#1 Lex Luger
Back in 1993, Yokozuna was running rampant on the WWE's main roster. No one was able to put him down, but a freshly turned babyface Lex Luger, did the unthinkable and bodyslammed Yokozuna. He went on to face the behemoth at SummerSlam 1993, and won the match via countout. According to reports, Vince McMahon didn't feel that Luger was drawing audience, hence the push didn't move forward.
Luger returned to WCW in 1995, in one of the most famous moments in wrestling history. The US Heavyweight title match between Ric Flair and Sting on the premiere of Nitro saw Luger making an appearance, to the shock of the fans.
He was a major name in the promotion during the Monday Night Wars, and remained in WCW until the company was bought off by WWE in March 2001. Luger wrestled his last WCW match at the final WCW PPV named Greed, where he teamed up with Marcus Bagwell. The duo failed to defeat Chuck Palumbo and Sean O'Haire for the WCW Tag Team titles.
