I was seeing the old G1 episode"the five faces of darkness"where Galvy takes over the decepticons. They are in great need of energon. Is it because they lost the battle with Unicron or earth or Cybertron or there arent'any more seekers. The seekers were the ones that were programmed or trained to search for enegron sources.
Its because they lost the battle with Unicron and are stranded on a rocky little backwater planet without a supply of energon. The seekers only seek in the new movie continuity.
