Can I be a hero if I'm a great old one?

Aka BNHA: Great old one

So this honestly is a short (so far) fic I had wondering around my head for a while now, I have no idea if this will continue or if this will be a one shot, feel free to use it as a story starter too if you like, just put in the comments when it's up or PM me, love these kinds of fics and frankly I've been wanting to do a parallel story for Darkest Hero since chapter 8.

Basically this is more of a pure BNHA/Lovecraft compared to my darkest Hero fic and will forgo any Hazbin Hotel at this stage and asks the question what if Izuku knew he wasn't human from the start and if Hizashi was a decent dad but also AFO?

"who?" normal speach

"GW8H2NS9U2S" great old one speach

"DIE!"shouting

Chapter 1: New student

Izuku was normal. Yes he was thank you very much and anybody who says otherwise was to be ignored, yes sir, no otherworldly things going on here at all. This mantra was a rather common one to be repeated through the minds of those who noticed anything off about the kid, wether they were aware of such thoughts or not.

Not for the first time in his life Izuku was cursing out his parents. His father for falling for his mother and his mother for being a great old one. Then again he also cursed his father for being a idiot. Hizashi Midoriya only really caught the attention of his mother through dint of accidentally achieving immortality during the his early 20s somehow. He didn't like to talk about it beyond it costing him his brother who opposed his ideas after a family feud. He only knew that he looked like his uncle and for some reason white hair ran in his father's half of the family, his father was on a business trip to America most of the time for work and apparently he had to have facial reconstruction done after he got into a car crash. His mother had shown him the pictures and honestly, his dad now looked like a weird baked potato.

He had no clue how he was even a functional member of society at this point given his father was a complete moron or absent while his mother wanted to eat half of the world's problems to solve them.

Putting aside his internal cursing Izuku made his way to Aldera Highschool, as he walked through the gates he sighed as he noticed his blonde haired and red eyed friend Katsuki Bakugo storm across the yard towards him.

"Oy! Deku you're doing it again!" The blonde snapped as he cuffed Izuku upside his head. "Walk ON the ground, not in it!"

"Uh? Oh, sorry." Izuku apologised, his feet which he hadn't noticed burning through the ground suddenly stopped burning as he stepped onto the propper ground level.

"Damned nerd, hurry up and don't do weird shit." Bakugo huffed as he stormed off for class.

"Wait up Kaachan!" Izuku called as he briskly walked after him. Admittedly he did have a small amount of trouble with the stairs but that was more he was in a rush and almost fell off the stairs but grabbed the handlebar and shimmied his way up instead. The one teacher who saw him just rolled their eyes and continued on their way, nobody was going to bother trying to stop him given it was normal for Midoriya to slip on that particular set of stairs.

Finding the correct classroom Izuku opened the door and sat down at his desk, most of the class was already chatting amongst themselves and a spare seat was still empty from the start of the year. Apparently some kid had a quirk that let them see in all spectrums, took one look at Izuku and ran for it. The mere thought made Izuku pout, he was human enough, even his form most couldn't see was humanoid, albeit a glowing green humanoid containing various galaxies which were constantly burning for all of time and space.

"Dude check it out." One girl snickered softly to the boy with a pencil head next to her, soon he too was laughing softly.

"SHUT UP EXTRAS!" Bakugo snapped.

"Uh jeez. Sorry." The girl uttered as she tried to cover her laughter.

"Kaachan they put the sign on you again." Izuku spoke up. This seemed to happen once a week on average and frankly it stopped being funny after the third time and now only served to annoy Bakugo.

With a snarl Bakugo ripped off a piece of paper from his back, this being a picture of his face Photoshopped onto a small Pomeranian. "ALRIGHT WHICH OF YOU FUCKERS WANTS TO DIE??"

"Alright class settle down." The teacher droned as he entered the room, a stack of papers in his hands which he quickly set aside on his desk. "Today we have a new student so I want you to give them a warm welcome!"

"Yes sensei." The class droned in boredom, the man could turn a damn arcade into a boring place to be and nobody was sure if it was his quirk or his personality.

"Good. Come in now." The teacher called. The girl who walked in had bright pink skin with curly pink hair and a pair of yellow zigzag horns atop her head. Her eyes were black with bright yellow pupils much like a raccoon. To most of the class this was completely normal, for Izuku however he instantly noticed the miasma around her aswell as how her eyes looked to contain galaxies and her teeth which appeared human were razor sharp and too numerous to be possible.

"Hi. I'm Ashido Mina, nice to meet ya!" The pink girl grinned cheerfully. "I like dancing and horror movies, I hope we can get along!"

"Right, sit down next to Midoriya please. Midoriya raise your hand would you? Your actual one not the weird creepy one." The teacher asked.

"It's all good, I kinda figured where to sit." Mina grinned as she sat down between Izuku and Bakugo in the empty seat. "Sup."

"Uh hey." Izuku nodded.

"H8AJ2BROAIB3FKEJWA?" Mina asked, the class recoiling in pain from the sound as blood trickled from their ears and noses.

"Just me." Izuku replied in a more mortal friendly language.

"Fucking raccoon eyes!" Bakugo snapped as he pulled some wipes and tissues from his bag to clean up the blood. "USE JAPANESE NOT OLD ONE!"

"Ugh not another one." One boy groaned.

"Ah yes, the why boner." A skinny kid with long fingers uttered.

"Gross Yaji." The pencil headed boy uttered in disgust.

"Uh..." Mina gulped.

"They know." Izuku shrugged. "Mum slipped something into the bake sale Last year, they can hear it but can't properly comprehend it, they also sometimes catch glimpses and it scares the hell out of them."

"I see." Mina gave a nervous chuckle.

"Perfectly safe, just uh stops them going mad for the most part." Izuku chuckled slightly.

"Fucking nasty piece of shit though." Bakugo scoffed.

"Bakugo don't disrespect Midoriya's mother, I happened to of liked her cooking." The teacher hummed as he continued to sort out the paperwork, ignoring the blood stains on the collar of his shirt.

"It tasted like how surströmming smells." Bakugo deadpanned. "I've seen you eat twelve year old fermented bananas with prawns sensei you can't talk."

"Yeah mum can't bake." Izuku agreed. While he did mentally curse his mum for her...hobby, he couldn't fault her on trying to be a good parent or her ability to cook katsudon.

"Never the less." The teacher replied as he finished sorting the papers. "Today we have maths first up."

"dad kill me now." Mina groaned as she slammed her head into her desk.

"I refuse." A raspy voice echoed with a chuckle.

"Smartass." Mina huffed with a roll of her eyes.

Ignoring the implications of the interaction, the teacher continued on with the lesson until it was time to break for lunch. The second the bell rang several students including Mina started to pack up.

"The bell does not dismiss you, I do!" The teacher snapped.

"Every time." Bakugo growled softly. "Stupid extras need to learn sensei is a control freak."

"Then why do we have the bell?" Mina asked with a curious expression on her face, part way between confusion and indignation.

"I want you all to be back here right after lunch for your careers studies, no dilly dallying!" The teacher snapped. "Now dismissed!"

"Alright Raccoon Eyes, you stay near me and Deku, we'll show you a good spot for lunch." Bakugo barked as he stormed off.

"Sorry about him, he means well but he just has trouble expressing it." Izuku explained as he slung his bag over his shoulder.

"Hey no biggy." Mina grinned back as they left for the cafeteria. "My dad may be a asshole to like 90% of the world but he cares... unless your a cultist he hates them for always interrupting his naps."

"I know the feeling." Izuku chuckled. "They seem to bug mum on occasion, never seen her as mad then the time they interrupted the season finale of some romcom show she got into."

"Sucks to be them I guess." Mina snorted as they continued through the hallways of the school. "So what exactly is the whole thing about here anyway? My last school I accidentally drove a teacher mad yet everyone knows about you here?"

"Sort of." Izuku muttered as he messed up his own hair. "Asides Kaachan I don't think anybody here knows about what I really am beyond something that isn't human, even then aunt Mitsuki is mum's priestess even though they act more like friends than anything so maybe the blessings of not going mad had passed onto Kaachan or maybe it's prolonged exposure to me or maybe..."

"Chill green, you're gonna mutter a hole in space time if you keep that up." Mina chuckled with a smirk causing Izuku to blush in embarrassment.

"It was one time." Izuku muttered softly, how was it his fault that he could do that? He didn't even know he could do it until his mother started using the rip in spacetime as a trash can.

"Pft." Mina snorted a chuckle as they arrived in the cafeteria and a smell reminiscent of anchovies fried in old socks filled the air.

"Oh no." Izuku's stomach metaphorically dropped at the sight before them, the school chef was experimenting again. This week? Anchovy toasted cheese sandwiches.

"You know what. I am not hungry." Mina frowned as her nose scrunched at the smell. "Smells like a shoggoth let one rip."

"How do you even know what that smells like?" Izuku asked in mild concern.

"I used to visit Denver as a kid with my parents. Kinda just ran into one." Mina shrugged as they made their way over to Bakugo who was in the corner of the room, as far away from the serving station as possible without leaving the room.

"Hurry up and sit your asses down." Bakugo snapped as he pulled a pair of Bento boxes out of his bag. "The hag made me take an extra for you Deku."

"Thanks." Izuku nodded as he accepted the container and opened it up to find charcoal covered chicken and rice. "Say thanks to aunt Mitsuki for me when you get home."

"Whatever." Bakugo scoffed as he pulled open his own box to reveal a spicy stir fry covered in Carolina reapers.

"Want some?" Izuku asked as he pulled out his own lunch to reveal his favourite food, Katsudon.

"Nah I don't think I can given the smell from the chef." Mina shuddered. "How did you even know green needed more lunch?"

"The old hag sees shit sometimes." Bakugo shrugged before he viciously bit into his stir fry, uncaring of the burning heat of the chillies in it. "Sometimes it's places, sometimes it's random bullshit."

"Huh so a low level seer?" Mina asked with her head tilted to the side slightly. "Neat, I mean I make acid and I can chew through almost anything but that's basically it."

"I just burn things." Izuku shrugged, a small gout of flames visible between his lips as he blew on his food to heat it up.

"Damn nerd quit being meek!" Bakugo snapped as he slammed down his food. "The nerd here is able to go against twelve shoggoths and come out winning, so quit selling yourself short as it makes me look worse!"

"Uh what?" Mina asked in confusion.

"The nerd here beat me at arm wrestling, if he says he is weak it makes me look like a damned extra!" Bakugo snarled.

"It was one time." Izuku sweat dropped in embarrassment, his expression drooping as he remember the damage he did to the table.

"SHUT UP AND EAT YOUR FOOD DEKU!" Bakugo shouted before stuffing his face with as much of his spicy stir fry as possible.

"He also gets super competitive." Izuku chuckled nervously.

"No worries, had a friend at my old school like that, he kept going on about being manly, last I saw him, he dyed his hair red in honour of Crimson Riot." Mina shrugged as she pulled out a cellphone and showed them both a picture of a red haired teen in a school uniform, his skin jagged and cracked like rocks and his hair was spiked upwards like an explosion. Izuku raised his eyebrow before shrugging, Bakugo however scoffed dismissively but a faint blush was seen by Mina across his cheeks.

"Crimson Riot is the hero from Kyoto isn't he? The one who can propell himself at mach 2?" Izuku asked.

"Shitty ass hero probably is only good at running." Bakugo scoffed in dismissal of anything to do with a hero other than All Might and maybe Endeavour.
