The Lunar Base of the Kids Next Door receives an encrypted message from Sector XW45-M. Numbuh 362 and 86 go to investigate but are interrupted by a nebulous storm. Chad, former Numbuh 274, manages to pass through and discovers an asteroid, which has an old KND ship. Inside, they find an agent still alive but in hibernation, possibly from the first generation of KND.

Really Overpowered foe. Need Incredible Numbuhs A New Villain arrives on the scene. Has sector V finally met their match? Please read and review!

Numbuh 451, otherwise known as Ava "Firecracker" Baros, was the Kids Next Door's premier explosive expert. If it existed, then Numbuh 451 knew not only how to blow it up, but often times, how to turn it into an explosive as well. But there is more to her than what the surfaces shows. She's known many of the KND's finest heroes and fallen operatives. This is her story.

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.

Between "Operation:C.A.R.A.M.E.L." and "Operation:M.O.O.N."After leaning that Sector "V" is taking some time off from fighting against those evil adults and teenagers, Kuki wishes that she never join the Kids-Next-Door after she made those minor accidents on her best friends/teammates and her Guardian Angel whom that she can take her to a world to see what will be like she didn't.

Living as a single mother can be a challenge especially with their child away and running business. Katherine wasnt going to let that stop her from getting know what going on with the children and adults fighting nonstop. She also met a man with his interesting children who seem to catch her interest.

A new girl claiming to be family shows up on the Uno's doorstep but not everything is as it seems as she trains to be an operative. Meanwhile, an adult with a connection to this child becomes involved in the DCFDTL's lives as trouble ensues.

Rachel is forced to have vacations as she hasn't stopped working in more than a year, the girl obviously doesn't listen to her friends and tries having her own kind of fun during her break *This was supposed to be the 50th story of the Romance In the KND series but I developed it so much in my head that I decided to make a complete story out of it

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

Meet the Favorite Fives! Steven, Linka, Luke, Crank, and Jennifer are five children who go on crazy adventures with each other. Whether it will be fighting off foes, completing tasks, or reclaiming valuable possessions, these kids go through some new and old territories by exploring lands that can be a challenge for them to get through. (Characters based on KND)

Based on Gettan49's Codename: Kids Next Dor Galactic Saga. A small difference forces Rachel T. McKenzie, Numbuh 362, to become a teen villain along with Sector V. How her time as the villain the Iron Maidan will change her, and her friends struggles? Who can say?

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?

Wally is the last member of Sector V who hasn't been decommissioned, with only months left until his own turn. As he struggles with loneliness and fading memories, he crosses paths with old friends who no longer remember him—and must decide how to navigate a world that's moved on without him. Now accepting OCs

Set after Operation Interviews. The KND has a new leader. But he quickly becomes a tyrant that Sector V and many others seek to overthrow. The main antagonist is an oc.

When a rogue operative threatens to reveal the GKND, Nigel is sent back down to stop them by any means necessary. But people have changed and the boy is tangled in a web of love and betrayal as he finds out just who he has been assigned to hunt down.

A look throughout the days of Rachel T. McKenzie/Numbuh 362 as Supreme Leader of KND and beyond.

Numbuh Vine, AKA Lizzie, receives her first Galactic mission to disguise herself as a regular human girl so she can test the loyalty of a certain member of the Kids Next Door. Trials and tribulations allow Lizzie to take extreme measures to complete her mission, which leads to her downfall and regret in what she has done when it is too late.

Wally can't remember the last time he spoke to Kuki Sanban but he somehow has her number saved in his phone.

Being sold to pay off a debt is not what I would like to happen to me. However, I don't have many options and I will do everything in my power to help these children, I will also take care of them until the debt is paid off. Until then, I'll just have to be the agent they want me to be. Kids Next Door, attack!

My genderbent version of season 1 of the show. I hope you enjoy! Apologies for the delay! I'll try to post new chapters as soon as I can!

The Sanbans are going to Tokyo, Japan for a family reunion. There, Kuki and Mushi will meet all of their relatives they've never met before and will have lots of fun!

In this story, Aaron's a superpowered teenager who's...not from around here. When trying to do what's right, his actions get the attention of the Kids Next Door. They might not trust him, but they'll have to if it means saving more than every kid's childhood from a bigger threat than Father. (Takes place after Operation: T.A.P.I.O.C.A.) Tell what you guys think! I hope you like it!

Their childhood dreams used to consist of fighting adult tyranny, but now they're full of college acceptance letters, state championships, good grades and getting laid. A teen fic starring Sector V and others.

A small stream of liquid trickled out from between his nephews fingers, dripping onto the carpet. It was crimson coloured liquid. Red...liquid... Father's yellow orb eyes widened in surprise as he realized what was happening to Numbah 1. "Are you-are you bleeding!" Father asked, anger replaced with concern as his nephews strange behaviour now made sense. (One Shot)

Father's workaholic tendencies come back to bite him when he grows too sick to stand. Even then, when the call for backup goes out, he crawls out of bed to try and destroy the K.N.D once and for all, with disastrous results. But when his illness subdues him, every operative is happy to lock him up and throw away the key. Except for a certain medic. Rated T for swearing
