One Piece- The Split Personality

Jade Parker wasn't your average kid, he was actually a sort of anomaly, one that was one of a kind. He possessed two different personalities!! While this may seem rare but far from special, the part that made him unique was what triggered the second personality. The word "Kill." The second personlity was that of a complete and total cold blooded sociopath capable of learning and adapting in mere seconds. It was truly a ferocious existence that defied logic and reason. Jade Parker was on his way home from his highschool one day when someone ran up and shot him from behind. It wasn't anything out of the ordinary as the neighborhood he lived in was crawling with crime. He died without knowing what happened to him.
