[Contains S6 Finale spoilers, just in case.]

Discord knew that running a distraction against the changelings wouldn't have gone easily, especially when he was the only one getting their attention. He never thought that it would go this badly though, isolated, faced with dozens of the bugs twisting the image of his best friend, with no way out. That they would use Fluttershy in such a way against him though...They shouldn't have given the lord of chaos a new motive to stand against them.

They're going to win, even he can't deny that. But he's going to take some of them with him.

Not part of the Quickverse, just a little idea that came to me in bed after rewatching the finale and was written up in a few hours.
Rated M for changelings being manhandled in ways they don't survive.
Update: Huh, made it to the popular stories again? I know that doesn't sound like much but for a small time writer like me it's a major achievement. Thank you all!
