About Firefly

Firefly is the alias of several supervillains appearing in American comic books published by DC Comics. Created by writer France Herron and artist Dick Sprang, the first and best-known incarnation of the character, Garfield Lynns, was introduced in Detective Comics #184 (1952). Initially depicted as a gimmicky stock villain who utilized lighting effects to commit crimes, Firefly was later reimagined as a psychopathic pyromaniac with an obsessive compulsion to start fires following Crisis on Infinite Earths' reboot of the DC Universe in the 1980s. This darker version of the character has since endured as one of Batman's most recurring enemies and belongs to the collective of adversaries that make up his central rogues gallery. Other characters have also adopted the Firefly persona, including Ted Carson and Bridgit Pike, an original female incarnation introduced in the television series Gotham who was later integrated into the comics as Carson's protégé Lady Firefly.
