#2 Test
Test should have been a bigger star. I mean literally, he was planned to have a WWE Championship run in late 1999, replacing Steve Austin at Survivor Series and to feud with Triple H. Instead the Big Show took his place in the Championship match, while Vince McMahon did, in the Triple H feud.
Test went on to be a WWE Intercontinental Champion, European Champion, Hardcore Champion and Tag Team Champion, but was still never utilized to his full potential. He was released by WWE in 2004, only to return in 2006 for a brief main event run in WWE's version of ECW, before being released again in early 2007.

Following his release, Test came to a verbal agreement with TNA. He debuted as a face for TNA in August 2007, under the name 'The Punisher' Andrew Martin. At the Hard Justice event, he teamed with Abyss and Sting to defeat Christian Cage, Tomko and AJ Styles in a 'Doomsday Chamber of Blood' match. This would be Test's one and only match for TNA, as he parted ways with the company a few days later. The believed reason was that TNA management were worried about his freakishly enhanced size.
Sadly, Test passed away on March 13th, 2009, four days prior to his 34th birthday. His death was ruled an accidental overdose of oxycodone.
