With Cybertrons supply of Energon nearly gone, the Autobots plan to take to the stars in search of a alternative energy source.

However, their archrivals, the villainous Decepticons, have the same idea and aren't about to let the Autobots get to any new energy source first.

Caught in a struggle, the Autobot ship known as "The Ark" and the Decepticon Warship "The Nemesis" are sent flying through a wormhole in space and crashland on a strange new world.

Kept in stasis for millions of years, a sudden blast of rainbow energy awakes and reprograms the Arks computer, Teletran One, causing it to give the Transformers new, organic forms.

Now Equestria has something else to worry about.
