The Final Battle for Equestria [MLP]

Windy weather... Cold... Windigo in a word

Fear in the little hearts of ponies, unicorns and pegasi.

In one of the ruined castle's main halls, three villains stand: Cozy Glow, Chrysalis, and Lord Tirek. They have taken Grogar's power and channeled Celestia and Luna's magic and Discord's Chaos into the bell. They are now discussing their future plans:

Lord Tirek: The prisoners are securely locked in their cages! Now we can catch the rest... Pause. Did you look at the sky, Windigo?

Cozy Glow: Shivering from the cold, even with a blanket over her. I have no desire to catch anyone in this weather... She looked at her cold hands. Can we get rid of it with magic and warm up? She asks pitifully, but Chrysalis interrupts her.

Chrysalis: I don't think so. Smirk . Their appearance is very opportune for me)) Tirek interrupted.

Lord Tirek: You want to speak for us?!
Afterwards, Chrysalis and Tirek had disagreements, but after a while, Cozy interrupted them.

Cozy Glow: We should have dealt with Twilight and her friends first. Still shaking.

Lord Tirek: I thought you were cold and didn't want to catch anyone. There's a note of concern in his voice, which is very strange.

Cozy Glow: stubborn The need has disappeared points somewhere into the distance They are already here!

On the horizon appear: Twilight, Pinkie Pie, Fluttershy, Applejack, Rarity, Rainbow Dash and Spike.

Spike: Twilight , do you think they noticed us?

And then a portal appears before them, and Cozy Glow, Chrysalis, and Lord Tirek emerge from it, grinning. Afterward, a brief dialogue ensues between the two sides, and Cozy begins to fight first, followed by the others.

The Seven attempt to distract and steal the bell containing the others' magic back. They succeed, but the villains' plans quickly fall apart. Chrysalis tries to come up with a new plan on the fly, but it doesn't work. Other beings, including Luna, Celestia, and Discord, come to their aid, restoring their powers. But what to do with the trio of villains? They're wounded and weakened, but still dangerous.

The outcome is yours. What will you do with them?
