Buster is aghast at his father, who senses hostility from the Autobots and attempts to escape, only to suffer a heart-attack when Jazz tries to stop him with a flame-thrower. Ratchet takes him to hospital while the Autobots desperately plan their defence. Megatron tests his new strength by taking a heavy barrage from the US troops without damage. Meanwhile, Huffer tells Optimus of something that occurred while they were still dormant - Shockwave had landed on Earth in the Savage Land. The Ark sent Grimlock, Slag, Snarl, Sludge and Swoop to investigate. The fates of all six are unknown.
