[As transcripted from a Nightmare Rarity voice sample source video (see link in credits)]

It's true - your powers defeated me before, little ponies. But what will you do now that I've taken one of you? Without all of you, your Elements of Harmony are powerless.

You ponies are tense, aren't you? Remember all those nightmare forces you destroyed with your Elements of Harmony when Luna was around? Well, guess what - you didn't do a super job after all! They now control your friend!

Me, I suppose? Rarity is GONE! Do I need to make a diagram or something with pictures so that you can understand?

Spike, ENOUGH!

Luna, Luna, Luna - you had it all. How foolish you were to give up your power! And for what - these weaklings? Ha! If you had taken my offer and became Nightmare Moon once more, your precious ponies would be spared. You've done this to them, Luna, and they will never forgive you.

They say that now, but who can forgive some pony who destroyed lives? It doesn't matter what you say. I'm taking Ponyville, and you will be powerless against it.

TAKE THEM DOWN! [repeated 5x in the song]

Take them to the dungeon; they're boring me.

There will be NO mistakes; we must strike while those meddling ponies are locked away.

Oh, my dear Larry - my dear, simple, unamused Larry - I picked this pony vessel for a reason: to render the Elements of Harmony POWERLESS! I chose Rarity specifically; she had - shall we say, self-esteem issues? I needed a being that was... pliable.

Rarity was so eager to help - so generous with her gifts, but she had a deep, dark secret. I was sure she would cave.

Well, sometimes, a little force is necessary... for now, leave them in the dungeon. Or we could always lock them up and throw away the key! [evil laughter]
