Alex

Alex is a third grader who appears in the show. He is a minor character used mostly as a background character in most episodes, but has a speaking part in "Elwood City Turns 100!". He was also a cast member and "Buster's Dino Dilemma" as Brain's Fossil Partner where he portrays a dinosaur while stepping off the bus.

Apparel
He is normally seen wearing a tan sweater and brown pants. In the winter he wears a blue jacket with a yellow circle on it. In the episode Buster's Dino Dilemma Alex wore a white shirt that had purple on it, purple shorts with green on it, long green socks, and red and white sneakers. In the the summer Alex wears a light tanned shirt with a white collar, brown shorts, white socks, and blue and white shoes. He wears green pajamas as seen in the episode The World of Tomorrow. He also wears a blue swimsuit as seen in the episode Desk Wars. In the Winter Alex wears long brown pants, a green sweater, a cream colored scarf, cream colored mittens, and dark brown shoes.

Relationships
Being in Mr. Ratburn's class, we can assume he has some sort of relationship with the main characters. He is often seen with George and Jenna. He is most of the time seen with Maria and in a few cases talking to her in the background. His family has never been seen before. He also has been seen talking or hanging out with other minor characters in the background including some of the 4th Graders. There is a possibility he is friends with Muffy because the intro of "The Election" portrays him at her side at the presidential inauguration.
