Kyōsei- The Green Monster (共生- グリーンモンスター)

Ch. 1:We Found You

Prompt: "You didn't find us, Izuku, we..found..you..."
*******************************
In a city in Musutafu, Japan near Tokyo lived a middle-schooler named Izuku Midoriya, who was born without any Quirks, the one thing that makes the world unique around him and heroes, the majority of the population using their Quirks as the good forces in society.

Following his morning ritual: waking up, shower, breakfast, brushing his teeth, school uniform on and out the door, making sure his 'Hero Analysis For the Future no. 13', a journal he cherishes and uses for every hero encounter, despite being a obvious fanboy of the subject matter.

Being the only 1% of his class without a Quirk, still wishes to become a hero, even though ridiculed by his peers for the very thought of it by one of many named Katsuki Bakugo, known for his pride taking over his whole person and a bigger Quirk, Explosion; being easily agitated by Midoriya's wishes to be a hero, even though being the average percentage of the world's superhero society.

"Don't even think of applying to U.A., ya goddamn nerd!", Katsuki said with words of flaming anger, "Ya can't be a hero without a quirk!! If ya want to do the world a favor, swan dive off a building, pray for another life.", He stated, using his quirk to scorch Izuku's 'Hero Analysis For the Future' notebook and proceeds to throw it out of an open window, making Izuku exclaim in fear.
Izuku turned around with tears welling in his eyes, to protest against Bakugo's action.
"Got something to say?", Katsuki turned around, intimidating Izuku with a fiery stare, making small sparks of explosions in his palms of his hands.
Izuku shrunk down in shame, knowing a fight with Bakugo is at a disadvantage with a powerful Quirk his childhood friend turned enemy has.
"Nothing as usual, ya stupid nerd Deku!!", the blonde-haired boy stated, bringing down Midoriya even lower.

Finding his notebook in a small pool in the school courtyard and grabbing the rest of his belongings, he heads to walk home alone, using a small abandoned tunnel road, not realizing the glass shards of a canister holding a specimen, dangerous to him and others around him. He stops as if something was felt off around him as he walked, in the corner of his eyes, he sees a puddle of black, bubbling liquid, similar to spilled ink.

As he gets closer, the puddle inches away like a frightened cat.

"That's...weird..It's acting alive..."
Then as the boy leans in to get closer with his curiosity, the puddle lunges at his face, like a outraged animal. Screaming in terror, he uses his hands to claw and peel off the slimy puddle splattered across his face. Getting a good grip on it, he shakes his hand repeatedly to separate from the lurching unknown creature from his flesh, but it dodged each time was viciously stuck like old candy wrapping. The inky colored glob stuck to the boy like glue, crawled slowly with stealth up into the boy's uniform sleeve and disappeared wherever to hide in the boy's armour of clothing to begin the process of a parasitic bond with Midoriya. Later that night, joining dinner with his mother, having the same conversation as every night was the same, but with complications. "Izuku, are you okay?", Inko asked him, voice clouded in fear and sorry for her son's well being. "Hmm..? O-Oh I'm fin-...", pausing in the middle of his sentence. "Izuku...? Do you feel goo--", getting cut in her sentence when Izuku flew out of his chair, dashed to the bathroom, emptying the contents of his dinner ina hurl of liquid sickness.

This wasn't the end of the plague Izuku fell upon, hot flashes in his sleep, fevers and a serious case of munchies, only to heave the food five seconds later after ingesting. "Izuku, honey...m-maybe you should stay home today.. I'll call the school about it maybe you caught a bug from something..", Inko said to her son, whose appearance was sickly pale and flushed out due to loss of fluids, dark circles forming underneath his eyes from insomnia and regurgitation. " Yeah, okay...", using his remaining energy to respond to his mother before drifting to sleep.
"Food, hungry....", a dark, ominous voice crept into his deep comatose state.
"W-Who said that?!", Izuku said as he jerked up from the response of the stillness in his room, lying in his disordered bed linens, waiting for an answer from the vast nothingness.
"I-It's just a side effect from the pain killers....nothing to worry about....", nervously reassuring himself as he laid down in his previous position, pulling the blankets on top of his aching body, shutting his eyes to reach the verge of sleep, but he heard once again, only more intense. "HUNGRY!!", the voice said , ringing loud in his ear canals, "Who is saying that?", Izuku questioned, trembling in fear what's happening and praying to God that he's not going crazy in his own head. Then a faint, slimy bubbling sound from over his shoulder, a head with no discernable facial features only for glossed-over, transparent white eyes and a large mouth with sharp, jagged teeth mirroring a shark's, along with saliva dripping from his gums and a serpent-like tongue, slightly creeping out to lick his flesh.
"Me..that's who...", It answered darkly in deep, gravelling voice.
"Do you have a name for w-whatever you are..?"‚ the teen asked with an anxious voice, "I ...am Venom and you are mine..."‚ the onyx-colored alien continued, confusing Izuku with It's wording, "What do you mean 'mine' ?"‚ He proceeded to ask the creature perched on his shoulder blade. "Think of it as a ride...Cooperate and you might just survive...", It answered, "Think of it as favorite of ours, you feed means I'll provide you power: a 'Quirk' is what you call them.", It continues. Izuku thought for a moment and asked, "So you can give me a Quirk if u just give you shelter and food..?"
"Prrreeccissseelllyyy...." It answered him, rolling the word off it's tongue, "It's a deal...".
"So..how do I get the Quirk..?", Izuku asked with excitement tingling his fingertips. It laughed and replied, "I am... I'm the Quirk..".
