#5 Rob Van Dam

Rob Van Dam is arguably one of the most loved and over superstars' of all time and his return at the 2009 Royal Rumble match speaks for itself. Having established himself as one of the all-time favourites, thanks to his classic matches under the ECW banner, RVD is definitely one of the best high fliers of the game.
In 2007, RVD had competed in his supposed last match for the WWE, only to return to a triumphant ovation two years later at the Royal Rumble match. In his return match, RVD stuck to his natural game and stunned the entire WWE Universe with his all-around high flying skills.
RVD once again took some time off from the WWE and made his eventual return at the 2013 Money in the Bank pay-per-view, as one of the six entrants in the Ladder Match to determine the Mr. Money in the Bank.
With the 2019 Rumble match approaching, I'm pretty sure the WWE Universe wouldn't mind another special appearance from RVD.
