Devastated by the words of his idol All Might, the Number 1 Hero, Izuku Midoriya tries to end his life by taking a swan dive of the building he and his idol was on. As he closes his eyes, accepting his fate, he found himself standing on a building and facing The Prototype himself Alex Mercer. There Mercer told him he was Izuku's past self and he is willing to merge their souls to give the Blacklight Virus to our protagonist and letting it mutate into a quirk. With this new quirk, Izuku will prove to those who doubt him that he too can be a hero. Disclaimer: I do not own the My Hero Academia nor Prototype Franchises..

"Izuku Midoriya... why does that name haunt me? It's the only thing I can remember. And that gruesome image..." *Bang!* "MELISSA!!!!" "Who am I? Why can't I remember anything? And who is this "Melissa"?" Izuku Midoriya was not born with a normal life. Upon his birth, he was immediately diagnosed with a very powerful quirk that manifested during his infancy stage. The energy it produced was too much for Izuku to handle and would most likely kill him of not handled right away. Izuku's father, Hisashi Midoriya, worked with the Shield family to limit Izuku's power in small amounts so that the power will never harm his body. However, years later, word got to the government that the young boy possessed such great power and they wanted to use it for themselves. They raided the base that they were healing Izuku at and killed everyone there including Hisashi and the youngest Shield child: Melissa all to capture Izuku to steal his powers. However, Izuku managed to escape with his mother, Inko, and they managed to live their lives far away from the government as they could. Inko made Izuku promise to never use his powers in public unless he was necessarily prompted to making him appear to be quirkless. However, during an incident with the sludge villain, Izuku used the full extent of his power to eradicate the enemy. The excess energy damaged Izuku's body initially until he eventually adjusted to the power itself, but he wasn't left unscathed. Izuku was left with a major case of amnesia and can't remember a single thing. At the same time, the Government found Inko and killed her for hiding Izuku. Now, Izuku has to fend for himself and the power he wields so that no one will ever use it for evil. It was a race for the ultimate power, of the Ultimate Lifeform.

In a world filled with people with an 80% chance to gain superhuman abilities known as quirks, Izuku Yagi found out at such a young age that he is part of the remaining 20%. He was quirkless. Powerless. Useless. Throughout his childhood, he was picked on by his childhood 'friend' and sister for dreaming to be a hero. Time passed, and he stopped dreaming of becoming a hero and decided to just be a normal person. That lasted until he was bitten by a radioactive spider, acquired spider-like abilities, and was proclaimed dead because of an accident. Standing back up to his feet, he promised himself that no one would experience being as helpless as he was before the accident. Clad in a skin-tight suit, he used these newly acquired abilities to save and protect, all while knowing the limit of his abilities. Because with great power comes great responsibility. Watch as Izuku uses these abilities to become the hero that he dreams to be, even if it is not so legal. This is the "Spider of Mustafu."

After his encounter with All Might, what if Izuku Midoriya was devastated that he decided to take a turn on an alleyway on his way home? What if he got caught in a chase and was taken as a hostage? What if in his attempt to escape the villain's grasps, he touched the man's hand and saw his memories before passing out? What if he woke up to know that he became a conduit? With the help in training from Delsin Rowe, witness as Izuku proves them that he doesn't need a quirk to become a hero. Disclaimer: I don't own My Hero Academia nor Infamous: Second Son.
