Inferno finds a second Golden Disc, marked with alien runes. Megatron and Optimus supposedly agree to a truce, and Tarantulas is determined to get off Earth.

The Vok unleash a monstrous weapon, an artificial moon, intending to destroy Earth and all Maximals and Predacons on it. Using a stasis pod equipped with transwarp cells, Optimus flies to the moon to destroy it, but Megatron deviously seals the pod shut, causing Optimus to be destroyed along with the moon.
