 The characters of "Chrono Trigger" were designed by Akira Toriyama based on sketches from the story planner Masato Kato.The development team wanted a diverse cast to reflect the various eras visited by the player; while working on the in-battle actions of the game, they decided to include a playable character that was neither human nor robot.Kato drew sketches for a cast of eight playable characters, comprising a male protagonist, the daughter of a fairy king, a tin robot, a monster man, an inventor girl, a demon king, a primitive girl, and an old sage.
