Dr. Proctor is a character of the day who appeared in A Chansey Operation (EP047). He is a doctor for humans, who was forced to treat injured Pokémon after an accident involving Team Rocket and a truck load of stolen Pokémon.

Dr. Proctor is a womanizer; he made advances on Misty, Jessie, and Nurse Joy. However, these attempts failed on Misty and Nurse Joy, but not on Jessie, who fell for him immediately.

Proctor also appeared to be very lazy, but mostly, he had very little confidence that he could treat Pokémon, as he had no experience in the matter. He didn't want to open up his hospital to treat any of the injured Pokémon until Ash, his friends, and Nurse Joy convinced him to. However, once he was engaged, he became a skilled and competent physician, treating his patients with confidence and compassion. He also proved to be a formidable fighter, using his medical equipment as weapons to help foil Team Rocket's attempt to steal all of the injured Pokémon again.
