Craniac is one of the smartest members of the Black Hole Gang. The other members being Brick Daddy, Jawson, Kranxx, Rench, Slizer, Snake, Squidtron, and Skull Twins. He looks a lot like the Skull Twins, but he's got a different face. He drives a speeder and is said to be very greedy. He has yet to appear in another set apart from the Summer 2010 set, Space Police Central.
Craniac is the master planner of the space-crook gang. If there's a daring heist, a high-tech break-in or an impossible escape from Space Police hyper-jail going on, you can bet that this is the guy responsible for working out the whole thing-and with his cybernetically-enhanced brain, he makes it look easy. Craniac might be a little too smart for his own good, though, and Brick Daddy keeps a close eye or three on the loot to make sure his smartest henchman doesn't try to pocket any of the gang's ill-gained goods for himself. After all, that's the boss' job!
