Julie is the owner of Andrew's Art Gallery.
She has red hair in a ponytail.
She was willing to do a lot and take risks for her brother.
Scooby-Doo! (DC Comics)
Julie wanted to help her brother Ryan get a mysterious story for his paper. She had a series of monster painting done, with the monster collecting a series of stolen items as they went on. (Actually nothing was stolen; Ryan just hid the items within the stores they came from). She replaced paintings when the gang wasn't looking. (Fright Ride)
- She owns "Andrew's Art Gallery", so her full name may be Julie Andrew (almost the same as the actress), but there are too many other possibilities to make it official.
