Carbon Man

Carbon Man is a human who figured out how to control the bonding of carbon on a practical (large) scale, was able to make any form of carbon in any shape, and as such built a suit of mechanized and weaponized armor made completely out of various forms of carbon. The suit’s armor consists of layers of graphene and nanotube shock-absorbers, the suit’s guns shoot diamond bullets or flaming charcoal, etc., and the entire suit is incredibly strong and light, and the graphene has adjustable transparency. Carbon Man is a reserve member of the SuperNaturals but does a lot of other superhero work on his own.
