Brian is a bully who first appears in I Am Jackie Robinson. He attends school along with Xavier, Yadina, Brad, Charlie, Jin, Harper, Tyler, and Jamie.
In the original I Am Jackie Robinson, he doesn't allow anyone who isn’t wearing a puppy-dog coat like he is to play on the swings. His discrimination against Yadina prompts her to discriminate against the kid in a green coat. After learning a moral lesson from Jackie Robinson, Yadina reforms him (and herself) at the end of the episode.
In the remake of the episode, Brian is given a different appearance (he is now white) and role. In the remake, he bullies Xavier and Harper for their "weird" cultural lunches and says that the table they're sitting at should be for "normal" food only. He apologizes at the end of the episode.
He also appears in I Am Theodore Roosevelt and I Am Nellie Bly. In the online short "Stand Up", he teased Brad and Yadina for drawing comics. In We Are Siegel and Shuster, Brian bullies Brad and says his superhero comic isn't as good as Superman.
