|This needs a stretch.|
In dog form, Amber had a black nose and eyes, golden-brown fur, and also wore a red bandana around her neck; the bandana hid her peace sign medallion that, when activated, transformed her from a dog to an alien. In alien form Amber was bipedal (walked on two legs), was blue-green from her back to her arms and legs, and had a sky-blue belly. Her head was like a beak, and she had piercing yellow eyes. Her feet had two toes with a spur in the back and her hands had three fingers.
Amber turned out to be a very affectionate character later on in the movie. Seeing Scooby at first glance, she huffed and turned her head unimpressed. She continued playing hard to get up until Scooby Doo made himself look good and offers her a bunch of flowers where she then licks his cheek in flattery. At this point forward, Amber continues to show affection towards Scooby Doo.
Powers and abilities
She had the ability to transform back and forth from an alien to a dog by using her pendant. She was also very strong, and could talk, which she revealed to the gang before leaving.
Scooby-Doo and the Alien Invaders
Amber wasn't initially interested in Scooby, but he continually tried to impress her. When he made himself look good and he brought her flowers, she gave him a lick on the cheek and he rejoiced and brought her a whole rose bush. Scooby didn't care when he found out she was a government-trained dog; he still loved her. She convinced him to go back over the fence with her and Crystal by using her charm on him. When he agreed, she gave him a lick on the cheek. He then smiled and laughed. When the MP's came he was willing to protect her despite his fears and later saved them from the SALF crew. Amber revealed that she could talk and did it without the "R"s like Scooby does sometimes. Before leaving, she told Scooby she would never forget him and kissed him on the lips. She then left in her spaceship with Crystal.
Amber: Good-bye Scooby, I'll never forget you.
