10 Most Memorable WWE Mystery Opponents

10. John Cena (SmackDown 2002)

Like another legendary WWE superstar and future Hall Of Famer, John Cena began his WWE career as a mystery opponent. An open challenge would be issued by Kurt Angle in which Cena answered and fought valiantly before falling to double-arm pinning combination.

Following the match, Cena was congratulated on having such a fantastic, competitive contest with the Olympic gold medalist by numerous WWE legends, with the most important and memorable stamp of approval coming from The Undertaker.

As everyone that is reading this knows, Cena went on to become one of the most successful superstars in WWE history, even adopting his own open challenge in 2015 as WWE United States Champion.

While his career is no doubt far from over (the 15-time world champion is likely to break Ric Flair's world title wins of 16 before he calls it quits), it all began on the big stage as Kurt Angle's mystery opponent.
