While appearing to be a superhero, he is in fact a nemesis to Brown, who is lactose intolerant. Lactose Man usually appears in dairy product-based episodes. A variation of the Lactose Man character, Lever Man (albeit in the same costume) appeared in the episode "Shell Game", which is dedicated to oysters. Brown may or may not know the true identity of Lactose Man, as he identified Lever Man as being his apprentice, Paul. The Lever Man costume was revamped for use as Lactose Man. In real life, Brown is not lactose intolerant, which he revealed in "Breakfast Eats II".
