Friendly Foreign Dimensional Exchange Student Spider-Man!: Academia
The U.S.J. Attack Begins!
"It's the Space Hero Thirteen, the pro heroine who rescues people in disasters across the world!"
"Woo! Thirteen is one of my favorite heroes!" Ochaco exclaimed.
"Come with me students, I can't wait to show you what's inside." They couldn't tell, but their teacher seemed to be smiling.
The students follow her and enter the building. Seeing the massive dome which looked to be larger than any sports stadium, it had quite an impressive exterior, but it's nothing compared to the inside. It's divided into six different sections, each one unique: a dome with fire artwork, a similar looking one with raindrops, a massive pool with a boat and slide, another being a hill emulating a landslide, and finally, a steep mountainous section to round it off.
"Holy crap, it's like some kind of amusement park." Eijiro describes what he's seeing.
While everyone is mesmerized by this incredible view of the facility's interior, Izuku flinches by the sound of a voice behind him.
"I am! I got some sleep, okay? I did!"
He turned around and saw Peter talking with Momo. The American teen looked exhausted, now that he cared to notice.
"Shipwreck, Landslide, Collapse, Mountain, Fire and Squall. A huge dome with six different Zones representing various weather or environmental hazards, I created this training facility to have students like you deal with these different types of disasters. I call it: The Unforeseen Simulation Joint, but you can call it U.S.J.!" Thirteen announces.
Which they, in return, immediately realized the similar naming initials of this facility and the Universal Studios Japan amusement park in Osaka. Aizawa walked closer to Thirteen.
"Hey, shouldn't All-Might be here already? Let me guess, he's in the middle of an interview." Aizawa wonder's in annoyance.
"Actually, it's something else. Apparently, he did too much hero work on the way to school this morning and used up all his power. He's currently resting in the teacher's lounge." Thirteen explains.
"That man is the height of irresponsibility… The clocks ticking, we should get started." Aizawa responds in annoyance again.
"Okay! First, I need to go over some points... one... two... maybe four… five?"
Thirteen held out her hand, starting with her first point.
"As some of you know, my Quirk is called Black Hole, it can suck in anything and turn it into dust."
"Yeah, you used that power to save people from all kinds of disasters before, haven't you?" Izuku asks her.
"Correct, but my quirk is also extremely dangerous… some of you may have powers that can kill. Everyone who has quirks, even civilians are certified and stringently regulated, since we must make sure no power is unsafe to society. Never forget that if you lose focus or make the wrong move, your powers can be deadly, even if you're trying to do something virtuous like saving someone."
Then some of the students and including Thirteen, hear Peter's voice behind them. Loud enough to be heard, but too quiet to understand.
"Is there something you'd like to share, Parker?" Thirteen asked.
Now everyone's eyes were on Parker. Bakugo scoffed in amusement, while Aizawa just flatly stared at him.
"N-Nothing. I'm alright, sorry for interrupting." Peter muttered, looking down and bowing lightly.
Thirteen notices that something is wrong with the American student. She will need to check on Parker before they begin the rescue exercises later.
"It's alright. Anyways, thanks to Aizawa's fitness test, you have some new knowledge about your quirk's potential. With All-Might's combat training, you experienced how dangerous your powers can be when used against other people and in different environments. Carry what you've learned before for today. You're going to learn how to use your quirks to save people's lives. No attacking enemies, not at each other, only to help. After all, being a hero is about ensuring the safety of others. That's all for me, thank you so much for listening." She finishes with a bow, getting applause from the students.
"All right then, class. First off-"
Aizawa abruptly stops speaking when everyone sees the lights have gone out in the dome. He looks behind, also noticing Parker is right next to him. Down in the central plaza, by the fountain, a black vortex appears as it spins and grows. A hand appears from it and grips on to the portal. Revealing to be a young man with unkempt, shaggy teal hair covered by what looked like severed human hands. Two golden lights appear from the black-purple mass above the figure as they stepped out. Aizawa knows that this is not part of the lessons, this is something perilous.
"Don't move and stay together! Thirteen! Protect the students!" Aizawa barks.
"What is this? I thought this was a rescue exercise?" Eijiro asked in confusion.
Then more menacing individuals slowly came out, all vaguely human, but no two alike. Some clutched weapons and others have body parts that areweapons.
"So, those scumbags used the press to sneak into the campus." Aizawa sneers.
Beside the hands-man, a massive black beaked titan walked out beside him. He wore nothing but cargo-pants, his brain exposed.
"The real heroes I see here are Thirteen and Eraserhead, but All-Might is not present." Explains the black-purple mist like figure.
The man covered in hands scratches at his neck. "Where is he? And I went through all the trouble of bringing so many friends who're eager to meet the great symbol of peace… they won't be happy that he's not here either. Maybe if we kill a few kids, he'll come out eventually."
"Kaminari!" Aizawa calls Denki, who perked up.
"Try using your quirk to either throw it off or call for help. I'm counting on you."
"R-Right!" Denki stammered nervously; he places his hand on the square-shaped earphone over his right ear.
"But sensei, you can't fight them alone! Even if you can nullify their quirks, you're fighting style is not suited for this. There's too many of them." Izuku yells at Aizawa.
"No hero is one-trick pony..." Aizawa mutters, surprising him.
"Go on with the students, Thirteen." he then says to her, which she nods in response.
Aizawa leaps out and attacks the villain mob, which surprises some of them, not knowing who he is. Two men and a woman try to attack from a distance, but he quickly initiates his power and nullifies the attack. As they stumble in sudden confusion, he coils his custom bandages around them and slams the two against each other, hard, hearing the crack as their skulls collide.
He lets them go as they fall to the ground. A few try to get the teacher in close combat, but he evades and counterattacks. The villains continue trying to fight back as Aizawa frequently nullifies their quirks dodging their attacks, and using his fists and the tape to take each of them down.
"Oh Eraserhead… so intimidating… so strong, and thanks to is goggles, you can't tell who's quirk he's erasing. Trying to make it hard for us to work together or rely on each other's powers. How annoying, the worst thing about dealing with pros is when they actually live up to all their hype." Exposits the teal haired man.
The students and Thirteen begin their escape. Momo stops, looking behind to see Izuku and Peter are still seeing Aizawa fighting all those villains.
"Woah… Aizawa's holding them off…" Izuku mutters in awe, as Momo convinces Peter that they should leave.
"Aizawa-sensei can handle himself. We need to go, Midoriya." She says to him.
The green-haired boy snapped out of his stupor, nodding in agreement.
"Something's coming!" Peter suddenly warns.
Izuku looks at him in confusion. Then hears a sound to look back at the front and see another black portal appeared in front of them as the black-purple miasma spewed out of the ground. It grew and spread with twin glowing golden eyes staring down at them, blocking the group's path.
"You won't escape from me, but where are my manners? Allow me to introduce ourselves, we are the League of Villains. My apologies for crashing into your little teaching session unannounced. We really wanted to say hello, see this famed training ground and have All Might take his last breath in this fitting place. Wouldn't you agree? Though I find myself deeply disappointed, your schedule we retrieved said that he was supposed to be here, but he's not. Either way, I still have a role to play." He huffs, spreading out its thick essence towards them.
Thirteen raises her hand, opening one of her metal-finger caps. Only to stop when Bakugo and Eijiro jumped forwards like madmen. Battle cries split the air, right before an explosion tore at the space around the black-purple mass.
"Did you think we were just gonna stand around and let you beat us?" Eijiro asks, his voice filled with confidence.
But as the smoke cleared, the black mass is still active. But then Izuku sees a line of webbing that hit something substantial inside the mass figure. It grunts in frustration, trying to pull away. Squinting his eyes, he opens wide-eyed to notice the metal brace appeared in the mass' neck, meaning it is the only solid object that the miasma figure has on him.
"Eijiro, Bakugo, go for the bracer! In the center!" Peter shouted at them.
"Nice eyes, Ace!" Eijiro shouted.
"Out of the way, meathead!" Bakugo screamed.
"Both of you get out of the way!" Thirteen ordered.
The two stopped their charge and glance back at the astronaut hero.
"Ah, as expected of UA." the mass complimented.
Then the living miasma exploded, spreading the dark mist and covering everyone.
"It seems the best way to deal with you lot is with my comrades. Prepare for your demise... now, begone!" he exclaims to them.
"Crap, what is this?!" asks the struggling Eijiro.
Mezo immediately grabs Mina and Hanta, they fall to the ground with his multiple spread-out arms covering them. Tenya, in a quick reaction, grabs hold of Ochaco and Rikido, taking them out of the dark smog. They look up and see it has turned into a half-shaped sphere blocking the view inside it. The others struggle to see from the dark purple thick mass blowing at them, a few screams as the mist begins to consume them.
"What's going on?!" asks the horrified Tenya.
"Don't know, but… that's one terrifying quirk…" Rikido worriedly responds to him.
Tenya looks behind the two classmates he saved.
"Uraraka, Sato, are you two alright?! Do you feel anything weird?" he asks them.
"First, yes, second no." Rikido answers.
"Yeah, I'm fine, nothing seems abnormal with me…" Ochaco also answers, touching her own body at the same time.
"Hey, look! The purple stuff is vanishing!"
Rikido's shout and his finger pointing turn Tenya and Ochaco's heads to see that as he said, the half shaped dark purple sphere slowly dissipating. Revealing Mezo, Hanta, and Mina still on the ground and Thirteen standing with her shoulders covering her large helmet. The four of them look around, able to see their surroundings.
"Students, is everyone okay?" Thirteen questions them.
"We're fine here." Replies Mezo from one of his mouth arms.
"Uh guys, aren't we missing some people?" asks the troubled Hanta looking around.
Of the twenty-one people who tried to escape the facility, there are now only seven who are present in the area.
"I-it can't be! Where's everyone?!" Mina asks in dread.
"Now, this will make things easier for me…"
The voice of the dark purple mist like individual catches everyone's attention as Tenya, Rikido, Mezo, and Hanta immediately get up to take their fighting stances close to Thirteen. While Mina and Ochaco get up slowly, looking at the villain who begins to change back to his previous form. The tendrils of miasma moving back and parts of the essence returning to the wielder.
"Shoji, use your extra ears and eyes to find the other students, they might still be here." Tenya commands him.
Mezo does so as he spreads four of his six arms behind him as two ears and two eyes are formed and start scanning the whole area.
"Shoji, found them? Anything? Where's everyone?" Tenya inquiries to him.
"They've been scattered across the facility, but our classmates are still here."
Mezo's response brings a sigh of relief to the six of them.
"What do we do? Physical attacks won't affect this guy and can apparently teleport stuff?" questions Hanta.
"Not only that, even if we now know there's something physical on his neck, he may also have ways to prevent us from getting our hands on it." Tenya chimed in.
"Class secretary." Thirteen calls to Tenya.
"Yes?"
"I have a job for you, run to the school and tell the faculty what's going in here."
This surprises him, not expecting Thirteen to give an order like this.
"It's most likely a villain is causing the alarms to not sound and making our phones and radios useless. Even though Eraserhead is canceling people's quirks, he can't find the culprit and were still completely sealed off from the outside world. Instead of waiting to find whoever's jamming everything, it will be faster for you to run and get help."
"Yes but, it will be disgraceful for me to leave you all behind." Tenya replies in protest.
"Go, Iida! They're keeping all of us trapped inside the U.S.J. because there might be lots of alarms outside and don't want us calling for help." Rikido moves forward and makes his fighting stance.
"As long as you can get outside, they can't follow, run away with your engine legs." Hanta goes in front and doing the same thing as Rikido.
"Use your quirk to save others, be a real hero!" demands Thirteen.
Mezo silently moves forward to help the other two, while Tenya looks in surprise at how no one does not disagree at all with their teacher's plan.
"I can help you out, just like I did when I floated you at the cafeteria, okay? No, prob!" Ochaco tells him.
"Please, Secretary, do it!" Mina pleads him.
"Even if this is your only option, are you really foolish enough to strategize in front of your enemy?!" the dark mist questions as he releases some tentacles to the group.
"It won't matter if you know what we're planning when I'm done with you!" Thirteen replies.
She reopens one of her finger metal caps and begins to suck the essence coming from the dark purple figure very quickly into her costume.
"Black Hole!" she shouts.
"Ah yes, the quirk that sucks up any matter and turns it to dust. But even with this astounding power, you're a hero who only saves people from disasters, Thirteen. That means you have little fighting experience or battlefield awareness!"
Instantly, the whole backside of her costume completely disintegrates, with bits of the material being sucked into the dark hole that opened behind her.
"How unfortunate you've turned yourself to dust." The dark mass comments.
"Another… warp gate…" Thirteen mutters in pain.
She collapses to the floor, the black hole sealing shut.
"I'm sorry… he got me…" she speaks towards the students.
"Thirteen!" Mina cries as the other students look in horror.
"Iida, get outta here! Go now!" Rikido shouts to him.
Immediately the engines in Tenya's legs fire up and begin his dash to the facility's entrance.
"Engine!"
Tenya runs past the dark miasma quickly.
"Nothing but a little sheep trying to escape from a giant wolf. If other heroes arrive, it will be harder for us to put an end to All-Might. So, I won't allow that!"
Right in front of Tenya, a third purple vortex appears, which spins and grows. He tries to break his run, but he does not have enough traction to completely stop getting inside the hole. Then Mezo jumps down and grabs hold of the dark warp with his multiple arms and lands on the ground with it.
"Run! I got him!" he shouts, Tenya immediately goes back to sprinting.
"You impertinent brats!" The black-purple mist stretches out his neck real long and catches up with the runaway student.
"You won't set foot outside those doors! Nobody will!" he barks.
No matter if the purple-dark mass begins to cover him, the tall student will not stop running until he reached that door to get help.

A dark purple vortex appears, which brings Mashirao and Yuga down, the long-tailed boy lands perfectly on to the ground, but the French boy fails the landing falling to the paved road face planting.
"Hey, are you alright?" Mashirao asks, kneeling beside him.
"Just… hope there's… no scar." He struggles to respond.
Both look around realizing they're no longer at the entrance, the fires burning most of the streets and buildings meant the two boys are now inside the Fire Zone of the facility.
"Look, there's two of them!"
Unfortunately, they are welcomed by a group of villains who seemed to have waited for someone to appear.
"Aoyama, use your laser." He whispers to his classmate.
The pretty blond boy nods in approval and immediately sets his personal firing stance: placing his hands on his hips and moves the waist backward. As the enemies are moving closer, he thrusts forward, releasing a few bright blue lasers beams hitting some of the foes while the others duck for cover.
"Now, let's go."
Mashirao dashes onwards with his long tail, grabbing a street light and spins to get more speed to go up higher in the air, while Yuga runs on the street following his classmate.
"Get back here, you brats!" shouts one of the villains with a black hooded jumper.
The group reach an intersection and see they have already lost the two teenage students.
"You twerps! You can't hide forever!" shouts one with thick, jagged hair.
"Spread out, if anyone sees one of them call out." instructs a giant bald, muscular woman.
All the villains split into small groups taking different directions of the burning city. Not realizing that Yuga is hiding underneath a parked car as he waits for all villains to move further away from him. Seeing that he is now alone, the French boy began to sneak from one building not covered in flames to another.
One group is of three men: one with a horn on his head holding a wooden club, one with bandages covering his face and chest, and the other with a mask covering his mouth with glasses and wielding two short swords. They slowly survey their surroundings when the horned man sights the long-tailed boy up in the air.
"There's one, get him!" he shouts to his allies.
The three see Mashirao, and he makes a run for it as the foes follow, reaching to the road he was at to find the kid got away again.
"Damn it, how can he get away so fast?" speaks the mouth covered one.
They reluctantly split up. As the man with the swords runs on one street, he gets hit by Mashirao, who lands an elbow to the villain's neck upside down as he is dangling onto a traffic light with his tail.
"I see him, up there!" shouts a woman.
Hearing he's been found, the long-tailed boy sees in front two people coming after him, a man with the jagged hair and the giant bald, muscular woman. But they are then struck by a bright blue laser beam coming out from a glassless window. The ray hits the left side of the man's chest with force, causing him to collide with the women pushing them to break through a large window of another building.
"Excellent shot Aoyama." He calls out to his classmate.
Instead of a response, Yuga comes out of the window but is panting and sweating. His stomach aches also kick in, and he groans in agony. Moving his shoulders to his tummy, now leaning on a building wall. He was quite lucky to reencounter Mashirao after they split up,
"Merde… merde…" he mutters.
The long-tailed boy lands on the ground and walks closer to him.
"Have you already reached your limit?" Mashirao asks him.
"Oui… I need time monemi."
Mashirao then climbs up a different pole and stands on it, using it as a vantage point to survey their current position.
"The sound of your laser may alert other villains of our location. I say we move on and see if we can find more of our classmates here. Can you still move?" he asks Yuga.
"Please let's be discrete, I'm rather powerless right now."
"Understood, let's go."
Both students start moving again with Mashirao jumping on the street poles and Yuga following him on the road.

Two students fall out of the dark purple hole that appeared on one of the streets in the Squall Zone, Fumikage, and Koji successfully land on the hard ground. The bird boy looks around, noticing they are not alone.
"Koda, get up, we have company." He tells his classmate.
Just as Koji got up, seven villains came and surrounded the two students.
"Alright, all together now, charge!" shouts one of them, the villains sprint forward to attack.
"Dark Shadow!" Fumikage commands, and instantly his bird-like monster comes out.
"Leave it to me!"
Dark shadow whirls around the two students, claws brandished slamming into those too close or too slow to duck a few managed to dive clear of the shadow beast's strike, granting Koda and Fumikage the room they needed to escape.
"Koda, run." he tells him and starts running.
"Augh, they're getting away!" shouts one of the villains.
They head into a narrow alleyway. After a minute of running in the passages of the tall buildings, they both stop to catch their breaths with Dark Shadow still floating close to his master. Koji then places his hand on Fumikage's shoulder and slowly shakes it, which the latter quickly reacts. Looking back to see his classmates is a little scared.
"Yes, what is it?" the birdman asks.
Koji opens his mouth but doesn't say anything, instead, he points upwards and shakes his head.
"Are you… scared of this place?" Fumikage questions.
But Koji shakes his head again, he then points behind them, pointing to himself and shakes his head with his finger aiming upwards.
"You… can't use your quirk in this zone?"
This next one makes Koji now signal with two thumbs up and an affirmative nod.
"Now that's a shame." Dark Shadow reacts to this exchange.
"I understand…" Fumikage responds.
"Hey, look!" a woman points to her left to see Koji is all alone in the alleyway, the birdman able to quickly move out of sight.
"We found you!" announces a man.
Both turn to the left and jump to attack Koji, but are then assaulted by Dark Shadow's large hand pushing them in full force to a building's wall which cracks, knocking the two villains out.
"And that's six of them down." Fumikage speaks, Koji offers a tremulous smile and a thumbs up.
"We're reducing their numbers, but very slowly, I hope it helps in the long run. Oh, and sorry, but I will be using you as bait for a while." Fumikage speaks to Koji with a hint of regret.
A smiling but nervous Koji reacts with a "okay" hand sign, not expecting to do much in their current situation anyway.
