Izuku looked around, surprised. He had not expected of landing in London, the capital of the United Kingdom. He stopped a second, as a sudden thought hit him. "Isaac, does the name JUK have to do with the fact we are in the United Kingdom?"

"Correct. JUK means One for All was born in Japan and is currently in the United Kingdom. JUS that the Quirk is currently in the States, held by yours truly. It's a simple code, but it helps us divide the universes easily. Other questions?"

Itsumi looked up and down the Tames, before turning around. "Where is the London Eye?" She asked, "We should be near it if I'm right…"

"Weird question, but I can answer. There never was a London Eye in this world. Ferry wheels are pretty much useless."

"Why?" Ojiro asked.

"For the same reason we chose the Allforverse as our base, I think. Not that I can be sure, I never tried to do a research on that. Now follow me, I will show you the League's base." He replied, and they turned. The building in front of them was a classic European building, one that looked exactly like how Izuku would picture a large building in old London. "You know, there is a fast-food restaurant here in my universe." Isaac mused as he opened the door with a key, and everyone followed him inside.

The place was… different than what Izuku had expected. He was imagining a place like Isaac's Star Tower, but this was a lot more unassuming. It was similar in shape, with light entering from the windows in a normal-looking reception with a large desk, but it lacked most decorations that Isaac had put up in his office. The woman behind the desk, a brown-haired, polite looking individual in her fifties, wearing a pair of reading glasses and typing calmly on a computer, was completely normal, except for one fact. He recognized her.

"Uraraka?" She asked out loud before he could stop himself. Isaac smirked.

"Correct." He confirmed, "Good morning, Ocha."

"Morning Isaac." The woman winked at him, before glancing at the four, "I take you found some more guests?"

"In a way, but we also have a genuine Wanderer that needs more training. How are Beta and Delta?" The man replied.

"You should ask about Mariah before worrying about those two."

Isaac grimaced, "Can we talk about this later?"

"I was asked to inform her about your arrival. And don't ask me to delay that," She added when he made to reply, "You know Izzzuku is probably telling her as well."

"You are unfortunately right, but for once I want to see her too. Send this down to the labs. I think Mariah and the wizard will want to take a look at it." He replied, putting a small envelope on the table. Uraraka nodded, putting it away. "Where is Beta, by the way?"

"Right here sir." A voice calmly replied to their left. They all gasped when they noticed the green hologram standing to their left, and it took them a moment to realize they were looking at Zuzu-9, because of how different the hologram was.

She seemed to be in her late teens or very early twenties. Her hair was kept in a ponytail that reached the mid of her back, and she was wearing a pair of small glasses of all things. In her hands was a tablet, which Izuku had to assume was just for show. The suit she was wearing gave her a more professional appearance. When she noticed their startled expression, she smiled softly. "Pardon me. I seem to have scared you."

"Of course you scared them." Uraraka replied, "Didn't I tell you it's more polite to appear a distance away from the person you are talking to?"

Zuzu-9 nodded, before turning once more to them. "My name is Zuzu-9-Beta, the AI in charge of the surface levels of the League for All Headquarters. You can address me as Zuzu-9, Zuzu or Beta. Please do not use the name Zu, I find it demeaning, or names from 'pop culture'. Mister Izuku Midoriya called me Living Brain once, and I'd rather not be compared to a villain."

"Sure. We know Zuzu-9-Gamma, you know that right?" Ojiro asked.

"That is not important. While we derive from a common copy of a twelve years old Zuzu-9-Alfa, our upbringing has made us different AI. I would suggest you don't consider us just a mere copy of each other." The woman turned to Isaac, who had just been observing them, "Mister Isaac, I have been told to inform Miss Mariah of your arrival. She will be here in about an hour."

"Thank you, Zuzu." Isaac growled, Uraraka barely holding back her laughter. "Now, while I wait for her, I need to register them and give them a tour. Ochaco?"

"Sure. So, we have a Shoto Todoroki, that's a nice change. Ojiro Mashirao, that's a first. What's your name dear?" She asked, pointing at Itsumi, while typing on her computer.

"I'm Itsumi Midoriya." She replied. The woman raised an eyebrow.

"Sorry if I ask, are you the daughter of an Izuku and a Katsuki?"

"My mother is called Katsumi." Itsumi replied, while Izuku noticed Isaac make signs to stop the line of questioning. Uraraka seemed to figure it out and lightly gasped.

"Oh, sorry for the question dear." She replied, while writing her name down, before turning to Izuku and groaning out loud. "Another Izuku?"

"We have a lot? I didn't notice." Isaac replied with a grin. "His Hero name is Deku and his home universe is J-082. He is the Wanderer, by the way."

"We have four Izuku right now, I swear if you bring me another one I will have to start writing down their age too."

"Would that help with the Green Scar?" Isaac replied, as Izuku raised an eyebrow. "Also, four? I thought…"

"We have a new Wanderer and Spider-Man came around."

"I wasn't informed of another Wanderer." Isaac replied, turning to Zuzu.

"According to the League's Founding Chart, any Wanderer that appears in JUK-016 is under miss Mariah's jurisdiction, sir. She decided this Izuku was safe to bring to the Headquarters, especially because he was trying to hand his version of Kurogiri to the Police. It all happened two days ago." The AI explanation made Isaac frown slightly, but after a moment the man just shrugged.

"Oh well, fair is fair I suppose. Send me his file though, I want to take a look at it. And I do want to meet him. Where is he?"

Zuzu-9 closed her eyes a moment before opening them again. "He is currently resting in his room. Judging by his two previous sleeping schedules, I expect him to wake up soon."

"Tell me when he does." Isaac replied, before stopping, "She didn't try to induct him in the Initiative already, correct?"

"As per the accord you two signed, you would have to be informed first and be allowed to give your Veto. Moreover, she asked me to tell you to 'have a little faith, the Initiative is not for Wanderers that can't go home.' If you asked that question."

The Hero sighed, "You are right, sorry."

"I personally don't think it was wrong to ask, sir. In any case, I believe you wanted to give a tour to our new guests. Should I inform Delta?"

"Sure, but I would start with the upper floors."

"Understood." The AI bowed slightly before disappearing. Izuku still had a hard time wrapping his head around it, but he heard a chuckle and turned to the older woman. Uraraka winked.

"I get it dear. The League is a crazy place, especially for you. I should know, I was a founding member." She moved her hand under her desk and took out a small bowl of candies. "A candy?"

Izuku hesitated a moment before taking one. It was sweet, almost excessively so, but he felt like he would need the sugar. "If I might ask… Are you a One for All user?"

"In a way." She replied calmly, "At my peak, I was known as Infinity Woman, the Orbital Hero. That was almost thirty years ago. Right now, I'm just a One for All user with a ruined back."

Izuku blinked, before he realized what she meant. "I'm sorry to hear that."

"Don't worry, dear. Have a good day."

Izuku nodded and followed Isaac, Todoroki and Ojiro, with Itsumi to her side. They made their way up the stairs, to the first floor. As they did, Isaac stared intently at his phone, nodding as he read what Izuku assumed was the file on the other Wanderer.

This part of the building seemed to be a large cafeteria. It reminded Izuku of UA's, although it wasn't as large and there wasn't Lunch Rush behind the counter. Instead, it seemed automated, and it didn't take much of a guess to figure out it was Zuzu-9's doing. Sitting at a nearby table, though, were three figures that made Izuku's eyes widen.

A tall, muscular man with ash blond hair, red eyes and a smile on his face was observing a man with green hair and eyes, that appeared to be in his mid-forties argue with a second one, that could have been mistaken for his son given their resemblance, especially because of the apparent age gap that seemed to place the latter in his early twenties. The latter seemed well built, but the former had a body Izuku associated immediately with Izo, muscles bulging under the low-cut black and green shirt he was wearing.

"… It's not just a magic item you can cram in a portal machine and hope it works. Those scissors open dimensional rifts. Even without considering the risks of toying with magic one of the oldest entities in the known universe- in my universe created, you are not even sure it would work." The older man was explaining, looking at the youngest.

"I know, but look at it this way. If you use magitech portals built to traverse the Multiverse and combine them with magical portals built to move through the dimensions of your own world, wouldn't that likely take you back home?"

"Or it could open a portal in this universe to some madness dimension. Spidey, you have some science knowledge, but magic? Your universe is dry on that. Besides, the point is moot. My scissors are back home."

Bakugou – because that was Bakugou, Izuku realized – coughed, his red eyes moving to Isaac, "Well this was fascinating, but Isaac is the perfect distraction to make you two stop arguing, so I'll take it." He said, pointing to him. The other two looked their way, and Izuku coughed awkwardly, unsure of what to say or do.

Two more Izukus. 'This is bound to get confusing fast.' He thought, thanking the fact that so far all of them seemed to be at a different age.

"Isaac." The younger one, the Izuku they had called Spidey, said, standing up. Izuku noticed his suit, a green superhero outfit with a white spider.

"Spider-Man, how are you doing?" Isaac asked in perfect Japanese, fist-bumping him, "I thought you were supposed to be around next week."

"I have an issue. The Prowler vanished, so I decided to come and pay a visit in advance. I got Mirio to give me a lift over here, though I will need a ride home."

Isaac quirked an eyebrow, frowning, "Isn't it jumping the gun a bit to suppose she is in the Multiverse? I was under the impression the Prowler had already gone quiet for a few years."

"We have a camera feed showing her driving late at night on that monstrosity of her motorcycle just to vanish out of existence at a red light. And I mean vanish as in blink and she is gone. There are no registered Quirks that can do that, and she would have rather killed All for One than gotten separated from her bike." He sighed, "We also found out who she was. Not hard to put two and two together."

Isaac looked sympathetic, "Someone you know?"

"You could say that. Anyway, any idea?"

"I'll pass the word around and will check any report we have received recently. You are free to do it too."

Izuku glanced at the others. Surprisingly, he was the only one showing any reaction to the fact an alternate version of himself was a Spider-Man, so he spoke up. "Uh… You are… You are Spider-Man, right? The genuine thing?"

The man in the green suit turned around and chuckled, "Yep, spider bite and all. Nice to know people have heard of me. Although, I bet you actually know Peter Parker."

"That's… Wow. There is an alternate me that is Spider-Man." Izuku would have never said to have been the biggest comic books reader, and when he did buy some, he usually would buy the All Might ones, since they were… well, realistic. Yet, even he knew who Spider-Man was, even after all those centuries since he had debuted.

"Who?" Ojiro suddenly asked. Izuku stared at him in disbelief before turning to Todoroki.

"Yeah, I don't know him either. Someone you know Izu?" Todoroki asked.

"Y-You guys don't know Spider-Man?"

"Never heard of him."

"Nope."

Izuku turned to Itsumi as a last resort, who frowned "Never heard of him. I think there is an American comic book Hero called The Scarlet Spider? Shiro is a big fan, and so is Uncle Sero." She shrugged, "Why, is that important?"

"Important? He is Spider-Man! One of the most famous Marvel Comics superhero!" He pointed at him, but then turned noticing the entire table laughing.

Once they stopped, the man that had accompanied them just shook his head. "The Multiverse is fun like that. You jump one world, and a fictional work that was a commercial success is a commercial flop that is never brought up again." Isaac explained.

The other Izuku, the one sitting at the table, interjected with a nod, "Yes, pop culture is just unpredictable from what I've seen. Never assume someone has seen Star Wars until they confirm it."

Todoroki raised an eyebrow, "Star Wars?"

The older man chuckled. When he moved to face them, his low-cut shirt showed part of his chest, and what seemed a… Butterfly tattoo? Izuku wasn't sure if it was a tattoo or a scar, since it looked too perfect to be the latter but too pale to be the former. "Case in point. Nice to meet you, by the way. We are called Izuku too, but you can just call me the Green Scar and him Spider-Man. Or Spidey. The embodiment of silent treatment over there is Bakugou, and there aren't other around here so for now just call him that, he might even answer." He added pointing to the blonde man, who just grunted, "What's your Hero Name?"

Izuku shook his hand, feeling the firm grip of his muscular arm, "It's Deku."

The Green Scar nodded with a smile. "Same here, but you can keep it. Unfortunately, I have my back-up to turn to."

"This is my worst nightmare…" Todoroki mumbled, not low enough for Izuku to miss it, passing a hand over his face. "And there are two more?"

Isaac clapped his hands together, stopping Izuku before he could ask what the older version of him meant. "Anyway, this is nice and all, but I need to show them the rest of the facility and explain the training he will have to take. Izuku…" He stopped when the three of them turned to him, shaking his head with an amused smile on his face, "'Green Scar', any idea where Mel is?"

The man scratched his chin, the stubble of green beard grating against his fingers, "Last I saw her, she was going down to the underground levels. She wanted to check on the Kurogiri the new arrival brought in."

"That does sound like her. Thank you."

The man nodded and Isaac gestured for them to follow him. Izuku nodded, even as he didn't actually look away from the table until they were on the stairs.

"Quite the experience, uh?" Ojiro asked.

"I can't believe I still get amazed by it, and yet…"

"And yet every time is like the first." Isaac replied, showing them the floor above, even if he did not stop. "The second and third floors are apartments. They are meant for Wanderers that need to live here, like the Green Scar or Uraraka." He explained, "Currently there are four… no, five rooms in use, I forgot the new arrival. Who would be on this floor…" He stopped as they heard steps coming down from the floor above. As they looked up, they saw a young woman with blonde hair walk down the stairs, accompanied by yet another Izuku. This one, though, seemed to be about the same age of Deku, with slightly longer hair and a slightly less muscular physique marking the most notable differences. Aside from that, they could have been twins.

"… And don't worry about Katsuki, he is all bark and no bite. No, scratch that, he doesn't even bark to be honest, he mostly glares." Melissa was saying to the nodding teenager. The two groups stopped when they noticed each other. Deku noticed the other Izuku's eyes going wide when he saw Isaac and could have sworn they were about to pop out of their orbits when they moved to him. Melissa, on the other hand, just smiled. "Hi! Isaac, you never told me there were new guests."

"Sorry, Lissa. They arrived two nights ago in my own universe and I had to also deal with the other Wanderer. It slipped my mind."

"No problem, no problem. I was showing Dekiru here the place."

The other Izuku, the one called Dekiru, nodded. "I-it's a pleasure to meet you, mister Isaac."

"Thank you, but there is no need to be so formal. So, I read your report. Interesting Quirk you have, Fusion. Mind explaining it?"

Dekiru nodded. "Yes. I can fuse with various materials by absorbing them. Any solid is a go. I can also fuse with people, but…"

"Yes, the report does mention you don't seem to like it as much, so don't worry. Still, that is an interesting Quirk you have."

Izuku quirked an eyebrow, surprised. "Isn't it weird his Quirk doesn't relate to mom and dad? I mean, unless it does and they have different Quirks compared to my world." He quickly added, looking at the Dekiru.

"No it's alright, I have a rare mutation."

"Correct." Isaac nodded, "Though it's not really rare for you. For some reason, in Quirked universes it's very rare for Izuku Midoriya to inherit his parent's Quirk or a combination of both parents'. Instead, the usual results are Quirklessness or a random mutation. It's a very interesting phenomenon, some sort of Multiverse-wide common event with few outliers…"

"Ahem, Isaac, rambling." Lissa pointed out. Isaac stopped a moment.

"Right. Sorry. I can talk at length about the Multiverse. Anyway, I'm sure we can get you back home. We have a few methods to try and figure out the position of unknown Universes." He explained, and Dekiru lighted up at that.

"Thank you, sir."

"Don't mention it." Isaac replied, and Izuku recognized the pose with a thumb up and the large, shining-white smile as All Might's own. He had noticed before, but of all the other versions of himself he had met, Isaac was the closest to be someone you could call a All Might copycat. He reminded him of Mirio when it came to his heroic side. "Now, if you will excuse me, I have to finish showing them the place. I assume Lissa already did the same."

"Y-Yes."

"Excellent." Isaac nodded and started walking up the stairs. Deku and Dekiru exchanged a single glance before they left in opposite directions. For some reason, Deku felt like they were thinking the same thing.

Their situation was really absurd.

-x-

Itsumi had a lot of things in her mind when she reached the top floor, and Isaac's explanation on what kind of role each floor served was lost. Even when he mentioned he kept the upper floor for the League's training facilities, she barely paid attention, instead thinking of what she had seen so far.

Katsuki Bakugo – she knew his name since Izuku had explained him what her mother's male equivalent was called – seemed vicious, but he hadn't said anything to her or anyone else. 'You'd think he would be curious about someone that might as well be his daughter.' She thought, sighing.

"Are you ok Itsumi?" Izuku asked, next to her.

"Yeah, it's just… I was wondering who of them would want to help us." Itsumi replied.

She watched Izuku suddenly freeze and stared at him a moment before her eyes turned into slits. "You forgot?"

"No, no, of course not, is just… I've never met so many versions of myself and my friends at once. I don't know how to react, so my mind focuses on observing them. I just… I don't know what to do. Do I just ask them if they want to come and save my own Universe?"

Itsumi had to begrudgingly agree. She had not asked anything because she had the same issue: she didn't know how to ask someone for help in a matter like this. 'Hello, do you want to come with me and risk your life to fight a mortal threat that however doesn't put your universe into danger?' That wasn't really the best pitch.

Izuku had clearly noticed her expression, since he put a hand on her shoulder and smiled. "We can do this, don't worry. Maybe we can get to know them better first. At least me and that Dekiru shouldn't be terribly different."

"You think he will help us?"

"If he is like me, he might. Although, he was born with a Quirk, so maybe his upbringing was different? That plays a role, I suppose."

Itsumi could see Izuku's brain gears starting to spin, or so she had come to read that expression he was making. It was fun in a way. Her father was a different person, but she could still see parts of him in Izuku. She had a second to realize thinking of her family had been a bad idea, as all her worries rushed to her mind. She shook her head to stop herself from thinking and looked up to Isaac, who had just finished explaining something she hadn't really caught, before he pointed to an elevator.

"From here, we will go downstairs to the underground floors." He explained, pressing a button. The elevator started coming up… No, was already coming up before, Itsumi realized, suddenly curious. With a loud beep, the elevator doors opened and Isaac froze.

The woman that walked out was not what Itsumi had expected. Wearing an elegant suit that looked very similar to the one the Zuzu-9 hologram had donned before, with the difference this one was a dark tone of grey, the woman was a little taller than Itsumi. Her hair was bright green, and after a second Itsumi realized she didn't have hair but thorny vines, that she kept tied in a bun on top of her head. Her eyes were green, a darker shade than her hairs. Her freckles did nothing to make her less intimidating as she speed walked towards Isaac.

"Isaac…" She said, stopping in front of him. Her bun of thorny vines left her still half a head shorter than Isaac, but she didn't seem to care as she stared straight in his eyes, "You know, the leader of the League for All is supposed to actually be present when we schedule a meeting."

"I'm sorry, I know, but I have a good reason."

"Oh? Do tell. Was it by any chance that you have finally decided to compile a list of candidates for the Initiative so I can skip the process of passing through to you every single one for your Veto? Or is it that you were uncovering some big event in the Multiverse that might affect the outside world?"

Isaac pointed to Itsumi and the rest of the group, "I had guests, Mariah."

"That is hardly a problem for you. We set up the headquarters in my universe because you can Teleport here with minimal trouble. We schedule the meetings so they don't interfere with your other duties. And then, just because a few people that, I am sure, could have waited a single night, show up at your doorstep, you suddenly think you can skip your duty as the League's leader?"

Isaac took the hit, Itsumi noticed. "Now, Mariah, I don't think this is appropriate. We have new guests, some of which will have to stay here." He frowned before continuing, "And will probably be interested in your Initiative."

Mariah raised an eyebrow, with an expression Itsumi recognized as curiosity, as she moved her eyes to look at them. She seemed to be watching through them with those eyes, scanning them for any defect she might notice before she turned to the American Pro Hero. "One Quirkless, a Todoroki and two One for All users. Three of them have used magic before too. That is… oddly generous for you."

"Give a read to the report." Isaac said, and her phone beeped. She opened it, and Itsumi could see her opening some text file. "For once, I will probably have to authorize you to take some steps towards the Initiative."

"I told you before this would happen sooner or later." She replied with a smug expression, before sighing, "You are an headache and a half, Star Might. Make sure you show up in time for tomorrow's meeting or I will show you what I can do with my Quirks." She turned around, smiling at the group, her eyes fixing a moment on Izuku. "Well, what are you five waiting for? Get in the elevator, if you want to see the underground floors."

Her tone left them no room to respond as they moved in. The elevator was large enough to fit all six comfortably and leave extra space, but Itsumi still felt tense. She had been like that since Mariah had showed up, a sensation of danger in the back of her mind, like she was in the same room with a poisonous snake.

Izuku clearly felt the same, because he spoke to her. "Miss… Mariah?"

"Yes?" She asked.

"Uhm, if I may ask, who are you?" He asked.

"Oh, where are my manners. My name is Mariah Midoriya. I guess I am your grand-daughter, though it's more accurate to say you are an alternate version of my grandfather." She extended her hand, and Itsumi did catch Izuku's hesitation at grabbing it. He defeated it a moment later, but shook it quickly and let go a moment later.

"Uh, that makes me your aunt I suppose," Itsumi replied, trying to break the ice.

Mariah chuckled, "In a way, indeed. Itsumi Bakugou, right? The combination of ashen blonde hair, freckles and green eyes does make it clear." Her hand moved towards her, and Itsumi felt like a rabbit watching a snake slither through the grass.

'What is with her?' She asked herself, forcing her hand to grip Mariah's. They exchanged a very quick handshake before both let go and Mariah turned to greet Todoroki and Ojiro. Isaac didn't say anything, then, mercifully, the elevator pinged and the door opened.

Itsumi had expected many things, but not a vast corridor, that split in three routes to the left, right and forward after a few meters. When she reached the crossroad and looked to the sides, she noticed the corridors divided the underground level in four large rooms.

"What is this place?"

"This is Floor Underground One of the League for All Headquarters." A voice replied from behind her, making her jump. She turned to see another hologram.

At this point, Itsumi had figured out each Zuzu-9 had a different personality. The fact this one was a teen wearing a lab coat with rectangular glasses and pigtails on both sides of her head, however, left her speechless for a moment.

"Hello!" The apparition said with a smile, "I'm Zuzu-9-Delta, and I'm in charge of defending the underground levels of the Headquarters."

"There are multiple levels?" Todoroki asked, surprised.

"But of course. During World War Three, the United Kingdom built massive underground shelters for the people of London. Miss Mariah has used her connections to buy a building and all the six levels of shelters you see here, and then outfitted them for proper use."

"That latter part was mostly Midorikawa." She replied with a sad smile, "He really was driven."

"Yeah, I really miss him." Isaac's expression seemed even more saddened, but when Mariah looked at him there was a hint of anger in her eyes. Itsumi caught it for a second, however, before she calmed down.

"In any case, Zuzu, can we leave you to give them a tour of the lower levels up to five? I have some things to discuss with Isaac."

"You do now?"

"Yes, I do. Let's go." She replied, one of her thorny vines moving slightly.

Isaac nodded, "Very well. Izuku, I'll see you afterward to explain the training."

Izuku nodded and the four of them watched them leave on the elevator before turning to Zuzu-9. "Alright!" The hologram said, "Follow me. This first level is just a storage facility, so there isn't much to see. We will go to Underground two, were the laboratories are located, that's my favorite place."

Itsumi nodded, and they started following the girl.

-x-

Izuku looked around. Like Itsumi had said, this part of the underground facility was far more interesting than the first floor. For once, where the walls of the first floor where simple stone, here most of them had large windows that opened on many different rooms. In most of them, automatons were moving around, robot similar to the ones UA used for support: not made to fight, but rather to handle delicate items and wounded people.

"The League for All invests a lot in experimenting on new ways to traverse the Multiverse and safety precautions for it. On this level, we mostly do chemistry and medicinal research. Nothing too dangerous: the most contagious or deadly illnesses encountered in the Multiverse are usually left to study to their home world, but we can't count on blind luck and hope no one will ever contract an illness and come back unaware, so we try to make our own plans." She pointed to her left, where Izuku noticed was a full-blown medical bay, even if right now it was empty. "Miss Uraraka doubles as our main doctor, although Miss Mariah also has contacts in both the Guardians and the City Hospitals to ensure we can bring in proper doctors and healers if the need arises."

Izuku nodded, "So there are other labs?"

"Indeed. Underground Three, where we are going next, is my absolute favorite!"

"Wasn't that the same for Underground Two?" Ojiro asked. The AI ignored the question as she led them down the stairs.

Following her, they soon arrived at a taller floor that was, yet again, different from the ones above. Unlike that one, this one was a single, enormous room, with many large machines littering the place. Izuku noticed that a few of them seemed to be assembly lines for something, but far more were completely alien for him. He was sure for Hatsume this would have been paradise. He looked impressed at robots similar to the ones from the floor above working around, the loud sounds he recognized from the Support Course lab everywhere, just augmented tenfold.

"This is Underground Three, Mechanical and Technological research!" Zuzu-9 shouted to make herself heard over the noise. "As you can imagine, we chose a floor this low to prevent the sound to be heard above ground!"

"What are they building?!" Izuku shouted back.

"That depends on the group! This one over here is testing a new model of a weapon created in the Suitverse we came up with to better the efficiency. If it's successful, we will integrate it in our defenses."

There was a whirring noise, and then the sound of an explosion. They all turned around to watch a robot look down to the remains of the machine he was carrying. "I don't think it worked!" Todoroki said.

Zuzu-9 nodded, "Follow me, I should introduce you to the last guests!" She shouted, and they started following her, making their way on clear yellow lines painted on the ground, that designed a path to keep them at a safe distance from the various machines. Sometimes a robot would zoom by, heading from one to another. Izuku watched one finish to work at a lathe before rushing away with a piece of metal to who knows where.

"Originally, we didn't need a laboratory this big. However, since mister Midorikawa and Miss Midoriya introduced Project Initiative, the floor has been completely reshaped, and here is the crown jewel of our research facility."

She pointed forward. There, a man and a woman were walking on what seemed to be a large circle of metal, big enough to allow a car to pass through.

"Is that…"

"A portal!" Zuzu-9 explained, "The intent is to build the first fully functional portal augmented by magic! With this, we will finally be able to end the age of Wanderers and connect the worlds of those members of the League that wish to help in a safe way! We will be able to take home anyone that is lost!"

Izuku nodded, observing it, then his eyes moved to the two people working on it, crouched behind two different parts of the machine.

"Hello, mister Midoriya, Miss Hatsume!" Zuzu-9 shouted. The two people looked up.

The Izuku Midoriya, this time around, had shorter hair and was wearing only a light blue tank top. That made evident not only his physique and the many scars that littered his side, or the sweat that he was producing working in the heat, but also the fact that his right arm was made entirely of metal. A prosthetic, but one far more advanced than Izuku's world produced. Izuku had seen some that were almost like the real thing, but this was different, a piece of work that seemed perfect.

"Oh hello Zuzu. Phew, this is quite the ordeal." He said, "I wish Mei was here. She would have a few words for this baby here." He stopped, before staring at the girl next to him, "Ah, not that I don't like working with you, Hatsume."

Izuku's eyes shot at those words to the left and he stared at the woman. She had the same pink dreadlocks and the same glasses of Mei, so at first he had thought that would be it, but when she removed them to clean away some sweat with a glove covered in oil she revealed yellow eyes instead of green-yellow, noticeably lacking a cross. In her mouth were glistening four sharp canines. She was also a bit older and a fair bit shorter.

"You can say that again, Power Suit." She replied taking a sip of water. As she looked around, she observed their stunned expressions. "Oh, sorry, where are my manners. Himiko Hatsume. Nice to meet you all."

Izuku was fairly sure he heard Todoroki clench his teeth together and felt the heat in that part of the lab rise. "Fucking Multiverse…" Ojiro whispered.

Deku stared at the girl with Hatsume's hair and Toga's face bend her head slightly to the left in confusion. He couldn't help but agree.

Alright, so, the Headquarters of the League for All and the kind of people you meet there. Boy did I work a lot. And of course, first I must do a round of thanks for the authors that allowed me to borrow their Izuku. As usual a reminder that nothing in here is canon in their respective fics, unless they specifically say otherwise.

Spider-Man Izuku is based on the character from The Infamous Man 's fic Amazing Fantasy, on SB and FF .net, the same another character introduced before is from.

Izuku the Green Scar, currently forty-five years old in this universe (and I'm sure that raises questions for Green Scar readers), comes from The SB Green Scar worldbuilding thread by Quantum01 and the fic based on the said thread by Pro-man. The Green Scar is a MHA/Star vs the Forces of Evil crossover with excellent worldbuilding!

Izuku alias Dekiru: The Fusion Hero comes from the fic of the same name by | OmegaInfinity | . He only has a short appearance in this chapter, but I assure you he, like the other characters introduced here, will play a larger role.

And last but certainly not least Izuku alias Power Suit comes from the fanfiction Rejected Stones by FullParagon, also available on SB and FF .net. He drew the shortest straw in terms of introduction in the chapter I fear, but on the plus side that means he will be there when the next chapter starts.

Once again, big thanks to them for giving me permission! Go read their stories, I assure you it's worth the time investment.

As a fun fact, I actually cut an original Izuku from this section of the story. As ANOTHER fun fact, he was actually the only Izuku with the name spelled differently. I'm an idiot, I know.

But we are also introduced to Mariah in this chapter. And oh boy is she an important character.

Do tell me your impression on the headquarters and the characters in them, and on the chapter as a whole.

(Also, finally posting again on Monday/early Tuesday again. What a day)
