The Pyromaniac

Created by Charlie in 2015 and originally called Fire Man, the Pyromaniac is aman who uses fire to kill random people.

Creation
The Pyromaniac used to be a bomb maker, but when he was betrayed by his boss he was set on fire and left to die. The Order of the Shadow Monks threw science goo on him, which fused his body with the flames.

In Film and TV
In the film The Four Mad Men: Wrath of the villains, Pyromaniac breaks out of prison with Stone Heart, Puku Nuku, Hokey Pokey, Venom and Changer. He was very dangerous, but in the end he was put in a giant freezer which changed him back to a human. I don't know how that works.

In the TV Show The Four Mad Men Origins, Dean Wolfenstein was a bomb maker, but when he was betrayed by his boss he was set on fire and left to die. He did die, but The Order of the Shadow Monks resurrected him. He created a flame suit and got revenge. Near the end of Season 2, he has science goo thrown on him, and this turns him into the real Pyromaniac.
