The Invasion

Starscream joins no side during the war for Cybertron, instead staying neutral. He goes rogue on the Seekers, wanting no part of the war anymore. But without Energon, he is forced to follow the Autobots and Decepticons to Earth, struggling to survive on his own.
The Autobots try to convince him to join them. The Decepticons want to capture him.
But Starscream doesn't trust anyone.
