Four days before Alexander Volkanovski tries to take a big piece of his legacy in Abu Dhabi, Jose Aldo spent an interview with MMA Fighting doing two things that sound like they shouldn’t fit together. He explained why he’d show Movsar Evloev the door if he ran the UFC. Then he said he hopes Volkanovski beats Evloev, even if that win pushes Volk past him in the featherweight record book.
That combination is about as Aldo as it gets. He has always fought like a man with a grudge and talked like a man without an ego.

From Manaus to Rio with a bag of clothes
Aldo was born on Sept. 9, 1986, in Manaus, Brazil. As an infant, a crib he was lying in got thrown onto a barbecue, which is where the scar on the left side of his face comes from. As a teenager he wanted to be a professional soccer player, and his father backed the dream. What actually pushed him toward fighting was simpler and less romantic. He was tired of losing street fights.
So he started training capoeira, often outdoors after class, and that’s where a Brazilian jiu-jitsu coach spotted him and invited him to a session. One session was enough. He dropped capoeira, took up jiu-jitsu, and at 17 left Manaus for Rio de Janeiro with nothing but his clothes. He landed at Nova União, the gym he still represents, alongside future bantamweight champ Renan Barão.
His pro debut came at 17, at EcoFight 1 on Aug. 10, 2004, and it lasted 16 seconds. His early run reads like a highlight reel stitched together in a hurry: a flying knee that opened a cut and ended a fight on a doctor stoppage, a 20-second knockout built on knees and soccer kicks, a TKO in England in 1:05.
Then came the loss that shaped everything after it. In November 2005, Aldo moved up to lightweight at Jungle Fight 5 and faced Luta Livre black belt Luciano Azevedo. He won the first round with combinations and leg kicks, but Azevedo eventually got him down, climbed to mount, took his back and finished a rear-naked choke at 3:37 of Round 2.
Aldo would not lose again for more than 10 years.
The run
After Azevedo, Aldo won 18 straight. The WEC got him in 2008, and that’s when the rest of the sport started paying attention. At WEC 41 in June 2009, he hit Cub Swanson with a double flying knee eight seconds into the fight. Five months later he took the WEC featherweight title from Mike Brown, finishing him from back mount at 1:20 of Round 2. Sherdog and MMA Live both named him 2009 Fighter of the Year.
The Urijah Faber fight at WEC 48 in April 2010 is the one I’d hand to anyone who thinks leg kicks are a decoration. Aldo threw 32 leg and body kicks, dropped Faber with them more than once, and won 49-45, 49-45 and 50-45. When the WEC folded into the UFC, Aldo was handed the first UFC featherweight belt at UFC 123 in November 2010.
He defended it seven times. The one people remember is Chad Mendes at UFC 142 in Rio in January 2012, a knockout in the last second of the first round followed by Aldo sprinting out of the cage and into the crowd. The rematch at UFC 179 was the better fight, honestly, with Mendes dropping him early and rocking him in the third while Aldo scored two knockdowns of his own and took a unanimous decision that multiple outlets named Fight of the Year. In between he beat Frankie Edgar, Mark Hominick, Kenny Florian, Ricardo Lamas and Chan Sung Jung.

The numbers that matter in GOAT arguments: Jed Meshew of MMA Fighting counts 11 title wins for Aldo, 10 of them in a row. Fight Matrix ranks him the greatest featherweight ever and third pound for pound.
The fall, and the stubbornness after it
December 12, 2015, UFC 194. Conor McGregor knocked him out 13 seconds in, ending a 15-fight featherweight win streak and handing Aldo his first loss at 145. A lot of champions would have drifted after that. Aldo beat Edgar again at UFC 200 for the interim belt and was promoted back to full champion on Nov. 26, 2016, when McGregor was stripped without ever defending.
Then came Max Holloway, twice. At UFC 212 Aldo won the first two rounds on every scorecard before getting stopped in the third. At UFC 218 the fight played out almost the same way. For a guy whose early pro career included “a seemingly exhausted” third round against Thiago Meller, as his Wikipedia entry puts it, the late-round fade against Holloway felt like an old ghost coming back. I’m a cardio guy. Those two fights are the clearest data point in his whole career.
He bounced back by dropping Jeremy Stephens with a left hook to the body in 2018, his first three-round fight in more than nine years. According to MMA Fighting, he later challenged for a bantamweight title at 33.
Where he stands now
The Knockout Daily rankings list Aldo at 32-10, No. 23 at featherweight, with his last fight on May 10, 2025. In the MMA Fighting interview he described himself as having stopped fighting.
That hasn’t softened him. Evloev, who is 10-0 in the UFC with 10 decisions, had told MMAjunkie that Aldo, Anderson Silva and Anthony Pettis didn’t stay “on the same level after doping tests.” Aldo’s answer was blunt. He said Evloev “is not a guy who really interests me,” and that as UFC president he’d keep him out of title fights entirely.
“I’d wait for him to lose for the first time and then cut him because he’s a guy who doesn’t sell, a guy who puts on boring fights, a guy who doesn’t draw attention,” Aldo told MMA Fighting.
On doping, he said he was tested constantly throughout his career and nothing ever turned up. He claimed that before UFC 194 he was tested three times a day while McGregor was tested only on fight day. Then he refused to use it as an excuse.

“No, I lost because the guy landed a good shot on me, regardless of whether he was on something or not, and he won the fight,” Aldo said.
You can disagree with his matchmaking philosophy (I’d point out that 10-0 against UFC competition is a decent sales pitch on its own), but a man owning a 13-second knockout a decade later earns some credit.
Aldo still has admirers in high places, too. Jorge Masvidal, asked about Aldo against Islam Makhachev or Khabib Nurmagomedov, said in a clip posted on X by Dovy: “The only guy I would send in there to fight them is Aldo. He would probably beat them all.”
What’s next
Aldo isn’t the one fighting next. It’s his record that’s at stake. Mike Heck wrote in MMA Fighting’s UFC 333 roundtable that a Volkanovski win over Evloev would break Aldo’s UFC title fight win mark, tie his defense record and settle the featherweight GOAT debate. Meshew disagreed, arguing a win would move Volk to nine title wins against Aldo’s 11 and only make it a real conversation.
Aldo says he doesn’t care either way. He said Volkanovski and Holloway arrived near the end of his career and he has a soft spot for both.
“I have absolutely no problem with him surpassing me or tying my record,” Aldo said. He described a champion’s life as “killing a lion every single day,” and said he roots for fighters to win titles so they can build something for their families.
He’ll be pulling for the Australian when Volkanovski and Evloev headline UFC 333 in Abu Dhabi on Oct. 24, and the guy he’s cheering for is the one who could finally take his crown.
