The Charlie Arc is a now-defunct fanfiction written and published on FanFiction.Net by ThreadbareSP. Each chapter of the story is written in the form of a script and is approximately the length of a half-hour South Park episode. Five installments were released, with seven originally planned. The story is now being broken up into five different pieces: "Gender Confusion: The Trilogy", which is a compilation of the first three chapters of the Charlie Arc ("Charlie", "Brainwashing", and "Sisters Suck".), "Project B", "Post-Dramatic Stress Disorder", and the two previously unreleased chapters, each published as autonomous stories: "Fall of the House of Pierzynski" and "Mistletoe Immunity".
