Two groups of robots who crashed to Earth in the distant past have returned to life and are making Earth—past and present—their battleground. These are the time-travel cartoon episodes that I spotted in the four original seasons (1984-1987) and in the Beast Wars episodes (1996-1999) in which time travel was commonplace. I haven’t seen the later series [Robots in Disguise (2000-2002), the Unicron Trilogy (2001-2006), the more recent animated series (2007-2010), and the webisodes (2010)].
They were called Autobots and Decepticons. But the brutal Decepticons were driven by a single goal: total domination. They set out to destroy the peace-loving Autobots, and a war between the forces of good and evil raged across Cybertron.
