Numbuh 1
Numbuh One / Nigel Uno

""Kids Next Door, battle stations!""

The leader of Sector V, an overworking agent who loves every minute of his job. He is widely considered one of the best of the best. However, his paranoia and stubbornness have gotten in the way of doing his job effectively at times. He is voiced by Benjamin Diskin.


 * The Ace: Hell yes, to the point he surpasses legendary ace Chad (who is not happy about this)
 * Adorably Precocious Child: Tries too hard to not act his age.
 * Adorkable: Very much so, due to his No Social Skills.
 * Agent Mulder
 * Always Someone Better: The reason for Chad's downfall is because of him being this.
 * Authority Equals Asskicking
 * Bald of Awesome
 * Berserk Button: Has at least three: being charged at a restaurant, messing with his teammates, and too much stupidity and loonacy for him to tolerate.
 * Cain and Abel: The Abel to the Delightful Children's Cain.
 * Captain Picard
 * Chick Magnet: He has quite the suitors, with Lizzie, Rachel/Numbuh 362 and even his own tree house all over him.
 * Cloudcuckoolander: Not to the same level as Numbuh Three, but let's just say a lifetime of being fully dedicated to his job has made him a paranoid weirdo (granted, most of the time he's right, but still)
 * Cool Shades
 * The Comically Serious: Part of his charm and hilarity is his tendency to take extremely seriously even the most menial of tasks, be it due to his Properly Paranoid personality or his clear lack of social skills.
 * Conspiracy Theorist
 * Crack Defeat: "Operation: E.L.E.C.T.I.O.N.S."
 * Deadpan Snarker
 * Dork Knight
 * Duty First, Love Second: In "Operation: G.I.R.L.F.R.I.E.N.D.",
 * Hair-Trigger Temper: Not as bad as Numbuh Four, however, and is usually justified given he tends to be surrounded by the weirdness and idiocy of the world he lives in.
 * Henpecked Husband: Preteen version. He usually tends to comply to his girlfriend Lizzie's demands, no matter how much he dislikes them (then again, Lizzie is quite the Clingy Jealous Girl)
 * The Hero
 * Hero Worshipper: He admires Numbuh Zero, the greatest hero in KND history.
 * Heroic BSOD: Gets this after the Delightful Children turn him into an adult until Numbuh Five gives him a Rousing Speech to get him back.
 * Informed Flaw: According to everyone else in the show, his butt is so huge it's the kind of badonkadonk spoken only in legend. This is Played for Laughs, of course.
 * Innocently Insensitive: Sometimes.
 * Insulted Awake: Several times.
 * Jerk with a Heart of Gold: Less on the "Jerk" part than Numbuh Four, but he still fits, as Numbuh 362 states at one point. He's reckless, stubborn, hot-tempered and can come across as aloof and insensitive due to his No Social Skills and extreme devotion to his job. Nevertheless, he's still a good person who is fully devoted to justice and always, always puts his friends above himself.
 * Kissing Under the Influence: In "Operation: L.I.Z.Z.I.E.".
 * Living Emotional Crutch: To Numbuh Four, as evident when he's completely devastated when

 * Officer and a Gentleman
 * Official Couple: With Lizzie,
 * Only Child Syndrome: Nigel is the only Sector V member who doesn't have any brothers or sisters.
 * Opposites Attract: With Lizzie.
 * Paper-Thin Disguise: As Billy in The Grim Adventures of the KND. Also, another episode says he fooled the Toiletnator with a T-shirt that said "I am not Numbuh 1".
 * Platonic Life Partners: With Numbuh Five. They're very close partners, yet they haven't shown any romantic interest in each other (contrary to what shippers say).
 * Playful Otter: Gets turned into one in "Operation: G.R.A.D.U.A.T.E.S.".
 * Prematurely Bald: Thanks to the Delightful Children.
 * Properly Paranoid: While his theories are somewhat plausible in his world, they're so convoluted that it's easy to see where he's stretching it.
 * Real Men Wear Pink: He likes Rainbow Monkeys, as seen by his underwear.
 * Red Oni, Blue Oni: The red to Numbuh Five's blue.
 * Ship Tease: Despite his relationship with Lizzie, he has quite the tease with Rachel/Numbuh 362.
 * The Stoic: He tries to be this when on the job, though he's much closer to Not So Stoic.
 * Sugar and Ice Personality: He tends to come across as overly serious, no-nonsense and aloof; but he's really a very kind person fully committed to justice and heroism.

 * Team Dad
 * What Does He See in Her?: Why the hell he is dating someone like Lizzie is lost on everyone, both In-Universe and out.

 * Improbable Piloting Skills
 * Loving a Shadow: His crush on Cree is pretty superficial, given he focuses on her beautiful appearance rather than her unpleasant personality.
 * Meaningful Name: Hoagie P. Gilligan Jr., appropriately enough, a twofer reference. First, there's "Gilligan," a reference to the title character of Gilligan's Island, who was also second-in-command on the S.S. Minnow. Then there's the "Jr.", often used at the end of a boy's name to signify that he's the second male in the family to have inherited his father's name (a seemingly throwaway detail that actually foreshadows the importance of his Disappeared Dad, Hoagie P. Gilligan, Sr.)
 * Must Make Her Laugh: Many of his awful puns are done to make Numbuh Five laugh (she's instead very annoyed).

 * Turn in Your Badge: He was once on Safety Patrol, but his reasons for leaving the force are unknown.

Numbuh Three / Kuki Sanban

""What do you think I am, an airhead or something?""

The team's medic, and the most feminine of the kids, a happy-go-lucky girl who loves Rainbow Monkeys. In battle, she specializes in diversionary tactics. She seems to have a lot of admirers, but her heart obviously belongs to a certain Aussie. Voiced by Lauren Tom.

 * Little Miss Badass
 * Living Emotional Crutch: To Numbuh Four.
 * Loose Lips

 * Single-Target Sexuality: Contrasting with her Dude Magnet status, she hasn't shown interest in anyone not named "Numbuh Four".

 * Spoiled Sweet: She's frequently shown to be pretty spoiled (especially regarding Rainbow Monkeys), but she's as sweet as they come.

 * Team Mom: To any animals she comes across.

 * Tomboy and Girly Girl: Girly Girl to Numbah Five's Tomboy.
 * Turns Out Like Her Mother: While its live action, her dress and mannerisms as an adult are the spitting image of her mother.

 * Wide-Eyed Idealist
 * Will They or Won't They?: With Numbuh Four, a lot.
 * Woman Scorned: Whenever Numbuh Four acts like a Jerkass (intentionally or not), expect this trope to happen.

Numbuh 4
Numbuh Four / Wallabee Beatles (Wally)

""Right, first I'll be cleaning your adult-lovin' prissy little clocks...""

The team's combat specialist. He's incredibly lacking in book smarts, but his combat prowess more than makes up for it. In his off time, he competes in adult disapproved sports. Despite his dislike for girly things, he very obviously has a crush on the very feminine Numbuh Three. Voiced by Dee Bradley Baker.


 * Anti-Hero: Type II or III.
 * Badbutt
 * Belligerent Sexual Tension: With Numbuh Three.
 * Berserk Button: You will not harm his baby brother or Numbuh Three in his presence. Also, don't make fun of his height or call him an idiot either.
 * The Big Guy: Despite being the shortest in the group.
 * Big Guy, Little Guy: The little to Numbah Two's big.
 * Blinding Bangs
 * Blood Knight
 * Boisterous Bruiser
 * Book Dumb: And proudly so, though.
 * Brains and Brawn: Brawn to Numbuh Two's Brains.
 * Bratty Half-Pint: At his worst.
 * Break the Haughty: Whenever he goes too far.
 * Butt Monkey
 * Cannot Spit It Out: His feelings towards Numbuh Three.
 * Crazy Jealous Guy: Towards Numbuh Three.
 * Crouching Moron, Hidden Badass
 * Cry Cute: Whenever he gets upset.
 * Cute Bruiser: Even more so than Numbuh 3, as he also appears to have Super Strength.
 * Drunk with Power: Became this after assuming team leader in "Operation: C.A.N.N.O.N"
 * Everyone Can See It: With Numbuh Three.
 * Four Is Death: As the aforementioned team's resident Blood Knight, he is the one who ends up in combat a lot. He tends to be the unluckiest member of the group, yet has his happy moments. In perspective, he is the only member of the KND to not suffer a Gender Bender (and manages to be the only male by the end of Operation F.U.T.U.R.E.) as well as
 * Good Is Not Nice: While a member of the KND, he can still be a bully befitting his age.
 * Gosh Darn It to Heck: His constant use of the word "Crud".
 * Happily Married:
 * Hair of Gold
 * Hair-Trigger Temper: Has a fuse as short as his height... and don't tell him that either.
 * Hero Worshipper: To Numbuh One.
 * Idiot Hero
 * Inferiority Superiority Complex: Frequently implied. He tries to act tough at all costs, but he's shown to be very sensitive to others' judgements and quick to jump into danger to prove himself (often with disastrous results). This is pretty evident with his crush on Numbuh Three: He acts like he doesn't care about her (or love in general), but turns into an insecure mess whenever there's any hint she would like other guys. His inability to confess his feelings is more likely to be because he can't believe a sweet girl like Kuki would be interested in someone like him, despite the all-surrounding evidence to the contrary.
 * Jerk with a Heart of Gold: Do not let his crass, rude, short-tempered demeanor fool you, he's still a brave warrior who will do anything for the people he loves, and is just as committed to the KND as the rest of his teammates.
 * Meaningful Name: Wallabee Beatles—four members of The Beatles [a.k.a "The Fab Four"]. Also, four is considered an unlucky number in Chinese culture and Wally is the unluckiest member of the group.
 * The Napoleon
 * Oblivious to Love: He fails to realize that Numbuh Three only has eyes for him, and is confused when she gets angry for saying love is gross and would never fall in love with anyone (the latter obviously being a lie).
 * Official Couple: With Numbuh Three, obviously.
 * Red Oni, Blue Oni: The red to Numbah Two's blue.
 * Ridiculously Successful Future Self/Hidden Depths: The Book Dumb kid grows up to.
 * She Is Not My Girlfriend: To Numbuh Three.
 * Single Man Seeks Good Woman: He loves Numbuh Three because of her being a cute, adorable sweetheart; as evident when he shows nothing but disgust at her Jerkass negative counterpart.
 * Super Drowning Skills: Can't swim, at least before "Operation: P.O.O.L.".
 * Why Did it Have to be Blood?: He's known to be hemophobic. He also dislikes water.
 * Will They or Won't They?: With Numbuh Three.
 * The Worf Effect: First to charge in, often the first to go down.

 * Action Girl: Especially when up against Cree.

 * Betty and Veronica: The Betty to her sister's Veronica for Hoagie's Archie.
 * Bifauxnen: Dressed up in a suit once for a dance.
 * Braids of Action
 * Broken Bird: A mild, preteen version. Given her traitorous evil sister, a haunting failure regarding Numbuh One, and her business with Heinrich; it's no surprise she has turned into such a Deadpan Snarker at her age.
 * But Not Too Foreign: She's half-French, even though both of her parents are black. Though it's likely her mom was raised in France.
 * Cain and Abel: The Abel to Cree's Cain.

 * Deadpan Snarker
 * Girl of Adventure: When she's candy hunting.

 * Noodle Incident: It's mentioned in passing in one episode that Numbuh Five was once leader of Sector V. She stepped down from the position after some incident, but we never find out. Other bits point that she couldn't take the stress of full on leadership. She
 * Not So Above It All: During a mission, Numbuh 4 stops to take some candies. Later, she tries to do the same.
 * Official Couple:
 * Opposites Attract:
 * Only Sane Employee: To Numbuh One.
 * Only Sane Girl: Though she can turn Not So Above It All.
 * Platonic Life Partners: With Numbuh One.
 * Positive Discrimination: The black girl is the coolest, the sanest, and quite often the smartest of the gang. Doesn't mean she doesn't have emotional baggage, though.
 * The Quiet One
 * Red Oni, Blue Oni: The blue to Numbah One's red.
 * Salt and Pepper: Pepper to Numbah Two's Salt.
 * Sassy Black Girl
 * Single Woman Seeks Good Man: As her interest in Maurice can attest.
 * Sugar and Ice Personality
 * Sweet Tooth: All the kids are, but only Numbuh Five would risk her life in search of legendary sweets.
 * Team Mom
 * Third Person Person: Not always, but very, very often.
 * Tomboy and Girly Girl: Tomboy to Numbah Three's Girly Girl. Subverted by their usual manner of dress: Kuki wears a sweater and sneakers, while Abby usually goes around in a minidress, white Mary Janes, and earrings.

Numbuh 86
Numbuh Eighty Six / Fanny Fulbright

""Of all the stupid things in the stupid world of stupid people acting stupid, you boys are the stupidliest! It's like you're trying to win a stupid contest but you're too stupid to take a stupidity test!""

The former Head of Decommissioning and current Global Tactics Officer. She's a shrill girl with a particular intolerance for the male sex. But due to her behavior, she has next to no friends. Voiced by Jennifer Hale.


 * Action Girl
 * Alpha Bitch: A military version.
 * Because You Were Nice to Me: After being betrayed by her friend Numbuh 12 and left devastated over it, Numbuh Three agrees to be her friend when nobody else would. As a result, she treats her far more nicely than she usually does (it helps they both adore Rainbow Monkeys)
 * Berserk Button: Saying anything anti-feminist around her is a big No-No.
 * Also, don't ever call her "Toots", as Numbuh 2 learned the hard way in "Operation: P.I.N.K.-E.Y.E."
 * Break the Haughty
 * Does Not Like Men: AND HOW!
 * Fiery Redhead: Bordering on Evil Redhead.
 * The Friend Nobody Likes: As the unpleasant decommissioning officer, nearly everyone hates her guts.
 * Jerkass: Later went from Straw Feminist to a just plain jerk to everyone. She becomes a Jerk with a Heart of Gold later on, though.
 * Little Miss Badass
 * Meaningful Name: Well, meaningful Numbuh, when you look at her rank: to be "eighty-sixed" is American slang for being thrown out, eliminated, or rejected (it's also used in restaurant lingo to mean that a menu item has run out and is no longer available)
 * The Medic: A flashback to Numbuh Five's second Mission shows 86 wearing hat with a cross and checking on the injured. How she went from a medic to head of decommissioning is not explained.
 * Never My Fault: Her introduction episode in which she never takes responsibility for her own blunders which wound up hampering Sector V's efforts for the mission. Thank karma kicked in when the spy she thought she she capture was actually an undercover agent (Number 362 in fact up) whose mission was ruined by 86 and get harshly chewed out for it (for added irony through out most of the episode she was putting down the boys in the group the most for any minor screw ups. End of the episode saw a girl doing this to her.)
 * Noodle Incident: According to a canon comic, whatever made her hate boys happened after she became an operative.
 * Slap Slap Kiss: With Numbuh Ninteenth Century.
 * Straw Feminist: Later became less of this and more flat-out unfriendly to everyone (which, oddly enough, was a step up for her)
 * Too Dumb to Live: She's really dedicated to her job so much so that it blinds her to the most obvious points of logic, such as in Operation E.N.D when she sent to capture and decommission Sector V based on the fact the computer says their turning 13. Numbuh One points out they're in the same age group, she and he even went to kindergardern together. But nope! If the databanks says their teens it must be true! No point in questioning it.
 * Tsundere: A G-rated Asuka, really.
 * Unexplained Accent: If she's the daughter of, where does her Irish accent come from? Apparently her mother, as revealed during her first slumber party (ever).
 * Unexplained Accent: If she's the daughter of, where does her Irish accent come from? Apparently her mother, as revealed during her first slumber party (ever).

Numbuh 362
Numbuh Three Sixty Two / Rachel T. McKenzie

""As Kids Next Door Soopreme Leader, I hearby order you to... go long!""

Originally the top spy in the KND, she is now its current Soopreme Leader.

 * Authority Equals Asskicking: As shown in "Operation: I.T." and "Operation: Z.E.R.O."

 * Dogged Nice Girl: Implied in regards to Numbuh One.

 * Idiot Ball
 * "The Grim Adventures of the KND" for Rule of Funny.
 * "Operation: Z.E.R.O." too, when the KND museum was under attack. Sector V was the closest. She ordered them to come back to the base which was also under attack but Nigel refuses till the museum was safe. Once Sector V did that as well as save the base single-handily, she chews out Nigel for disobeying orders. She does apologize later though once Grandfather is defeated, admitting if she had listened to him before the whole mess would've never happened.
 * I Just Want to Be Normal: In "Operation: I.T.". To be fair, in her world being normal means spending all day doing whatever you want in a giant treehouse and going on exciting missions.
 * Little Miss Badass
 * Meaningful Name: She's two numbers off from 360, a full circle. As in the KND revolves completely around her.
 * Mundane Made Awesome: Defeats Father by eating through a wall of broccoli. Though to be fair, broccoli does seem to be some kind of universal kryptonite in the show.
 * Nice Hat
 * Nice Girl
 * Reasonable Authority Figure
 * Ship Tease: With Numbuh One.

 * 0% Approval Rating: His sister is literally the only person who can tolerate his existence. The same goes for the audience.
 * Bad Boss
 * Berserk Button: Do not touch him. Ever.
 * Bratty Half-Pint: Big time.
 * Dirty Coward
 * Hates Being Touched: His number one weak spot.
 * Hate Sink: He's a selfish, ungrateful brat who treats his own sector and everyone around him like shit. He's such a special kind of prick he makes even the most hated characters in the show seem like absolute saints in comparison. Tellingly, he has absolutely no fans In-Universe and out, with only his sister being able to tolerate his presence.
 * Humiliation Conga: At the end of the finale, and deservingly so.
 * It's All About Me
 * Jerkass: So much so, he makes even Grandfather look pleasant by comparison.
 * Screw the Rules, I Have Connections: He thinks being the Soopreme Leader's younger brother means he can get away with anything he does, no matter how dickish or horrible, to the point Numbuhs One and Four had to be restrained because of this.
 * Sibling Yin-Yang: With his sister.

Father
Father

""Bravo, Mr. Uno. You managed to skillfully outwit a bunch of children. The question is, do you have what it takes to play with the big boys?""

The mysterious head villain, Father is a man who wears a suit of shadows and is skilled in very dark powers. He schemes to enslave all children and turn them into his twisted version of "delightful". But despite his dark and malicious appearance, sometimes all he wants to do is curl up in a bathrobe with some Rocky Road. He is voiced by Maurice LaMarche.


 * Affably Evil: To the point of being Adorkable at his goofiest.
 * Alas, Poor Villain: Despite how evil he has been, it's hard not to feel bad for him when Grandfather treats him like shit, especially considering he's the reason why he turned evil in the first place.
 * Arch Enemy: To the Kids Next Door in general and Numbuh One in particular.
 * Awesome McCoolname:
 * Big Bad: Alternates with Mr. Boss depending on the focus.
 * Break the Haughty
 * Burning with Anger: Not just Wreathed in Flames, but they increase in intensity when angry.
 * Cain and Abel:
 * Card-Carrying Villain
 * Child-Hater
 * Clothes Make the Superman: Probably a power inherited from Grandfather (it's never really explained), but the shadow look is actually cover giving him his powers and intimidating nature. The one time its taken off, we see the real Father (and
 * Cloudcuckoolander: Kinda becomes this through Villain Decay.
 * Diabolical Mastermind
 * Dirty Coward:
 * Disproportionate Retribution: In the finale, he wants to kill Numbuh One for stealing his pipe.
 * Enemy Mine: With the KND in "Operation: Z.E.R.O."
 * Even Evil Has Loved Ones: He has screwed-up relationships with his dad, his nephew and his children, but the only person he seems to genuinely care for is his older brother,, despite his jealousy over him being the favourite. This makes sense, as his brother is pretty much the only person who has shown genuine love and respect towards him, as opposed to the above three.
 * Evil Is Burning Hot: Is it ever.
 * Evil Uncle:
 * Freudian Excuse:
 * Glowing Eyes of Doom
 * Green-Eyed Monster: Towards his older brother, . With good reason.
 * Hair-Trigger Temper: Through Flanderization.
 * Hates Being Touched
 * Humanoid Abomination: Can be seen as this.
 * Inferiority Superiority Complex: The reason for his gleeful villainy is to compensate for the many, many insecurities he carries over due to him being abused by his evil father. This is shown explicitly in The Movie.
 * Luke, I Am Your Father:
 * Large Ham: You can tell Maurice LaMarche is having way too much fun with this role.
 * The Man Behind the Man: In the earlier episodes, the Delightful Children were the main villains, though he was actually mentioned in the first episode. In "Operation: C.A.N.N.O.N." the Delightfuls mention a curfew alert stating that they had to leave their butt whupping on Sector V or else Father would be angry.
 * Meaningful Name:
 * Moral Myopia: Has experienced child abuse from his father, yet is perfectly fine with bullying kids during his grown up years. He could be some kind of Troubled Abuser.
 * Name's the Same: No, he's not the Big Bad from Fullmetal Alchemist, although their roles in their respective series are surprisingly similar.
 * No Celebrities Were Harmed: His voice is a parody of Kirk Douglas, which LaMarche previously used on Animaniacs.
 * One-Winged Angel/Scaled Up: In "Operation: I.N.T.E.R.V.I.E.W.S.". He turns into a dragon. Somehow.
 * Playing with Fire: Gets it from his dad.
 * Sinister Silhouettes
 * The Unfavorite: Grandfather favored over him, mostly because Father was too spineless to stand up for himself.
 * Tragic Villain: He has suffered horrendous Parental Abuse at the hands of his more evil father (who still doesn't have any respect towards him). At the end of the day, behind his evil exterior, he's actually a sad, miserable man who tries to make others miserable to feel better about himself.
 * The Unfavourite: He's this to Grandfather, being treated like absolute shit while he sings his praises towards his older brother,
 * Used to Be a Sweet Kid
 * Vile Villain Saccharine Show: At least at first.
 * Villains Out Shopping
 * Xanatos Gambit
 * "Well Done, Son" Guy: To his father, Grandfather.
 * Woobie, Destroyer of Worlds

The Delightful Children from Down the Lane
The Delightful Children from Down the Lane

""Hello Kids Next Door. Perhaps you would like to try kicking our posteriors now?""

Father's eerie children, supposedly an adult's view of the "perfect" kids. They are educated, well-dressed and polite, but are somewhat uncivilized in their burning hatred for the Kids Next Door. They always appear clustered together, move as one and speak in perfect unison. They are voiced by Benjamin Diskin, Dee Bradley Baker, and Cree Summer.


 * Adorably Precocious Child: Bruce (Short blonde kid).
 * Anti-Hero: Type V.

 * The Dragons
 * Enemy Mine: With the KND in "Operation: Z.E.R.O.".
 * And to a lesser extent "Operation: Z.O.O.".

 * Evil Counterpart: To Sector V.
 * Eye Glasses: Constance/Ogie has these.
 * The Faceless / Never Bareheaded: Lenny (top right). Subverted in that he eventually does show his face In "Operation: U.N.D.E.R.C.O.V.E.R.".
 * Famous Last Words: As in The Movie: "Tell...The Kids Next Door...That we miss them!"
 * Fan Nickname: Ashley and Ogie (The two unnamed girls of the group.)
 * Flanderization
 * Hates Being Touched
 * Hive Mind/I Am Legion: They talk and act as if they are just one person instead of five.
 * Jerkasses: Despite their image as "perfect children", they're sadistic and cruel to everyone else of their own kind, particularly whenever it's their birthday where they never share their cake with other kids and flaunt it.
 * Kids Are Cruel: And HOW!
 * Light Blue Eyes Take Warning
 * Light Is Not Good
 * Mind Control Eyes: Light Blue.
 * Naughty Is Good
 * No Name Given: Only two girls are unnamed.
 * One-Winged Angel: In "The Grim Adventures of the KND", as the Delightful Reaper.
 * The Psycho Rangers: They look eerily similar to sector V.

Chad Dickson
Chad Dickson / formerly Numbuh Two Seventy-Four

""There was no way I was going to turn over everything I ever built, everything I ever worked for, to a bunch of snot-nosed kids!""

Former Soopreme Leader of the Kids Next Door idolized and loved by all, he turned evil the moment he turned thirteen. He then served as a high-ranking member of the Teen Ninjas, and lost all the respect he had to his name. Generally cocky and approving of himself, both before and after his betrayal. Voiced by Jason Harris.


 * Always Second Best: To Nigel, and he's not at all happy about it.
 * Becoming the Mask: Sort of.
 * Badass Normal
 * Berserk Button: Anything that threatens his position as the best KND agent, which turns out to be Nigel himself.
 * Big Brother Mentor: Was this when he was still Numbuh 274.
 * Blond Guys Are Evil: Or at least huge pricks.
 * Broken Ace: Is he ever.
 * Broken Pedestal: A brutal one.
 * Card-Carrying Villain:
 * Child-Hater
 * Driven by Envy: His rivalry with Nigel is essentially fueled by this.
 * Evil Is Dumb: After he turns evil, he automatically loses competence.
 * Face Heel Turn:
 * Fallen Hero
 * Glory Seeker/Glory Hound
 * Hoist by His Own Petard: During Nigel's training days, Chad showed him a move that left Nigel flat on his back.
 * Inferiority Superiority Complex: His Fatal Flaw. He has a pathological desire to be the best, and there was a time when he indeed was considered such. Then Nigel had to unintentionally surpass him, and given his self-worth depended on him being the absolute best, this led to him despising Nigel and doing everything he could to reclaim his title as the best warrior in order to prove himself.
 * It's All About Me
 * Jerkass: The "Dick" in his surname isn't just for show.
 * Jerk with a Heart of Jerk: In "T.R.E.A.T.Y". It has to be seen to be believed.
 * Lamarck Was Right: His parents are Destructo Dad and Mega Mom, and later becomes a more recurring threat than they ever were.
 * Not So Different: He has a lot in common with Cree, as seen on this page.
 * Pride: He thinks he's still the best there is.
 * The Resenter: To Nigel.
 * Shadow Archetype: He's this trope to, oddly enough, Wally/Numbuh Four. Both are tough warriors who try to constantly prove themselves to satisfy their own Inferiority Superiority Complexes, and are shown to be jealous of Nigel/Numbuh One due to his talents as a fighter and leader. The difference is that Wally genuinely respects and cherishes his friendship with Nigel and puts his ego aside for his sake, while Chad lets this resentment take over him and puts his own desires over anything else.
 * Teens Are Monsters
 * Took a Level in Jerkass: To the point he could be considered worse than Cree in this regard, which is no small feat.
 * Villainous Breakdown:
 * Villainous Crossdresser: In "Operation: S.L.U.M.B.E.R.".
 * Took a Level in Jerkass: To the point he could be considered worse than Cree in this regard, which is no small feat.

 * Villainous Crossdresser: In "Operation: S.L.U.M.B.E.R.".

Cree Lincoln
Cree Lincoln/ formerly Numbuh Eleven

Numbuh Five's older sister and former Kids Next Door operative, skilled, cool and determined. Her relationship with her sister is very strained, but deep down they really do love each other. She is a high ranking member of the Teen Ninjas and Father's apprentice. Voiced by Cree Summer.


 * Action Girl
 * Badass Normal
 * Bare Your Midriff
 * Betty and Veronica: The Veronica to her sister's Betty to Hoagie's Archie.
 * Big Sister Bully: She's one of the worst examples of this trope ever.
 * Big Sister Mentor/Cool Big Sis: When she was still in the KND. Now, while such moments are very rare, Cree has shown that she's not totally uncaring toward Abby.
 * Broken Pedestal: Towards Abby.
 * Cain and Abel: The Cain to Numbuh Five's Abel.
 * Card-Carrying Villain
 * Child-Hater
 * The Danza
 * Dark Action Girl
 * Even Evil Has Loved Ones: Zig-zagged. She may show some kindness towards Abby, but that doesn't stop her for treating her like shit. And considering the mayority of the villains treating their loved ones (even if they're heroic) with way more respect and care, she comes across as worse than them in this regard. See YMMV's Unintentionally Unsympathetic.
 * Face Heel Turn
 * Fallen Hero
 * Instant Armor
 * It's All About Me
 * Jerk with a Heart of Jerk: Sure, she may have her nice moments with her younger sister, but she's not above being an Ungrateful Bitch who treats her horribly. And while she does want to reconcile with her, she does want to do so by forcing Abby into a Face Heel Turn proving that, even if she cares about Abby, she cares more about herself, not willing to make any effort into repairing their relationship (that she destroyed in the first place).
 * Kick the Dog: As being a bitch towards her sister wasn't enough, she tends to be horrible towards Numbuh Two, who has a crush on her, especially in "Operation: K.I.S.S.".
 * Not So Different: From Mushi, as they're both the evil, treacherous and ungrateful sisters of the two female protagonists of the series. She's also this with Chad.
 * Ship Tease: With Maurice.
 * Teens Are Monsters
 * Ungrateful Bitch: YES. This is one of the many reasons she's largely despised by the fandom.

Mr. Boss
Mr. Boss

""So long, shrimp! I hope your friend likes Pluto!""

CEO of a big company and additionally the "leader" of the villains, he tends to lead them on cooperative missions. He hates all children... except his own. Voiced by Jeff Bennett.


 * Big Bad: Alternates with Father on this position.
 * Card-Carrying Villain
 * Child-Hater
 * Corrupt Corporate Executive
 * Even Evil Has Loved Ones: He does love his children, and would never harm them, which from a Child-Hater like him, this means a lot.
 * Everyone Calls Him "Barkeep": "Operation: D.A.D.D.Y." reveals his last name to be, so his villain name only shows his position.
 * Evil Parents Want Good Kids
 * Good Smoking, Evil Smoking
 * Hidden Heart of Gold: "Gold" may be stretching it, but he does show himself to be a caring, devoted father to his own children (who are KND operatives, by the way) He has shown some moments of camaraderie with other villains as well (even Toiletnator)
 * Moral Myopia: He hates kids unless they happen to be his.
 * Pet the Dog: He does love his own children.
 * Usually, he's the most adamant in treating Toiletnator like crap, but in "M.I.S.S.I.O.N", after Toiletnator offers himself to fight the KND while he and the other villains deal with the bowling match, he sincerely thanks him for it, even calling him by his real name, Lou. Toiletnator's reaction is pretty obvious.

Toiletnator
Toiletnator

""Kids Next Door, prepare to be flushed!""

The show's most pathetic villain. He gets no respect from the Kids Next Door or his fellow villains. Voiced by Dee Bradley Baker.


 * Adorkable
 * Affably Evil: For a given value of "evil", anyway.
 * Always Identical Twins:
 * Anti-Villain: Types II/IV.
 * Awesome McCoolname
 * Butt Monkey: To the point Pre-Crisis Doctor Light and Heinz Doofenshmirtz could kick his ass.
 * Cain and Abel: Completely averted.
 * Card-Carrying Villain
 * Child-Hater
 * Cloudcuckoolander
 * Crouching Moron, Hidden Badass: He's show several signs of this through the series. Idiot though he may be, this does still apply.
 * "Operation F.L.U.S.H."—He takes out five other villains thinking they're KND operatives in disguise. Of course, the five villains in question had just successfully taken over the Sector V treehouse, and then Numbuhs 1-5 (The actual members of Sector V who have been all excused from school early) show up and kick his butt.
 * Evil Uncle:
 * Evil Twin:
 * The Friend Nobody Likes: He's hated by other villains due to his incompetence and tendency to screw-up their plans.
 * Friendly Enemy: He was friends with Numbuh Four for awhile ("Operation M.O.V.I.E."), and joined the announcers in the finale. Though, in the CM/HB example he referred to Numbuh Four (actually Nightbrace) as his arch-nemesis. Gets kinda weird when it's revealed in a canon comic that
 * Granola Guy: Likes vegetables, hates meat.
 * Harmless Villain: He's called the Toiletnator, for crying out loud!
 * Ineffectual Sympathetic Villain: Very ineffectual, very sympathetic. Except when he is kind of effective.
 * Jerkass Facade: An hilariously flimsy one.
 * The Millstone: To the villains. Oh, so much.
 * Not-So-Harmless Villain
 * He comes up with a plan in "Operation: M.O.V.I.E.S." that impresses the other villains. Too bad Numbuh Four heard it first.
 * He also managed to "flush" the entire Grand Canyon after the KND filled it with cereal and milk.
 * Throw the Dog a Bone/Yank the Dog's Chain
 * Toilet Humor: Played with. This is a kids' show, so it's used only in the most literal sense.
 * Undying Loyalty: To Mr. Boss, as he states in "M.I.S.S.I.O.N".
 * Villain Episode: "Operation: F.L.U.S.H."
 * Villains Out Shopping
 * "Well Done, Son" Guy: It becomes very clear his motive for being a villain is to get respect from others, especially Mr. Boss. He almost never gets it.
 * What Kind of Lame Power Is Heart, Anyway?: His motif is questionable. It also seems he's got some psychic control over flushing.
 * Heart Is an Awesome Power: Invoked. See the entries on Crouching Moron, Hidden Badass and Not-So-Harmless Villain. It doesn't seem so much that his powers are useless, he's just normally too short-sighted to use them correctly.

Stickybeard
Stickybeard

A spirited candy pirate who loots and plunders candy from neighborhood children. He respects Numbuh Five and seeks her as an apprentice. Voiced by Mark Hamill.


 * Badass Beard
 * Badass Normal: Among few villains that don't have superpowers, he even beat the crap out of Father twice in a round
 * Captain Color Beard: Or Adjective-beard.
 * Card-Carrying Villain
 * Enemy Mine: With Numbuh Five, against Black John Licorice.
 * Eternally Pearly-White Teeth: Subverted, his teeth are incredibly rotten from all the candy.
 * Even Evil Has Standards: He refuses to allow the Great White Asparagus to eat Sector V. While that was more of a The Only One Allowed to Defeat You moment than anything else, he generally does seem to have some degree of honor.
 * Friendly Enemy: With Numbuh Five.
 * Hidden Heart of Gold
 * Hook Hand: With a candy cane instead of a hook.
 * Noble Demon
 * Pirate
 * Serious Business: Candy stealing is his prime modus operandi. Get in the way of that, and you're good as dead. And also being told if he was "sugar-free".
 * Talk Like a Pirate: Of course, since he's an odd Expy of Blackbeard.
 * Villains Out Shopping: He's helped Numbuh Five in one episode.
 * We Can Rule Together: To Numbuh Five. It almost succeeded until she remembered her friends, but now it leads to below.
 * Worthy Opponent: To Numbuh Five.

""Ach, lipschen, I say so many things I do not mean. Like, ah, no more candy for me, or, who would like some of my lollipops!""

A former friend of Numbuh Five and current candy-hunting rival. He greedily seeks forbidden candy regardless of the consequences. Voiced by Dee Bradley Baker / Candi Milo.


 * Arch Enemy: To Numbuh Five.
 * Beauty Equals Goodness:
 * Brought Down to Normal: Got turned into a chocolate monster that can turn anything he touches into chocolate. After Numbuh Five defeats him, the KND turns him back to normal.
 * Card-Carrying Villain
 * : In sacrificing his, he
 * Greed: Obsessed with getting candy and never sharing it, which usually leads to many of his downfalls.
 * Homage: To Indiana Jones Nazi villains.
 * I Lied: As his quote indicates.
 * My Name Is Not Durwood: Numbuh Five calls him "Heinie".
 * Never My Fault: He does this a lot, such as in his first appearance where he blames Abby for tainting the candy with the taste of asparagus when she warned him before hand that being greedy will put that curse into effect. It's also
 * One-Winged Angel: In his first appearance after obtaining a jewel, he transforms into a monster with power of candy. Numbuh Five defeats him though. After falling into a chocolate volcano, he returned as a powerful monster who can turn things into chocolate by touching it. He was cured by the KND though.
 * Noodle Incident: Throughout the series he remains angry at Numbuh Five for "Guatemala". His last appearance reveals that
 * Roaring Rampage of Revenge: When he returns after falling into a chocolate volcano, having been turned into a chocolate monster.
 * Serious Business: Like with Stickybeard, Candy is serious business.
 * Took a Level in Kindness:
 * Serious Business: Like with Stickybeard, Candy is serious business.
 * Took a Level in Kindness:

Mushi Sanban
Mushi Sanban

She's Numbuh Three's little sister. At first seen as just an annoying brat, she eventually establishes herself as an evil kid who outright despises her much kinder sister.


 * Annoying Younger Sibling: She appeared to be one at first, only to turn out to be much worse than that.
 * Arch Enemy: To Numbuh Two.
 * Big Sister Worship: Subverted. She seems to be this at first, only to reveal she absolutely despises her sister.
 * Bitch in Sheep's Clothing: If you thought she was just a younger version of her sister, you'd be dead wrong.
 * Bratty Half-Pint
 * Cain and Abel: The Cain to Numbuh Three's Abel.
 * Cute and Psycho: Even worse than her sister.
 * Driven by Envy: Her rivalry with her sister is a result of this.
 * Enfante Terrible
 * Even Evil Has Loved Ones: Her love for King Sandy is very genuine, as well as her love for her parents (which may have sparked her rivalry with her sister in the first place)
 * Evil Is Petty: She destroyed her sister's Posh Party Rainbow Monkey out of spite. Even Cree wasn't nearly as petty.
 * Freudian Excuse: It doesn't excuse anything she does, but her hatred for her sister seems to stem from the feeling her parents tend to spoil her sister more than her.
 * Girlish Pigtails
 * Love Makes You Evil: Ever since she started dating King Sandy, she became a villain (though she was definitely bratty beforehand)
 * Not So Different: From Cree, being both traitorous, ungrateful jerks towards their heroic sisters.
 * Unholy Matrimony: With King Sandy.

Grandfather
Grandfather

Father 's father and an Evil Overlord who once ruled the entire planet. He's by far the most dangerous enemy the KND have every faced and makes Father look like a saint compared to him. Acted as the Big Bad in The Movie. Voiced by Neil Ross.


 * Abusive Parent: He's why Father is the way he is. Let that sink for a moment.
 * Berserk Button: Don't be a coward in his presence.
 * Big Bad: Of The Movie.
 * Blue and Orange Morality: While gleefully evil, he shows a very bizarre code of morality, showing respect only to those who rebel against him and despising cowards, barely caring if the person is good or evil.
 * Card-Carrying Villain: The first thing he says after being reawakened is to thank Father for "reawakening the pure evil" laying dormant within him.
 * Eldritch Abomination
 * Even Evil Has Loved Ones: His fondness for his eldest son is shown to be genuine, as he was shown to be disappointed with his non-evil life and still kept him in his will despite (or perhaps because of) his rebellion against him. Granted, he still fights him when necessary, but this is as close to a redeeming trait he has. Averted with his youngest son, though, whom he hates.
 * Even Evil Has Standards: Due to his Blue and Orange Morality, he really, really hates cowards. It's even the reason for his Parental Favoritism.
 * Evil Parents Want Good Kids: Played with. He does try to persuade to defect to his side, and is saddened when he refused. However, even when fighting him, he still cares for him (in his own bizarre way)
 * Evil Overlord: Once ruled the world with an iron fist before Numbuh Zero betrayed and defeated him.
 * Eviler Than Thou: To literally every villain in the Rogues Gallery once they find out his plan to turn everyone that's ever been a kid into Senor Citizombies includes them. Father actually outright states that Grandfather is eviler than him before reviving him, calling him "The World's Most Ultimate Evil".
 * Expy: He seems to be partially based on Aku from Samurai Jack—a black, shadowy monster who stands a couple stories tall in his natural state, can manipulate fire, has a pretty screwed-up morality code, and his very awakening pretty much spells doom for the whole world.
 * Fisher King: When he rules the world, he uses his Reality Warper abilities to convert into an old-style Crapsack World complete with child labor, Industral Era-style factories making tapioca pudding for him to eat.
 * Genre Savvy: Is smart enough to NOT underestimate Hope Springs Eternal and understands he hasn't really won until he's destroyed the Book of KND, which let Numbuh Zero defeat him the last time. And he also doesn't go out to find it until nearly the entire world is under his control and the Kids Next Door are all but destroyed.
 * Humanoid Abomination
 * Irony: His relationships with his sons in a nutshell. He loves and dotes on his oldest son, who rebelled against him and wants nothing to do with him; yet he despises his youngest son Father, who followed in his footsteps and desperately wants his approval.
 * Knight of Cerebus
 * Large Ham: Is an even bigger ham than his son.
 * Laser-Guided Amnesia: Literally. Had his memory erased by Numbuh Zero using some kind of laser, reducing him to a harmless old man until he's "recommissioned" by Father. This actually seems to be the only way to defeat him, as all other attempts failed completely.
 * Morality Pet: Played with. seems to be this, as he does like him as his son and considers him the favorite... but then tries to incinerate him when he turns on him without blinking an eye. That said, he still liked  for the fact he was willing to stand up to him and give Grandfather something of a challenge, and before being decommissioned, he still has  in his will.
 * Nigh Invulnerability: His reaction to getting crushed under the entire Kids Next Door Moonbase is to dust himself off and ask if they really thought that would work.
 * No Ontological Inertia: His defeat restores the world to normal.
 * Physical God: He's the single strongest villain in the series and is capable of surviving a direct hit from a Colony Drop without even a scratch. He can also 'age' the entire world at will.
 * Playing with Fire: Father gets it from him.
 * Rapid Aging: His primary ability is to age everything he touches, though not only does he age them rapidly, he turns them into his 'Senor Citizombie' minions.
 * Reality Warper: He's capable of changing the world as he sees fit, normally to a more "old time" look.
 * Social Darwinist
 * Super-Powered Evil Side: His human form is a harmless old man so long as his memories aren't restored.
 * Trademark Favorite Food: Tapioca pudding, so much so that was one of the reasons he wanted to rule the earth.
 * Transformation Sequence: Unlike Father, who just grows his "shadow suit" back, Grandfather sucks in the shadows from everything in the room to form his after being reawakened in a much more elaborate fashion.
 * Ungrateful Bastard: To Father, to the point you can't help but feel sorry for the guy.
 * The Virus
 * Vile Villain Saccharine Show
 * You Got Spunk: The reason for his Parental Favoritism.
 * Citizombie Apocalypse

Lizzie
Elizabeth Devine (Lizzie)

Numbuh One's demanding girlfriend. While she's quite clingy, she does genuinely care for Nigel, but his work for the Kids Next Door strains their relationship. Voiced by Grey DeLisle.


 * Badass Normal: Bonus points for not even being a KND Operative.
 * Betty and Veronica: Technically, she's the Betty to Rachel's Veronica, but she has more of a Veronica personality.
 * Bitch in Sheep's Clothing: More downplayed than the fandom thinks, but there's definitely a manipulative, short-tempered, controlling streak behind her sweet, Girl Next Door exterior.
 * Characterization Marches On: In her first appearance, she brainwashed Nigel into being her obediant boyfriend and even tried to make him destroy to his friends. The KND fight back and Nigel is unbrainwashed, but the episode ends with Lizzie getting the date she wanted anyway. Later episodes more or less completely ignored her origin story, and considerably softened her character.
 * Clingy Jealous Girl
 * Day in The Limelight: "Operation: L.U.N.C.H."
 * Easily Forgiven: Apparently Nigel and the rest of Sector V had no hard feelings over the little matter of her having originally tried to Brainwash him, though it's mostly just Numbuh One and Numbuh Three. Numbuh Two and Four openly dislike her, dreading any contact with her at all. They just don't verbalize it much due to fearing her bad temper (well, at least Numbuh Two fears her temper). Numbuh Five is tolerant of her at best.
 * Girl Next Door: Puns aside, she has the appearance of one. Keyword being "appearance".
 * Eye Glasses
 * The Friend Nobody Likes: About the only ones in Sector V who honestly like her are Numbuh One (her boyfriend) and Numbuh Three. Numbuhs Two and Four can't stand her, while Numbuh Five is at best tolerant.
 * I Want My Beloved to Be Happy:
 * Jerkass Has a Point: There are times her short fuse isn't entirely unwarranted, mostly concerning Nigel's Workaholic behavior.
 * Jerk with a Heart of Gold: She's controlling, short-tempered and obsessive, but she can be kind to others and genuinely loves Nigel.
 * Lethal Chef: If your food seriously knocks out Numbuh Two, you more than qualify for this trope.
 * Let's Get Dangerous: When she's properly motivated (either by Numbuh One being in danger or her plans being interrupted one too many times), she's a mecha-commandeering force to be reckoned with.
 * The Load: On occasion.
 * Mood Swinger
 * Official Couple: Her and Numbuh One.
 * Opposites Attract: With Nigel.
 * Palette Swap: She has the same character model as one of the Delightful Children From Down The Lane.
 * Single Woman Seeks Good Man: She's Nigel/Numbuh One's girlfriend.
 * Tsundere: Oh, yes, sometimes dipping into Yandere'ish tendencies in her more extreme moods.
 * Woman Scorned: At worst.

Tommy Gilligan
Tommy Gilligan (The Tommy)

Numbuh Two's little brother, Tommy is an excitable child ready to fight adult tyranny. Unfortunatly, circumstances effectivly halted his KND career. He now fights solo as "The Tommy". Voiced by Dee Bradley Baker.

"Numbuh Five: "I work alone! I am The Tommy!" He is definitely your brother, Numbuh Two."
 * Adorkable
 * Big Brother Worship: They may have something of a rivalry, but it's clear Tommy idolizes his older brother and wants to be a hero like him.
 * Broken Streak: In "Operation: C.A.K.E.D.-F.O.U.R." he breaks his family's Tube-A-Thon losing streak (Despite his brother coming in 2nd).
 * The Cowl: Well, he tries to be at least.
 * A Day in the Limelight: "Operation: D.U.C.K.Y.".
 * Disappeared Dad
 * Dude, Where's My Reward?: In "Operation: G.R.A.D.U.A.T.E.S.".
 * Hates Baths
 * Heroic Sacrifice: In "Operation: G.R.A.D.U.A.T.E.S.".
 * Heroic Wannabe
 * I Work Alone: After becoming "The Tommy".
 * Keet: Ties in with his Large Ham status, as he is a lot more hyper and enthusiastic than his brother.
 * Large Ham: Once he becomes "The Tommy", he becomes considerably hammier.


 * Lower Deck Episode: "Operation: T.R.A.I.N.I.N.G.".
 * Nice Guy: Flaws aside, he's just as sweet and kind as his older brother.
 * Sixth Column
 * Spell My Name with a "The": He calls himself The Tommy, though he's about the only one.
 * Straw Loser: Not "Loser" per se, but he's such an oddball it makes Numbuh Two look like the Only Sane Man by comparison.
 * Tagalong Kid
 * You Are Number Six: Played with; He takes the title of Numbuh T during his brief tenure with the KND.
