Real name: Garfield Lynns
Appeared in Batman: Huntress/Spoiler: Blunt Trauma
He escaped from jail during the Gotham earthquake along with Stephanie's father. He attempted to take on Huntress and Spoiler, but was quickly defeated when they worked in tandem, Stephanie finishing him off by dropping a cash register on his head.
Firefly was lucky Stephanie was around, because she had to convince Huntress to save Lynns from being burned alive in his own flames. At her insistence, they dragged Firefly out of the burning store and dumped him in a fountain. Huntress was not happy.
