History YMMV / CodenameKidsNextDoor

* ToyShip (''Several''.)

* GannonBanned: It's deliberarely spelled as "[[XtremelyKoolLetterz Numbuh]]", not "Number".

* MissedMomentOfAwesome: Are you kidding me? How completely bad ass would it have been to see FATHER fight GRANDFATHER, both at full strength?
** From the very same episode: "Looks like I finally get to try out my new move, guaranteed to take out four enemies in one shot." Cue the villains calling a retreat.

** A few of TheMovie's senior citizombies had ''sagging'' ''GagBoobs.'' [[spoiler: This included the citizombified versions of [[NoJustNo Numbuh Three and Five.]]]]

**** ItGetsWorse! Even worse than before![[spoiler:Heinrich fell into the chocolate and became an eldritch abomination!]]
**** Ever worse than that! [[spoiler:Heinrich is really a pretty little girl!]]

** 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). 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 [[AnAesop aesop]] was "Don't change who you are for something you think you want."
** Eh, this technically makes her a {{transsexual}} in a male body. Perhaps the malice could be fueled by her gender dysphoria, and desire to turn back to normal?
* VillainDecay (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 wimp of Op ZERO.)

** However, unlike [[FridayTheThirteenth other]] [[DannyPhantom examples]] of this trope, Father managed to recover by the [[GrandFinale series finale]]. [[TookALevelInBadAss And boy, did he]].
** To be fair, that particular example is when he's up against Grandfather, who is basically Father'''[[VillainSue + ]]'''.

* CompleteMonster: Minor RecurringVillain 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 [[ToServeMan "Kid's Meals"]] to sharks in "Op: [=FAST-FOOD=]" .

** Nurse Claiborne. This woman runs around, giving kids a horrible and debilitating case of pink eye for the sole perpose of making ''[[{{Squick}} 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 ceral. While in-universe that's terrible, her MoralEventHorizon 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 ''kill'' one in cold blood. She's also one of the few villains who is [[KnightOfCerebus played completely straight]] and her actions treated as criminally insane in-universe.

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

** More and more studies show that todays rowdy boys are going to be tomorrows losers, because the girls overtake them in the educational race - Operation F.U.T.U.R.E., anyone??

** However, unlike [[FridayTheThirteenth other]] [[DannyPhantom example]] of this trope, Father managed to recover by the [[GrandFinale series finale]]. [[TookALevelInBadAss And boy, did he]].

** [[spoiler: The Ending of Operation: INTERVIEWS, when Numbuh 1 is forced to leave Earth. Thankfully, [[CrowningMomentOfHeartwarming his parents see him off with a good-bye.]] This troper heard some FridgeLogic on whether or not his parents should have let him go. Well, FridgeBrilliance occurs when you realize no ''good'' parent wants their children to leave (most of the time they leave to College), and if they let them go, they risk that they might not be able to see them again. (Not that it's always the case, but still.) That's exactly the same case here, making this scene even more effective.]]
