The Big Four Robo is a giant indestructable robot created when the Crime Big Four combine themselves. It is incredibly tough as both the Gorangers' and JAKQ's own attacks and moves put no dent into this massive machine. The only way it was defeated was when JAKQ and Goranger combined their most powerful weapons together to destroy the robot.
