She is the daughter of Lavender Lace and Fuchsia Blush (AKA Trixie’s two bandmates from Rainbow Rocks) ;3
Stardust is a pretty shy pony, who also has a really good singing voice. She can sing really well when she is along or with her friends, but she gets stage fright whenever she ends up having to preform in front of large groups of ponies. She hopes to have her own band someday, just like her parents.
She also has a fairly good knowledge of magic too, as she likes to use magic to help with the effects with her songs.
(The outfits on the right are her stage outft, her Rainbow Power design, her Gala Dress, and her Nightmare Night costume)
