After the events of Worlds Collide, Ra Moon betrays Dr. Wily and uses its cables to reveal its plans and its past.

Dr. Wily attempted to weaken Ra Moon by sending Ra Thor, but Ra Moon was easily able to take control of the new Robot Master, due to it being built from the supercomputer's technology. Ra Moon then removes the EMP immunity from the MM2 Robot Masters, leaving Mega Man and the rest of Light's Robot Masters to deal with Ra Thor, Magnet Man, Hard Man, Top Man and Spark Man. Losing his temper, Mega Man uses a barrage of Special Weapons to destroy Ra Thor. Ra Moon then reveals that used the blueprints of the Yellow Devil to create his own version, the Ra Devil, and brings him out into the battle. After learning from his nemesis Wily that Ra Moon is directly powering the Ra Devil, Mega Man uses two Mega Busters to shoot Ra Moon, ending it's EM wave, dissolving Ra Devil, and freeing the MM3 Robot Masters from it's control. Defeated and shutting down, Ra Moon sends a final message to it's "children", the Stardroids, to avenge it. (MM #29, #30, #31, #32)
