In the year of 2015, Humanity has been greeted upon by sentient ponies from their dying world as they only wanted to come in peace and would like to coexist. Although, their peace was short lived when Princess Celestia suddenly changed as she converted humans into newfoals in order to "save mankind" from their own extinction. At that point, a new war has started between Humanity & the pony rebels against Celestia and her new empire. Six long years after the war, everyone's lives grew worse when two more portals open up. Each of them were separate universes of Earth that's filled with heroes and villains. Worse, the remaining survivors were fleeing away to shelter from the infections of powerful super zombies. Now a group of resistance alliance team must join forces in order to end this zombie and conversion nightmare before all three worlds would surely fall.
