I would argue that Rurik's abilities are somewhat heat related (energizes/excites things to the point that they explode), but not in a way that would clash with something intended to be directly heat based. I only mention this so that it doesn't become a point of contention later.

Basically I'm trying to say "sounds good, please don't be upset later when you see my guy's powers in action." XD
