Garfield Lynns (a.k.a. Firefly) is a villain from the Batman series. He is a pyromaniac, but during one of his fires he got caught in the flames. He has several severe burns across his body, and now wears a flame-retardant suit to keep this from happening again.

Batman Arkham Origins
Along with seven other assassins, Lynns was offered a fifty million dollar reward if he were to kill the Batman on a Christmas Eve night by Gotham's most feared mobster, Black Mask.

He planted a quadruplet of bombs around a Gotham bridge in order to lure the Bat out of the shadows. It was successful, forcing Batman to visit the bridge, but the bombs were quickly disabled and Firefly himself was defeated, having his scarred, burnt face revealed via a visor cracking family of punches that knocked the pyromaniac unconscious and ready to be arrested by the GCPD.

Batman: Arkham Asylum
The Firefly doesn't appear in the game Batman: Arkham Asylum. One of the Riddler's riddles revolves around him. He has an entry in the Character Bios. His profile states: A pyromaniac, Garfield Lynns began as a petty criminal but soon graduated to major crimes centering around arson, torching huge parts of Gotham in the process. But his fires soon raged out of control, leaving him horribly scarred by one of his own blazes. His body is almost fully covered with burns, and he now wears a full-body flame-retardant suit when he’s out pursuing his criminal interests between bouts of incarceration in Blackgate.
