Introduction
If you want to read the story and don't care about why and how and any other author's ramblings you can skip this and go to Chapter 1 below the line. This story will contain gore and gender bending of sorts (main OC) so if you are not fine with that stuff , don't read this story at all.
I have never written as story before so expect some awkward formatting, messy story line and things like that, furthermore English is not my native language so the story may be full of grammatical errors (spell check helps but doesn't solve all the issues). The reason why I'm writing this is because I got bored waiting for updates on OPM fanfics I was reading and started writing down a random idea that I had. Before I knew it there were already few chapters so I decided to upload them, maybe someone will like it or just read them to kill some time before their favorite OPM story gets updated.
I plan to follow the story of OPM and insert my OC into it, some parts of OPM will be skipped or shortened and few new enemies will be added for OC to fight (OPM characters may enter the battle as well). The OC is overpowered, not as strong as Saitama but should be able to handle other S class heroes (eventually). I plan to get some romance between OC and Fubuki but not sure if I can pull it off. If I don't drop the story I may even add Saitama/Tatsumaki romance to it (since I will follow OPM they will not meet until very late in the story)
I don't own any OPM characters and may incidentally use some OC or monsters from other fanfic (sorry). It's sometimes hard to tell if the idea is mine or if I just remember someone's fanfic , but the main OC should be completely mine.
If you have any ideas or complains feel free to put them in comments, though I can't guarantee I will read them (no idea how long I will keep with this story). As for story updates, they will be sporadic and random (5 updates a week, 1 update in 6 months, who knows?) I will write this when there is nothing else to do and I feel like writing this.
I have no idea how long a chapter should be so they may be too short or too long. And I may use a wrong point in the story to split the chapters as well. I'm not a writer and I don't plan to become one. I'm doing this because it's fun.
Few notes on the style I will try to use (not sure if I can follow consistently)
Bold letters are for loud voice
UPPERCASE IS FOR MONOTONE ROBOTIC VOICE
BOLD CAPITAL LETTERS FOR SCREAMS
Italic is for weak voice or whispers
() round brackets are for thoughts
[] square brackets are for robotic thoughts, like a program doing something with no visible output
"Text in apostrophes is spoken out words, when people are talking"
this format is for change of POV, time, place change, short explanations, etc.
- And these are narrator comments, to explain something, because I felt like explaining -
Chapter 1: Incident
EXPLOSION. A giant crater covered in rubble appears where houses once stood. In the middle of the crater stands a tall purple being, humanoid in appearance with two antennas on top of its head. The being flies up and several energy balls appear around it. As it swipes its hand the balls follow the motion flying towards building, exploding on contact and destroying them.
In city Z a bald man watches the news about the explosions in the city when the video feed turns to static. (Guess I should go) thinks the man.
As the purple being walks around the ruins in the city destroying buildings left and right it notice a girl crying. The being raises it hand gently towards the girl, then the hand turns into a claw and squishes the girl. Or so would it seen, but before the hand closes there was a yellow flash and the girl can be seen several meters away from the being. The purple being only notices this once it opens its claw and finds it empty with no blood or girls remains on it.
Next to the girl a bald man wearing a yellow jumpsuit, red gloves and boots and a white cape can be seen. "Who are you?" asks the purple being. The bald man smirks and replies. "Just an average guy who serves as an average hero." This pisses the purple being . "What an half-asset back story is that!" "I, on the other hand, was spawned by the continuous pollution of earth cause by you filthy humans."
"I am vaccine man." "Mother earth is a life form itself and you human scum are nothing but a virus eating away at her life energy." "I was born to wipe you humans and your evil civilization from the face of earth." "I am the wrath of mother nature incarnate!" screams vaccine man as spikes begin to grow from its body and his fangs and claw grow larger. "But you! You're what? An average hero?" "You dare to oppose the nature's apostle for that reason?" vaccine man angrily asks as the bald man just stares at it with a bored bland face. "There is no other cure for the human virus …" "than to exterminate each and every one of them!" shouts vaccine man with its grown bulky body, large fangs, claws and spikes.
Bored with the monsters constant rambling the bald man casually punches it. The monster explodes. The bald man looks at his hand, evidently annoyed, and then he lets out a desperate scream. "Another fight that ends after only one punch." "Fuuuuuuuuuuuuck!" After a short time the bald hero regains his bored expression. "I guess I'll go home."
few minutes ago, in the same city
In a small lab an old scientist looks at the monitor with high expectations. Finally a message appears.
"FINAL CHECK COMPLETE: ALL SYSTEMS OPERATIONAL"
"All these years, thousands of different configurations, multiples of materials and many different algorithms. Failure after failure. But now, finally, a success!" he smiles gently double checking the results.
"All that is left is to transfer human bio-metrics, then I can start with trials." he types few commands on the keyboard and watches as the file transfer starts.
"I should start with some volunteers in critical state or maybe recently deceased (or not as it could be seen as unethical). Once people realize that the nanites are safe and can heal even the direst wounds we can move on to less critical patients." the old scientist walks around the lab and looks at the tank holding a metallic liquid as he talks to himself.
"No one will have to live in a wheelchair unable to walk or run. Loosing and arm will no longer be a tragedy, only an inconvenience." the old man glances on the screen as he talks to himself.
"DATA TRANSFER 70%"
"Just a little longer un-" EXPLOSION.
In the wreckage of the lab a gruesome sight awaits. A twisted metal piece poking from an eye socket of the old scientists, his torso completely missing, body parts spread across the ruble and droplets of the metallic liquid everywhere.
A sudden spark across some twisted wires reaches a pool of metallic liquid. The liquid flashes bright blue once the current runs through it.

The pool of metal glows brightly, it flashes several times. Droplets of metallic liquid all across the area start to glow in response.
The liquid moves toward the different pieces of the scientist, covering all of them, then small strands of liquid connect to each other and pull the pieces together.

AN: you probably figured this out, but the metallic liquid was made from nanites (microscopic robots) designed to repair damaged cells and organs
even without the human bio-metrics, the nanites would be able repair any damage but would not know how the organs are supposed to look and could end up with something different, it would work as well or even better than normal human organs but could look pretty crazy
primary bio-metrics are male (primary because subject is male) and secondary are female, and there is a separate set of data for each gender rather than a singe data set with a separate data for difference between males and females
