7. Ken Shamrock
We haven’t seen “The World’s most dangerous man” in the WWF/E since 1999, so this would be a surprise entrant that would shock the wrestling world, to say the least.
Hardly anyone could argue that this former UFC World Heavyweight Champion & WWF Attitude Era Veteran belongs in the WWE Hall of Fame, so a 1 night return in this years Rumble match would be the perfect way to bring him back before he gets inducted in a year or two from now.
Shamrock is still in excellent shape and could easily work the match.
6. Rob Van Dam
RVD’s last Royal Rumble surprise return in 2009 got quite a big reaction, so it’s safe to say that the same thing would happen if he’d return for this years Rumble match.
He still keeps himself in shape and occasionally wrestles on the indy scene, but has yet to return to the WWE after leaving in the summer of 2014.
