Mudflap (Demolishor) was an Autobot mentored by Landmine who was among those who evacuated from Cybertron and went into hiding on Earth. Growing dissatisfied with the Autobots' mission and human customs, he was persuaded by Starscream to join up with the Decepticons in a misguided attempt to try and save the galaxy without worrying about the affairs of humans.
However, he found he could not stomach the Decepticon way of doing things, and ultimately left them; consumed with guilt over what he had done, he was given a second chance and welcomed back into the Autobot fold by Landmine. He speaks with a French accent.
Mudflap transforms into a truck crane. His Cyber Key extends his crane arm and deploys a massive saw blade (Mega Crane Blade), and also activates an arm-mounted missile-launcher.
