Ellis, the Devil's Own

The crowning achievement of Project Inferno is perhaps the most unfortunate superhuman in history: Ellis, the Devil’s Own. He may or may not have been a Scottish nobleman named Andrew McBain, who discovered his powers when he was burned at the stake as a witch in the 16th century, and who came to America as a member of the Roanoke colony where he fell under the influence of the demon Croatoan. He has spent much of the last eighty years being kidnapped, tortured, vivisected, and cloned while scientists tried to mold him into the perfect living weapon, making Ellis’ memory and sense of identity (and sanity) tenuous, at best.
In addition to superhuman speed, ferocity, and immortality, the Devil’s Own can superheat his fingertips, which burn anything he touches, often raking his enemies with his trademark burning slashes. He also regenerates slowly, wounds “burning” away—unless he’s also set on fire, in which case he heals even faster, although it still feels like he’s burning.
