Titular duo
Fanboy and Chum Chum
Fanboy on the left, Chum Chum on the right.
Voiced by: David Hornsby (Fanboy), Nancy Cartwright (Chum Chum, pilot), Nika Futterman (Chum Chum, series)
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.
They are the only characters to appear in all of the episodes.
Tropes shared by both:
- Batman Parody: Their costumes are somewhat influenced by those worn by Batman and Robin. This is especially noticeable in the original Random! Cartoons pilot, where the green portions of Fanboy's costume were originally gray and Chum Chum's tunic originally had string ties like Robin's instead of a chest insignia resembling his face.
- Cheerful Child: Both are hyperactive and joyful kids.
- Children Are Innocent: These boys are very naïve and naturally unaffected.
- Childish Tooth Gap: Both have these.
- Clothing Reflects Personality: Chum Chum wears yellow and orange, reflecting he's the nicest and most innocent, while Fanboy wears green and purple, showing he's also funny but can be more serious than Chum Chum.
- Cloudcuckoolanders: The Theme Tune makes it clear.
"A little coo-coo, Fanboy and Chum Chum."
- Comically Missing the Point: Many conflicts could have been avoided if they were more aware of their surroundings. One episode has them think that anything a baby plays with must be a baby toy, and then throw out everything in their house once one messes with everything they own.
- Cool Mask: Fanboy has one, although he lacks any real powers. Or, so you think...
- Depending on the Writer:
- It varies by episode which one of the two is smarter and more rational than the other. In some episodes, Chum Chum is more smart and level-headed than Fanboy, while in others, it's the other way around.
- Their attitude toward Boog also tends to vary by episode. In some episodes such as "Dollar Day" and "Chimp Chomp Chumps", they seem to dislike Boog and have no problem acting rude and antagonistic toward him, while in other episodes like "Fanboy in the Plastic Bubble", "Freeze Tag", and "Prank Master", they seem to actually care somewhat for Boog and act relatively friendly toward him, though they're still intimidated by his aggressive behavior and will still act rather antagonistic toward him if he harasses them first.
- Dumbass Has a Point: They sometimes tend to make rational explanations in spite of their idiocy, usually Chum Chum.
- Early Installment Character-Design Difference: The original pilot short on Random! Cartoons had the green parts of Fanboy's costume colored gray and depicted Chum Chum with string ties on his chest similar to those on Robin's tunic rather than an insignia bearing the silhouette of his face.
- Expressive Mask: In this case, their masks are the same color as their eyelids.
- Expy: Most viewers associate them with SpongeBob and Patrick due to their dimwitted nature and hyperactive personalities.
- Fat and Skinny: Chum Chum and Fanboy respectively.
- Fanboys: So much that they wear costumes that make them look like super heroes for all their life. They actually are superheroes as revealed in "Brain Freeze". Fanboy even names himself after this trope.
- Fartillery: Chum Chum's underwear "explodes" on Yo in "Prank Master".
- Feud Episode: The episodes "Pick a Nose", "Cold War", "No Toy Story", "Lice Lice Baby" and "Heroes vs. Villains" show them against each other.
- Gasshole: Both of them are this, but it's more prominent with Fanboy.
- Held Back in School: It is implied by Mr. Mufflin in the first episode that they were both held back at least one year in his class.
- Heterosexual Life-Partners: To the point where they are intent on becoming "immortal companions" in "Fangboy". In "Separation Anxiety", their friendship is so strong that if they are apart, it causes a rip in the space-time continuum.
- Keet: Both are very hyperactive.
- Large Ham: Just about everything they say is spoken loudly and with a lot of cadence.
- Limited Wardrobe: The guiltiest of the cast. They never take off their superhero costumes, even for bathing. This is because they have secret identities and taking them off would reveal them.
- Meaningful Name: "Fanboy", since he's a fan of everything and "Chum Chum" since "Chum" is a nickname for "friend", which he is with Fanboy.
- Morality Pet: Kyle's kinder sider is brought out when these two are with him.
- Never Bareheaded: They never take their masks off once.
- Nice Guy: Although annoying as two protagonists can get, both of them are friendly kids for the most part.
- No Indoor Voice: From "Total Recall":Chum Chum: Fanboy only has an outside voice. He was born that way.
- Oblivious to Hatred: They're usually pretty much oblivious of Lenny and Kyle's hatred of them.
- Only Known by Their Nickname: Both of them, though in "Separation Anxiety" Fanboy reveals his true name, Tobias.
- Though that's just speculation, because the name he signs the letter with is "Lance Corporal Tobias Cranapple Fanboy III" as a reference to dramatic western movies. Whether any of the names used are actually his real name isn't very likely.
- Non-Standard Character Design: Both are constructed more realistically and carefully than the rest of the characters. Especially prominent in this shot
◊. - No Sense of Personal Space: Both of them, but Fanboy is more prone to this.
- Parental Abandonment: Their parents are never seen nor mentioned.
- Ping Pong Naïveté: Whichever one is the more intelligent of the duo varies per episode.
- Precocious Crush: "Lice Lice Baby" has them both develop crushes on the school nurse Pam and fight each other over winning her affections. In the end, they stop after learning that Pam is Man-Arctica's girlfriend.
- Reality Warper: Both of them are all but stated to be this.
- Heavily alluded to in "Separation Anxiety", as separating them would rip a hole in the space-time continuum and nearly cause the whole universe to fall apart. It all goes back to normal once the two are reunited.
- When the two go camping on the Frosty Mart roof in "Fan vs. Wild", the roof somehow transforms into a snowy mountaintop like Mt. Everest, and they actually nearly freeze to death. The roof returns to normal whenever Kyle doesn't cope with it.
- In the climax of "Brain Freeze", they somehow gain actual superpowers to fight the Frosty Freezy Freeze monster; they stop working in the end, and when Lenny asks why they never use them, Fanboy claims the powers only activate if the situation is very serious and distressful.
- Red Oni, Blue Oni: Both are the red to Kyle's blue. In episodes and scenes where it's just them, they tend to swap places with Fanboy being responsible (blue) and thinking up some sort of kooky plan (red) while Chum Chum is an excitable Cheerful Child (red) who tends to be the voice of reason when his friend flies off the handle (blue).
- Secret Identity: Both are revealed to have these, but it's unknown what they are.
- Selective Obliviousness: They actually choose to be unaware when they want, especially when Kyle first came to the school.
- Superheroes Wear Capes: Well, they think they're superheroes, but they still have capes.
- Trademark Favorite Drink: Frosty Freezy Freeze, of course.
- Underwear of Power: They wear actual underwear outside their suits. They're upset without them, as they hold their powers.
- Vague Age: They look like they could be 9-11 years old.
Tropes applying to just Fanboy:
- The Artifact: The original pilot short on Random! Cartoons establishes that his codename comes from idolizing the superhero Fan Man. As Fan Man was Dropped After the Pilot, this renders Fanboy's codename meaningless (though "Robo-mance" indicates at one point that Fanboy will call himself Fan Man in adulthood).
- Beware the Silly Ones: Fanboy is a cheerful guy who is almost never serious. But he becomes no nonsense when it comes to protecting Chum Chum.
- Big Brother Instinct: Fanboy is fiercely protective of Chum Chum, especially when Yo tries to kidnap him.
- Compressed Hair: Due to wearing a cowl that covers almost his entire face.
- Cranium Compartment: His head can open like a jar at will whenever he wants. Becomes important in "Brain Drain" as it's used to lose his brain.
- False Teeth Tomfoolery: "The Tell-Tale Toy" depicts him as wearing dentures for a brief gag.
- Goo Goo Getup: "Battle of the Stands" has him pretend to be a baby to attract customers to his and Chum Chum's lemonade stand by wearing a bonnet and sucking on a pacifier. It fools everyone except Lupe and Yo.
- Jerk with a Heart of Gold: He can be rude, inconsiderate, and insensitive fairly often, but despite all this he still has some good nature in him and genuinely cares about Chum Chum and others (albeit to a lesser extent).
- Phlebotinum-Induced Stupidity: He literally loses his brain in "Brain Drain" and acts like an even bigger idiot than usual.
- Screams Like a Little Girl: Fanboy in "Man-Arctica the Ride". The other kids all think it was a girl who was screaming the whole time.
- No Indoor Voice: "Total Recall" even states he only has an outside voice.
- Verbal Tic: Tends to pronounces the "Fr" in "Frosty Freezy Freeze" apart from each word:Fanboy: He's got a Fr-osty Fr-eezy Freeze on his head! Get it!
Tropes applying to just Chum Chum:
- Artistic License – Linguistics:"Stealers are bad people! I don't wanna be a bad people!"
- Distressed Dude: In "Saving Private Chum Chum" when he swallows a ball and Mr. Mufflin mistakes him for a toy, locking him up.
- Captain Obvious:
- In "Fangboy", he easily recognizes Fanboy's "vampire" bite as just a bite from a mosquito, and in "The Incredible Shrinking Fanboy", he points out the sunflower grew overnight when Fanboy believes he's shrinking. Both times, he's dragged in to believe him.
- In "Hex Games" when Kyle tries to start the game by casting a spell and nothing happens, Chum Chum flatly replies, "Um...you put it in the Hex Box?" and shows the game console that powers it.
- Cute, but Cacophonic: He has a rather high pitched voice and his screams are so loud that they could send a grown man flying!
- Deuteragonist: His name come second in the title.
- Dumbass Has a Point: Sometimes is much more competent than Fanboy, and easily sees right through his naivety.
- Good Is Not Dumb: Usually he's smarter than Fanboy, depending on the plot.
- HULK MASH!-Up: "The Incredible Chulk" revolves around him becoming a Hulk pastiche when Fanboy makes him laugh and his laughing fit causes him to transform into a big orange monster with immense strength and the ability to jump really high.
- No-Neck Chump: His lack of a neck is a plot point in the episode "Fangboy", where Fanboy (who believed he had become a vampire due to waking up with a mosquito bite on his neck) tries to bite Chum Chum on the neck so he can also be a vampire. Upon discovering that Chum Chum doesn't have a neck, Fanboy decides to take him to a neck specialist named Dr. Acula so he can have one added surgically.
- Prosthetic Limb Reveal: He is revealed to have a prosthetic left leg in "Battle of the Stands".
- Took a Level in Badass: When he's just himself, he needs Fanboy to protect him from Yo. But as Super Chum he is strong enough to break out of any prison.
- The Voiceless: Becomes this throughout most of "Saving Private Chum Chum" after swallowing a ball, with the only sounds coming out of his mouth being squeaking.
Supporting cast
Kyle the Conjurer (aka, Kyle Bloodworth-Thomason)
Voiced by: Jamie Kennedy
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.
- Ambiguously Gay:
- When he and Fanboy are trying to decide which board game to play, his first pick is "Mr. Unicorn's Teddy Bear Dress Up Fashion Show".
- In the "Fanboy and Chum Chum Bible", which is a compilation of ideas Eric Robles wrote down before the show started, Kyle was originally supposed to have a crush on Yo, and although he has never showed any interest in her in the actual series (nor have the two spoken to each other), this could make him Ambiguously Bi.
- When he states that the town isn't big enough for two wizards in There Will Be Shrieks, he makes some feminine hand movements.
- In "Fanboy A'hoy!", we get this:Kyle: And will there be decorative soaps with fancy perfumes?! [Pause] Excuse me for taking pride in my personal hygiene.
- Aesop Amnesia: Despite admitting his friendship to the titular duo in "Sigmund the Sorcerer", he forgets it episodes later.
- Alliterative Name: His designation of Kyle the Conjurer is at least phonetically alliterative.
- Anime Hair: Has a shaggy hairstyle that's quite big and spiky, due to his head shape.
- Anti-Hero: He serves as one due to being sometimes good and other times antagonistic.
- Baby Morph Episode: He gets turned into a baby in "Crib Notes".
- Badass Cape: Wears a black one, which symbolizes his mischievous personality.
- Blank White Eyes: Gets these while summoning the Balhok in "There Will Be Shrieks".
- Braces of Orthodontic Overkill: Kyle has fairly normal braces, but they're extremely noticeable due to his large teeth. In "Night Morning", he wears an enormous headgear complete with its own train set.
- Breakout Character: His popularity with fans may have lead him to get a bigger role in Season 2.
- British Teeth: He has huge braces to go along with his giant teeth.
- The Chew Toy: His first episode revolves around him getting beat up for agitating others, which sets up his source of humor quite nicely.
- Clothing Reflects Personality: Wears red and black, which are the colors of anger and darkness respectively.
- Cloud Cuckoolanders Minder: He serves as one to Fanboy and Chum Chum, often calling them out for their crazy shenanigans and what they are doing should not be the task at hand.
- Chick Magnet: In the episode "Face-Eating Aliens From Planet X" shows that he is liked by some of the girls; Marsha likes his braces, Lupe likes his accent, and Francine loves it when he makes the sky "dark and evilly".
- Child Mage: Albeit one with very inconsistent magic skills.
- Deadpan Snarker: He makes quite a lot of snide remarks, especially in regards to Fanboy and Chum Chum's idiocy.
- The Dog Bites Back: Kyle doesn't seem to have ever played a video game before, but he spends the entirety of "Hex Games" getting berated and injured throughout the video game Sigmund created (which he seems to have created just to screw with Kyle, to boot), but Kyle keeps trying due to the chance for readmission in to Milkweed... which turns out to be all for nothing, as Sigmund calls him a fool and gloats in a Did You Actually Believe...? speech, saying Kyle "never learns". But Kyle proves that he did at least learn how to play video games, and uses his new skill to beat the snot out of Sigmund.
- Everyone Has Standards: Kyle does show hints of remorse for FB and CC at times, such as sticking up for them when calling out Mr. Trick when they initially failed on their quest, and at Icemas one time, he even joined in crying with everyone else when Fanboy rips off Mr. Mufflin's Man-Arctica costume, exposing him as a fraud.
- Evil Counterpart: He is one to Fanboy and Chum Chum. While they wear bright colored clothes, his clothing is darker. He is actually serious and refuses to be funny, and unlike them, he despises anything.
- Evil Laugh: He gets one in a few episodes.
- Evil Sounds Deep: Though not a villain, has a deep, masculine voice.
- There are quite a few episodes where his voice tends to sink into a low, demonic tone - quite frightening for viewers.
- Expy: His grouchy behavior, Butt-Monkey status and constant suffering at a pair of idiots oblivious of the pain they cause him makes him one of Squidward, alongside Lenny.
- Fiery Redhead: He can tend to be rather angry and has red hair to go along with it.
- Green-Eyed Monster: He becomes this in "The Book Report of the Dead" and "Speed Eraser", both thanks to Fanboy.
- Hypocritical Heartwarming: Against the Candyman in "There Will Be Shrieks" when he hears the Candyman put a curse on Fanboy and Chum Chum, though he'd prefer to think it's more of a Not Big Enough for the Two of Us against another dark arts practitioner than anything to do with Fanboy and Chumchum.Kyle: So! You think you can come to my town and cast a spell on my two idiots!?
- Inept Mage: One episode has him try to conjure up a bunch of notes, but he instead spends the night conjuring up things like newts, nets, and knights.
- Inferiority Superiority Complex: There are hints of this in "Sigmund the Sorcerer", which reveals that there is a much more popular wizard from his same school that he wants to be on par with.
- Irony:
- The episode "Cold War" reveals he never actually had anyone want to play with him before; yet he himself does not want to play with Fanboy and Chum Chum because they add random rules to their games.
- In "Speed Eraser", after his revenge on Fanboy with the magic eraser doesn't go as planned, he literally attaches it to him and lists off what will be erased upon doing so. Yet seconds later, it's his own body that gets erased, when Fanboy tries to hold onto him.
- It's All About Me: He tends to be full of himself a lot. When he was the eraser-er, he even called himself "King of the Chalkboard".
- Jerkass Has a Point: Kyle makes valid explanations from time to time, especially in scenes where he had to cope with FB and CC's idiocy.
- In "Fangboy" when Fanboy was led to assume he was bitten by a vampire, Kyle was right to say he's not really a vampire because he's just delusional about it from a mosquito bite.
- In "Cold War", he screams against both boys for making up rules for their games, not that they mind it, however.
- In "Fan vs. Wild", he chews them out for selecting the Frosty Mart roof for their camping trip and snubs Fanboy for smelling the stink from the air duct to the men's washroom.
- Jerk with a Heart of Gold: Kyle is very full of himself, but multiple episodes establish that he genuinely does view Fanboy and Chum Chum as friends and is willing to help them out.
- Kindness Ball: Tends to slip into this part depending on the episode, usually in appearances when he does not speak. He actually approves of Fanboy's double arm talents in "Fanbidextrous", finds his deformed Nightmare Face funny along with the rest of the class in "Funny Face", and in "A Very Brr-y Icemas" when Fanboy accidentally takes off Mr. Mufflin's Man-Arctica costume, Kyle is actually crying along with the rest of the visitors.
- Laser-Guided Karma: Jealous that Fanboy steals his title as board eraser-er, he gives him an eraser that literally erases everything. When he literally attaches it to Fanboy near the end, Kyle's own body gets erased as a result.
- Leitmotif: Usually whenever he appears, the background music consists of horns and harpsichords, reflecting his wizard-y self. When his bad side is shown though, it's replaced by a rather ominous Ethereal Choir.
- Mage in Manhattan: Well, more like "Mage in the Suburbs" but since he's a transfer student who hails from a Wizarding School, he counts.
- Magic Misfire: Quite a bit, especially when Fanboy and Chum Chum get a hold of his magic wand.
- Meaningful Name: The name "Kyle" means "narrow".
- Morphic Resonance: When disguised as Chum Chum in Lord of the Rings, he keeps his braced teeth. Also, his voice doesn't change.
- New Transfer Student: Well, technically, he was expelled from his Wizarding School, but same thing.
- Not So Above It All: While he usually plays the Only Sane Man, he's been shown to be as quirky as the rest of the cast at times. One particular example is where the class takes advantage of Mr. Mufflin not being able to see them play with toys because of his laser eye surgery, and Kyle is among the kids playing with toys (or in his case, a bunch of magic equipment). He also laughs with the other children at the janitor's surname being Poopatine in "The Janitor Strikes Back".
- Oddly Visible Eyebrows: His brows can be over his bangs at times; other times they are under them.
- Only Sane Man: When the plot demands it. Usually he's one of very few characters to have common sense. Other times, he's just as quirky as the rest of the characters, especially in background appearances.
- Out-of-Character Moment:
- In "Man-Arctica the Ride", Kyle was one of the kids excited for the grand opening of the Ice Scream Extreme and even enjoyed riding it.
- In "Funny Face", he was one of the kids who laughed at Fanboy's altered face for the photo.
- In "A Very Brr-y Icemas", Kyle was among the crowd cheering for Fanboy as he told his wish; he even joined in crying with everyone after he accidentally ri
- Punched Across the Room: By Lupe in "Wizboy" for accidentally sitting on her lunch.
- "The Reason You Suck" Speech: Delivers two of them, one in "Chicken Pox" and another in "Cold War":Kyle: Something's gone wrong! This is all your fault, you made me lay a bad egg! I got so mad, I probably hard-boiled it! And now, I'm going to be a chicken for the rest of my life!Kyle: Grr...you're cheaters! Charlatans! With your...made-up rules and airborne livestock?!! ''I call shenanigans!!
- Red Eyes, Take Warning: He briefly has these in "Tooth or Scare". Has them again in "Heroes vs. Villains" when making his entrance.
- Red Oni, Blue Oni: The blue to Fanboy and Chum Chum's red.
- Series Goal: To return to the Milkweed Academy for Wizards, though this doesn't manifest until Season 2.
- Sesquipedalian Loquaciousness: Tends to speak this way at times. To give an example...Kyle: I intend to re-matriculate at my alma mater post-haste!
Chum Chum: Kyle's talking gibberish. - Slasher Smile: He sometimes flashes these when he gets an idea or plans revenge.
- The Stool Pigeon: In "The Book Report of the Dead", Kyle becomes a Petty Peter when he tries to tell on Mr. Mufflin that Fanboy forgot to do his book report. Fanboy turns it on him by using Necronomicon to write it. He becomes one again when he catches Fanboy "back-sassing" Mr. Mufflin which results in the duo separated.
- Surrounded by Idiots: Considering Fanboy and Chum Chum hang around him a lot, it's to be expected.
- Teacher's Pet: In "The Book Report of the Dead", Mr. Mufflin even refers Kyle as "suck-up".
- Temporarily a Villain: In "Separation Anxiety", "The Winners" and "Speed Eraser", Kyle is a main antagonist, the third episode being the most extreme example.
- Token Evil Teammate: As far as Fanboy and Chum Chum's circle of friends go, Kyle is the most frequent one to be given an antagonist position, and a lot of his magic is definitely not of the good kind.
- Tome of Eldritch Lore: He's casually used the Necronomicon to get out of jams.
- Took a Level in Jerkass: In "Speed Eraser", an erasing dance routine by Fanboy causes Mr. Mufflin to give Kyle's job as the board eraser-er to him. Out of jealousy, he spends much of the episode planning revenge with an eraser that erases anything literally, but it only causes Fanboy to have more fun, so this leads him to literally attach the eraser to Fanboy, much to his horror and shock. He instantly loses his jealousy though, when Fanboy accidentally erases his entire body.
- Tsundere: Type A. He's always rejecting Fanboy and Chum Chum, but it has been hinted several times that he craves their friendship. Especially in the Sigmund the sorcerer episode.
- Vague Age: He says he's a preteen, so he can be anywhere around 9-13.
- Vitriolic Best Buds: Fanboy and Chum Chum believe they are best friends with Kyle, even though he makes it clear that he wants nothing to do with them. Although, in a show where you wouldn't expect there to be any Character Development, Kyle has actually started liking Fanboy and Chum Chum, and he even admits they're his friends in "Sigmund the Sorcerer."
- Vocal Dissonance: His voice is naturally lower than most other preteen boys in real life, sounding like he’s in his mid 20s.
- You Can't Go Home Again: He cannot return to his former school, Milkweed Academy, because he was expelled after turning his teacher into a raspberry flan. His goal is to be readmitted, but of course it always fails.
- Youthful Freckles: He is a red-headed preteen wizard with them.
- Younger Than They Look: He's a preteen, which is around 10-12 years of age, but he looks like he's from his mid-teenage years. It comes through in his voice as well.
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
Voiced by: Jeff Bennett
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 possessions far more than the people around him and enjoys picking on kids much younger than him.
- Artistic License – Linguistics: Lampshaded, as Fanboy and Chum Chum giggle at him right after he says this:Boog: Get out of this bubble and take your boppin' like a man! ...s.
- Asshole Victim: He gets his comeuppance for being a bullying Jerkass more often than not. Examples include the onslaught of humiliation and torment inflicted on him by Fanboy and Chum Chum in "Chimp Chomp Chumps" and his attempts to bop the aforementioned duo constantly backfiring in "Fanboy in the Plastic Bubble", as well as him being trapped in the bubble and floating away at the end of said episode.
- Beard of Evil: Jerkass with a small beard on his chin.
- Berserk Button: Don't mess with his Chimp Chomp machine, or you will be bopped.
- Big Bad: The closest thing the series has to one.
- Bubble Boy: In his childhood, he was forced to live in a plastic bubble due to having an air allergy. A flashback demonstrating this ends with him declaring that he will one day make everyone as miserable as he once was.
- The Bully: To just about everyone, although his primary target is younger children. He even considers "delivering knuckle-sandwiches" a hobby.
- Butt-Monkey: He tends to suffer quite a lot of humiliation, pain, and misfortune, typically as Laser-Guided Karma for his Jerkass behavior. A few good examples of this would be "Chimp Chomp Chumps", "Fanboy in the Plastic Bubble", "Bubble Trouble" and "Freezy Freaks".
- The Chew Toy: Any unfortunate or humiliating thing that happens to him happens not only because he deserves it, but also for the amusement of the viewers.
- Cool Car / The Precious, Precious Car: The proud owner of Sandy.
- Companion Cube: He talks to the Chimp Chomp machine as if it's his girlfriend. He's the same way with his car named Sandy.
- Even Evil Has Loved Ones: "Evil" might be stretching it, he's more just a big Jerkass, but no matter how rude he is to everyone, he cares deeply for his Chimp Chomp arcade system, treating it like a person and lover. He also shares a similar love for his car Sandy.
- Evil Laugh: He has a rather crazy one.
- Expy: His greedy and hotheaded behavior brings to mind Mr. Krabs, while his antagonist role and bullying of children could be compared to Vicky
(which isn't surprising, considering that both shows are made by the same production company). - Freudian Excuse: He had a miserable childhood living in a plastic bubble due to air allergies and vowed to make everyone feel his pain one day. That is to say, in the present day.
- High-Pressure Emotion: He has shown this at least three times. In one instance, he gets so angry that the lid to his cup hat blows off.
- Jerkass: He's a very rude, hostile, mean, and aggressive individual who regularly bullies and physically attacks others for his own amusement.
- Knife Outline: He has it done to him in "Monster in the Mist", although he doesn't scream until there's a fork approaching his crotch.
- No Celebrities Were Harmed: Boog's voice is basically John Travolta's Welcome Back, Kotter character, Vinnie Barbarino.
- Screams Like a Little Girl: In "Monster in the Mist".
- Sensitive Guy and Manly Man: Manly Man to Lenny's Sensitive Guy.
- The Slacker: He never actually does his job, preferring to arrive 7 hours late and play Chimp Chomp all day.
- Shock and Awe: One episode ends with his getting the power to shoot lightning out of his hands as a side effect of a shock collar.
- Shout-Out: He's an obvious John Travolta parody with a sweet ride named Sandy as an homage to Grease.
- Red Oni, Blue Oni: The red to Lenny's blue.
- Unusual Euphemism: In "The Frosty Bus", Boog says to the titular duo, "I am gonna bop the boppin' bop out of you two!" In "A Bopwork Orange", after Agent Johnson says he is fired, Boog replies with, "What the... bop?!"
- Vanity License Plate: Boog's license plate reads "BORN 2 BOP".
- Would Hit a Girl: He has no problem bopping Yo along with the other kids.
- Would Hurt a Child: He also has no problem bopping kids in general, when he himself is an adult.
- Younger Than They Look: He's supposed to be in his teens, but he looks like he's in his early twenties.
- But in Back From The Future, they went back five years to when Boog was first employed, so he has to actually be in his twenties.
Leonard "Lenny" Flynn Boyle
Voiced by: Jeff Bennett (pilot), Wyatt Cenac (series)
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.
- Beleaguered Assistant: He's always the one to clean up after the other characters' messes, despite being the assistant manager of the Frosty Mart.
- The Chew Toy: Fanboy and Chum Chum (almost always unintentionally) cause him a lot of misfortune.
- Companion Cube: He's infatuated to his bike named Bikey and is devastated when it's destroyed in "The Great Bicycle Mystery".
- Deadpan Snarker: His response to a lot of the craziness of the show is snark.
- Early Installment Character-Design Difference: While an African-American, he was depicted as a blond Caucasian in the original Random! Cartoons pilot.

- Rule of Funny: He debuts in the episode "Excuse Me", where Mr. Mufflin permanently excuses him from school as a result of reading a torn-apart excuse note that Fanboy, Chum Chum and Kyle tried to tape back together.

Voiced by: Steve Tompkins

- Companion Cube: He seems to have a personal relationship with his mechanized chair, Brenda.

This backfires on him when Kyle uses his new video game prowess to beat up the real Sigmund.

- Would Hurt a Child: In an episode where the cast invite him to play freeze tag, Man-Arctica interprets the game as having to freeze the others and traps FanKyleChum in a block of ice. While this was mostly out of a great misunderstanding of how the game works and of no ill intent, after Yo and Lupe give him a wool sweater that agitates his allergies, Man-Arctica feels betrayed and tries to freeze the rest of the children out of anger.
