A robot fight club dodged California’s ban by taking the human out of the cage
A cease-and-desist over unlicensed human-robot cage fights didn't stop the matches. It just changed who was standing inside the cage.
A San Francisco promoter put a remote-controlled humanoid robot in a cage with a human fighter on September 18, 2026, and filmed it. Soon after, the state of California told the company to stop.
The fighter was content creator Frankie LaPenna. His opponent was a six-foot humanoid called the T800, built by the Shenzhen startup EngineAI and modeled on the robot from the Terminator films. A person standing outside the cage controlled its every move.
LaPenna hurt his hand striking the robot’s metal frame. Footage of the bout reached more than eight million views.
On September 30, the California State Athletic Commission sent the promoter, Robot Entertainment Kombat, a cease-and-desist letter. State law gives the commission authority over any boxing or mixed martial arts contest that involves a human, and the letter warned that promoting an unlicensed one is a misdemeanor.
“Unsanctioned activity puts the physical and financial well-being of all those involved at risk, and such activity will not be tolerated,” the commission wrote, adding that it would consider new guidance as robot technology evolves.
Robot Entertainment Kombat’s founder, Cix Liv, treated the letter as a trophy. He posted it online with the caption “We made it, boys.”
The law clearly states that a match is between two persons.
Liv’s argument was that regulators would have to convince a court a humanoid counts as a person. He did not wait for one to decide. On October 11, the company staged a different kind of bout at its arena on Van Ness Avenue, a former mattress showroom.
Two machines, named Rektile and T-REK, fought each other with steel claws and blades of hardened AR500 steel up to 20 inches long. People outside the cage controlled both of them. No human stepped inside it.
More than 100 people paid $69 a ticket. A camera lens was pierced and the cage took gouges. Nobody in the crowd was hurt.
No robot in either fight is something a reader could buy. But the back and forth is an early look at how a state regulator treats a humanoid robot built to perform for an audience, not to do a job.
Other companies are now pitching general-purpose humanoids for homes and warehouses. California’s rule, as written, applies only when a human steps into the contest, and the October rematch made sure one did not.
Neither bout shows a robot fighting without a person running it. A pilot outside the cage controlled the T800 that hurt LaPenna’s hand, and pilots controlled Rektile and T-REK on October 11. Every strike in both fights traces back to a human hand on a controller.
The cease-and-desist does not settle Liv’s legal argument, either. It shows only that the commission’s authority depends on a human being inside the cage, which is exactly the condition the October bout removed.
An engineer working on Robot Entertainment Kombat’s machines, who goes by Dobrikov, said the team wants robots that do more damage to each other. His own dream build, he said, has a hydraulic claw on one side and a spinning saw on the other.
