Mega Man V
All the Stardroids first appeared in Mega Man V. Dr. Wily found them in some unknown ruins and decided to use them to conquer the world. With this they were brought back online and attacked the world, being led by Terra. Mega Man, after being defeated by Terra, was then upgraded with the new Mega Arm and was dispatched to defeat them.

After defeating four of the Stardroids and Dark Moon, the battle soon shifted to space itself where he defeated the last four Stardroids, and finally in a rematch against Terra where he won. Mega Man than discovers that Dr. Wily was the leader of the Stardroids. On the Wily Star, Mega Man has a rematch against the Mega Man Killers, Quint, and eight of 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 Mega Man, and after three battle phases, was defeated. The robot was surprised when his enemy showed kindness and offered to repair him, as he believed robots could only fight, but he would never known if he could do more than fighting as his fusion reactor was critical and would soon explode. After Mega Man escapes from the fortress, Sunstar explodes, taking the Wily Star with him.

Other appearances
The Stardroids appeared in the CD database from Mega Man & Bass.

Mega Man (Archie Comics)
In issue 20, during his time travel fiasco, Mega Man meets Terra briefly before he is transported further in time. Dr. Light also briefly alludes to the Stardroids in Sonic the Hedgehog Issue 250 during the Worlds Collide crossover arc, when citing various instances where Mega Man had to save Wily from himself. At the end of the Ra Moon arc the dying supercomputer sends a final message to it's "children", meaning the Stardroids, to avenge it, as well as its failure to format the Earth for their benefit.

Mega Man Gigamix
The Stardroids are powerful space robots that attack Earth, destroying several robots in the process. Eventually, thanks to Mega Man, Proto Man, Duo, and the help from Dr. Wily, Dr. Light, Dr. Cossack and their robots, the Stardroids are destroyed one by one. However, Terra is able to activate Sunstar before he perishes. Sunstar and Mega Man battle in space, and although the fight appears to be hopeless, Mega Man doesn't give up as it's worth to protect the people from Earth, and Sunstar is defeated.

Other appearances
The Stardroids appear in short stories from the 1997 version of Mega Man Megamix and in a robot museum in the manga Rockman &amp; Forte.
