YMMV / The Conversion Bureau: Worlds Where It Wouldn't Work

• Nightmare Fuel:
  • The SCP section of one of the world Suggestion chapters has the entire pony race being exterminated and Xlestia being put on a drug induced lobotomy, while the Foundation experiments on her. If that was not enough, the one researcher who tried to show her a hint of humanity was "removed from the assignment for potential contamination".
  • Bruce Banner willingly takes the potion to try to destroy the Hulk, seeing as how it "removes" negative emotions. The good news is that it works and removes all the negative emotions from Bruce. The bad news? Said negative emotions then coalesce into a Hulk completely free of Bruce Banner's influence.
• Rooting for the Empire: The readers want Xlestia to destroy the "Fall of Equestria" world.
• The Woobie: All of Equestria could be this, seeing as how they are a prosperous land that repeatedly gets dragged down by Xlestia's schemes.
