Ratchet is a sentient alien robot (commonly known as a Transformer, or a Cybertronian) from the planet Cybertron. He was introduced in "The Transformers: Generation 1" (1984), and was originally going to be a female. He is a medic, and named after Nurse Ratched. (from One Flew Over the Cuckoo's Nest)

In the fandom, he is known for having a grouchy attitude and also throws either a scanner or tool (usually a wrench) when pissed. Tends to curse quite a lot as well.

This grouchy attitude becomes cannon in Transformers Animated, and makes a return in Transformers Prime.

He is usually red/rust orange and white with blue eyes, though the exception being the Micheal Bay movies in which he is a lime yellow/lime green. Fans still fight over this, though he seems to appear as both depending if it's games based on the movies, or the movies themselves.

He always takes the form of an ambulance, the only exception being the Micheal Bay movies in which he is a hummer. (Though seems to be modified to be some form of an ambulance)
