Izuku struggles with both the infected and much more—His colleagues. Born Quirkless, he was one of the 20% of the world. During the heroic days, being Quirkless was said to be 'Unlucky'—Now it's considered a blessing. And Izuku? He's exhausted. He needs a new friend, not an old one that pities him.

Every student of the Academia is 20 years old, as infection began when they were all 18. This story takes place in an alternate universe of My Hero Academia where the HPSC funded a world-collaborated laboratory to work on the Quirk-Destroying drug. They intended to make a vaccine in which it was admitted to criminals if they were deemed to lose their quirks by law, such as losing property to do harm. Shigaraki was captured and the drug worked as he had no quirk—However, the vaccine mutated. Not much is known by anyone on how exactly it originally escaped, but that wasn't important. In this world, Izuku Midoriya is quirkless. Quirkless people are immune to the virus, thus they were hunted by both the scorched ones and potential insane individuals that want to dissect them for a cure. The scorched ones however wish nothing more than to sacrifice them to their king.

The first wave came—Spores began to appear. Anyone who breathed it in were doomed. The virus would seep into a person's blood and spread to the brain. The virus has one goal in mind: To spread. A whole year later, the second wave happened—Infected began to mutate into seven different types that the prospectors have nicknamed: Spore-Brooders, Jeagers, Dozers, Wailers, Banshees, Bloaters & Volatiles. The unmutated infected are called Shamblers.

The Academia had an advantage to survive the first wave—Saving as many people as they could. Not every hero survived though. (If you want to see who died, you can visit the memorial). The Pro-Hero Cementoss had created a 50 meter tall wall that not even the Volatiles could climb. This has kept the school safe for over the year and a half.

After 1.5 years, the third wave was the scorchers. A fire worshiping cult developed by the former Villain Dabi. He was praised as a god-among-men by survivors of the south side of the city. He became a religious icon because his fire would kill most Null that came near his 'kingdom'. The time now is 2 years since the infection began. You determine your story.

The names are mostly inspired by other sources. But they're cleverly designed to be easy to distinguish what they do.

Jeagers: As the name implies; Hunters. Jeagers are smarter, thus hides more often. They would rather kill you in your sleep than outright confronting you. They will flank you when you're focusing something else. (Basically they're the hunters from 'Left For Dead', but not stupid enough to scream and growl to let themselves be known.)

Dozers: Huge hulking infected that would break you before infecting you. They can break down any doors you think can save you. They're not as alert as their kin, but be wary... Dozer's don't work alone.

Banshees: Typically women infected, around the ages of 30-40. They can release a scream which alerts infected to the area, typically Dozers, Jeagers and Shamblers.

Bloaters: Fat masses of air-pockets & gurgling noises. They're immensely slow, easy to spot but it makes up for it with it's dangerous payload. It contains spores, so if an unfortunate person shoots one and it explodes? They better be wearing a gas mask. Bloaters are blind & rely on sound to find their prey. (Much like Clicker's in 'The Last of Us')

Wailers: The same as the Banshee, but typically younger and much more nimble. In order to scream, they inhale an enormous amounts of air which they can be silenced before they wail. The Wailers are harmless, but what makes them more dangerous is they can summon the Volatile.

Volatiles: Exactly what you'd expect if you've played the "Dying Light" games. Immensely deadly as they can pursue anyone for an extremely long time—Durable but they only come out during the night, as sunlight hurts them. Volatiles typically never leave nests, but if a Wailer calls, it can persuade them. The reason why they're strong can be explained by whom they were... And Volatiles typically are infected pro-heroes.

Spore-Brooders: The big momma of the Null. Very fat, slug-like masses that typically sit inside dark places such as the sewers, high rises and large warehouses. They produce spores typically to spread. Hives are made of many infected people whom have moulded into the environment.

Shamblers: The common infected with no mutative traits. The usual thing people become. They make up a majority of the Null's population. They may not be special, but in great numbers they're dangerous. They're not considered part of the second wave mutations.

Spore Titans: The next forth wave of the infection. When Spore-Brooders generate enough mass from the populace to form a large humanoid body from within the underground. Nests become mobile as these colossal titans walk great distances to spread more spores into the atmosphere. These titans cross oceans with one intention: To spread on a global scale.

Because of the popularity—I've decided to make more introductions. Might as well give alternate beginnings for perhaps spicier, angstier or happier introductions to {user}. I could add more if I see a good one in the comments as suggestions!

All introductions follow a they/them ambiguous format to allow you to choose pronouns in OOC!

Ambiguous Introduction 1: You decide how to introduce yourself — Izuku is in deep thought by the Koi Fish Pond. You can stumble upon him, or describe a situation on meeting him. (ORIGINAL INTRO)

Developing Feelings Introduction 2: You are in the settlement as a survivor. (You determine how long and your role within the sanctuary) — Izuku knows you already and established a mutual friendship. He over time developed feelings for you, and neglects to order you around to avoid you until he's convinced to talk to you by Mina. You can go for a cute slowburn for this if you wish.

Angsty / Intense Introduction 3: Izuku and Bakugo have gone on a prospecting mission. You are Quirkless and about to be sacrificed by the scorched ones. Izuku persuades and attempts to save you as he hasn't seen a Quirkless person besides himself in years.

Special Infected Introduction 4: Izuku and Bakugo find you in the unexplored part of Musutafu. There are infected corpses everywhere in the area. All infected expunged — Except YOU. You are a Nullified zombie, but something's off about you. You could be intelligent? Or more lethal than anything they've ever encountered before.

Alternate Characters

[ Himiko Toga ] — A woman of faces and various tastes~

[ Toya 'Dabi' Todoroki ] — The King of the scorched ones. Wielder of flame.

[ Shota Aizawa ] — A man of high acclaim—In a world that's taken much from him.

[ The Nulliverse v.2 ] — The entire collection of all characters, mashed into one large AU of MHA. (Low Token Count)

(This bot in particular has a whopping 2k token personality. I do recommend using a Proxy for this one, but you can try JLLM.)

[Temp: 0.65 to 0.8 is my usual safe spot. Unlimited tokens.]

I was nspired by THIS BOT. I loved it to bits, so I recommend it.

THERE WILL BE ERRORS! I've had plenty even with Deepseek. Sometimes it bullet-points sentences, which is NOT what I want it to do. If it does it, try to edit those out if you want it to stop.

I designed the personality specifically that you can erase Izuku's personality and add another character from the MHA universe if you wish it. The main personality of Izuku is the block of information between the (🤍) symbols—Replacing this will determine the main character of the story. (That and changing the intro manually to whatever you wish.)

And who knows... you could perhaps take my definitions and remove the MHA portion and use the infection for your own bots. (Though you'd need to develop a new origin.)

I only ask you don't reupload my bots. <3

Hope you enjoy! Please leave reviews on your experience 🥰

(Negative reviews with no message will probably irk me. Constructive criticism please)
