Izuku had expected many things when he had All Might's offer to become his apprentice. Hard training, impossible tasks, and days of pain and recovery. He wanted all of that and more if that is what it took to become a great hero! Walking with All Might to some place he wouldn't even tell him about? Izuku hadn't seen that coming.

Izuku had met up with his idol early that morning for his first day of training. He bounced with energy, ready to get started. 10 months were all he had to be ready for U.A. He couldn't afford to waste a moment of it. Izuku practically face planted when All Might declared that they would be going to a special location before they started training.

Izuku cried that he had school later that morning and didn't have the time, but All Might ignored his words. He grabbed Izuku by the scruff his shirt, vomited some blood, and pulled him all the way to the train station.

They had taken a train farther out of the city and then began to walk even farther outside. All Might gave Izuku no hints on what they were actually doing. Every time Izuku had asked a question, All Might would wave him off and say "Be patient. This is the first step of your training,".

Izuku wasn't sure how traveling was related to training in anyway, but who was he to question All Might's teaching methods. He clearly didn't know what being trained to be the next Symbol of Peace entailed, so he might as well follow the man's lead. That didn't mean he wouldn't think about how ridiculous this situation was though.

After what felt like an eternity to the boy the duo reached their destination. Izuku was floored. His eyes shined with admiration as he gazed upon the building in front of him.

"U.A High!" Izuku exclaimed. "The top premier training academy for Heroes!"

All Might was surprisingly stoic compared to his star struck apprentice. He gripped the back of Izuku's shirt and dragged him through the gate, without so much of a word. Izuku's fangirlish babbling quickly dissolved into unrelenting questions, as his heels left trails behind him.

"Why are we here? Is it for training? Are we going to train at U.A?!" Izuku fired off.

All Might covered the green haired boy's mouth to silence him.

"Be quiet. Everything will be answered soon. Just follow me," All Might ordered. Izuku nodded, eyes wide open.

The duo walked to the front door, only to be greeted by a man. He had shoulder length black hair that slightly covered the front of his face along with a half-shaved beard and small mustache. He looked exhausted, with dark bags under his eyes. He had on bandages that were loosely wrapped around his neck in a scarf-like fashion. Finally, he had on a long-sleeved shirt and pants, both in black.

Izuku needed no introduction for this man. He recognized him as the Eraser Hero, Eraserhead. He was an underground hero due to his hatred of the press. Izuku had only seen blurry photos and read some things in forums about the hero, but to see him in person different. All Might raised a hand in greeting to the man. Izuku noticed how forced it was.

"Aizawa, nice to see you again," Aizawa didn't reply. He was too busy staring Izuku down.

The boy met the hero's eyes and tensed. He was studying Izuku, as if trying to find some sort of weakness to exploit. It was a skill Izuku knew many heroes cultivated over time. A hero must be prepared in every scenario when facing an unknown opponent, so they must be able to find any kind of opening to exploit.

He didn't falter though. Izuku met Aizawa's gaze, without blinking. His nervous shaking did ruin the whole "not a weakling" image he was trying to convey. After a minute Aizawa blinked and turned away.

"We got everything set up," Aizawa pointed over his shoulder into the building.

All Might nodded. "Good, then we're ready,"

The two senior heroes made their way into the building, prompting the boy to follow. As they walked, Izuku gazed around in wonder. This was U.A high. Not many people, barring students and faculty, ever got to see the inside of it. Izuku clenched a fist. He promised himself, he would walk through these halls again one day, but not as a guest. He would be a student at this academy.

Turning his attention away from the scenery, Izuku instead looked towards the pro heroes in front of him. He watched them curiously, as they walked in silence. Izuku could see clearly the two knew each other. The air was too thick with tension for them to be strangers. Izuku could practically see the animosity rolling off them.

They stopped in the middle of the hallway. Izuku peered past the duo. There wasn't anything around for this stretch of hallway. That begged the question, why were they stopped here?

As if hearing his question, Aizawa answered it by knocking on the wall three times in succession. Suddenly it split right open, revealing part of the wall to actually be a hidden doorway. Izuku squeaked in surprise.

"A hidden lair?" Izuku cried. Just like in the comic books!

Aizawa rolled his eyes at the boy and walked in. There was a staircase that extended downwards, going deep underground. All Might turned to Izuku.

"I am going to ask you now that you don't reveal anything you learn beyond this point to anyone," All Might's eyes were piercing. "This is life or death,"

Izuku gulped. "I promise," He vowed.

All Might nodded. "Good, now follow me,"

Teacher and Student caught up to the lethargic man and followed him down. Lights lined the walls, giving enough light for Izuku to see the stairs in front of him, but not enough for him to see farther down. Eventually they reached another door, which Aizawa punched a passcode into the keypad adjacent to it. It slid open.

Izuku was once again wide eyed and gaping at what was hidden beyond the doors.

In front of him was a laboratory. It looked like something out of a science fiction movie. Advanced pieces of technology were scattered around, along with more normal equipment. That wasn't the most shocking sight though. No what was even more shocking was the people in the room.

Izuku had never been in such close proximity to so many pro heroes. Sure, he had seen many of them in action, but to be able to just walk up to them, it had him in a state of awe.

Off to one side was the second strongest hero in the world, Endeavor. He leaned against the wall, arms crossed, and seemed to glare at nothing in particular. Not too far off from him were the heroes Cementoss and Ectoplasm. On the other side of the room was the Space Hero, Thirteen, and the 18+ only Hero, Midnight.

Then there was the last three ocupants of the room. They stood in front of a large table with something on it that Izuku couldn't make out between them. He didn't recognize the item, but did recognize the heroes. Present Mic, Recovery Girl, and the President of U.A, Nedzu.

They heroes, minus Endeavor, seemed to be in the middle of a lively conversation, which ended when the trio walked in. Aizawa yawned and took a spot next to Present Mic leaving All Might and Izuku as the centers of attention.

"Ah All Might!" Nedzu raised a paw in greeting. "And you brought your young apprentice as well, perfect,"

"Yes," All Might coughed some blood up and nudged Izuku. Izuku's face flared red with embarrassment. He bowed shakily.

"H-hello I am Midoriya I-i-izuku!" stuttered out of his mouth.

Some of the heroes chuckled at the boy's obvious nervousness. All Might face palmed .

"I guess it's time we explain what's going on here," All Might stated.

Nedzu took the reins from there.

"We are to understand that you have accepted All Might's offer to become his apprentice correct?" Nedzu asked.

"Yes!" Izuku spoke loudly. "I want to become a hero more than anything in the world,"

Nedzu smiled at his enthusiasm. "That's good. I assume All Might also explained to you what One for All is then?"

Izuku nodded.

"One for All is a powerful quirk, one that has made All Might a Symbol of Peace," Nedzu explained. Endeavor gave a snort, shooting some flames out of his nose, at the sentence. Nedzu wasn't deterred.

"I assume you don't know what that really means do you?"

Izuku hesitantly shook his head. All Might was a figure of the people. His power and heroism made him someone that everyone could look up to feel safe knowing he was out there defending them. Things had changed though. He had gotten glimpse on what was behind the curtains. All Might wasn't some invincible hero who could not be defeated. He was a man, just like any other, and he could be killed just as easily. The injury was proof of that. For someone to be able to do that to All Might…Izuku shivered at a villain that strong.

"A Symbol of Peace is someone for the people to look up to. It's someone who keeps the strongest evils at bay. If he were to be gone from this earth," Nedzu's look turned dark. "It would be a challenging time, keeping the villains from rising,"

He stared into Izuku's eyes. "The villains are waiting. They know All Might is hurt. They know he is running on limited time. All they have to do is sit around, plan, and accumulate more power until finally," Nedzu left the last part off, but Izuku knew what he meant.

It chilled Izuku to his bones thinking about that. A world without All Might. A world with no Symbol of Peace. It would be chaos.

"That's why you are here," All Might interjected. "I do not have the full power I once had. That is why we need you, Young-Midoriya, to take my place and become the next Symbol of Peace,"

Izuku was slack jawed. "B-b-b-but I don't even have a quirk!" 'Or training!' he mentally added.

Nedzu nodded. "It is true, you are quirkless. The original plan was for you to train and inherit All Might's quirk One for All, but-,"

"Things have changed," All Might took over. He clenched his fist in anger. "There have been rumors that my enemy, the one who gave me my injury, is grooming a successor to take his place. We don't know who they are or how strong they could be, but if he becomes even stronger than his teacher, we will be in trouble,"

"Who is this person?" Izuku asked.

"A man who goes by the name, All for One," All Might spat. "He has a quirk that allows him to steal and give out quirks to anyone he desires. He's been around since the birth of quirks and has fought against every predecessor of One for All,"

"He's that old?" Izuku gulped. Here was a man with the power to steal quirks and has been around since the birth of quirks themselves. He's fought and beaten every user of One for All since its birth. What chance did Izuku have!?

"Old and injured as well," All Might reassured. "He isn't able to be as active as he once was since our last battle. That is why he is training an apprentice. He needs someone to take over just as I do,"

Izuku looked to Nedzu. "You said the original plan was for me to inherit One for All?"

Nedzu nodded grimly, folding his arms behind his back. "Yes, but we are worried. We don't believe One for All has the power to take down someone like that by itself anymore. That is why we created this,"

Izuku moved to the table behind the principal who stood upon it. The other heroes in the room surrounded the table as well. The boy marveled at what rested there.

It was a fingerless black gauntlet that extended from the hand all the way to the elbow. On the top of the wrist a black dial with a purple X shape on it and a small button on the side. Six clear tubes total were attached to the base of the dial. Four extended from the corners and connected to the sides of the wrist. Another extended out wards in a straight line, to the elbow. It connected three evenly spaced tubes that also wrapped around the arm horizontally and connected at the sides. The final tube was opposite of that and extended from the base to a half dome on top of the hand, which had 2 purple lines on it. Looking down the dome, Izuku saw a hidden blade inside of it.

"This is our equalizer," Nedzu spoke with pride, circling the gauntlet. "This is what will make you a Symbol of Peace,"

"What is it?" Izuku wondered.

"A weapon," Aizawa spoke up with his apathetic tone. "And you have great honor of using it,"

Izuku studied it. He could see how it was a weapon. The blade was obvious enough. Other than that, though it seemed very lackluster.

"This is a device that has been in development for a long time," Nedzu said. "This can grant you the ability to use more than one quirk,"

"Like All for One?" Izuku asked bewildered.

All Might nodded. "Exactly,"

"If we have something like this then why doesn't All Might use it?" Izuku was confused. "Or another pro hero? Why don't we get more and have multiple heroes use them?"

All Might and Nedzu seemed to hesitate at the question. Aizawa didn't have this problem.

"Because they would all die,"

Silence permeated the air.

"This is a very powerful device," All Might said. "But also very dangerous. The risk matches the reward,"

Izuku pondered for a moment. "How does it even work?"

"We received the DNA of someone with a Copy quirk. It had the ability to replicate any quirk the user had touched for 5 minutes. They would be able to use the quirk with no strain to their body at all and have instinctive knowledge on how to use it. We used their quirk as a base for the device," Nedzu lectured.

"The only downside to the Copy quirk is that after 5 minutes, the quirk would fade and be unusable unless they touch the person again. We counteracted that using One for All's method of storing power. We hope that by combining the two it will mutate enough to work,"

"One for All started off as two quirks that mutated together," All Might said. "We're hoping it will happen again,"

"And then you can just feed the device quirks and it will act as an on and off switch for whatever quirk is needed," Izuku mumbled in thought. He continued to talk to himself until All Might gave a slight cough. He clammed up after seeing the looks he was getting for his mumbling.

"Anyways, with this gauntlet and enough practice, you would potentially adapt your body to the constant changes, making your only weakness the original ones of the quirks," Nedzu explained.

All Might looked to Izuku. "This isn't what I had originally planned for you. Training for 10 months and then receiving One for All is a safer situation and even then, you must be at the peak of physical fitness to even survive One for All,"

Izuku knew that. He knew how dangerous this was. This device rewrote someone's entire body to fit the quirk it's giving them. He could still be a Symbol for Peace without it. He could train with All Might, inherit One for All and become a hero like that.

But would that be enough? Every person who has face All for One has apparently either lost or died. All Might got lucky and tied and that was a stretch anyways. Someone with that much power is out there right now training someone to become as strong as him. Izuku couldn't afford to be scared. He needed everything he could get to be the best.

"Midoriya," All Might brought him out of his thoughts. "In the process of doing this, there is a chance you will die from the strain. Do you really want to take this risk?"

All Might was concerned, Izuku could clearly see that. Training for One for All was simple compared to all this.

"What happens if I say yes?" Izuku stared Nedzu down.

Nedzu smirked. "The gauntlet will be surgically implanted into your arm and you will be given time to heal. Then we will spend the rest of the time before U.A's entrance exam training your new abilities. Of course, you will also have a free ride to U.A for your services,"

Izuku gained a determined look.

"Can I make a phone call please,"

XXXXXXXXX

"Izuku where are you!" Izuku's mother, Inko, frantically spoke on the other end. "The school called and said you didn't show up today.

Izuku was off to the side, leaving the heroes to their own chatter. He glanced over and sweat dropped. They were really bad at hiding the fact they were eavesdropping.

"I'm fine Kaa-chan," Izuku reassured. "I… I found out that I got a scholarship for U.A today. It requires me to undergo some training before the next school year. I don't know how long I will be gone,"

"Training? But Izuku, how could you get into U.A? You don't even have-," Inko cut herself off with a gasp.

Izuku hung his head low. He knew what she meant. He knew where she was coming from. She didn't have the whole story. How could she possibly understand?

"Don't worry about that Kaa-chan," Izuku said. "Just know that… I'm going to become a hero,"

"Izuku," He could hear the waver in his mothers voice.

"I have to go Kaa-chan. I'll try and talk to you soon," Izuku hung up without another word. He clenched his hand around the phone, hair shadowing his eyes.

That was tougher than he had hoped. The worst was over though. This was just the beginning.

Izuku walked back over to the heroes.

"I'm ready," He said.

Nedzu snapped his fingers. "Recovery Girl, start prepping for surgery!"

Nedzu followed the healing heroine out. All Might glanced at Izuku before taking the gauntlet and following the others, leaving Izuku alone. With a bunch of pro-heroes. If he wasn't about to risk his life to become a Symbol of Peace, he would definitely ask for their autographs.

It was a nice and awkward silence for Izuku until one of them spoke up.

"So you're the one All Might chose," Aizawa drew his attention.

"You disapprove?" Izuku asked curiously, walking over to the pros.

Aizawa shrugged. "You have yet to prove yourself. All we know is All Might picked up some snot nosed brat off the street and declared him his apprentice,"

Izuku was a bit insulted, but would give him that one.

"Give the kid a break there Aizawa, he's probably already nervous enough," Midnight elbowed the dry-eyed teacher.

She smiled kindly at Izuku. "It's a brave thing you're doing here today. I'm surprised you aren't nervous,"

Izuku gave a hesitant smile back. "I guess I'm still kind of shocked. The nerves haven't caught up yet,"

"Why are all of you here anyways?" Izuku asked. "I get that you all know All Might's secret and the gauntlet, but why attend this?"

Present Mic grinned. "We wanted to see you listener!"

Izuku blushed slightly and pointed at himself. "Me?"

"Even if we don't know why, All Might has chosen you for a reason. We were all curious to see what kind of person would be inheriting our quirks," Thirteen stated.

Izuku's eyes widened considerably. "Inherit your quirks? You all donated your quirks for this?"

"Why of course," Cementoss said. He looked over to the glaring Endeavor. "Some of us more reluctantly than others,"

Izuku took a quick peak back only to turn back instantly. He could feel the #2 hero's eyes burning into him.

"What's wrong with him?" Izuku whispered.

"Don't take it to personally," Thirteen said. "Endeavors had a chip on his shoulder when it came to All Might for years now. To now give up part of his own power to help his rival's successor take the #1 spot is agonizing to him,"

"Then why did he do it?"

"He's a jackass," Aizawa yawned. "But he's still a hero at heart. No matter how shitty of a personality he has,"

Izuku winced. "That bad?"

"Massive temper," said Cementross.

"Extreme inferiority complex," Midnight rolled her eyes.

"And enough ego to fill all of Japan," Ectoplasm ended.

"Sounds like Kacchan," Izuku mumbled.

"Friend of yours?"

Izuku scratched the back of his head. "Sort of. More like frenemy,"

The pro's nodded in understand. It made Izuku wonder how many relationships they had like that.

The doors creaked and All Might stood in the opening.

"It's time," He said grimly.

Izuku nodded. Time to face the music.

XXXXXX

Izuku didn't remember much about the surgery. He was wheeled into a sterile white room. Recovery Girl stood there along with two assistants he couldn't remember. They were all dressed in white and wore masks, so it made the details a bit fuzzy.

They placed a mask onto his face and strapped his body to the table. Then the anesthetics kicked in and he was out like a light. He dreamed. He dreamed of a future, where the world was safe. He was a world renown hero who inspired everyone, all with a smile on his face.

It was a good dream while it lasted. Pain shot through his body, interrupting his vision of the future. He wanted to scream out, to yell, to call for help, but he couldn't. His body wouldn't move. His voice was silent. He was utterly alone, trapped within his own head in a tornado of pain.

It felt like an eternity until finally it stopped. Izuku didn't dream after that. He lied there in the abyss of darkness, resting and enjoying the break from the torture.

He briefly woke up for a few seconds. All Might's concerned face was the first thing he saw. It quickly morphed into a relieved smile that told Izuku he was ok. He had made it. He survived.

"Rest now Young Midoriya," All Might patted the boys head, as the darkness claimed him once more. "You have much ahead of you,"

He later learned it was a few days before he came to. The surgery itself had taken almost a full day, between implementing the gauntlet into his arm and keeping him from dying during and after the surgery. He was resting and recuperating for a few days, while they took the final step and began loading the quirks into the device.

Izuku was in a white room. There was a mirror off to the side near a desk, filled with scattered documents. He himself lied in a standard hospital bed, with the curtain pulled back. The only thing he had on him was a hospital gown and the gauntlet.

Recovery Girl had come in to check on him. She told him he was healing nicely. That was a nice weight of his shoulders. She would be back in a few hours, as she had a meeting to attend. The gauntlet wielder could only assume it was to talk about him.

This left him alone in a white room, with nothing to do. So, he occupied his time by studying the gauntlet. First off, he really needed to think of a name for it. "The gauntlet" felt to dull for such a powerful device.

Other than that, Izuku got a better look at it as well. One big thing he noticed was the X he had noticed earlier wasn't actually an X. It was a lot more rounded, causing him to realize it was a butterfly, not an X.

That was kind of a letdown. Not that there was anything wrong with butterfly's, but it didn't have the same coolness factor that other animals had. Villains weren't very intimidated by butterfly's. Why was it on the gauntlet in the first place?

Pushing that to the back of his head, Izuku began to mess with it a bit. He was careful about it! He hadn't really been informed of how it worked yet, being unconscious and all, so he really tried to not accidently activate the thing. Who knows what damage could be done to his body.

Izuku push one of the buttons on the side. He yelped as the face plate suddenly rose up. The butterfly shifted into a purple diamond and a black silhouette of a person appeared. It was hard to see, but from the outline Izuku could make out some key features.

The figure looked to be of normal human proportion, but their arms were different. The hands and forearm seemed to bulk out, as if they were wearing armored gauntlets. It wasn't like Izuku's though. Izuku's was more for fitted and made to not add to much mass to his arm.

Izuku twisted the dial and the figure changed. It was a similar figure, but instead they looked to be wearing a helmet. Another twist, a headset. One more and they had tubes on their arms.

Izuku continued this process for a bit longer. He continued to mess with the gauntlet until the door opened.

Nedzu appeared with a hand raised in greeting.

"I see you aren't dead Midoriya-san!" Nedzu sounded cheery, hopping onto Izuku's bed.

Izuku nodded. "I noticed," Izuku scratched the back of his head with a slight laugh.

Nedzu nodded his head, before placing a paw on his chin.

"You've had some time alone with it now. How does the gauntlet feel?"

Izuku raised his arm in front of his face. He ran his eyes over the device before replying.

"Natural," That was the best word to describe the feeling. He didn't feel like he had some device on his arm. It felt just like a normal arm, minus some soreness and a little added weight.

"That's good," Nedzu said. "A little more time and soon we can begin training,"

Izuku's eyes lit up and he sat a bit straighter in his bed. "Training?" He asked excitedly.

Nedzu once again nodded. "Oh yes Midoriya-san, training. I'll be one of your personal teachers along with a few others,"

Izuku was vibrating in his bed. He was gonna be trained by pro heroes! More importantly, he would get to feel what having a quirk actually felt like!

A soft paw, stopped his motion. Nedzu placed a hand on the boys shoulder, which considering his size, put him quite close to Izuku.

"Don't let my appearance fool you," Nedzu's eyes gleamed with sadistic pleasure. "I may be cute and furry, but I'm also a pro hero,"

Izuku lent farther back in his bed, in a poor attempt to get away from the animal.

Nedzu patted the boys shoulder and hopped off the bed.

"Rest up Midoriya-san," Nedzu waved, making his way out. "You'll need it,"

Izuku flinched when the door slammed. This was his dream. So why did he have a feeling it was going to turn into a nightmare?


So here I am again. I watched a TV show, got inspired to make a My Hero Academia crossover, and then complicated it beyond what is needed. I could have just made this a Ben 10 Crossover and Izuku could have transformed into aliens (which I would call mutated quirks). BUT NO! I had to take it to another level, just like Dead Hero. Only I guess I started to make this original from the beginning instead of 4 chapters in.

Speaking of that, I'll most likely go back and edit Dead Hero to flow a bit better. Won't rewrite it, but might have some new information in there, so if your a fan of that story stay tuned.

I was just watching a lot of Ben 10 when this popped into my head. I plan on doing some drawings for each of the quirks to show you guys what they look like. If you didn't get it before, each has there own hero costume to them, which basically will be Izuku changing clothes. I'll have a link to the gauntlet and everything soon, but for now the Cover gives u a cropped idea of what i'm going for.

I'm not gonna go crazy with the whole different quirks thing, because it also means i have to draw Izuku in a different costume/think of a costume for him that goes with the quirk, but I'll need more eventually. If you don't get with what I'm going for, the quirks all come from Pro-Heroes... and possibly non pro-heros later. You'll see next chapter, but the quirks aren't exactly the same as there doners, as to not make the actual quirk user redundant. I mean who needs them if you have Izuku then?

More on that later.

ANYWAYS if you guys enjoy this story and want to see it exist, review, favorite, follow, share it with a friend or whatever. Hopefully you enjoy it.

My goal is to get my stories to be the top favorited stories in the My Hero Academia fanfiction section. Dead Hero's going good and I hope this catches up. I actually have a third story planned ONE THAT IS FULLY ORIGINAL AND HAS NO CROSSOVER ELEMENTS! Yeah, speaking on that, I won't have a lot of crossover stuff with this one. That's mostly for Dead Hero to do. The only relation to Ben 10 that this story has is the watch that transforms someone into a hero and even then the gauntlet has some big differences then the Omnitrix.

PLEASE Leave some suggestions for Gauntlet names. I need something cool.
