Clyde is a fellow 4th grader in the boys' class. He's the fattest kid next to Cartman, who he ironically has expressed a very strong disdain for.

He had a colostomy at the age of 5 and according to rumor, he only has one testicle.

In the episode "The List", he was voted number one on the girls' list of cutest boys in class. It was eventually revealed that the girls voted for Clyde so they could go out with him and get free shoes since his father owns a shoe store at the mall.

Joining forces with Coon and Friends, Clyde also doubles as the superhero "Mosquito". His bold ideas and lemon bar recipes have helped countless in need.
