Failed experiencents...(Danti)

Anti (experiencent 800AE) and dark (experiencent 666) where results of a failed experiencents from a company that made soldiers.
Dark was said that he was a mistake because he was a cold blooded killer and they call him a demon because how he acts.
Anti people say he has potential but he's just too insane so they treat him like a animal.
