California Targets Human-vs-Robot Cage Fight With Legal Order

California challenges REK's human-vs-robot fight

On September 18 in San Francisco, influencer Frankie LaPenna stepped into an octagon against three humanoid robots, each remotely controlled by a human operator, in separate MMA-style bouts, winning two of three. Robot Entertainment Kombat, the league behind the event, called it the first human-vs-robot fight in history, and videos of the bouts have drawn more than 10 million views on YouTube.

On September 23 the California State Athletic Commission sent a cease-and-desist letter to REK and its CEO Cix Liv, arguing that any boxing or MMA contest involving a human in California requires the commission's prior approval and that holding one without a license is a misdemeanor.

Liv does not appear concerned. He posted the commission's letter on X with the caption "We made it boys" and told the Los Angeles Times by email that the law requires "two persons" for a bout to count as real boxing, so regulators would have to argue "that actuators are somehow persons." He added that even a fine would just mean nonstop media coverage.

REK stages a weapons-equipped Deathmatch

On the 9th in San Francisco, REK held a humanoid robot event called Deathmatch, whose main bout pitted one robot about 188 centimeters tall and 82 kilograms against an opponent about 180 centimeters and 86 kilograms, one fitted with steel claws and the other with a long sword.

UFB's Austin stop disappears, Shanghai club unconfirmed

Ultimate Bots' Season 2 schedule no longer includes a planned stop at F1 Austin, with no explanation offered by the league. Earlier versions of the schedule page marked the Austin date as sold out, suggesting it may have been a private appearance rather than a public fight night.

Separately, local reports say a humanoid robot fighting club is planned to open at Baoshan Smart Bay in Shanghai in October, but no opening date, ticketing or fight format has been published, and as of mid-October there is no sign it has opened. The claim traces to a single league event, and outlets disagree on the title of the organizer, Zhang, calling her either general manager of the Shanghai Robot Industrial Park or chairman of a separate robotics firm.

New hardware raises the stakes

The Booster T2 runs on an Nvidia Jetson Thor chip rated at 2,070 teraflops, far above the 100 teraflops on the Unitree G1's Jetson Orin. Third-party retailers price it around 27,000 euros, roughly $29,000, about double the cost of a G1. Demonstrations show it sprinting across surfaces, jumping and performing a wall flip, but Booster has not released footage showcasing its dexterity.

In Moscow, EngineAI's T800 made its Russian debut on October 7 at Moskino Film Factory's Robot Show. Nine humanoids, including the Unitree G1 and the T800, took part in a segment called Steel Instincts, pairing with human performers who demonstrated moves the robots then repeated. The T800 stands 173 centimeters tall and weighs up to 85 kilograms, built from aerospace-grade aluminum and titanium. An earlier segment featured two teleoperated combat robots fighting while digital characters mirrored them on screen, and a separate segment had motion-capture performers whose movements were copied onto digital robots.

Military commentators eye combat robots

Former Ukrainian commander-in-chief Alexander Syrsky said humanoid combat robots are already being tested and could reshape battlefield tactics as military AI advances, describing the shift as moving from theoretical research to practical trials. He also pointed to AI-powered control systems being added to conventional weapons. Russian military expert Yuri Knutov separately predicted robotic platforms could begin replacing soldiers on front lines within three to five years.
