Millions of years ago, a great machine crashed on the planet Equus. Now, the newly crowned Princess Twilight Sparkle and her friends meet five titans from beyond the stars that ponykind sees each night. These "Autobots" fled their home in search of a new world to call home. Followed by their sworn enemies, the Decepticons, the Autobots will fight to protect their new home, with the aid of the six young mares who have defended their world from evil many times already. The 'Cons are going to need more bots.
