Dr. Nefarious managed to reverse engineer the Elements of Harmony by harnessing the powers of both the Elements and Discord, naming them the 'Elements of Disharmony'. He has also cloned the Mane 6 with opposite personalities to wield them. Their names are Darklight Spark (Magic), Gray Dash (Defiance), Cruelshy (Rudeness), Greedily (Greed), Applejerk (Dishonesty), and Meanie Pie (Dishumor). Using these new clones to cause disharmony, Nefarious plans to become the new ruler of Equestia and turn everyone there into robot-ponies with his new Hippobliterator ("Hippo" translates to 'horse'), and turn Equestria into a robotic world. The Lodgers and the Mane 6 are called into action once again, but Twilight senses something about Nefarious' clones, who are showing signs of positive feelings, indicating that they are under the same scenario that she and her friends were in when Discord was last freed. Twilight soon realizes that the clones are not truly evil, and all they need is the power of friendship. But is this true?
