Dada 5000 (Dhafir Harris): From Kimbo's Shadow to BYB Founder
The story of Dada 5000 is one of the most harrowing, dramatic, and consequential narratives in the history of underground fighting. Born Dhafir Harris in the same Perrine neighborhood of Miami that produced the legendary Kimbo Slice, Dada 5000 walked a parallel path to his more famous rival -- from backyard brawls to professional combat -- but his journey was marked by deeper valleys, including a near-death experience inside a Bellator cage that would have ended most men's involvement in the sport entirely. Instead, Harris emerged from the other side of cardiac arrest and kidney failure to found BYB Extreme Fighting Series, transforming himself from fighter to promoter and creating a platform that would eventually merge with BKB to form one of the largest bare knuckle organizations outside of BKFC.

Overview
Dhafir "Dada 5000" Harris occupies a unique position in combat sports history. He is not remembered primarily for his wins or his technical skill, though he possessed enough of both to compete at the professional level. He is remembered for the sheer force of his narrative -- a story that encompasses one of the fiercest rivalries in backyard fighting, one of the most terrifying medical emergencies in MMA history, and one of the most remarkable second acts in the sport.
Dada 5000 grew up in Perrine, a rough neighborhood in southern Miami-Dade County that served as the cradle of backyard fighting culture in America. It was here that Kevin Ferguson, who would become Kimbo Slice, rose to fame through viral street fight videos that changed the combat sports landscape forever. And it was here that Harris, operating in Kimbo's considerable shadow, built his own reputation as a fighter and organizer who could draw crowds and generate excitement in the lawless arena of backyard combat.
The two men's paths were intertwined from the beginning. Harris worked as Kimbo's bodyguard before their relationship fractured over business disputes and personal conflicts. What followed was a rivalry that simmered for years, playing out in the media and on social platforms before finally culminating in a professional fight at Bellator 149 that nearly killed Dada 5000 and ended with both men's results being overturned.
What makes Harris's story extraordinary is what came after. Rather than retreating from combat sports after his near-death experience, he channeled his energy into building BYB Extreme Fighting Series, a promotion that brought the backyard fighting culture he knew so intimately into a more organized, structured framework. That promotion's eventual merger with BKB in 2024 created one of the most significant bare knuckle organizations in the world, cementing Harris's legacy not just as a fighter but as a builder of the sport.
Background
The Perrine Streets
Perrine, Florida, is not a neighborhood that appears in tourism brochures. Located in the southern reaches of Miami-Dade County, it has long been one of the roughest areas in greater Miami -- a community where poverty, violence, and limited economic opportunity create conditions that push young men toward the streets. It is also, not coincidentally, the birthplace of American backyard fighting culture.
Dhafir Harris grew up in this environment, and like many young men in Perrine, he gravitated toward fighting as both a survival skill and a source of identity. The backyard fight scene in Miami during the early 2000s was not an organized sport -- it was a raw, unregulated expression of the community's competitive spirit, with fighters squaring off in backyards, parking lots, and vacant lots for bragging rights, cash, and the respect of their peers.
It was in this world that Harris met Kevin Ferguson. The two men shared a neighborhood, a physical presence (both were large, physically imposing men), and a willingness to fight. Harris worked as Kimbo's bodyguard during the period when Ferguson was building his reputation through viral fight videos that would eventually make him the most famous street fighter in the world.
The Kimbo Rift
The relationship between Dada 5000 and Kimbo Slice is one of the most compelling rivalries in combat sports history, not because of what happened in the ring but because of the personal dynamics that fueled it.
According to Harris, the rift began when Kimbo's management team deliberately buried Dada's debut fight video, preventing it from gaining the viral traction that had launched Kimbo's career. Whether this account is entirely accurate or colored by the bitterness of a fractured relationship, the result was clear: Harris felt that he had been denied the opportunity to build his own fighting brand, and the betrayal fueled a grudge that would simmer for years.
In the absence of viral support from Kimbo's management apparatus, Dada 5000 began organizing his own backyard fighting events in the Perrine area. These events, later documented in the 2015 film "Dawg Fight" (directed by Billy Corben, who also directed the acclaimed documentary "Cocaine Cowboys"), showcased the raw, desperate combat that characterized Miami's underground fighting scene. The documentary portrayed a world where men fought for small purses and neighborhood glory, often in conditions that would horrify athletic commissions but that accurately reflected the reality of life in Perrine.
Career and Notable Fights
The Backyard Years
Dada 5000's reputation was built in the backyards and vacant lots of Miami-Dade County. As both a fighter and an organizer, Harris became a central figure in the local underground fight scene, known for his physical size, his willingness to engage, and his ability to draw crowds to his events. The "Dawg Fight" documentary captured this period of his career, presenting Harris as both a product of and a participant in a fighting culture that was equal parts desperation and defiance.
Bellator 149: The Fight That Nearly Killed Him
On February 19, 2016, the rivalry between Dada 5000 and Kimbo Slice finally culminated in a professional fight at Bellator 149, held at the Toyota Center in Houston, Texas. The bout was one of the most anticipated and most criticized fights in Bellator history -- anticipated because of the years of personal animosity between the two men, and criticized because neither fighter possessed the technical skill set that would normally warrant a spot on a major MMA card.
The fight itself was, by any technical measure, a disaster. Both men gassed quickly, throwing slow, labored punches that reflected their limited training and declining physical condition. Kimbo ultimately won by TKO in the third round, but the result was secondary to what happened after the fight.
In the minutes following the bout, Dada 5000 collapsed backstage. He was rushed to the hospital, where he was diagnosed with cardiac arrest and kidney failure. Harris was placed in a medically induced coma, and for a period, his survival was genuinely uncertain. The medical emergency cast a harsh spotlight on the risks of combat sports and raised serious questions about the matchmaking and medical protocols that had allowed two men in questionable physical condition to compete in a professional MMA bout.
The fight's aftermath took another twist when Kimbo Slice tested positive for a banned substance (elevated testosterone), and the result was overturned to a no-contest. The entire episode -- the years of rivalry, the anticlimactic fight, the near-death experience, and the positive drug test -- became one of the most surreal chapters in MMA history.
Tragically, Kimbo Slice passed away on June 6, 2016, from congestive heart failure at the age of 42, just four months after the fight. The death of his rival added another layer of gravity to an already heavy story and deprived the world of any possibility of resolution between the two men.
The BYB Chapter
Rather than being destroyed by the Bellator experience, Dhafir Harris used it as motivation to build something lasting. In April 2019, he founded BYB Extreme Fighting Series in Miami, creating a promotion that brought the backyard fighting culture he knew intimately into a more organized framework with bare knuckle as its centerpiece.
BYB represented Harris's vision for what backyard fighting could become -- a legitimate platform that honored the raw, unfiltered spirit of the streets while providing fighters with a structured environment and medical oversight. The promotion grew steadily, eventually catching the attention of BKB (Bare Knuckle Boxing), a UK-based promotion. In May 2024, BYB was acquired by BKB, and the merged entity was rebranded as BKB Bare Knuckle Boxing, creating one of the largest bare knuckle organizations outside of BKFC.
Fighting Style
Dada 5000's fighting style reflected his background: raw, unrefined, and built on physicality rather than technical sophistication.
Size and Power
At 6'2" and approximately 265 pounds, Harris was an imposing physical presence. His punching power, while not always delivered with technical precision, was significant simply by virtue of the mass behind it. In the backyard context, where fights were often decided by who could hit harder rather than who could box better, Dada's size was his primary weapon.
Toughness
The defining attribute of Harris's fighting career was his willingness to endure. A man who survived cardiac arrest and kidney failure is, by definition, tough in ways that transcend combat sports. Harris's ability to absorb punishment and keep competing -- whether in the backyards of Perrine or on the Bellator stage -- reflected a resilience that was as much psychological as physical.
Limitations
It would be dishonest to portray Dada 5000 as a skilled fighter in the traditional sense. His cardio was limited, his technique was rudimentary, and his professional MMA record of 2-1 (1 NC) does not suggest elite-level ability. But Harris's significance in the sport was never about his skill as a fighter -- it was about his role as a cultural figure and a builder of platforms for other fighters.
Legacy
Dada 5000's legacy is multifaceted and resists simple categorization. As a fighter, he was limited but significant -- a man whose rivalry with Kimbo Slice became one of the defining narratives of the backyard fighting era and whose near-death experience at Bellator 149 remains one of the most sobering moments in MMA history.
As a promoter and builder, Harris's contribution to the sport is far more substantial. BYB Extreme gave a generation of fighters from Miami's underground scene a platform to compete in a more structured environment, and the promotion's merger with BKB created an organization with genuine scale and ambition in the bare knuckle space.
The "Dawg Fight" documentary ensures that Harris's story -- and the story of the Perrine fighting community he helped put on the map -- will continue to reach new audiences for years to come. The film captures a world that is simultaneously horrifying and compelling, and Harris is its most complex character: a man who was both a product of and a response to the violence that surrounded him.
Perhaps most importantly, Dada 5000's story is one of survival and reinvention. He survived the streets of Perrine. He survived the fallout of his rivalry with Kimbo Slice. He survived cardiac arrest and kidney failure inside a Bellator cage. And he emerged from all of it not broken but transformed, channeling his experience into building something that outlasts his career as a fighter.
In the lineage of underground fighting -- from the backyards of Miami to the sanctioned rings of BKB -- Dhafir "Dada 5000" Harris stands as one of the most important figures in the sport's evolution.
