Kriegs abilities

OK so he has physical strength higher then the Celestia or Luna. He takes almost no damage while on fire and becomes stronger. He can breath fire out on to other things and when on fire make orbs of fire to hurt stuff.. When he kills something it can explode into energy to kill others. When damaged heavy he is able to mutate, causing a full regeneration, a massive strength increase and becomes why more harder to damage. The more things he kills in a row, the more damage he can deal. And killing stuff can heal him if it is harmful enough.

Anything not mentioned in the story yet is unknown to ponies.
