Exiles

Ransack led Optimus Prime, Bumblebee, Jazz, Silverbolt, and Perceptor to Delta, where they met Override and learned of the many resource shortages that plagued Velocitronian culture. However, they had arrived just in time for the Speedia race, which took place in the center of Delta. The generally favorable reception that they recieved allowed Optimus to land the Ark there. However, when Ransack instigated a war, the Autobots fled at Override's request. Delta would later be used as a temporary base of operations for both the Star Seekers and the Decepticons.
