The announcement of the main event has electrified MMA fans in Brazil. Charles, one of the country’s biggest sporting idols, carries the responsibility of breaking the streak of Brazilian losses in UFC main events in 2025.

Charles’ return to Brazil
Charles do Bronx’s return to Brazil is a milestone for national MMA. Since his last fight on Brazilian soil in 2020 against Kevin Lee in Brasília, the fighter hasn’t performed before local fans. At 35, the former lightweight champion boasts 35 wins and 11 losses, with a record reflecting his versatility and jiu-jitsu prowess. The loss to Topuria in a vacant title fight was a significant setback, but Charles showed resilience by accepting a high-level challenge just three months later. The Rio fight will be his seventh in Brazil, his first in the city, raising fans’ expectations.
Choosing Charles as the UFC Rio headliner reflects his popularity and commercial appeal. He has publicly expressed his desire to fight in Brazil, and the UFC, aware of his ability to fill arenas, is banking on his charisma to ensure the event’s success. Farmasi Arena, the venue for UFC 301 in May 2024, will again be the spotlight, with a capacity for around 15,000 spectators.
Rafael Fiziev: A dangerous opponent
Rafael Fiziev, born in Kazakhstan and naturalized Azerbaijani, is an opponent set to test Charles’ skills. Currently ranked tenth in the lightweight division, Fiziev is known for his aggressive style and refined striking, rooted in muay thai. He comes off a unanimous decision win over Ignacio Bahamondes in June 2025, after recovering from a serious knee injury that sidelined him for nearly a year. With 13 wins and four losses in the UFC, Fiziev has faced names like Justin Gaethje and Rafael dos Anjos, proving his ability to compete with the division’s elite.
- Muay thai specialist, with knockouts over Moicano and Dos Anjos.
- Suffered losses to Gaethje, Gamrot, and Tsarukyan before his latest win.
- Expressed desire to face Charles since 2022 via social media.
- Trains in Thailand, honing his striking skills.
The matchup with Charles is a unique opportunity for Fiziev. Facing the fourth-ranked lightweight is a crucial step toward a title shot. His excitement was clear in social media posts, where he highlighted the countdown to the fight.
UFC’s strategy for the event
UFC Rio, set for October 11, is a strategic move by the organization. Hosting events in Brazil has always been a financial challenge, with high costs and a devalued currency. Selecting Charles do Bronx as the main attraction is an attempt to capitalize on his popularity to ensure ticket sales, a hurdle not always cleared in previous Rio events. Events like UFC 301, headlined by Alexandre Pantoja, and others with Glover Teixeira and Deiveson Figueiredo struggled to sell out, even with title fights.
The potential inclusion of Vicente Luque and Santiago Ponzinibbio in the card, still in negotiation, elevates the event’s caliber. Both are experienced welterweights known for thrilling fights, which could draw even more fans. Farmasi Arena, located in Rio’s west zone, is a modern venue suited for major events, but commercial success will hinge on fan turnout.
- UFC plans a robust card with prominent Brazilian fighters.
- Confirmed names include Vitor Petrino, Jhonata Diniz, and Bia Mesquita.
- Pre-sale tickets are already available for registered fans.
- Event comes 17 months after the last UFC in Brazil, in May 2024.
Charles’ history in Brazil
Charles do Bronx has an impeccable record in Brazil’s main events. He’s won every headlining fight in the country, including notable victories over Jeremy Stephens, Nik Lentz, and Kevin Lee. His last appearance in Brazil, in Brasília, was a jiu-jitsu masterclass, with a submission that thrilled the crowd. Now, in Rio, Charles faces an elite striker, promising a clash of styles. While Charles excels in submissions, with 20 in his career, Fiziev bets on striking to secure a knockout.
The pressure on Charles is high. No Brazilian has won a UFC main event in 2025, with losses from names like Pantoja and others in numbered events. The fight against Fiziev could be the chance to break this streak and reignite national MMA pride.
Clash of styles in the octagon
The Charles do Bronx vs. Rafael Fiziev fight promises a spectacle. Charles is renowned for his ground game, with a jiu-jitsu style that led to UFC submission records. Fiziev, conversely, is an elite striker with precise, powerful blows. The fight pits two distinct styles: Charles’ versatility against Fiziev’s striking aggression. Analysts suggest Charles will need to take the fight to the ground, while Fiziev will aim to keep it standing.
- Charles has 20 submissions in his 35 professional MMA wins.
- Fiziev knocked out seven opponents in his 13 UFC victories.
- Experts say the fight could end in a knockout or submission.
- The matchup tests Charles after his loss to Topuria.
Preparation will be key for both fighters. Charles, dealing with injuries post-Topuria, has less than four months to recover and train. Fiziev, showing resilience after his own injury, won in June, indicating he’ll be in top form.
Fan expectations and ranking impact
Brazilian fans are eager for Charles’ return. Social media posts reflect their excitement, seeing him as a chance to revive national MMA amid inconsistent results. For Charles, a win could put him back in the lightweight title race, currently led by Ilia Topuria. For Fiziev, a victory would be a leap toward the top five in the division.
UFC Rio also marks the organization’s return to Brazil after a 17-month hiatus. Choosing a Fight Night event, without a title on the line, is unusual for Charles, who hasn’t headlined one since 2020. The decision reflects the UFC’s confidence in his draw to fill seats, even without a belt at stake.
- Brazilian fans flooded social media with support for Charles.
- A win could position Charles for another title shot.
- Fiziev aims to break into the lightweight top 5 with a victory.
- The event is Charles’ first Fight Night since March 2020.
Other UFC Rio highlights
Beyond the main event, UFC Rio promises a stacked card with Brazilian talent. Vitor Petrino, Jhonata Diniz, Julia Polastri, Bia Mesquita, and Lucas Rocha are confirmed, showcasing a new generation of fighters. The possible Luque-Ponzinibbio fight adds veteran firepower, aiming for a memorable event. The UFC has opened ticket pre-sales, expecting a packed house, with Rio’s passionate MMA fans as a key factor.
The event is also a test for the UFC in the Brazilian market. After commercial challenges in prior editions, the organization bets on big names to ensure success. Charles, one of the sport’s biggest idols, is the main draw to attract crowds and justify high production costs.
