Hm.. I might make some changes then. Maybe something like Crossfire or Black Knight (Nathan Garrett)

Just because FFF is fictional in-universe doesn't mean he can't be a character. Doctor Faustus exists both as Johann Fennhoff and the fictional novel character. Plus the fictional character could always be based on a true myth.
