The Reign of Starscream[]
Arriving in the Solar System in search for the AllSpark, Starscream's forces put the Nemesis down on Mars and set up a camp. Some went ahead to Earth to search for the AllSpark, but a few stayed behind.
When Starscream returned after losing the AllSpark, a group of Autobots had a brief skirmish with them, but was quickly subdued and the Decepticons used a space bridge to return to Cybertron.
Still later, the treacherous Dreadwing returned through the space bridge, but remained alive only long enough to be killed by Starscream, who promptly set out for Earth once more.
Alliance #2[]
Soon after, Soundwave arrived upon the debris field and examined the Nemesis before similarly heading for Earth to find Starscream.
