Dr. Katz is the main character from Dr. Katz, Professional Therapist. He appeared in the Season Two episode, "Summer Sucks", where he is seeing giving psychotherapy to Mr. Garrison. He was killed by the extending giant firework snake.


Dr. Katz wears a yellow button-up shirt and a red tie. He is mostly bald with black hair on the sides and back of his head. He has black eyebrows.


  • The outlines of Dr. Katz are squiggly, referencing the "Squigglevision" animation style of the show.
  • Coincidentally, a few months after "Summer Sucks" aired, MAD Magazine did a simultaneous parody in which Katz, along with his son Ben and assistant Laura, who is also Ben's girlfriend, moved to South Park and set up a practice in town. Unfortunately, the trials of working and living in South Park, having to listen to head cases like Cartman (whose file contains over 450 folders) and Mr. Garrison, while Ben catches Laura in bed with Chef, quickly leave him questioning his decision, and after a broken pencil starts a chain reaction in which Kenny is decapitated by his framed diploma, he calls his New York clients begging them to take him back.
