Jackhammer (Mutant)


 * Jackhammer is a mutant Cybertronian.



The wonderful thing about Jackhammer, is that Jackhammer's a wonderful thing. His head's made out of a piston, his lower body's a spring. He's bouncy, trouncy, flouncy, pouncy, and full of fun fun fun. But the most wonderful thing about Jackhammer -— as far as the Autobots are concerned -— is that he's the only one.

MUX continuity
When Autobots ventured beneath Valvolux, they were attacked by Mutants living there. The Autobots were forced to kill every Mutant there. Jackhammer himself was beheaded by Backblast.
