Legit, Yoshua Marcellos Is Changing The Industry

Every fight scene reaches a point where things need to move forward. In Indonesia, that momentum is being led by Yoshua “Celloz” Marcellos. Through BYON Combat and BYON Media, he’s building something that didn’t really exist, a structure that treats combat sports not just as a spectacle, but as an actual industry.

Before this, most events were run by people who either based their ideas on how things used to be or tried to copy what they saw on social media, thinking that would be enough. BYON Combat Showbiz Vol. 5, held on June 28, 2025, at Tennis Indoor Senayan, showed what happens when a fight night is planned, executed, and positioned like a real product.
Modified kickstriking, no elbows, limited clinch time, and no sweeps. That pacing made the action faster and easier to follow, especially for fans watching through PPV on Vidio.

 Across eleven fights, the card featured both local and international fighters, and several titles were on the line. Surya “The Pretty Boy” Dharma stopped Puriwat Taousuwat in the first round to win the WBC Youth title. Andi Cobra beat Jaden Bahtera by TKO in the fourth to claim the ICB national belt. Danar Ilmawan and Aziz Calim also walked away with national titles in their respective divisions.

But the real story wasn’t just about the winners. This event also exposed what still needs work. Jemz Mokoginta, Brian Lawitan, and a few others who were seen as future stars lost their fights. Some fans called them "anak emas," and seeing them fall reminded everyone that favoritism won’t save you in the ring. Those losses were a good thing. They showed the matchmaking isn’t soft and the pressure is real.

More importantly, the industry around the event is starting to look different. On June 19, 2025, just days before the show, the Uni-Combat Council (UCC) was officially established at Bakrie Tower in Jakarta. It’s a joint effort by BYON Combat, Emtek Group, and One Pride MMA, with support from the Ministry of Youth and Sports. The UCC is led by Chairman Nelson Nainggolan and Secretary General Abel Mamesah, with backing from names like Ardi Bakrie and Indra Yudhistira. Its goal is to clean up, organize, and professionalize combat sports in Indonesia and across the region. For the first time, there’s a real neutral body meant to watch over rules, matchmaking, safety, and standards.

He’s creating something that works, something fighters and fans can actually rely on. Tryouts, structured programs, regular fights, and visibility for fighters, it’s the kind of work that helps a scene grow without burning out.

BYON doesn’t try to be the UFC or ONE Championship. The content, the characters, and the pacing are shaped for the Indonesian audience, other promoters and gyms are starting to take notice. Visuals are sharper. Fighters are more marketable. Even sponsors are watching more closely. That shift doesn’t happen overnight, but it’s happening.

If this industry ends up becoming something solid, where fighters get paid well, fans stay invested, and events can hold their own internationally, it will be because people like Yoshua “Celloz” Marcellos didn’t wait around for someone else to figure it out.
He’s already building it. Piece by piece.
