The protagonist. A normally level-headed and intelligent 15-year old, Lee considers himself just a normal guy with a normal school life. That is until his first day of 10th Grade, when he is framed as the mastermind behind the "Greatest School Prank in High School History" and is now forced to go to Detention for the rest of the year. With the help of friends both new and old, he makes it his goal to find out who the real mastermind is and get his life back on track.
The Ace: Played straight and subverted. Despite his supposed geeky rep before the series start, Lee gains instant popularity after getting detention. Also, he's a pretty good action hero for an Ordinary High-School Student, as he seems to be able to doanything; from being a star football player, to a top violinist, to a brilliant actor. This also counts as a subversion, in that while Lee is fairly intelligent and resourceful, he struggles through the more physical aspects of being an Action Hero (for example, the first time he swipes a skateboard to escape, he does have some trouble with his coordination). Not to mention his reputation as a legendary troublemaker was completely false.
It's also subverted a bit, since the skills that make him The Ace are really a result of the mark underneath his tattoo. It was given by his Eminence to his grandfather, and then it was passed down to every direct descendant of the Ping family. According to his Eminence, the mark comes with great power, so everyone who was marked and their families have potential of being just as much of an Action Hero. And yes, this includes his father and his brother.
Asian and Nerdy: Downplayed. He gets good grades, but uses his brain more for his investigations and is almost nothing like a stereotypical nerd.
Brown Eyes: Mentioned in universe by Brandy (to be specific, "dark brown with flecks of gold with a slight hazel tint in the rain", which is more detail than he ever noticed himself). They fit him personality-wise, as he's a down-to-earth guy.
Can't Get Away with Nuthin' : In general. Naturally, on the one day Lee wants detention to protect himself, he has a free pass. Even trying to set up the bullies fails to nab the right culprit.
Clear My Name: His initial motive is to find the person who framed him for the big prank and be free from detention.
Cool Board: He's pretty handy with a skateboard, and has often used one to get out of sticky situations. In fact, the very first episode of the show opens with him being chased by the Cleaners on a skateboard before going back to show us how he got into the situation.
Cool Loser: Being detached from any clique and having a few friends gives off this vibe. Though the prank boosted his popularity, he's still retains shades of this. It's actually because he is this that he was chosen to be framed for the prank, and the focus of Lynch and V.P. Victoria's plans. Why would anyone notice if something happened to the boy who doesn't stand out, or even care if something did?
You risk your life everyday, no big deal? But you can't tell a girl how you feel about her? Lame!
Trademark Favourite Food: Lee spends the whole episode “Mastermind” trying to get a Sloppy Joe, only for it to be knocked out of his hands or him being startled into dropping it. He finally gets one at the end of the episode.
A wanna be gangster Latino and one of Lee's best friends. Cam may not the smartest or bravest student around, but he always has Lee and Holger's back and can actually be quite clever if he wanted to. However, he as a strong desire to be part of the in-crowd and is one to quickly take advantage of any opportunity he can get, which is why he fully embraces Lee's newfound popularity.
Brilliant, but Lazy: While not as smart as Lee, Cam does have his moments of brilliance. They just only come around when he's actually trying. For example, he is actually very knowledgeable about History and claims it's because it's the only subject he finds interesting enough to bother learning. Also, when he and a few other students were being blackmailed for cheating he was the only one who went all out with the investigation into who was doing it, and was the first to figure out that it was Grayson.
Casanova Wannabe: Most of his appearances feature him hitting on at least one of the girls.
Hidden Depths: When he was Student Council President, it's shown that he actually has some talent as a leader and is a decent speaker. On a lesser note, it's also revealed that he genuinely finds History to be very interesting and is even smarter than Lee when it comes to the subject.
Hypno Fool: He acts like am monkey whenever the Trigger Phrase "butterscotch" is spoken and stops with the phrase "queen of hearts". This was caused when he was hypnotised by The Amazing Finnwich at Lee's early birthday party untill "Finding Finnwich" when the spell was finally lifted. This was also used to help pull off the first prank.
Jerk with a Heart of Gold: He often prioritizes his popularity and reputation over his friends, but will put it aside to help Lee out when needed.
Lovable Coward: At first, he didn't want to get involved in Lee's exploits and only got dragged into the mayhem when it was a school-wide threat. He carried shades of this even after he decided to join in. Finally dropped in the series finale.
Student Council President: Downplayed as he often shirks on his presidential responsibilities and is mainly in it for the fame.
Tiny Guy, Huge Girl: As evidenced by his love interests, particularly with his girlfriend, Brandy.
Lee's other best friend, Holger is a foreign exchange student with a very quirky personality and habits, to say the least. He's the most energetic and fit of the three boys, and is always the most eager to help either of them with any problem. Though sometimes, he can be a little too eager. Because of this, Holger is Lee's primary "go-to" guy whenever he needs a distraction, or for someone to handle something that he can't do.
Keet: He's highly energetic and constantly cheerful, with a loud voice and tendency to over-react in a silly, but endearing way. And he's definitely In Touch with His Feminine Side, given his expertise in cooking and love for beauty products like hand cream, dressing up, and his hair. Threatening to cut or soil his hair is probably the worst thing you can do to him.
Plucky Comic Relief: Holger's not really that good at sneaking around or lying, nor is he particularily book smart, which leaves his role as the guy that keeps up team morale and provides light comedy in times of stress.
Puppy-Dog Eyes: Uses them on occasion, like to get Cam to put on a disguise in “The Hydra".
Undying Loyalty: One of his most prevalent traits. If you are his best friend, he will do all he can for you and never leave you behind. This actually caused him some internal conflict when had to choose between helping either Lee or Cam when they were fighting.
Biffy T. Goldstein
Initially The Bully, Biffy is Lee's detention buddy, tech-wizard, and mission control. He is primarily responsible for helping Lee find his way around the school and then his way back to the detention room, making Biffy the most important person in Lee's missions. Unfortunately, since Biffy has a rep he wants to keep he insists that he and Lee aren't friends and that they shouldn't communicate outside detention. But the more they work together, the more Biffy stats warming up to the idea.
The Big Guy/The Lancer/The Smart Guy: Depending on the episode, he can either offer Lee technical support from his laptop or an extra hand for carrying heavy objects or beating up people. He also takes on the role of the Lancer in some episodes, though other characters get their share, too.
* Childhood Friends: Surprisingly enough, with Kimmie. They've known each other since they were babies, but grew apart in 7th Grade. After spending a detention together though, they decide to start being friends again. Albeit not in the public eye due to their reputations.
Foil: To Lee in a sense that he's a clique-less detention regular due to getting busted nearly every day for infractions that may or may not be his fault. He even has parents that are deeply involved in the MWF conspiracy.
We Used to Be Friends: With Kimmie in season 1. They eventually repair the relationship in later seasons.
A professional journalist in the making and one of A. Nigma's school reporters and news anchors. Tina is known for taking her job very seriously and isn't one to hide the truth. The good news for her is that the school is full of big stories that need exposure, but the bad news is that she has to deal with her overwhelming co-anchor, Chaz. Lee's had a crush on her since 5th Grade, but unfortunately, his growing popularity as the Prank Master and the many secrets he is hiding have not helped his chances.
Determinator: If there is something suspicious going around A. Nigma, Tina will find all the answers.
First Girl Wins: Lee's had a crush on her for a long time, and vice versa. After several complications, they do end up getting together.
The Smart Girl: Her thirst for knowledge leads to her being an excellent researcher and detective. In the webisodes, she starts piecing together the mystery of Coral Grove, and when she helps Lee with the secrecy surrounding the school she does a lot of the problem solving and putting information together.
Lovable Nerd: Her determination in searching for the truth is truly admirable.
Tsundere: Type B. She's usually generous and kind, but she will bite back on people that insist on annoying her.
Principal General Barrage
A. Nigma's new principal, Barrage is a half-cyborg war veteran who doesn't even know the meaning behind having an in-door voice. Strict and intimidating, Barrage intends to make sure that every student appears as proper and we'll-behaved as possible, and he doesn't care how far he would have to go to keep it that way. With lack of a better term, he is Lee's primary enemy and the number one person he is always trying to avoid whenever he is on a mission.
Dean Bitterman: Principal Barrage does everything he can to make Lee's life a living hell and even tries to get him expelled. The funny thing is, they're on the same side. Barrage just doesn't like Lee Ping.
One-Man Army: He's one of the few characters powerful enough to take on more than one of the Hazmats and Tazel-borgs.
Papa Wolf: Say what you will about the man but, he will NOT leave his students behind. Does this for Lee Ping involving a Heroic Sacrifice in the Dance part 2.
Sadist Teacher: He held Football tryouts that involved bombs and cannons. He takes pleasure in physically dragging Lee to Detention and has mocked him for missing out on school events because of Detention.
Bait-and-Switch Tyrant: Not only does how cruel his punishments are depend on his mood, but also whether or not he's being brainwashed. It's clear he does care about his students, but Good Is Not Nice, and just how not nice he is can vary.
Unwitting Pawn:Victoria manipulated him into committing various incidents that would've guaranteed dismissal from his position. Later, the Council take control over him after implanting a Mind-Control Device.
Student News Team
Tina's co-anchor, a flamboyant and rather arrogant reporter who is always trying to steal her spotlight. While Tina handles the more serious school news, Chaz would rather focus on school gossip and rumors, and is quick to take advantage of dirty secrets in order to humiliate his fellow students. He even has his own school show that he delightfully calls "Chaz's Corner!"' which is dedicated to doing this.
Attention Whore: Pretty much the only reason he's even on the News Team is that he loves the camera so much.
Kent Brockman News: He spends more time fussing about his hair and talking about how awesome he is than actually giving news. Typically, he and Tina will bicker for a while about who gets to say something or interview someone before one of them finally does it, and if it's not him, he's liable to either pout or interrupt her.
The Dandy: He cares a lot about his looks. He wears fancy clothes and doesn't want to be on camera until he's dumped a can of hair product into his hair.
Hot Scoop: He certainly thinks he's the hottest thing around, and he does care about his appearance.
It's All About Me: Tends to take over the news segments his very own "Chaz's Corner!"
The Friend Nobodylikes: It seems like Chaz has no actual friends aside from Stepak, who is just his camera man and so has no choice but to follow Chaz. He considers himself one of the popular kids, but not even they seem to like him.
Small Name, Big Ego: He's constantly talking about how amazing and handsome he is, even if no one else thinks so.
The camera man and technician of the News Team. Normally seen carrying a camera and following Chaz or Tina around with it.
The Quiet One: He has a few lines here or there, but a majority of the time he just lets Tina and Chaz do the talking.
The newest addition to the Glamazons, Brandy would do anything to keep her status as one if the hottest and most popular girls in A. Nigma, even if it means having to be bossed around by Kimmie. As soon as Lee gained major popularity due to the prank, Brandy was quick to latch onto him and declare herself his girlfriend. While initially coming off as a typical High School Alpha Bitch, the softer side of Brandy's personality starts emerging the more time she spends with Lee.
Amicable Exes: While their relationship was completely one-sided on Brandy's part, her and Lee still get along fairly well after Brandy came to terms with Lee's feelings for Tina and started dating Cam.
Lovable Beta Bitch: She's not that bad once you get to know her and she can be really thoughtful when she wants, but still be a bitch about it.
Clingy Jealous Girl: To Lee and Tina in the early seasons, hating any interaction they have. Thankfully, she matures. She also shows shades of this whenever Cam flirted with the cheerleader, Toni, and this was before they became official.
Hidden Depths: When she starts opening up more to Lee and Cam, it's shown that she's not all that bad a person. She can be smart, sensitive, and even considerate, given that the situation calls for it.
Not so Above It All: At first, Brandy was rarely quiet about how she refused to do anything silly looking or just downright immature. But as the episodes past and she starts joining in on more of Lee's plans and adventures, it's clear that she's not above doing even crazier things than the guys.
Tomboy and Girly Girl: In terms of their relationship with Lee, the "girly girl" to Tina and Jenny's "tomboy"
Tsundere: Type A. She desperately wants to fit in with the Glamazons, so she acts in a way that will impress Kimmie, a.k.a. cold and uncaring towards other people. Whenever someone tries to show her up, she explodes and starts yelling at them in an attempt to re-gain control of the situation. It takes a few seasons and lots of Character Development to reveal her soft side, and we see that she does open up to people if she trusts them enough and can genuinely be quite sweet.
Yes-Man: To Kimmie, again. Eventually, she gets fed up and refuses to continue being this, getting kicked out of the Glamazons as a result.
Beautiy, brains, and attitude, Kimmie has everything one needs to be the queen bee of A.Nigma and leader of the Glamazons. Like most of the popular students, she is all for making fun of those lower than her in status and fully utilizes the power she has over the other Glamazons. However, she does have a more sensitive side, which only starts resurfacing once she rekindles her childhood friendship with Biffy.
Aloof Ally: She will help Biffy sometimes… if she feels like it.
Blondes are Evil: Not as evil as her mom, but she can be pretty nasty when she's in a bad mood.
Childhood Friends: Surprisingly enough, with Biffy. They've known each other since they were babies, but grew apart in 7th Grade. After spending a detention together though, they decide to start being friends again. Albeit not in the public eye due to their reputations.
Et Tu, Brute?: Was always one to defend her mother and quickly gets mad whenever Biffy or Lee insists that she's evil. But once she realizes that her mom really is as evil as they say, Kimmie freezes her using the crystal gun in order to stop her from attacking Lee and his friends.
We Used to Be Friends: She was close childhood friends with Biffy. They grew apart after a while, but later in the series, they start re-kindling their friendship.
Brad Von Chillstein
One of the most, if not the most, popular students in the school, primarily due to his dad being a famous action hero celebrity. Due to a combination of both his need to continue being seen as the cool guy, and just plain cluelessness, Brad tends to get in the way of Lee and his friends during dire situations. Thankfully for Lee, Brad tends to be mostly talk and is completely harmless. Though that doesn't mean he isn't capable of pulling off some sinister plan in order to keep his popularity.
Big Man on Campus: He's the most popular student in school. Subverted when Lee's rising popularity status knocks him off his pedestal.
The Ditz: Tends to see the world as if it ran completely on movie cliches, going as far as believing that his dad's B-movie plots are legit and effective in real life.
Wrong Genre Savvy: As revealed in Episode 21, he believes that movie elements are applicable to real-life. Ironically, the nicknames and tropes he assigned to Lee and the other students were all pretty spot on.
Vocal Evolution: At first, Brad had a much deeper voice before it eventually became more high and nasally
Seemingly the popular student in charge of keeping the status quo in check at A. Nigma.
Manipulative Bastard: Uses his knowledge of the school population and the social status to keep the popular kids in power.
The Social Expert: He's one of the key popular students controlling the rest of the population. When he and Kimmie team up to make Cam the school president, he does most of the social stuff – while Kimmie doesn't care about any of the non-popular students, Dickie seems to know each one by name and can even name a hobbie or characteristic that can be used to befriend them, which makes him pretty good at manipulating people.
One of the jocks and star Quarterback of A. Nigma's football team. Tends to be a jerk, but like most of the students he is actually a decent guy.
Jerk Jock: Starts off like this toward Lee, but actually proves to be a nice and loyal guy once Lee gets on his good side.
Obfuscating Stupidity: He pretends to be bad at math so that Greta, who he has a crush on, will tutor him.
Security Blanket: Despite being in High School and one of the toughest jocks there, Steve still carries around his “Bub-bub”, a so-called lucky towel which has been in his family for generations and is covered in sweat and dirt. He is not ashamed of this, either, and is devastated when his Bub-bub is stolen.
Geek Physiques: They're all fairly skinny and/or short. In addition, Beth has a retainer and Greta has a unibrow.
The Smart Guys: They represent the nerd clique, and fit the stereotype nicely.
President of the Mathletes and a member of the Genius Club. Irwin is one of the students who has a genuine vendetta against Lee, which stems from how they used to be friends and fellow Mathletes, but Lee was always considered the smarter one. Surprisingly, he also loves dancing and is very good at it, going as far as having a DDR math game in the club and his own dance uniform.
The nicest member of the Mathletes, and the only one to branch out and interact with even the more popular students. Greta is, notably, smart yet eccentric enough to keep up with Holger's interesting quirks and isn't afraid to join him in even the most absurd things. Naturally, this makes her the most important girl to Holger.
Affectionate Nickname: Holger calls her "Honey Roasted", which is her sidekick name whenever they are helping Lee on a mission.
Badass Bookworm: Nerdy, quirky, and capable of taking out a group of Hazmats for almost hurting her boyfriend.
Extraverted Nerd: The rare female version. She's on pretty good terms with people outside of her clique, and has even been part of a Love Triangle where the other two werepining after her, rather than the other way around.
Love Triangle: Was in the center of not one, but two love triangles. The first was between Holger and Ed the ex-Water Boy. The second was between Holger and Jerk Jock Steve.
Token Good Teammate: Of the Mathletes, she's the nicest one and is friendly towards people not in her clique.
Lead singer and guitarist of the band the "Dudes of Darkness." Usually spends his time in the men's bathroom, where the band practices and where he comes up with new lyrics and songs.
Dark Is Not Evil: Despite all appearances, he is one of the nicer and more chill students that Lee befriends.
Loners Are Freaks: They used to be cool until they picked up (or rather, were brainwashed into picking up) some... odd, slightly disgusting habits.
Lonely Together: Though they were friends before becoming unpopular, they definitely qualify now, sticking together despite the off-putting habits.
¡Three Amigos!: They were certainly this for the first few seasons and before being outcast. However, in Season 3, Jenny is updated to the main cast, and more or less leaves the other two for Lee and Tina.
The supposed leader of the Outcasts, and cursed with the non-stop desire to suck his thumb. Out of the Outcasts, Lou wants his coolness back the most, and will do anything for it. This has caused a few problems for them and Lee as a result.
Standardized Leader: For the outcasts. He's do most of the talking when interacting with other students, but he doesn't have much character to him.
The Outcast cursed with the need to eat anything and everything.
Why Did It Have To Be a "B" Word?: Whenever he hears any word that starts with "B", he has a mental breakdown and will do nothing but stutter "B-b-b-b-word" while pulling his bandana over his ears.
The only girl of the Outcast, and cursed with, what most students consider, the most disgusting action: the need to always stick her finger up her nose. Jenny was the first student in the core cast to find Finnwinch's book, and her desire to solve its mysterious promoted her to becoming an important part of Lee's gang. She also quickly develops some feelings for Lee, since he was the first non-Outcast guy to not be bothered by her curse and to see her as a friend.
Because You Were Nice to Me: After Lee decides to help her group out again (even after she stole hisCool Key), she soon helps out him out with his investigations. This is also the reason why she was quick to develop feelings for him, and later the Serpent- because they were the first guys outside the Outcasts to show her any semblance of acceptance and kindness.
Defrosting Ice Queen: Due to being ostracized for her uncontrolled habit, she's usually cold towards other people. She's more open to people with whom she has established a friendship or has a crush.
Grayson is everyone's typical smart man and he takes great pride in that. However, he is also one of the nicer students and is more than willing to help, if necessary. Which is why it surprises Cam when Grayson turns out to be the blackmailer and the one responsible for humiliating him, Cyrus, and most of the popular students.
Genius Cripple: The only student we've seen with an obvious disability
High School Hustler: He's even made the handicapped toilet stall his little office to sell high-grade papers.
Nerd Glasses: The only male nerd and member of the Genius Club to wear glasses.
The Dog Bites Back: He attempts this. As a child, he was bullied by the jocks and cool kids, going through situations such as being forced to eat an insect sandwich or having hot soup poured on his lap as everyone else just laughed. Since those same kids attend A. Nigma, Grayson took the opportunity to try and make their lives just as miserable. So he tricks and blackmails nearly everyone in his elementary class with threats of exposing them as cheaters unless they do as he says. This includes Cyrus and Cam, who weren't even involved in the bullying. When he finally pushes them to abandon everything they love, and even gets Cam suspended, Grayson comes to realize that trying to get back at bullies just wasn't worth the misery he caused them. In the end, it just felt horrible.
Nadene is easily recognizable by her large green hoodie and love for Hip-hop. But while she doesn't look the part, especially when compared to the others, she is actually one of the smartest students. She also a member of the Student Council.
A Jive Turkey talking student who is assigned to work with the school's servers and was also the DJ at Brandy's party. He has a strange obsession with Apple Splat and peanuts, and is always seen consuming either one. Eventually, Lynch develops a strong admiration for Lee, and is more than willing to join in on his missions because he wants to be just as cool.
Rogue Agent: Becomes one after Vice Principal Victoria's arrest.
Trademark Favorite Food: Lynch has two: a beverage called Green Apple Splat ("It's the splattiest!") and peanuts. His constant consumption of the latter annoys several characters and makes him not very good at being sneaky. Both turn out to be important - he's always talking about Splat because he actually owns the company, and in the Season 2 finale, Lee uses the trail of peanut shells he leaves behind to track him down.
Other Students and Cliques
Recurring Extras: Often seen wandering around the background. Even though they're not needed for the plot, they're always there.
Treacherous Advisor: Once Lee told everything he uncovered (thus far), she confessed her involvement in a top-secret brainwashing experiment to him and that Barrage is most likely after everyone associated with it. In reality, her and Barrage's roles are reversed, and she fully intended to get rid of Lee as well.
Sue Ping, Lee's mother
Action Mom: First seen in "Clogspiracy" when she shows she's handles guns before.
Drives Like Crazy: As her son's best friend Cam puts it, "every drive with you is like an adventure in almost dying!"
The Heavy: As of Season 4, his actions directly affected the plot.
Heel-Face Turn: Upon finding out his heritage and the reasons behind his separation from his parents, he becomes a sort of ally towards Lee and his friends, though this is mostly overshadowed by his new-found enmity against Cassandra.
Revenge Before Reason: From targeting the Pings for supposedly abandoning them to going after Cassandra for kidnapping him from his family and turning him into an assassin. Unfortunately for him, the latter effortlessly incapacitates him. Twice.
Bumbling Dad: Despite being a scientist, he gives off this vibe at times.
Dark Secret: He has been working for Mann, Wurst, Finnwich for years and only recently found out they were Evil All Along and kidnapped his first son.
Distinguishing Mark: He has the same tattoo as his son which is used to cover his own three-banded birthmark. Like his father before him, he gave Lee the same tattoo but didn't get to do the same for his first son, the Serpent.
Lethal Chef: He claims he can't even boil water, which is why his wife does all the cooking.
Plot Allergy: A severe one for fish. Serves as a tie to the Serpent.
When You Coming Home, Dad?: Gives off this impression due to his infrequent appearances in episodes, though it's subverted by Lee's lack of worry.
Mr. and Mrs. Goldstein, Biffy's Parents
Ambiguously Jewish: They speak with very obvious and exaggerated Jewish accents, but there has yet to be anything shown that confirms they actually are.
