#7 Vader

Vader is an interesting one. An all-time great in Japan and former three-time IWGP Champion and three-time WCW World Champion, Vader is one of the greatest big men in wrestling history.
In the mid-90's, WWE was having some pretty bad luck as many of their top stars were leaving for jobs with WCW. During this time, Vader would be one of very few to do the opposite, and join WWE.

With Vader being a major star and joining WWE at a time when they really needed him, you think that would lead to a monster push and tremendous run. Well, he did get a little push for a while, but Vader's run with WWE was incredibly underwhelming.
The rumor has been for several years now that WWE decided to stop pushing him because then WWE Champion Shawn Michaels felt that he was too stiff in the ring. This led to a diminished push that saw Vader eventually reduced to that of a jobber, where he was losing to everyone from Goldust to Bradshaw to newcomers like Mark Henry and Edge.
Vader would return to Japan shortly after his release from WWE, where he was able to revitalize his career, for a little while at least.
