Mary Sue Perfect

Mary Sue Perfect is one of the instructors at the Elemental Organization. She teaches transformation, the art of bonding with a guardian animal, literally becoming one with it. During transformation, an elementalist's soul will merge with the body of the guardian animal. (Perfect's guardian animal is a unicorn named Little Miss Happy.) Many characters do not like Mary Sue Perfect, finding her annoyingly perky. Perfect is also an Earth elementalist.

(Spoilers ahead)

Mary sue Perfect was killed by Amoria in book three. An Umbroc takes her form. However, it is implied that she comes back to life when Ebony sends Amoria back in time, reversing her actions.
