Obviously inspired by the flame throwing prowess of Pyro in the X-men, Everett Bradford designed a system that mounts on his wrist and propels fire when he moves his hand back. The flame is ignited through a fuel can at his waist.
It looks pretty awesome too and I bet he could impress Rogue and Storm enough to score, but it is potentially fatal should he spring a leak. You can tell that he is feeling the intense heat on his hand and cant run it too long. The combustion mechanism is complex and he has a second video for a detailed explanation, but I wouldn’t try this at home. Creating fake mutant powers could prove very dangerous. Cool, but dangerous.
