Karate Combat has confirmed that former UFC fighter Chris Barnett will make his promotional debut on December 5, facing Jonathan “Big Baby” Miller at KC58 in Miami. The event will be staged in The Pit, Karate Combat’s signature arena.
“Beastboy” Chris Barnett
Barnett’s arrival in Karate Combat marks a transition from a career spanning multiple organizations. He became a fan-favorite in the UFC’s heavyweight division. As he would often do, he would perform front flips if he won the fight, and he was a 300-pound man doing spin attacks. Barnett was officially removed from the UFC roster on November 10, 2025, after a final appearance against Hamdy Abdelwahab a month earlier.
