Skulker, The Experiment

This is Skulker, from a fanfic that I'm planning to make. Skulker gets out of the Ghost Zone and is captured by the Men in White and his soul is transplanted to a new body, a body of a freshly dead fifteen year old boy. Skulker is now a half-ghost, and is made into a M.I.W. operative.
Meanwhile, Danny Fenton's 1-month younger cousin, Saithia (known as Sai), is moving in with Danny because her parents, who are also ghost-hunters died in a hunting accident. Sai and Danny get along fine, for she is a half-ghost, and Sai is especially close to Sam. During summer vacation, they encounter a boy named Pierce Rekluks (spell Rekluks backwards). Well, if you did the spelling thing, Pierce turns out to be an attractive Skulker who just happens to be hitting on Sai. Perhaps a friendship between Skulker and Danny will be formed to defeat a very powerful enemy. And Wulf returns...and he just happens to be Sai's best friend!!!
