Chapter 1: The Beginning of the Bat

It happened in this night, the night that changes everything. No hero was around when it happened, either they're signing autographs, doing interviews, or stopping villains and giant monsters. But once they get there, it'll be too late.

Izuku Midoriya, age 5, was just sleeping peacefully in his room after watching another All Might video. He had a bad day since the morning at the doctor's office, when it's discovered that he was Quirkless. It became worse when Bakugo learns this and starts bullying him about how he can never be a hero without a Quirk. It hurt him so much.

His mother, Inko, has tendered her son about his bad day. Ever since her husband passed, she has kept raising her only son, her only family in the world, to make sure he's taken care of. Izuku doesn't know much about his father, but as Inko put it, he was a "stoic". A well famous doctor that helps treat patients, as well as always help others before his passing.

But now, things will change. Izuku's day will get worse.

As the young Izuku was sound asleep, his couldn't sleep due to some yelling outside of his room. Curious, he wakes up to rub his eyes, as he steps down as when he's fully awake, he froze when he heard yelling.

"I said give me all you got, woman!" shout a threatening tone.

"P-Please, my son's asleep." His mom cries out.

"Do I look like I give a fuck?!" Izuku peaked through the door, his mom is pinned to the wall in tears, by gunpoint by a man in black, wearing a black toboggan and pale skin with black spots from his ear to his scarred eye. "Either you give me the money, or I have to beat you down with it!"

Inko was scared, scared of her own life as well as her sons' life. She notices her son peak through the door of his room as she nodded her head 'no' silently.

The man notices her gesture, as he turns his head and the gun away to spot Izuku. The young boy panics, as the man groans "Shit!" he cursed.

Inko's own body jumpstarted, once the man let his eyes off of her for one second, she rushes in to the man's gun as she shouts "Izuku, run!"

BANG!

But in mere seconds, Inko felt a hot pain into a vital part of her chest. She felt cold when she falls down to the floor, watching her sons' shocked face. 'Izuku, I'm sorry.' She thought.

"Dammit!" the gunman cursed, seeing Izuku frozen in fear as he rushes out of the window. Crashing through to get away once the police sirens are heard.

"MOM!" Izuku shouts as he rushes towards his mother, lying on the floor bleeding out. "Mom! Please, get up! Please!" he keeps moving her, getting blood stains from his hands.

"I-Izuku." Inko's raspy voice was heard, caressing her son's cheek "Don't worry, you're safe…you're safe…" tears sprang from her eyes as her hand fell from his cheek, as she starts to feel limp.

No sooner did the young Izuku saw his mom dying, the police barge into his home. They were too late, Inko Midoriya is dead.

/

Everything fast forward, as Izuku's now on the chair of the police office. He didn't move an inch as the police were forced to get him to stand up. He was covered in a blanket, shivering in fear.

"Poor kid." Spoke one officer "Losing his mother like that."

"I can't believe that criminal got away!" spoke another officer. "It makes me so mad that it had to happen to a poor kid!"

"Not to mention, Quirkless." Spoke a female officer. "I hate to see kids like him having to go to a foster home."

"Would you be quiet!" the first officer hushed at her "He could hear you!"

Izuku didn't care what the officers says about him or where he's going. All he cares about was that man, the man who killed his mom. But then something next happened.

"Midoriya Izuku." The young boy raises his head up. He was shocked, that standing before him was All Might, the number one hero of all time. He was kneeling down, as his hand was on Izuku's shoulder, as the boy saw tears from the hero. "I am so sorry that I didn't save your mother in time!" he said apologetically. "I was so busy dealing with a villain, that I didn't come to realize that a murder happened! I arrived too late, and it cost your dear mother, Inko, to lose her life!"

Izuku took his words at ease, All Might have felt genially guilty for what happened. The young, Quirkless boy didn't hold it out to him, he was trying to do his job. Why didn't Izuku say anything to the hero right now? Did he blame All Might and the other heroes to not do anything? Or did he felt ashamed that without a Quirk, Izuku didn't do anything to stop him mom's death.

Knowing that Izuku didn't respond, All Might sigh. 'I guess he blames me for not stopping earlier.' He thought as he heard one officer spoke.

"All Might! There's a situation down at Fourth Street! A villain with a rainbow Quirk has been stealing paintings!" the officer spoke.

"I'm on my way!" All Might have declared, as he turns to Izuku who has his head hang down. 'I hope things will get better for you, my boy.' He thought as he rushes into action.

/

Fast forward to the funeral, where the young Izuku stood to see the preacher praying for his mother. Izuku stood by her grave, as many people that knew Inko came. Neighbors, friends, acquaintances, and co-workers. Soon, people went by and go, but Izuku only stood.

"M-Mom." Izuku sniffs, as he wipes his tears as he sees her grave. "I…I promise to be a hero…and take that man who shot you to justice!" he grits his teeth; his eyes now shift as new emotions rises.

Anger, revenge, and on edge, that's what he's feeling. Unknown to him, Bakugo in his funeral clothes was up and behind. He didn't show his cocky smile today, but this time it's sincere.

"Oi, Deku." Bakugo calls out to him. "My mom said that you can live with us." He heard nothing but silence from Izuku. Bakugo has never dealt with someone who lost a family member, he may be a jerk but he's not cold hearted. "Hey! I'm speaking to you! I don't do this feel better shit, so why don't you-"

"Shut up!" Izuku turn his head, as tears still runs from his eyes, his once innocent eyes turn to a glare. A glare that his pupils turned dark red, as it gives an effect towards Bakugo once he saw his glare. It caused the spiky blond boy to fall back on his butt.

'What the fuck was that?!' Bakugo thought in shock, feeling the intensity of the glare coming from the Quirkless boy. Or is he Quirkless anymore?

Mustufaru, 9 years later.

In the city's shopping area, a girl with black pineapple hair, fair skin, black eyes, and wears a black, sailor schoolgirl outfit. Despite being in Middle School, Momo Yaoyorozu is quite heavily beautiful and has a scholarship to UA once she graduates from her middle school. But after she has gotten out of the bookstore, she ends up being cornered by a gang of thugs.

"P-Please, back off!" Momo begs as she is pinned to the wall.

"Oh, come on, honey, we're just going to show you a good time." Spoke the thug with antennas. He saw Momo looks around, and tries to escape but is grab by the thug and is push to the floor. "Hold her!" he told his goons. The group of thugs then pins Momo's arms and legs down, as the leader grabs her school shirt off, showing her red bra covering her cleavage. "Oh man, she's stacked!"

"Can we have a turn after you, boss?" ask the dogman.

"You all will get turns once she doesn't scream! And there's no hero on sight to stop us!" declared the villain as he covers Momo's mouth, once he begins to pull down her skirt, ignoring her tears.

'Someone, help me!' Momo thought as she closes her eyes, once she meets the inevitable.

WHACK!

The leader was smacked away from Momo, as well as his three gang of rapists with one swipe. Momo opens her eyes after feeling the gang off of her. She was shocked when she saw someone standing in front of her holding a bo staff.

"What the fuck hit us?!" Asked the leader.

"Me." spoke a voice that sounds like glass scratching on sandpaper. It sends shivers down in Momo's spine when she saw the figure. He looks to be a height taller than her, wearing all black. A pitch-black cowl with large pointy ears, resembles a bat. White lenses to cover his eyes, and only the part of his mouth and chin are exposed. His cowl is connected to a tattered cape, with a gray, kevlar bodysuit with a symbol that resembles a bat. A yellow utility belt with the same symbol, and wore black gloves and boots with spikes.

"Who the fuck are you?" demand a snake-faced gang member.

"Someone who will teach you what happens to scumbags like you!" spoke the Bat. The gang charges at him, ready to beat and kill him for whacking at them. But the caped man was prepared for them, each of them.

The snake-faced man charged first, slither towards his opponent in attempt to wrap him up. However, the dark hero pulls out a capsule and throws it at him. It exploded into white smoke at the snake-faced man who felt drowsy.

"I feel…cold." He said as he faints on the floor.

The dog man pounces at the dark hero, follow by his comrade, a tigerman. The dark hero ducks down making the two collide, as he spread smoke screen surrounding them, including the leader.

The three all cough at the smoke. They look around as the leader shouts "Where the hell are you?!"

"AHH!" the tigerman screams as he's being taken away through the smoke.

"Sabers!" the dog man cried out, as he felt someone grabbed him through the smoke "OOOWWWW!" he howled.

The leader looks around, seeing his gang have went up and disappeared. "Y-You think you can scare me?!" he asks as he saw his snake goon gone as well. "Sabers? Pound? Kobra!" he shouts for them, until he heard painful cries of his goons.

"AAAAAAHHH!" they screamed in unison. The leader looks around in shock as he backs away, then he saw the smoke fading away. He saw Momo hiding behind the trash can. This gave him an idea as he rushes towards her and grabs her ankle with his out stretched hand, pulling her out.

"No! Stop!" she cries out, as she saw him pull out a knife.

"You better come out before I kill her!" he threatens, unknown to him that the dark hero was behind him, towering over him with his hands in a knife position, did two chops on each sides of his head. "GAH!" he yelps, dropping the knife down the ground, as he falls down to unconsciousness.

Momo was shocked to see her savior took out those crooks that tries to rape her. What's even more shocking is when he ties the leader up along with his gang, she saw him pick out something, like a brander with a bat-symbol. All she can hear was the screams from the leader after he insert it to his neck before hanging them up from the fire escape.

She then saw him confronting her. She didn't know what to think, he may have saved her but why does he look so damn scary. She wanted to run, but it was then he spoke to her, calmly.

"Are you okay, Miss?" he asked her.

He must be a hero, but not someone who she recognizes. "Y-Yes, I am." Suddenly, police sirens are heard, making Momo turn around to see the squad cars coming, as well as some Pro Heroes. "Looks like the cops coming. Maybe you can join and tell them-." Once she turns around, the bat hero was long gone.

/

"Our top story tonight, a life was saved by just not any Pro Hero, but it appears to be a mysterious vigilante. From what the Pro Hero Strong Arms has to say." Spoke the anchorwoman who moves her microphone to the buff hero, Strong Arms.

"When I got called in to an emergency, a tip about a gang rape that was about to occur." Strong Arm states "However once I got there, the girl was laying on the floor while her assaulters were hanging from the fire escape."

"The girl, Yaoyorozu Momo, and 3rd year in St. Kamui Middle, was safely unharmed after her assaulters were apprehended. Can you tell us what happened, Momo-san?" the reporter asks her.

Momo, who was covered in a police blanket, answers "I was just walking to the bus stop, until my attackers came towards me. They use force to have their way with me, but then he came."

"He?" the reporter asked.

"I don't know his name, but he had a bat-like cowl, and was very skilled in beating up my attackers."

"Were you scared?"

Momo was silent for a second, as she answered "I was at first, but I am grateful for saving me from such a horrible experience. The man in the bat cowl, if you're watching this, thank you!" she said with a smile on her face.

The news story is seen from the jumbo screen on a building for all of Tokyo to see. Standing on a building in the shadows, was the caped hero that saved Momo.

He tapped to his ear piece, as he spoke "Oracle, report."

"There's a bank robbery plus a hostage situation at the Kabashi District. About 5 miles from your end. No Pro heroes near on sight."

"On it." He responds, as he brings out a grappling hook gun, shoot it, and flies off from the rooftop.

/

At the bank, many civilians in there are down on their knees, hands up, as many robbers were escorting money from the bank.

"Ah, the sweet sight of a robbery at night!" spoke the leader of the gang of robbers. He is a bald man with red eyes, pale skin, and wears a black sweater and pants with combat boots. The most bizarre about him are the tally marks on his face and hands. "Now, who do I kill tonight?" he asks as he sees the bank teller quivering in fear. "How about you, Mr. Bank Teller? Would you like to be Mr. Zsasz's 200th kill to add?" he asks the bank teller.

"P-Please, I got a wife and kids!" he responds, making Mr. Zsasz laughs at him.

"I did too, they were my first kills." Zsasz replied as he looks at the bank teller's eyes, making him froze.

Zsasz's Quirk: Petrification Stare – The ability to stare in the eyes of others, causing their body to be frozen in motion. The nervous systems shut down as the person frozen in state, the person's body becomes stand still like a statue.

"Can't move, can't speak, just like a statue." Zsasz states with glee, as he brings out his switchblade "Now, should I do the old stabby-stab in the stomach? Throat? Or do I chop your fingers up?"

"The only thing you'll be doing is a life sentence in prison." Spoke the dark hero appears behind him.

"Fucking lord!" Zsasz shouts in shock after he turns around. "What are you scaring me like that?! Don't tell me you're one of those Pro Heroes?!" he then looks around, seeing none of his men around "The hell are my men?" he saw the dark clad man pointing up, as Zsasz looks to see his men tied up in wires. Most of them knocked out. "How did you do that without me hearing?! And in under one minute!"

"Trade secret." The bat-themed hero replied as he dashes towards Zsasz to kick him away from the bank teller. This cause the bank teller to move again after Zsasz broke eye contact. The scared criminal sneers at the dark knight.

"You know, I thought I was gonna kill a hero for my 200th kill, but I think you'll be my 200th special!" Zsasz states as he brings out his switch blade, charging towards the caped figure who dodges his attack, then grab his wrist making him drop the knife, and elbowed his arm down to his forearm. Zsasz screams in pain, before he gets kneed in the gut, making him cough out air.

"Sloppy." He said as he threw Zsasz down to the floor. Zsasz rubs his arm. Zsasz charges again with his good arm to aim at his face. The Bat simply grabs his fist, and saw that Zsasz brings out another switch blade to stab him in the stomach. Fortunately, he turns Zsasz around and grabs his knife hand, making him drop it and then handcuffs both his wrists from his back.

"I'll show you sloppy!" Zsasz turns his head around, getting into eye contact with the bat-themed hero. However, before he can activate his Quirk, the bat hero's eyes intensify, a glare he formed to make Zsasz felt actual fear. 'What's going on!?' he thought 'The moment I stare at his eyes, I'm paralyzed in fear!' he thought as he felt actually afraid of the bat hero.

Zsasz was shocked that he was bested, as he felt being lifted and thrown out of the window. He then trembles around the street, surrounded by the police.

"Freeze!" an officer declares. The cops didn't notice it, but the dark hero was long gone.

/

"Bank robbery was prevented this night…"

"…Another bat man report…"

"He just came out of nowhere and wired these guys up…"

"The police are still questioning about this bat-themed hero. Who is this…Batman?"

The news reports were paused by the anthropomorphic mouse, Nezu, as he's with the Heroes Association about the matter subject on "The Batman" as the media calls him.

"This is very problematic indeed." Nezu spoke as he turns around facing his fellow Pro Heroes. "Vigilante cases are nothing new, but it appears that this one is the most brutal of all." He uses the screen to bring up a picture of the Batman for the Pros to see.

"Yeesh, he's supposed to be some kind of a bat-themed with the pointy ears and cape! What kind of theme is he if he's not an actual bat?!" Present Mic comments.

"I think he looks hot in that outfit." Midnight replied with a shrug.

"But the way he fights them, does he have to be this brutal towards them?" Mount Lady replied, creeped out by the pictures of the villains this Batman has beaten.

Eraser Head looks at the video taken from the bank. It shows footage of the Batman sneaking up the criminals and knocks them out cold. Then place some kind of device on him which spreads out wires and patches on the other men, as the center of it brings them together and shot up into the roof. 'Like the guy's style.' He thought to himself.

"Black, gray, and that yellow belt, he sure does have style." Best Jeanist comments.

"There's also a peak of his popularity. It seems that after he saved that girl and stopped the bank robbery, he's gaining some popularity." All Might state.

Endeavor scoffs "So a Vigilante became popular overnight? What makes him so special?"

"He's placed Number 3 in the Hero Popularity." All Might have clarified.

"This guy must be a true cowboy." Snipe comments "But despite him bringing results, we can't deal with outlaws."

"Yeah, this vigilante is making us look bad." Mount Lady comments.

"But this guy isn't interested in popularity the slightest." Mount Lady replied, "He didn't even stop for an interview."

"If this guy thinks he's too good in not sharing about who he is to the public, he's no hero. If anything, he's a villain. Operating in doing a Pro Hero's work without unauthorized!" Endeavor states causing the heroes to argue about Batman.

"Enough!" All Might declare as he stands from his seat. "The best thing to do is that we keep a watchful eye out for the dark-clad vigilante. If you must, detain him!"

The Pro Heroes agrees to All Might's suggestion. They must keep on a look out for the dark vigilante.

/

In a dark and secured area, the Batman is now in a lab as he walks down to a large computer. He removes the black cowl from his face, as he sits on his chair.

The appearance of the Batman was the look of a normal boy, looks no older than 15. He has dark, green bushy hair, gray dull eyes, freckles, and his skin looks as if it lacks any sun light.

"Following up our top story, the Batman strikes again this night preventing a bank robbery. But the Pro Heroes have announced that they will apprehend the vigilante any chance they can get. This is what Nezu has to say."

Speaking over is the rat hero Nezu, who spoke to the press "Yes, the Batman is the one who stopped the bank robbery this night. However, he isn't an official licensed hero. He may have good intentions, but the Heroes Association can't ignore the fact that this Batman doesn't answer to the law. Not to the Heroes Association, not to the police, and not to the government. It's best for civilians to keep on a look out for a man dressing up as a bat. Don't try to apprehend him, leave the Pro Heroes to deal with him."

The Batman gave a sigh, as he felt a pair of arms wrapped around his neck as well as something soft behind his head. "You should've seen this coming when you started this." She told him as she gives him a peck on his cheek. The girl appears to have pink locks, yellow eyes and cross-hair pupils. She wore goggles on her head.

"I did saw it coming." He replied showing his freckled face and his gray, dead eyes "I knew what was I doing but did it anyway. The Pro Heroes can't stop what I just begun."

"So how did my babies do? They did perfectly well, did they, Izuku-kun?" she asks him, revealing that she's wearing her short overalls but doesn't have a shirt on, showing that her chest is pressing behind his head.

"They did perfectly well, Mei-chan." Izuku respond as he turns around and kiss her.

/

Zsasz is seen strapped in a straitjacket as well as blindfolded. He's being escorted to his cell in his new home, Meikakuna Asylum. There he's been ranting through his restrain mask, cursing about a bat.

"Let me go! The Bat must die!" Zsasz rants as he tries to get out of his restraints.

"Please, Mr. Zsasz, calm down before you upset the other patients." The doctor replied as he has the nurses place Zsasz in his cell. "Now then, we'll start our sessions when-"

"I don't need sessions!" Zsasz growled as he tries to get out of his restraints "I need to kill the Bat! My 200th kill is at stake!" he shouts madly.

The doctor sighed as he injects Zsasz with a serum that can calm him down. Once Zsasz stops moving, he looks drowsy and went to sleep. "Once you wake up, Mr. Zsasz, I would like to hear more about this…Bat you're talking about." He said as he adjusts his round glasses as he walks away. The bald doctor held up a file as he walks down the shadows of the halls.

Izuku's harem:

Mei Hatsume, Ochaco Uraraka, Momo Yaoyorozu, Tsuyu Asui, Mina Ashido, Kyoka Jiro, Zatanna Zatara, Rose Wilson, Itsuba Kendo, Iraba Shiozaki, Fuyumi Todoroki, Midnight, Mt. Lady, Himiko Toga(For now).

So this thought came to me after reading some My Hero Academia fics and thought if Izuku can be Batman. So here's my iteration in him becoming the Caped Crusader.

And yes, he will have some enemies of the Batman's Rogues Galleries. Izuku will be a different person through personality wise. He'll be more of a balanced kind of Batman as he is mentally Batman, but at the same time has some of his old personality traits (example: observing others' quirks as well as their strengths and weaknesses) but he will be cold towards others on some occasions. But as Amanda Waller from Justice League Unlimited quotes: "No superhero cared about other people more than Batman."

So hopefully you enjoyed this and remembered to Fav, Follow, and Review!
