Your character has inhuman strength and agility that allows him to break bones and run faster than the eye can see, can consecutively use more than seven high-tier magic attacks with no fatigue whatsoever, defeats heartless without a weapon and is a master of ten martial arts? Right now, your character's really, really overpowered. I'm not even kidding. :P

P.S
Did you copy your character's name, personality and powers from the Hunter x Hunter character Killua? I even saw that you mentioned Kurapika in your post.

My app's going to be finished soon. :P
