Gotta say, that's pretty damn awesome. And for some reason, this little thought popped into my head when I saw her demon-dragon form, as quoted from a book I once read.



Sunset: You continue to pester me like a flea biting at my flesh! But that isss all you are, Twilight Sparkle! A flea! A FLEA!!



*Insert horrifying transformation sequence as her body bends and twists in angles that should have broken them, wings sprouting from her back as her tail and mane erupt into flame. Sunset's eyes burn with such hatred that Twilight half-expected to drop dead just from the rage within. Standing on her hind legs, the crimson behemoth stared down at her enemy, her long, snakelike tongue darting about like a frenzied whip.*



Sunset: It isss time you learned, flea, what a dragon is TRULY capable of!



*Sunset Shimmer inhaled...then exhaled an inferno.*
