Demolishor



Demolishor is a monstrous, gyroscopic unicycle of death. Demolishor's personality is described as thick-headed. He is cowardly when the Decepticons don't have a leader, because he is used to being ordered around by Megatron. Demolishor is also the guardian of a small Decepticon community.

Revenge of the Fallen film
When NEST and the Autobots come to Shanghai, and China are attempting to uncover a hidden Decepticon, they find Demolishor and Sideways. Demolishor transforms and swats at NEST helicopters as he begins to make himself mobile. He then proceeds onto a highway. Ironhide chases him, but has little success, so Optimus Prime is released into the fray. Demolishor destroys an overpass just as Optimus transforms and jumps off the bridge. Optimus manages to dive onto Demolishor, grabbing onto his face as he proceeds down the highway. Optimus shoots him repeatedly, forcing the Decepticon to fall over the edge of the highway and crash into the ground. As Optimus and Ironhide approach him, he declares that "The Fallen shall rise again", after which Prime shoots him one final time in the head.
