Chapter 1:
Numbuh 23:
Numbuh 23 was studying a pool. According to Sector V, a pool took them to the Negaverse. Many operatives thought they were crazy, but just for fun, she decided to take a look. It seemed like an ordinary pool. Maybe they were just crazy. She's missing Rainbow Monkeys Save Friendship for this? Numbuh 23 then walks, but she trips and falls in the pool.
...
Numbuh 23 gets out of the pool, but when she looks around, things seem different.
"What's Mr. Gyro's?"
"Hey look," says Knightbrace, who's for some reason, wearing a cape like Spankulot's and his mask has pointy ears, "it's Lettuh W!"
"Good work, Batfang," says Mr. Boss, "let's take her down!"
Then Sector V came, but there's something different about them. For starters, Numbuh 1 has hair, Numbuh 2 doesn't have his aviator hat, Numbuh 3's wearing a strait jacket, Numbuh 4 has an eye patch, and Numbuh 5 has a robot arm.
"Kids Upstairs, Battle Stations," says Numbuh 1. Wait, what?
The Kids Upstairs, as they seem to call themselves, then battled Mr. Boss, Knightbrave, Crazy Old Cat Lady, Toilenator, and a female version of Mr. Wink and Mr. Fibb. Something's not right here.
"We're going to have to regroup, Businessman!"
"You're right, Power Plunger. Adults, retreat!"
The Adults then left.
"That's right, keep runnin'," says Numbuh 4.
"Glad you guys came," says Numbuh 23, "but what's with the new look?"
"What do you mean, Lettuh W," asks Numbuh 2.
"Lettuh... I'm Numbuh 23!"
"That's a silly codename," says Numbuh 3.
"Wait... the pool! It brought me to another dimension!"
"Of course it did," says Numbuh 5, "this girl lost it."
"Right now, we should get back to my room," says Numbuh 1.
...
They were at the Kids Upstairs' HQ, which was Lettuh A's room. And boy, was it a room?
"Sure, is bigger than my room."
"What'cha expect," says Lettuh D, "Lettuh A is the Supreme Leader."
"Really? Do you guys have a Numbuh 362?"
"I'm pretty sure there are only 26 of us," says Lettuh E.
"Don't you refer yourself to the third person?"
"Why would I do a weird thing like that?"
Numbuh 23 then looks and notices Lettuh C was a little crazy.
"Is she okay," asks Numbuh 23.
"Only Color Chimps calm her down," says Lettuh D.
"Are they like Rainbow Monkeys?"
"You really are committed to this aren't you," asks Lettuh B.
"Lettuh B, we have work to do," says Lettuh A.
Lettuh B then kneels. "Yes Lettuh A."
The two then leave.
"That was weird. Mind if I take a walk outside?"
"We're not adults," says Lettuh E, "we don't care what you do."
"OOOkkkaaayyy."
...
Numbuh 23 then takes a walk. She notices some adults seem scared of her.
"My hair doesn't look that bad."
Then Businessman and his gang show up.
"Alright, tell us where Lettuh A's base is," says Businessman.
"Nice try, villains," says Numbuh 23, "but I'm not doing that!"
"What are you talking about," says Power Plunger, "you're the villains!"
"What?"
"We fight to teach kids valuable life lessons," says Businessman, "but you Kids Upstairs are the worst kind of bad influences."
"And we know you're working on a machine that will mind control kids into disrespecting their parents," says Batfang.
"That's silly. I mean, sure, Lettuh B did kneel before Lettuh A and their base did look like an evil lair, plus the fact that all the adults are afraid of me... I think we need to ask them some questions."
...
"The machine's almost ready," says Lettuh B.
"Excellent work," says Lettuh A, "maybe now Lizzie will go out with me."
"If we can brainwash her into not thinking you're a horrible heartless monster."
The five laugh.
Numbuh 23 comes in.
"Hey guys, there's some rumor that you are the villains."
Everyone looks at her in a confused way.
"Of course we are," says Lettuh D.
"What's with ya," says Lettuh E.
Then, there was a call.
"It's me, Lettuh W."
"Lettuh W," says Lettuh C, "then who's..."
The Five then look at Numbuh 23.
"You guys are gonna laugh."
The five were gonna attack, but then Businessman and his friends show up.
"Now we're talking," says Numbuh 23, "now, kick their butts!"
"We can't fight kids," says Businessman.
"What?"
"That's the one advantage they have," says Batfang, "we can't hurt them."
"Are you serious?"
"A pity," says Lettuh A.
"If you ain't Lettuh W, then who are you," asks Lettuh B.
"I bet you're my goody-goody sister using her bra to disguise herself," says Lettuh E, "she was always the favorite. It can be so..."
"Woah, easy Babe," says Lettuh D.
"Thanks Hon," says Lettuh E.
"Wait, your Abby and Wally are dating? There's something to disappoint the shippers," says Numbuh 23.
The Kids Upstairs then fire their weapons at the Adults, who tried to defend themselves without hurting the Kids Upstairs. Numbuh 23 then ran to the machine.
"Just as I thought," she says, "powered by hamster."
Lettuh A then grabs her by the throat.
"Nice try, Faker."
Businessman then grabs Lettuh A and throws him.
"You shouldn't pick on girls," says Businessman.
Numbuh 23 then destroys the machine, causing the house to explode.
...
"It's a miracle we survived that," says Power Plunger.
"It's a miracle we finally arrested Lettuh A," says Businessman, "and it's all thanks to you."
"My pleasure," says Numbuh 23, "there's just one more thing I gotta do before I go."
Numbuh 23 then shaves Lettuh A's head.
"You'll pay for that!"
Numbuh 23 then jumps in the pool as the Adults wave goodbye.
...
Numbuh 23 gets out of the pool and finds Sector V.
"Are you guys Kids Next Door?"
"No, we're Justice Friends," says Numbuh 4.
"I'm glad to be back."
"Numbuh 23, were you in the Negaverse," asks Numbuh 5.
"No, I was in a different world, but it did have an evil Kids Next Door, who wanted to brainwash all the kids, and I had to work with a heroic version of some of the Adults, who were like a public service announcement, Numbuh 1 had hair... and Numbuhs 4 and 5 were dating."
Everyone just stares.
"Yeah, she lost it," says Numbuh 4.
"Let's get her back to her treehouse," says Numbuh 1.
They will never know about Numbuh 23's adventure in Dimension 23.
