"I can't get close! This power… it's too much!" Midoriya watched in awe and horror as All Might fought the inhuman Noumu. Next to him, Bakugou and Todoroki were pushed back by the force of the punches, each one exceeding 100% of All Might's power. The Number 1 Hero continued his assault. Blood trickling down his cheek. The pain he felt seemed to only fuel the rage he felt as he prepared his final blow.

"Remember these words… Plus…" He clenched a fist and threw his punch, causing the Noumu to gag before being launched straight into the air. "... Ultraaaaaa!" It flew out of the USJ building and well into the sky. All Might grinned before turning his attention to the final two: The Villain of Decay, Shiguraki, and the Warping Wrath, Kurogiri.

As All Might confronted the final two foes, Midoriya couldn't help but scan his master's body. 'He's wounded. What's more, he doesn't look like he has much time left.' He clenched a fist. 'If those guys make a move, he'll… he'll be…' He clenched a fist and prepared himself.

All Might stood straight. "So? What are you waiting for?" His frown hid his pain. "Don't tell me you're afraid now?"

Shiguraki stepped back, unnerved. However, Kurogiri narrowed his eyes. "Wait, look at him. He's exhausted." He leaned forward. "Noumu wore him out. This could be our last chance."

Shiguraki regained his composure and grinned. "I see… then there's still a chance to finally…" He rushed forward. "... destroy the symbol of peace!"

All Might braced. He knew he didn't have enough energy to retaliate, much less move from his spot. Once Shiguraki and Kurogiri reach him, that'd be it. He clenched his fists and readied himself.

"You stay away from All Might!" A new voiced yelled. The hero looked over to see Midoriya flying towards the villains, his leg broken from the powerful jump. The young hero had reared back a fist, ready to let out his attack. However, seeing his mentor at death's door caused something to click. The microwave he always pictured seemed to explode as his arm glowed bright red. The upper half of his costume seemed to tear as his body exerted an intense pressure. 'I-I'm going too far… this feels like nothing I've ever done before but… I have to try and save him!' The pain seemed to disappear as his resolve took over. "Smaaaaaash!" He threw his punch.

Time seemed to slow down as Shiguraki and Kurogiri had no time to react. The very air seemed to vibrate as the power of the punch sent the villains flying. Kurogiri quickly rearranged himself and got behind Shiguraki, who flew into the warp gate. Before the handy villain could be engulfed, he glared. "Damn… kid…"

Midoriya's punch didn't end at the immense wind pressure. The greenette felt as if his body was held in place in midair. The world seemed to stop as the very molecules surrounding his body seemed to heat up. He suddenly felt an intense lightheadedness before falling unconscious.

All Might put an arm up to block the intense pressure coming from Midoriya's attack. He stumbled back, coughing a bit. 'This power… Young Midoriya isn't ready to use One For All like this. I don't think I've ever been ready to use it like this.' When the area finally cleared up, All Might looked up at the area the young hero was. However, Midoriya was gone. "M- Midoriya!?"

Glynda Goodwitch patrolled the forest training grounds. She kept herself focused as she heard a rustling in the brush ahead. She sighed as a large black mass rushed toward her. The beast raised its massive claws in preparation to strike… only to be swatted aside with ease. Glynda blew a lock of hair from her face before approaching and finishing off the downed creature. "According to the scans, this should be the last one." She cracked her neck, sighing. The school year was going to be starting soon, which meant the annual clearing of the training grounds. 'Each year, more and more Grimm are showing up here. If we didn't clear them out every now and then, this place would be an unruly hive.' She checked her Scroll to take some final notes before preparing to head back. "Things should be clear for a little while. At least until the new huntsmen and huntresses come along-" Her musings were interrupted by what appeared to be a sudden earthquake. The area around her began shaking violently. "What the…!?"

The very air seemed to vibrate as a sudden bright flash of light blinded the huntress for a moment. Then, almost as soon as it started, the shaking ended. Glynda rubbed her eyes and looked at the scene before her. She put a hand to her mouth. "My God…" In front of her was a young man in extremely tattered clothing. She quickly rushed to his side. "Young man, are you alright?" She asked, slowly cradling the boy's head. When she received no response, she listened for a heartbeat before sighing in relief. 'Good… he's only unconscious.' She looked around, confused. 'But… where did he come from?' She examined his body and shivered. His leg and arm seemed to be grotesquely broken, the latter seeming to be extremely damaged. "What did this to him? Was this some sort of Grimm attack?" She quickly grabbed her Scroll. "I require assistance in the training sector. There's a civilian here with severe injuries!"

Glynda Goodwitch sat in the waiting room of the hospital. The young man was rushed to the hospital and, due to his injuries, was ushered into the Emergency Room. Glynda had to admit, she was a bit worried. His limbs looked mangled. Even with the most efficient use of dust and equipment, she wasn't sure if the boy would wake up with an arm. A hefty amount of time passed before one of the nurses came from the room. "Ms. Goodwitch, I have good news! The young man is going to be fine."

The huntress was surprised. "Really? Those wounds looked rather… extreme…"

"Indeed. But, with a good amount of dust and some of my staff's semblances, we were able to heal up most of the damage." She looked away, sadly. "However, I have to say, it was rough. The bones in his arm were completely decimated. It was like glass completely shattering." She closed her eyes. "Luckily, we were able to fix him up, but his arm and leg are going to need significant rest." She looked at the huntress. "Tell me, do you know what happened to him?"

Glynda thought for a moment. "I only found him in the forest. I suspect a Grimm got to him. What kind, I honestly couldn't say." She said. It wasn't really a lie. "Is it okay for me to visit him?"

The nurse nodded. "Of course. He's resting as of now."

Midoriya's head pounded as he slowly came to. He groaned as he stirred before trying to sit up. He winced at the sudden pain and finally opened his eyes. He found himself in a hospital bed, but the room seemed rather odd. The machines around him seemed different in a way. However, his eyes were suddenly drawn to his body. He donned a hospital gown and a cast over his arm. His leg seemed to be in a similar state as well. Midoriya fought through the pain in his head as he tried to remember what happened before he passed out. 'I remember… All Might fighting that brain guy… then…' His eyes widened as he suddenly saw flashes of Shiguraki rushing towards the pro hero. He sat up straight, panicked. "All Might- ugh!" The immense pain rushed back to him.

A hand was suddenly placed on his chest. "Slow down, young man. You are injured."

Midoriya looked over to find a middle aged blonde woman looking at him with concern written on her features. She gently pushed him back down.

"Who… who are you? Where are we?"

"Do not worry. I am a huntress. You're in the Central General Hospital. One of the best in Vale-"

"I'm sorry, Vale?"

The woman raised an eyebrow. "The Kingdom you're in? It's where I found you?" The young man's confused look didn't go away. 'Did this kid hit his head or something?'

Midoriya looked around at the room again. This whole situation was very strange. 'Something's wrong… I don't recognize any of this equipment. It looks different from what's used in a normal hospital. What's more, she mentioned I'm in… a kingdom? Vale?'

Midoriya's confused look prompted the woman to change the subject. "Well, do you remember anything before you passed out? You were in pretty bad shape when I found you."

"I… was at the USJ with my class… then villains attacked… is everyone alright?"

"USJ? I'm not familiar with the place."

"It's the training facility of U.A.? The hero school?"

The two stared at each other, confused. Each one tried to figure out what the other was talking about as a nurse suddenly entered. "Ah! You're finally awake!"

Midoriya shook himself from his confusion. "Uh, yes! Thank you!"

"No problem. You're lucky Ms. Goodwitch here found you." She looked through her papers. "Now, to start, what is your name?"

"My name is Izuku Midoriya."

"Where are you from?"

"Musutafu, Japan."

The women blinked a few times. "Um, pardon?"

"Musutafu? Near Tokyo?" He looked at the two's confusion.

"Ms. Goodwitch, do you know where these places are?"

"Unfortunately, no." She frowned at the boy. "This isn't the time for games, young man. We're trying to help you."

"But… but, I…" Midoriya looked down in shock. 'W-where the hell am I?'

Goodwitch sighed. "Nurse, could you give us a moment alone?" The nurse nodded before leaving. Goodwitch narrowed her eyes at Midoriya. "Izuku, you need to be honest with us, or we can't help you. How about this…" She pulled her chair closer. "Let's start with how the day began." Midoriya nodded and relayed the events to the woman. He told her about his class' rescue training and how the villains disrupted it. He told her everything leading up to his fateful punch. Goodwitch raised a hand. "Wait, you did that… to yourself?" She pointed at him broken arm.

"Uh, yeah. I can't… fully control my Quirk." He explained.

"Quirk? You mean your Semblance?"

"My… huh?"

"Nevermind. I must say, I'm finding all of this hard to believe. I've never heard of a school known as U.A. or of this 'All Might'. It's all sounding like… like something out of a comic book!" She sat back, huffing. 'He doesn't seem to be lying. What is going on?'

Ms. Goodwitch went to speak to the nurse, leaving Midoriya to his thoughts. The young hero laid down, thinking. 'From what she said, it's almost as if no one's ever even heard of All Might, much less Quirks! She had no idea where Japan or U.A. was… it's like none of it ever existed.' His mind flashed to the strange moment of his punch. 'I remember feeling strange as soon as it happened.' He put a hand to his chin. "I exerted so much energy with my punch… could it be that I… no, that's not possible… is it?" He continued mumbling to himself until the door opened.

Ms. Goodwitch entered the room, a stern look on her face. "Well, the nurse says you're free to go, but she'll be releasing you into my custody."

"C-custody?"

"Yes. Until we can figure all of this out, I am going to be keeping a close eye on you."

Izuku gulped.

Upon leaving the hospital, Midoriya finally got a look at his surroundings. He was in what seemed to be a bustling metropolis, but it was… different. Everything looked to be a strange fusion of modern and old architecture. 'I'm… definitely not in Japan.' His heart beat only quickened as he walked along with her. Nothing seemed right. Many people carried strange weapons and others seemed to be dressed rather old fashioned. He could have sworn several people had animal features! However, the most striking change he saw was in the very sky. Night had fallen and gave him a very clear view of the moon above, broken. "What the…"

Midoriya accompanied Goodwitch onto a medium-sized aircraft. The two were taken to a rather large building. The young hero was in awe at the sheer scope of the area. It dominated U.A.'s central building in size. "What… what is this place?"

"Beacon Academy. Someone here might be able to help." She stated.

The duo entered the colossal school and made their way up to the Headmaster's Office. Midoriya was in awe of the structure all the way. Goodwitch noted his amazement. It wasn't long before the duo made their way to the office. Inside, an older man sat at his desk, reading through several papers. Without looking up, he smiled. "Ah, Ms. Goodwitch. How can I help you today?"

"Professor Ozpin, while clearing the training grounds, I found this young man." She gestured to Midoriya. The young hero stepped forward, flustered, before bowing. "Uh, h-hello! My name is Izuku Midoriya."

Ozpin smiled. "It's very nice to meet you. I am Professor Ozpin." He held out his hand.

Midoriya smiled and shook it. "It's, ah, nice to meet you."

Ozpin smiled. "Mr. Midoriya, could you give me a moment with Ms. Goodwitch?" The young hero hesitated before nodding. He left the room, nerves beginning to set in. Ozpin looked at his comrade. "So, care to explain?" Goodwitch began to relay the day's events, from finding the injured Izuku to his strange ramblings in the hospital.

Ozpin listened intently before closing his eyes. "When I shook his hand, his aura felt… off."

"Off? What do you mean?"

"It's almost as if… the aura of several others is swirling around within. There's a huge reserve of power flowing inside of him."

Goodwitch remembered Izuku's words. 'So, he really did break his own limbs? What kind of monstrous power is that?'

Ozpin continued. "That's not all. His aura felt otherworldly. He's human, sure, but he's certainly not from here." He looked at the woman. "You said he spoke of strange places that don't exist?" She nodded. Ozpin thought for a moment before calling out. "Mr. Midoriya! Can you come back in?"

The greenette complied. "Is… is something wrong?"

"Perhaps… I might have a solution to this whole situation." He stood and walked to his window. "In all my years, I have heard many stories of heroes and monsters coming from other worlds. In some way or another, these tales have been passed down for generations, each being making their mark on our history, for better or for worse."

Goodwitch stepped back. "You… you can't possibly be saying…"

Ozpin looked at Midoriya, smiling. "Young Izuku, I think you might be the latest addition to these tales."

Midoriya felt his heart sink. "That's not possible…" He stepped back, processing things. Another world? How could he possibly be in another world!? Midoriya looked at his fist. 'When I used my power… did I throw myself into a new place?' Izuku gulped. "Is there a way to send me back? I need to get home! I need to know everyone is okay!"

Ozpin's smile faded as he looked out the window again. "I'm afraid… that's just not possible. Interdimensional travel is a tricky mystery to solve. Even if you were to simulate the events that brought you here, there's no telling where you'd end up."

Midoriya felt an immense despair take over. "I… I can't…" He fell to his knees.

Ozpin approached and placed a hand on his shoulder. "Izuku, I tend to find that certain things happen for a reason. We may not see it now, but maybe your arrival is just what the doctor ordered." He sat at his desk. "For now, however, we need to figure out what to do." He grinned. "Ms. Goodwitch, would you keep Mr. Midoriya under your care for a time? Teach him about how this world works and whatnot?"

Ms. Goodwitch was surprised. "Me? O-of course, Professor."

"Splendid. Izuku, while my colleague is catching you up on the ins and outs of our world, I shall get started on your registration."

Midoriya raised an eyebrow. "Registration?"

Ozpin smiled. "To Beacon Academy, of course!"

A/N: I've been interested in making a story like this for a while. There's many similarities between semblances and quirks, so I figured "What if?"
