It's a large file, but I'm still giving an even LARGER love for the guy! <3 So, since his wings absorb heat, can he theoretically burst his wings on fire if enough focus going through it? Like, turning a Phoenix?
That would be interesting, but I don't think he would do that intentionally. As he isn't immune to his own flames. But that is the general jest of how he can fly, he "sheds" the heat off the feathers in the direction he wants to apply thrust. I can assure you this still has resulted in many broken bones and injuries.
