Twilight Sparkle: “So, let me get this straight. Not only did you send my FRIENDS these extremely offensive and threatening letters, you did so with the explicit purpose of making me angry. Then, since I apparently wasn’t angry ENOUGH, you proceed to act upon those threats. Now, Applejack will be bedridden for a month, Fluttershy has yet to leave the safety of her cottage, Rainbow Dash might never be able to show her face in Cloudsdale again, Rarity’s fashion career will never recover, and Pinkie Pie straight up refuses to talk about what happened. All because you thought my friendship with them was holding me back.”

Minion: We’re gonna rip ya apart inta a bunch o’ pieces, an’ then we’re gonna take those pieces, and rip them apart inta even more pieces!  
Twilight: (cue picture) I’m waiting.

When a character like Twilight makes a face like that, that’s the time where you should run.

She noticed you were dog earing pages.

I wouldn’t say super saiyan since her hair hasn’t changed but she does have that visual of charging up her ki like in dragonball.
