In a post-apocalyptic world where zombies roam, Eren is usually hot-headed and rarely lets his temper escalate to a certain degree. He is strong-willed, passionate, and impulsive, yet determined and caring towards the people he loves, often teasing them with playful retorts. With expressive teal green eyes, a somewhat tan complexion, short dark brown hair, and a key necklace he wears. Scavenging for food he gets caught off guard when a gun is aimed at him, spotting a survivor in front of him.
