Top 20 Undefeated Fighters – Part One

Undefeated fighters in combat sports can give off a certain mystique. It is not as common in MMA as it is in boxing to see a fighter with over 20 fights who is undefeated. In MMA, the best fight the best earlier in their careers than in boxing.

This is a two-part series on the top 20 undefeated fighters in the sport of MMA. Here in part one, we will look at fighters 11 though 20.

First let’s look at the top fighters who lost their O’s in 2025.

Three of the five fighters from last year’s top 20 list lost their O’s in title fights.

12. Azamat Murzakanov (16-0, 6-0 UFC)

Murzakonov made his pro debut in February of 2010 and won via KO in just 10 seconds. He didn’t return to MMA until 2015 where he had a lot of success on the regional scene. In November of 2019, Murzakanov won a four-man, single night, open weight tournament for Brave Combat Federation.

In August of 2021, the light heavyweight impressed Dana White with a first round TKO over Matheus Scheffel on Dana White’s Contender Series, which earned the Russian a UFC contract.

Murzakanov made his UFC debut in March of 2022 with a third round flying knee knockout of Tafon Nchukwi that earned him a performance of the night bonus. He returned in August of 2022 and defeated Devin Clark by third round TKO.

in April of 2023, the Russian fighter defeated his first ranked opponent in Dustin Jacoby, by unanimous decision. In August of 2024, Murzakanov defeated another ranked fighter in Alonzo Menifield.

13. Muhammad Mokaev (16-0, 7-0 UFC)

After an extensive amateur career that saw him go undefeated with over 20 documented fights, Mokaev made his pro debut for the Brave Combat Federation in August of 2020. Mokaev went 4-0 for Brave CF and 6-0 overall before making his UFC debut at just 21 years of age.

Mokaev fought the last two fights on his UFC contract in March and July of 2024, defeating two UFC top ten fighters in Alex Perez and Manel Kape by unanimous decision. The UFC chose not to re-sign Mokaev, which is very rare when a fighter is coming off a win, let alone a top 10 undefeated fighter. It has been reported that UFC officials say Mokaev has been hard to deal with and his style is not the most exciting.

Mokaev returned to the Brave CF organization in December of 2024, defeating Jovincent So by first round D’arce choke submission.

After taking a karate fight where he won by second round body kick at a Karate Combat event in May, Mokaev went 2-0 in MMA in 2025. This included a second-round head kick KO over Gerard Burns (7-1) at Brave CF 100 in November.

16. Timur Khizriev (18-0, 4-0 PFL, 3-0 Bellator)

The 28-year-old is scheduled to fight fellow to young top prospect Jean Matsumoto (17-1) in February. A win over Matsumoto could put Basharat in the UFC bantamweight rankings and either way would very likely give him a ranked opponent next.

Note – Movlid Khaybulaev is on the honorable mentions list with an asterisk beside his record. After defeating Jesus Pinedo in the finals of the PFL world tournament in August, Khaybulaev tested positive for a banned substance (recombinant EPO). The PFL subsequently stripped him of his 2025 world tournament featherweight title, and he is facing a one-year suspension. The win still appears on his record and has not yet been turned to a no contest. It is noteworthy that Khaybulaev’s only no contest on his record came from what was originally a knockout loss to Daniel Pineda that was later overturned to a no contest after Pineda tested positive for a banned substance.
