Red

NOTE:Bertha should not be confused with her counterpart Sally who has the same hair and clothes.

Bertha (a.k.a. Red) is a character in the animated series South Park. Bertha (up until later seasons) was a character seen at the back of the main characters' class. People used to recognise her as the red haired girl. She has similar hair and clothes to another female in her class, Wendy Testaburger.. In Marjorine she was one of the girls at Heidi's sleepover. Bertha worked with Craig on the egg science project in Follow that Egg!.

Bertha is often confused with Sally (a.k.a. Powder). She has the basic same appearance, but without a butterfly clip in her hair. In fact, the two girls may be twins, or simply a case of the show's loose continuity.

Bertha's name is often given as "Red" in the scripts. She is also referred to as "Red" in "Follow that Egg!," making her real moniker a bit of a mystery.

Bertha wears a dark blue jacket and a matching pair of pants.
