In the original Doraemon: Nobita and the Steel Troops movie, Judo/Pippo is shaped like a bowling ball and later getting reworked by Doraemon becoming their allies. In the Doraemon: Nobita and the Steel Troops' remake, Pippo is chick-like Mechatopian robot serving as Judo's brain and Riruru's partner. He was originally shaped like a bowling ball until Doraemon turn him into his current shape by "Talking Box". Like all Mechatopian, he views human beings as inferior compared to machines, although this view changes as the story progresses.
