"You'd better what your words Foxboy, I've got a thousand different ways I can make my ability very frightening and dangerous, don't tempt me to start trying them all out" he growled angrily. His temper was a side effect of his gift, he was more feral and a little less in control which is why he had to develop great restraint when he was younger so that he didn't hurt people.
