10. Dominick "The Dominator" Cruz
At number 10 I have gone with arguably the greatest 135 pounder in MMA and UFC history. Cruz was the first-ever UFC Bantamweight champion and defended the belt twice before vacating it due to injury. However, he came back and regained his title in 2016 after defeating Tj Dillashaw in a controversial split decision. After his bout with Tj, Cruz defended the belt once more against arch-nemesis Uriah Faber before losing it against Cody Garbrandt. Cruz most recently fought Henry Cejudo at UFC 249 and was TKO'd in the second round.
9. Henry 'The Messenger" Cejudo
At number 9 is none other than the king of cringe himself "Triple C". Cejudo is not only an accomplished MMA fighter but also an accomplished wrestler. He won Olympic gold at the 2008 Olympics and was a two division UFC champion. He defeated Demetrius Johnson to obtain the UFC flyweight championship, which he defended once against Tj Dillashaw, and won the vacated bantamweight title against Marlon Moraes,. He defended the bantamweight title against Dominick Cruz before announcing his retirement during the post-fight interview of UFC 249.
8. Jose Aldo
At number 8 I have decided to put arguably the greatest MMA and UFC featherweight of all time. He holds the record UFC featherweight title defenses at 7. His notable wins include the likes of Uriah Faber, Cub Swanson, Frankie Edgar, and Chad Mendes. However, his form has dipped ever since losing to Conor Mcgregor. He eventually moved down to bantamweight in 2019 where he has gone 0-2 and challenged for the vacated bantamweight championship which he lost by TKO in the fifth round to the current champion Petr Yan.
7. Khabib "The Eagle" Nurmagomedov
It is impossible to talk about the greatest UFC fighters without mentioning Khabib. He holds a PERFECT 28-0 record and has successfully defended his lightweight title twice against Conor Mcgregor and Dustin Poirier. He won the vacated title against Al Iaquinta. He holds notable wins against Edson Barboza, Conor Mcgregor, Dustin Poirier, Rafael Dos Anjos, and Michael Johnson. Khabib has also only lost one round in his entire UFC career which just shows off how dominant his wrestling style of fighting is. He has mauled his opponents in dominant performances and that's exactly why he's on this list.
6. Daniel "DC" Cormier
At number 6 is Daniel Cormier. He became a UFC fighter after strikeforce was absorbed into the UFC. He won 4 fights straight to earn his first title shot however, he came short and was defeated by his arch-nemesis Jon Jones by unanimous decision. However, he came back strongly after winning the vacated UFC light-heavyweight championship against Anthony Johnson. He then defended his belt against Alexander Gustaffson and once again came up short against Jon Jones however, this time Jones had failed a drug test and the fight was ruled a no contest. DC defended his title once more against Volkan Oezdemir before deciding to move up to Heavyweight were, he defeated the champion Stipe Miocic by KO in the very first round. DC defended the belt once against Derrick Lewis before losing the rematch and trilogy fights against Stipe Miocic. DC decided to retire after a stellar career which included notable wins against Stipe Miocic, Anthony Johnson, Alexander Gustaffson, and even MMA legend Dan Henderson.
5. Stipe Miocic
At number 5 is Stipe Miocic. His placement on this list was decided this August at UFC 252 after he defeated Daniel Cormier via unanimous decision to complete their trilogy. He holds the record number of defences of the heavyweight title (3 defences). He first won the belt against Fabricio Werdum and defended it against Junior Dos Santos, Alistair Overeem and Francis Ngannou. He lost the title to Daniel Cormier however, got his revenge after KO DC in 2019, and completing the trilogy in August of this year establishing himself as the UFC heavyweight GOAT.
4. Demetrius "Mighty Mouse" Johnson
At number 4 is Demetrius Johnson. The man with a record 11 UFC title defences. The main reason he is not higher on this list is because of the poor quality of fighters in the UFC flyweight division. However, this did not mean he didn't have interesting/exciting bouts/performances, just look at his flying armbar victory over Ray Borg! He was eventually dethroned by Henry Cejudo in 2018 by a close decision which arguably Johnson won. His trilogy bout with Cejudo never happened due to Johnson leaving the UFC for ONE championship were he currently competes and is the 135 pound champion at the time of writing.
3. Anderson "The Spider" Silva
Coming in at number 3 on this list is without a doubt the UFC and MMA middleweight GOAT. Anderson accumulated 10 UFC title defences over his dominant reign over the middleweight division. This included a 16 fight win streak which, included only 2 decisions! (3 submissions and 11 KO/TKO's!). Silva eventually lost his title against Chris Weidmann and was never able to find that same form again going 1-6 1NC. His next bout is scheduled on Halloween this year against Uriah Hall and will likely be his final ever bout.
2. Georges "Rush" St-Pierre
The toughest decision for me in this list was ranking the top 2. At number 2 I have gone for GSP. He has 9 consecutive title defences and won a title in a 2nd division after defeating Michael Bisping for the middleweight title in his comeback fight in 2017. He first title bout ended in defeat by armbar to MMA and UFC legend Matt Hughes. Despite this setback, GSP earned and won his rematch before losing it in a shocking result in his bout against Matt Serra. GSP won two fights after his second career loss (one of these being a trilogy with Matt Hughes for the interim title) and rematched Matt Serra at UFC 83 and won the bout by KO/TKO. His notable wins include those against Matt Hughes(x2), Bj Penn(x2), Carlos Condit, Nick Diaz, and Michael Bisping. His 13 fight win streak is still technically active if he decides to come back and fight again although this is unlikely.
1. Jon "Bones" Jones
To complete this list is none other than Jon Jones. He is probably the most controversial fighter on this list due to failed drug tests and other incidents outside of the octagon. However, inside of it, this man is a beast! He has used his high-level wrestling combined with high level striking to dismantle all of his opponents. His almost perfect 26-1-0 1 NC record shows how good this man is. His only loss in the UFC was a disqualification against Matt Hamill, which was due to an illegal 12 to 6 elbow being thrown by Jones. Jones only NC was in his overturned 2nd round KO victory against Daniel Cormier after his drug test came back as positive. Jones has won a record 14 title fights and some of his most notable wins are against Mauricio Rua, Rampage Jackson, Rashad Evans, Vitor Belfort, Alexander Gustaffson(x2), and Daniel Cormier. Jones has recently vacated the light-heavyweight title in hopes he can add his name to a list of two division champions as he will be taking a step up in weight moving to heavyweight.
