Authors Note: Helloooooooo Everyone! This is my first time posting a fanfic up here and I've been dying to actually try to do so. Anyway the other day I was reading No Hero Academia (Raizen1125), Acidic Affection (12AngryMen), and, my personal favorite, Awkward Energy (QuirkQuartz), and I thought that maybe I should give this a try! I mean I honestly like all these fanfictions, but I'm just a casual writer, who does this stuff for fun. But i honestly want to know where I stand in all of this, and so I need your guy's thoughts and comments on this, any criticism would do. I also run into points where I run into problems, like one with Mikumo's Pairing (Author's Note at bottom for details), but i digress. Anyway I will be needing your help to keep this story, and any others i come up with going, especially when it comes to big decisions, the more opinions the better! Aaagh! I've rambled on for long enough, god's sake I'm becoming like Izuku, so anyway, Here is Viral Toxin Chapter 1: Toxic Encounter! (BTW, I'm going to try and make each chapter title a pun, give me your thoughts on it^^)
Chapter 1: Toxic Encounter
Izuku walks home from school as he looks down, having been bullied once again by his bully/friend, Katsuki Bakugou, and he is covered in burns and bruises, the young boy trying to hold back his tears as he makes his way home. That is when he notices something in the sky, something shining in the distance, and it rapidly grows brighter. Much to Izuku's horror, he realizes its a meteorite and begins retreating to find cover, then covers his ears, bracing for the impact. It eventually comes, and causes a rather large crater on the road it is on. Fortunately, Izuku was able to hide behind a bridge and was saved from most of the impact, and his covering his ears prevented any lasting damage, only giving him a slight ringing in his ears. "What was that?" Izuku asks, looking to find the crater, and something is in it. What the young boy finds is shocking, a large meteorite, and the outer layer is rather soft, surprisingly, revealing an egg underneath it. The green haired boy's first instinct is to drop it and leave it for the heroes to find, but another part of him feels that if a villain finds it, this could only mean trouble. So against the young boy's better judgement, he stores the egg in his backpack, using his uniform's blazer to provide cushioning to protect the helpless creature inside.
Unbeknownst to the kind hearted boy, the young creature inside is conscious and can hear him, and even see him past its egg, noticing the great care he is putting in to protect it. "You'll be fine!" Izuku says, "Now let's get you to my place!" Izuku continues on his way, as if nothing had happened, only for the heroes to appear just minutes later to understand the damage, whilst scientists gather the pieces of space rock, which have hardened by now. Once home, Izuku's mother holds him close, crying as she had been worried after the news report had explained what had happened. "I'm fine mom, really, I managed to notice the Meteor coming my way and took cover before the impact!"
"Oh thank goodness!" Inko says, shedding tears as she lets go of her son. "You must be exhausted after that event, so please, go upstairs and relax, I'll make some Katsudon for dinner!"
"Alright!" Izuku says, smiling as he goes to his room, being careful of the egg he is hiding in his backpack. He quickly changes out of his uniform and into his casual clothes as he takes out the egg and begins to wrap it up in his blanket, smiling as he looks at it. "There you go, little guy! Nice and warm!" He has swaddled it like a baby, an he puts it on his pillow, smiling big as he looks at it. "I hope I can find out what you are soon!" Izuku is smiling but then he notices something, the egg has started to move and then it begins to crack. "Whoa! This is sooner than i expected!" Izuku starts to panick as the blanket comes undone, and the egg cracks further, revealing a hunter green ooze inside. The young boy is confused but his curiosity gets the better of him, to which he gently reaches inside and touches the ooze finding it is rather sticky, however, instinctively, Izuku can tell this stuff is alive, and he desperately struggles to remain calm.
Hello Izuku…
"What…? Who said that?" Izuku asks
I did! I am the spawn you had touched inside this egg.
"Who are you?"
I have no name, I wasn't given one. But aside from that I am a Klyntar, a member of an elite warrior race hellbent on protecting the innocent and upholding justice, which does this through symbiotically bonding with a host who is strong of will, pure of heart, and keen of mind.
"Amazing!" Izuku says. "Hey… Is there any way I could become a hero?"
Everyone has the potential to be a hero, but it takes one thing that truly defines heroism, the trait of Self-Sacrifice, the willingness to put other lives before your own. Izuku, I can see into your mind and I know you are one of the few people who are Quirkless, those born without powers, and yet your admiration for All Might and his selfless ways of a true hero are what you aspire to be, and I can give you the power to save others, but you must remember one thing.
"What is that?"
With great power, comes great responsibility, remember this, for it will remind you of your duty and keep you from becoming corrupt.
"I will!" Izuku says, smiling but then looks at the Klyntar Symbiote, "So what do I name you?"
Give me a name that will inspire hope in those who see you as a hero, but also fear in your enemies, one a warrior of justice will use.
"Then how about…" Izuku thinks, and smiles as he remembers something. "Hold on a minute…!" He detaches from the symbiote and rushes to his computer, looking up Spider Man, one of the Original 6 heroes who appeared in the world, brings the egg to reveal the Black Suit to his friend.
Grandfather!
"Grandfather!? You mean the suit?"
Yes, that is my grandfather, Venom! nearly 135 years ago, after Spider Man's death, he found a way back to Planet Klyntar through the use of an ally's Warping Quirk, and he lived there until his death, eventually spawning a violent serial killer named Carnage, my father, who was corrupted by the violent urges of his host, Cletus Kassady. However, before I hatched, my grandfather, alongside his new partner, found me and brought me back to Klyntar and i was purified of my father's violent urges, and at my grandfather's insistence, he had me sent here to find a partner to continue on his legacy, passing on all of his original partner's power to me!
"I see…!" Izuku says, smiling at the symbiote, "Then I think i have just the name for you!" He brings up the wikipedia page on the comic books made about a fictional symbiote of the same bloodline, Toxin. "Toxin, named after your fictional counterpart!"
Toxin? Yes, it reminds me of Grandfather's name, Venom. I approve, together we are Toxin! The symbiote then flows onto Izuku and begins wrapping around him, becoming a sleek, skin tight, hunter green costume, inspired by Spider Man's suit, with the lips and fangs of his comic book counterpart, as well as the large eye lenses, and retractable claws. What do you think, Izuku?
"This is awesome, Toxin!" Izuku says, smiling. "Though question… What do you eat?"
I'm a Hormonovore and Proteinovore, I basically subsist off of the hormones and excess proteins your body both generates and intakes. Though my grandfather did give me a piece of advice for living here on Earth, and said that chocolate, sausages, cheeses, and a select number of mushrooms are foods that carry our most vital protein, Phenethylamine. He and Spider Man discovered this and when he returned to our people, he spread this knowledge amongst us and our hosts, making it easier on all of us, as one of biggest problems was getting enough Phenethylamine to survive just for one day, and we had to make our hosts go through severe training regiments just to feed us.
"Yikes…"
Indeed, but in any case, you will need to strengthen your body before I can pass on Spider Man's gifts to you, so please prepare yourself for the struggles ahead, but know it will all be worth it in the end.
"I agree, Toxin, lets get to work!" Izuku says, smiling "So how do I actually take you off?"
I will simply recede into your body, we are now bonded on a cellular level, but my own coloring shouldn't affect your skin tone in any way! If your mother does notice any sort of changes, simply tell her your Quirk finally woke up!
"Alright!" Izuku says, smiling as he feels Toxin receding into him, the young boy smiling as he looks at himself, looking at himself in the mirror and noticing nothing has changed. 'Good mom shouldn't notice…'
Hopefully… However she is quite in tune with you!
'Are you speaking with me telepathically?'
Yes, for the lack of a better term. Though it will leave your eyes glazed over a bit, as if you were staring off into space.
'Good to know, thanks Toxin!' Izuku thinks.
I should also warn you that I am not the only Klyntar that was sent to earth, I have a cousin here on Earth as well, and it was thanks to him, my grandfather found me. He was sent to Earth ahead of me in order to find an individual who fit Grandfather's criteria.
"Really?" Izuku asks.
Yes, and I can sense he has bonded with somebody, we're able to sense each other, and we're going to encounter them soon.
"I see! I can't wait to meet him!" Izuku says, smiling as he goes to the front room to watch some tv.
That might be sooner than you expect, Izuku.
Nearly a week passes as Izuku starts his training to become stronger in order to be able to utilize Toxin's powers, and thanks to his partner's tutelage, the two of them are making some genuine strides in Izuku starting to beef himself up. However, on the last day of that week, Izuku sees somebody he hasn't seen in a very long time, his cousin, Mikumo Akatani. "Mikumo!" Izuku says, rushing to his cousin, the red haired, blue eyed, cousin looks up, stunned to hear that voice.
"Izuku!" Mikumo says, rushing to his cousin and the two hug each other. That is when Izuku and Mikumo look at each other and a red Symbiote face appears out of Mikumo's back looking at him. "Is something wrong, Virus?"
Nothing is wrong, I can sense my cousin is here with yours!
"Toxin, is that the cousin you were talking about?"
Yes it is my cousin, and it seems he has the name Virus now. It is good to see you again, cousin!
Agreed! I am overjoyed to see you made it to Earth safely, Mikumo and I were looking all over the city for you for nearly a week!
Well I am just glad you made it safe… Anyway, Izuku and I were doing some training, if you wish to join us, we could use a sparring partner!
Sounds like fun! What do you two think?
"We're in!" Both cousins say, smiling. And over the next 4 years, the two boys train hard and eventually become perfect hosts for their symbiotes. They also discover quite a few differences between their Symbiotes, in which Toxin prefers a fighting style that is is all about speed, flexibility, and strategic planning, Virus prefers a style that is just pure brute force. However, the two of them are able to work out these weaknesses with each other through conversation between them and their Klyntar Symbiotes. Meanwhile, in Izuku's school life, he has begun to fight back against those who had been oppressing him all these years, especially against Bakugo, however, it is on one fateful day that Izuku finally snaps.
Bakugo burns Izuku's Hero Analysis for the Future, and Izuku recovers it quickly, but then gives Bakugou a glare with hate in his eyes. "You know what, Bakugou, I've put up with you until no because I thought you were my friend. However, you've finally crossed the line!" Izuku says, gloves made from Toxin's body begin to appear on his hands. "I'VE HAD IT!" Izuku shouts, catching the attention of the nearby teachers and students as Izuku lunges at Bakugou and the two begin fighting each other. Izuku swings carefully aiming for his former friend's stomach, sending a kick at his target, to which Bakugou glares at him angrily, jumping over the kick and backflipping over Izuku, aiming a blast for Izuku's face. However, Izuku just smiles as his spider sense tingles and he ducks under the attack, gets down on all fours, and lands a well placed nut shot with his right leg. There were two things that Bakugou didn't expect from this, one was the actual hit, and the second was the force behind it, Izuku had never been this strong before! "Alright, Bakagou, time for you to face nearly 10 years of Karma!"
Bakugo looks at Izuku with a glare on his face, "What is going on, Deku, how are you this strong!?"
"Lets just say I had a little help!" Izuku says, grabbing Bakugou by the neck and then tossing him into the wall, creating a crater. "And it's not Deku anymore… We are Toxin!" Izuku's voice switches to that of Toxin as he sees Bakugo glaring at him, though with a hint of terror in his eyes as Izuku begins to throw punch after punch at Bakugou, the Teachers and students horrified as Izuku unleashes hell upon the blonde bomber.
Izuku enough, he can't feel anything anymore! Izuku stops as he looks to Bakugo, seeing the boy is unconscious, to which Izuku tosses him aside, walks up to him, and spits on his face.
'That felt good…' Izuku thinks, 'But I don't want to feel that level of aggression again…'
Understandable, and now you know how corrupting the Anger Empowerment feature of my physiology is to use, and you should now be able to use it more wisely from now on. Izuku walks past the terrified teachers and students, who are now looking back, seeing how Izuku had been changing over the past several years, and now his boiling anger had finally reached its breaking point, causing every teacher and student to become terrified of him. The police get the story from Izuku, the teachers, and the staff, about what happened and how things got so far that Izuku cracked a few of Bakugo's ribs, broke the boy's nose, and left severe bruising on him. Izuku pretty much explained his Quirk was Anger Empowerment, and Izuku never brought it to bear on anyone, causing everyone to think he was Quirkless, and how he had finally snapped after all of Bakugou's bullying, to which the Police, and a few heroes, to realize this boy, despite his quiet and shy demeanor, had such a terrifying Quirk that he kept in control for years until he finally lost it. Despite this, the teachers also share the blame for having allowed Izuku to be bullied the way he was, even being part of it due discrimination against him. The Students, after being informed of Izuku's "quirk" are now immediately terrified of him, and are rather grateful that he only brought the hammer down on Bakugou, his biggest bully.
As Izuku walked home that day, finally feeling good about life, he decides to stop by the spot he first met Toxin, and the Symbiote feels nostalgic as they pass through the area. Only problem is that as they pass by a manhole, a green sludge monster begins to attack them, Izuku's spider sense activating seconds too late as the creature grabs him. "No!" Izuku says as his face is covered by the villain.
Izuku!
"Good now I have someone strong, I can face off against…"
"Worry not citizen!" A voice Izuku recognizes calls out. "FOR I AM HERE!"
"All Might?" Izuku asks as his mouth is freed.
Don't step into the Light Izuku, DON'T STEP INTO THE LIGHT!
"Hey Kid, wake up!" All Might says after capturing the villain and begins patting Izuku's face awake, the young green haired boy waking up a few moments later and soon shenanigans happen both of them ending up on a rooftop, to which he looks at Izuku after he says he has something to ask All Might. "You have something to ask me?"
"Y-yes!" Izuku says, nervous, but tries to keep calm. "I've been wanting to know if its possible for someone who is Quirkless like me to become a Hero!" Izuku then begins to ramble a bit as All Might begins to feel pain and steam flows from his body. "So I was wanting to get your opino-AAAAAAAH!" Izuku screams as he sees All Might transform into an emaciated man. "WHO THE HECK ARE YOU!?"
"I'm All Might kid…" The man says.
"Liar!" Izuku says.
"No kid, I'm telling the truth…" All Might says, showing Izuku a wound he has on his body, one caused by Toxic Chainsaw several years back. "So thanks to this I can't remain in my hero form for more than a few hours each day."
'That wound, can you do something about it, Toxin?'
I think i can, but its going to cost you…
'Thanks Toxin, just name your price and I'll pay it off as soon as I can.' Izuku thinks, smiling. "I think I have a way to fix that!"
"Huh?" All Might asks.
"Its a bit complicated to explain, so let me show you…!" Izuku says, placing a hand on All Might's wounds, and slowly something digs into All Might's flesh as a dark green liquid flows through the spider web patterning of his injuries, All Might getting ready to scream, but the liquid covers his mouth. "Don't scream, I'm almost done!" Soon Izuku withdraws the liquid back into his body and All Might is gasping for breath as the pain leaves him.
"What did you… Do to me!?"
"We repaired the damage done to your body, by injecting proteins and hormones into your body to cause your Progenitor and Stem Cells to rebuild your damaged organs, whilst removing the toxins from your body…" Izuku says, his voice mixing with Toxin's, both of them exhausted after doing what they had. "You should be back to normal in no time, with enough rest, food, and training, you'll be back to your prime…."
"I thought you said you were Quirkless, Kid!"
"We are Quirkless, but we had encountered an unexpected ally who wouldn't survive without a host, and so they allow us to use their Quirk in exchange for sanctuary and sustenance…" Izuku says. "In any case, you should be able to start training again in about ten months… Once your body gets used to having its systems restored again…" Izuku coughs and wheezes from the exhaustion. "Now about that drink you offered…" Izuku looks up with a smile on his face, to which All Might brings out the bottle of soda, and Izuku opens the cap and Toxin's face appears behind his head. "Here you go!"
"Thank you!" Toxin says, drinking the soda to restore some his strenght. "Still, i require more, and your payment in this is as many chocolate bars as you can afford!"
"I did promise after all!" Izuku says, smiling as he stands up and begins to wobble away. "Luckily i know a store nearby!"
"W-wait, kid! Whats your name?" All Might says.
"Midoriya Izuku, but you can call us… Toxin!"
"Well then Toxin, if you hadn't begun questioning me earlier about my weakened state, I may have said something traumatic to you, but now I can safely say that, as long as your partner remains at your side, you can be a hero!" All Might says, smiling at him, causing Izuku to smile a large smile with tears in his eyes.
"Thank you, All Might!" Izuku says.
You know, over these past 4-5 years, our bond has grown fairly strong, and as such, some of Spider Man's quirk abilities have been bleeding into you, so you may have developed a quirk through our time together!
'Really?' Izuku thinks. 'Awesome!' Izuku rushes out to buy Toxin his due, smiling big with a spring in his step.
"That kid's gonna go places, humility and great power are a rare combination these days!" All Might says, putting his hands into his pocket, only to find what was there isn't. "What!?" That is when there is an explosion nearby and he looks in shock. "It can't be!"
Meanwhile, Izuku is skipping down the street as he and Toxin sing happily in their heads about chocolate, only to hear an explosion nearby, and on instinct, Izuku rushes to the scene, finding the local area melted, and a gas tank having erupted due to coming into contact with a lit cigarette. Izuku looks in shock as the reporters say something about a middle school girl having been taken hostage by the villain, and the heroes are doing their best to save her but can't get close without getting burned by acid. Inside the Sludge Villain, the girl is crying as she looks to the heroes to save her, and Izuku, on blind instinct, rushes in, fully transformed in an instant. "GET YOUR HANDS OFF OF HER!" Izuku shouts alongside Toxin, the two of them rushing forward. All Might happens to be at the scene, and sees Izuku Transform, unlike everyone else, shocked at his actions.
"WHO ARE YOU!?" One of the heroes shouts, to which Toxin doesn't reply, and swings his arm outwards using his ability to shape shift to transform his right arm into a scythe, and with a swing, cuts through the Sludge Villain, causing it to fall backwards, releasing the girl as Tendrils pierce the slime and begin to pull on her.
"What the-!?" The girl asks. "Who are you!?"
"Just a friendly neighborhood spider man coming to give a citizen a hand!" Izuku says, smiling "We in particular are called Toxin!" Izuku then manages to grapple onto her, "Hang on!" He tugs hard on the tendrils but as he does so, his spider sense goes off at the last second as the Sludge Villain has already made its attack. However, after a burst of steam, Izuku sees that All Might has intervened. "All Might!"
"I had forgotten to thank you for healing me earlier, Toxin, so what better way than to helping you during your premature debut!?" All Might says. "True heroes all risk their lives for the sake of others, that is the test we are put through every day!"
"DAMN YOU, ALL MIGHT, TOXIIIN!" The Sludge Villain shouts.
"DETROOOOIIIT SMAAAASH!" All Might shouts, rushing forward as he slams a fist into the villain, setting the girl free as Toxin grabs her and uses his tendrils to hold them in place to avoid the power of the shockwave. The young woman looks to see some of Toxin's mask peeling away, revealing green hair, green eyes, and, in her eyes, adorable freckles upon his face. As the shockwave ends, the mask reforms, but the girl has engraved those features into her mind, her pink cheeks gaining a magenta color to it. As the Shockwave passes, Izuku withdraws his tendrils and gently sets the girl down.
"Are you okay miss?" Toxin asks.
"Yes, I am, thanks to you, Toxin!" She then smiles at him and bows to him. "Thank you!"
"It is no trouble!" Toxin says, to which All Might walks over and before the crowd, offers a handshake, to which Toxin gives before shape shifting again and flying off as the police arrive.
"Oh right, he's unregistered, so he would have to flee to avoid consequences for Vigilantism." All Might says. "Well I am glad to have seen your heart is in the right place Toxin, when you gain your license you will go far kid!"
Walking home, Izuku smiles as he thinks about the months ahead and gets ready to face the trials that are sure to come.
You know, you forgot about something…
"Huh?"
YOU FORGOT ABOUT MY CHOCOLATE!
"OH SHIT!"
