Grisha Yeager

The Shiganshina doctor, father of Eren and Zeke: born in Liberio's internment zone, a revolutionary of the Eldian Restorationists, he brings the Attack Titan into the Walls and steals the Founder from the Reiss family.

As a boy he leaves the ghetto to see an airship: his little sister Faye, who follows him, is killed by Marleyan officers. As an adult he joins the Eldian Restorationists, marries Dina Fritz, a descendant of the royal family, and raises Zeke as a tool of the revolution. Zeke reports them: Dina becomes a pure Titan on the borderline, Grisha is saved by Eren Kruger, the Owl, who passes him the Attack Titan. Inside the Walls he starts a new life with Carla. On the night Maria falls he goes to the Reiss chapel, devours Frieda and then lets Eren devour him — but the memories reveal that it was Eren, from the future, who drove him on.
