"Charlie Brown" is a character in Kill Bill: Vol. 1. He is a timid staff member of the House of Blue Leaves and served O-Ren Ishii and her associates. He is terrified of them and is forced to comply with their erratic demands, as the proprietor of the House warned him that putting a toe out of line will get his head cut off.
He is given the nickname "Charlie Brown" due to his resemblance to the Peanuts character.
