Tropes applying to the M.I.S.F.A.R.T.S.
- Ambiguous Situation: Given how they casually interact with Captain Underpants and are unfazed whenever he transforms back into Krupp, it's unclear if they are aware of the connection between the two.
- Badass Adorable: They're all adorable one way or the other and can do some pretty big things together.
- Canon Foreigner: Except for Jessica Gordon who was briefly shown in Book 6 with an alternate design, all of the kids were created for the Netflix series.
- Color-Coded Characters: Each of the kids have their own main color to stand out amongst each other.
- Erica-Teal.
- Jessica-Hot Pink.
- Sophie One-Sky Blue.
- Other Sophie-Light Green.
- Gooch-Pink.
- Dressy-Navy Blue.
- Bo-Purple.
- Stanley-Brown.
- Designated Victim: Erica excluded, the children often find themselves being brainwashed or captured by a given Monster of the Week.
- Idiot Ball: In "The Frantic Furies of the Fearsome Furculees", the kids end up losing Other Sophie in Ecuador and taking a ground sloth home with them instead, mistaking it for the former.
- Jerkass Ball: In "The Bizarre Blitzkrieg of the Bothersome Butt-erflies", Jessica and a majority of the group throw out George and Harold from the safety of the cafeteria to be devoured by the invading Butt-erflies.
- Limited Wardrobe: Thanks to the show's low budget, you won't be seeing them in new outfits anytime soon. The only exceptions involve swimwear or winter gear.
- Multinational Team: There's the biracial (her mother is African American and her father is Chinese) Erica Wang, the African-American Jessica Gordon, the Japanese Gooch, the caucasian Dressy Killman, Other Sophie, and Stanley Peet, and the Ambiguously Brown Bo Hweemuth and Sophie 1.
- La Résistance: They take on this role whenever they're fighting against Krupp and/or Melvin's totalitarian schemes.
- Ragtag Bunch of Misfits: An incredibly talented honors student, a shallow mean girl with her own Girl Posse, a weird kid with an unlucky streak, a free-spirited hippie, a hulking loner, and a sweaty farmboy who literally grows his own produce. Along with their leaders who have a long history as professional pranksters, this group is capable of performing incredible feats when necessary.
- True Companions: For the most part, the kids often look out for each other and are more than willing to help George and Harold when it comes to saving the day or just having fun.
Erica Wang
The 'Strong Female Character' this show deserves.
Click here to see her "Superhero Form"
Voiced by: Erica Luttrell
A cool and confident girl who is often involved in the adventures of George and Harold. Along with giving words of wisdom for the boys to follow, Erica is always three steps ahead of everyone on different occasions.
- The Ace: Based on Melvin's account, she's one of the top students at Jerome Horwitz and is involved in various clubs along with being president of several of them. Based on George and Harold's account, they think of her as being on a whole different level of cool. They even describe her as Batman without the angry grumbling.
- Action Girl: Most preeminently as Plungerina, where she’ll still be a badass normal when the situation calls for it.
- Afro Asskicker: She has her afro tied in a ponytail and has several moments of action throughout the series. The biggest example would be when she takes on the identity of Plungerina and proves to be great at kicking bad-guy butt.
- Ambiguous Situation: In episode 11, she somehow remembers (and keeps an object from) the "Krupp is a Corrupt Corporate Executive" timeline, hinting that there's more to her than we thought.
- In the season 2 finale, it's implied that she knows so many thanks to receiving help from her future self.
- Asian and Nerdy: Crossing over with Black and Nerdy. She's Chinese-African American and is one of the smartest and most proactive students in the school.
- Back-to-Back Badass: In "The Cunning Combat of the Covert Camoflush", she fights alongside Mr. Ree to stall the titular villain while the boys go to fetch Captain Underpants.
- Badass Normal: As Plungerina. Even though she lacks Captain Underpants' powers, she can still kick major villain butt.
- Boots of Toughness: She regularly wears yellow rubber boots, and while lacking any sort of superpowers, she's still the assertive and serious one of the class. Played straighter as Plungerina, where she maintains the trait of wearing boots.
- Boring, but Practical: In "Captain Underpants and the Confounding Concoction of the Crooked Combotato", her endings for the overall story are anticlimatic and lack the same zany energy that was displayed with her friends' story portions. One of her endings involved CU and the Combotato settling things in court.
- Brainy Brunette: Her hair's naturally brown, and she serves as the series' talented, ultra-competent smart girl.
- Brutal Honesty: Erica's unafraid to voice her opinions when it comes to George and Harold's antics. She openly tells them that their writing of female characters is offensive and is infuriating the female demographic. She also tells them that they don't have what it takes to get away with suspension like her.
- Catchphrase: When she isn’t pulling a Stealth Hi/Bye, she usually says “I’m out” whenever she leaves.
- Cool Big Sis: She fills out this role to the other kids in the Bad Future timeline. She also has these moments when interacting with George and Harold.
- The Cowl: In season 2, she becomes the Plumbing Hero: Plungerina to try her hand at super-heroism and proves to be very great at it. Although she decides to hang up her cowl when she realizes how dangerous being a superhero can be.
- Dark Horse Victory: Pulls this in the season 2 finale; George, Harold, and Melvin are so preoccupied with the nanobots and each other that they don't realize that they're not the only students left in the dome, and as a result, she steals victory from them at the last moment, pressing the victory button and emerging on top of the leaderboard as the winner.
- Dissonant Serenity: After learning Melvin was gonna blast her with "funny" videos, she simply shrugged it off.
- Expy: She brings to mind Lana Kane from Archer. Along with being hyper-competent black female characters with incredible talents, they also tend to serve as the Straight Woman to their wacky friends while making snarky remarks at their antics.
- Fluffy Tamer: Season 3 depicts Erica being able to tame a variety of creatures. Such as a horse, a rhino, and a barfalisk.
- Future Badass: Apparently grows up to become the President of Earth and achieve world peace.
- Good Counterpart: To Melvin. While Erica is one of the most intelligent kids at Jerome Horwitz who cares about her academic career, she has a good heart and is always looking out for her friends; unlike Melvin who only cares about himself, at least until the Season 2 finale. And while she does make critical remarks towards George and Harold regarding their shenanigans (just like Melvin), it usually comes out of the genuine concern and the desire to help them learn from their mistakes (unlike Melvin who only criticizes just for the sake of feeling superior). This even extends to their future counterparts; both come back in time to assist their younger counterparts, but Future!Melvin prefers a more public approach and is doing so for purely selfish reasons, while Future!Erica stays behind the scenes and her interference could also change the whole world for the better.
- The Gadfly: On multiple occasions, she’s shown to enjoy teasing and pranking the protagonists and occasionally, even Mr. Krupp.
- Granola Girl: A zigzagged example. She's shown eating plenty of ice cream but she later tells the boys that she prefers gluten-free muffins.
- Hammerspace: Where is she getting all that ice cream from?
- Hidden Depths: She has a lovely singing voice and is a skilled aerial silk acrobat.
- Honey Trap: A PG-rated example. In season 3, episode 11, Erica takes advantage of Melvin's crush on her to distract him for George and Harold to pull off their escape plan.
- Jerkass Ball: She gets handed this in "Captain Underpants and the Strange Strife of the Smelly Socktopus", in which she tricks George and Harold into getting themselves suspended… for the sake of a prank. Unfortunately, it comes off as more cruel than funny since the suspension was played completely seriously, and (as she puts it) it is not fun.
- The Leader: More often than not she'll lead the student body during times of crisis. In the bad timeline episode, George and Harold state that getting her to help will mean that everyone else will help too.
- Not So Above It All: While she is presented as very mature for her age along with having the most common sense, she likes to have fun and goof off with her friends.
- Once Done, Never Forgotten: She gets worked up when she remembers how her Uncle Frank overcooked a "perfectly good steak" during a family barbecue.
- Only Sane Man: Out of the rest of the cast, she’s the most level-headed.
- The Perfectionist: An amicable example. She's responsible for her academics and wouldn't do anything dangerous or stupid to jeopardize her current standing. She even admits that she intends to be a senator when she grows up.
- Playful Hacker: In "The Worrisome Wedge of the Water Warmongers", she hacks Melvin's H20blitterator 2000 to turn it against him. Unfortunately, it being dark when she hacked it results in it going rogue.
- Red Oni, Blue Oni: She serves as the blue to most of the other kids' red.
- Savvy Guy, Energetic Girl: Gender-inverted with her and George and Harold.
- The Smart Girl: She's hyper-intelligent and knows more about a given situation than the others. Lampshaded when the boys hire her to be the "Thinks" for M.I.S.F.A.R.T.S.
- Stealth Hi/Bye: She has a habit of popping in and out of scenes much to the confusion of the boys.
- Straight Man: She often comes off as this to the other kids.
- Tritagonist: Arguably the most prominent character in the animated series after the boys and Krupp/CU as she often plays a role in their adventures and is implied to be more than what she appears to be.
- Tomboy and Girly Girl: The tomboy to Dressy’s girly girl.
- Trademark Favorite Food: It originally seems to be ice cream, but later turns out it's actually gluten-free muffins as mentioned in granola girl above.
- Troll: She likes to pull pranks on the boys, especially in episodes 4 and 9, claiming that the best way to make a prank is to 'prank a prankster'. She even admits in episode 9 that she was never suspended at all and just wanted to mess with them.
- In season 3, she pretended to be the spokesperson of a foreign company so she can mess with Krupp.
- Tsundere: Type A towards George, Harold, and on some levels, Melvin.
- Twofer Token Minority: Is of black and Chinese-American descent.
- Unwitting Instigator of Doom: She was the one who suggested to George and Harold that they go to Superintendent Vil Endenemys to try to get Mr. Krupp fired before he can expel them, not knowing that Vil Endenemys is actually Melvin Sneedly's future self, who not only fires Krupp but expels George and Harold and then takes over the school with Melvin.
- Women Are Wiser: She's one of the more level-headed girls on the show and the boys often go to her for help during their misadventures.
Jessica Gordon and the Sophies
Left to Right (Other Sophie, Jessica, Sophie One)
Click here to see Jessica as "Messica Gorgon"
Jessica voiced by: Dayci Brookshire
The popular girls in the school. Jessica and her crew often engage in their own girly affairs but will often become involved in the wild antics of the show.
Tropes applying to Jessica Gordon
- Alpha Bitch: Downplayed, but she still has her moments, especially towards Other Sophie.
- Ascended Extra: Jessica has more speaking lines in Season 2. Goes to almost speaking in every episode of Season 3.
- Beehive Hairdo: It's bigger than her entire body!
- Brainless Beauty: She’s a known Alpha Bitch and ditz, particularly in season 2.
- Bunny-Ears Lawyer: She egocentric, snobbish, and yet has quite the magic touch when it comes to performing and sailing.
- Catchphrase: "Sophie One (*insert compliment or positive gesture*), Other Sophie (*insert insult or heavy-handed task*)".
- Disappeared Dad: We have yet to see her dad on the show.
- The Ditz: She definitely showed shades of this in Season 1, but it's much more noticeable in Season 2 where she, along with the other students, mistake a tree sloth for Other Sophie.
- Easily Forgiven: George and Harold don't hold anything against her (or the other students for that matter) for kicking them out of the cafeteria during the butt-erfly invasion.
- Entertainingly Wrong: When the school is attacked by Butt-erflies, she instantly accuses Melvin of being their creator. She bases this accusation on how he's the only one who's smart enough to create them in the first place (not to mention how earlier he attacked the students with an army of Croco-bats). She's in the wrong however since George and Harold were the ones that created the Butt-erflies.
- Generation Xerox: We meet her mom in Season 3, and the two of them look and act very similarly.
- Girly Bruiser: Most prominently as Messica.
- Good is Not Nice: While she is indeed an ally of the protagonists, she's been known for her insensitive and demanding behavior towards Other Sophie, so much so that she maltreats of her has become something of a once-an episode occurrence (as long as she's there).
- Hero of Another Story: In episode 10, after getting amnesia from the memory wipes, she and her crew become involved in protecting the whales. They end up ditching school to protect them from whale hunters and even get to ride with them in the end.
- Hidden Depths: As season 3 shows, Jessica knows a lot about sailing thanks to her whale-saving experiences in season 1.
- She also has exceptional talent when it comes to stage magic.
- Improbable Hair Style: There's no way she can get her hair to be that big every day and walk around like it's no big deal.
- Jerk with a Heart of Gold: Sure she's arrogant, entitled, and far from even a decent friend to Other Sophie, but still eager to lend a hand to George, Harold, and the other kids when they need it.
- Kick the Dog: She once left Other Sophie all alone at her birthday party and took off with her presents.
- Laser-Guided Karma: She gets turned into a real vimpire shortly after making fun of Other Sophie's new "harcut".
- The Leader: She takes on this role when the school is attacked by an angry swarm of Butt-erflies.
- Lovable Alpha Bitch: She has her mean girl moments, especially towards Other Sophie, but she's still very likable and gets along great with the other kids. Although she did kick out George, Harold, and Melvin when the Butt-erflies attacked the school and felt no remorse about it (of course the other kids are just as guilty as they went along with it).
- Monster of the Week: Thanks to Melvin using her as a test subject for his new ray gun, Jessica turns into "Messica Gorgon" the Vimpire.
- Narcissist: Befitting her archetype, Jessica is quite obsessed about her appearance; she panics over a strand of hair being out of place in the first episode, and she also tries to use Other Sophie as an umbrella to keep her hair from getting wet in two episodes of Season 3.
- Not So Above It All: While she does fill out a lot of characteristics of the mean girl archetype, she isn't above helping out George and Harold or partaking in their wacky adventures.
- Our Vampires Are Different: As a "Vimpire", "Messica Gorgon" gains power by feeding off the joy of her victims while turning them into miserable messes.
- Pink Means Feminine: Befitting her archetype, her main color is hot pink.
- Race Lift: In the book series she was white. Here, she's African American.
- The Social Expert: Downplayed. Jessica's talent as the Haars for M.I.S.F.A.R.T.S. is to manipulate enemies into letting their guard down.
- Token Evil Teammate: While not a villain, out of all the kids (excluding Melvin), she's easily the most obnoxious.
- Ungrateful Bastard: She’s almost always treating Other Sophie like trash, yet rarely (if ever) shows gratitude for the latter’s perpetual complying with her insensitive demands.
- Valley Girl: Speaks in this tone of voice.
- With Friends Like These...: Averts this to everyone, but she is NOT a good friend to Other Sophie at all. While she was the only one to show up at Other Sophie’s birthday party, she almost immediately left, and stole all of the presents while she was at it!
Tropes applying to the Sophies
- Ambiguously Brown: Sophie One has tan skin and brown hair, suggesting that she could be Hispanic.
- The Beastmaster: In Season 2, Other Sophie ends up becoming the Queen of the Croco-Bats after being left behind in Ecuador.
- Beehive Hairdo: They wear their hair in a style that mimics Jessica's, though Sophie One's attempt is more noticeable than Other Sophie's.
- Bespectacled Cutie: Other Sophie wears glasses, and they help empathize her endearing charm.
- Birds of a Feather: While it's not highlighted a lot, Bo and Other Sophie share the trait of being the more quiet students, as well as the
woobies of the class. Ironically, they're also the two tallest students. - Break the Cutie: Poor Other Sophie can’t seem to catch a break.
- Butt-Monkey: Other Sophie goes through quite a lot of misfortune; most of the time Jessica is to blame.
- Cute Mute: They don't talk, but that doesn’t make them any less endearing. Apparently, Jessica makes it a rule that Sophies aren't allowed to speak.
- Disappeared Dad: Like Jessica, we have yet to see their dads.
- Extreme Doormat: Other Sophie serves as this to Jessica regularly, as listed above and below.
- Gag Haircut: Other Sophie at one point, ends up coming to school with a large portion of her hair chopped off. And Jessica, being the terrible friend to her she is, takes the opportunity to ridicule her for it. The former is shown to have even tried to tape hair back together near the end.
- Generation Xerox: They look very similar to their mothers, and Jessica's mother tries to order them around just like Jessica does to their daughters.
- Girl Posse: Jessica is always shown in the company of Sophie One and Other Sophie.
- Hidden Depths: In the Christmas Special, Sophie One is the only student apart from Dressy who is shown smiling during the Christmas pageant practice. This hints that she has a love of performing or enjoys traditional holiday music.
- Huge Schoolgirl: Other Sophie happens to be not only the tallest of the girls but the second tallest of the kids (behind Bo).
- Ironic Name: Sophie One gets the codename “Helps” when she joins the M.I.S.F.A.R.T.S, but Other Sophie is the one who actually does most of the helping.
- My Friends... and Zoidberg: Jessica has blatant favoritism for Sophie 1 while treating Other Sophie like a put-upon servant.
- One-Person Birthday Party: Other Sophie was virtually alone on her birthday with Jessica leaving with the presents she brought.
- Redheads Are Uncool: Other Sophie has orange hair and is clearly the Butt-Monkey of the group.
- Redhead In Green: Other Sophie has orange hair and wears a green dress.
- Satellite Character: The Sophies only exist to serve as Jessica's clique. They haven't even spoken a single word in any of their appearances.
- Ship Tease: In season 3, Bo and Other Sophie seem to be crushing on each other.
- True Blue Femininity: Sophie One has a bright blue dress and is considered to be quite girly.
- The Voiceless: In Season 3, we learn that Jessica doesn’t allow them to speak, which implies that they can talk.
Steve "Gooch" Yamaguchi
Voiced by: Evan Kishiyama
An adorable boy who attracts misfortune to himself and is a good friend of George and Harold.
- Achievements in Ignorance: Despite having no idea how to operate a DJ booth, Gooch pulls off a brilliant performance for the talent show in the season 3 finale.
- Animals Hate Him: As part of his Butt-Monkey status, he's often in the jaws of a vicious animal.
- Asian Airhead: He's of Japanese descent and pretty dorky, but he defies the expected stereotypes since studying isn't his strength or something he enjoys. He's also not able to tell the difference between a phone and a beehive.
- Big Guy, Little Guy: He's the little guy to Bo's big guy.
- Big "WHAT?!": He gives one after Bo says he can turn into a Sabertooth truck, not realizing he was only kidding.
- Butt-Monkey: The most likely to suffer some sort of physical abuse in an episode.
- Casual Danger Dialogue: He's pretty nonchalant whenever he's faced with some sort of peril.Gooch (while being eaten by a python): Am I supposed to resist being eaten or let it happen? Because I'm flexible.
- The Chew Toy: His constant misfortune is generally played for laughs.
- Cloud Cuckoo Lander: Tends to say and do some rather weird things. Examples include trying to use a beehive and a rabid squirrel as a cell phone or how he hoped that some nearby birds would accept him as one of their own.
- Cute Clumsy Girl: Gender-flipped.
- The Cutie: Despite his clumsiness and naivety, he’s very sweet.
- The Ditz: He’s certainly not the brightest of his friends. As he tries to use random objects like a phone, remains completely casual about a python eating him alive, and loses the ability to recognize himself after dressing as Melvin.
- Dub Name Change: He’s called “Guille” in the Spanish version, while his real name’s Niestor instead of Steve. And the French version changes his surname to “Miroguchi” and his nickname to “Miro”.
- Extreme Doormat: Most of the time the kids take advantage of him without his okay. This includes making him pretend to be Melvin or drawing on his body with a permanent marker.
- Gadgeteer Genius: Subverted. The boys give him the role of tech genius for M.I.S.F.A.R.T.S. by process of elimination and Gooch makes it constantly clear that he couldn't operate technology if his life depended on it.
- Genius Ditz: He's a genuinely great pan flute and organ player, despite his clumsiness and incompetence.
- Hero of Another Story: Gooch is shown to be involved in some peculiar situations while the boys are in the middle of their adventures.
- Hidden Depths: He knows how to play the organ along with the pan flute.
- In the Hack-O-Ween special, he admits that St. Patrick's Day is his favorite holiday.
- Idiot Hair: He has a small one at the top of his head.
- In-Series Nickname: His real name is Steve but everyone calls him "Gooch".
- In Touch with His Feminine Side: He wears a pink collared shirt and isn't afraid to cry or express how he's feeling.
- Irony: Despite his apparent lack of technological skills, Gooch dreams of being a professional DJ and is put into situations where such skills are necessary.
- Keet: He's a very cheerful child.
- Lovable Coward: He's a timid but endearing young boy.
- The Smart Guy: He’s supposed to play this role for the M.I.S.F.A.R.T.S, but it’s ultimately subverted due to his complete lack of tech skills and airhead personality in general.
- Suspiciously Similar Substitute: Appearance-wise, Gooch bears a lot of similarities to Billy Doanbee-Ahiro, Harold's future husband if he were a child.
- Tiny Schoolboy: Zigzagged. While he is small (not to mention he serves as the little guy to Bo's big guy), but considering the average CU universe kid is a pint-sized kid, he's pretty much average height. His small size is simply noticed more due to his more young child-like attributes.
- What the Hell, Hero?: He calls out the boys for going too far in representing Erica as a monster vampire for their comics.
Dressy Killman
Piqua's most dedicated griffin enthusiast.
Click here to see her as the "Hangry Hypnosinger"
Voiced by: Dayci Brookshire
A mellow and cheerful young hippie girl and another friend of the boys.
- Ascended Extra: Speaks in almost every episode of the 3rd season.
- Badass Pacifist: She's a peacemaker, as well as a member of an entire team of badass adorables. She even manages to strike a full-grown man a long distance at one point, despite not even realizing it.
- Character Tic: She has a habit of singing out the last word of a sentence she's speaking.
- Connected All Along: Remember the Barefoot Farmer and Misty Meaner? Turns out they're part of Dressy's non-traditional family.
- Cute Bruiser: An adorable pacifist, as well as a Pint-Sized Powerhouse.
- Did You Just Flip Off Cthulhu?: She threw a dodgeball directly at Krupp's face to keep him from taking her comic book and faced no consequences for it.
- Disappeared Dad: She mentioned traveling to Ecuador with her parents before in Season 2, but in Season 3, we only meet her mom. Then again, it's not confirmed how Misty Meaner fits into her non-traditional family, so it could be a case of her having two mothers.
- Dub Name Change: She renamed “Perline” in French, “Eleganzia” in Italian, and “Ifaby” in Spanish.
- Fiery Redhead: Inverted. She has orange hair, but she's one of the more coolheaded students.
- Granola Girl: Free-spirited? All-natural? Environmentally friendly? Check, check, and, check.
- Heroic Sacrifice: Dressy tries to do this by saving Bo from Blah Borelock's petrifying smoke. It fails because she throws herself in his arms rather than actually ''pushing or pulling him away'' from the smoke.
- Hidden Depths:
- Dressy shows a lot of knowledge when it comes to Ecuador since she and her parents often travel there.
- She's fully versed in dream psychology and is an incredibly talented singer.
- Informed Attribute: The official guidebook states that she despises pranks, messes, and mischief, but she has yet to demonstrate any of this in the show.

- Ironic Name: Her last name is literally Killman, but she’s a sweet flower child.

Almost immediately after, she's hit with one of Camoflush's mind-controlling paintballs. She also lampshades her recompense as "instant karma".
- Mellow Fellow: A gender-flipped example.
- Mind-Control Music: As the Akuma of the week, the Hypnosinger can brainwash anyone who listens to her into becoming her next meal.
- Monster of the Week: After getting hit by a radioactive tire while sleeping in a cryogenic chamber, Dressy becomes the Hangry Hypnosinger, a wandering siren who hypnotizes people to eat them.
- Nature Lover: Befitting her hippie archetype, she proves to be quite knowledgeable when it comes to flora and fauna.
- Neat Freak: According to the official guidebook, she despises pranks, mischief, and messes. This has yet to be demonstrated in the show.
- New-Age Retro Hippie: Between her appearance and her interests (nature, singing, yoga, dreamcatchers), she comes off as this.
- Nice Girl: For the most part, she's genuinely courteous, kind, and optimistic.
- Odd Friendship: Despite her (supposed) disdain for pranks and mischief, she gets along great with George and Harold, the walking definitions of chaotic pranksters.
- Our Gryphons Are Different: Dressy isn't one, but she has an interest in golden griffins and brings them up now and then.
- Pintsized Powerhouse: She was able to punch a guy through a wall without breaking her meditation stance.
- Quirky Curls: Her orange hair is long and fluffy to portray her free spirit.
- The Smart Girl: She shares this role (and is more considerably more competent at it for that matter) with Gooch in the M.I.S.F.A.R.T.S.
- Sickly Green Glow: Her skin and eyes turn green when she became the Hypnosinger.

- Youthful Freckles: She sports some on her face.
Bo Hweemuth
Baby boy. Baby.
Click here to see him as "Claylossus"

- Ambiguously Brown: His skin tone is more tan compared to the other Caucasian students.
- Ascended Fanboy: He's a huge fan of Captain Underpants and was flattered when George and Harold made him the villain in their comic book. By the end of the episode, he now works with the boys in making Captain Underpants toys for the student body.
- Balloon Belly: He gets one after he indulges in Stanley's potatoes.
- Big Eater: While the kids are "falling several thousand feet down a cliff", George mentions that Bo once ate 13 tuna melts for lunch.
- He also manages to cram down at least 6 potatoes (one of which being a finger-length one) for George and Harold's game of plot potato.
- The Big Guy: Because of Bo's large size, he's given the role of "Thumps" for the M.I.S.F.A.R.T.S. Although he wants his friends to acknowledge that there's more to him than just muscle.
- Big Guy, Little Guy: He has this dynamic with Gooch whenever they're on screen together.
- Birds of a Feather: He and Other Sophie share the traits of being the class' woobies, as well as the quietest, and even the tallest students.
- Boisterous Bruiser: Zigzagged. He actually normally more timid and quiet than the other kids, but as shown in "The Frantic Feats of the Fearsome Furculees", and "The Cunning Combat of the Covert Camoflush", when he gets excited, he can get riotous. He also tends to lose his indoor voice from time to time.
- Bruiser with a Soft Center: He towers over other children his age and has greater strength than a muscular adult man, but he's really just a huge, gentle, shy, sweetheart.
- Dark Is Not Evil: He dresses in dark clothes and is known to literally spend most of his time in the dark, but he's a Gentle Giant.

- The Choice-O-Rama special shows Bo being able to create stop-motion animation.

- In Touch with His Feminine Side: He wears a pink bathing cap with flowers whenever he goes swimming.

- Never Bareheaded: Never without his beanie (or an occasionally-appropriate substitute).
- Nice Guy: Despite the rumors, he’s actually one of the sweetest and friendliest in the class.
- Parental Abandonment: He’s the only child whose parents weren’t introduced in season 3 episode 12. While this could be since they’re being saved for a future episode, it could also imply that he’s an orphan. Subverted as the Christmas Special reveals that he has a mom and dad. And they're HUGE.
- Power High: Bo lets the thrill of paintball get to him, to the point that he calls himself a god. Though it's downplayed since he calms himself down and apologizes for his behavior.

- Real Men Wear Pink: See In Touch with His Feminine Side.
- Ship Tease: In season three, he and Other Sophie seem to be crushing on each other.
- Super-Strength: He's capable of ripping apart a super thick rule book specifically stated to be made of polypropylenenote , an impossible feat that not even the more muscular and adult Major Messy could do.
- Took a Level in Dumbass: Horribly invoked. Melvin purposefully reduced Bo's intelligence during his transformation as Claylossus to make him even more of an unstable monster.
- Unwitting Pawn: Mr. Krupp used Bo's reputation as an unworldly bully to terrorize the other kids into submission as "scared children are good children".
- Walking Spoiler: It's rather difficult to talk about him without revealing the twist of his debut episode that he was a good guy all along.
