Crasher Casey

Casey or known as Crasher Casey is a human who appears in Transformers: Robots in Disguise who has a knack for competing in car sport events that end up being gate crashed by the Decepticons.

Season 1
A competitor in Smashdown, a demolition derby style event involving robotic vehicles, she was the reigning champion with her Triceratops-inspired Mechanosaurus, having defeated such vehicles as Truckalodon. However, her title would be taken from her after a confrontation with the Decepticon Groundpounder, whom she assumed was merely another driven rig. Casey actually performed surprisingly well against Groundpounder given his greater mobility compared to her rig, but was sabotaged by his Decepticon manager Headlock.

Season 3
She returns in Disordered Personalities. In the Crown City Grand Prix, four-time champion Casey found the race so routine and boring that she played a learning-to-speak-Spanish recording as she cruised in first place. She won the race, becoming the first five-time Ruler of The Roads, completely oblivious to the Stunticons' efforts to wreck her and the Bee Team's countermeasures on her behalf.
