AAA Wunder is not a human character but rather a highly advanced flying battleship introduced in the Rebuild of Evangelion film series, specifically in 'Evangelion: 3.0 You Can (Not) Redo.' Operated by the organization Wille, the AAA Wunder serves as the primary headquarters and transport vehicle for the main cast, including Misato Katsuragi. It plays a crucial role in humanity's resistance against NERV and the Angels, symbolizing hope and technological prowess in the fight for survival.
