Ratchet is the chief medic of the Autobots in the Transformers cartoon and comic series based on the popular toyline 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.
He was voiced by the late Don Messick, who also was the original voice for Scooby-Doo. Wally Blur once voiced him in Masquerade.
Ratchet was the Autobot medic, and therefore he seldom was ever seen in battle. He usually spent time at the Autobot base with Wheeljack creating and repairing other Autobots. The two of them were credited for creating the Dinobots in an attempt to bolster their ranks versus the Decepticons.
Ratchet was eventually killed in The Transformers: the Movie in an attack by the Decepticons on an Autobot shuttle. The Decepticons penetrated the hull of the shuttle that he, Ironhide, Prowl, and Brawn were flying in. Ironhide and Ratchet attacked the invaders together after Prowl and Brawn's death. The two suffered the same amount of fire from the Decepticons; due to Ironhide's strong armor, he survived the first strike but ultimately died. Ratchet, on the other hand, was killed easily. Luckily, his role as medic is taken by Junkion leader Wreck-Gar, who formed an alliance with the Autobots, and First Aid of the Protectobots.
