ARMY OF CHANGELINGS

“I will nail your broken body to the walls of the castle so you may watch your hive die.”

WHAT NOW WENCH

Still betting on Chrysalis and the changelings.

And no one heard of Chrysalis again.

And then Nightmare beat down Chrysalis, but before she could finish the bug off, Celestia recovered and summoned Discord (who has since made a Heel Face Turn) to intervene.
 
(No points for guessing what I’m referencing.)

NMM: “I’m going to enjoy hurting you.”
 
Chryssy: “I..I have an army!
 
NMM: “Call them then. It should make things more…amusing. You have chosen the path of PAIN!

You invade my kingdom, threaten my subjects and harm my sister? Let me show you why Nightmare Moon was once feared by ALL!

Incoming 1000 Troop Changeling Army in 3, 2, 1.

“I’m the only one allowed to beat on my sister. Now, it looks like you just wasted your entire magical reserves doing just that. That really is a shame, isn’t it?”
 
“Uh… Uncle?”

Game…Set…Match!

@Lium, And then Nightmare Moon (now under the control of Luna) utterly trounced Chrysalis and then checked on her sister.

“This isn’t even my final form”

And then Nightmare Moon beatdown Chrysalis, and took over Equestria as their supreme leader. And it was glorious.

Shit. Just. Got. Real.
