Amber
Amber is a dear friend of Crystal's and both of them are aliens working for the government of another planet, that have come to the Earth on a mission to investigate, but their paths will be brought with Shaggy and Scooby as they will fall for each other. Amber isn't from the same kind alien like Crystal, as she pretends as Crystal's dog in front of everyone and Scooby until he and the gang find out the truth!
