Reiner Braun is the Vice Captain of the Warrior Unit and the main protagonist of Attack on Titan from the Marleyan perspective. He is the illegitimate son of an Eldian and a Marleyan and grew up in Liberio's internment zone. Eventually, he was selected as a child to become one of Marley's Warriors. At the age of ten, he inherited the power of the Armored Titan. While still loyal to his true cause as a Warrior of Marley, he was unable to cope with the guilt he felt towards his actions and thus began to suppress his true memories in an effort to escape. Having to kill Marco seems to have been the final straw for him, causing him to snap and developing psychological issues. During these times, he would forget his actual identity and truly believes himself to be an Eldian soldier. Even after blowing his and Bertolt's cover, he initially still continued to shift between his two personas. However, after Bertolt bluntly told him that he was not a "soldier" but a "warrior", Reiner was, though with some difficulty, able to set his priorities straight.
