The main villain of the piece. A pyromaniac committed to Arkham Asylum, before being broken out by a mysterious ninja operative and set loose upon Gotham. While he's always been enthralled by the destructive power of fire, recently he's become a fanatic, ranting about the need to "save" Gotham from some unimaginably dangerous force of darkness, through the power of his "purifying" flame.

He's manic, obsessive. But not cruel. This interpretation of Firefly sees himself as almost a prophet and a savior. Think of a screaming preacher in a suit of high-tech armor, proselytizing about the wonders of flame and the dangers facing Gotham.
