The California State Athletic Commission (CSAC) has issued a cease and desist order to Robot Entertainment Kombat (REK), a San Francisco-based startup specializing in human versus humanoid robot cage fights. The regulatory action follows an unauthorized event on September 18, 2026, where YouTuber Frankie LaPenna competed against three humanoid robots. Video footage from the event showed the robots delivering significant strikes, including kicks that sent LaPenna across the cage. While LaPenna reportedly won the series of bouts, the CSAC stated that organizing, promoting, or sponsoring such matches without a license constitutes a misdemeanor under California law. The commission’s order mandates that REK immediately stop hosting, promoting, or advertising unsanctioned bouts. While the order focuses on the failure to secure required permits for full-contact martial arts rather than the legality of the robots themselves, the agency maintains the authority to veto such events on a case-by-case basis. REK founder Cix Liv has shared the legal notices on social media. New details regarding the September 18 match reveal that while the machine appeared autonomous, it was actually being operated by a human pilot using a remote virtual reality system. The robot used in the spectacle was an EngineAI model modified for the event, featuring a head design reminiscent of the ‘Terminator’. The CSAC has asserted jurisdiction over the matches due to their commercial nature and the involvement of human combatants, noting that future matches involving humans cannot proceed without official state authorization.
