The Beast Wars were over, the Maximals emerged victorious. But upon their return to Cybertron and their proper time everything changed. Waking up without any memory of how they got there, the Maximals find themselves on a planet overrun with mindless Vehicon drones and ruled over by the enemy they thought vanquished: Megatron.
The sequel to Beast Wars went rather metaphysical on people and brought along some very confusing storylines along with very dark and sometimes less-than-brilliant computer animation. Generally regarded as a let-down after the brilliant Beast Wars, the series nevertheless had some interesting points to it. And a few interesting toys, too.
