Underground Fighting P4P Rankings: The Best Fighters Across All Organizations
Ranking fighters across different underground fighting organizations is an inherently subjective exercise. The rulesets vary wildly -- from sanctioned bare knuckle boxing under state athletic commissions to no-rules brawls in European basements. The talent pools overlap in some places and exist in completely different universes in others. A BKFC champion operates under medical supervision, drug testing, and professional training camps. A King of the Streets fighter might show up having trained in a parking garage.
But that is precisely what makes cross-organizational rankings worthwhile. The underground fighting scene in 2026 is broader and deeper than it has ever been, spanning multiple continents, formats, and levels of legitimacy. Someone has to attempt to sort it all out.
These rankings consider win-loss record, quality of opposition, dominance within their organization, crossover appeal, and the difficulty of the format they compete in. Fighters are ranked as of March 2026.
Overall Pound-for-Pound Top 15
This is the master list. Every fighter from every underground and bare knuckle organization is eligible. The only requirement is that their primary competition takes place outside the UFC, PFL, ONE, and other mainstream MMA promotions.
1. Austin Trout -- BKFC Lightweight Champion
Record: 5-0 (BKFC) | Previous: Former WBA Super Welterweight World Champion (boxing)
Austin Trout sits at the top of these rankings because he represents something rare: a genuine world-class combat sports athlete competing in the bare knuckle space. The former WBA world champion brought elite-level boxing fundamentals to BKFC and has been virtually untouchable. His 2025 title defense against Carlos Trinidad-Snake in Dubai went to a split decision, proving he can be pushed, but his TKO of Luis Palomino at BKFC 85 in December 2025 showed he still possesses finishing power. Currently ranked #1 in BKFC's official pound-for-pound rankings and advancing to the lightweight tournament final against Franco Tenaglia in 2026, Trout is the most credentialed fighter competing in any underground or bare knuckle format.
2. Kai Stewart -- BKFC Featherweight Champion
Record: 8-0 (BKFC), 5-0 in championship fights
The Great Falls, Montana, native has been called the "new face of BKFC," and the numbers back it up. Stewart is a perfect 8-0 in the promotion with four successful title defenses, most recently a dominant unanimous decision over undefeated Tommy Strydom at BKFC 72 in Dubai (April 2025) where all three judges scored it 50-43. Stewart combines speed, precision, and ring intelligence in a way that makes him look like he belongs in a different sport than his opponents. At 26, he has years of prime competition ahead of him and the potential to become the greatest bare knuckle fighter of his generation.
3. Mike Perry -- BKFC "King of Violence"
Record: 6-0 (BKFC) | Previous: UFC veteran (14-8)
"Platinum" Mike Perry brought name recognition and genuine UFC-level striking to bare knuckle, and he has backed up the hype with a perfect 6-0 record. His 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 the year in any bare knuckle organization. Perry was crowned the inaugural "King of Violence" and sits at #5 in BKFC's official P4P rankings. He ranks higher on this list because his crossover credentials and finishing rate set him apart from fighters who have only competed in one format.
4. LT Nelson -- BKB
Record: Active BKB competitor
Nelson has established himself as one of the most consistent performers in BKB Bare Knuckle Boxing, earning the #2 spot on Bare Knuckle Nation's cross-organizational pound-for-pound list. His technical approach and ability to win fights without taking excessive damage set him apart in a sport that rewards toughness as much as skill. Nelson's success across multiple BKB events has made him a standard-bearer for the promotion as it expands under the VICE TV deal.
5. Naim "Samurai" Davudov -- Top Dog FC
Record: Multiple Top Dog victories
Davudov is the most technically accomplished fighter on the Top Dog FC roster and one of the few underground fighters who could plausibly compete at a high level in sanctioned professional boxing. Ranked #6 on Bare Knuckle Nation's global pound-for-pound list, the "Samurai" combines Russian combat sport fundamentals with a composed fight IQ that stands out in Top Dog's often chaotic environment. His fights are a showcase for what bare knuckle boxing looks like when practiced at an elite level.
6. David Mundell -- BKFC Champion
Record: Active BKFC champion
Mundell earned his championship in emphatic fashion, stopping Josh Dyer via first-round knockout at BKFC 84 Palm Desert in November 2025. The speed of that finish -- and the quality of the opponent -- elevated Mundell's standing significantly. He ranks #4 in BKFC's official rankings and has the kind of explosive power that makes him a threat to anyone in the bare knuckle world.
7. Gustavo Trujillo -- BKB
Trujillo has quietly built one of the most impressive resumes in the BKB promotion, earning a spot at #5 on Bare Knuckle Nation's cross-organizational list. His consistency and ability to win against diverse opponents make him a cornerstone of the BKB roster.
8. Alberto Blas -- BKFC
Blas has been one of BKFC's most reliable performers, combining volume striking with durability. His ranking at #6 on BKFC's internal list reflects a body of work that includes wins over ranked opponents and the kind of crowd-pleasing style that has made him a fan favorite.
9. Alessio Sakara -- BKFC Cruiserweight Champion
Previous: UFC veteran (17-13-1)
The 43-year-old Italian legend joined BKFC in mid-2025 and immediately made an impact, knocking out Erick Lozano in his debut at BKFC Fight Night Philly in July. He then won the cruiserweight championship by split decision over Chris Camozzi at BKFC 83 in October 2025. Sakara's UFC pedigree and ability to win a title in his first months in bare knuckle demonstrate the kind of crossover talent that elevates the entire sport.
10. Marko Martinjak -- BKB
Martinjak has been a consistent presence in BKB competition, earning a top-ten spot on the cross-organizational bare knuckle rankings. His technical proficiency and durability make him a difficult out for anyone in the promotion.
11. Bloodaxe -- KOTS
The most infamous fighter on the KOTS roster, Bloodaxe is an American bare knuckle boxer who has become the face of no-rules fighting in Europe. His aggressive style and willingness to compete under the most extreme conditions elevate him above fighters who benefit from more structured environments.
12. Barrie Jones -- BKB
Jones made one of the most dramatic entrances into the rankings of any fighter in 2025, knocking out BYB Light Heavyweight champion Gregoris Cisneros in just 16 seconds. That kind of finishing power in a championship context demands recognition.
13. Orsu Corsu -- KOTS
The French fighter is widely regarded as the most technically skilled competitor in KOTS history. In an organization where raw aggression often trumps technique, Corsu has demonstrated that clean boxing and intelligent fight management can win even under no-rules conditions. His ability to outclass opponents in the KOTS format puts him in rare company.
14. Jamie Driver -- BKB Welterweight Champion
Driver was the biggest mover in the 2025 bare knuckle rankings, jumping from #9 to #6 on Bare Knuckle Nation's list after a strong run of performances. Her dominant unanimous decision over Helen Peralta at BKB 42 in Nashville -- 50-45 across the board -- was one of the most complete performances by any fighter, male or female, in bare knuckle competition in 2025. Driver's inclusion in the overall P4P list reflects the quality of her opposition and the dominance of her victories.
15. Lorenzo Hunt -- BKFC Champion
Hunt earned his belt with a split decision over Chris Camozzi at BKFC 83 in October 2025. "The Juggernaut" brings a blend of power and pressure that has proven effective in the bare knuckle format, and his championship victory caps a steady rise through the BKFC ranks.
Best Bare Knuckle Fighters (Sanctioned Organizations)
These rankings cover fighters competing in BKFC, BKB, Gamebred Bareknuckle MMA, and other state-sanctioned bare knuckle promotions.
| Rank | Fighter | Organization | Division | Key Stat |
|---|---|---|---|---|
| 1 | Austin Trout | BKFC | Lightweight | 5-0, #1 P4P in BKFC |
| 2 | Kai Stewart | BKFC | Featherweight | 8-0, 4 title defenses |
| 3 | Mike Perry | BKFC | Middleweight | 6-0, "King of Violence" |
| 4 | LT Nelson | BKB | -- | #2 cross-org P4P |
| 5 | Naim Davudov | Top Dog FC | -- | #6 cross-org P4P |
| 6 | David Mundell | BKFC | -- | R1 KO for title |
| 7 | Gustavo Trujillo | BKB | -- | Top 5 cross-org |
| 8 | Alessio Sakara | BKFC | Cruiserweight | Champion, UFC vet |
| 9 | Alberto Blas | BKFC | -- | Consistent top-6 BKFC ranking |
| 10 | Barrie Jones | BKB | Light Heavyweight | 16-second KO for title |
The bare knuckle rankings are dominated by BKFC and BKB fighters, which reflects the reality that these two promotions run the most events, attract the deepest talent pools, and operate under the most rigorous competitive structures. Top Dog FC places Davudov in the top five, and the promotion's fighters would likely rank higher if they competed against Western opponents more frequently -- the Eastern European bare knuckle scene remains somewhat isolated from the BKFC/BKB ecosystem.
Best Backyard Fighters
Ranking backyard fighters presents unique challenges. There are no official records in most cases, bouts are not sanctioned by athletic commissions, and the skill level varies dramatically from fight to fight. These rankings are based on demonstrated skill, win record (where verifiable), consistency, and impact on the scene.
| Rank | Fighter | Organization | Weight | Notable |
|---|---|---|---|---|
| 1 | ATrain (Alan Stephenson) | Streetbeefs | Middleweight | Pro MMA record 6-5; most technically skilled Streetbeefs fighter |
| 2 | Steve "Firechicken" Hagara | The Scrapyard | -- | Founder/fighter; built 1M+ sub channel |
| 3 | Unnamed top performers | Streetbeefs | Various | Multiple undefeated records on channel |
| 4 | Remdizz | KOTR UK | -- | Founder/host; competes at own events |
| 5 | Various Backyard Squabbles standouts | Backyard Squabbles | Various | Growing LA scene talent |
Streetbeefs dominates the backyard rankings because it produces more fights, more consistently, with a wider talent pool than any other backyard operation. ATrain stands alone at the top -- his clean striking, controlled technique, and professional MMA record set him apart from the vast majority of backyard fighters who compete on pure heart and adrenaline.
The Scrapyard has produced increasingly skilled fighters as the promotion has grown, and its willingness to bring in professional crossover names (like Demetrious Johnson for exhibition work) has elevated the skill ceiling of its regular competitors.
The backyard scene's biggest limitation for rankings purposes is the lack of consistent record-keeping. Most organizations do not maintain official win-loss records, and fighters frequently compete under nicknames that make tracking their careers difficult. As backyard fighting continues to professionalize, more structured ranking systems will likely emerge.
Best No-Rules Fighters
No-rules fighting -- where headbutts, soccer kicks, and various other techniques banned in sanctioned combat sports are permitted -- represents the most extreme end of the underground spectrum. These rankings primarily draw from KOTS and similar organizations.
| Rank | Fighter | Organization | Country | Notable |
|---|---|---|---|---|
| 1 | Bloodaxe | KOTS | USA | Most infamous KOTS regular; relentless aggression |
| 2 | Orsu Corsu | KOTS | France | Most technically skilled KOTS fighter |
| 3 | Bojan "Zelva" Kosednar | KOTS | Slovenia | Hooligan background; devastating power |
| 4 | Abner "Skullman" Lloveras | KOTS | Spain/Catalonia | Hardened street fighter; extreme durability |
| 5 | Alexander "Drago" Shapovalov | Top Dog FC | Russia | Elite striker in minimal-rules format |
| 6 | Gia "The Ogre" Torchinava | Top Dog FC | Georgia/Russia | Raw power, intimidation factor |
| 7 | Oleg "Fomich" Fomichev | Top Dog FC | Russia | Trilogy fight veteran |
| 8 | Danil "Regbist" Aleev | Top Dog FC | Russia | Top Dog founder and fighter |
| 9 | Various Strelka tournament winners | Strelka | Russia | Multiple tournament victories |
| 10 | Various KOTS regulars | KOTS | Europe | Consistent performers across events |
The no-rules category is the most difficult to rank definitively because these organizations are the least transparent about fighter records, medical outcomes, and competitive history. KOTS maintains an air of deliberate mystery, and fighter identities are often partially concealed. Top Dog FC and Strelka are more open, but their fighter rosters turn over frequently.
What is clear is that the no-rules fighters face the highest physical risk and require a unique combination of technical skill, mental toughness, and willingness to accept damage that fighters in more regulated environments never have to confront. Bloodaxe and Orsu Corsu sit atop these rankings because they have demonstrated both durability and skill across multiple events in the most demanding format available.
Best Women's Fighters
Women's underground and bare knuckle fighting has exploded in recent years, particularly in BKFC and BKB. These rankings reflect the current competitive landscape.
| Rank | Fighter | Organization | Division | Key Achievement |
|---|---|---|---|---|
| 1 | Christine Ferea | BKFC | Flyweight/Bantamweight | BKFC Flyweight Champion; "Queen of Violence" |
| 2 | Britain Hart | BKFC | Strawweight | Inaugural BKFC Strawweight Champion |
| 3 | Helen Peralta | BKB | Super Featherweight | BKB Super Featherweight Champion |
| 4 | Jamie Driver | BKB | Welterweight | BKB Welterweight Champion; biggest 2025 P4P mover |
| 5 | Jade Masson-Wong | BKFC | -- | #4 women's cross-org P4P |
| 6 | Paty Juarez | BKB | -- | #5 women's cross-org P4P |
| 7 | Bec Rawlings | BKFC | -- | Pioneer; rebounded with 2025 win |
| 8 | Khortni Kamyron | BKB | Super Lightweight | BKB Super Lightweight Champion |
| 9 | Tai Emery | BKFC | Strawweight/Flyweight | 2-2 record; title challenger |
| 10 | Christine Vicens | BKFC | -- | Consistent BKFC contender |
Christine Ferea: The Clear Number One
Christine Ferea, 42, has long been regarded as the best female fighter in bare knuckle boxing, and 2025 cemented that status. She won the inaugural "Queen of Violence" title by stopping Jessica Borga via fourth-round TKO at BKFC 82 in October 2025, adding the bantamweight title to her existing flyweight championship. She has twice defeated Britain Hart and has consistently faced the best competition available. Conor McGregor himself crowned her as Queen of Violence at the Prudential Center. Ferea is not just the best women's fighter in the underground scene -- she is one of the best pound-for-pound fighters, period.
Britain Hart: The Enduring Champion
Britain Hart holds the inaugural BKFC Women's Strawweight Championship and defended it successfully against Tai Emery at BKFC 71 in Dubai (April 2025), winning by unanimous decision. Hart's durability, work rate, and willingness to fight anyone have made her one of BKFC's most reliable champions. Her two losses to Ferea are the only blemishes on an otherwise dominant resume.
Helen Peralta: BKB's Standard-Bearer
Peralta brought MMA experience and ferocity to the bare knuckle world, winning the BKB Super Featherweight Championship. Though she lost a decisive bout to Jamie Driver at BKB 42 in Nashville (50-45 across all cards), her overall body of work and title across multiple weight classes keep her firmly in the top three.
The Rising Generation
Jamie Driver's emergence as a dominant force -- jumping from #9 to #6 on the cross-organizational P4P list -- signals a deepening of the women's talent pool. Jade Masson-Wong, Paty Juarez, and Khortni Kamyron are all establishing themselves as legitimate championship-level fighters. Tai Emery, despite a 2-2 record, brings a crossover appeal and athleticism that keeps her in the title conversation.
KOTS has also introduced women's competition through its "Queen of the Streets" division, featuring fighters like Yess Castro and Sofia "Geisha" Landi. These no-rules women's bouts represent the most extreme end of women's underground fighting and have drawn significant interest from the KOTS fanbase.
Methodology and Limitations
These rankings should be understood as informed editorial opinions, not official standings. The underground fighting scene lacks the centralized data infrastructure that makes precise rankings possible in mainstream combat sports. Specific limitations include:
Incomplete records. Many organizations do not maintain or publish official win-loss records. Backyard fighting channels rarely track fighter statistics in any systematic way.
Cross-promotional comparisons. A BKFC champion and a KOTS regular have never fought each other, and likely never will. Comparing them requires assumptions about how skills would translate across rulesets.
Format differences. Bare knuckle boxing, bare knuckle MMA, backyard MMA, and no-rules fighting are fundamentally different sports. A dominant bare knuckle boxer might struggle in a no-rules environment, and vice versa.
Access to information. Some organizations -- KOTS in particular -- deliberately limit the information available about their fighters. Rankings of KOTS competitors are based on publicly available footage and commentary rather than official records.
Despite these limitations, cross-organizational rankings serve an important function. They give fans a framework for understanding where their favorite fighters stand relative to the broader scene, and they highlight the athletes who deserve recognition beyond their home promotions.
The State of the Underground in 2026
The underground fighting scene has never been deeper, more diverse, or more talented than it is right now. The influx of former UFC and professional boxing veterans into bare knuckle promotions has raised the overall skill level dramatically. Conor McGregor's investment in BKFC and the $25 million tournament announced in 2025 have brought unprecedented financial stakes to bare knuckle competition. The BKB rebrand and VICE TV deal have given Dada 5000's promotion a mainstream platform.
At the same time, the grassroots underground scene continues to thrive. Streetbeefs is bigger than ever. The Scrapyard crossed one million YouTube subscribers. KOTS remains as extreme and mysterious as ever. New backyard operations are launching regularly, inspired by the success of the channels above them.
The fighters ranked here represent the best of that entire ecosystem -- from world champion boxers competing without gloves to street fighters who have never set foot in a professional gym. What unites them is a willingness to test themselves in formats that mainstream combat sports would never sanction, and a talent level that demands recognition regardless of the setting.
These rankings will be updated quarterly as the competitive landscape evolves. Fighters can move up by winning championship bouts, defeating ranked opponents, or demonstrating dominance in cross-promotional competition. They can move down through losses, inactivity, or the emergence of superior competition.
The underground fighting world does not stand still. Neither do these rankings.
