Chris “Beastboy”Barnett

Chris Barnett is a professional heavyweight mixed martial artist known as “Beastboy.” Born on June 14, 1986, in Spain, he stands 5 feet 9 inches tall and represents Hardcore Gym. Barnett began competing professionally in 2009 and developed a reputation for an entertaining, unpredictable approach built around striking, athletic movement and showmanship.

Barnett joined the UFC in 2021 and earned one of his most notable promotional victories at UFC 268, stopping Gian Villante with strikes before celebrating with an acrobatic backflip. He later returned from an extended absence to compete at UFC 308 in October 2024 and faced Hamdy Abdelwahab at UFC 321 on October 25, 2025. His UFC contract ended after that bout, according to MMA Fighting’s report dated November 11, 2025.

As of October 2, 2026, Barnett is no longer a UFC fighter. MMA Fighting reported on August 26, 2026, that he had signed with Power Slap, while also noting his continued involvement in combat sports beyond MMA. Barnett’s UFC profile identifies boxing as his listed fighting style, and his own UFC questionnaire highlights striking and grappling training, including a preference for the flying armbar and tornado kick.
