History WMG / CodenameKidsNextDoor

[[WMG: Numbuh Aleph Zero could alternatively be an AbsoluteXenophobe of the purest kind.]]
It could tie in to the above theory that the GKND somehow [[ILied lied]] about the "adulthood disease" and really views all life, [[HumansAreBastards human]] and [[AliensAreBastards otherwise]] as violent and primitive. The fact they've got a WeaponOfMassDestruction mounted to their flasghip/base is a sign [[OmnicidalManiac they're definitely not stopping at killing adults]].

[[WMG: Numbuh Aleph 0 [[EvenEvilHasLovedOnes has operatives they genuinely trust and care for]].]]
Sure Aleph 0 may be [[TheSociopath psycho-sociopathic]] and [[StrawNihilist borderline nihilistic]] but there's a few operatives whom they have enough metaphorical heart to give a damn about; particularly their [[TheDragon second-in-command]] and first partner [[AccuserOfTheBrethren Numbuh Nominal]]. While Nominal has differing beliefs they have matching interests and work on solutions to their problems.

One or more of the GKND operatives could already be immortal or have the "cure" through experiments. While it could be beneficial people like Father can use it to their advantage against the Earth KND because if they test it on Numbuh 1 and nobody else [[AndIMustScream he'll spend eternity being alone]] [[GoMadFromTheIsolation and further going insane]] while his friends and family grow up and without their best operatives the KND will fall.

If the tapioca factories spewing smog and him [[RapidAging ageifying]] non-human species like the hamsters mean anything.

Enter Numbuh Aleph 0 (alternatively known as Numbuh Omega), an [[PhysicalGod incredibly powerful]] PsychopathicManchild who's [[ReallySevenHundredYearsOld over 1000 years old but still a preadolescent in their species' lifespan]]. They have [[KnightTemplar more nefarious views]] on fighting adult tyranny, believing the organization to be CoolButInefficient and taking it to the [[LogicalExtreme next level]] by [[FinalSolution wiping teens and adults off the face of the universe]].

It only makes sense ''GKND'' continues along that route - The second is Father's presidency while the first is Numbuh 1 having a MyGodWhatHaveIDone moment, the kids, teenagers and adults being pinned down even with the good GKND operatives and Sector Z fighting alongside them and Numbuh Aleph 0's weapon charging up to destroy Earth. Of course this is where [[SpannerInTheWorks Toiletnator]] has his BigDamnHeroes moment and disables the weapon.

... To discover or develop a form of {{immortality}} that makes children never have to grow into adults. After all, even if they wiped out every adult in the universe those children whose rights they're so adamant about defending are going to grow into adults themselves someday. Their plan is to exterminate all teenagers and adults, then spread the "miracle cure" to all children of the universe. Unfortunately, people treated with the cure can still die from outside forces so it really doesn't make them all that immortal.

Much like what happened in WesternAnimation/ThePowerpuffGirls1998, Father uses a TimeMachine to [[MakeWrongWhatOnceWentRight kill his brother as a child and ensure the Earth KND's Seventh Age never begins]]. This has setbacks for both him and the KND operatives trying to stop him as [[TheDarkLord Grandfather]] was active around that time and Young!Numbuh 0 hasn't gained enough courage to rebel. The duel between the KND and Father will inspire him to rise against adult tyranny, setting up a StableTimeLoop and SelfFulfillingProphecy, both of which would'nt have happened if [[NiceJobFixingItVillain Father never bothered intervening to begin with]].

Nigel doesn't just leave for decades when the GKND obviously has hyperdrive engines plus the Post-Splinter Cell GKND and EKND are gonna merge operations at some point. Sector V probably used makeup, hair dye, prosthetics, etc. as part of a BatmanGambit against Father. It would only be a five-year Time Skip.

Only the protagonists will be REAL adults and have kids to [[PassingTheTorch receive the torch]]. Plus the whole thing could be a SelfFulfillingProphecy to what they say in Operation I.N.T.E.R.V.I.E.W.S. with Wally graduating from Harvard and Kuki being the Rainbow Monkey Corp. CEO. The ending could also take place on Nigel's birthday with the gang getting back together much like ''WesternAnimation/{{Amphibia}}'' and the whole ''KND'' series could be archived transmissions viewed by their children and such similar to ''WesternAnimation/RegularShow''.

Probably because he's realizing he needs her as much as the rest of his teammates, plus to fill in the gap as a second-in-command while Abby is the Supreme Leader, though Numbuh 5 will still hang out with him in the treehouse and go out on missions with him because TrueCompanions don't leave each other behind.

It pretty much serves as BookEnds to the Earth KND's history as the close younger relative of a tyrannical overlord takes them down and saves everyone.

Much like WesternAnimation/ThePowerpuffGirls1998, Father and Numbuh AZ will use a time machine to kill Numbuh 0 as a child to ensure he doesn't start the Seventh Age of the KND. This has setbacks for both them and the KND operatives trying to stop them as Grandfather was active around that time and Young!Numbuh 0 hasn't gained enough courage to rebel against him. The duel between the KND and the villains will inspire him to rise against adult tyranny, setting up a StableTimeLoop and SelfFulfillingProphecy, both of which would've never happened if [[NiceJobFixingItVillain Father and Aleph 0 never bothered intervening to begin with]].

It only makes sense ''GKND'' continues along that route - The second is Father's presidency while the first is Numbuh 1 having a MyGodWhatHaveIDone moment, the kids, teenagers and adults being pinned down even with the good GKND operatives and Sector Z fighting alongside them and Numbuh Aleph 0's weapon charging up to destroy Earth. Of course this is where Toiletnator has his BigDamnHeroes moment and disables the weapon.

And with the upgraded Moonbase introduced in Operation Z.E.R.O. there's going to be some slight changes applied to it.

Whether they be created by Numbuh Aleph Zero or otherwise.

Not only is he (supposedly) immune to the side effects of adulthood but he's a vital part of their plan and if he's decommissioned he wouldn't know about the GKND.

[[WMG: ''GKND'' will feature more moments in Cleveland.]]

* Perhaps Lizzie, Numbuh 74.239 and Numbuh Infinity are adults disguised as kids. It would explain their deeper voices in their alien forms from the teaser.

* Or the Darkness could be a reincarnation of them and the final form could be a different type of EldritchAbomination.

Probably to renew series tradition of surprising people with putting deleted scenes on home media. Not a lot of recent home media releases do that, so this would be a return to form.

[[WMG: Operation T.R.E.E.S. will be reworked and released.]]

* I think this will be jossed. The animatic was shown to be close to the show's art style even though it hasn't gotten to the final stage.
** Further jossed by the fact that a company named Rat Animation released an animated version of the pilot which closely follows the original show's animation style on their channel and they wished to animate the show if it gets greenlit. Unfortunately their channel has been deleted since so it's unlikely they're still active even though the video's been reuploaded.

[[NoJustNo Nope.]] [[WesternAnimation/ThePowerpuffGirls2016 The last time]] [[WesternAnimation/TeenTitansGo they did something]] [[WesternAnimation/Ben102016 like that]] [[TheyChangedItNowItSucks it sucked]]. The design needs to be as close to the original as possible.
* And it's jossed. The teasers have designs accurate to the original show.

[[WMG: One of the goals of the GKND, possibly even their ultimate goal, is...]]
... To discover or develop a form of {{immortality}} that makes children never have to grow into adults. After all, even if they wiped out every adult in the universe, those children whose rights they're so adamant about "defending" are going to grow into adults themselves someday. Their plan is to exterminate all teenagers and adults, then spread the "miracle cure" to all children of the universe. Unfortunately, people treated with the cure can still die from outside forces so it really doesn't make them all that immortal.

[[WMG: Numbuh 1 will [[SixthRanger allow Numbuh 362 to join Sector V.]]

While a good majority of the characters have been helping out in every major battle of the series, Nigel will have to enlist the help of the [[UpToEleven entire universe]] in the final battle against the Splinter Cell. Even ''Grim'' will join the action.

It turns out his actions of murdering adults since he was a kid are recorded. With this Johan plans to use the war to cause TheEndOfTheWorldAsWeKnowIt. If it keeps happening he'll succeed.

Unlikely. Even if on streaming shows like '' Fionna and Cake'' having up to 10 episodes per season and passing the one-season mark goes to show ''GKND'' will end up warranting multiple seasons as well.

Unlike Chad who was a GloryHound and actually an AntiHero with responsibilities Cree really had no regards and there were signs of her already becoming a traitor while in the KND. One guess is that she felt [[ParentalAbandonment abandoned]] after Numbuh 5's birth and got tired of being sidelined in favor of her sister so she dropped the "kid gloves" and went primal even before turning 13. That might've somewhat slightly changed around Operation S.P.A.C.E. after Numbuh 3's sister [[CuteAndPsycho Mushi]] convinced her to stop fighting her own responsibilities (being a sister) and instead realize she still has family who cares for her as much as they did with Numbuh 5.

In a case of SurprisinglyRealisticOutcome not all of them follow Lizzie's example, instead choosing PatrioticFervor and creating TheRemnant. This forces the [[Badass BadassPacifist]], [[TechnicalPacifist Technical]] and MartialPacifist KND operatives to go up against and neutralize them.

And the collaborations against [[EvilOverlord Numbuh Aleph Zero]] and later [[TheCaligula President Father]] will get them to merge operations.

[[WMG: Numbuh Nominal is the child of another animation villain like [[WesternAnimation/{{Villainous}} Black Hat]] or [[Franchise/ThePowerpuffGirls HIM]].]]

[[WMG: Numbuh 1 will share his sector's treehouse with Sector Z.]]

[[WMG: Numbuh 1 will allow Numbuh 362 to join Sector V.]]
