Rollbar is an Autobot who was originally intended to be in the Dark of the Moon film - though this was a misunderstanding. At around July 2010, a Transformers fan brought a red, customized jeep to the filming set of Transformers: Dark of the Moon. Fans thought that this was a new Autobot - but the film's cast confirmed that it was brought because the fan was hoping for it to be included at the last minute, though that didn't occur. Ultimately, the character was never used in the film, nor in any part of the Dark of the Moon franchise.
