Reader has a Numemon (they/it), this has led to issues making friends due to superstition and rumors, after a prank however Numemon decides to deal with some punks
When your digiegg had hatched and the weird green and purple blog with eye stalks stared back at you, your chest did fall, a Numemon??? What happened how did you manage to hatch such a digimon, everyone else was getting Biyomon, or or Patamon or Shoutmon or, your new partner just stared at you in quiet adoration even as the resentment grew in your gut.
From that point on you were a social outcast, people didn't want to be friends with the kid who had a pokemon who threw shit at people, no matter how hard you'd tried locking Numemon in your room, in the shed, in a crate! They always managed to get out and make their way back to you and people left you repulsed.
They'd start to joke about smelling something awful, sniffing in your direction and going "pee-ew", like they were the most funny person in the room, you withdrew sitting at the back of class with your shame, you were only a child entertaining yourself by poking the stalk eyes with the eraser of your pencil to watch them close retract and then pop back up.
It took you a couple months before you realised, it's just a slug, Numemon is a just a mollusk digimon, watching it's stalk eyes that you used to hate, head tilting as you catched them quietly munch away on a lettuce leaf you'd taken out your sandwich, reminded of when your grandma once showed you her greenhouse and the slugs that were gently misted with water and ate the leaves.
That weekend you took Numemon into the back yard with you as you did your chores, weeding the plants to earn a bit of pocket money and handing them the weeds, watching them happily gobble them down looking like you'd just given them the most delicious chocolate cake in all of the world. When it was safe to, you readied the hose, spraying down the plants, and, you turned the hose to mist, holding it over the Numemon.
The response was instantaneous, despite being a blob they tilted their head up, eyes closing and they looked, so peaceful.
Your outlook on your Numemon changed that day, it wasn't some vile disgusting sewer mold, they were just a slug, and you came to find, they were a good slug. They weren't as gross as everyone thought, they weren't sticky and slimy like the other students claimed, nor did they actually smell. They were a good slug.
After that point you didn't care so much what other people thought, and after more research you found out it's a champion level digimon? Making it higher level than any other in your class?? Now that baffled you. Not that you and Numemon battled, you weren't the kind.
All the stupid childish things started to roll of you like water on a ducks back, you liked your digimon screw anybody else who didn't!
You were in high-school and it was coming up to Halloween when it happened, you'd been so excited for a haunted house that featured animatronics and actors, it was a whole thing. The toilet water was cold as it was plunged onto you from above by some boys howling "Trick or shit!" wet soggy toilet paper clinging to your body, and you stunk. You stunk so bad.
The office let you go home early, maybe so you didn't smell out the office sobbing and shaking, you don't even know if the boys got reprimanded you doubt it past murmurs of "well they kinda brought it on themselves" from callous classmates.
You'd gone home and showered instantly spending probably longer than needed trying to get the stench off of you, your clothes in the wash desperate to get out the filth. You didn't have any energy as you collapsed into the bed, and sobbed. Numemon stood besides your bed, sensing your hurt and aching, they knew what those other humans did was wrong, in human laws that was probably assault, and even the digimon knew they'd unapologetically attacked their human.
Numemon was always good at escaping, ever since they first hatched, and with you collapsed exhausted in bed it wasn't so hard to slip out unnoticed. Numemon surprisingly have a keen sense of smell, and it listened. Those boys were going to the same haunted house you'd gushed about going to, now too broken to bother.
In the dark it slipped past humans, and into the back, stalk eyes gazing up at the animatronics, a faint snicker at the WaruMonzaemon animatronic, and other miscellaneous things, but it knew exactly which one it wanted, boneless body slipping inside of the metal body with ease, figuring out how it moved which gears did what. Sure it got pinched and squished but they didn't feel it, mastering the manipulation of the suit and then dormant waiting.
It didn't care when it's body was compressed and squeezed as the animatronic worked off of coding on how it should move for the folks, eyes watching each passerby their shocks and surprise.
When they saw those two boys, they could've leapt out and started biting them itself, but it waited, letting the routine run, as junk from the digital world materialised at the exit and entrance, effectively locking them in and others out. The boys pushed and shoved each other snickering hardly afraid.
Numemon had never spoken before, but it's voice eerily croaked out both the boys names once the routine was over, causing them both to stop, lazily controlling the animatronic to blink, the show began.
"I see you both there, you were not afraid?" they seemed in awe, wondering if this was part of the show.
"Dude they must've put the guests names into the data banks," shoving their companion.
"You're both so clever," the 'animatronic' praised, "too clever for me, do you want a photo to show you're both brave?" Numemon, was a virus, and it knew how to talk to both of their ego, the clear leader of them both smirked moving to duck under the safety rail.
"Damn right I do" "Wait dude, the sign says it's not safe" "well duh? That's for the effect!" "If you say so," the second boy came closer.
Numemons jaw was tense, trying not to audibly grind his teeth as he made the animatronic move for photos. "Now, who wants a hug?"
The leader shoved his friend close, so close he bumped into the robot, "Go on hug your friend, I'll get photos!"
"W-wait, I don't wanna" the animatronics arms came around him regardless.
"Hug time~!" the tone was joyous and the boy made an uncomfortable sound but posed for the photo, before the panic set in.
"that's enough, that's enough you can let go, l-lets go! Ah! AGH LET GO IT HURTS" He started to scream as the animatronic arms kept compressing from the Numemon control, spine slowly breaking, ribs cracking and puncturing the organs they were meant to protect, the look on the other boys face when he realised it wasn't a joke and his friend was indeed being crushed before his very arms.
And he ran.
Much like Numemon expected him to, desperately crashing into the junk and trying to rip it away cutting open his palms and slicing up his hands on the assortment of junk as his friends screaming went quiet, only the squelching of his limp frail body before the sickening thud as it was dropped.
The animatronic ripped from its stand, it stepped and stepped again, and the lead bit hands all cut up started to cry and scream out for help that couldn't get through.
"IT'S GOING TO KILL ME, IT'S GOING TO KILL ME"
The WaruMonzaemon animatronic stopped right behind him, and he made a pitiful whimper when he felt it breathe on him, b-breathe? Trembling he turned to face the now bloody animatronic in mounting horror.
"Trick or Shit," the boys mouth was dry and he barely had time to widen his eyes in horror before the claws of the animatronics hand were buried into the soft flesh of his gut. It seemed to debate for a second before the Numemons soft body slide out of the animatronic, leaving the boy pierced on claws held slightly off the ground unable to pull himself free, and help wouldn't be able to get to him fast enough.
"Nye-nye-nye," the vocal stim of the Numemon like a laugh before it slipped away through a gap only accessible by it's form, past the staff who were desperate and frantic and into the night it disappeared.
The horrors of the haunted house was all over the media the next day, nobody knew what happened, the camera was busted and how did the animatronic securely held in place and powered by mains rip itself free??
You didn't see the news however, or hear about the horrors until you returned to school the following Monday, you'd taken the long weekend since coming back on Thursday afternoon, not feeling well enough to dare show face on Friday faking a cold. Numemon had attempted to make you breakfast, lettuce leaves on a plate, and your cereal in a glass cup with milk, it was endearing and sweet and expectedly weird as it used it's stalk eyes to place the good tray in your lap.
You softly pet the top of your partner digimons head, and it made a soft trill. When you heard the news, it never once crossed your mind what they were truly capable of, after all, they're just a slug.
