In a world where 80% of the population was born with mysterious powers called Quirks, there is a boy. His name is Izuku Midoriya, and his dream is to be a hero. But he had a problem. With 80% of the population being born with these powers, the remaining 20% were normal people, and Izuku was unlucky enough to be born a part of that population. Because of this, he suffered a lot from the age of four.
Throughout his school life, Izuku was bullied for simply being someone without a Quirk. Even his former childhood friend Katsuki Bakugou made his life hell. So much so that, to make the boy's psychological worse, Bakugou nicknamed Izuku the name "Deku", which means useless, defenseless and among other bad things.
But not everything was bad in the boy's life. Even suffering at the hands of his classmates, teachers and his tormentor, Izuku didn't give up on his dream of becoming a hero. It's because? Well, I believe that the most obvious reason, and that most of you already know, is because of a hero. Japan's current Number One Hero: All Might. Izuku is such a fan of this hero, he even watched All Might's debut video thousands of times, where he saved 100 people in a short time. But the other reason the boy wasn't unhappy with his life was his family. Composed by Inko and Hisashi Midoriya. Even knowing that his son was born a Quirkless , his parents always supported him and helped him as soon as possible, especially his father.

If Hisashi were a hero, he would be Izuku's number one hero pretty easy. Until, a tragic thing happened that would change his life. Hisashi Midoriya died. This shook the Midoriya family, particularly Izuku. It was very painful for him. But even so, Izuku didn't give up and decided not to cry, because that's not what his father would want. Since then, from time to time, Izuku would do little exercises at his house. It wasn't a big deal, but he got some muscle out of it. But little did Izuku know that from the age of 14, his life would change for the better...but also for the worse.

After finishing another horrible day at his school, receiving an "advice" to kill himself from Bakugou, meeting All Might and discovering his secret, saving his ex-friend from a villain made of slime who has tried to kill the greenish before , and from being scolded by the pro heroes, Izuku was blessed at the end of that day.

All Might, who had said that the boy couldn't be a hero without having a Quirk, saw the boy spring into action to save the Bakugou and regretted what he said. The hero looked for the protagonist, and told him the following phrases: You too can become a hero. That phrase made Izuku's heart rejoice, and made him burst into tears. After all, the only person who had told him that the boy could be a hero was his late father, and seeing his idol speak those phrases; made him very happy. And it was from here that Toshinori Yagi chose Izuku Midoriya as his successor to receive One For All. But for that, Izuku needed to train his body to be able to wield the power. So for that, he would need to go through 10 months of training to pass this power on to him. All this before the entrance exam for UA, the hero school the protagonist wants to apply to.

But little did Izuku... in fact, little did the world know that this wasn't even the tip of the iceberg. In this world, there are four turtle brothers who face an evil that has no good intentions with the world. This evil came to Japan and these four brothers came together to stop this evil.

Returning to our protagonist, it's been 5 months since he started his "hellish" training. After all, he had to clean up an entire beach that was full of garbage. It would have been a lot worse if he'd been the way he used to be, skinny. But thanks to the little exercises he did, this training was less terrible than it would have been. But even so, it made him tired, but on the other hand, that was good, because his physique was much better compared to 5 months ago.

Anyway, it was night in Musutafu. 20:00 to be more specific. He just went out to the market with the purchases his mother asked for. Inko didn't want to make her son go because she worries about him so much, but Izuku insisted, saying it would do him good to walk a little more. That was kind of true. Izuku just wanted to do this to do more leg and foot exercises, to see how much he's improved.

Izuku: 'Let's see. Recipes for Katsudon: Check. Lettuce: Check. Pisces: Check. Milk: Check. Orange juice box: Check. Great, I've got it all.' - Izuku was already at the market gate, and after checking if the purchases were there, he left for his house.

Izuku: 'It's been 5 months since All Might chose me as his successor. But to be able to wield his power, I need to improve my physique even more. I understand that, but I didn't think this workout would be this painful. Well, at least this is showing a positive result. I got a little stronger than before, but I still need to improve if I want to be a hero. So I'll be able to save people with a smile on my face, just like All Might and just like...' - Izuku stopped walking when remembering a person - 'Just like you did that for me, dad...'

Izuku got a sad look. Even though it was 6 years after the loss of his father, it still messed with him. But Izuku won't let that shake him that easily. He got a determined look, looked at his right hand and clenched his fist.

Izuku: "I will make it ." - He said with a smile.

Izuku continued his walk, and just as he was about to turn the corner, he saw something suspicious. He saw people wearing strange clothes. They looked like ninja clothes, only they had a symbol that looked like a foot, just painted all over red. Some of them had swords, axes, scythes with chains (Also known as Kusarigama) and not to mention they also carry shurikens and kunais with them.

Izuku: 'But what is this? Who are these people? Is it some kind of cosplay reunion or something else? No. Because if it was, why would they have these weapons with them? Are they villains? I better take a closer look.' - Izuku saw that those strange ninjas entered an alley, and in the most silent way possible, the boy approached.

He knows that doing so would be risky. After all, if they were real villains and saw Izuku, what would he do? And if they weren't, how would he know? Izuku wanted to be sure, especially in this neighborhood where he and his mother live close by.

Izuku entered the alley, but in order not to risk making a noise, he left the bag hidden in a pile of discarded boxes. That way those people wouldn't hear him approaching, and nobody would pick up their groceries. Well, that's what he expected. That done, the boy leans against a corner wall and sticks his head out to see what these people are up to.

He saw those people carrying some boxes and putting them in a truck. But one of these ninjas didn't hold the box very well and accidentally dropped it. Making Izuku have a vision of what was inside. It appeared to be cylinders with a slimy green liquid inside.

Izuku: 'What is this?' - His attention was soon stolen by what seemed to be a roar that came from inside the truck.

Inside that truck, some kind of tiger came out, with an eyepatch over its left eye. He didn't have a tail, and he wore an outfit that looked like a character from those old western movies. So much so that he has two holsters on either side of his legs, and in them he has a gun that looks like pistols. This tiger had a furious face, and his face made Izuku shudder in fear.

???: "Be careful, newbie!"

Novice Ninja: "I'm sorry, s-sir!" - The Ninja who seemed to be the rookie, bowed as a sign of asking for mercy.

???: "You're lucky you didn't have to break this, and the boss wasn't here. Otherwise, you'd die right here and now." - He said with a lot of coldness in his tone, which made the Ninja shiver - "Take this and put everything in the truck. NOW!"

Without saying anything else, the rookie Ninja did just that. He took that vial and put it in the box, then put it in the truck. Izuku no longer had any doubts. Those people are certainly too suspicious.

Izuku: 'Oh boy! I better call the police or call some hero. Maybe All Might will help.'

In the midst of desperation to try to get his cell phone, Izuku accidentally drops it, which causes a noise.

Izuku: 'Damn it!' - Izuku was sweating liters. And he heard someone approaching him.

From the way the person was walking towards him and the sound that sounded like a gun, it was definitely that tiger that was walking towards him. Izuku wanted to run, but his fear was so much that it felt like he was paralyzed. He was pretty sure he was going to die. Until...

"Sir, look!"

[Insert soundtrack: Squirrel Formation - Steve Jablonsky (Start: 0:56)]

One of these Ninjas pointed to the top of a building, and everyone, including Izuku, saw 4 silhouettes up there.

One of them is a turtle with a blue stripe on its face. He has two katanas on his back, two military tactical bags on his waist, shoulder protectors made of metal, black bands around his two wrists, and he wore ninja pants. His name is Leonardo.

The other turtle wears a purple headband. He has a Boostick on his back, he wears glasses and on his forehead he had a device that looked like a microscope eyeglasses. In addition to wearing a utility bag, he wears beige pants with protectors on both knees. His name is Donatello.

The other has a red stripe across his face. He has two Sais at his waist, a utility bag at the front of his waist, his wrists are covered in ropes with what looks like some kind of Kard Chuek, and he wears big shorts. His name is Raphael.

And last, but not the least. We have the turtle that wears an orange headband. He has two Nunchakus on his waist, a Skateboard with small rockets embedded in his back, military tactical bags on his waist, and wears black shorts. His name is Michelangelo.

These are the Ninja Turtles and they have their eyes focused on those ninjas, and it looked like their eyes were blank.

Izuku: 'Who are they?' - Izuku couldn't quite see who they were exactly, but he felt that they weren't a threat to him.

???: "Catch them!" - He said as he ran to the truck and the ninjas took their weapons to attack.

Turtles jumped off the building and landed on the ground. With that, the ninjas advanced towards the four brothers, and the ninjas went towards them without taking their weapons.

Michelangelo jumped up and kicked one of the ninjas in the face, until another tried to attack him with his sword, but he couldn't as Raphael grabbed his right wrist and twisted it, causing the Ninja to scream in pain before receiving a punch. straight in the face.

But soon Raphael's attention goes to another ninja who tried to attack him with a scythe, but he dodged it and punched the ninja straight in the stomach, causing him to bow a little, but before he could fall to the ground, Raph grabbed him. your head

Raphael: ["Mikey!]"

Michelangelo: ["Bring it on!"] - Michelangelo turned his back, so that Raphael could put the ninja's head. And so he did.

Raphael rammed the ninja's head right into Michelangelo's hull, causing him to collapse in pain.

Raphael/ Michelangelo: ["High Five"] - The two clapped hands and broke apart to attack other ninjas.

Leonardo was dodging without much difficulty a Ninja that was attacking him with an axe, until he hit the ninja's hands, making him drop the axe, and then the Ninja took a punch to the chin and face.

Until another ninja appeared behind him; trying to secure the turtle with the Kusarigama's chain, but Leo saw this, and let the chain catch on his left wrist. After this happens, he pulls the chain with his right arm, making the ninja go to him. And when he arrived, Leo grabbed his face with his left hand, punched him twice in the stomach, lifted him in the air to knock the ninja straight to the ground.

Leonardo: ["You underestimated me."] - Said in English as he took the chain off his left wrist.

Donatello, who had just dodged a sword, kicked the ninja that attacked him in the leg and then gave another kick to the enemy's face, causing him to fall to the ground. Until he heard the noise of the truck moving, and there was no way they could follow them now, after all they were busy with the ninjas present. But Donnie was smart, so he took a device out of his utility bag and threw it right behind the truck, causing the device to stick to the back of the vehicle.

Unbeknownst to Donatello, a ninja was advancing towards him with a sword pointed at him, and Izuku saw it.

Izuku: "Hey, watch out!"

Donatello: "Huh?" - Donnie thought it was strange another voice that was not his brothers' voice, telling him to be careful. However, he put that aside when he felt the sword hit his hull. And to the ninja and Izuku's surprise, Donatello turned around with a smug smile.

Donatello: ["Really?"] - Donnie scowled at the ninja, before punching him right in the face, causing the ninja to fall to the ground - ["In case it wasn't clear, I'm a turtle. Study more, rare intelligence."] - He said before advancing towards another ninja.

With only six ninjas left, the Turtles decided to end it now. Raphael lunged at one of them and kept using his body to hit the other, causing the others to crash into the wall. Michelangelo dodged an attack with the axe, and then attacked the ninja with his own Skate, hitting him right in the face of the enemy. As he fell, Michelangelo looked at his skateboard and stroked it.

Michelangelo: ["My baby!"] - he said while hugging his skateboard.

With only 3 left, Leonardo headbutted a ninja, causing his enemy to be stunned, but he didn't have time to think, as Leo finished him off with a kick to the stomach, causing him to crash into the wall.

Donnie was using his staff to defend himself from the attacks of the penultimate ninja, who was attacking him with his sword, until Donatello hit the handle of his staff squarely on his opponent's foot, making him scream in pain. Donnie took advantage of this, swung his staff around and slammed into the sides of the ninja's torso, and spun around to give the last boost to the enemy's head.

Izuku: 'Wow! They are amazing!' - He thought with a smile as he saw the four brothers gathering to face the last ninja that was standing. And that was the rookie ninja.

[End of Soundtrack]

Novice Ninja: "S-Stay away f-from me, freaks!" - The Ninja advanced towards them to attack them with the sword in his hands, but Leonardo stopped his blow by grabbing the novice's wrists, making him drop the weapon. As he did so, he pushed him to the ground.

Lying on the floor, the rookie kept crawling away from them, until he stopped at the wall. He had no further escape.

Leonardo: "Listen here. If you don't want us to do something with you, then you better tell us what we want to know."

Novice Ninja: "I-I won't t-tell you anything." - Even saying that, it was obvious that he was afraid of them.

Leonardo: "Believe me. We can do this the easy way, or, Raphael's way." - He said while pointing to Raph, who kept hitting his hand on his fist a couple of times.

Donatello: "Trust me, you don't want it to be Raph's way." - Donnie said that as a signal for the rookie to speak up. He didn't want too much violence.

Leonardo: "Tell me. Where's the Shredder? What was in that truck? And why did he and Foot Clan come here?"

Novice Ninja: "L-look, I-I j-joined this clan a little t-time ago. So I don't know much."

Raphael: "You'd better not lie, you son of a..." - Raphael was going for the ninja, but Leonardo stopped him with his hand. As a sign of: "Leave it to me.", and Raph obeyed, even though he didn't want to.

Leonardo: "So tell us what you know."

Novice Ninja: "Look, all I know is, the foot clan left New York to come here because they made a deal with a group of villains here."

Izuku: 'A group of villains?' - Izuku was listening carefully, so much so that he stopped hiding.

Leonardo: "And who is this group of villains? Who are they? And where is the Shredder?"

Novice Ninja: "Like I said, I joined them not long ago. I was just an ordinary thug, that's all."

Raphael: "Tell us what we want to know!" - Raphael was losing patience. So much so that he punched the wall hard, causing it to crack and making the rookie freak out.

Novice Ninja: "A-A-A-all I know is that this group is called: "The League of Villains"! Look, I swear to God I don't know where the Shredder is, or why they're working together and or what they're up to! After all, this was my first job, and I didn't think I'd end up in this situation! I swear that's all I know!" - The Ninja was cringing as he puts his hands in front of him, hoping not to receive a blow.

Leonardo: ["Does anyone here know what this league of villains is?"] - Leo asked his brothers.

Donatello: ["I don't know, but I can look them up in our hideout. Maybe there's something related to them that we can find."]

Michelangelo: ["Guys."] - Mikey tried to get his brothers' attention, but...

Raphael: ["Whoever it is, let's find them and finish them off, to make them regret joining the Foot."] - He said as he pounded his fist on his hand.

Michelangelo: ["Guys..."]

Leonardo: ["Raph, think about it. If they left New York and join this "League of Villains", then these guys can be a heavy load. So we can't underestimate them."] - he said as he puts out his hand on the his chin

Donatello: ["Leo is right. We should be careful if we run into any of them. If the Shredder has made an alliance with them, then they can be formidable enemies."]

Michelangelo: ["Guys..."] - Mikey raised his tone a little more, but...

Raphael: ["Okay okay, whatever. We beat them in the face anyway."]

Donatello: ["That's if we don't alert the heroes here and don't draw too much attention."]

Leonardo: ["That, and also something else, Raphael. Remember what Master Splinter said..."]

Leo/Raph: ["Never underestimate your enemy's ally."]

Raphael: ["I know that very well, Leo. I still remember the last time I underestimated someone..."] - he said while remembering the times he underestimated an enemy. Even more so when he trained with Splinter.

Michelangelo: ["GUYS!"]

Leo/Raph/Donnie: ["What's up, Mikey?"]

Michelangelo: ["We have a little problem over here."]

Leonardo: ["What little problem?"]

Michelangelo didn't say anything, he just turned slowly and looked in one direction, and when the brothers looked at where Mikey was looking, they turned pale.

They saw Izuku standing there looking at them, and he had a surprised face.

Izuku: "Whoa..." - Izuku already has a better view of who they were. He was shocked at first, but he let it go when he saw what they did.

Donatello: "Calm down, kid. No need to panic. We won't do you any harm." - He said while showing his hands to the greenish man. As a sign that they weren't going to do anything to him. But that's not why the protagonist was like that.

Izuku: "You... were... amazing!" - Yes. Izuku entered his fanboy mode. And that took the brothers by surprise.

Leonardo: "Uhh... what's it like, kid?"

Izuku: "You were amazing! The way you fought as a team was amazing! Are you new heroes?! What kind of Quirk do you have?!" - Izuku thought the brothers were like that because of a Quirk. But...

Michelangelo: ["What is a Quirk?"] - Mikey whispered to Donnie

Donatello: ["I think he's referring to the powers that people have these days."] - Donnie whispered turning to Mikey. They spoke in English in the hope that Izuku doesn't understand what they're saying, and that he won't hear.

But to their surprise, Izuku heard and understood what they were talking about. Izuku is a studious and intelligent person, so he understands the English line.

Izuku: "Wait a minute, you mean you're not like that because of a Quirk?" - his question made Leo, Raph and Donnie despair. Until Raph decided to act.

Raphael: "Oh, so..."

Michelangelo: "We are not. Why? Ouch!" - Raph and Donnie punched Mikey on the head, which made him whimper and got a comical bump on his head. Leo hit his hand in the face.

Izuku was in shock. He's seen many Quirks where the person had a physical change. Those are Mutation Quirks, and he thought the four brothers had that. But to his surprise, it wasn't. Leonardo saw Izuku's state of shock and became worried.

Leonardo: "Hey little guy, are you okay?" - he said while waving at him.

Izuku didn't say anything.

The shock was such that he fell hard to the ground, passing out. And that despaired the brothers.

Leonardo: "Hey, hey! Little guy, wake up!" - He said while shaking the boy's shoulders.

Raphael: ["See what you did, Mikey?!"]

Michelangelo: ["I'm sorry!"] - Said while shedding comical tears.

Donatello: ["Guys, we'll see about this boy later. Now we have to..."] - Donnie stopped talking when he saw where the ninjas were lying, and to their surprise, they all disappeared.

They became so focused on Izuku that the foot ninja took advantage of the situation and left.

Donatello: ["Yeah, we have one more problem."] - he said while scratching his head

[Timeskip: 2 minutes. Bringing the chibi Leonardo and Donatello trying to wake up the chibi Izuku. While the chibi Raphael was chasing a chibi Michelangelo.]

Izuku was starting to wake up and gradually his eyesight improved, until he saw the four turtles looking at him with worried eyes.

Leonardo: "He's waking up. Hey boy! Is everything okay? Do you remember who you are?"

Donatello: "Do you know where you live and who you live with?"

Raphael: "How many fingers do you see here?" - Raph kept showing his three fingers to see if Izuku was thinking well.

Michelangelo: "Do you prefer Marvel or DC?"

Mikey's question made the brothers, including Izuku, look at him with a "Is this for real?". Until Izuku came to his senses again, and dragged himself a little away from them.

Leonardo: "Hey, calm down, little guy. We won't do you any harm."

Raphael: "Unless you give us a reason to do so." - Raphael's comment made Izuku shiver a little

Donatello: "Raphael, you're not helping." - Donnie gave his brother a little elbow in the arm.

Raphael: "Calm down, I was just kidding. Hehehe, look at his face. He believed." - He said while chuckling.

Seeing that they wouldn't do anything bad to him, and seeing that they're just trying to calm him down, Izuku slowly stands up.

Izuku: "W-who are you?"

Leonardo: "Little guy, we are ninjas." - He said while making a small reverence.

Raphael: "Mutant Ninjas." - He said while smiling and leaning against the wall.

Donatello: "Basically, we are turtles."

Michelangelo: "Oh, and we're teenagers too. We're almost into adulthood, but we're still teenagers." - He said while smiling.

Izuku: "Hold on, so you're basically: "Teenage Mutant Ninja Turtles"?" - He asked with a finger on his chin.

Donatello: "It's like that right there, but I think "Ninja Turtles" is good enough." - He said while he had a comical bead of sweat on his head.

Michelangelo: "Oh, we could have a better name than that, right? Like, Shadow Heroes. Nightwatchmens. Or how about..." - Mikey was silent when Raphael put his hand in his mouth. brother for him to be quiet.

Raphael: "First: We don't need that. And second, we have bigger problems to worry about, and this kid is one of those problems." - He said while pointing to Izuku

Izuku: "W-what you me-mean?" - Izuku recoiled a little when Raphael pointed at him.

Leonardo approached him and placed his right hand on Izuku's left shoulder.

Leonardo: "What's your name, little guy?"

Izuku: "I-Izuku Mi-Midoriya."

Leonardo: "Right, Midoriya. I want you to try to forget everything you saw or heard here. Don't tell anyone about this or us. Don't get involved in this or involve the police or the heroes in this story. This is our problem and we'll solve it. Got it?" - Izuku nodded - "Good. Take care, Izuku Midoriya." - Leo patted the greenish man's shoulder and turned to his brothers - "Let's go, guys!"

After saying that, the four ninja turtles jumped and climbed the buildings, until they reached the top of one. Raphael, Donatello and Michelangelo already ran away, Leo had one last look at Izuku before leaving with his brothers.

Izuku: "What's going on...?"

Back to the Teenage Mutant Ninja Turtles, they were jumping from building to building, doing somersaults, pirouettes, or doing parkour. Until they jumped onto a street where no one was around, and unplugged the manhole cover and jumped in, but of course, one of them put the cover back in place. They ran through the corridors of the sewers, until they accessed a secret door that let them into their hideout in the sewers of Musutafu.

Their hideout didn't have much to compare to their house in New York. But it had enough for them to call home. Inside was an arcade machine, a punching bag, a training dummy, a small lab, a large computer with several screens, a kitchen, a large skate ramp, a small dojo, and a television for them to spend time watching. something.

Leonardo: "Master Splinter, we have arrived!" - He said as he got on his knees to his master.

He is an old and tall rat, but very skilled and strong. He wears a light red kimono, and on the back of this kimono was a symbol that appears to be a flower. The name was Hamato Yoshi, but now he has another name, Splinter.

Splinter: "I'm glad you're back, my sons." - He said before getting up - "So, how was it? Did you get any information?"

Donatello: "Not much. The only thing we find out is that, the Shredder came here because he has allies here. And from what we find out, they call themselves: "The League of Villains". Now what are their intentions, no we still don't know. So I'm going to research them and try to find their location."

Raphael: "And when we find them, we'll finish them off. We'll show this "League" the turtle power."

Splinter: "Raphael, we don't know what the Shredder's plans are or what this League of Villains is capable of. We're not in New York anymore, so the things here can be much more difficult than before. We must be patient."

Raphael: "Yes, sensei." - He said as he bowed.

Michelangelo: "Well, I'm going to have a pizza! I'm hungry." - While Mikey was going to the kitchen, Raphael went to the machine to play some games.

Donatello: "Well, I'll go to the computer and find out something about this league, and try to find their location of the foot clan. I put a tracker on that truck."

Leonardo/ Splinter: "Good job Donnie/Donatello."

Donatello walked to his lab and Leonardo got up to go to the couch. Splinter decided to ask his kids a question.

Splinter: "Oh, and have you been spotted?"

Splinter's question made the four brothers stiffen. Raphael froze while losing the game, Michelangelo didn't even care when he heard the sound of the microwave beeping, Donatello was shivering, and Leonardo swallowed hard. Splinter sees their reactions and sighed.

Splinter: "So you were seen..." - He said while putting his hand on his face.

Leo/Raph/Donnie/Mikey: "Sorry, master!" - they said as they ran and bowed in front of their father. Which made him sighed even more.

Splinter: "You should pay more attention. Do you even know who the person who saw you is?"

[Back to Izuku]

Izuku was already in front of his apartment door. He still couldn't believe what he saw and heard. After the turtles left, Izuku left the place as quickly as possible, but of course, he took back the shopping bag. Upon opening the door, he sees his mother in the kitchen.

Izuku: "Hi, Mom. I'm here."

Inko: "Oh, hi, honey. I was wondering when you were going to show up." - she said smiling.

Inko is a beautiful woman and a great mother. Even after Hisashi's death and having a child without a Quirk, Inko still took care of herself and loved her son very much. Even though she had doubts that her son would be able to fulfill his dream.

Inko: "Are you okay, son?" - She Said seeing that Izuku seemed to be distracted and she was worried that something happened to him that is affecting him.

Izuku: "Sure, Mom. I just need a shower. Hehehe! Anyway, here's the shopping." - Izuku left the groceries on the table and walked to the bathroom to shower.

Inko: 'I wonder what happened?'

Upon entering the bathroom, Izuku leaned against the door. That night was crazy. He had so many questions on his mind. Who were those people wearing those ninja clothes? Who is the League of Villains? Who were those turtles? If that wasn't a Quirk, then what was it? How did they get like this? But the main question he had in mind was:

Izuku: "Will I ever see them again?"
