Armin Arlert (アルミン・アルレルト Arumin Arureruto?) is a childhood friend of Eren Yeager's and the deuteragonist in the series. Although physically more frail than most, if not all of the current recruits, he has proven his skills as a field tactician and strategist with his high intelligence.


Armin is rather short for his age with a petite build; this lead to his constant bullying as a child. Armin has a round face, framed by his blonde hair and he has round blue-eyes and a pudgy nose. Unlike Eren, he typically wears a calm look with his eyebrows cast downward that changes from determined, when being strategic, or wide-eyed when shocked or surprised. 

During his childhood, he wore a long-sleeved suit-like jacket with a collared shirt, long dress-pants and dress shoes. As a solider, Armin wears the traditional Survey Corps uniform. Underneath his short brown jacket, he wears a white and collared button up shirt, similar to the one he'd worn as an adolescent. Armin also accompanies his attire with a large green cape when assigned missions on the exterior of the Wall.

Armin ready to save the situation

Armin was very timid as a child, and coupled with the fact that he was physically frail, often ended up an easy target for bullies. He was so timid that he would refuse to fight back despite being taunted to do so, always needing Eren Yeager and Mikasa Ackerman to fend for him. As such, he grew up having very low opinion of himself, thinking that he was useless. He enlisted only because his two best friends, Eren and Mikasa, were enlisting. Despite being timid, he has a variety of traits and talents that contrasts to his timid self, which began showing as he grew older and learnt to appreciate his own talents and develop a higher opinion of himself. He has a big dream of wanting to venture outside the walls to see the world - a dream that he shares with Eren. He is also a loyal person who is willing to put himself in harm's way to defend a friend, shown when he was, along with Mikasa, willing to defend Eren against hostile fellow soldiers despite the very high risk of being killed. During training, despite always on the verge of failure due to his physical frailty, he was shown to be very persistent despite the odds, refusing to give up and did his best to catch up with his friends. He was also shown during training to have a sense of dignity when Reiner offered to carry his gear for him during a drill and he refused the offer outright due to the fact that doing so would mean that he was weak and uncapable. He is the brains of the team and he impressed Dot Pixis, the high ranking officer in charge of the cities defense, by his brilliant plan to attract the Titans during the battle of Trost.


Before Year 845

Armin originally lived in Shiganshina with his parents and grandfather. He was a close friend to Eren and used to discuss with him about the outside world with its salty oceans, deserts and other surreal places. He inspired him to dream about being free and explore the world beyond the Walls. He used to get into trouble with local bullies for talking about the outside world and was regarded as a heretic.

In year 845, Armin is first introduced being confronted by local school bullies until Eren and Mikasa come to his rescue. The trio would then loiter around as Eren continues to muse about his desire to join the Survey Corps. Later in the afternoon, the Colossal Titan would appear and breach the Shiganshina district of Wall Maria, which causes Eren and Mikasa to head in the direction of their house. Though Armin attempts to call out to them, he holds himself back out of fear. Unbeknownst to Eren and Mikasa, he asks Hannes to fetch the two as they were going too close towards the Titans' direction. He and his grandfather sit aboard a ship, waiting for Eren and Mikasa. A year later, Armin's grandfather left with other refugees on a campaign to retake Wall Maria. However, he died on the mission and Armin was left alone with Mikasa and Eren.

104th Trainees Squad arc

Armin decides to join military training along with Mikasa and Eren, because after his parents and grandfather got killed, he couldn't sit around doing nothing. He was able to pass the basic aptitude test after some effort and tries to help Eren with it. Armin was considered weak in physical strength and graduated below the top ten. However, he was top of the class when it came to theoretical courses. Although his plans have saved Eren and Mikasa several times, he doesn't realize it and despises himself for being reliant on them.

Battle of Trost District arc

Armin fears humanity's fate when he hears of the attack on Trost. He trembles in fear and was having problems in fixing his gear, when Eren tells him that not all was lost. Armin joins Eren's squad to guard the middle of Trost and departs with him to their prescribed location. On the way, Titans attack and eat up everyone in his squad except him. Armin supposedly blamed himself for allowing Eren to sacrifice himself to the bearded Titan. Mikasa tells Armin that his strategies have always saved their lives and he should have more faith in himself. 

In Trost's military headquarters, a number of Titans were attacking them and had took control of the supply depot. Armin devised a plan, wherein the soldiers would lower themselves via an elevator and lure the seven Titans towards them. As soon as they get close enough, everyone would shoot their eyes with firearms, momentarily blinding them and seven skilled soldiers, who would be hiding beforehand, would attack and kill those Titans from behind. The plan succeeded and everyone was able to refill their gas tanks to return alive.

After recovering Eren, he was detained by a group of soldiers and was going to be executed. Armin and Mikasa defend him, as he wakes up and is surprised. Eren plans to escape over the walls unless Armin was able to convince the soldiers regarding Eren's value to humanity. Eren tells him that his quick thinking had saved him and Mikasa before, as he was the one who went to Hannes when Shinganshina was being attacked. Armin, more confident than ever, walks over and tries convincing the soldiers about Eren's strategic and tactical importance in turning the tide of the battle in Trost. As a soldier, he passionately decides to die for this cause and makes a grand salute. Pixis notices his determination and passion and prevents their execution.

Now with a boost in self-confidence, he tells the senior strategists about a plan to retake Trost. He tells them that Eren could carry the boulder over to the hole while other soldiers could lure the Titans towards the walls. They proceed with the plan. Later, when Eren lost control and was knocked out, Armin goes running towards Eren and lands on his back. He remembers the position from where Eren had risen earlier, so stabs him a little askew so that it wouldn't be fatal, but would wake him up. He reminds Eren of his dream to go outside and his personal vendetta against the Titans. Eren, successfully motivated by Armin's effort, carries the boulder and plugs the breach.

After the news had spread that two Titans, Sonny and Bean, were slain, Armin along with other trainees from the 104th Trainee Squad are called in for inspection. Armin, Annie and Connie discuss which branch of the military they would join, in which Armin declares his decision to join. Unbeknownst to Annie, Armin notices that she is possession of Marco's Three Dimensional Maneuver Gear. He realizes that Annie might have been the one who killed the two Titans but decided not to believe his train of thoughts.

After joining the Survey Corps with Eren, Mikasa and the other graduates (excluding Annie Leonhart), they went outside Wall Rose for the Survey Corps's 57th expedition, when they were confronted by the sudden appearance of the Female Titan, seemingly knowledgeable about military formation. She attacked Armin while he was wearing his hood, under the impression that he was Eren. However, once it was removed, she realized she had the wrong subject and left him aside. Armin noticed a few things regarding the female Titan: she avoided killing Jean and him even though she had the chance, and it seemed as though Reiner had carved letters onto her palms, after which she directly charged towards the rear of the middle flank. Furthermore, she reacted to Eren's nickname when Armin deceptively called on Jean to "avenge the suicidal bastard." Adding the knowledge that Annie had used Marco's gear during the checkup, Armin realized Annie was, indeed, the Female Titan.

Armin asks Annie for her help in hiding Eren because she was in the military police and they needed her to let them pass through Wall Shina without suspicion. Annie accepts and Armin explained that he wanted to take advantage of the geography there rather than use the 3DMG to bust through. As she was leading them to a hiding place, Annie refused to go inside to help them escape and asked him why he was looking at her with suspicion. Armin then took the time to ask her the reason she was in possession of Marco Bott's 3DMG. He recognized it not too long ago because he and Marco would often do routine check-ups to make sure they were in pristine shape. Annie confessed that she found it after Marco died and that she used her own 3DMG to kill the two captured Titans. She then asked him if he had already come to all those conclusions, why hadn't he taken action earlier. Armin reasoned that he didn't do so because he wished to believe that there was still something wrong with his train of thoughts. It was when Annie refused to kill him that things turned out the way they did.

Armin attempts to capture Annie by firing the signal from his flare gun letting the townspeople capture her. As the people tried to restrain her, she managed to injure herself with a sharp metal projection hidden in her father's ring. Noticing this, Mikasa grabs both Eren and Armin and takes them further underground as Annie in her Titan form attempts to capture them. When Armin learns his plan had failed he attempted to start plan B, trying to encourage Eren to fight Annie. Eren tried to transform into his Titan form, but he was unable to do it. It was only then Mikasa and Armin learned why, he was reluctant to fight Annie again because he still couldn't believe that Annie was indeed their enemy. And he didn't want to fight against one of his comrades. Having no other option, Armin tells Eren that he and Mikasa would go out through each of the two openings. Annie would go after one of them and Eren should utilize the opportunity to escape via the other opening. Realizing that his friends were in danger, Eren finally transforms into a Titan and fights Annie. 

After Annie's capture, Armin tells Jean Kirstein that Eren's summonings to the King were cancelled and that Annie is the Female Titan. She's been detained underground after encasing herself in a crystal to avoid interrogation. Armin couldn't understand how the walls were built in the first place because there were no stones or bricks around. He hypothesizes that the Titan's hardening capabilities were employed to build the walls. He believes it could explain how Annie was able to encase herself in a crystal. Armin's hypothesis was confirmed when the rock sample Lt. Hange had picked up from Annie's body matched the crystal properties of the Walls. He and the others learn from Lt. Hange that the only way they could repair the walls is if Eren can use his hardening abilities to help fix Wall Rose. Pastor Nick tells them about a girl in the Survey Corps knowing more about what's going on and it's up to her to decide if she'll talk. Armin then recognized Krista because she was often seen with Ymir.

Clash of the Titans arc

Once the Survey Corps had rescued the others from the South Squad, Armin learns that Krista's real name is Historia and how heavily injured Ymir was during her fight with the Titans. He immediately learns of Reiner and Bertolt's secret correspondence with Annie. Like Mikasa, Armin was very angry to learn about their betrayal after overhearing the confession about them being responsible for Wall Maria being breached.

During the battle with Bertolt and Reiner, Armin states that the Colossal has very slow movements and that they should exploit it. However, they were taken by surprise when he uses his vapors of heat to keep them off him. Realising that Bertolt is just as desperate to stay alive, Lt. Hange orders Armin and the other members of the Survey Corps to go after Reiner. Armin discovers a weak link to Reiner's line of defense when he saw his armor break. Giving Mikasa and extra set of blades, he tells her to go ofter the back of his knee caps. Soon Bertolt took everyone by surprise by falling off the wall.

With Eren and Ymir now kidnapped by Bertolt and Reiner, he focuses his attention in helping Mikasa and the others until help arrives. Armin tells her the news that she had been dreading and wrapping her lower face in the scarf, she cried. She asks him why he always has to leave them behind when trouble rises. As Armin tries to console her, Hannes arrives to give out rations to everyone in the Survey Corps. He tells them that Eren has always been like that, running into fights despite knowing the odds are against him. Hannes even mentions that although he won't admit it, he always knew Armin and Mikasa were there to help him out. Reinvigorated and determined to rescue both Eren and Ymir, he takes his stance with the Survey Corps, Wall Guards and Military Police. Armin wants Historia to stay within the walls, but she refuses and decides to join them.

Armin and the others reach the Forest of Giant Trees where Reiner and Bertolt were resting. While inside the forest on their 3D gears, they notice Ymir's Titan form. Armin suspiciously notices that she was surveying everyone and wasn't responding to anyone. His suspicions were confirmed when she captures Krista and escapes. He realizes that Ymir was definitely working against them.

A short time later, he joins the other former members of the 104th in confronting the traitors. He remains silent during the initial confrontation, and is forced to briefly retreat when Erwin Smith lures a swarm of Titans into attacking the Armored Titan. When his commander is wounded and carried off by a Titan, Armin remains focused on the mission and joins the second attempt to retrieve Eren. Using his gear to climb onto the Armored Titan's head, he desperately attempts to think of what can be "sacrificed" in order to change their situation. Remembering Bertolt 's concern when Annie joined another branch alone, Armin informs her accomplices that she has been captured. Taking his bluff a step further, he inquires whether they intend to leave her behind in the Northern District, and cruelly describes how she is being tortured. This has the intended effect, shocking Reiner and driving Bertolt into a rage. This allows Erwin, now missing an arm, to wound Bertolt and free Eren. With their mission accomplished, Armin and the others attempt to retreat as quickly as possible. However, their path is blocked when Reiner panics and begins to throw Titans to prevent their escape.

This horrifies Armin, and he wonders why Reiner would do this when it endangers Eren. At some point during the battle, a Titan lands near him and knocks Jean unconscious. With no where to run, Armin drags Jean towards a small cluster of trees and prepares to face an advancing Titan with only one sword. He looks towards where Eren and Mikasa are, seeing them in just as desperate a situation. The friends exchange teary-eyed glances, preparing for the end.

He is saved when Eren's power as the Coordinate manifests, causing the Titans to attack first the Smiling Titan and then the Armored Titan. This allows Armin to retrieve a horse, and carry a wounded Jean to safety. They retreat from the battlefield, mourning for the loss of Hannes and remembering their childhood with him.

A week later, Armin would be recruited by Levi to form a new Special Operations Squad alongside the remaining members of the 104th's top 10 trainees. During their first official operation, Armin serves as a body double for Historia, and is eventually captured by the organization that wishes to take possession of Eren and Historia.

Miskos3Added by Miskos3

Being one of the physically weakest soldiers there are, he is rarely assigned to the frontlines and rarely seen using his 3DMG for fights. His main strength however, lies within his intelligence - an innate abilities in deduction and forming strategies, be it in a war room or on the fly, as well as an eye for obscure details, making him a remarkable field tactician, a trait that only he displays among the current recruits. His strategies helped save his fellow soldiers numerous times and more remarkably, he is the key person who deduced the identities of all hostile Titan shifters among the current recruits. He wasn't able to display his remarkable intelligence earlier due to a serious lack of confidence in himself. After acknowledging that he is actually far more useful than he thought he is, his genius as a tactician began to show and thus far, even commanders are shown to take his opinions in matters relating to Titans seriously.

Armin Arlert's Statistics[2]:

Battle Skill


  • Eren Yeager - Eren is Armin's closest friend. Armin has always looked up to Eren as he was always trying to save him from local bullies. He used to discuss with Eren about the outside world and gave him dreams about exploration and freedom. Armin initially felt that he was worthless and incompetent in front of him. Eren, on the other hand, believed that his reasoning abilities had saved him and Mikasa a number of times and trusted him deeply. Eren gave him enough confidence to face a group of soldiers to convince them of his strategical value to humankind.
  • Mikasa Ackerman - Mikasa is a close friend of Armin's. Whenever Armin got into trouble with local bullies, Mikasa would come and save him. Armin looked up to Mikasa's strength and courage and felt inferior to her. Mikasa, however, believed in Armin's abilities to reason out the best solution in a dire situation and trusted him deeply. She was responsible for boosting Armin's confidence and shaping his character.
  • Jean Kirstein - While Armin was initially not that close to Jean due to the latter's rivalry with Eren, their relationship has changed considerably since joining the Survey Corps. Armin's growth as a strategist has aligned with Jean's growth as a leader, and the two often share insights or opinions with one another.
  • Annie Leonhart - The two are shown to share a mutual respect for each other, expressing admiration for each others' hidden qualities. This causes her to hesitate when attacking in her Titan form, a mistake which allows Armin to discover her true identity. He then uses emotional blackmail in order to lure her into a trap and facilitates her eventual capture.
  • Reiner Braun - Reiner is shown to have been protective of Armin, helping him during physical training exercises and carrying him to safety during dangerous operations. Armin initially defends him when he is suspected of being a spy, but quickly realizes the truth and provides evidence of Reiner's guilt.
  • Marco Bott - Armin notes that they were friends, and did maintenance of their gear together. This later allows him to recognize Marco's stolen gear when it is presented by Annie as her own.
