Well, his archenemy is an Ice-Man.
Well, it's more like he produces it from his body. Given that there are characters with magma powers in other works that's basically producing molten rock from their body, I figured being able to produce ash from your body wouldn't be too far fetched. I'm on the fence on whether he can control fire/ash that's not form his body.
So far, he can burn people by hitting them with burning ash, produce shields, soothe, create pathways (once it's cools down a bit which he can do with his powers) and stuff. He can control with it his will so he can hold them together so they don't break apart easily.
I once did change it to fire powers but changed my mind and went back to my idea that he controls ash. His archenemy using ice powers, I felt that the audience would end up being more drawn towards his fights because he will be doing all sorts of creative stuff with ice whilst the MC would just be shooting fire balls. That didn't seem right and fire-shields and stuff never really worked for me and I thought the will-controlled ash was a better idea.
He also has a secondary form where he basically becomes this walking skeleton that's on fire and he can produce even greater amounts of burning ash and is immune to injuries. Basically, he can stabbed, blown up etc, etc but he would just reform back. Mind you this form still has it's limitations.
I'm thinking of keeping the magic explanation for his clothing since he's down in the dumps and poor at the start of the story.
I'll think about him having some control over carbon. That sounds like an interesting idea.
Also the guy is also a chain smoker but I want him to be immune to the effects of smoking due to the effects of his powers. I mean not completely though, it's more like the effects show up a lot later on him than normal people who smoke.
This is completely out there and I want to provide at least some explanation as to how that might work. I'm thinking that the whatever process is automatic though not a healing factor, since I'm not a big fan of that trope. Anyone has any ideas?
