"Dang it, Jim, I'm an astronomer, not a doctor! I mean, I am a doctor, but not that kind of doctor. I have a doctorate, but it's not the same thing. You can't help people with a doctorate. You just sit there you're useless!"
―Dr. Doppler

Doctor Delbert Doppler is a self-described well-known astrophysicist belonging to a canine humanoid species. Doppler resides on planet Montressor and is a friend of Sarah Hawkins and her son Jim. He mostly acts like the typical, slightly eccentric, absent-minded professor who is not good at handling guns.

After Jim inherited a map device from a dying pirate containing the location of the lost Treasure Planet; Doppler funded an expedition to find it aboard the spaceship RLS Legacy. During the voyage he develops a romantic affection for the ship's captain Amelia; which appears to be of the same species of him. They would later marry each other and have four children.

Behind the scenesEdit

  • There was originally a scene mentioning that in their species it is the male that gives birth to the offspring; but this was deleted from the final version since the producers considered it controversial.
  • Dr. Doppler is based on two characters from Stevenson's Treasure Island: Squire Trelawney and Dr. Livesey. He was likely named after physicist Christian Doppler.
