An unannounced rip in the reverse realm sweeps up Princess Celestia and takes her captive. Unable to enter the reverse side of Equestria themselves, the Mane Six must make copies to venture in for them. Copies whom have complete opposite, or 'reverse,' personalities and attitudes of the original, and with extensive military training and cold hearts... and they don't have a way to monitor them. Will the bloodthirsty mercenaries carry out their mission and rescue Celestia? Will they get figured out and put to death? What will they do in the chaotic, uncivilized, all-for-one wasteland of Reverse Equestria, where no 'harmony' was ever held?
