Crusher is Blaze's biggest rival, an egomaniacal tractor-trailer who will do anything to beat the other racers to the finish line. When it comes to winning, no cheat is too big, and no trick is too underhanded for Crusher.
Crusher is egomaniacal, rude, selfish, whiney and a cheat. But he does have some honor. For example, once he learned a cake he wanted to eat was Darington's birthday cake, he felt that he had no right to eat it even though he really wanted to.
Crusher resembles a large 18-wheeler cargo-truck, such as a Peterbilt 386 or a Kenworth T680. He has a large silver grille, and is blue in color. His tire design features lightning bolts on them.
