Rreza Arianto Record: 5-1-0

One Pride dominance

The bulk of Arianto's career unfolded under the One Pride banner, where he reeled off five straight wins. He debuted in December 2019 with a first-round ground-and-pound stoppage of Haulian Gultom at One Pride MMA Fight Night 35, then returned in October 2020 to finish Andre Setyawan by ground-and-pound at Fight Night 38. He kept the momentum going in 2021, submitting Zainal Abidin Bahri by first-round rear-naked choke at Fight Night 44 and stopping Michael Mataheru with first-round ground-and-pound at Fight Night 50. He capped the run in October 2022 by outpointing the unbeaten Muhammad Hanwa over the distance at Fight Night 63, his lone decision and a win that pushed him to 5-0.

Stepping up at Cage Warriors

That unbeaten record earned Arianto a place on the international stage at Cage Warriors 164 in November 2023, one of three Indonesian fighters featured on the card. There he ran into the toughest test of his career in Julien Pierre Lopez, who handed him his first professional defeat by second-round strikes. It was a hard introduction to a deeper talent pool, but at just 23 and carrying a 5-1 record built almost entirely on finishes, Arianto remains an aggressive lightweight with room to grow.

Fighting style

Arianto is a relentless, forward-pressing finisher, true to his "Crazy Lion" nickname. Four of his five wins have come by stoppage – three by knockout or ground-and-pound and one by submission – for an 80% finish rate, and his bread-and-butter is heavy top control followed by punishing ground-and-pound. He blends takedowns with first-round aggression, looking to overwhelm opponents early rather than grind out decisions. The loss to Lopez showed the gap that still exists against more polished international strikers, but his finishing instinct and physicality make him a dangerous out for anyone in the regional lightweight ranks.
