Nightmare Moon quotes from My Little Pony: Friendship is Magic

[to Twilight] I am the ruler of all of Equestria. Do you think I can't deal with timberwolves?

Oh, my beloved subjects. It’s been so long since I’ve seen your precious little sun-loving faces.

Rainbow Dash

What did you do with our Princess?!?

Applejack

Whoa there, Nelly!

Why, am I not royal enough for you? Don’t you know who I am?

Ooh, ooh! More guessing games! Um...Hokey Smokes! How about...Queen Meanie? No...Black Snooty! Black Snooty!

Does my crown no longer count, now that I have been imprisoned for a thousand years? Did you not recall the legend? Did you not see the signs?

Twilight

I did! And I know who you are, you're the Mare in the Moon: Nightmare Moon!

Well well well, a pony who remembers me. Then you also know why I'm here...

Twilight

You're here to... to... [gulps]

Remember this day little ponies, for it was your last. From this moment forth...the night...will last... forever! [laughs evilly]

Twilight

You think you can destroy the Elements of Harmony just like that? Well, you’re wrong—because the spirits of the Elements of Harmony are right here!

What? [Gaunson: we’ll looks like you lost. Do your part twilight

Twilight

Applejack, who reassured me when I was in doubt, represents the spirit of...Honesty! Fluttershy, who tamed the manticore with her compassion, represents the spirit of...Kindness! Pinkie Pie, who banished fear by giggling in the face of danger, represents the spirit of...Laughter! Rarity, who calmed a sorrowful serpent with a meaningful gift, represents the spirit of...Generosity! And Rainbow Dash, who could not abandon her friends for her own heart’s desire, represents the spirit of...Loyalty! The spirits of these five ponies got us through every challenge you threw at us!

You still don’t have the sixth Element! The spark didn’t work!

Twilight

But it did. A different kind of spark. [To the others] I felt it the very moment I realized how happy I was to hear you, to see you, how much I cared about you. The spark ignited inside me, when I realized that you all...are my friends!

Twilight

You see, Nightmare Moon, when those Elements are ignited by the spark, that resides in the heart of us all, it creates the sixth Element: The Element of...Magic!
