How did the Delightful Children from Down the Lane become the way they are, and why did they make Nigel Uno bald? Just a two-shot to answer these questions and others...

Reliving your childhood years and into teens is one thing in your average isekai story, having it happen in the KND world is a different matter altogether. Very first Fanfic I made prior to my other fics. Posted on Spacebattles, now crossposting it over here.

Five years ago, Supreme Leader Numbuh 100 failed to uncover a conspiracy that resulted in the wrongful decommissionings of several operatives. Now, it's up to the teenagers to pick up where the KND left off, uncovering secrets that could destroy themselves and each other. But, maybe, they might just find out who the true enemy's been all along.

WARNING: SOME CONTENT IN THIS FIC MAY BE DISTRESSING TO SOME VIEWERS. IF YOU DON'T LIKE WHAT YOU ARE READING, PLEASE GO SOMEWHERE ELSE. THANK YOU! This is basically KND, but it's an AU where my character, Delilah exists, and how she came to live in Gallagher County. Co-written by giggly-gamer on Discord

When Sector V got reports of a strange, trench coat wearing teenager with a hook roaming around their neighborhood, they were all eager to get to the bottom of it, especially when said figure was spotted luring Numbuh 5 somewhere with a bag of her favorite candy. Cree, meanwhile, was not expecting her sisters' friends to crash their movie night over her prosthetic and coat.

One-shot. In the future, Father has taken over. Sector V now part of the TND join what's left of the KND to form the rebellion. Numbah 4 leads a mission to resupply their dwindling resources and gets captured. Can the rest of Sector V rescue him in time?

After barely surviving Bully Island, Wallabee Beetles learns there are consequences of his actions. However, Kuki Sanban is more than willing to teach him a thing or two about compassion and how an act of kindness can change a person's life.

"5 years." Kuki mumbled. "5 freaking years he goes missing and now he's back." (Sequel to Operation: K.N.D)

Los chicos del Barrio ya no son lo que eran en tiempos del grandioso Sector V, ahora hay problemas graves. Uno siguió con su vida como miembro de los Chicos del Barrio Galácticos y el resto creció, inevitablemente. Pero y si el líder supremo pidiera ayuda ¿Uno volvería para ayudarlos? ¿Sería capaz de ver a sus amigos convertidos en adolescentes? Houston, tenemos problemas

The Galactic Kids Next Door have returned and are ready to continue what they started ten years ago. Now, with the threat of their homes being destroyed, operatives from all corners of the universe find themselves forced to confront their demons in order to stop a cruel mockery of everything they stand for.

One year has passed since Father's defeat. The members of Sector V, without their memories, begin their sophomore year in highschool. However, the world isn't as peaceful as they think: the Galactic Kids Next Door have made Earth their next target while an old enemy lifts their head, seeking revenge. Only the KND and the TND stand a chance against them, but will they succeed?

The KND has a much darker history than anyone would think. Sector Z isn't the only team to go MIA. But maybe these other lost kids can help save the infamous sector.

WARNING - THIS STORY CONTAINS S%%CIDAL THEMES. IF THAT OFFENDS YOU, PLZ GO SOMEWHERE ELSE. A story inspired by a few of my favorite stories on this site!

Takes place around a year-ish after Nigel left Earth. The Galactic Kids Next Door have come to the Galaxy to destroy all Adult and Adolescent life in it. Can the Earthly Kids Next Door bring down the Intergalactic Organization? Rated T for Violence and such.

Fanny has tried desperately to hide her crush from Wally, and she's failed miserably. He's starting to catch on, and it's only gonna end one way. The only question she has is, will she like it? (YAY, a non One-shot Story) mostly focused on 4x86 and 1x362

I just made this while bored. I love this non canon ship a lot! So, I hope you enjoy this! Also, this story is supposed to be in the same universe as another fanfic that I'm currently also working on. I'll also most likely upload that, once I'm mostly done with it.

After being decommissioned and separated, Sector V and Numbuhs 60, 86, and 362 are back in Cleveland, but without the memories of each other or the KND. So now, it's up to Sector W to somehow restore their memories and get to the bottom of why they were decommissioned in the first place. A continuation of my first story. May change the title later.
