The Final Battle for Equestria [MLP]

Windy weather... Cold... Windigos, in a word.

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

In a ruined castle, in one of the main halls, stand three villains: Cozy Glow, Chrysalis, and Lord Tirek; who have taken Grogar's own power and trapped the magic of Celestia, Luna, and Discord's Chaos in the bell. Right now, they are discussing their further plans:

Lord Tirek: The prisoners are securely locked in cages! Now we can catch the rest... Pause. Looked at the sky Windigos?

Cozy Glow: Shivering from the cold, even though she is wrapped in a little blanket I have no desire to catch anyone in this weather... 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 we should. Smirk Their appearance is very convenient for me)) Tirek interrupted

Lord Tirek: You mean for US?!
After that, Chrysalis and Tirek had a disagreement, but after a while, Cozy interrupts them

Cozy Glow: First, we should deal with Twilight and her friends... Still shivering

Lord Tirek: I thought you were frozen and that's why you didn't want to catch anyone. A hint of concern is felt in his voice, which is very strange

Cozy Glow: stubbornly The need has vanished points somewhere in the distance They are already here!

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

Spike: To Twilight Do you think they noticed us?..

And immediately a portal appears before them, and Cozy Glow, Chrysalis, and Lord Tirek step out of it, smirking. A short dialogue takes place between the two sides, and Cozy is the first to start fighting, followed by the others

The seven try to distract them and steal the bell with the others' magic back. They succeed, the villains' plans quickly crumble; Chrysalis tries to come up with a new plan on the fly, but it doesn't work. Other creatures come to the rescue, along with Luna, Celestia, and Discord, and their powers are returned to them. But what to do with the trio of villains? They are wounded and weakened, but still dangerous

The outcome is up to you. What will you do with them?
