This story is a sequel to Transformers Prime: A Brave New World

It has been three years since the Autobots have left Equestria. In that time, tragedy struck the peaceful planet. The Decepticons returned, capturing Canterlot and Princess Celestia. In the ensuing chaos, Cadence and Twilight transformed Ponyville into a fortress, shielded from orbital bombardment by Discord. With Luna missing, can Optimus and his expanded army of Autobots liberate Celestia, Equestria, and finally free the planet?

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.

*Begins shortly after the events of "Princess Twilight Sparkle"*

After the events of Transformers: Age of Extinction, Optimus Prime takes to the stars to confront the great creators of his very race. Among these planets he had passed, he noticed that many of them were seeded like Earth was. One of these planets was Equestria, and the Ponies there find out that there are more to their own lives, and themselves, than they could ever have known.

The Sex and gore tags are there mainly for the dialogue done, and IF said events even happen.

The fate of Equestria lies in Twilight Sparkle's hooves when two warring clans of ancient, alien robots arrive on the planet in search of a long lost relic.

After the Decepticons discover energon on a distant planet, Optimus Prime and the Autobots arrive in Ponyville, quickly attracting the crown's attention. Now it is up to the Autobots and their newfound friends to protect Equestria from the Decepticons. However, as they continue their battle, Optimus and the others discover the bonds between their worlds run deeper than either believed. Can the Autobots and their newfound companions end their centuries long conflict and spare Equestria from the violence that destroyed Cybertron?
