Inner Demons/YMMV


 * Complete Monster: Queen!Twilight quickly proves how much she fits this trope. Her only redeeming trait is that she still seems to love her brother.
 * Which actually makes her worse, really.
 * Likewise,  embraces her Face Heel Turn, quickly becoming a sadistic bully who takes great pleasure in trying to kill the other Elements of Harmony.
 * Evil Is Sexy: Rarity's birthday gift to Twilight was teaching her how to highlight her natural good looks. Then she turns evil, and really gets into keeping up her looks.
 * , post Face Heel Turn, also qualifies. She comments on how she's just as beautiful as Rarity, and starts flaunting her looks even more than Queen!Twilight does.
 * Les Yay: As is popular in fanon, Rainbow Dash and Pinkie Pie's subtextual Les Yay is upped to them having crushes on each other.
 * As of chapter 16, this has been bumped up to an Official Couple.
 * Moral Event Horizon: Queen!Twilight crosses it big time with her "coming out party". First there's the Sadistic Choice listed on the main page, which is quickly followed by  in an attempt to kill them.
 * crosses it during her attack on Ponyville. First, she drives Rainbow Dash to the point of exhaustion with a race she had little chance of winning, then leaves her unconscious for her troops to finish off. And while that's not too bad, it's followed by her capturing Pinkie Pie, locking her in the CMC clubhouse, and setting it on fire when the other heroes show up to save her, basically forcing them to watch her die.
 * Shocking Swerve:  and  's Face Heel Turns. Some of the last characters you'd expect it from.
 * Squick: Queen!Twilight acting out her incestuous feelings towards Shining Armor.
