Zeke Yeager (ジーク・イェーガー) is the former Captain of Marley's Warrior Unit, assigned to take the Founding Titan from the Eldians of Paradis Island. He is the current inheritor of the Beast Titan, and considered by Reiner Braun to be the strongest Warrior, contrasting Levi Ackerman's title of "humanity's strongest soldier."
Zeke is the son of Grisha Yeager and Dina Fritz, the older half-brother of Eren Yeager, and a member of the royal family from his mother's side.
