Izuku woke up the next morning and want right for his computer. He opened the computer and was greeted by his old All Might background.

"Ya before I do anything I'm changing this shit." Said Izuku

Izuku change his background to his favorite anime growing up, Bleach.

"Much better. Now back to what I was doing." Said Izuku as he types something into the search engine. Quirkless heroes. As Izuku hit search the only thing that came up were interviews with heroes, where the question was asked if someone with out a quirk could be a hero. Every hero answered the same. No they couldn't. As Izuku reached page 5 of the google search he was about to give up when he saw something that caught his eyes.

Vigilantes, Heroes or villains.

"Vigilante. That could work. I'd still be helping people and some people would still see me as a hero. Sure some might see me as a villian and the cops and heroes would try to arrest me but fuck it." Said Izuku as he turned off his computer.

Izuku got up from his desk. He walked over to his dresser and looked at a picture. The picture was of Izuku and his mom.

"Hey mom. I have something to tell you. Instead of becoming a hero I'll be a vigilante. Wait now before you freak out just hear me out. I have the power to become a hero but it's not a quirk and due to that no hero school will except me." Said Izuku "However I know I can help people in a way heroes can't. I can save people prevent what happen to you from happening to others." There was silents for a few seconds. "Thanks mom I knew you'd understand and yes I promise to be safe. Love you mom" Said Izuku with a smile.

(Two week time skip)

Izuku had been preparing for two weeks for his first day as a vigilante. First he needed a name for his power he somehow obtained. Izuku thought long and hard about it and settled on calling it Ultra Instincts, since his body would dodge attacks even if he couldn't see them. After that Izuku made himself a costume. It was very simple. Since his body would dodge attacks he didn't put much protection on it. The only thing he put on for a reason was a blindfold. Izuku could see through the blindfold. It would also negate quirks that needed direct eye contact to work. (Custom pic Down below)

Izuku had also been going to school like normal but it was different Bakugou got excepted into U.A so Izuku hadn't seen him and school was actually peaceful with out the class douche.

"I still can't believe U.A let a piece of shit like Bakugou in. Well just goes to show you how fair quirks will get you in life, but I'm gonna turn that on its head. I'll be someone who shows the world it's not the quirk that makes the hero it's their actions." Izuku said. "Mom, I'm doing this for you."

Izuku began to put on his costume. "When I'm in this custom Izuku Midorya is no more. For all villains that cross my pass you will know me as Instincts." Izuku said as he tied his blindfold around his face.

Izuku left his apartment and began to jump from rooftop to rooftop. As the day want on Izuku stopped three petty thefts, two muggings, and one attempt of murder. It was pretty easy
With the thefts Izuku didn't even need ultra instincts, the two muggings were taken care of in less than a minute, and Izuku knocked out the guy who attempted to murder someone in one hit.

"Wow so far the crime today is pretty boring. Well not to say the crime is boring but the criminals are boring. I was hoping for more of a fight." Izuku said as he continued to jump on the rooftops. Izuku checked his watch. He left at 9am and now it's 5pm. Izuku was about to head home but he heard something that he needed to act on.

"Wow we scored some hot ones today."

"We sure did. The hero types are so easy to fool."

Izuku looked behind the house he was standing on and saw 4 men and three young girl on the ground. One girl has brown hair and brown eyes. Another girl looked kinda like a frog, she had green hair and black eyes. The final girl had a black spiky ponytail and black eyes.

"Ribbit. I can't move my body." Said the frog girl.

"I can't either." Said the girl with brown hair

"You bastards. What did you do to use?" Asked the black haired ponytail girl

"Simple I used my quirk." Said a man with spiky yellow hair, red eyes, and a lip ring. "My quirk lets me paralyze anyone I've made direct eye contact with for 45 minutes and trust me 45 minutes is all the time we need."

"Come on we're wasting time. Lets get on with the fun." Said a fat man with barely any hair and blue eyes.

"Not on my watch you sick fucks." Said Izuku as he jumped off the roof in the direction of the fat man

who was reaching for the ponytail girl's breast. Izuku landed on the man sending him into the ground and creating a cloud of dust around himself. Izuku's Ultra Instincts kicked in and then he picked the man up by the head before smashing his face back into the ground knocking him out cold.

"What the hell was that?" Asked a man with green skin

"Scum like you make me sick. Tricking young girl just so you can have your way with them, oh oh oh I'm enjoy kicking your asses." Izuku said as he stepped out of the smoke cloud, cracking his knuckles at the same time.

"Who the hell are you? Wait it doesn't matter you're gonna die soon anyway. Kill him boy." Said the man with the lip ring

"You got it boss." Said the green skin man and a man with holes in the palms of his hands.

(Izuku's point of view)

The two scumbags charged me. The man who has green skin turned his arm into the clawed arm of a lizard. He attempted to slash my chest but my body moved out of the way. I then kicked him in the face forcing him to take a few steps. My arm then shot up and a grabbed a chain before it could hit me.

"So you'll catch attacks along with blocking them. Nice." I say to myself

I pull the chain towards me and it's revealed that the man with the holes in his palms can shoot chains from them. As he gets closer I punch him square in the face, sending the bastard flying into a wall. My body moves once again back flipping over the lizard man who was trying to stab me with his claws.

I then unleash a flurry of kicks into his back before kicking him over the head, sending him face first into the ground. As I land my arms catch two chains.

"Really. You're trying this again?" I asked as I pull the chain man close to me. When he was close enough I headbutted this motherfucker into the ground. I then use the chain I was still holding the swing him over me and plant him firmly into the ground.

All three men were knocked out. I then looked toward the boss of this group. He took a few steps back. Since my eyes were covered his quirk was useless

"Wait man. If you let me and my boys go, you can have those girls all to yourself." He said in a panic

"First you attempt to rape three young girls, then instead of running you attempt to kill me, and now you have the balls to try and bargain with me!" I shout as I launch myself toward the lip ring man. In less than a second I'm right in front of man. His face is full of fear. I pull back my fist and unleash the mother of all punches square into this man's ugly face. My punch send the man flying through a brick wall and knocks him out.

"Ribbit. I can move my body again." Said the frog girl

"Me two, but how. Its been no where near 45 minutes." Says the girl with brown hair

"His quirk must loss its effect if the user is rendered unconscious." Answered the ponytail girl.

Knowing that the three girl could move again I begin to walk away, since I know they'll call the cops.

"Wait!" Shouted the brown hair girl

I turn around and see all the girls starring at me.

"Thank you for saving us." Said the brown hair girl

"Ribbit. Thank you." Said the frog girl

"You have my thanks as well." Said the ponytail girl.

"No problem." I replied

I was about to start walking again but the ponytail girl asks me another question.

"Who are you? Are you a hero because if so I haven't seen you before."

"You can call me Instincts and it's up for you to decide what I am." I say

"Ribbit. What do you mean by that?" Asks the frog girl

"As time goes on people will call me many things. A hero, a villain with morals, or just villain. However I prefer the term vigilante." I say this and all the girls have a shocked expression on their faces. "Make sure you call the cops so these scum bags can get arrested. Also get home safe." I say as I jump back onto the rooftops and begin walking home.

(With the girls. Third person)

The girls called the cops and had the men arrested. As the cops questioned the girls they explained everything including the part about the young boy who saved them.

The cops said that they were lucky that the boy showed up but if they saw him again they should report him to the cops.

"Wait, why should we report him? He saved use." Asked Uraraka

"You said he called himself a vigilante. While vigilante do some good they're still breaking the law by using their quirk, doing hero work with out a license, and they break the law multiple times. While I can't make you report him if you're heroes in training you should report him even though he saved your life." Said the cop

After a long talk the cop let the girls go. While they walked home they all had one thought on their mind.

"I don't care what they say. If I see Instincts again I'm not turning him in."
