A/N: Hello, everyone! This story was inspired by several YouTubers making Gacha Life videos of MHA characters (usually a handful of Pro Heroes) react to other anime characters as if they were family members of certain students in Class 1-A. They're good videos, but the reactions are few and far between, plus they mostly react to Tik-Toks where they have almost NO context. So, I thought I'd try it myself, but I don't have Gacha Life or any editing software, so I decided to write a fanfic instead!

Just be warned, this is a MASSIVE AU that changes a lot of things about the My Hero world and some characters may be somewhat OOC, due to having certain family members that made how they grew up VERY different from the original timeline. But still, I hope you all will enjoy this! Let's Begin!


Izuku Midoriya groaned as he opened his eyes with a bit of strain. It had been a normal day at UA high, the class had just got done with a rescue training exercise, when a portal suddenly opened in front of them. It was similar to Kurogiri in a way, but instead of an abyss of total darkness, this portal looked like it led out into the vastness of space, complete with countless stars and brilliant space clouds in all different colors. Still, knowing how deadly the vacuum of space is made these portals even less inviting than Kurogiri's. So the students tried to resist as the portal vacuumed them in, but despite their best efforts, they were all sucked into the portal, along with All Might, Eraser Head, Present Mic and Midnight.

And so, Midoriya now opened his eyes, feeling as if he had dropped onto something soft, but with many hard and rigid bits, as well as having something drop on his chest. And he opened his eyes to see two sizeable round mounds of flesh, covered by white fabric that covered these two orbs of flesh, with tiny teddy bears printed all over it. He also noticed that another layer of dark green fabric was above these flesh mounds, extending a bit past his head. After careful examination, he realized that the dark green fabric was similar to the pants and skirts worn by UA students. And since this was far more open than a pair of pants, that likely meant this was a skirt. And then it hit him: he was under the skirt of one of his female classmates, staring directly at her butt! And so, the boy did the only thing he could think of. Scream. "AAAAAAAAAAHHHHHH!" The green-haired boy cried out in absolute shock.

"Deku? What is it?" A familiar voice rang out as the owner of the ass in his face moved back and forth, eventually turning to look behind her, causing the skirt to move out of Midoriya's face, allowing him to make eye contact with Ochako Uraraka. After a moment of staring, Ochako finally realized what part of her body was directly in front of Midoriya's face and immediately began glowing red, completely eclipsing the normal blush covering her face. "Aaah!" She screamed, scrambling to move off of the boy and wound up tumbling down from wherever they were perched. "Oww... S-s-sorry ab-bout that, D-Deku..." She barely managed to stammer out.

"O-Oh, it's nothing! It wasn't your fault! Definitely not! No way!" Midoriya scrambled to say as well in a panic as he looked down at her. But as he looked down, he finally noticed by more grey and dark blue uniforms that he was on top of a pile made out of his classmates. "Oh, my gosh!" He cried out, leaping down next to Uraraka and turning towards his other classmates, waking them up and helping them out of their predicament, at which point they discovered their teachers in a pile under the first pile, with Aizawa and Midnight on top of it and in a similar position to what Midoriya and Uraraka were previously in.

The teachers slowly got to their feet, with Midnight and Aizawa desperately trying to act like they weren't in the situation they were in. "Where are we?" Aizawa demanded, in a tone that made it perfectly clear if a student brought up or joked about what happened, there would be SEVERE consequences.

"I-I don't know, sir. We just woke up and found ourselves on top of that dogpile." Midoriya said as they all finally looked around. They appeared to be in some kind of small theater, with a few rows of leather chairs with cup holders like one would see in the movies and a large stage in front of them, shrouded in darkness, the roof and floor below them pitch black, but with star-like dots all over to provide enough light for them to comfortably see, but not fully illuminate the room.

"Looks like we're at the theater. I could go for a nice movie with some popcorn. I heard they were making a one about UA teaming up with the Justice League!" Present Mic said. He was joking, of course, but he wanted to create some levity to the situation and keep the students calm.

"Don't be an idiot. We must have been taken by some villain." Aizawa said.

"Now, now. Let's not rush to any conclusions. And perhaps first we should see if we are able to make contact with UA or anywhere outside this place." All Might advised, trying to keep the situation calm.

"That's a good idea, All Might. Kaminari, can you make a connection?" Midnight asked the electric Quirk user.

"Right!" Kaminari said, putting a hand up to his ear device. However, after a moment, he let out a small growl of frustration. "Nothing." He confirmed.

"Sorry about that, but your electrical waves won't work outside of your own dimension." A voice declared as the stars on the floor and ceiling lit up brighter to fully illuminate the room. This lit up the stage and allowed them to see a woman sitting on a throne shaped like a hand with clawed fingertips. She then stood up and approached the crew.

In a similar fashion to the rest of the room, she looked as though she was composed of space itself, her body appearing to be made of glass the same color black as the night sky, with trails of purple and blue energy running through her body in various places, along with the familiar pink of cosmic clouds and several white and blue dots akin to stars speckled over her body. Her face was a lighter blue color and her eyes were pink. Her hair was long, reaching her waist with ease, starting black at the base of her head and continuing until it reached her shoulders, where it transitioned to purple. She appeared to be naked, the only thing that could be considered clothes on her body being a deep blue shawl around her arms and shoulders, also speckled with stars. Yet despite this, she didn't appear to have any... sensitive areas visible on her body.

"Are you the one who kidnapped us, you damn villain?!" Bakugo demanded, moving his arms behind him to blast forward towards this strange figure, only to find that nothing happened. "What the?" He asked, looking at his hands.

"Sorry, but I'm afraid that won't work. I've disabled your Quirks." She explained.

"Who are you? And what do you want with us?" Aizawa demanded, getting in front of the students along with the other Pro's to shield them from the potential threat.

"I am the Celestial Empress who observes and controls the universe. My true name is impossible for you humans to properly pronounce, so instead, you may call me Sandra. As for what I want with you, I can assure you, I mean you no harm." She explained.

"Really? Because kidnapping us seems pretty harmful!" Kirishima snapped.

"Especially with how some of us landed." Midnight agreed, a slight blush coming to her face as she remembered her butt being in Aizawa's face.

"You have my apologies. This is the first time I've attempted bringing mortals to my sanctum. I have not gotten the fine details down yet." Sandra explained.

"Right. I'm sure we all just fell in the exact order we did and in the exact positions..." Aizawa said in annoyance.

"It... could happen." All Might said uncertainly, just hoping to avoid conflict.

"So, what did you bring us here for, then? If you wanted to take us to the movies, we probably would've said yes. The kids are due for a vacation." Present Mic said.

"Yes, well... If I had attempted that, I think some of you would've tried to prevent me from showing what I planned to show you." The cosmic being told them.

"And what would that be, exactly? As the class representative, I'd have to insist you not show us anything inappropriate." Iida said, doing his usual robotic chopping.

"Well, you all in Class 1-A have grown quite close over your time together, correct? You could almost say that you've become like family?" Sandra asked.

The students then looked between each other, uncertain of what to say. But finally, Yaoyorozu stepped up. "I can't speak for all of us, but I would most certainly consider you all family after what we've been through as a class." She admitted.

Tokoyami then nodded. "Indeed. Though we may not be blood, the bond we've made together has endured and strengthened over time, being tested and reaffirmed through our many encounters with the League of villains has made us as close as any family could hope to be." The bird-headed boy added.

A mass of darkness then emerged from Tokoyami's back. "Yeah! We're all brothers and sisters in arms!" Dark Shadow declared.

"Yeah! We've got each other's backs for life! Just like any family would do!" Hagakure cheered, her clothes rising and falling in place, indicating the invisible girl was jumping up and down.

Slowly but surely, the rest of the class slowly began to voice similar feelings for each other. With one exception... "Hell no! These extras are just lucky enough to be my groupies!" Bakugo snapped.

However, he was quickly grabbed and pulled into a group hug by the Bakusquad. "Oh, come on, Bakubro! You know you love us!" Kirishima said.

Bakugo growled at this, before huffing and looking to the side. "I tolerate you." He admitted.

Sandra smiled at this. "How lovely. Still, I'm sure there are some things you don't know about each other. And each other's families." She explained.

The class took a moment to consider that. "We never thought to ask each other anything super personal, like about family stuff." Jiro admitted.

"Well, now, you don't have to. Because I'm going to show you! Things you never knew about each other! Like for instance, did you all know Bakugo has a sister?" The celestial asked.

The class then turned to the explosive Pomeranian. "You have a sister, Bakugo?" Kirishima asked in surprise, before smirking. "Is she hot?" He asked.

Bakugo actually seemed nervous when the mention of him having siblings was brought up, but soon growled at Kaminari's second question. "Shut the hell up! No I don't! I don't know what this space bitch is talking about!" Bakugo snapped.

All eyes then turned to Deku. "Midoriya?" Tsuyu questioned, hoping along with the others that they could get some answers from Bakugo's childhood friend.

Midoriya shook nervously, before caving into peer pressure. "He-he has two sisters. And a brother. One older sister and brother, who are twins, then an older twin sister." Midoriya finally admitted.

"Two sets of twins? Your poor mother." Midnight said sympathetically.

"Aww, then that makes you the baby of the family, Bakugo!" Ashido cooed, leaning against the explosive boy.

"Can a baby kick your ass, Raccoon Eyes?!" He snapped.

"Well, now that the cat's out of the bag, I'm going to show you the siblings you were never told about. And even some you yourselves never knew about!" Sandra said, snapping her fingers, resulting in all the students and teachers being placed in the middle three rows of the theater. "If you want any snacks, just think of something and it will appear. Now get comfortable and get ready to witness the queen of black air force energy. Bakugo's big sister, Revy." Sandra declared, causing her throne to appear in the back of the room, no longer blocking the view as a theater-like screen started to life.


A/N: Well, that's the introduction done. I hope you like it and are looking forward to more in the future! I plan to show them a mix of actual scenes from the universe of the character in question, but also the occasional YouTube video. I know I said I complained about the Gacha videos watching Tik-Toks, but the videos I have in mind are ones that actually give a decent summary, if not full context for the situation, or even the full series in the case of the first video I plan to show them, as well as just being funnier, in my opinion.

So, a few things to note about this AU: Earth is quite a bit larger and there are more countries throughout the world, as well as parts of the world that are unknown to the characters, even the most well-researched of Pro Heroes. And things like aliens and demons are known and documented in this universe, as well as Stands from JoJo, as well as Weapons and Meisters from Soul Eater, though these abilities are just believed to be forms of Quirks. However, certain things are still unknown, or at least not common knowledge, like Devil Fruits, Kishins and Kishin Eggs, Hollows and Teigus, so some people are in for surprises later on when they see some of the things their families do.

I have a handful of ideas for family members certain characters might have, but I am open to suggestions. You may come up with things I hadn't even considered. The teachers are fair game, too! Todoroki may have been onto something about that secret love child thing! Or if we should go back to a certain character later on down the road to show them a certain scene you think they should see. So be sure to let me know in the reviews! Just don't go TOO crazy, okay? Like saying Frieza is Mina's brother or something. I know the MHA world is crazy, but that is too much of a stretch.

But this is all for now. Until next time, stay happy and healthy!
