Doom: Izuku's guide to not act like a blood thirsty soldier.

Summary:

He misses his own dimension, he misses acting like himself, misses wearing a mask everyday because of air pollution, he misses fighting for his life everyday, he misses the weight of the gun in his hand and misses having to worry about starvation.

He might be as crazy as Samuel initially thought, maybe more.

No wonder why the bastard tried to lock him up forever...

Chapter 1: Samual come pick me up i'm scared, please put me back in eternal sleep

Chapter Text

Izuku thought that life would be easier on this new dimension, no demons, no abusive mother, no worries about not having something to eat everyday.

But the truth is.... He misses his own dimension, he misses acting like himself, misses wearing a mask everyday because of air pollution, he misses fighting for his life everyday, he misses the weight of the gun in his hand and misses having to worry about starvation.

He might be as crazy as Samuel initially thought, maybe more.

No wonder why the bastard tried to lock him up forever.....

Sometimes he still thinks on what would happen if he stayed in his dimension, he knew that it was basically destroyed by now without him there to protect it, he new it and he hated it, no more demons to hunt, no more human assholes to betray, nothing.

And now everything he did was sit quietly in a chair of a middle school classroom remembering his golden years, he knows he's being dramatic but come on, he was fourteen, in his dimension people died before they could even step a foot in college, in fact, college didn't even exist in his dimension, he should be out there enjoying life instead of having to sit here and listen to the things he already knows being repeated not by a general with years of experience in a battlefield, but by a quirkist teacher who had a personal vendetta against him for the simple reason he didn't have a "quirk", like that mattered, he killed millions with a dagger and a cereal bar, he didn't need a cheat code to do it, no one in his world had powers and they turned out fine, dead, but fine.

And the worst thing about this new dimension was the guy who sat at the table right beside him, Katsuki Bakugou, his "childhood best friend" that the other him had, he hated him, hated him with all his rotting heart.

Logicaly he knew Bakugou was nothing else than the victim of a system who made everything about how powerfull you are, not by physical strenght, but by quirk, and he shouldn't be hating on a child that never knew any better, in fact, he should be glad children weren't given guns as soon as they knew how to walk or being underdeveloped because reading writting and having social skills wasn't entirely nescessary in a battlefield, but when you're forced to call someone as annoying as Bakugou "Kachan" as an affectionate nickname you start to feel hate boiling under your skin.

And he hated it, hated it with a passion that could only be rivaled by Eros, and Izuku would win the rivalry because theres no fucking way that a bow and arrow could win against a trained soldier holding an AK 47.

But he digresses, Bakugou striked again, and now his notebook, the one he was using to copy the other's him handwriting, was in a fish pound, being eaten by... some kind of fish he couldn't recognise, sue him, there were no fish in his dimension, the only ones he's seen were fish demons, and those were horrendous.

Izuku dosen't know how many time he spent there staring at the fish, analizing the patterns on their skins, but it was time enough for Bakugou to already be out of his club activities and stare at him for some seconds from afar with what Izuku could only recognise as guilt in his eyes, so Izuku grabbed his notebook as soon as he saw it, cuz fuck it, he dosen't want to remember that guy is a teenager, then he wouldn't be able to not feel guilty for hating that fucker.

(nevermind he's also a teenager himself, but he dosen't like thinking about his age, it makes everything more depressing than it needs to be)

 


 

Izuku walked slowly, he didn't exactly had a place to get to fast, besides, going home and coming across his mother (the other him's mother) was weird, she was loving and caring and kind and was always worried about him and his well being, now, he didn't care about the bitch that called herself his mom in his original dimension, but it was uncany to see that woman as anything but a war veteran with way too much sticks up her ass and not enough hangers to get rid of unwanted pregnancies, it was weird, but he menaged because the Inko here is nice enough to deserve it.

(to deserve her Izuku back, not some weird ex soldier pretending to be a dead teenager)

For a moment Izuku gets lost in his thoughts, for a moment he's truly calm... And then he hears Bakugou's annoying yelling and is pulled right back to reality, wait... Is that a hentai monster?

 


 

Bakugou was being held by some kind of gross sewer-like slime monster, and for a moment Izuku thought to leave him there, there were heroes around, even if they weren't doing anything, they would at some point, right?

But then he remembered what happens in hentai when slimy things with tentacles trap teenagers and froze half way through stepping away, he looked at Bakugou for a moment, a tentacle slightly touching the blonde's knee was enough for Izuku to run in Bakugou's direction.

Grabbing the sharpest rock he could find in the floor, he lauched at the hentai sewage's eye and started stabbing, he dosen't know how many times he stabbed or how much time he spent doing it, but by the time the heroes dragged him away from the villain, both him and Bakugou were covered in blood.

And now he was sitting with the heroes scolding him for being reckless, they clearly didn't have any experience with stopping hentai creatures from molesting teenagers.

"-you shouldn't hav-" oh, they were still talking, time to space out agai- "we had it all under control!!"

... Okay now he's pissed, and not in the wet way.

"all under control?" Izuku repeated quietly. "under control you say" he gets up from where he's sitting, glaring at the hero as if he had just killed Izuku's dog in front of him. "THAT LITTLE BOY WAS ABOUT TO BE MOLESTED!!!" Izuku screamed at the hero while pointing at Bakugou, of course, everyone froze at the comment, just as expected, heroes don't like facing reality.

"YOU WERE DOING NOTHING TO STOP THE HENTAI SEWAGE, I SAW THE PERVERT GOING UP HIS LEG, YOU CANNOT TELL ME YOU "HAD IT UNDER CONTROL" WHEN THAT KID WAS ABOUT TO EXPERIENCE FIRST HAND WHAT IS LIKE TO BE A FEMALE HENTAI PROTAGONIST, IT'S YOUR FAULT I HAD TO INTERVENE, NEXT TIME DON'T JUST STAND AND STARE LIKE A LITTLE BITCH!!" he grabbed his backpack and throwed it over his shoulder, then walked to a stunned Bakugou and grabbed him by the arm, dragging him away.

 


 

Unknown to him, an old man with blonde hair and heavy asthma was watching from afar.

'he's a little bit too violent... but it'll have to do'

the old man thought, slowly inflating as he took the shape of number one hero All Might.
