Dr. Percival "Percy" Cranial aka Dr. Badvibes is a brilliant, though completely deranged mad scientist. He used to work for Comtrex Technologies Incorporated, but he was fired for stealing top secret electronics and now he works for the Big Boss as his criminal genius. He has a glass dome on top of his head which shows his abnormally large brain and is known to create literal brainstorms by charging electricity through his brainwaves to form a cloud that can produce rain, thunder, and lightning.
