Captain Fission

Captain Fission is the oldest working hero to date, and the founder of The Vanguard. He does not claim to be the strongest, but he is the brains behind the organisation, while Warlock is the brawn and Connor McNulty the money.

History
Nothing is publicly known about his personal life, though according to The Vanguard database, his name is Roger Orr and that he was born in Maryland some day in 1943. Anything else on him must be at a higher level of clearance than what you can obtain...

He posseses one of the world's only known functioning power suits, which was gifted to him in 1977 by McNulty Biomedical Engineering. It has a built-in atmospherics system, filtration system, night-vision eyewear, lightweight armour and nervous system enhancers, which increase his overall reflexes and strength by about threefold.

Power
Captain Fission's power is Molecule Manipulation, allowing him to freely manipulate any kind of matter on a sub-atomic level. Due to Aura, however, this power cannot be directly used on opponents and must be used on the environment around them.

Due to his power's... Unfortunate side effects. Captain Fission cannot be around other people without his power suit, nicknamed "MANHATTAN" by him, or else they will eventually suffer a fatal dose of radiation.
