From the modder's records: The Human Flame is an old Martian Manhunter villain who went 50 years between appearances. Made for a friend of my venue's judge, the Human Flame is made from a Danger Room Cyclops. His costume is lumped out with green stuff. His flame spurts are made from a couple of Horrorclix Firebreather flames. He is on a Checkmate Knight (Black) dial from Brave and the Bold with a custom character card (with a Trait that nerfs DC Martian characters and adds 15 points to his total)."
If you don't know who he is, click on the "Human Flame" label at the bottom of the post.
