This is how Twilight's Sacrifice goes in My Little Pony: Equestria Girls: Revenge of the Overlord.
[The ponies and Autobots plot their next move]
Twilight Sparkle: This is the last time you try to hurt us!
[Twilight shoots beams of magic at the Overlord, then uses her levitation]
The Overlord: What are you doing?! Let me go you fool!
[The others watch as she floats up]
Rarity (EG): No, Twilight! No!
Sunset Shimmer: We have to get out of here. Now.
[They run off as Twilight continues to float up. Optimus and Sunset look back at Twilight as she is slowly torn apart]
Optimus Prime: Be safe in the Well of Allsparks, Twilight.
Sunset Shimmer: Good luck with your afterlife.
[A few tears shred from their eyes. From a building, Flash Sentry watches as Twilight makes the ultimate sacrifice]
