The AllSpark is gone. Megatron has been defeated and the Autobots have found a new world to call "home". But the Decepticon threat is not gone, however; Starscream, Megatron's second-in-command, has escaped and is amassing an army to take over Earth and destroy the Autobots.

I do not own any of these characters. They belong to Michael Bay, Paramount and Hasbro.
This story begins at the end of the 2007 movie of Transformers when Bumblebee finally speaks in his own voice. Arrival of the Allies is a prologue to Transformers: Revenge of the Fallen.
