TWILIGHT SPARKLE
Age: I don't know what it is relative to this world's time frame.
Monster parent: Erm…Unicorns?
Killer style: I came in with a pleated skirt and sleeveless jumper with my cutie mark on them, a bit darker in theme than my Canterlot High clothes but otherwise the same.
Freaky flaw: I can be way too uptight and focus on a single issue rather than the big picture…but I'm having a hard time finding the big picture in this place!
Pet: An owl named Owlowicious. He caught one of my papers after it blew out one night and since it was cold I let him stay.
Favorite activity: Studying, studying, and more studying! Magic, science, nature; anything to increase my knowledge! Studying with friends is even better!
Biggest pet peeve: Not understanding something. It's a maddening feeling.
Favorite school subject: None! I haven't been here for long and it's really awkward staying uncover in a place so unlike Equestria or even Canterlot High, so I look like a complete ignoramus when asked the simplest questions! I guess sticking around will mean I'll learn though…
Least favorite school subject: Physical education—physical deaducation? Oh for the love of Celestia…They really push you hard at gym here. No wonder everypony's so thin!
Favorite colors: Purple and magenta.
Favorite food: Hayburgers and ketchup! Of course, they don't have hayburgers here…
BMFFs: What does this even mean? Best monster friends forever? Erm, I guess Clawdeen Wolf and Frankie Stein have been very accommodating.
Monster fun fact: I'm not a monster and this mission at Monster High is getting crazier by the minute! Somepony please get me out of here!

Twilight Sparkle has a new mission from a most unusual source: herself from an alternative universe, one that is waging war against a mysterious and terrible new enemy. To help her alternative self Twilight needs to recover a new power source for her, namely the power to make her muscles really big, and only in a far-off place called Monster High can she find it. Twilight's survived Canterlot High though; how hard could it be to make new friends at a campus full of werewolves, vampires, and zombies that also want this power? And what happens when Twilight starts falling in love with one of them? And can Twilight control the monstrous transforming she begins undergoing?
