I think mine, for online stuff, was a tiny childlike girl who's name I cannot remember for the life of me. She came from the moon kingdom (not like, Sailor Moon's moon kingdom, but a whole new one I came up with when I was a kid) and had some kind of magic crystal thing she talked to a lot for guidance. She was a psionic who delighted in pulling really childish pranks and who just wanted a big brother.

I know she had blue hair, but that's about all of her that I remember. XD
