Guilherme Pat might not be a household name yet, but that’s quickly changing in 2026. The Brazilian heavyweight, nicknamed “Kong,” has quietly built an undefeated record while navigating one of the toughest divisions in MMA. At a time when the UFC heavyweight landscape is constantly shifting, Pat has started to stand out—not just for his size and power, but for the journey it took to even get inside the Octagon.
Standing at 6’6” with a long reach, Pat carries the kind of physical presence that instantly grabs attention. But beyond the frame, it’s his composure and finishing ability that have people taking notice.
Pat entered the UFC in late 2025 and made an immediate impression. He picked up a win in his debut against fellow undefeated fighter Allen Frye, showing he could handle the step up in competition. It wasn’t a flashy knockout, but it was the kind of performance that told matchmakers he belongs.
Before that, Pat had already built momentum on the regional circuit. With multiple knockout wins early in his career, he developed a reputation as a dangerous finisher. Four of his six wins have come via KO, which is exactly what you want to see from a rising heavyweight.

What makes Pat interesting is that he doesn’t rush things. For a division known for chaos, he fights with patience, picking his shots and managing distance well for someone his size. That approach has helped him stay undefeated, but 2026 is shaping up to be a real test. His upcoming fight against Thomas Petersen is being viewed as a key moment.
While most fighters worry about rankings and opponents, Pat’s biggest hurdle came outside the cage. Before even getting his UFC opportunity, he faced repeated U.S. visa denials that delayed his career at a critical stage.
At one point, Pat had to turn down or miss out on major opportunities, including a shot on Dana White’s Contender Series. For a fighter trying to break through, that kind of setback can be devastating. Momentum matters in MMA, and being stuck on the sidelines due to paperwork is the last thing anyone wants.

Instead of letting it derail him, Pat stayed active wherever he could and kept building his record. Eventually, the UFC signed him directly, recognizing both his talent and the unusual circumstances that had held him back. Now, with those obstacles behind him, 2026 feels like the year where everything finally lines up.
