The Decepticons come to Equestria to obtain all their resources. With the Autobots stuck on Earth, and magic having little effect on Transformers, the Decepticons have little to oppose them. Starscream is pulled out to a different light from seeing the planet and starts to remember how he used to be before the Cybertronian war and little more 'organic' insight of the planet.

Rainbow Dash however isn't going to let her planet go without a fight and she has back up from an unlikely source.

Applebloom just wanted to spend a day with her friends, crusading for her cutie mark. Instead, she found something even deeper and more troubling about herself. Turns out she's not even a member of the Apple Family by blood. In fact, she's not even truly native to Equestria! She's an alien! An alien robot no less!

Now Applebloom will have to deal with the reality of her origins and try to cope with them and her newfound abilities as she moves towards her future; a future that just might never come to be if her new foes have anything to say about it. Decepticons are, after all, a monstrous cabal.

Now, it's up to Applebloom to light Equestria's darkest hour.
