Izuku Midoriya was crushed, if not entirely Broken. He always had a hope that even though he was quirkless. Then he met All Might and had hoped that he would say he could be a hero even though he didn't have a quirk. However, the truth had hit him hard, he can't be a hero without a quirk. Even All Might has said so after telling him how he could still help people and showing him the dangers of hero work. So Izuku didn't go towards the noise that he heard that seemed like explosions but he didn't care. He went the other way to stay away from it.

As he was walking, a group of men came behind Izuku until he was mostly alone. As he was walking he also saw a man in a green suit with a white tie with green buzz cut hair looking his way. He ignored all of this and kept walking until he went into a alleyway, with the group of men following him in.

That's when he heard the tallest and most musclen one of them speak. "Ok kid, we want you to empty your pockets and had now!" As the man said this Izuku turns to look at them with a look of horror and fear. He knew he could not defend himself so he tries to talk his way out of the situation.

"Sorry sir, I don't have anything of value on me. All I have his my school books and equipment. Also my phone and school ID but that's it, I swear!" Trying to make it seem as if he has nothing of value he opens his bag to show them what's in it.

This however doesn't fool them all, "ok kid, I know your lying!" Says one the shortest laky who has red eyes and pointy ears. Realisation hits Izuku like a truck, as he figures out this guy must have a lie detector quirk.

"Really Devil, well then let's teach him it's not good to lie to his elders." Says the leader as he suddenly gets even taller and starts to turn blue. While he is doing this, one of the other thugs who has red hair and eyes with black skin, starts to sharpen his hands into claws. The one they referred t as Devil steps back to allow his friends to do as they please. The last one however, who so far has done nothing but stare at Izuku, decides to finally speak.

"Sorry boys, but I have taken a liking to this boy. So now it's time to ditch this skin." While speaking, the man who once had purple eyes with black hair and pale skin starts to melt away. He then appears as a man who is taller than before, with a leather jacket with a high neck and a hoodie and jeans on. His face also changed, as before he was pale now he is slightly tanned and has red eyes but his hair is hidden undead the hood.

"Who the fuck ar…!" Before the leader can finish speaking, there's a massive blade going through his stomach, with his intestines spilling to the floor and blood spraying all over the alleyway, the other thugs just stare in shock at what just happened. The man, who feels very familiar to Izuku, then grins at the other would be thugs.

"So Devil And Claw, What you two gonna do now ha?" The man asks with a crazy going in his eyes. This scares both men who try to run away, only to be caught by fleshy tentacles which have sprouted out of the man's once clawed hand. "oh come on now boys, where's the fun in running?" He mockingly asks to the two men. Izuku can only stare in horror as the two men are torn apart limb by limb, hearing their screams of pain and terror echoing through the alley even after they are long dead. The gutted leader is then picked up by the man as he walks up to Izuku, while he does that he looks to give the man a hug but the body seems to melt into flesh and he absorbed by him. This makes Izuku realise who the man is.

"Y-yyyour A-alex Mercer!" He calls out in shock. Hearing his name, Alex turns towards Izuku.

"That's right boy, wouldn't think someone your age would remember me. You wouldn't even have been born when I struck the news now would you?" He asks as if what he had done to New York wasn't still talked about.

Twenty odd years ago, a virus was spread across the city with more than eighty percent being infected. Most died from the infection, but those who survived were not the same afterwards. They became mindless rabid creates who would kill any not infected by the virus. Some even mutated and became vastly different, some grew taller, with hunched backs claws and their faces warped to be featureless. Some changed to have some sort of scale armour on them, which made it near impossible for heroes that came to assist to do anything.

Then there was Alex Mercer, the Prime as he was called as it was seen that he seemed to be able to control the other infected. He had all the traits of the previously mentioned infected, but he could also absorb people and gain their memories, abilities and even disguise as the person. This let him kill meany of the force that went in to stop the spread of infection called "Black Watch". These men and women were specially trained to contain the virus which was called by many names including the Mercer Virus but its most common name was BlackLight.

Alex Mercer was such a threat that the US government had called in a large number of heros to try and stop the virus. The list included Endeavor and All Might as well as a number of high ranking heros around the world. There was a broadcast which showed Mercer fighting All Might, Endeavor and another hero called Cat's eye who was a high ranking hero in Spain. Mercer was able to kill Cat's eye and beat both All Might and Endeavor.

After the fight, the US government decided to get all heros still alive out. Only All Might and Endeavor wanked out. So, they released they had to stop Alex Mercer, so they issued a order to nuke New York. This shocked many other countries but was seen as the best course of action. So a aircraft carrier with a bomber carrying a payload of a nuke that would distort all of New York was called in. People who were still there were no longer aloud to evacuate, as they could have been infected. When the plane took of however it never made it to New York, it had vanished on its flight in but the nuke went of somewhere in the middle of the ocean.

After this however the infection subsided, and all infected died hours later. However, Alex Mercer's body was never found.

Until today.

Alex looked at Izuku in a curious manner, wait had he… "yeah kid, you just muttered most of that. You missed an important fact though." This made Izuku jump as he knew of his mumbling habit and had tried to stop it, it then sunk in what Alex had just said.

"What did I miss?" Izuku Asked the very notorious villain in front of him. Alex was not surprised by the question however.

So he answered

"I was not the cause of the infection."
