Dr. Doctor is the brother of the Crazy Cat Lady and uncle to Donna. He is a doctor, but was a carpenter when he was younger. When Alexis was turned into an adult by Zane's dark magic, Dr. Doctor stayed in Phoenix Drop to figure out what was wrong with Alexis.
As of season 3, his current status is unknown.
Dr. Doctor has black and grey hair and bright blue eyes. He wears a black tuxedo with a blue tie and gold fasteners.
Let's just say he's sort of like his sister (Crazy Cat Lady), but not cat-crazy and much more serious. he stayed behind in Phoenix Drop to help Alexis, but if it was his sister instead of him, the crazy cat lady would have just drowned Alexis in cat memes.
-He might be a reference to Aphmau's old survival series, Headren War(Hexxit) as there was a character named Cpt.Captain.
