Dude.. Thats kind of missing the point.How about when he a specific strike it can melt steel, but that takes energy to keep up that sort of heat. Otherwise he just isn't susceptible to physical damage!

Except there are other things that aren't steel...

Fine. He can melt steel by blocking it. But other, stronger materials are almost completely ineffective.

Can he manipulate concentrated fire? Like, charge up a fire beam for some posts then boom lasers.
