Season three picks up where the movie leaves off, with the Autobots now in control of Cybertron once more, working to restore their homeworld and serving as peacemakers for worlds all across the galaxy. The Decepticons, meanwhile, are in exile on the ruined world of Chaar, led now by Galvatron, the rebuilt, upgraded version of Megatron recreated by Unicron. Interconnected episodes, running plot threads and small story arcs became more common in the series, including the return of Starscream (following his death in the movie) as a ghost, frequent battles between the giant Autobot and Decepticon cities of Metroplex and Trypticon and the threat to both sides posed by the alien Quintessons, introduced in the movie and revealed in the season's premiere miniseries "Five Faces of Darkness" to be the true creators of the Transformers.
