Meanwhile on the decepticon's new homeworld, The Fallen has finally awoken for the first time in Centuries.

He then sends Strika and her very own team to free Megatron and all of the Decepticons to find the All Spark fragments that were still all over earth for he can absorb its power. Jazz and Ironhide will be joining the team too as they find the All spark fragments that are widespread back on Planet Earth. The Constructicons, and Humans Villians return as well.
