Chapter 1:enemy of my enemy

Izuku Midoriya never wanted anything more than to be a hero when he was a then he was diagnosed as quirkless and he lost everything. His friends left him behind and his father and mother left him. But this isn't his origin story, This is the story of how he became the most feared hero hunter.

"Man, can't believe it's already the five year anniversary since we became full-fledged heroes!" Denki Kaminari ,aka chargebolt, was in the middle of his patrol around hosu city with his fellow class 1-A student Mina Ashido.

Mina smiled as she waved to a passing civilian, "I know right! I'm so excited for the party Yaomomo is throwing for us later!" She said with a squeal,excited to see her classmates she hasn't seen lately because of hero work.

Denki threw one of his fists up and cheered before bumping into someone. "OH, my bad man, I didn't see you there, I'm sorry" He said while holding a hand out for the knocked over person up.

Mina looked at the knocked over person and looked the man over and saw him in just a pair of work out pants and a tight black shirt.

The man took Kaminari's hand and stood up then dusted himself off. "It's not that big of a deal, it was just an accident" He said and gave a smile with closed eyes.

Kaminari gulped a bit at the grip on his hand but smiled back. "Thanks for understanding, i just got too excited about tonight" He said before trying to pull his hand back but saw the man still had a grip on it. "Hey, you mind letting go?" He asked, looking at Mina for help.

Mina watched the man carefully, something in her mind telling her this man wasn't as he seemed.

The man let his smile leave his face slowly,then gave a hard squeeze to Kaminari's hand quickly then let it go. "I'm sorry about that, I'm just a big fan of heroes and i know how famous you guys are from just your first year of UA" The man said with a glint in his eyes.

Mina and Kaminari shared a quick look before Mina nodded for them to continue their patrol.

Kaminari looked back at the man and put a big smile on his face. "Ah well thanks for the support man but we have to get back to patrolling the streets and do hero things. So hopefully we see you around and stay out of trouble" He said with a chuckle at the end before he heard a second chuckle.

The man started chuckling before letting out a loud laugh. "Oh man, that was needed. But I'll let y'all go on about your day but I do hope for your sake, we never see each other again" The man said, before walking past them ,bumping shoulders with Kaminari, and leaving their eyesight.

Kaminari froze, feeling the pain the man could bring him and let out a breath he didn't know he was holding. He looked at Mina and saw her as pale as she could get and eyes wide with fear. "W-who was that man and why did i feel like he could kill us without trying?" He asked, trying to stop shaking.

Mina let out a shudder and pulled out her phone. "I don't know who that was but we gotta report this to edgeshot and everyone we can to look out for him. Because that feeling he made us feel, It reminds me how Iida said he felt fighting stain" She said, pulling up the class 1-A group chat and sending a message.

Shota Aizawa was far from the hero he once used to he lost a leg only to get it back because of his adoptive daughter Eri, Then he starts losing time on how long he can use his quirk. And now he was having to deal with a mess he didn't wanna be near because of Shinso.

Aizawa walked around the crime scene and tried to ignore the smell of blood and bile. He sighed and scanned the room before he heard a pair of feet hit the ground behind him,causing him to turn already in a fighting stance, But saw it was his student Shinso Hiotoshi.

"What did i tell you about sneaking up on me?" He said with a glare on his face.

Shinso smirked before walking up to Aizawa. "If i was able to sneak up on you then i guess your hearing really is leaving you" He said with a bored tone before scanning the room. "ANy idea yet who could've done this to so many heroes?" He asked looking over at Aizawa who just shook his head.

Aizawa rubbed his stubble and yawned. "Not really,I have an idea but I can't be positive until another hero agency is struck, which can't be too far away if who I think it is is in the area" He said before turning around and leaving the scene causing Shinso to walk after him.

Shinso knew his mentor wasn't one to talk about much except cats but he still knew when his teacher was hiding something. "You know, keeping every secret you have doesn't work when we are trying to find a serial killer. Who, might i add was strong enough to beat and kill many of the heroes from that agency" He said before feeling his phone buzz in his suit pocket.

Aizawa looked at his phone after feeling his phone buzz too and saw it was his former problem class's group chat. He let a small smile out underneath his capture scarf and read the message from Ashido.

Shinso sighed as he read the chat. "Well maybe this dude Mina and Kaminari ran into could be a then again how would they get from mustafu to hosu so fast?" He questioned silently before hearing Aizawa let out a sigh and mumble. "What did you say?"

Aizawa looked up at Shinso and thought for a minute before motioning him to follow him. "There is a legend in the underground I haven't told you about yet" He said while looking around to see if anyone was watching them before he took a seat on a nearby bench.

Shinso sat next to Aizawa and started looking around feeling like someone was watching but could never see who it was.

Aizawa coughed before he started talking again. "The legend goes that there is a man. They say this man is one of the scariest and most skilled bounty hunters there has ever been. He is known to go after heroes and villains alike" He said trying to hide the shiver running down his back.

Shinso's eyes were wider than usual and gulped. "Why is he known to be the strongest?" He asked not wanting to show he had fear in him.

Aizawa looked at Shinso before deciding to continue. "He is feared because he has been known to have beaten stain in a fight bare handed at only 18 years old. But apparently he is also feared because he has done all his killings and beatings while being quirkless".He said, causing Shinso's eyes to fly open.

"A quirkless man is the most feared man in the underground?" He asked louder than he meant and looked around to see who heard before he set himself back into his tired form. He leaned closer to Aizawa, "How is it even possible that someone with no quirk has been able to beat the hero killer and has the boogeyman of the underground scared?" He asked while gripping his pant legs.

Aizawa let out a chuckle and rubbed his chin. "Because I was there when I saw him beat down Stain" He said, making Shinso look at him more. "That's not all, I know he is quirkless because I used my quirk on him to see if it would make him lose the worm he had wrapped around his body because I thought that was his quirk. But it didn't go away. All it did was growl and alert him that I was there. Then he looked at me and all I felt was the intense form of his Killer intent directed at me and I knew I didn't stand much of a chance against him" He said while rubbing his sweaty palms on his pant legs.

Shinso shook as he listened to his teacher and mentor explain how even he was scared of this so-called monster of a man. "What did he do after he saw you?" He mumbled out trying to keep his breathing even.

"He just stared at me then he turned back to stain and spoke to him. I didn't hear what he said but once he finished he walked away and left stain laying there" Aizawa said before e stood up and looked like he didn't have any fear in him again. "If it is him who has started tearing down hero agencies again then I do know that you should try and avoid fighting him alone. I believe not even All Might in his prime would have taken The hero hunter down by himself" He said before he walked away leaving Shinso there by himself to think about their talk.

Shinso sat there for a few minutes before he felt his phone start ringing and saw it was Reiko calling him, bringing a small smile to his face. He answered and brought the phone to his ear, "If it isn't my favorite ghost" He said softly and heard a small giggle on the other end. "How was work today?" He asked her as he stood up and started walking back to his apartment prepared to spend his night searching for all clues on the so-called Hero hunter.
