Heretostay123 - I quite like your ability, however I think it needs to be explained just a bit longer. You say, "if he concentrates long enough" when talking about transmuting an object - perhaps you can make an estimate? Does the change last forever on those or do they revert back?
JNathan - I think with Nathan we need to reign back on the offensive. How about, instead of manipulating fire he is very fire resistant?
Khawill - Love this signup, clearly a lot of thought gone in to your power. However, I don't think the clone/robot is necessary.
