She is a bat pony alicorn, who is dedicated to performing the most powerful spells, as she wants and tries to become a very powerful pony.
Although she usually looks like a slimy and very malicious witch, however, she has a very humble and sweet heart that just lacks a little love from a special pony. She hopes that she is able to find love one day and help do magic together with her special somepony.
She has big dark circles under her eyes, due to the fact that she spends all night studying spells and not getting enough sleep. Because her magic is not as strong as others, she uses her staff to help direct her magic more precisely, and stores magic reserves in her gems.
