Firefly (Arkhamverse)

A pyromaniac, Garfield Lynns, AKA Firefly, began as a petty criminal but soon graduated to major crimes centering around arson, torching huge parts of Gotham City in the process. But his fires soon raged out of his 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.

Batman: Arkham Origins
Firefly is one of the assassins hired by Black Mask, who was later revealed to be the Joker, to kill Batman for $50 million. He is first seen at the assassins' meeting in the Royal Hotel along with Bane and the Electrocutioner, where Black Mask reveals himself to the Joker. After the meeting, he flies off to the Gotham Pioneer's Bridge, where he sets up four bombs. Later, after Batman discovers Bane knows his secret identity, he intercepts a broadcast from the GCPD about Firefly saying that he will activate the bombs if anyone but Batman approaches the bridge. Knowing that his bombs will put innocent people in danger, he goes to the bridge. He disables three of the bombs, one in the boiler room, one in the train station, and one in the south pillar. Afterwards, he confronts Firefly, and uses the Batclaw to take the detonator out of his hands. During the fight, Firefly finds the detonator, but finds out that the last bomb does not go off, as the GCPD bomb squad managed to get to the bomb before Batman. Enraged, Firefly chased Batman to the other side of the bridge. As Firefly tries to retreat, Batman latches on with the Batclaw, causing them to crash-land on a support of the bridge, where he destroys his jetpack and subdues Firefly, leaving him for the GCPD.
