Firefly is Garfield Lynns - a man who was originally a pyrotechnic expert in the movie industry, but who became a victim of Gotham City's severe poverty and turned to crime. Displaying signs of pyromania, his crimes generally involve arson. He earned his Firefly moniker when Batman tried to stop him from committing a crime. He escaped the scene and, after he'd fled a fair distance, Batman thought he could see a firefly in the darkness - but it was actually Lynns' lit cigarette. Inspired, by this incident, Lynns took it on as a name. In an attempt to burn Gotham to the ground, Firefly suffered terrible burns after a chemical factory he set alight exploded. He burned ninety-percent of his body and he began his recovery in Blackgate Prison.
