Wheeljack (also known as Que) is an eccentric Autobot inventor that appears in Transformers: Dark Of The Moon. He is responsible for developing many of the weapons used by NEST against the Decepticons.
Late in the film as the Autobots battle their way through 'Con-occupied Chicago, Wheeljack is among several Autobots captured by Soundwave. Wheeljack pleads for mercy, only to be shot in the back by one of Soundwave's troops, then finished off by Barricade.
The original incarnation of Wheeljack from the Transformers cartoon was also a talented inventor and one of the more popular characters of the series. Unfortunately in Transformers: The Movie, he makes only a brief appearance on-screen and is already dead, his body laying beside Windcharger's.
