessible as possible, the following table has been constructed to provide a breakdown of each character's age, birthday, and height.

Disclaimer: Unless stated otherwise, the statistics are based on the character's status in the Year 850 since that is when most of Attack on Titan's story takes place. If someone debuted after that point, their first appearance will be used. Also, as Attack on Titan hasn't revealed the exact age of every character, estimates are given for those entries.

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.

18 Eren Yeager

attack on titan 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.

attack on mikasa
Eren's right-hand partner, Mikasa Ackerman is 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 kidnapped 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 the protagonist's brash and direct nature.

attack on titan anime armin
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 a voice of reason.

Arguably the anime's most beloved character, Levi is the strongest fighter 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 of 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.

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.

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.

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.

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.

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, reflecting their more authoritative role in Attack on Titan.

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.

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 being exposed 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.

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 Attack on Titan proceeds. He even assumes a leadership position.

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.

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 back to human and, five years later, found herself in the military.

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 in a positive way.

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.

Presented as a mirror of Eren, Gabi hails from Marley, where all her life she has been 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.

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 far more terrifying than Titans; to some extent, Kenny enjoys killing. Narratively, Kenny's arc paves the way to plenty of revelations regarding the true history behind the Walls and Titans.
