Pony Megathread

[Obliviator27]

Going to have to go with Discord.

Nightmare Moon was stopped by the power of the Elements, wielded by the Mane Six/
Chrysalis targeted Canterlot, not Ponyville. Maybe she planned to attack Ponyville later, but my point stands.

Discord managed to trick and corrupt the Mane Six, rendering the Elements useless. Sure, he may not have posed a physical threat to the inhabitants, but definitely a mental one. Save Pinkie, of course, who enjoyed the chocolate rain.
