Mary-Jane

Mary Jane is a college student and Shaggy Rogers's love interest whom she met on a plane heading for Spooky Island. She is allergic to dogs, but tolerates it for the sake of Shaggy and Scooby-Doo. She was at one point possessed by The Theme-Island Demon until her protoplasm was freed and returned to her body.
==Physical appearance==
Mary Jane is a Caucasian female with a light tan, with long, curly blonde hair, and brown eyes. When she met Shaggy, she wore an orange shirt and a long denim skirt. Prior to the Demons' attack, she had switched to a sparkly pink, long-sleeved top with a notably short hem, exposing her belly and back, and brown shorts. After being possessed, the demon in control of her body switched her outfit to a red bikini top covered by a lace yellow vest, with the tails parting to her sides, once again exposing her midriff, and jean-shorts.
==Personality==
She is kind-hearted, and has a secret fondness for Scooby S Snacks. She and Shaggy instantly hit it off when they met. After being freed, she accepted Scooby, despite her allergies.
==History==
===Scooby-Doo: The Movie===
At some point, she was captured and her protoplasm was taken out and a demon possessed her and took control of her body.
