Mega Man V
All the Stardroids first appeared in MegaMan V. Dr. Wily found them in some unknown ruins and decided to use them for conquering the world. With this they were brought back online and attacked the world, being led by Terra. MegaMan, after being defeated by Terra, was then given the new Mega Arm and was dispatched to defeat them. After defeating four of the robots and Dark Moon, the battle soon shifted to space itself where he defeated the last four robots, and finally in a rematch against Terra where he own. On the Wily Star, Mega Man after defeating the Mega Man Killers, rematched against the Stardroids, except Terra. Soon after defeating Dr. Wily, the scientist released another robot, excavated from the same ruins, the doomsday weapon Sunstar, however Sunstar would not obey Wily and attacked him causing him to retreat. Sunstar then faced MegaMan and after three phases was defeated. The robot was surprised when his enemy showed kindness to him, but he would never known as his fusion reactor soon exploded taking the Wily Star and him with it.
