Meet “Dada 5000,” a muscular Dade County brawler with a quick wit, a big heart, and an entrepreneurial zeal. After working as a bodyguard for mixed martial arts fighter Kimbo Slice, Dada grew disenchanted with the gig. We meet him as he turns his energy to holding homegrown (and illegal) MMA-style fights in his mother’s yard that bring out the whole neighborhood.
