Chapter 1
A lanky man who had a blade instead of a hand approached a terrified young woman.
"Just give me what I want and I won't hurt ya."
He spoke not even trying to conceal the fact that he was lying.
"Oh god s-someone help me!"
The woman called out before the man rushed forward stabbing his blade hand into the wall beside her head.
"No one's comin' to help you girly so just give me what I want and you might get to keep both your hands."
He growled his putrid breath making the girl slap her hands over her nose.
"W-what do you want?"
She spoke fear making her voice tremble.
"Everything you have."
The man said a dark glint in his eye.
"Now just g-."
He tried to speak but was cut off by a massive hand grabbing his throat and letting him up.
"Oh what a nice little snack!"
And brought him face to face with a creature with black skin that constantly seemed to be moving. It's massive white eyes glared at him as saliva dripped from it's massive maw.
"We wonder which part of you will taste the best. The heart, lungs, pancreas, liver, or the ever tasty brain?"
The man with the blade hand did what was natural for him and began stabbing the shit out of the creature.
But this only seemed to amuse it.
"Hahaha you're only making us more hungry!"
It bellowed before it slightly lowered the man and opened it's maw. Unhinging it and easily bringing it down on his head.
Before swallowing him whole.
The creature turned to the still cowering woman.
"Burp you can go now."
It said as it turned away from her and started walking down the alley.
"W-Wait!"
She called out making the creature stop in it's tracks. Turning it's head over it's shoulder to look at her.
The woman quickly scrambled to her feet.
"C-can I know the name of the hero who saved me?"
Her comment seemed to make the creature snort.
"We are no hero."
It said turning fully to her.
"We are Venom and we are the monster you need."
It said before turning once more and leaping up to one the sides of alley. Quickly scaling the building to reach it's roof.
The woman watched him go.
"You're a hero to me."
She whispered as she watched the dark form disappear into the night.
Izuku threw his sweat soaked shirt onto the floor of his mostly empty room and collapsed onto his bed.
"We really need to stop going out at night."
He spoke his voice muffled by his pillow.
'Why?'
Came the ever present voice of his other half.
"Well for one."
Izuku turned around to lie on his back.
"The entrance exam is tomorrow and I need plenty of sleep."
Venom scoffed in the back of his head.
'We can complete whatever worthless test those heroes have for us in our sleep.'
The greenette groaned in annoyance.
"I'd prefer to do it awake if possible."
Izuku said crossing his pale arms.
'Tch fine but you owe me extra food for this boredom.'
The greenette smiled slightly.
"I knew you'd say that."
'No you didn't.'
Izuku turned back around burying his face into his pillow.
"Figure of speech."
He sleepily said before the oblivion of sleep slowly claimed him.
And the memory of how he and his "quirk" met.
Izuku had been heading home. As he went under a bridge as he normally did something latched onto him.
Where in one universe it was a villain whose quirk made his body into sludge. In this one it was a tiny bit of black goo that stealthily made its way into his body without the teen noticing it.
Izuku headed home but stopped before he opened the door of his apartment.
"Maybe he was right."
He quietly muttered to himself looking at the railing that was in front of his apartment's door.
"Maybe I should end it all."
The greenette walked to the railing placing his hand onto it.
Before vaulting over it. A sad smile on his face as he did.
Only to stop before he fell.
"What!?"
He panicked twisting around. Panicking further when he saw the strange black tendril that had emerged from his foot.
'Stop moving!'
Yelled a deep voice in his head.
"Who? Who the hell said that!?"
Said voice had the opposite affect making the greenette panic even more than he already had.
'If you don't stop moving you'll die!'
"That's the idea!"
He called out trying to pull himself away from the tendril.
'Stop that dammit!'
The voice yelled before similar black tendrils spread down his arm before his fist slammed into his own face. Knocking the greenette out.
When he woke he was back on his bed. Questioning if what had happened had been a dream.
'It wasn't.'
Until that voice spoke.
"Ah!"
He shot upward in his bed looking around.
"Where the hell are you?"
He questioned looking for the origin of the voice.
Until those black tendrils emerged from his shoulder. Wrapping together forming a long neck and a strange head.
"Right here Izuku."
The boy flailed back against the wall of his All Might themed room.
"W-what are you?"
He whispered his voice filled with fear and confusion.
"I am Venom and you are my ride."
The greenette looked at the creature.
"What?"
It's ever constant smile seemed to grow ever so slightly.
"Call me a Symbiote. Think of this as a symbiotic relationship."
The boy leaned forward looking at the face.
"What do you mean by that?"
He asked his arms crossed.
"I decide what foods you eat and get some of their nutrients and you get access to powers a quirkless like yourself would never be able to have."
Izuku quirked a smooth green brow.
"Powers what powers?"
It's smile seemed to grow.
"My species have a genetic memory. Meaning whatever hosts we take we'll get a copy of their natural power. And our current host will be able to use said copy."
Izuku leaned back his back meeting the wall.
"And you'd give me these powers... if I eat what you want?"
The head nodded.
"Yes and I have quite the appetite little Izuku."
Izuku stuck out a hand.
"So I guess we're partners then?"
The tendrils that made up the head and neck extended down Izuku's other arm. Before it was brought upward shaking his hand.
"I suppose so little host."
