Long ago, in a realm similar to one we know well, Predators and Ungulates fought in a vicious war that ended with the Predators being banished to an interdimensional prison where they stewed for thousands of years. They managed to escape but were promptly sent back to their prison by the six champions of their homeworld.
Now being released from their prison for the third time, the last of the predators find themselves in a land somewhat similar to their own, yet different in many ways. United by their common predicament, the predators are ready to bring this world to its knees.
So whose going to stop them? Starlight Glimmer of course!
This may or may not be a good idea
