Characters: Fanboy and Chum Chum
Fanboy and Chum Chum
Fanboy on the left, Chum Chum on the right.
Voiced by: David Hornsby (Fanboy), Nika Futterman (Chum Chum)
The eponymous, hyperactive duo, who live by the rule of no work and all play. They spend most of their free time hanging out in the local convenience store or having all kinds of wacky adventures in their house, which lacks any kind of adult resident. They are both comic book nerds (although much less so than Oz) and get ecstatic about the tiniest things.
Kyle the Conjurer (aka, Kyle Bloodworth-Thomason)
Kyle is a snarky, grumpy kid who, depending on the episode, takes the role of either the antagonist or a tritagonist for Fanboy and Chum Chum. He actually possesses wizardly powers, although no one believes him.

An incredibly energetic girl
who loves her digital pet Yamaguchi
. She is one of Fanboy and Chum Chum's schoolmates. Being vulnerable to all things cute and tiny, she becomes extremely obsessive whenever Chum Chum is involved, often to the point of insanity.
Ozwald "The Oz" Harmounian
Voiced by: Josh Duhamel
A nerd who lives and runs a comic book shop with his mother. Considered by Fanboy and Chum Chum to be the smartest human being to have ever existed, due to his excessive knowledge of comics.
Boogregard "Boog" Shlizetti
A local bully who works in the Frosty Mart convenience store alongside Lenny (although using the word "work" is probably giving him too much credit). He appears to treasure his possesions far more than the people around him and enjoys picking on kids much younger than him.
Leonard "Lenny" Flynn Boyle
Voiced by: Wyatt Cenac
Like Boog, he works in the local Frosty Mart. Lenny appears to be permanently stressed out/spiritless and absolutely loathes Fanboy and Chum Chum's hijinks. Basically a standard Butt Monkey
of the show.
Fanboy and Chum Chum's class' Apathetic Teacher
. Speaks with a ridiculously monotone, dull voice and is exceedingly hateful of his job. Sometimes refers to Fanboy as "Purple Kid" and to Chum Chum as "Talking Raccoon".
- Apathetic Teacher: He's said more than once that it's only twelve years until his retirement.
- Everything's Deader with Zombies: He becomes a zombie in "The Book Report of the Dead" when Fanboy says a spell from Kyle's Necronomicon.
- Eye Beams: Mr. Mufflin gets laser eye surgery in "Saving Private Chum Chum", allowing him to literally shoot lasers out of his eyes.
- Jeff Bennett
Fanboy and Chum Chum's schoolmate. Appears to be friends with Yo.
Janitor Russ Poopatine
Voiced by: Steve Tompkins
The janitor at Fanboy and Chum Chum's school.
Voiced by: Estelle Harris
She's... well... Oz's mom
. Runs a comic book shop alongside Oz.
An elf created by Kyle who is often seen making notes for him.
An artificially intelligent machine Fanboy has built in the future, the Dollarnator was sent back to the past to help the boys when they were in trouble. He has a lot of different skills and abilities that often prove to be unexpectedly helpful for the titular duo.
Sigmund the Sorcerer
He and Kyle used to attend the same school for wizards, which is how they became rivals. Sigmund is clearly more acknowledged and advanced in wizardry than Kyle, much to Kyle's anguish.
A superhero and the titular duo's idol.
Thorvald the Red
