Crystal is the main female protagonist of Scooby-Doo and the Alien Invaders. She is a government agent from another planet posing as an Earth government agent/photographer, and Shaggy Rogers's love interest. She was using cool lingo that Shaggy could appreciate; she also dressed in a 70's hippy style.


Crystal has long chest-length black hair and brown eyes and wears an orange shirt and headband. She also wears blue bell bottoms, a peace sign necklace, and a camera around her neck. In her alien form, she has light blue skin and has the same peach sign necklace from her human form.

Powers and Abilities

Crystal and Amber both had the ability to change their appearance using what looked like a pendent, but was actually an image-changing device. The device also had a picture of their true form on it.


Crystal and her golden retriever, Amber, found Shaggy Rogers and Scooby-Doo in the desert. She shared water and helped them return to the town. Her jeep was full of the tools of her trade. Crystal and Amber was helped defeat evil scientists left Earth for their home planet after the mystery of the alien invaders had been solved. Shaggy and Scooby were extremely sad and heartbroken when Crystal and Amber departed back to their home planet.
