Operation HERO

KND/BNHA crossover, more of a crack fic than anything.

So I'm sure you can half tell where this is going. I don't own anything and I'm not even sure how people will like this, this has been sitting in my phone since late 2019 so around 3 years.

Chapter 1: Decomissioning

We open on what could only be described as pure mayhem as children dressed in armor made of scrap, toys, junk and even food containers rushed about in a panic. This was sector JP-M or mustafa japan. Six kids ran about panicked out of their minds as what could only be described as a large cat sized cockroach ran around the tree house command center trying to eat any and all snacks.

"It ate my cookies!" A blonde haired girl with sharp teeth a pillow tied with rope to her chest and left shoulder while a baseball mat covered her right shrieked as she threw a rock at the large bug.

"Calm down 72!" A short green haired boy shouted as he aimed a rifle made out of a soda can, a pack of gum, two sticks and a bottle of gumballs at the large bug. He pulled the trigger as a wild spray of pink gum pellets flew at the bug which proceeded to dodge everything. "83, where is the BUG SWAT? (Big Ugly Giant Super Weird Animal Trapper)"

"Working on it!" A pink haired girl shouted as she tried to fasten together a pile of junk using duck tape and chewing gum. "99, 97 behind you!"

"AHHHHHHHHH! EW EW EW EW!" 99, A small boy with black hair and rock like arms shrieked as he ran off with his hands in the air like a lunatic. 97, a bird headed kid with a living shadow shrieked in fright and fired a BAJOOKA ( Blasts Aloft Juicy Overfilled Orange Kartons amazingly) at the bug which just ate the carton fired at it.

"How did this thing even get in here?!" A girl with brown hair clad in armor made of pots, pans and hackysacks called as she fired a standard issue SCAMPP (Soup Can And Magnified Photon Phlaser) at the cockroach which proceeded to jump into an air vent. This was agent 51, she was just visiting for a routine training session due to lack of space in sector JP-E for the exercise when the bug appeared.

"I don't know 51." The green haired boy frowned as he turned to number 83. "Any clue?"

"For all I know its the delightful brats." The pink haired girl scoffed. "Yaoyoro-dork seems to think up the craziest things honestly. Remember the fart bomb snakes in a can?"

"Ew." The blonde girl gagged. "The whole tree house was stinky for a week and all the cookies smelt bad!"

"Is it gone?" The rock armed kid asked nervously.

"I hope so." Number 83 frowned. "It can stay away from my gadgets too! Hey 101, you got a plan?"

The green haired kid nodded as he pulled a pencil and notepad from his pocket. "If its only after the food I say we lay a trap, 97, 51 you help 83 with the trap, I'll go with 72 and 99 to flush it out."

"Oh man." 99 shuddered. "Why does it always have to be bugs 101?"

"Atleast we're not in sector A, imagine dealing with Count Spankula regularly." The green haired boy, 101, replied with a shudder of fear.

"Nuh uh!" 72 frowned. "Keep that creep way the heck away!"

"Isnt he your uncle though?" 83 asked.

"And he is creepy! Who goes around dressed in all black with a cape huh? Huh?!" 72 bit back.

The sound of something banging high above them in the tree house made them jump.

"MY COOKIE STASH!" 72 shrieked as she bolted up the stairs towards the source of the noise.

"Wait, don't go alone!" 101 called as he gave chase.

[Two years later]

Izuku Midoriya, agent 101 and head of sector JP-M, glumly stood before the assembled KND high command as he tried not to cry. He was the last of his team to get decommissioned. Toga and Tokoyami were first to go within mere days of one another, tokoyami through decomissioning and Toga was classed a runaway. Kirishima went two months ago and Mei had gone last week. The new team was due to fill his old sector tomorrow. To his left was the current head of decomissions a ginger girl known as Agent 82, he never knew her first name only that she was a few weeks younger than him and rude as anything towards everyone asides her direct superiours, often using her quirk to slap people upside the head when annoyed.

"We are here to mark the 13th birthday of one of our best, agent 101, notable for stopping the Delightful children several times over the years, giant monster dust bunnies and saving our own high commander number 09 from being frozen in peanut brittle. H-happy birthday izuku." The speaker, number 3190 choked back a sob as they too tried not to cry.

"I... I'll miss you all." Izuku sobbed as he blew out the makeshift candles on the ceremonial cake, it wasn't real, just a pillow covered in clay, paint and a permanent 13 shaped candle made of metal sticking out the top.

"Into the chamber 101." 82 scoffed as she japped a glue gun into his back. With a resigned shuffle izuku made his way into the chamber and was strapped down to one of the benches. "Smell you later teenager." She scoffed as she punched the On button. There was a bright flash of red as the door slammed down.

The crowd waited with baited breath for the screams to start. Nobody could stop a scream of pain whenever they got decommissioned, even those with pain nullification quirks. However this time, there was no screams, no yelping, heck not even a plea for help.

"Uh...86, I think something went wrong with the decomissioning thing." Izuku's voice was clearly heared over the silence making everyone gasp in shock. Never had this happened in the history of KND, even adults could be decommissioned.

"Teenager scum! What did you sneak in with you!?" 86 snarled as she hit the button to raise the door only to stop as she saw that everything was indeed working as it should, infact according to the dial the machine was set to 11 the highest it would go. "Uh... number 101 c-can't be decommissioned. Someone get 53 and 44!"

Two of the decomissioning squad members who were waiting by the doors rushed out to look for the two scientist kids, hopefully they knew what was going on.

"When they get back lock down the room." 09 called loudly from his seat which looked to be a floaty taped to a desk chair with a steering wheel for a head rest. "If teenagers are now immune to decomissioning we need a plan!"

"Uh... not to be rude but mum wants me back by 4 and its 3:45." Izuku called. "Its that or spankula." Many winced at that proclamation, none of them wanted to be subjected to the vampire's punishments and a majority of them wouldn't wish it on the adults or teens either, although maybe on the delightful children from down the lane.

[Three years later.]

Izuku hummed softly to himself as he got himself ready for the entrance exams for UA high. Much in his life had changed since his 13th birthday, his quirk made him immune to decomissioning and naturally the higher ups in the KND had freaked out and tried to keep him detained until he was let go with a tracking bracelet of all things stuck to his leg. It wasn't something many could track honestly, maybe the delightful dorks could but definitely not the adults or teenagers, thankfully he was out of it within a few weeks. Another side effect his quirk had that lead to a major freak out was the fact that he could recomission individuals by accident.

He had no clue how he did it only that he had accidentally recommissioned his own mum which was frankly terrifying when she freaked out over not being a kid anymore and started worrying if she was turning into a villain. Of corse him finding out his mum, the former number 2317 knew about the KND had sent him into fight or flight and he kicked reflexively hard enough to trip her over. That had sparked a full firefight in the living room when they both went for the KND weapon stashes and got each other stuck in nets and gum. It wasn't long after that 86 had shown up looking peeved about having to take a second shuttle that day to try and decomission his mother only to find out it hadn't worked.

A knock on the door gained his attention before his mum opened it. "Izuku, I made breakfast." Inko gave a soft smile. She had long forgiven him for the incident on his 13th birthday and honestly they were both glad that the geusts hadn't arrived at the time or things would of been a nightmare to explain.

"Thanks mum." Izuku smiled as finished tying his shoes and made his way to the dining table. Ever since his mum got her full memories she had taken to making a more child centric list of meals, brussle sprouts were banned in the house due to the knowledge of how dangerous they are and the fact they could at any moment turn into a litteral monster. Broccoli was restricted heavily for simular reasons and Rainbow Munchies was probably the only acceptable breakfast food asides pancakes and waffles.

"Don't forget your gadgets either and watch out for the delightful dorks okay?" Inko asked as she got herself her usual breakfast of mixed fruits and a bowl of mini waffles.

"Sure mum." Izuku nodded. Officially his quirk was his immunity to decomissioning and the ability to recomission others. On paper however it was the ability to use junk as effective weapons and tools. The pro hero Power Loader, the former number 17729, was stumped on how anything he had worked and in his hands was useless trash yet when Izuku used it they worked rather well, honestly it was probably worth the mess he had to clean just showing off a GUMZOOKA since he got to see Power loader throw a fit about how the gun is impossible and the damage it was capable of was also impossible seeming as how it barely bruised a person but punched clean through steel.

"Good luck, the new number 12 is having a meeting and I got 'invited' to explain to the new members of sector JP-N why attacking a recommissioned adult in her own house was a dumb idea." Inko sighed. She used to love the moon base as a kid now all she got was distrusting glares, whispers behind her back and a sore neck from having to duck through half of the doorways.

"If I'm back first I'll order ribs." Izuku smiled in sympathy. He was the second oldest "member" of the KND, he was even in charge of his own branch but the amount of regulations the leaders put on him was plain stupid, at one point a few months after number 09 was decomissioned number 99995 was in charge and she made him ask permission whenever he wanted to use anything KND, of corse she was kicked out and decommissioned within the week after nearly destroying the entire KND with her stupid demands, mostly for her favourite food and for the treehouses to all be designed in a certain way. That and she tried trading KND secrets to the delightful children for a tub of icecream with sprinkles.

"Hopefully I pass the test." He told himself as he rushed to finish his bowl of cereal, making a mental note to avoid the delightful dorks from when he was a kid.

He only ever bother learning Momo's name given she was the mastermind behind the group he encounted often, there was some blonde with a copy quirk was was arrogant as anything, a pink skinned girl who routinely would destroy any locks they had to enter the treehouse willy nilly until they changed the door mat to a trap, the dorks would always wipe their feet on it and get sent flying. There was a tall kid with half white and half red hair who was rude to even the other delightful children from what he saw and then there was a furry kid with glasses who despite being a raging buserker at times was the most well spoken of them.

Chapter end.

I can't really remember what else I had planned for this chapter honestly so I'll end it here.

Thoughts and comments?

Any idea for how this should go?

How should Izuku and the others react?
