[@knifeman] As a child, he was bad at hiding his ghoulishness, and humans kept trying to attack him because of that; as a ghoul, he always came out on top, increasingly so as he grew older, until eventually a large gang of ghouls beat the crap out of him, using the number of gang members he incapacitated before going down to decide whether or not he should be allowed to join them. And so he did, and now he's part of a ghoul street gang, and still bad at hiding the fact that he's a ghoul. Boom.
