12 WWE Monsters That Failed
2. Mabel
Another mid-1990s giant in the right place at the right time, Mabel was subject to the biggest heel push in the one-year title reign of babyface champion Diesel, gobbling up more time as a villainous challenger than Shawn Michaels, Psycho Sid or the British Bulldog in his ascent to the main event.
As 1995 King of the Ring victor in arguably the worst pay-per-view ever assembled by WWE, Mabel was a hugely destructive force, crushing Savio Vega in the final after giving the Undertaker his first televised pinfall loss in four years.
From there, the re-christened 'King Mabel' was unstoppable on television in the run-up to his SummerSlam main event against 'Big Daddy Cool', and was instrumental in the Davey Boy Smith heel turn that would set up the Champion's Autumn programme.
Truthfully, Mabel's rocket to the top wasn't out of place in the muddied waters of 1995 WWE, but it represented yet another deeply misguided creative decision from a Vince McMahon gradually unravelling in the wake of a resurgent WCW.
The industry had long tired of a Mabel-like figure in main events, and his de-push shortly after SummerSlam at least highlighted that lessons were being gradually learned.
