Grogar’s masterplan now come to fruition. With Soundwave and the Decepticons by his side, along with his powerful magic, he will be unstoppable. But to make things even worse, they manage to corrupt Princesses Celestia, Luna, Cadence, and unfortunately Twilight Sparkle as well. With that, Equestria has now become a barren wasteland. With death and destruction being everywhere, it would appear as if Grogar has won at last. But his endgame will come short. A new brand of heros crash-land on Equestria and discover where the Decepticons have been all along. Optimus Prime and the Autobots must find a way to defeat not only Soundwave and his army, but a new foe they have never seen. Will Optimus be able to overcome the mighty Grogar in ALL of his power or fall under his tyrannical hooves?
