While the Decepticon lair was being destroyed by the power of the malfunctioning space bridge, Megatron and Starscream are sucked into its portal which foils Megatron’s master plan of conquering Cybertron and defeating the Autobots. However, both Decepticons arrive in a colorful world which they have never seen before. Once they discover its inhabitants and the magic it contains, Megatron sees his ultimate chance to get his revenge on his worse enemies and conquer Cybertron.
Note: This happens after Transformers: Animated season 2 finale “A Bridge Too Close” and MLP: FIM season 7 finale “Shadow Play”.
