Well this is a fan characters for a series of books. Not sure what the sereies is called but the three books are. In the Garden of Eden, Sky Coyote, Hollywood Mendoza. Basically a company goes back in time and makes immortals to walk forward through it normally sending lost relics forward as they go. Nent here is a half Neanderthal and his immortality procedure had a glitch. The gene that stops there aging kicked on too early. So he had to have all custom jobs on his new unbreakable cybernetic bones. Nent here is seen in one of the company's Rome bases. He didn't have much of a mortal childhood so he's enjoys some babytime when he can. He's actually diapered under that waist cloth. He can turn his control on and off at will. Lucky lil immortal.
