Airwave
If crime didn't pay, Airwave would be out of a job. Before the Cybertronian Civil Wars, he was an airbase inspector, charged with finding and reporting stolen and contraband goods... but if you greased his palm a little, he gladly looked the other way. When the Decepticons started their smuggling operation, Airwave happily signed on—as long as Megatron kept letting him play the black market.
Eventually, he was put in charge of a Decepticon airbase, and proved himself an able (if a tad sadistic) commander. However, his petty scams and swindles have earned him the enmity of his fellow Decepticons, who'd gladly sell him for scrap if Megatron didn't need him.
