A list of Original Characters exclusive to Threadbare South Park. Canon characters are also listed, but only tropes applying to their appearances in this series are listed, since they are so in-character and listing tropes they demonstrate in the actual show would be redundant, as they are already listed on the characters page for the official show.
The main character of the series. A mostly good-natured, but awkward and impressionable girl who happens to look like a boy and have a name generally associated with boys. Becomes a periphial member of the boys' group, but is not treated any differently than anyone else the boys interact with.
- Adorkable: Shy, sweet, and can act a bit silly here and there.
- Big Sister Instinct: She's very concerned about her little sister, and is devastated to learn that her baby brother was taken away by child services.
- Blatant Lies: When explaining her bruises in the first story, she claims to have fallen down the stairs and ran into a table. They're actually from her mom.
- Character Blog: She has an ask account and a Twitter.
- Cool Loser
- Dreadful Musician: She plays ukulele... poorly.
- Happily Adopted: By the Marshes at the end of "Sisters Suck."
- Hilariously Abusive Childhood: Well, the hilarious part is up for debate, but she didn't really have the best childhood.
- Lady Looks Like a Dude: Clearly.
- The Lancer: At times.
- Littlest Cancer Patient: Briefly in the first story, after being force-fed bleach by her own mother.
- Mistaken for Gay: Due to her gender-neutral appearance, Bebe asks her out. Later, Stan's parents refer to her as a "little lesbian girl".
- Nice Hat
- Official Couple: With Kyle (kind of).
- She also has a close relationship with another OC, ParkerPants'.
- Original Character: Charlie and her siblings are all original characters. A case of Tropes Are Not Bad; Charlie is so flawed and interacts so well with canon characters without causing OOC moments, she could very well be an actual character on the show.
- One of the Boys: Downplayed. Although Charlie is indeed a member of the boys and she isnt girly at all, this doesnt stop them from thinking that she is just a typical girl.
- Sexy Secretary: Kenny thinks her tits are massive in "Mysterion Has Tittyvision", where she (as Stethoscope) becomes the secretary for Coon & Friends, though this is just Kenny being deluded.
- Sixth Ranger: Or, in the case of the boys, the fifth ranger.
- The Smurfette Principle: While other girls appear in the series, she's the only one to have a consistently major role.
- Super Senses: Her alter-ego Stethoscope has this power.
- Tomboy with a Girly Streak: Charlie normally wear boyish clothes, has Boyish Short Hair, a name usually associated with boys, and enjoys boyish stuff and gross humor. However, she can occasionally show a girly side, much to the boys disgust.
- Unpopular Popular Character: She has very few friends in-universe, but many readers love her and her stories.
- Viewer Gender Confusion: In-universe example.
- Wise Beyond Their Years: Much like Stan and Kyle. She has a wide array of business and pop-culture knowledge.
