12 WWE Superstars Who Made It Big And Then Just Disappeared 

4. Jeff Hardy

Jeff Hardy has held nearly every title that WWE has or had to offer: Tag Team, Light Heavyweight, European, Hardcore, Intercontinental, World Heavyweight and WWE Championship. Some fans referred to him as HB2K as a play on the year 2000 nickname and the fact that he was being compared favorably to Shawn Michaels (HBK) as a future main event superstar. But it took a while, and a long and winding path, for Hardy to reach that main event plateau. Wellness policy violations derailed him a couple times. He left WWE in 2003 after six years in the company and stopped over in TNA for a couple years before making his way back in 2006. It was during this run that he finally realized his potential with a main event run in 2008-09 that included three title reigns (one WWE Championship and two World Heavyweight Championships) and a hellacious feud with CM Punk over the WHC. Unfortunately, that feud was also Hardy€™s exit from WWE, as he lost a €˜loser leaves WWE€™ steel cage match against Punk, ending a hot feud and sending Hardy back to TNA, where he€™s been since. Any time a wrestler is a world champion one day and leaves the company five days later, it€™s just about the biggest Houdini act you€™ll ever see.
