"One day, Lyra, the sun will set on my time here, and will rise with you as the new lord of chaos." "And everything in Equestria will all be mine?" "Everything." "Everything the light touches... But what about that shadowy place?" "That is 4chan. You must never go there, Lyra."
Discord can fly without flapping his wings (or even HAVING his wings in one scene,) appear as a reflection on the surface of a diamond (that's actually an ordinary NON-REFLECTIVE boulder,) turn the nicest pony into the world into a b*tch just by touching her, turn normal rain clouds into chocolate-milk-clouds made of cotton candy, and turn into both an image in a stained-glass window and a butterfly. I THINK he can find a way to fit on her couch.
... Oh, wait, I messed up.
Make that: "...can turn into THREE butterflies."
I love Discord. He's like Sheogorath, but 20% cooler.
