The Human Mane 6 get turned into sirens

This is where the Human Mane 6 get turned into sirens in The Revenge of the Overlord.

Human Twilight Sparkle: What do you want, Overlord.

The Overlord: A truce.

Human Rarity: Hmph. You wish.

The Overlord: But no ordinary truce, but a truce where you will accept being my humble siren singers.

Human Twilight: What do we get in return?

The Overlord: I set your steam engine boyfriends, your two new siren friends, Cyrus Borg and P.I.X.E.L free.

Human Applejack: And if we refuse?

The Overlord: Then none of that happens.

Human Rainbow Dash: Well, nice try.

[Sonata Dusk, who is still under the Overlord's hypnosis, clicks her fingers and General Cryptor zaps them with a prod]

Human Mane 6: [screaming]

Human Twilight: Okay! Okay! We accept!

[General Cryptor stops zapping them and the girls take a moment to breath]

The Overlord: Excellent. [chuckles evilly] Sonata, put their pendants on their necks.

Sonata: Yes, master. [picks up the pendants and places them on the girls necks]

[Adagio and Aria look on in horror]

Adagio Dazzle: Sonata, how could you do this?

The Overlord: Quiet, you!

[Adagio zips it]

The Overlord: She may not be my servant, she's under my total control now.

Sunset Shimmer: Your army will never get the chance. The Ninja and Lloyd will keep them from ever reaching us.
