Dr. Doppler

Dr. Delbert Doppler is a character from Disney's 2002 movie Treasure Planet. He is an alien with the appearance of being some kind of dog/human hybrid, and a notable and well-off astronomist. He was the deuteragonist as well. Delbert Doppler is a long time friend of Sarah Hawkins, Jim’s mother, and after the BenBow Inn burnt to the ground he housed her and Jim without hesitation, saying they could stay as long as they needed to. When finding out about the maps potential, Doppler immediately agreed to go searching for the treasure with Jim, convincing Sarah it was a good idea. He pointed out to her wisely that he wasn't just doing it because he wanted to go; a few character-building months in space might help with Jim's increasingly rebellious nature.
