During his reign of terror, Kimbo Slice enjoyed immediate mainstream exposure, courtesy of his extensive career as an Internet-backyard-brawler.
His exploits eventually landed him in the now-defunct mixed martial arts promotion EliteXC. In his final appearance with the promotion, soon after cinching a TKO victory over PRIDE veteran James Thompson, Slice was viciously knocked out by UFC vet Seth Petruzelli.
Though Slice would eventually make his way inside the Octagon, his unbeatable facade quickly wore off as he suffered an additional loss to Matt Mitrione.
The Floridian has since ventured into the world of boxing, leaving behind his MMA ambitions, at least for the time being. Here, we will take a look at Slice and a number of other fighters who simply failed to live up to those high expectations.
