A half-demon whose true name is Anung Un Rama ("and upon his brow is set a crown of flame"), Hellboy was summoned from Hell to Earth as a baby on October 5th by Nazi occultists (spawning his hatred for the Third Reich). I was discovered by the Allied Forces; amongst them, Professor Trevor Bruttenholm, who formed the United States Bureau for Paranormal Research and Defense (B.P.R.D.). In time, Hellboy grew to be a large, red-skinned adult with a tail, horns (which he files off, leaving behind circular stumps on his forehead), cloven hooves for feet, and an oversized right hand made of stone (the "Right Hand of Doom"). He has been described as smelling of dry-roasted peanuts. Although a bit gruff, he shows none of the malevolence thought to be intrinsic to classical demons, and has an ironic sense of humor. This is said to be because of his upbringing under Professor Bruttenholm, who raised him as a normal boy.

Hellboy works for the B.P.R.D., an international non-governmental agency, and for himself against dark forces including Nazis and witches, in a series of tales that have their roots in folklore, pulp magazines, vintage adventure, Lovecraftian horror and horror fiction. In earlier stories, he is identified as the "World's Greatest Paranormal Investigator"
