Using the Crystal Mirror, the Nightmare Creatures have found themselves in a world where humanity is at constant war with titanic beasts known as Kaiju. With the Mane Six, Spike, and Princess Luna on their tails, the greatest nightmare however, may reside in someone they can't control. And his name is...
