|This article is about a/an kaijin in Kamen Rider Black RX.|
Cublican is a robot Gatezawn sent after Kohtaro armed with a claw for the left hand and a heat laser gun for the right hand. He disguised himself as a human and after stealing a car, he stole some of Hayami's clothes. He attacked Kohtaro, Reiko & the Sahara Kids with said car. When Kohtaro's attempt to stop him by jumping off the car failed, they end up in abandoned warehouse and fought. After being blasted down from a higher level, Kohtaro saw the sun light in a hole in the roof and transformed. The two then fought with the robot falling onto an electrical outlet. When exposed after his synthetic skin catches fire, Cublican fought Kohtaro. Taking the fight to a Quarry, Kohtaro's RX Kick knocked the robot's head off, only for it to grow a new one in the form of a napalm cannon. RX absorbed the sun's rays to recharge before calling for Acrobatter. Cublican was the first Crisis Empire monster to be destroyed by the Revolcane.
