5 WWE Superstars whose careers failed to take off despite being crowned King of the Ring 

#2 Mabel - 1995

Mabel

After almost two years of playing the role of a positive babyface rapper with the Men on A Mission faction, Mabel would turn heel in 1995.

His new thug heel persona was soon followed by a monster push that saw him briefly enter the main event scene, and it all started when he won the 1995 King of The Ring. There were allegedly plans in place for Mabel to become WWE's new top heel, as his push continued when he was announced to face Diesel for the WWE Championship at SummerSlam that year.

Mabel would lose to Diesel in a critically panned match, and soon lost his main event push. Mabel went right back down the card and had various mid-card feuds until he left WWE in 1996. He returned under the name Viscera in 1999 for a year, before being released again in 2000. He returned again in 2004 and had a four-year run as a top mid-carder, wrestling as 'Big Daddy V'. The height of which was unsuccessfully challenging for the WWE ECW Championship on occasion.

Sadly, the man known as Mabel, Viscera and Big Daddy V, Nelson Frazier Jr. died of a heart attack just four days after his 43rd birthday in 2014.
