#3 Raven's Seven Deadly Sins
He may be known as one of the most creative minds behind the scenes in wrestling, but Raven didn't exactly set the world on fire in WWE.
Joining as part of the Invasion, the former WCW and ECW star was a solid mid-carder as part of the Alliance, but once that ended he found himself almost permanently on Heat.
During the C-Show though, Raven would form his own gimmick, where he would try to coerce lower-tier Superstars into committing the seven deadly sins.
As he had been the leader of the Flock in both WCW and ECW, it seemed likely that this could've worked.
Mid-story though, the angle was dropped, for reasons still mostly unknown.
Instead of being this interesting character, Raven went back to doing nothing of importance on Heat, before his release.
