An old demon named Anung Un Rama, Hellboy was brought to Earth as an infant by Nazi occultists. He was rescued by Allied forces and raised by the United States Bureau for Paranormal Research and Defense (BPRD).
He grew-up to be a large red-skinned demon with a tail, horns, (which he files down to stumps) and a big stone right hand.
Although a gruff anti-hero, he shows none of the malevolence thought to be intrinsic to demons and works with other strange creatures in the B.P.R.D.
He has been dubbed the “World’s Greatest Paranormal Investigator.
