Annie Leonhart graduated from the 104th Cadet Corps, securing fourth place through exceptional swordsmanship and unarmed prowess. Born to an Eldian mother within an internment zone, her identification as a Subject of Ymir led to adoption by Leonhart, who subjected her to brutal Warrior training for Marley. This regimen culminated when she crippled her father in a violent outburst, cementing her emotional detachment and indifference toward others’ fates. Chosen as the Female Titan, she infiltrated Paradis Island alongside Reiner Braun, Bertholdt Hoover, and Marcel Galliard. Posing as a refugee, she adopted a solitary demeanor during military training to evade emotional bonds, aiming to join the Military Police for a tranquil life and eventual reunion with her father. In the Battle of Trost, Annie’s Female Titan slaughtered Survey Corps soldiers and targeted Eren Jaeger, employing crystalline armor and strategic precision. Though ruthless, she expressed fleeting remorse—apologizing to a fallen comrade and recoiling from Marco Bott’s death, which Reiner coerced her into enabling. Armin Arlert exposed her identity, triggering a clash in Stohess District. To evade capture, she encased herself in a crystalline shell, remaining comatose for four years. During this stasis, she grappled with her past, later confessing her crimes to allies like Hitch Dreyse. Post-escape, she allied with former adversaries to halt Eren Yeager’s genocide, displaying newfound cooperation. Though acknowledging Armin’s kindness during her imprisonment, she still viewed herself as irredeemable. Her father’s desperate wish for her survival persistently guided her choices. Sarcastic and self-aware, Annie approached conflicts with pragmatism, often masking vulnerability with violence—evidenced by clashes with Reiner. Despite her icy exterior, she respected duty-driven figures like Marlowe Freudenberg and once wept after failing to secure Eren. The *Lost Girls* OVA unveiled her torment over Marco’s demise and internal strife regarding her mission, juxtaposing her detachment with profound regret. Physically, Annie’s short stature, blonde hair, and muscular frame contrasted her Titan form’s exposed sinew and enhanced agility. This form could summon Titans via scream and generate crystalline defenses. A concealed blade within her ring enabled transformations through self-inflicted wounds.
