Ka-Ching

Chisel is the greediest Decepticon in Megatron's army. If you have one of something, he'll want a hundred more. While this attitude often puts him at odds with other Decepticons, especially those in his Dread squad, he will defend what is his with a psychopathic vigor that makes him a nominal choice for resource transportation. Chisel would rather extinguish his own spark than lose even one small piece of his "collection."

The elusive Superfund truck [link] from "Dark of the Moon" may have just been a human vehicle flying the 'con colors, but that won't stop me from guessing at what may have been.
