Annie Leonhart

The Female Titan is one of the villains of Attack on Titan and revealed to be Annie Leonhart. A 14-meter tall Titan with a previously unheard of feminine body structure, encountered during the expedition to Wall Maria. She possesses obvious intelligence, extensive knowledge of hand-to-hand combat, and the ability to selectively regenerate or harden parts of her body during battle. Leading numerous other Deviant Titans, she attacks the expedition forces in search of Eren and attempts to kidnap him. She slaughters the forces sent to fight her, with only Levi, Mikasa, and Armin surviving direct contact with her.
