A crossover between Transformers and MLP:FiM.

Equestria is in danger once again. Chrysalis, the exiled Changeling queen, has made a deal with a powerful being beyond all imagination: Unicron, The Chaos-Bringer; a terrifying being capable of consuming entire planets.

This unprecedented threat to Equestria's safety causes the Mane 6 to seek out the help of new allies: Optimus Prime and the Autobots. But will their combined might and heroism be enough to stop Chrysalis's rampage of vengeance, or will Equestria and Earth both fall to the horrors of Unicron?

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.

The war of Cybertron wasn't just about Autobots and Decepticons, there were also civilians and rescue personnel. One such group was Rescue Bot Squadron Alpha 9, and their Wrecker bodyguard, who were charged with keeping a protoform nursery away from the fighting. To accomplish this, they hid on a planet with strange energy fields and gravitational anomalies to avoid detection. Unfortunately, the same energies caused them to crash into a mountain and remain in stasis for a thousand or so years. Eventually, the inhabitants built a city on top of that mountain, a city called Canterlot.

And now, the war is over, and the Bots are waking up.

Equestria was saved. The Transformers had arrived to their new home, a planet called Earth. The Autobots and Decepticons continue their war while the ponies of Equestria only have memories of the greatest heroes they ever knew.

But those memories….would soon turn into nightmares.

When an ancient evil returns to seek revenge on Megatron for betraying him, the Decepticons steal a precious element that the Autobots need. It’s a race to stop Megatron with Optimus Prime and his fellow Autobots as they all crash-land in the one place they swore never to return.

Megatron’s master plan will unfold. The end of days is coming. This is the rise of the Decepticons.

Experience the battle that changed their fates and decided the future of Equestria. When old enemies return on the helpless home of the equines, can even the mighty Autobots stop the great extinction that will fall upon the pony world?

The Legend will fall….in Equestria’s darkest hour.
