The Psychomotion is an Italian independant film that was picked up by Walt Disney for a television series in Disney XD. The cartoon's art style parodies Japanese animation with some elements of the early-late 1980s and the early 1990s culture, especially the soundtrack and gadgets. Mostly the film is based on the "ninja" genre.
Two siblings who are the sons of a great warrior that was trapped in a mystical orb are about to free him but an evil villain is about to stop them.
