|Aliases||Boy in Blue Cap|
|First Appearance||Cartman Gets An Anal Probe|
This kid's been around since the beginning in his trademark blue cap with yellow brim - he's sang with the other kids in the Christmas coir, clapped along to Kyle's Mom is a Dirty Bitch, attended Cartman's ninth birthday party, and been along on plenty of adventures. He's been seen coming out of a different classroom but has snuck into the third grade classroom on occasion. He can also be spotted in the lunch room, playground and hallways quite frequently, even today. Despite his longevity, this fan favorite background character's never been named or had a speaking part in the show to date!
He had a friend icon in an early version of the game but was cut.
- His nicknames among fans include Brimmy, coined on an old fansite, Brad Dixon after an unseen character in "The Ring", Justin Hall after an unseen character in "T.M.I." and Boy in Blue Cap due to his trademark blue-and-yellow cap.
- His most visually prominent appearances are "Damien", where he can be seen quite a bit getting ready for and attending Cartman's birthday party, and "Merry Christmas Charlie Manson!" at the Mall of Nebraska, where he leads a riot.
- "Gnomes" is the only episode in which he can be spotted in the classroom, in a brief shot when Mr. Garrison makes the first group of kids, sitting by Pip Pirrup and Token Black.
- In "Fourth Grade" he's seen with the other kids before class begins and is even shown walking into the door - but is absent inside the classroom, disappearing!
