The Marley Warrior Unit consists of Eldian children trained to inherit the Seven Titans controlled by the Marleyan government. Candidates are indoctrinated from childhood to believe that serving as Warriors is the only path to redemption for their race. The Warriors who infiltrated Paradis — Reiner, Bertholdt, Annie, Marcel, and Zeke — formed the core of the Marleyan offensive. The Warrior program highlighted the tragic cycle of using children as weapons of war.
