Garfield Lynns (Earth-3846)

Early Life
Not much is known about Garfield Lynns's childhood, save that his irresponsible single mother left flammable objects within his reach, leading him to develop pyromania later in life.

Pyrotechnics Career & Becoming Firefly
In his adulthood, Garfield found a healthy outlet for his pyromania as a pyrotechnics engineer. His first job was as a special effects engineer for Panessa Film Studios, but was unceremoniously laid off after his only film, The Inferno, turned out to be a financial flop.

At some point, Garfield was hired to oversee the effects for the rockstar Cindy Cooke's live performances. The two of them began dating soon after one of her shows ended, and Garfield became obsessed with her, to the point that he started stalking her and making unwanted advances, even at work.

Cindy eventually decided Garfield was a bad influence and cut him off. Garfield was infuriated, and secretly rigged the pyrotechnics at her next show to explode and burn down the whole stadium. Though his plan ultimately succeeded, Lynns got caught in his own blaze, scarring over 90% of his body. He repeatedly refused medical treatments for his scarring.

Upon his release from the hospital, Lynns fled for the slums of Gotham, where he came across an abandoned GothCorp warehouse filled with experimental military equipment, including a flamethrower and jetpack. Lynns stole the stash of equipment and set out on a spree of major arsons around Gotham.
