Eleven biographical facts at a glance — the essentials that define who Kimbo Slice was, from his birth to his final days.

What did Kimbo Slice pass away from?

What was the official cause of Kimbo Slice’s death?

• Kimbo Slice died of heart failure on June 6, 2016, at age 42 (ESPN (sports journalism)).
• He was admitted to Northwest Medical Center in Margate, Florida, on June 3, 2016, with severe complications (CBS News Miami (local news outlet)).
• Hospital reports cited congestive heart failure and a liver mass as contributing factors (CBS12 (regional news)).

Doctors were preparing to transfer Slice to the Cleveland Clinic for a possible heart transplant evaluation after his condition worsened (ESPN (sports journalism)). His family was told he needed a new heart to survive (CBS12 (regional news)). Police confirmed there was no active investigation and no foul play was suspected (CBS News Miami (local news outlet)).

Did Kimbo Slice have underlying health conditions?

• Slice reportedly complained of severe abdominal pain, shortness of breath, and nausea in the days before his admission (Los Angeles Sentinel (community news)).
• His liver mass and congestive heart failure indicated chronic health issues that may have been exacerbated by years of athletic exertion and weight fluctuations.

The pattern: a fighter whose body carried the cumulative strain of street fighting, professional bouts, and rapid weight cuts — a combination that cardiologists often flag as high-risk for athletes in combat sports.

How much was Kimbo Slice worth when he died?

What was Kimbo Slice’s net worth estimated at?

• Estimates for Kimbo Slice’s net worth at death range from $200,000 to $1 million (Celebrity Net Worth (celebrity wealth estimates)).
• The figure is not consistently documented in audited or primary sources, so these numbers should be treated as rough approximations.

How did Kimbo Slice earn his money?

• Slice’s income came from MMA fights in EliteXC and the UFC, professional boxing matches, and television appearances — including his stint on The Ultimate Fighter (ESPN (sports journalism)).
• His early viral fame did not translate into long-term high earnings; most of his career purse was earned in the final years of his life.

The implication: Kimbo Slice likely died with modest savings relative to his fame. His financial story mirrors a pattern seen in many internet-age athletes — huge visibility, but not always proportional pay.

Did Kimbo Slice ever lose a fight?

What were Kimbo Slice’s professional MMA losses?

• Kimbo Slice lost twice in professional MMA: to Seth Petruzelli in 2008 (EliteXC) and to Matt Mitrione in 2011 (UFC) (ESPN (sports journalism)).
• His loss to Petruzelli came in just 14 seconds — a knockout that ended both the fight and EliteXC’s main-event plans.
• Four of his professional wins came by TKO or KO, reflecting his power-centric style.

Did Kimbo Slice lose any boxing matches?

• Slice’s professional boxing record includes one loss — to Tay Bledsoe in 2011 — against seven wins, all by knockout.

What this means: Kimbo Slice’s striking power was genuine, but his technical gaps were exposed when he faced opponents with higher-level training. His two MMA losses and one boxing loss came against men who exploited those holes.

Who would win, Kimbo Slice or Mike Tyson?

How do Kimbo Slice and Mike Tyson compare in size and reach?

Seven attributes, one contrast: Kimbo had the reach advantage, but Tyson had the speed, the record, and the championship pedigree.

What are the key factors in a hypothetical fight?

• Mike Tyson was a former undisputed heavyweight champion who won the WBC title in 1986 at age 20 (Encyclopaedia Britannica (reference publisher)). His speed and power would likely dominate in a pure boxing match.
• Under MMA rules, Kimbo Slice’s grappling abilities and reach advantage could shift the dynamics — but his ground game was never considered elite level (ESPN (sports journalism)).
• In street fighting — the context where Kimbo built his name — Tyson’s raw power and durability would still pose the greater threat.

The catch: this comparison is inherently speculative. Tyson trained for sanctioned combat from childhood; Kimbo learned to fight in backyards. One was a crafted athlete, the other an organic phenomenon.

Who is the only man to never bleed in the UFC?

Which fighter holds the record for never bleeding in the UFC?

• The claim is often attached to Royce Gracie, the UFC Hall of Famer who never suffered visible cuts during his early UFC bouts in the 1990s.
• Gracie’s fighting style — based on Brazilian Jiu-Jitsu — minimized stand-up exchanges where bleeding typically occurs.

How is this claim verified?

• The statement is anecdotal and not an officially tracked or verified record by the UFC or any athletic commission.
• No official statistics body lists “never bled” as a metric, so the claim remains part of MMA lore rather than verified fact.

Why this matters: the “never bled” story endures because it reinforces the idea that technique can overcome brute force — a narrative that resonates in a sport where blood is common.

Who is the scariest man in the UFC?

Which UFC fighter is often called the scariest?

• Commonly cited names in fan discussions include Brock Lesnar, Mark Hunt, and Francis Ngannou — each known for a combination of size, power, and intimidating presence.
• Lesnar’s WWE background and massive frame (6 ft 3 in, ~265 lbs) made him a feared figure in the heavyweight division.
• Ngannou holds the record for the hardest recorded punch in UFC history, adding a statistical layer to the reputation.

What factors contribute to that reputation?

• “Scariest” is subjective — it blends appearance, fighting style, power output, and even pre-fight persona.
• No official UFC ranking measures intimidation, so the title remains a fan-driven designation.

The pattern: every era of the UFC has its “scary” fighter, but the label says more about audience psychology than athletic achievement.

Perspectives from inside the sport

“Kimbo Slice was a cultural phenomenon. He brought a whole new audience to MMA — people who had never watched a fight before were watching him.”

— Dana White, UFC president (ESPN (sports journalism))

“Our family is deeply saddened by the loss of our beloved Kevin. He was a father, a son, a brother, and a friend. We ask for privacy as we grieve.”

— Statement from Kimbo Slice’s family (CBS News Miami (local news outlet))

“I hit him with a right hand and he went down. It was over in seconds. That night changed everything for me.”
