Firebug first appeared in "Batman" #318 (December 1979). Joe Rigger was a soldier and demolitions expert who returned to Gotham City when his family had been killed in three separate building-related accidents. His sanity slipping, Rigger vowed that those buildings would not kill again. Using his military training and a costume containing tanks of napalm, he became the Firebug and set out to burn all three buildings to the ground. He was defeated by Batman atop the towering Gotham State Building, and believed dead after his tank exploded.
