Ratchet was the chief medic for the Autobots in the 1984 Transformers cartoon. He could be grumpy at times but would always take his duties as a doctor and mechanic very seriously. He was voiced by Don Messick.
Ratchet had a very minor, non-speaking role in Transformers: The Movie, being a member of the crew of the shuttle bound for Earth early in the film. He was gunned down by the Decepticons when they hijacked their shuttle.
