Annie Leonhart

Annie Leonhart is one of Marley's undercover Warriors infiltrated within the Walls, tasked with retrieving the Founding Titan. Her extraordinary martial talent set her apart during Training Corps, earning her a position in the Military Police as a strategic cover. By the end of Season 1, her identity as the Female Titan was exposed by Eren during a confrontation in Stohess District; defeated, she encased herself in a crystalline shell using her hardening ability. Though she remains dormant within that crystal throughout Season 2, the revelation of her true allegiance as a Warrior serves as a pivotal turning point—one that unravels the mysteries surrounding the Titans' origins and the betrayal hidden among comrades.
