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.
