YMMV: A Future Of Friendship A History Of Hate

  • Complete Monster: Ruinate. He created Equestria to be a Crapsack World because that was his idea of paradise. When the other Sentiox took it away from him, he started destroying their worlds just to spite them, only to realize he enjoyed destruction, and went on a rampage, killing several other Sentiox in the process. And now that he's loose again, he plans on reducing Equestria back to its former state before picking up where he left off.
  • Hilarious in Hindsight: In this story, which began during Season 3, the Mane Six get Henshin Hero forms via the Elements of Harmony. Flashforward to the Season 4 finale, and they get something similar in canon via the Rainbow Power that replaces the Elements.
  • Moral Event Horizon: Looking at the above, you know Ruinate crossed it a long time ago. However, within the time frame of the story, his MEH is definitely rendering Twilight an Empty Shell and then mocking the other Mane Six about it.
