A short-notice opportunity transformed Antonio "The Flash" Cesar from newcomer to contender in a single night. Next up, he finds out whether that leap was real.
The Brazilian returns to the flyweight division against unbeaten Joshua Perreira at ONE Fight Night 48, broadcasting live in U.S. primetime from Bangkok's Lumpinee Stadium on Friday, October 2. Cesar enters with a 14-2 overall record and a nine-fight winning streak, the most recent result a unanimous decision over Lito Adiwang this past July after stepping in as a replacement for Perreira himself following an injury.
Perreira brings a perfect 6-0 record into the rescheduled matchup, representing the Immortal Martial Arts camp under the guidance of former UFC veteran Matt Brown. His most recent showcase came via a 38-second spinning backfist knockout of Gilbert Nakatani, though his actual promotional debut ended in a no contest after ACL surgery, making October 2 his first true test since that setback.
Cesar turned professional at 17, building his regional résumé to a three-time Mr. Cage Flyweight Championship before ONE Championship came calling. He credits a specific mentality for the run that followed.
"I always knew I could become a fighter. I realized talent alone wasn't enough. You had to be the hardest worker, and I always heard that the sky was the limit for me," he said.
That belief was tested well outside the cage. Cesar lost a sister in 2020 and a brother roughly two years later, absorbing both tragedies without ever stepping away from training.
"Even while going through those losses, I never stopped training. Now, it has become an even greater motivation for me to honor my siblings," he said. "Training and competing also helped me a lot to overcome grief. First and foremost, I overcame it through the grace of God, praying and seeking Him."
The stakes extend well beyond the immediate result. Cesar's nine-fight streak stands as the longest active run either man will carry into the cage, and a flyweight division already stacked with unbeaten talent means the loser's stock could fall sharply.
"I like training, preparing, and winning. If I keep winning, I can help the people around me and change my life, my wife's life, and my family's life," he said.
