This is how Enter Midnight (Black Twilight) goes in My Little Pony: Equestria Girls: Rainbow Rocks.
[We see Sunset and Human Flash Sentry in the main foyer]
Sunset Shimmer: Hi. Are you the new guy we're supposed to show around?
[Midnight, disguised as a human, steps out of the shadows]
Midnight: [disguising his voice] I am. My name is Midnight.
Flash Sentry (EG): Nice to meet you, Midnight.
Sunset Shimmer: Canterlot High is a great school, my friend. Trust us. You're really gonna love it here.
Midnight: [disguising his voice] Oh, yes. I really sense that there's something... how shall I say magical about this place.
[Human Flash Sentry and Sunset Shimmer later lead Midnight through a corridor]
Flash Sentry (EG): Over there is the science lab.
Sunset Shimmer: Computer lab is that way. [spies a poster for the showcase] Oh and also, we're having a bit musical showcase this weekend. The whole school is pretty much rallying around it.
Midnight: [gasps, disguising his voice] A musical showcase?
Flash Sentry (EG): We're sure that since you're new...
Sunset Shimmer: Principle Celestia would be happy to sign you up if you're interested.
Midnight: [disguising his voice] I have been known to sing from time to time.
Flash Sentry (EG): Seriously?
Sunset Shimmer: [notices Midnight's gem] Whoa. That's pretty. Where did you...? [reaches for it]
Midnight: [grabs her wrist then lets go, disguising his voice] Sorry. This gem means an awful lot to me. I'd just hate for anything to happen to it.
Flash Sentry (EG): Oh. Okay.
Sunset Shimmer: Well, see you soon.
Midnight: [leaves, disguising his voice] See ya.
[Midnight secretly smirks]
Midnight: [to himself] This gem will also help provide me the needs I need to destroy Princess Twilight Sparkle once and for all.
Flash Sentry (EG): What was that?
Sunset Shimmer: What did you say?
Midnight: [disguising his voice] Nothing.
Flash Sentry (EG): What's with him?
Sunset Shimmer: Let's follow him.
[They follow Midnight to a room and watch as he takes out a communicator and activates the communicator and places it on the floor and a hologram of Thunderwing appears. Midnight bows before him]
Midnight: I have just the very thing I need to defeat Princess Twilight in my reach.
Thunderwing: What is it?
Midnight: Magic from her realm has found its way to this realm.
Midnight: Soon Princess Twilight Sparkle will cease to exist forever.
Thunderwing: You have been well trained. They will be no match for you.
