KOTS vs Top Dog FC: Europe's Two Underground Fight Empires Compared
Europe's underground fighting scene is dominated by two organizations that have built massive audiences and global reputations from opposite ends of the continent. King of the Streets (KOTS), operating out of Sweden with tentacles across Western Europe, represents the no-rules extreme of unsanctioned fighting. Top Dog Fighting Championship, based in Moscow and commanding arena-level production, has built the biggest bare knuckle promotion in Eastern Europe. Together, they define what underground fighting looks like on the European stage -- but their approaches could not be more different.
Both organizations feature bare knuckle striking. Both operate outside the traditional athletic commission framework. Both have YouTube audiences numbering in the millions. And yet, in rules, production, fighter treatment, and organizational ambition, KOTS and Top Dog FC represent fundamentally different visions of what fighting outside the system should look like.
Origins and Philosophy
King of the Streets (KOTS)
KOTS was founded in 2013 in Gothenburg, Sweden by the anonymous Hype Crew -- a collective described as hooligans, organized criminals, and seasoned street fighters. The philosophy is pure: remove every possible safety net and find out who the toughest person is under the most hostile conditions available. No rules, no rounds, no gloves, no soft surfaces. KOTS fights happen on bare concrete, and that is not incidental -- it is the defining feature.
The founders' anonymity is both practical and ideological. KOTS operates illegally in most European jurisdictions, and the leadership has remained hidden behind the brand since its inception. The organization has deep connections to European football hooligan culture, with prominent hooligans from across the continent competing in bouts. Reporting has linked some participants to far-right extremist and neo-Nazi circles, adding a layer of political controversy that KOTS has never meaningfully addressed.
KOTS birthed the broader "No Rules" fighting movement in 2018, spawning unaffiliated copycat clubs across Germany, England, Ireland, France, Denmark, and Poland.
Top Dog FC
Top Dog Fighting Championship was founded around 2019 in Moscow and rapidly established itself as the first and largest bare knuckle promotion in Eastern Europe. Unlike KOTS, Top Dog FC has ambitions that look more like a professional sports promotion than an underground fight club. Major events are held at CSKA Arena in Moscow, with proper production, lighting, camera setups, and a streaming platform at topdogfc.tv.
Top Dog FC positions itself as the Eastern European answer to organizations like BKFC, but with a distinct Russian combat culture flavor. The fighters wear jeans or sweatpants instead of traditional fight shorts, the ring is a circle of hay bales instead of ropes or a cage, and the atmosphere blends professionalism with deliberate rawness. The organization operates with a level of openness and branding sophistication that sets it apart from the secrecy-driven model of KOTS.
Rules and Format
| Aspect | KOTS | Top Dog FC |
|---|---|---|
| Rounds | None -- fights continue until stoppage | 5 rounds x 2 minutes (championship fights) |
| Time Limits | None | Timed rounds |
| Gloves | None | None (bare knuckle) |
| Fighting Surface | Bare concrete | Arena floor within hay bale circle |
| Ring/Cage | Open area on concrete | Circle of hay bales |
| Weight Classes | Loosely matched, no formal classes | 6 formal weight classes |
| Allowed Techniques | Strikes, grappling, submissions, headbutts, soccer kicks, eye gouging | Punching, clinch strikes, open palm strikes, shoulder strikes |
| Ground Fighting | Allowed | Limited (primarily stand-up) |
| Win Conditions | KO, TKO, submission, verbal submission | KO, TKO, decision (no draws in championship fights) |
| Attire | Anything | Jeans/sweatpants, sneakers |
The rules gap between these two organizations is enormous. KOTS is functionally no-rules fighting on the most dangerous surface possible. Top Dog FC is a structured bare knuckle boxing promotion with weight classes, timed rounds, and clear technical boundaries.
KOTS allows ground fighting, headbutts, soccer kicks, and even eye gouging (though fighters who win by eye gouge forfeit their prize money since December 2022). Top Dog FC keeps the action standing and punching-focused, with clinch strikes and shoulder strikes adding variety but without the ground-fighting chaos that defines KOTS.
The hay bale circle in Top Dog FC is visually distinctive but also functional -- it creates a defined fighting area while maintaining the aesthetic rawness that separates underground fighting from the sanitized cage or ring.
Production and Presentation
| Production Element | KOTS | Top Dog FC |
|---|---|---|
| Venue | Secret locations, undisclosed until shortly before events | CSKA Arena, Moscow (public venue) |
| Camera Work | Multiple angles, high production for underground | Professional multi-camera production |
| Streaming | YouTube, PPV, Bitchute | YouTube, topdogfc.tv (own platform) |
| Branding | Anonymous, underground aesthetic | Professional sports branding |
| Commentary | Varies | Professional commentary |
| Social Media | Instagram (671K+), YouTube (1M+) | Instagram (@topdogfights), YouTube |
Top Dog FC operates at a production level that is closer to a professional combat sports promotion than an underground fight club. The CSKA Arena events feature proper lighting rigs, walkout music, multiple camera crews, and broadcasting infrastructure comparable to mid-tier professional promotions. The organization's own streaming platform at topdogfc.tv represents a serious investment in independent content distribution.
KOTS has notably higher production quality than most underground operations, with multiple camera angles, graphics packages, and post-production editing. However, the deliberately secretive venue operations -- locations shared only shortly before events via Telegram -- create an atmosphere that is fundamentally different from Top Dog FC's arena shows. KOTS events feel like you are watching something you should not be seeing. Top Dog FC events feel like you are watching a professional show with an underground edge.
Fighter Ecosystem
KOTS Fighters
KOTS draws from Europe's football hooligan scene, street fighting culture, and martial arts communities. Fighters often compete under aliases, and personal information is kept intentionally vague. The hooligan pipeline is a significant recruitment channel, with fighters from firms across the continent entering KOTS bouts. The political connections to far-right movements mean the fighter pool carries ideological baggage that the organization has never distanced itself from.
Fighter safety at KOTS is minimal. The concrete surface means every takedown and knockdown carries the risk of skull fractures and traumatic brain injury. No medical staff has been publicly reported at events.
Top Dog FC Fighters
Top Dog FC has built a genuine roster with recognizable stars and competitive hierarchies. Notable fighters include:
- Naim "Samurai" Davudov -- ranked #6 P4P on the BK Nations list, making him one of the highest-ranked bare knuckle fighters globally
- Alexander "Drago" Shapovalov -- a notable heavyweight competitor
- Gia "The Ogre" Torchinava -- known for intense, crowd-pleasing bouts
- Alex Terrible -- the vocalist of metal band Slaughter to Prevail, who brought celebrity crossover attention to the promotion
The inclusion of ranked fighters on international bare knuckle lists demonstrates that Top Dog FC operates at a competitive level that commands respect from the broader bare knuckle community. This is not amateur hour -- these are trained, ranked fighters competing in a structured promotion.
Safety and Medical Provisions
| Safety Factor | KOTS | Top Dog FC |
|---|---|---|
| Medical Staff | Not reported | Available at arena events |
| Fighting Surface | Concrete | Arena floor (softer than concrete) |
| Protective Gear | None | None (bare knuckle) |
| Weight Matching | Loose, informal | 6 formal weight classes |
| Referee | Present for stoppages | Active refereeing |
| Event Security | Secret locations, limited oversight | Arena security, professional setup |
The safety differential is significant. Top Dog FC's formal weight classes prevent the kind of size mismatches that can occur at KOTS, where fighters are loosely matched and significant weight disparities are not uncommon. The arena environment at Top Dog FC provides access to medical facilities, security infrastructure, and emergency services that secret-location KOTS events cannot match.
The fighting surface alone represents a massive safety gap. Getting knocked down on an arena floor with hay bales as boundaries is dangerous. Getting knocked down on bare concrete with no boundaries is potentially fatal.
Legal Status and Controversy
KOTS
KOTS operates illegally in virtually every jurisdiction where it holds events. The anonymous leadership, secret locations, and Telegram-based communication all exist because the events violate combat sports regulations throughout Europe. The connections to football hooliganism and far-right extremism have drawn media scrutiny and law enforcement attention, though the organization has continued operating despite these pressures.
Top Dog FC
Top Dog FC occupies an ambiguous legal space in Russia. The organization operates with a degree of openness -- using public arenas, building a branded streaming platform, maintaining open social media profiles -- that suggests it exists with at least tacit tolerance from Russian authorities. Russia's regulatory environment for combat sports is different from Western Europe's, and the promotion appears to have found sufficient legal or institutional cover to operate at scale.

The Verdict
KOTS and Top Dog FC represent two distinct evolutionary paths for European underground fighting.
KOTS is the purist's underground fight club. It exists to answer the rawest possible question -- who wins when every rule is stripped away and the floor is concrete? The anonymity, the secrecy, the hooligan culture, and the no-rules format create an experience that is genuinely dangerous and deliberately transgressive. KOTS does not want to be legitimate. It wants to be extreme.
Top Dog FC is the underground with professional ambitions. It takes the rawness of bare knuckle fighting, wraps it in arena-level production, structures it with weight classes and rounds, and presents it as a viable combat sports product. Fighters are ranked internationally. Events are held in major venues. The organization has built its own streaming platform. Top Dog FC is not trying to be an underground fight club forever -- it is building something that could eventually stand alongside sanctioned bare knuckle promotions.
For viewers who want to see the most extreme, unregulated fighting available, KOTS delivers that experience at a level no other European organization matches. For viewers who want high-quality bare knuckle action with structure and production value, Top Dog FC is the Eastern European standard-bearer.
They share a continent but occupy different worlds.
