Codename: Kids Next Door/YMMV

Codename: Kids Next Door is a show where Your Mileage May Vary. Kids may actually like this show, and even teens and adults. However, some may not like it based on its premise.

YMMV Tropes found in Codename Kids Next Door:
"Father: Ah, time flies when you're laughing with maniacal glee"
 * Big Lipped Alligator Moment: In Op W.H.I.T.E.H.O.U.S.E.,  It makes slightly more sense in context.
 * The apparent assumption was
 * Complete Monster: Minor recurring villain Chester has no qualms about using children in his moneymaking schemes, but what truly qualifies him for this title is when he's perfectly willing to sell live "Kid's Meals" to sharks in "Op: FAST-FOOD".
 * Grandfather. He's probably one of the most evil villains in the entire show. He turned the entire world into 'Senior Citizombies' just because kids annoy him. He's also the reason Father is the way he is. Fridge Horror makes him seem even worse.  Evil indeed.
 * Nurse Claiborne. This woman runs around, giving kids a horrible and debilitating case of pink eye for the sole perpose of making apple crumbles out of it for money. While that's pretty bad, she really places herself on this list with her actions in her second appearence. She runs a "retirement home" for Rainbow Monkey dolls where she takes the Rainbow Monkeys and grinds them up into breakfast cereal. While in-universe this is horrifying, her Moral Event Horizon is trying to do the same thing to Numbuh 3 with a smile on her face. Some villains do some messed up stuff, but she's one of the few who actually tried to brutally murder one in cold blood. She's also one of the few villains who is played completely straight and her actions treated as criminally insane in-universe.
 * Crowning Moment of Awesome: Has its own page
 * Crowning Moment of Funny: The end of Operation: A.R.C.H.I.V.E.


 * Numbah 1's reaction to finding out that the "code" on the Rainbow Monkey Island tablet in Operation: F.E.R.A.L was . He didn't take it well.
 * Crowning Moment of Heartwarming: A few here and there but the movie especially has several. Most notable
 * Real Life incorporated into the show: a Make-A-Wish Foundation patient named Jacob "wished" to be in an episode of KND. Jacob appeared as a scientist named Numbah 275, albeit only a few times and with no spoken lines, in the second half of Operation: F.E.R.A.L.
 * Crowning Music of Awesome: The rock opera episode, complete with a score by GWAR, who re-performed the song themselves after being unable to find stock copies.
 * Designated Hero: Sometimes one can't help but tilt their heads at the K.N.D's actions, like in the episode where the agents fight against a rabid, Batman-esque dentist, whose heinous crime is to improve the kids horrendous dental health. On another episode, the kids hijack a delivery truck to destroy Type-P torture devices, aka pianos. So, what about the kids who like playing? They never stop to think about an hypothetical little timmy whose only dream in life is to become a famous musician?
 * In the case of Nightbrace, he turned out to actually be quite heinous because
 * As for the piano incident, the focus of the episode was actually about the KND being injured and replaced by hamsters. The piano incident was the pretext for their injuries to occur, so we weren't given the full context since it was a Cold Open. Given how KND villains tend to behave, in context the pianos were probably part of some villain's scheme to enslave children with piano lessons, or something along those lines.
 * Designated Villain: Done deliberately with Professor XXXL, who in all his appearances is just trying to create the perfect snowcone, but the KND always ruin his plans thinking he is doing something evil.
 * Ear Worm (Rainbow Monkeys, Rainbow Monkeys...)
 * And the opening theme. (Dun nun nun NUN nun . . .)
 * Robin Food's theme tune.
 * HIP HOP. HIP HOP. GONNA DROP DA BUNNY!
 * Ensemble Darkhorse: Rachel, aka Numbuh 362.
 *   You won't believe the huge fanbase they have after only, what? Five minutes of sceentime?!?!
 * Fan Preferred Couple: Numbuh One/Numbuh Five
 * Numbuh One/Numbuh 362
 * Numbuh Two/Numbuh 86
 * Numbuh Three/Four were this in the first season thanks to fan reaction to "Operation: O.F.F.I.C.E." The escalating Ship Tease in the subsequent seasons upgraded them into Official Couple status.
 * Numbuh 65.3/Lizzie: They're both glasses-wearing geeks. In "Operation: L.E.A.D.E.R.", Lizzie pretends to flirt with him and says she likes his pocket protector, making 65.3 blush. In ". In "Operation: G.I.R.L.F.R.I.E.N.D.", 65.3 tells Nigel to say 'hi' to Lizzie for him.
 * Foe Yay: Numbuh 5 and Henirich Von Marzipan.
 * Funny Aneurysm Moment: A day-long KND marathon which ends with kid dominance over Cartoon Network being proclaimed is immediately followed by -- yes, Adult Swim.
 * Operation: G.R.O.W.N.-U.P. has Father and a grown-up Numbuh One facing off, and, after Father comments on how useless the DCFDTL are, Numbuh One responds with "that must run in the family". And then, in the same scene, Numbuh One says that "his Grandma can throw better than [Father]."
 * In the Kenny and the Chimp pilot, Kenny got...Swine Flu.
 * "Operation F.U.T.U.R.E" is a Terminator parody, where girly girls take over the world from an all girls school and the last rowdy boys are fighting a losing battle against them. Many academic studies show that in Real Life the girls are increasingly taking over, due to being generally better students and that todays rowdy boys are going to be tomorrows losers.
 * Tiger Moms - the battle against adult tyranny is as important as ever!
 * Growing the Beard: The Season 1 Finale established continuity for the series, as well as the introduction of Father and the fact that the KND is not just the five featured on the show, but rather many different sectors.
 * Harsher in Hindsight: In Kenny and the Chimp, one of the joke diseases that Kenny get is Swine Flu. And then in 2009...
 * Jerkass Woobie: Father, after Operation Z.E.R.O. (and minor moments in I.T. and C.A.K.E.D.-F.I.V.E.)
 * Memetic Badass: Just watch Op. K.N.O.T. and try to say Moosk doesn't have the makings of this.
 * Harsher in Hindsight: In Kenny and the Chimp, one of the joke diseases that Kenny get is Swine Flu. And then in 2009...
 * Jerkass Woobie: Father, after Operation Z.E.R.O. (and minor moments in I.T. and C.A.K.E.D.-F.I.V.E.)
 * Memetic Badass: Just watch Op. K.N.O.T. and try to say Moosk doesn't have the makings of this.


 * Moral Event Horizon: Chester trying to feed live children to sharks.
 * Nurse Claiborne trying to outright murder Numbuh 3 and turn her into breakfast cereal.
 * Nausea Fuel: One episode where "chicken pox" takes the form of literal squirming chicken heads sticking out of one's skin.
 * A villain named the Common Cold attacks by siphoning mucous out of his nose. Especially lovely when he starts to ready a really big attack.
 * In Op PINKEYE, being hit with a water balloon filled with pinkeye mucus would cause crusty red stuff to grow all over you. The episode's villain turns out to be using this crusty stuff as the crumbs in crumb cake.
 * Oh my god I need to throw up.
 * It gets even worse at the end of the episode: "So if the pinkeye was the crust, then what was the filling?"
 * Even worse? In a two later episodes, Numbuh Two still eats the stuff and he comments about it as well!
 * Is no one going to mention Op VIRUS, where there is a close up of Cree's gigantic and disgusting pimple?
 * A few of The Movie's senior citizombies had sagging Gag Boobs.
 * Nightmare Fuel: Apparent in a few episodes.
 * I can not be the only one who was scared to death of the Delightful Children.
 * It's even more terrifying when you know who they REALLY are, and what happened to them.  was captured by Father himself, and put them through such rigorous torture (or as he puts it, Delightfulization) to the point that's it's quite literally IMPOSSIBLE to turn them back (any attempts are just temporary). To think that such honorable members of the KND have been turned into such monsters is not only scary, but you have to think of what kind of treatment father put a couple of TEN YEAR OLDS, not to mention that the torture was so intense that they work as one being.
 * Heinrich, Numbuh Five's nemesis, trying to dunk a live rabbit in molten chocolate. Terrifying.
 * Even worse when he soon after.
 * It Gets Worse! Don't forget that
 * It Gets Worse! Even worse than before!
 * Ever worse than that!
 * The Crazy Old Cat Lady in her first appearance.
 * Grandfather, Father was originally scary, Grandfather takes it to another level. Sure, he's got some humor, but overall, he's just scary.
 * The Pirates of the Caribbean parody episode. Somehow, turning into licorice skeletons seems scarier than turning into regular ol' skeletons. And that's not mentioning what happens to them when the sun comes up...
 * There is one episode that was so deeply unsettling, I couldn't even watch it without becoming scared during my childhood. The plot involves Nigel reading a report about the creation of adults or something like that, and it seems to appear on a happy term of ending. Until it wasn't. There were scenes shifting to live action showing brains being microwaved and blended, then the scenes started to become more fast paced and Nigel was starting to speak in what appears to be complete gibberish.
 * Am I the only one who was terrified of the part of W.H.I.T.E.H.O.U.S.E where Nigel hulks out?
 * Periphery Demographic
 * Squick: Anything that involves Nurse Claiborne.
 * Her apple crumble is topped with eye shit!
 * That ran into serious Nightmare Fuel for this troper...
 * That's nothing compared to what the apple crumble filling is implied to be. How can Numbuh Two stand to eat the stuff, knowing just what it's made out of?
 * Rainbow Monkey Cereal is made with
 * Zombiefied Numbuh Three and Four kissing each other. (Shudders)
 * Could've looked way cuter if they were normal, but as old zombies...(pukes)
 * Toenails collection. I mean seriously, what?
 * Even worse was the subtle revelation that the Delightful Children use the bathroom together! Seriously, what the FUCK?!?
 * Tastes Like Diabetes: It's not hard to see why Numbuh 4's not all that fond of Rainbow Monkeys.
 * Tear Jerker: Has it's own page.
 * They Wasted a Perfectly Good Plot: The KND "Splinter Cell" arc foreshadowed an internal civil war in the KND between the extremist Splinter Cell that believes all adults must be destroyed vs. the more moderate faction that believes only the evil adults should be stopped. It is also revealed that the Splinter Cell had been kidnapping KND scientists for unknown reasons. However, near the end of the series, it turns out that the Splinter Cell is just an front for the KND scientists, who fake their kidnappings so they have more free time to watch their favorite science fiction shows as well as manage "the Galactic Kids Next Door", the workings of which were left very vague in the end.
 * Toy Ship: Several.
 * In the main team alone; 3+4 didn't so much have subtext as it was just plain text from the start, 2+5 was a slightly more debatable case, and 1+5 had some good chemistry. But let's not get into the web that the fans (and creators) have spun.
 * Ugly Cute: Ramon 4 from Op SATURN.
 * Unfortunate Implications: In Op CARAMEL, we find out that bitter villain Heinrich Von Marzipan is really a girl magically turned into an evil boy. After he's returned to being Henrietta Non Marzipan, she instantly stops being a villain. So apparantley the cure to all male evilness is to become female.
 * That isn't the point to the episode; the reason Henrietta became Heinrich is because she ate caramels created from the most vital part of her personality (feminine beauty). As a girl, she sold out for candy. The rest of Sector V fall under the curse during Op CARAMEL, making Nigel indecisive, Hoagie primal, Kuki gothic, Wally cowardly, and Abby nerdy. This Troper thought the aesop was "Don't change who you are for something you think you want."
 * Plus, as one two-parter demonstrates, turning guys into girls could make them evil. As in Straw Feminist evil.
 * In Op AFLOAT, Numbah Five hands Stickybeard a purple (grape?) lollipop.
 * Villain Decay: Father started out as... well, pretty much Satan. Scary, always cloaked in darkness, and biblical in his wrath- and of course, his voice is Maurice LaMarche at his scenery-chewing best. Contrast this with the middle-aged dork he became later on.
