I always consider Diamond Tiara as less a spoiled brat and more a young, pint-sized, female pony Palpatine, who's going to grow up to become a potential evil overlord or super villainess, gunning for World domination. She shares a lot of similarities with young Palpatine, too, with the exception of Force powers, an abusive parent and a Sith Lord mentor like Darth Plagueis.



(Well, that just gave me an idea for a FIM story...)



She would definitely want to become an Alicorn, though, and I suspect it'll involve a truly diabolic scheme...
