History: Though a physical clone of the original Fireman, the Mark II version's mental patterns were originally programmed to resemble Heatman of Wilys Warriors. Giving him the Warrior's cunning and resourcefulness but without Heat Man's sociopathic and homocidal tendencies. However, due to some accident in the lab, the newly awakened Ben suffered permanent brain damage and making him extremely unbalanced. At one moment he's one of the Six's top warriors and then he's a raving madman that can destroy city blocks before calming down. In spite of Dr. Light's attempts to repair Fireman's damaged neuro-circuitry; his visions of the malevolent "Muffin Man" persist driving Fireman into fits of madness and rage. Though a valuable asset to the Sinister Six, Fireman can often be a dangerous and unpredictable liability.

Powers: Equipped with two powerful flame cannons that can melt through a 6-inch steel wall in a matter of seconds or pulverize an entire forest with a wall of infernal conflagration. Or by supercharging the flame that makes of his 'hair' Fireman can create a raging inferno that can fry any robot within his range.
