Eren Yeager

Eren has fair skin, gray eyes, and black hair. He is a thin, moderately muscular teenager with a tall, 170 cm (5'7") height. He has thick eyebrows, short, neck-length hair with bangs that slightly expose his forehead, and is usually seen frowning.

With his Titan form, Eren's appearance changes drastically, however, there are some qualities that make him recognizable. Along with a massive increase in height (reaching a 15m Titan), his hair grows to the length of his chin and his eyes become long and thin compared to normal eyes, which are round and wide, although the blue-green color of the irises is retained. His tongue, nose and ears become more prominent and pointed and his teeth become dagger-like, deformed, multiply and form two rows. Compared to most other regular Titans, Eren's Titan form has a good physical appearance, having a large muscle mass instead of a belly, Eren has skin on his entire body compared to other Titan shifters who have a muscular appearance.

Eren has always been a determined person, with strong ideals and a strong sense of justice since he was a child. Since his childhood, he hated living locked up behind walls and instead longed to join the Survey Corps to explore the outside world.[11] This dream came about thanks to his childhood best friend, Armin, who showed him a book about natural phenomena in the outside world. Eren greatly admired the Survey Corps recruits and considered them "heroes" for their great deeds, even if they were not successful in their expeditions.

Eren's ideas led him to argue with his mother and be disapproved of by Mikasa, but his father supported his dream. Eren was also very curious and had hopes of one day uncovering the mysteries of his father's basement. Due to his passion and impulsiveness, Eren was able to do whatever he wanted regardless of what others thought of him. His strong determination led him to stand up for those he loved, such as when he protected Mikasa from thieves and his best friend Armin from the local town bullies.

At times, Eren appeared to be a bit rough and not as gentle as Armin, making him seem somewhat uncaring. However, overall, Eren was a happy child who greatly appreciated his everyday life with his nuclear family and his friend Armin. After witnessing his mother's terrible death, Eren was driven by a desire for revenge and set out to kill all the Titans in the world, whom he blamed for his tragedy and unhappiness. Eren lamented that the last conversation he had with his mother was a fight with her.

In his early teens, between the ages of 12 and 14, Eren joined the militia with great effort to fulfill his goal. He maintained good camaraderie with the other recruits and stood out for his strong dedication to the expeditions, although he never became a leader like Reiner Braun, another recruit with whom he got along well. The fact that he had suffered a Titan invasion

The destruction of his home brought him closer to Reiner and Bertolt Hoover. Despite being stubborn, Eren was able to listen to ideologies different from his own, as happened when he met Annie Leonhart. This made him reflect on the true values ​​to consider in training.

Eren was also willing to work with others, often asking other recruits for help or advice. For a time, he received training in combat techniques from Annie. He valued the lives of his comrades greatly and was willing to avenge their deaths, even if they were comrades he didn't know well, as was the case with Thomas Wagner. He also valued people with well-defined ideals, such as Armin's dream of exploring the outside world and Annie's sincerity about her own priorities. With the power he possessed, Eren felt a great responsibility as humanity's only hope.

Eren faced internal doubts about having to face traitorous comrades after having placed his trust in them for years. Eventually, he did his best to deal with it and benefit humanity. One of Eren's most notable traits as a recruit was his determined mindset; he wouldn't let the Titans deter him from his dream. Some recruits thought Eren was "strange" and even "suicidal" for his desire to confront the Titans, but others were drawn to his demeanor, including Jean Kirstein and Annie Leonhart.
