Neoki: Dark Form

A concept I've been working on for a little while now. What if, because of the evil and obscene deeds done by Agony(Neoki's evil half of his soul), Neoki was tainted by darkness and coul assume this form: The Dark Form. In this state, Neoki would become malicious and have nearly no emotion whatsoever. A form perfect for slaying demons, in my opinion. His special technique in this form is the Dark Photon Cyclone, a variation of his normal technique Photon Claw. The attack forms an aura of weaponized chi that surrounds Neoki and tears apart anyone that is not within the cyclone. comments??
