On a seemingly regular day in Equestria, something out of this world decides to come for a "visit"... unwelcomed, of course. Lord Boros, The Dominator of The Universe, and the Leader of The Dark Matter Theives, look to destroy the planet as usual just like any other.

On the other side, we have Equestria's regular villains, already planning to conquer Equestria on their own. How will the two forces act once they inevitably meet? Will they team up, or rival each other in an all out war of who will control the planet?
