2. Dada 5000
Dhafir Harris, aka Dada 5000, was a street fighter until he transitioned to sanctioned bouts in 2010.
Technically, Dada 5000 has retired unbeaten in MMA. His one and only loss to Kimbo Slice was overturned after Kimbo tested positive for a few “extra vitamins” as he would later refer to nandrolone as. His career record is official 2W-0L-1NC.
The former street fighter was also featured in the 2015 documentary “Dawg Fight”. The film focussed on street fights across America. Dada 5000 would decide to fight again for the first time in years following the release of the documentary.
Harris fought professionally twice before his bout with Kimbo. He knocked out his opponents in the first round each time. By the time of his infamous Bellator 149 bout however, 5 years had passed. Harris famously gassed out during his much-maligned bout with Kimbo, and would go into cardiac arrest later that night. Medical professionals wouldn’t let him leave the hospital for two weeks after the fight.
