The main characters of the show, they are a division of a worldwide actually galactic organization known as the Kids Next Door. They are considered to be one of the best teams in the KND.
2×4 Technology: What most of their equipment is made of.
Badass Normal: By comparison with most of the villains anyway, as they rely mainly on the aforementioned Bamboo Technology and their military training in combat.
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.
Only Child Syndrome: Nigel is the only Sector V member who doesn't have any brothers or sisters.
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".
The team's technology expert who loves cracking bad jokes. As Sector V's technology officer, he designs many of the 2×4 technology the team uses In his off time he enjoys building and flying airplanes and solving mysteries at his school. Voiced by Benjamin Diskin.
Goggles Do Nothing: Half and half, he works with high speed equipment so it would help with wind resistance. But generally just has them on most of the time for no reason either.
Happily Married: To Numbuh 5 of all people as adults. True what they say about opposites attracting, eh?
He's All Grown Up: Teen!Hoagie is pretty cute (not to mention much thinner), and even manages to catch Cree's attention.
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.)
"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.
Flanderization: Her love for Rainbow Monkeys grew to ridiculous proportions as the series went on. So much so that it even saved the universe at one point.
Mama Bear: Do not mess with the hamsters or Bradley.
Meaningful Name: Kuki Sanban — "Sanban" is Japanese for "third"; Kuki is a misspelling of "kooky" (meaning crazy or off-kilter) and refers to her ditzy, Cloudcuckoolander personality.
"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. Voiced by Dee Bradley Baker.
Berserk Button: You will not harm his baby brother or Numbuh Three in his presence. And, while he's not as bad about it as another vertically-challenged blond, don't make fun of his height, and don't call him an idiot either.
The Big Guy: Despite being the shortest in the group.
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 marrying the girl of his dreams.
Good Is Not Nice: While a member of the KND, he can still be a bully befitting his age.
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 Worf Effect: First to charge in, often the first to go down.
Numbuh 5
Numbuh Five / Abigail Lincoln (Abby)
"I like it when things are too easy."
The team's second-in-command, she's the one that keeps a level head under all circumstances, even when everyone else loses it. In her spare time, she's a candy hunter, which brings her in conflict with her rival Heinrich and candy pirate Stickybeard. Voiced by Cree Summer.
Enforced Cold War: With Cree; both of them have to keep up the act of two loving sisters at home while pointing lasers at each other beneath the dinner table.
Meaningful Name: Abigail Lincoln — has the same initials and last name as U.S. President Abraham Lincoln (A.L.), whose face is on the five dollar bill in American currency.
Numbuh Five: The last time Numbuh Five didn't help someone kidnapped by the Delightful Children, they did something she can't ever forgive! Numbuh Four: What?! What did they do that was so bad?! Numbuh One: ... They made me bald.
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 nearly has a panic attack when Nigel reinstates her as leader before he leaves for his galactic mission. He reassures her she always had what it took to lead the group. Considering she would later take over the role of commanding the entire K.N.D, he wasn't kidding
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 Six / BradleyA skunk that Numbuhs Two and Three took under their wing since "Operation: C.A.M.P.". After foiling Chester's plan of making a work camp out of an actual kid's camp, he is inducted into the Kids Next Door as an honorary member. After getting critically injured by Cree, Numbuh Two upgrades him into half-skunk, half-robot R.O.B.O.-B.R.A.D.L.E.Y. in "Operation: H.O.S.P.I.T.A.L.". He is voiced by Dee Bradley Baker.
"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.
Daddy's Little Villain: She's Mr. Boss' (who leads the bad guys) daughter, but she in turn is still one of the good guys' leaders. Does explain a lot though.
Getting Crap Past the Radar / Stealth Pun: During "Operation: G.R.A.D.U.A.T.E.S." she was turned into a dog, resulting in a muttering of "Well that figures..." — because she's a bitch, that's why.
Her name in the UK is a bit obscene too (see Meaningful Name below)
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)
Her first name is also meaningful, at least in the UK and Ireland where she is from. In the UK, "fanny" is a vulgar slang term for the female genitalia, another slang term for that part of the the body is "cunt" . "Cunt," in both UK and US slang, is also used to mean someone who is unpleasant (it's stronger than "bitch"), so combining that with Fanny's personality, and you have a Meaningful Name that somehow got past the censors -- at least the ones in the UK (in American English, "fanny" is one of many slang terms for the human buttocks and isn't considered obscene at all. Funny and a tad improper — yes, but not obscene).
If you're willing to think deeper than her name could be meaningful in the US too. Another slang term for your butt is "ass", and that's even more commonly used to refer to an unpleasant person (similar to "bitch", once again).
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.
Straw Feminist: Later became less of this and more flat-out unfriendly to everyone.
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.
Unexplained Accent: If she's the daughter of Mr. Boss, 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. Due to her busy and demanding job, she's often stressed, but at heart she stands stubbornly for the rights of kids everywhere, and if the situation arises she can be fun-loving too. Has grown to form a close friendship with Nigel Uno. Voiced by Rachael MacFarlane.
"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.
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.
"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.
Clothes Make the Superman: Proabaly a power inherited from Grandfather (its never really explain) 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 he's surprisingly rather nerdy looking.
Freudian Excuse: Grandfather makes him look like a saint and the reason he refused to help fight him wasn't out of evil but out of pure fear. Grandfather also liked his brother better than him and treated him like crap. We also see Father break down and curl up on the floor when threatened to be forcefed broccoli because Grandfather did it to him in such a way he was traumatized for life!
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: His real name comes from real life figure Benedict Arnold who was best known as a traitor to the U.S during the Revolutionary War. As shown in the movie, when given the chance to fight against Grandfather alongside Numbuh Zero, B. Uno was too scared to do so and exits, not once but twice.
Moral Myopia: Has own experiences of child abuse from his father, yet is perfectly fine with bullying kids during his grown up years.
The Delightful Children from Down the Lane/ Sector Z
"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.
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.
"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.
Becoming the Mask: Sort of. He is actually faking treachery and is a secret teen operative for the KND... however, after many defeats, his hatred for Numbuh One becomes real and he actually tries to kill him in his final appearance in the show.
Fake Defector: Revealed in "Operation: T.R.E.A.T.Y.", though, as evidenced by his Villainous Breakdown, he genuinely does have a lot of negative qualities.
Good Is Not Nice: He was nice when he was Soopreme Commander, when he showed he was a deep cover agent, his jealousy still made him act like a nasty tool.
Hoist by His Own Petard: During Nigel's training days, Chad showed him a move that left Nigel flat on his back. In his final battle against Numbuh 1, Nigel uses the same move to beat him.
Lamarck Was Right: His parents are Destructo Dad and Mega Mom, and later becomes a more recurring threat than they ever were.
Cree Lincoln/ formerly Numbuh ElevenNumbuh 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.
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.
"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.
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. What an Idiot.
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 he's Numbuh Four's uncle.
StickybeardA 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.
Even Evil Has Standards: He refuses to allow the Great White Asparagus to eat Sector V. Though that was more of a The Only One Allowed to Defeat You moment than anything else. Though over all, he does seem to have some degree of honor.
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".
"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.
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.
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 his grudge for the Guatemala Incident as after he sacrificed his beauty due to yet another curse. He once more blamed Abby for not stopping him from eating his caramels and supposedly leaving him stuck in that state. Turns out she was trying to find a way to break the curse.
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 apperance reveals that he performed a ritual to get delicious caramel by sacrificing their best trait (in his case beauty) and blamed Numbuh Five for allowing it to happen.
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.
Grandfather
GrandfatherFather and Monty Uno/Numbuh Zero'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.
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, 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.
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: Subverted. Monty Uno/Numbuh Zero seems to be this, as he does like him as his son and considers him the favorite...then tries to incinerate him when he turns on him without blinking an eye.
Actually he liked Zero more for the fact he was willing to stand up to him and give Grandfather something challenge.
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.
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.
Superpowered 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 eleborate fashion.
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.
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.
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.
I Want My Beloved to Be Happy: She and Numbuh One eventually break up when she realizes the world needs him more than she does, and that his first loyalty will always be to the Kids Next Door.
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.
Official Couple: Her and Numbuh One. They break up later, and actually she is the one who brought it up.
Palette Swap: She has the same character model as one of the Delightful Children From Down The Lane.
Tsundere: Type A and hard, sometimes dipping into yandere'ish tendencies in her more extreme moods.
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.
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).
