Bonecrusher

Bonecrusher is a Decepticon who appeared in the first Transformers movie. Bonecrusher is aggressive and incredibly hateful, even moreso than the other Decepticons. He hates everything, even himself, and hates Megatron but would hate to get terminated so he works for him still.

Bonecrusher is first seen hiding in a motor pool in a military base when he was called by Starscream to converge on the All Spark. He left the base and met up with Barricade and Brawl. The three Decepticons saw several Autobots, including Optimus Prime. Barricade was the first Decepticon to charge into battle. Seeing Optimus, he knocked other cars aside before transforming into his true form and knocking Optimus off the bridge. He punched Optimus, only to get punched back so hard his eye popped out. He fell off the second bridge. When Optimus jumped down to fight him, he swung his claw wildly at him, and Optimus took his sword and ripped off Bonecrusher's head, killing him.
