Ratchet (rach-it) (Ratchet/Mécano in Canada, Racsni in Hungary, Рэтчет in Russia and Doc in Italy) is the chief medic of the Autobots in the Transformers television and comic series based on the popular toy line produced by Takara and Hasbro. His vehicle mode is an ambulance. Named after Nurse Ratched by writer Bob Budiansky, who originally intended the character to be female, an idea rejected by Hasbro. Ratchet is well-remembered by fans of the original comic series, in which he played a major role.

Ratchet would transform into an ambulance (cargo van type) and was colored white with red stripes and emergency lights. Ratchet had two robot modes, though only one was usually seen in the comic run and the television cartoon. The Ratchet toy transformed into the second form. Ratchet was one of the original and the longest-lived of all Transformers in the Marvel Transformers comic series. Often a fan favorite, he was a healer first, but a soldier nonetheless. His courage and loyalty are demonstrated time and again. (continued on wikipedia)
