The Dresden Fillies/YMMV
- Complete Monster: Trixie becomes this as soon as she lets herself get possessed by Nightmare Moon.
- Crosses the Line Twice: In-universe example: Luna's reaction to Harry using the Elements of Harmony to supercharge a fire spell? Laughter to the point of tears.
- Iron Woobie: Twilight Sparkle and Pinkie Pie.
- Moral Event Horizon: Harry sees the foalnapping of Spike as this. It makes him so angry he almost kills the defenseless kidnapper. And when the Mane Six try saving him from himself, he turns on them.
- Oh Crap: Readers, tell me you didn't have this reaction at the end of Chapter 10.
