LOL, The original series JAV. It first started millions of years before 1985, then they crashed on earth and went into a type of hibernation, they awoke in 1985 (IIRC, could be a year of two off), during their hibernation the series of Beast wars was taking place as the decepticons and maximals were dogfighting in space, they traveled back in time to when the Arc was already buried inside a volcano, at the end of the series they made it back to the present time (unknown year to me). Confused yet?
