#4 Lex Luger
It is surprising that Lex Luger never won a title in the company despite being heavily pushed in the 1990s. Luger was the heir apparent to Hulk Hogan, with an elaborate segment of bodyslamming foreign heel Yokozuna on the USS Intrepid supposed to catapult him to babyface superstardom.
This was followed by the 'Lex-Express', which was a tour bus in which Luger went all over the country winning over fans. However, the crowd did not warm up to him in a way that the WWE wanted. He did co-win a Royal Rumble alongside Bret Hart, which makes him the only Rumble winner never to win any title in the WWE.
He lost to WWE Champion Yokozuna at that year's Rumble and soon made his way over to WCW, where he won the WCW World title multiple times.
