Before I start: English is not my first language so don't be surprised if my grammar is a little weird and feel free to correct any mistakes.
This takes place between the Pro Hero Arc and the Joint Training Arc, I originally wanted it to be set between the Final Exam Arc and the Forest Traning Camp Arc, but this gives me more freedom. Read this fully expecting characters to be OOC.
Izuku wakes up in an unfamiliar room, the walls, floor, ceiling and even the furniture were pure white. "Was I kidnapped?" Is the first thing that comes to his mind, but it didn't make sense since he wasn't gagged or tied up. He investigated the room, the only furniture besides the bed was a simple desk and the only things inside it were a blank notebook and a pen, he took them and decided to go out.
The rest of the building looked just as weird and uncomfortable as the room he woke up into, the corridors were also white and the other rooms were locked, he kept walking until he heard noises, he followed the noises and found the rest of his class with Aizawa and All Might in a room with couches, chairs and a large screen, Aizawa noticed his presence and walked towards him.
"Midoriya, are you okay? Do you remember how you got here?" Asked his teacher.
"I'm fine but I don't know how I got here, why are we here? Were we kidnapped?" Midoriya started to mutter.
"STOP FUCKING MUTTERING DEKU." Screamed you know who.
"Calm down everyone, I'm sure that there is a completely reasonable explanation for this." Says All Might trying to calm them down
"Interesting, our kidnapper must have a very skillful team to take so many people at once." Says Nezu, entering the room being followed by Midnight, Present Mic, Hitoshi Shinso, Mei Hatsume and...
"MOM!" Screams Izuku, running towards his mother and hugging her, wondering why someone would abduct her.
"Izuku! Are you okay?" Asks Inko, relieved as her son confirms his well being.
The students and teachers go back to talking among themselves, trying to figure out how and why they were abducted, when a small floating robot enters the room.
"All subjects presence confirmed, please sit down." Says the small robot in a synthetic voice. Hatsume was drooling.
"What a fascinating little thing! Are you our kidnapper?." Asks Nezu, examining the small robot.
"Correct, I am called 536 Compassionate Guardian, you may call me Guardian. I transported all of you here as instructed by my masters, they decided that multiversal observation was the most efficient way of assuring that the savior is mentally and emotionally stable to face future adversities."
"May I ask who your masters are? And what do you mean by 'multiversal observation'?" Asks Nezu in an upbeat but firm voice.
"My masters are called The Old Gods, they observe the different universes and rarely get directly involved, but they decided that your universe savior is ill suited to his future task, choosing to intervene by summoning him and people they judge important to observe different versions of himself, with the objective of accelerating his growth artificially. Multiversal observation is the act of observing different dimensions, consider yourselves privileged as no mortal ever had the opportunity of watching the multiverse."
"And who is this 'savior' you keep talking about? Is he between us?" Asks Aizawa.
"Izuku Midoriya." Guardian answers simply
"W-w-what do you mean? Savior?" Asks Izuku confused.
"BULLSHIT!" Screams Bakugo "Why the fuck is he so important?" he asks himself.
"Every universe has someone destined to do great things. Your destiny is to defeat your universe's incarnation of evil, that is the reason you were designed the title of 'savior'." Explains Guardian "any other question or I can initiate the multiversal viewing?"
"How are we going to do this...observation?" Asks Todoroki, curious to see different versions of his friend.
"I am sure that everyone noticed the screen, the universes will be shown in what you know as 'movies' or 'series'. It was decided that this is the best way of ensuring your mortal minds can comprehend what you will see"
"Will we have snacks?" Asks Ashido.
"It would be illogical, while in this dimension you will not have mortal needs, no need for nourishment, hydration or sleep." Guardian answers.
"That's nice but eating while watching helps you stay focused." Says Kaminari, trying to bullshit the machine.
Before the robot can answer, a table with many snacks and drinks appears in the room. "It seems like my masters saw logic in your argument, I will not argue." Says Guardian defeated. "When everyone is organized, I will explain the rules and then start the viewing, feel free to get comfortable but make haste."
"Deku-Kun, it looks like you're going to be a really important guy.'' Says Uraraka as Iida, the Midoriyas and herself sit in one of the couches, with Todoroki in an armchair by their side.
"Indeed! I can't help but feel a little jealous." says Iida with a smile, proud of knowing that his friend will be so important in the future.
"Midoriya-san, it's a pleasure to meet you. I'm sorry for being too straightforward but I have to ask this: Is Izuku All Might's secret love child?" Asks Todoroki.
"TODOROKI, NO!" Screams Izuku.
"TODOROKI, YES!" He screams back.
"Izuku, you sure have some interesting friends. Todoroki-kun, was it? Sorry to disappoint but Izuku's father is my husband who is currently working overseas."
"That's what I always tell him! He just says 'there's no way you can know that for sure', even if me and dad look the same! I showed him a picture!" Says Izuku.
"As I said: There is no way you can know that for sure. Midoriya-san, are you absolutely sure? Maybe All Might was disguised."
"Yes Todoroki-Kun, I'm absolutely sure that All Might is not Izuku's father."
Todoroki narrows his eyes in doubt, but nods. He will just get the truth in another way. All Might hears the talk and suddenly the ceiling starts to look very interesting to him,
"I think we're good now. Guardian, you can start the multiversal thing." Says Aizawa drinking a beer, he can't handle this sober.
"All right, the rules are simple: While you are in this room, time will not pass in your world, after ending this, you will be transported to the morning after your disappearance, as if nothing had happened. After returning to your world, you will be able to discuss what you saw with the people in this room but not with others. While in this room, fighting between yourselves is not allowed. If more than 4 people are not paying attention, the video will pause and resume once everyone is looking at the screen. The universes shown will be selected randomly, when a universe is selected I will be able to give a little context before the video starts. The rules are few and simple but important and they will not be broken, do we have an agreement?"
"Yes, you may start, Guardian-San." Says All Might, wanting to see what other universes hold for his apprentice.
Guardian's orange eye shines brightly as the screen turns on, it starts to show many images too quickly to be seen, before going dark. A single phrase appears on the screen.
"Dark Souls...it sounds a little dark." Says Kirishima as Tokoyami smiles.
