A/N: This is my take on if Izuku Midoriya lost someone that got him in the mists of becoming a hero but became closed up and learned all he can about the mind, the body, and the spirit, but most of all quirks and how it manifests, this will give Izuku Midoriya 11 years to become skilled enough for fighting and the mind but not his mind, more to learn of his fear and hate so it doesn't consume him. Cause He is Vengeance, He is The Knight, He is Batman. (plus keeping the setting and age to everyone)

Chapter 1: The given belief and tragedy struck

This day was the beginning of the end of my childhood, the day of my diagnosis. When I got it I felt that it was just one thing and nothing more but that wouldn't happen for the next couple of years where the despair, hate, and fear where I turned my pain into my vengeance, conquered my hate, and allied my fear as my hero suit and name.

Izuku age 4,

The day has just begun as a black and green-haired boy wakes up on a day that'll put him into a pit of despair. The boy got up and saw his mother ready to leave, hoping that her son would have a great quirk to train the boy, "Izuku, eat and will get going." Inko said.

At the hospital, visiting the quirk doctor.

"Alright I'll be blunt here, there's nothing you have no quirk," the quirk said breaking izuku's heart.

After that, izuku was shocked when the doctor told his mother, "he wanted to be a hero, then he should drop the hero dream he can't without a quirk."

Hero, can't… can't be a hero… can't I can't be a hero. I can be a hero

But when we got home I stayed in my room for the rest of the day, but when my mom walked in.

"Izuku, dinner is ready" Inko went into her son's room to see izuku turning to her as he's pointing at the video of the hero, all might saving people.

"Do you think that I can be a hero like him?" But before his mom could say anything his father walked in after a hard day of work.

"No, you can't be a hero!" Izuku's head dropped down as he heard what his father said, "but that doesn't mean you really can't be a hero, you'll have to be stronger in mind, body, and spirit. So I've already called a couple of places to get started so my son, do you want to be a hero?"

Izuku nodded "yes I want to save people" his father with a great smile "great tomorrow you'll start with every weekday for you to be in gymnastics for three hours with karate on Monday and Thursday, boxing on Tuesday and Friday plus wrestling Wednesday and Saturday, then finishes off with a 4 mile run on Sunday for a rest day to where you will sit after and work on your mind."

(First person)

For the next few weeks, my father took me to find out what I'm lacking in vitamins and minerals plus what foods and meals would be best for me as well as a complete workout plan to be strong but fast as well.

I found out a bit later that my grandfather died and in a letter saying that he believes that I, his grandson, would be a better fit for the company that was called Midoriya Tech. With the will, I received a manor on top of a cliff with a waterfall with ten acres of land, and a butler named Alfred Pennyworth, a British man who learned Japanese.

For the next year, I became a great gymnast, an average boxer, a good wrestler, and a blue belt in karate, plus began to meditate and confront my fears and watched heroes as they save people but as I did I started to question what is a hero. I joined a programming club on Mon and Tues, research Weds and Thu, and a CSI club on Fri in school. But this day is when we finally got the chance to take a look at the manor, for the first time.

When I got there I was excited to find new stuff and locations there but what I didn't expect to be dropped through a hole in a well. I found a new fear of mine, being bats, they flew toward me making me fearful and screaming.

Which alerted my father to where he repelled down to get me, when I told my father that I fear the bats, "the bat down like the bats'' but my father said, "I believe that the bats fear us." "Really?" "Yep we are big and tall, we are scary but the bats are small and can fly, they are scary. It's how you direct the fear you have in you, make them your strength and have it help you and lift you, or have them your weakness and make you crumble." With those words, I started to believe that I could become a hero that could be without fear. But when choose to follow through with it, it was already too late.

Two years after the bat incident, Izuku age 7

(Third person)

Izuku went on to be close with Alfred Pennyworth, as he taught the young man about decoding, manhunting, and burglary. Izuku finished learning boxing, karate, gymnastics, and wrestling. He started learning jiu-jitsu, Judo, and Aikido and continued learning programming, research, and CSI from clubs in school, also went to the library to get books on learning strategies, lib reading, the uberman sleeping pattern and learned speed reading.

Izuku wearing a tux but is waiting for his mother and father because it was supposed to be a surprise for his progress to be a hero, they were wearing formal clothing, Hiashi with a tuxedo matching his son, and Inko wearing a nice black dress hugging all her curves as well as a new pearl necklace, walked down the stairs, "Hey kiddo, you ready to go?" izuku got up, "Yes, come on let's go." Hiashi smiled "Alright, let's go. Alfred, we'll drive, no need to drive us." Alfred nods then walk over to Izuku, "Alright then, but Young master, take this, it's a laminated paper with my phone number on it in case anything happens." Izuku hugs Alfred, "thank you for being a teacher and a friend." Alfred hugs Izuku then pushes him back, " Now, I'm sure that your parents are ready for the fun day right?" Izuku nods, "right!" There the Midoriya family left their manor. Alfred sighed, " I just hope that everything goes fine."

Hiashi and Inko brought their son Inko, to a play from the past Izuku was having a great time until a scene of an actor as bats, to ware Izuku, jerk a bit and then looked at his father, Hiashi looked at his son seeing that he was afraid, "honey, I think we should go." Inko turned to see Izuku afraid, turned to her husband, nodded, and started their track back to their car a building away.

The three started to walk through a shortcut of an alleyway, but then in the darkness, someone walked up to them, the man in the darkness showed the chrome barrel of a revolver, Hiashi saw this and maneuvered himself in front of his family, "THE MONEY And…and the jewels, yeah yeah the jewels." Izuku was scared out of his mind but hoping that a hero would come but was brought back by his father, "Okay, okay here's my wallet." The robber was frantic and when the robber moved to point the barrel of the gun at Inko, Hiashi shifted to keep the barrel of the gun on him which caused the robber to jerk pulling the trigger as the hammer hit the bullet to fly into Hisashi, making him fall to the ground face up, to where Inko screamed making the robber get in a rush grabbing the Pearl's with a squeeze of both hands pulling the trigger shooting Inko as he pulled the hand grabbing the Pearl's yanking the necklace breaking them, keeping two for himself and leaving the rest bouncing on the ground aching as he heard police sirens and decided it was a good time to leave

When the robber left Hisashi used the last bits of strength he had, "Izuku," hearing his name he looked to his father seeing a trail of blood coming from his father's mouth, "I… Zu… Ku, be th…the, hero me and y…your m…mother be…believe y…you can b…be, Don't be afraid." Leaving his last breath as izuku ran to the side of a dumpster and got his knees to tuck into himself.

It took 8 minutes for the police to appear and took 5 more minutes for detective Tsukauchi to arrive what he saw made his heart ache to see the two dead bodies and an alone child, but what made him mad was the apathetic feeling that his fellow police officers were giving to the young child, so he walked carefully to the boy and took a knee in front of the boy taking off his trenchcoat and putting on the suffering boy, "Hey kid let's get out of here." But heard, "izuku," tsukauchi was confused and asked, "huh? What was that?" Izuku looked up at the man with a small smile, "My name is Izuku Midoriya, sir." The detective gave the boy a little smile, "My name is Detective Naomasa Tsukauchi, let's take you to a place that's a lot warmer and not so cold as here?" Izuku solemnly nods his head,

Detective Tsukauchi drove Izuku to Mutsutafu's Police Department, Detectives Tsukauchi brought some hot chocolate to izuku to warm up and to give izuku, "Tsukauchi!" Tsukauchi jerked his head towards the voice and saw Tsuragamae Kenji the chief of the Police of Mutsutafu,

The Detective walked out of his office where Izuku was left, to go into the Tsuragamae Kenji's office, "So, 'ruff' What's with the kid?" The detective went to take a seat to start explaining, "Well, sir That kid's name is Midoriya Izuku, he's quirkless and he saw the robbery and murder of his parents. He must be in shock at what had just happened so I'm letting him have time to let it out to where he can talk for a bit." Tsuragamae Kenji looked at his detective and nodded, " 'ruff' Do what you can to help the kid, and If you can get in contact with his guardians then find what you can with the crime that happened."

Tsukauchi nods as he left when he enters his office seeing the boy he left in to see him on the phone, "so mind if I get the phone to talk to your guardian?" Izuku handed the phone to the detective, "Hello Detective Tsukauchi here, may I get the name I'm talking to?" "The name's Alfred Pennyworth, young midoriya butler, I'll be on my way to the department to speak in person."

Some time passed, and Alfred Pennyworth arrived and went to Izuku, "Alfred!" Izuku ran into the arms of Alfred, "Izuku, I'm so happy that you're okay, when I heard what happened to you I came as fast as I could." Detective Tsukauchi coughed, "Mr. Pennyworth, I need Izuku to tell me what happened." Alfred looks at Izuku who nodded. It took 10-15 minutes to tell what happened, answer what questions were asked, and give more details needed. "Thank you Izuku, you can go home and I'm sorry for your loss." Izuku smiled and mouthed 'Thank You' and left the department with Alfred. April 25th is the date that will hunt izuku midoriya's life for the foreseeable future.

2 weeks have passed and it's the funeral for Hiashi and Inko Midoriya the parents of Izuku Midoriya, The Bakugo family friends of his mother Inko, the standing CEO of Midoriya tech plus a good friend of Hiashi, Lucius Fox, and Detective Tsukauchi had came to pay their respect. "I'm going to tell you, that I'm going to tell you, if you are trying to be a hero after this, then try to not make this the reason. You have the motivation to be a great hero just please don't allow this piece of Darkness to consume you." Izuku nods, "thank you, sir, I'll keep it in mind."

After that Detective Tsukauchi left the Midoriya Manor, then Mitsuki Bakugo walked close to Izuku "Izu-Kun, I want you to know Masaru and I are available to talk to, plus to help you." Izuku nods and hugs Mitsuki, "Thanks Auntie Mitsuki, I'll do it if I need anything." Masaru went to say how good my parents were and left,

next was Lucius Fox, he walked up. Izuku and he knelt, "Hey Izuku, your Father Hiashi when we talked he'd say how good your training is coming along, and it would be a matter of time till I would meet you to get your first suit fitted, but this is not a good time, well if you need something in help with the hero gig, I've already given my number to Alfred if you need it." Lucius got up gave the nod to Alfred and left,

all this time Izuku hadn't shed a tear, but when he got home and then entered his parent's bedroom, he just got into bed and wept himself into sleep, while this was happening Alfred was standing aside hearing the whales of misery coming from the boy.

It has taken 2 months for Izuku Midoriya to get back into a realm of normalcy, but the Innocence that came from the boy has been ripped away from him forever.

He has restarted his training to become a hero with much more fervor and viciousness to get it done as quickly as possible, with his desire to learn as many things that he could Magic, science, math, history, geography, fear, love, hate, criminal mindset, and anything else that relates to him coming to a hero that wouldn't allow what happened to him happened to anyone else.

But the one thing that kept with izuku midoriya was his analysis for the future when it comes to quirks. He decided to create contingency plans for if he ever encounters any of the quirks that a villain or hero has, and will adjust them for when he learns something new.

At this moment, the date is July 3rd, and Izuku is on his way to Midoriya Tech. Izuku walks up to the front desk "is Lucius Fox in today?" The front desk clerk gave 'the kid I don't give a shit about my job' look, "why should I tell a kid that?" As the kid looked up to see the sign that read 'Midoriya Tech' the kid pointed, "My last name is behind you, and the name is Izuku." A man was walking to the front desk seeing the flattered security guard's face, "Well, Martin how are things?" Martin the security guard straighten up hearing the voice of his boss he calmly spoke, " This child is trying to convince me that he is a member of the Midoriya family, but the only midoriya that I know of that I have strict orders from the man before he died to allow was his grandson Izuku Midoriya to have unlimited access and I deeply believe that this boy is not him." Lucius Fox just chuckled a little bit hearing what the security guard just said as he went on and responded with, " Martin, the skin is izuku midoriya he has a right to be here and I wonder why he is here, Izuku come with me." Izuku walked behind Lucius Fox to his office,

In the CEO's office, Lucius Fox brought the 7-year-old to his office to get to talking after all one of the last words that Lucius Fox heard from his good friend Hisashi, was to help izuku in any way possible to become a good or even a great Hero. "So how's your journey to becoming a hero?"

Izuku went on to put off his backpack to take his hero analysis for the future 1 - 9, and a notebook filled with support items for him to use. "This is everything I've analyzed about quirks and heroes and I would like for you to create a material that would protect me from most of the quirks that I've analyzed I don't want you to take a look at most of the quirks that have been used for villains as well as for heroics. Plus I would like to make a suit that would protect me from impacts that wouldn't be less than a thousand pounds per damage but be mild damage when it's above a thousand pounds of damage, if you can build such a suit then the next 7 years then I will like for you to do that for me please off the books off the Record, and for the next 7 years build me a top of the line computer to analyze crime scenes visions. That would see things that I wouldn't see with my eyes personally, have the computer be able to decode almost everything with the algorithms that are needed, and any book of coding, that I will read when needed plus I would like for you to hire people to make a place underneath my house. That's what I want, is there a possibility for all of that to be successful within the next 7 years." After hearing all this Lucius Fox knotted everything that Izuku said but he went on and added, " Do you want a training area, a medic area, a tech area simulation area, and a storage area? What do you want to have me do?"

Lucius Fox proceeds to stare at izuku midoriya watching the boy thinking about almost everything, every single possibility and every type of thing always thinking about the next problem. That is when he thought about it, and the boy said, " placements to present my suit set and I think that I want to make a fear that I had into my symbol of sorts the fear of bats small creatures fearing of us but I'm going to use it change it conform it into my own it'll take some time and I have time." Hearing this Lucius Fox smiled and said, "I'll I'll do that but I'll make a little basement the entrance will be right there an elevator behind the bookshelf will go all the way to the bottom that is where I'm going to work on your support gear no one else will have yours so what's going to happen in the next 7 years?" Izuku took some seconds to before speaking, " first I'm going to finish learning Aikido Judo and jiu-jitsu, it'll take around a year year and a half at the most to finish it and then I'm going to go on and start to travel and then I will come back before the UA exam opens up enough time to practice with every suit and gadgets that you make for me and enough time for you to make new Jack gadgets that I find out in the wild that's it for me." Lucius Fox nods, " Before you go I want you to take a tracker on you to make sure you're safe." Izuku nods understandingly before saying thank you and leaves home.

Is a good Midori is now 8 years old a year has gone by since the death of his parents and he has learned Aikido Judo and jujitsu right now he is at the airport getting ready to leave Mutsutafu Japan for a journey of learning understanding and mastery of who he is and how he is for the next 7 years he will learn what it means to be prepared to be one with his body to have a strong mind and a strong soul as well from this journey he will learn the art of Escape paragliding, skydiving, meditation, mental blocks, how to open them how to close them, perfect diet to make sure that he's in perfect condition, the best workout plan for him and stunt driving.

The end
