She is a main character in part of episode 5 and all of episode 6, but those are the only two episodes she shows up. Also, at the very episode 6, she has one line where she is an adult, but if you don't think you can do that it's completely fine! Still audition for the kid version, please :)

She is about 8 years old, and also she turns evil so you will have to make her sound evil for most of it. (When she is evil, her lines are called Pony of Destruction/Kaia)

Note:

She will be a minor character in the spinoff
