Demolishor

Demolishor is cowardly when there's no leader, and he isn't the brightest one, but he's powerful enough to fight with multiple foes. He can use his excavator mode's tracks as wheels to travel (either as a unicycle or bicycle) and attack by moving one over his head to crush everything in front of him.[6] It should be noted that although Demolishor's alternate mode is a construction vehicle, he is not part of the Constructicon subgroup; rather, he is an individual Decepticon who happened to choose a similar guise to Scavenger (who is a Constructicon).

Demolishor protects a small Decepticon community in Shanghai after Megatron's death. He is the largest non-combined transformer seen in any of the Michael Bay films so far, although there are larger characters in the associated media.

Demolishor shares his model with another Decepticon, Scavenger. This led to confusion for several months by fans if Demolishor and Scavenger were the same character or different. In the film Demolishor is depicted as being primarely white, while Scavenger is red, but as Demolishor is seen only at night, his color is hard to see. Additionally most of the toys for Demolishor are incorrectly colored red, like Scavenger, making them nearly identical.

When the NEST and the Autobots come to Shanghai, China 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. Demolishor proceeds on a highway in China. He destroys an overpass just as Optimus Prime 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 while at the same time Ironhide damages one of his wheel joints in which breaks the wheel forcing the Decepticon to fall over, causing him to go off road and crash. With most of his body damaged as a result, Demolishor's last words are "This is not your planet to rule. The Fallen shall rise again" before Prime executes him by shooting him in the head.
