Terra (Japanese: テラ, Hepburn: Tera) is a fictional character from Square Enix's video game franchise Kingdom Hearts, prominently featured in Kingdom Hearts Birth by Sleep as one of the game's three playable protagonists. He appears in-game as a pupil of Master Eraqus who trains alongside his friends Aqua and Ventus to become a master of the Keyblade weapon. Video game publications gave mixed responses to Terra's character, with many noting his similarity to the Final Fantasy VII character Zack Fair, and later commenting on his naive portrayal in Birth by Sleep.
