Dr. Faust (Guilty Gear)
The doctor is in, and he’s patently insane. This nine-foot-tall maniac didn’t always wear a paper bag over his noggin, though. Before losing most of his marbles, he was Dr. Baldhead, a genius physician renowned for his medical prowess and healing power. But when a little girl mysteriously died during one of his operations, he blamed himself and was consumed by guilt. That guilt grew into full-on madness, spurring Baldhead to take up a gigantic scalpel and murder strangers for seemingly no reason.
But why does he wear the mask? To atone for his sins and reform his identity. After a visit from the ghost of the girl who died under his care, who explained that her death wasn’t his fault, Faust shed the serial killer persona of Baldhead and endeavored to save lives instead of ending them. From then on, his moves took on a more comedic tone, and he somehow developed powers of teleportation. The lesson here, kids, is that wearing a paper bag over your head builds character.
