A result of a CT scan gone wrong. When an innocent young man was having a CT scan, everybody that checked the equipment failed to notice a little criminally insane (he he) lightning bug stuck there. So when the machine started up, the mans and the bugs DNA melded to make one super-being. And from that day forth, he terrorized the whole city (by means of his pyrokinesis and flight powers), blaming everybody for what happened to him.
