Most Watched Underground Fights on YouTube by View Count
YouTube is the lifeblood of underground fighting. While mainstream combat sports rely on pay-per-view buys and cable television ratings, the underground scene has always lived and died by view counts, subscriber numbers, and the algorithmic favor of the world's largest video platform. The organizations that dominate underground fighting today -- Streetbeefs, Strelka, Top Dog FC, KOTS -- built their audiences one uploaded fight at a time.
Some of those fights went viral. A few went genuinely massive -- crossing tens of millions of views, spreading beyond combat sports audiences into mainstream internet culture, and becoming the videos that introduced millions of people to the world of underground fighting. This ranking catalogs the most-watched underground fights on YouTube, organized by view count tiers, with context on why each fight captured the internet's attention.
Tier 1: The 20-Million-Plus Club
Andrei Petrantsov's Walk-On Knockout -- Strelka (24M+ views)
Organization: Strelka | Fighter: Andrei Petrantsov
The single most-watched moment in underground fighting history. A truck driver from Bryansk, Russia, who had no fighting background, no gym affiliation, and no intention of competing, walked past a Strelka event, volunteered to fill a spot, and delivered a single-punch knockout so sudden and devastating that it became a global viral phenomenon. Over 24 million views on the primary YouTube upload alone, with countless additional views across ripped clips on TikTok, Instagram, Facebook, and combat sports forums worldwide.
Why it went viral: The narrative is perfect. An ordinary man does something extraordinary. No setup, no training montage, no promotional hype. Just a truck driver, a sand ring, and a punch that changed his life. The clip captures the fundamental promise of Strelka -- that anyone, from any background, can step into the ring and produce something miraculous -- in its most concentrated form.
Strelka Compilation Fights (20M+ views, various)
Organization: Strelka
Strelka's YouTube channel has accumulated over 1.5 billion total views, and several individual compilation videos -- featuring the best knockouts, most dramatic finishes, and most unexpected outcomes from across the organization's history -- have crossed the 20-million-view threshold. These compilations function as gateway content, introducing new audiences to the Strelka brand and driving subscriptions to the channel. The compilations' success reflects a content strategy that Strelka perfected early: package the best moments from a high-volume content operation into digestible highlight reels that the YouTube algorithm rewards.
Tier 2: The 10-Million-View Club
Streetbeefs: ATrain vs. Dusty Shaw (10M+ views estimated)
Organization: Streetbeefs | Fighters: ATrain (Alan Stephenson) vs. Dusty Shaw
One of the most talked-about bouts in Streetbeefs history, this fight pitted two fighters with legitimate professional MMA experience against each other in the Virginia yard. The matchup drew attention precisely because it was so rare -- two credentialed professionals settling a personal dispute through Streetbeefs rather than in a sanctioned cage. ATrain's eventual finishing flurry against the makeshift wall produced one of the most replayed sequences in Streetbeefs history and prompted widespread discussion about the caliber of fighters appearing on the platform.
Why it went viral: The professional credentials of both fighters elevated this beyond a typical backyard brawl. Combat sports media picked up the story, driving viewers who would never normally watch Streetbeefs to seek out the clip.
Top Dog FC: Drago vs. The Ogre (10M+ views estimated across uploads)
Organization: Top Dog FC | Fighters: Alexander "Drago" Shapovalov vs. Gia "The Ogre" Torchinava
The most famous fight in Top Dog FC history. A genuine bloodbath between two heavyweights in the hay bale ring that pushed both men to their physical limits. The fight became the signature content piece for Top Dog's international expansion -- the clip that Western audiences shared when explaining what Russian bare knuckle fighting looked like.
Why it went viral: Pure violence. Two large men with heavy hands standing in front of each other and throwing until someone drops, surrounded by hay bales, wearing jeans. The visual is so distinctive and the action so relentless that the clip transcends language barriers. English-speaking audiences who could not understand the Russian commentary shared it based on the imagery alone.
Streetbeefs: Shinigami's "Kick Heard Around the World" (10M+ views estimated)
Organization: Streetbeefs West Coast | Fighter: Shinigami (Danny Uribe)
Shinigami's viral knockout at the first-ever Streetbeefs West Coast event -- a spinning technique that landed flush and ended the fight instantly -- became one of the most shared moments in Streetbeefs history. The clip spread across YouTube, TikTok, and MMA forums, turning a goth karate devotee with an anime ring name into a genuine star.
Why it went viral: The underdog narrative was irresistible. A heavyset goth guy in anime gear walks into a backyard fighting event and knocks someone out with a spinning kick. The contrast between appearance and performance, between expectation and reality, is exactly the kind of moment that social media algorithms reward.
Tier 3: The 5-Million-View Club
BKFC: Mike Perry vs. Jeremy Stephens (5M+ views estimated across platforms)
Organization: BKFC | Fighters: Mike Perry vs. Jeremy Stephens
Mike Perry's demolition of Jeremy Stephens at BKFC 82 in October 2025 -- six knockdowns including three in the fifth round, forcing a TKO with 25 seconds remaining -- was the most emphatic performance of 2025 in any bare knuckle organization. Perry was crowned the inaugural King of Violence after the bout, and the highlight reel circulated across every combat sports platform.
Why it went viral: Perry's existing UFC fanbase amplified the reach beyond bare knuckle audiences. The visual of six knockdowns in a single fight, with both fighters competing without gloves, produced shareable highlight-reel content that even casual combat sports fans found compelling.
KOTS: Henriksen's Undefeated Run (5M+ views estimated across multiple uploads)
Organization: KOTS | Fighter: Simon "The Savage" Henriksen
Simon Henriksen's fights in KOTS have collectively generated millions of views. The Danish fighter's undefeated record in the no-rules format, combined with the inherently shareable nature of KOTS content -- fights on concrete, no gloves, no rules -- has made his bouts among the most viewed in the organization's history. His fight against M16 in particular generated significant viewership as a marquee matchup between two of the organization's best.
Why it went viral: KOTS content is inherently viral because of its extreme nature. Henriksen's dominance within that format adds a narrative layer that drives repeat viewership and sharing.
Streetbeefs: ATrain vs. Italian Tyson (5M+ views estimated)
Organization: Streetbeefs | Fighters: ATrain vs. Italian Tyson
The boxing match that showcased the gap between professional technique and backyard aggression. ATrain's systematic dismantling of Italian Tyson's aggressive style -- neutralizing the looping hooks with head movement, then attacking the body to break down the guard -- became a tutorial on the difference between trained and untrained fighters. The fight was shared widely in martial arts communities as a demonstration of ring intelligence.
Why it went viral: Educational value combined with entertainment. Martial arts channels and combat sports forums used the fight as case study material, driving views from audiences interested in technique analysis as much as action.
The Scrapyard: iShowSpeed Crossover Event (5M+ views estimated)
Organization: The Scrapyard
The Scrapyard's collaboration with iShowSpeed -- one of YouTube's biggest creators -- introduced backyard fighting to an audience of millions who had never encountered the format. The crossover event generated massive viewership both on iShowSpeed's channel and The Scrapyard's platforms, demonstrating the power of influencer collaboration in driving fight content to mainstream audiences.
Why it went viral: iShowSpeed's massive subscriber base (tens of millions) provided instant distribution to an audience outside the combat sports bubble. The novelty of watching a mainstream YouTuber interact with grassroots backyard fighting created shareability that pure fight content alone could not achieve.
Tier 4: The 1-to-5-Million-View Club
Strelka: David vs. Goliath Size Mismatches (1-5M views each, multiple)
Strelka's open-entry format regularly produces dramatic size mismatches. Clips of undersized fighters defeating significantly larger opponents have collectively generated tens of millions of views across dozens of uploads. The David vs. Goliath narrative is universally appealing and translates across languages and cultures.
Top Dog FC: Alex Terrible's Fighting Debut (1-5M views estimated)
Alex Terrible's transition from Slaughter to Prevail frontman to bare knuckle fighter generated significant views driven by his existing fanbase in the metal community. His fighting debut at RCC HARD 12 in January 2025 was appointment viewing for both metal fans and combat sports audiences.
Streetbeefs: Delvin Hamlett Highlight Reels (1-5M views, various)
Delvin "Kuntry Hoodlum" Hamlett's knockout power produced numerous highlight clips that circulated across YouTube and social media. His Power Slap knockout of Jonathan Correa -- broadcast on TBS to a national audience -- drove additional retrospective viewership of his Streetbeefs fights.
BKFC: Christine Ferea Queen of Violence Coronation (1-5M views estimated)
Christine Ferea stopping Jessica Borga via fourth-round TKO at BKFC 82, followed by Conor McGregor crowning her as Queen of Violence, produced shareable content that transcended the bare knuckle niche. McGregor's involvement amplified the reach dramatically.
Top Dog FC: Regbist vs. Alex Terrible (1-5M views estimated)
Danil "Regbist" Aleyev defeating Alex Terrible at Top Dog 37 -- the promotion founder beating the metal superstar on his own card -- generated views from both the Top Dog fanbase and Alex Terrible's substantial social media following.
KOTS: Concrete Knockout Compilations (1-5M views, various)
KOTS knockout compilations -- featuring the most dramatic finishes on concrete from across the organization's history -- are among the most shared no-rules fighting content on YouTube. The extreme visual nature of knockouts on an unforgiving surface drives clicks and shares.
The YouTube Economy of Underground Fighting
The view counts above tell a story about how underground fighting organizations build their audiences and sustain their operations. Unlike BKFC, which generates revenue primarily through PPV and gate receipts, most underground organizations depend on YouTube ad revenue, social media sponsorships, and merchandise sales driven by video content.
This creates a content incentive structure that rewards:
- Viral moments -- Single knockouts or dramatic finishes that spread beyond the core audience
- Compilation content -- Best-of packages that the YouTube algorithm promotes to new viewers
- Celebrity crossovers -- Collaborations with mainstream creators that open new audience pipelines
- Narrative-driven content -- Underdog stories, rivalries, and dramatic character arcs that drive engagement
The organizations that understand this economy -- Streetbeefs, Strelka, The Scrapyard, and Top Dog FC -- have built audience numbers that dwarf many professional promotions. Streetbeefs' 4.2 million subscribers and 1.3 billion views. Strelka's 2.45 million subscribers and 1.5 billion views. The Scrapyard's 540 million views. These numbers represent genuine media properties built on the foundation of uploaded fight content.
The most-watched fights on this list are the tentpole moments that drove the growth of those properties. Each viral clip brought new subscribers, each new subscriber watched more content, and the flywheel of audience growth powered organizations that operate with a fraction of the budget of their mainstream counterparts. In the underground fighting world, a single punch from a truck driver in Bryansk can be worth more than a million-dollar marketing campaign. That is the YouTube economy of underground fighting, and it shows no signs of slowing down.
