History:

Kimbo Slice was a Miami, Florida-based underground street fighter. The underground fight videos swept across the web making him an overnight sensation. The brutal knockouts, tough appearance of Kimbo, and catchy phrases increased his popularity.

He started an MMA career after the popularity of the sport rose due to the success of the UFC. He started fighting for the now defunct EliteXC promotion. Kimbo became one of the most seen fighters when EliteXC became the first fight promotion to run on national TV on CBS. His fight on their first event was seen by over 5 million people. While he was undefeated, Kimbo was seen by in the fight business as not a real fighter, but, still just a street fighter. In his next fight he was exposed after being knocked out in under a minute by a fill in who was also a lighter weight opponent, Seth Petrazelli. After the loss, Kimbo did not fight again largely due to EliteXC closing.
