Uncle Budd is Butters Stotch's uncle. He lives in Los Angeles, California with his wife, Nellie. He has only appeared in the episode "AWESOM-O" and it was a fairly brief appearance. His name was unknown until "The Return of Chef" when Butters states that he has molested him, implying he is a pedophile although Butters may have been talking about a different uncle. He then made a cameo appearance in "Fishsticks" and "Pinewood Derby".
He has brown, curly hair and his facial hair is growing back. He has thick eyebrows and has wrinkles on his face. He wears a light blue button-up shirt over a plain white t-shirt. He wears a Los Angeles Dodgers baseball cap, which indicates that he may be a fan of the team.
- "AWESOM-O" - Brief appearance when Butters and Eric Cartman stay at his house.
- "The Return of Chef" - Mentioned only; Butters states that he molested him.
- "Fishsticks" - Cameo appearance.
- "Pinewood Derby" - Cameo appearance.
Budd is mentioned to have been a pedophile in "The Return of Chef". Once again, this may have been another uncle.
Other than that, Budd has been shown in "AWESOM-O" as intelligent because he realizes Awesome-O 4000 is just Eric Cartman.
