[@Rune_Alchemist] Thanks for the heads up, I look forward to seeing it!

[@Inertia]Is his Quirk "producing a spark" or "adjusting oxygen density?" An individual can only have one power, even though the power might be a combination of their parents'--for instance, someone with fire manipulation and someone with ice manipulation might have a child who manipulates temperatures as a whole--but it is, in essence, still just "one quirk."

I'm not a science man so I don't really know for sure, but it seems to me like you could bundle it all under "adjusting oxygen density" and have the initial spark be the result of super-dense gaseous concentration around his hands creating enough friction to generate ignition. But that would also mean that anything else, not just his own movement, could possibly generate the ignition for the explosion as long as that person is within the high-concentration area.
