Eren Yeager

Eren Yeager is a member of the Survey Corps and the main protagonist of Attack on Titan. He lived in the Shiganshina District with his parents and adopted sister Mikasa Ackerman until the fall of Wall Maria. During the incident, Eren impotently witnessed his mother being eaten by a Titan. This event aroused in Eren an intense hatred towards the Titans, and he swore to wipe all of them off the face of the Earth.

In the AWA fics, Eren is a student at the AWA Academy and is part of Class 1.

Appearance
Eren is a young man of average height and muscular build. His facial features strongly resemble his mother's; he has a fairly long, rounded face and sizable, expressive gray eyes. His hair is short and brown, and his bangs fall in a natural middle-parted curtain-type style. His complexion appears to be somewhat tan. After his training and during his time as a soldier, he became very physically fit and muscular, although this is often unseen due to his relatively baggy clothing. During the Four-year timeskip, Eren grew long hair running down to his neck.

He is first seen wearing typical townsfolk attire that consists of brown trousers, a green shirt with string tassels at the collar, a reddish-brown coat, and simple brown shoes. A few years before the fall of Wall Maria, he also wore a black scarf, which he gave to Mikasa the day they met. As a teenager, he was often seen in the typical Survey Corps uniform while training. His casual attire consisted of a long beige shirt identical to the one he wore in his first appearance, a maroon sash around his waist, white trousers, and brown knee-high boots. He always kept the key given to him by his fatherdangling around his neck on a string.

By the time he infiltrates Marley in the year 854, he is visibly taller, and his hair is shown to have grown to shoulder length. He currently has a slight mustache and goatee, and he wears bandages that cover his forehead and left eye. To maintain his cover, he wears the Eldian armband around his left arm; he had initially worn it around his right before being corrected by Falco.

Personality
Eren is best described as hardheaded, strong-willed, passionate and impulsive, which are attributes of both his strong determination to protect mankind and, eventually, his equally strong determination to escape the Walls. Even as a young child, he was so intent on joining the Survey Corpsthat he argued with and shouted at his mother, referring to the people in the village as "silly" and comparing them to complacent livestock.

Eren cares deeply for his friends and family, risking harm and even death in order to protect them. As a child, he took on larger boys who bullied Armin and, more tragically, he attempted to lift the rubble that crushed his mother during the Titans' assault in Shiganshina. Eren is also capable of displaying violent behavior in defense of people he does not even know. This was highlighted when he attempted to rescue Mikasa by brutally slaughtering two of the human traffickers who had captured her.

After Armin showed Eren a book depicting the wonders of the outside world, he grew to share his friend's curiosity of the world beyond the Walls and decided to see it for himself. This led Eren to develop a scornful attitude towards anyone who was content to live and die within the Walls' confines without ever setting foot outside. As a result of this, he greatly admired the soldiers of the Survey Corps, regarding them as "heroes" and wishing to join their ranks as soon as he became eligible for enrollment. He was quick to take offense when anyone spoke badly of the Corps, and his determination to join them caused friction between himself, his mother, and to a lesser extent, Mikasa.

Eren has a marked lack of self-restraint that often leads him into trouble, causing his friends and family to worry about him. His limited self-control is evident in his temper, which often caused him to act recklessly in anger, or say things he himself knew he should not have. This is exacerbated by his tendency to view the world in terms of black and white, where individuals who deny others their freedom are worthless scum unfit to be left alive. Though he has great compassion, Eren has little in the way of empathy and is prone to taking things at face value, evaluating situations or ideas solely by his own arbitrary perspective and rarely ever thinking deeper about them unless someone else points things out for him.

Abilities
Originally, Eren's only noteworthy trait was his natural physical strength, which stemmed from having to defend his friend Armin from bullies who were bigger and stronger. As he grew and joined the 104th squad, he trained extensively in hand-to-hand combat. After additional training with Reiner and Annie, Eren's prowess and skill set diversified, including the use of punches, throws, grappling and submission locks. He had the best scores for hand-to-hand combat of the entire 104th graduate squad. While hand-to-hand fighting would appear useless due to the massive physical differences between humans and Titans, these skills gave Eren a powerful edge when fighting other Titans in his own Titan form.

Though having little talent, through intense training and effort he managed to gain a considerable amount of skill with the equipment. Even so, Eren was not completely lacking in natural aptitude. While using the damaged equipment, he had managed to stay upright for a short amount of time, which the instructor, Keith Shadis, said was an incredible feat, and balanced with ease when using proper gear. The fact he graduated as the 5th best of the 104th graduate squad, even before Jean Kirstein, who was top of the class in mobility with the gear, implied that he had considerable combat skill with the maneuvering equipment.

Though Eren is not shown using the equipment much, he was able to hold his own against the Colossus Titan until the Titan disappeared, almost reaching the nape twice. He was even capable of killing a Titan on his own not too long after joining the Survey Corps. His most significant use of maneuvering equipment was shown during the Battle of Shiganshina, where he was able to use it to cut Bertolt Hoover out of the Colossus Titan's nape while he was distracted by his hardened Titan form, despite being exhausted.

After the fall of Wall Maria, Grisha came looking for his family in Wall Rose, and found Eren in a refugee camp. He asked about Carla's fate and when he replied that she had been eaten, Grisha took him into the woods and tearfully told him to avenge her and defend Armin and Mikasa. He gave him the key to the basement and injected a struggling Eren with a serum, which transformed him into a normal 4 meter Titan with short rugged hair and a skinny body. This Titan ate Grisha and returned to human form. Eren cried loudly over the grisly remains of his father and fell unconscious. Keith Shadis found him and because he did not see Grisha, he took Eren back to the camp and gently placed him next to a sleeping Mikasa and Armin. Years later, during the first Battle of Trost, Eren was eaten alive by a Titan, and inside the stomach-like cavity saw other fellow recruits lying dead/dying, one wanting her mother before sinking in stomach acid. This sight combined with intense feelings of desperation and his drive to exterminate all Titans awoke his ability to transform into a Titan. This Titan is known as "The Attack Titan."

In this form, Eren is a 15 meter tall Titan, with shoulder-length black hair, pointed ears, a long nose, and a gaping, skeleton-like maw lacking lips. Unlike most other Titans, his Titan form is considerably more muscular and defined; making him much stronger than even similar-sized Titans while his intelligence and military training, allow him to out-maneuver and dispatch entire groups of Titans with ease. A transformation takes a heavy toll on Eren’s body and requires large amounts of stamina. As a result, he has displayed several symptoms when he over-exerts himself such as a nosebleed, pale skin, and labored breathing. In some cases, Eren is rendered unconscious for a short period of time after a Titan transformation.
