An evil abomination of a masked man.
Back story: Your everyday Steve is sitting in his house cooking pork. He felt like he needed to show off his fighting skills(But they weren't very good.). That night a skeleton walked by his window, trying to skewer him through the window panel. As Steve laughed hysterically and the skeleton's plight, he realized that if he proved he could defeat this skeleton, he might be revered a bit more. He needed proof though, so he decided he would take a fragment of the skeleton's skull and fashion it into a mask. The decision was made to trap the skeleton, because he felt a bit tired for straight on fighting. After cobwebs were rigorously placed all over his east wall, he lured the skeleton after him. While the skeleton was writhing in webs, the man, frightened slightly, decided not to kill it, and just took the skull and bashed in on a rock, and took the largest fragment. When a mask was fashioned, he placed on his face and admired himself in the mirror. He looked very intimidating, and heroic too. But then, his mask began to quiver. It shot to his face and clamped down, spreading tendrils of another conscience through his mind and quickening Steve's pulse. He then realized his mistake, he should have killed the skeleton first. A bit if the skeleton's mind was still in that fragment. And that mind only thought one thing. Kill. The consciences of the two beings began to merge, along with other features. He lost his hair, his skin paled, and veins bulged on his face. The result of these minds was a hideous abomination, an evil mind that still wanders today.
