AN: Hi everyone! Oath of Devotion here with a little plot bunny that just wouldn't leave me alone. The idea came to me after I read a story who had a similar plot (Izuku has to take care of another Izuku's kid) but that story was serious, had drama (and was probably better written) and for what I remember, the author only wrote about two kids. The idea of this story is for it to be a little silly and funny, except for this chapter that has a lot of just background story and setup. If somebody knows what story I'm talking about, I would appreciate you told me. Anyways, thank you for passing by and hope you enjoy this!
Update: Corrected some mistakes on the names of some characters.
It was a calm day for the class 1A, classes were about to end for the day and everyone was discussing what they were doing or the upcoming School Festival.
Aizawa was taking a nap peacefully on his sleeping bag thanking his stars that nothing was bothering him today.
A chill ran up his spine, maybe it was too peaceful...
As soon as the thought entered his mind he muttered a curse as a gust of wind scattered some papers on his desk, he quickly stood up and watched along with every student in the classroom as what looked to be a bright blue portal of some kind appeared on the entrance of the class.
Most students stood up and took a defensive stance, ready for whatever or whoever was going to come out from the portal. However, no one was prepared for what came out of it. A man fell out of the portal stumbling face first into the ground.
"Ow, crap, well that was unexpected" –the figure took out what looked like a voice recorder
"Note to self: there's a force current during transport. Minimize the entrance zone to reduce the force as much as possible."
The somewhat familiar man shook the dust off himself and looked around, facing the class he smiled brightly and said
"Hello everyone! And hello Izuku, or should I say, Hello me."
The man that came out of the portal had an uncanny resemblance to Izuku. Fluffy green hair, large green eyes, freckles in a diamond pattern, however that's where the similarities ended. The man was taller and looked older than Izuku, on his late twenties to early thirties if anyone was to guess. Also, what he was wearing was something no one would ever think Izuku would wear, he was wearing a green t-shirt along with blue denim overalls, a pair of square glasses adorned his face and on his hips a large toolbelt that was filled with all sorts of tools, his outfit was complimented by thick leather gloves and black combat boots. He was also holding in one of his hands a silver metal box. Izuku was speechless, just babbling to himself.
"Well, it looks like my invention worked perfec-augh!" The self-proclaimed Izuku said but was interrupted by Aizawa who quickly wrapped him with his scarf.
"Everyone be careful, stand aside while I call in for some help." Said Aizawa while keeping an eye on the older greenette.
"Hello Aizawa-sensei. Nice to see you're around on this universe too." -said the man with a smile while Aizawa kept his eyes on him, glowing red– "Don't worry about using your Quirk on me, I can't use it anyways since my arms are tied up." -He said in a gentle tone as if he was having tea with the man that had him bound. After a couple seconds All Might along with Ectoplasm came and took the man out of the classroom. Once their teachers left, chaos erupted between the students, most of them jumping at Izuku.
"Midoriya-kun! Did you saw that? That was totally you from the future! This is like a Sci-Fi movie." -Exclaimed Ashido while Izuku just stammered
"I-I I mean... ehh..." Izuku was still in shock since he just met what looked to be an older version of himself
"Maybe it was not him, maybe it was a villain that wanted to attack us disguised as Midoriya." Suggested Hagakure
"But then why did he looked like an older him? Why didn't he look like Midoribro looks now?" -asked Eijiro. The three teens scratched their chins while thinking of something, but were interrupted by the voice of Ida.
"Everyone calm down, the teachers will take care of this, and I'm sure will tell us everything once it's sorted, now everyone take your seats and stop disturbing the order of the class." -Mina and Eijiro looked disappointed while returning to their seats and Izuku sent a grateful look his way. The murmurs and conversations didn't stop however, everyone thinking of their own theories of who the strange Izuku-lookalike was.
About an hour passed an Aizawa returned to the classroom with the man in tail. Most of the students looked excited while Izuku felt, for a split second, that his teacher sent an annoyed glare his way.
"Ok everyone, we have a situation on our hands, however I'll let this problem child" -said Aizawa pointing at the grown up Izuku- "explain since I don't get paid enough to deal with this." -said greenette was smiling broadly without a care in the world and once Aizawa jumped into his sleeping bag he took it as a queue to speak.
"Hello everyone!" -Izuku exclaimed loud and confidently his smile never faltering- My name's Izuku Midoriya, but you may call me DeusEx the number one Hero of Japan! Exclaimed the greenette proudly while gasps were heard all across the room. Not to lose a chance Mina shot her hand in the air and asked
"Are you really Midorya-kun from the future?"
"Hello Ashido-san, nice to see you. Not really, I'm a grown-up version of me here" -he said pointing at the Izuku who was currently fainted in his seat after he heard he was the number one hero- "but from another universe. I'll explain in a second, so please if you can keep your questions until the end."
"What the hell do you mean number one hero? Where the hell am I in the future!?" -yelled the resident explosive boy of the class
"Oh Kacchan, nice to see you're here too. It's almost adorable to see you shrunk down, like an angry puppy almost" -DeusEx said with a smirk while some of the class tried to suppress their laughter
"I will end you!" -screamed Katsuki while activating his quirk. DeusEx just chuckled and took out from his toolbelt what looked to be a pen and pointed it at Katsuki, a red laser came out from the pen and when he tried to activate his explosion nothing happened
"And as short tempered as I remember you, nice to see some things never change." -said DeusEx with the smirk still present on his face
"Bakugo, sit down right now, another display like this and you'll regret it." -Said Aizawa from his sleeping bag while Katsuki just cursed under his breath and returned to his seat.
"Was that your quirk Midoriya-chan?" Asked Tsuyu while DeusEx sighed
"I guess the "questions for later" won't work on you, Isn't that right Tsuyu?" -Said the tall greenette with a tired voiced while Tsuyu croaked happily, apparently this Midoriya learned that she wanted to be called by her name- "to answer your question, yes and no. My quirk is called Copy Printer, basically whenever I see someone using a Quirk, my mind automatically thinks of a blueprint that allows me to create a machine that works exactly as that Quirk. However, with the help of my lovely wife we have been able to upgrade the blueprints for the machines and have better or more efficient versions of those Quirks. This" -he said while lifting the pen that he used on Katsuki- "was created based on Aizawa-sensei and his Erasure Quirk." A chorus of murmurs went around the room but a squeal of delight was heard coming from the gossip queen of the classroom.
"You're married in the future?" -asked excitedly the pinkette while Izuku who was starting to recover almost fainted again when Mina asked the question.
"Again, not exactly the future, different universe. But yes, I'm married, why is it so surprising?" -asked DeusEx pretending to be offended by the question and smiling at Mina who giggled and shot her second question- "To who?" -the question deafened the room, DeusEx smiled and closed his eyes as if recalling a memory.
"Well, I don't know if she exists in this universe, but her name's Mei Hatsume"
"Mei! As in support course Mei? The girl that can't be separated from her "babies" Mei?" -Asked Toru while not-their-Izuku's smile widened
"Oh, she exists here too? Nice. And she's also in the Support class. That's nice. Is Power Loader-sensei here too? I almost want to go and say hi"
"DeusEx-san was Aizawa-sensei not your sensei?" Asked Kyoka curios about why he seemed almost nostalgic
"Not for my first year. First year I was on the Support Class, since my quirk is literally about creating gadgets, it was a good fit for me, but some things happened and on my second year I got assigned to the Hero class along with you guys. Well, let's not waste any more time. Now for the reason I'm here today" -said the green hero while pulling what looked like a water gun from his belt and pointing it at Izuku, who looked a little out of it. A second later the weapon was confirmed to be a water gun judging by the stream of water that came out of it and hit Izuku on the face, the boy gasped and covered his face to block the water while DeusEx grinned unashamed of his actions
"Are you with me dude?" -he asked to his younger version who only nodded not trusting his voice- "Good, cause now comes the important part and I need you fully awake ok?" -he asked with a serious face to the boy who nodded and sat straight on his desk. The older doppelganger nodded approvingly at the younger version
"So as I've mentioned before, I come from an alternate universe, we've already said a couple differences. I'm under the impression that our Quirks are different" -said DeusEx while looking at Izuku who nodded to confirm- "and also as I just told you, my first year I wasn't even in this class, and as you can imagine that in itself can result in thousands of differences between our universes. Anyways that's not really important, what's important is that my universe, but not only mine, hundreds of others alternate universes are in danger. We're facing a threat so big that it has already consumed entire universes." -Izuku's mind was running at a mile per hour, had All for One won on DeusEx universe and was running rampart across other places? Was it an enemy from the future that he would eventually face?- "Who?" -was the only thing he asked to his older alter ego
"Izuku Midoriya, also known as Ragnarok" -the answer from the greenette stunned everyone in the room into silence. DeusEx waited for about a minute for the information to settle on everyone and he continued.
"Thanks to my machine I'm able to scout superficially into other universes timelines." -he continued once he felt the shock left everyone- "by what I was able to see that Izuku had a way worse life than any of the other Izukus I've met, and trust me, I've met a fair share of myselfs. Whoever he still got you know what from you know who" -said DeusEx looking at Izuku while grabbing a strand of hair from his head, Izuku got the message, but his classmates were confused by the statement, someone tried to ask a question, but DeusEx almost screamed to continue the tale- "however, once he got accepted into UA a certain someone whose counterpart may or may not be on this room right now -said DeusEx while looking at the window, however some of the teens looked at Katsuki suspiciously -took it as a personal task to make his life even more miserable, this however ended up backfiring as he awakened a quirk that let him absorb other quirks." -Izuku's eye's widened, that version of himself apparently had One for All and All for One on himself at the same time- "With that power he called himself Ragnarok started stealing all the quirks in the world indiscriminately and quite literally destroyed his entire universe, once his universe was completely done, his mind was damaged to the point where only the instinct to destroy remained. With a combination of several quirks he was able to open a portal into another universe, and he started his rampage across realities. Now, he even has the ability to duplicate himself and attack several universes at the same time" -Fear settled into the hearts of the young students in the room. A villain capable of destroying entire universes, was anyone even capable of winning against a threat of that level?
"A-Are we... next?" -asked Momo in a really small voice, the question iced everyone's blood and DeusEx smiled widely
"Don't you worry about it Yaoyorozu-san there's two things preventing Ragnarok from coming in here. First of all, right now Ragnarok is trapped, or should I say, contained in my home universe. Right now, he's not able to hop universes thanks to a contraption built my Mei-chan and me that combines Quirks to negate Ragnarok portal ability. This however doesn't make him less dangerous, he has destroyed a good portion of my world and while we have managed to keep casualties to a minimum, we are aware that my machine won't last forever."
"So, are you here to ask help from the heroes of this universe then?" -asked Denki while DeusEx shook his head.
"Not exactly, I've already gathered quite a collection of Izukus from other universes who were under attack. Also, even if I wanted I can't pull anyone from this universe, which brings us to the second reason why you guys are safe. This universe is what I've called a "mainline" universe" -seeing the confusion on everyone's face DeusEx turned to Izuku.
"You know how some people think that the universe revolve around themselves" -said the man giving a taunting look to certain blond kid in the classroom who just growled at the insinuation- "Well my dear me, in your case it's quite literal" -Izuku just blinked confusedly
"W-what do you mean?"
"Exactly that my closest friend who happens to be me. Without you, there's no universe. In the hundreds of millions of thousands of probabilities in the multiverse there has to be one constant. In the case of our multiverse that constant happens to be you." -Izuku felt his head explode, he wasn't sure that he was THAT important to be considered basically the center of the universe- "To explain with more detail" -said the man while grabbing a piece of chalk from the teacher's desk and drawing a line across the chalkboard- "Imagine this line right here is the original universe right?" -he asked and turned around to see everyone's eyes on him, including Aizawa who looked interested in the explanation- "now imagine that this point right here is the point where Izuku is born, sometimes a Universe, as for example mine where I was born with a Quirk... a different Quirk than Izuku here, when this happens that universe becomes a "branch" -he said while drawing a line coming out from the first line- "However sometimes a universe only difference from the original is what Izuku decided to eat one morning, what color of ink he decided to use to write something, something that may look insignificant, but is enough to create an entirely different universe. These universes usually just return to the natural flow and fuse to the original, however that small moment when it diverges is what I call a "mainline" -some students looked confused, other looked deep in thought and Izuku was just captured by the words coming out from his alternate's mouth, trying to process everything at once.
"Now the original universe is out of reach from Ragnarok and for me, however my machine was able to locate the original universe and after some observations I was able to locate the mainlines, because of the location of this mainline and the precautions we've took to contain Ragnarok he won't be able to find this universe for quite some time -While some of the students looked relieved, Aizawa looked at DeusEx- "for some time? So are we not completely safe?" -The question worried the students again but the smile on the greenette didn't go away
"For Ragnarok to be able to find this universe the mainline would have to become a branch in an irreversible way. Me being here is already branching the mainline, but if I were to leave right now, the natural flow will drive you back to the original universe. For the universe to completely become a branch Izuku would have to do something that would wildly alter the natural flow, or if a small but constant change prevailed for a prolonged period of time, by my calculations around the time Izuku turns twenty-five years old. So, we have a very generous window to play around and at the same time keep you guys safe from Ragnarok." -the time/dimension/universe traveler finished and while some of the teens where very confused, the others who managed to grasp the explanation looked more comfortable. Momo raised her hand and DeusEx gestured at her to talk.
"There's one thing I don't have clear Midoriya-san. If you can't take help from this universe to fight the villain and we are safe from him. Why are you here? What can you possibly need from us?" -The smile on DeusEx turned into a mischievous grin as he looked at his younger alternate self- "You see Yaoyorozu-san, as I said before there's a reunion of Izukus at my home universe and most of them have families that they hold very dear to their hearts. Besides that some of them even have children" -Mina and some of the other girls of the squealed in delight imagining the kids of their green-haired classmate- "so Izuku since we cannot ask you for your help in our fight, and you're safe from danger here, I need to ask you in behalf of our other selfs, would you please take care of our babies for a little while?" -he asked while putting his hand on Izuku's shoulder and kneeling down to Izuku's eye level. Izuku himself was stunned, he had kids? Well technically not him, all of this alternate universe talk, along with the other topics were very heavy on his mind.
"I-I mean, of course. How can I say no? It's the least I can do to help right?" -DeusEx smiled brightly, he had very little doubt that he would say no, he was himself after all, but who knows? Every universe is a little bit different always.
"Excellent. Thank you so much Izuku." -DeusEx stood up and spoke to the class- "After Aizawa-sensei so kindly took me to meet Principal Nezu" -Aizawa, who had returned to his sleeping bag shot him a glare and turned around to try and nap- "And after I explained the situation to him and the teachers, we decided that the kids would be safer here in campus, so I wanted to explain everything to all of you and avoid the chaos that would ensue if Izuku suddenly appeared with a bunch of kids on the school. Please give him a hand if you can" -he gave Izuku his mischievous smile again- "after all, you may see a couple of familiar faces. Well, that's it from me. Thanks a lot for hearing me. See you next time!" -DeusEx was already walking out of the door, leaving behind a chorus of screams and unanswered questions, as he was already out of the door, Aizawa took Izuku's arm and started pulling him, walking behind his universe traveling counterpart.
The trio reached the training area and Izuku saw that All Might and Principal Nezu were waiting for them.
"Young Midoriya! Everything went okay?" -asked All Might and both greenettes looked at each other wondering who he was talking to
"Yes, everything is okay" -said both at the same time causing the blonde man to chuckle
"Well mini-me, I'll be back once everything is ready the bring the first one here" -said the taller Izuku while the other asked
"You're bringing them one by one? I thought you were bringing them all at once"
"No no, oh my god no. There are complications with hopping between universes, not to mention energy usage, and other things that had to be taken into caution -DeusEx started muttering to himself so quickly that Izuku couldn't understand what he was saying
"A-Ano, Izuku-san, you're muttering" -It was odd for the boy to be on this side of that line
"O-Oh, sorry. I guess some old habits die hard, am I right?" -both of them smiled and DeusEx started touching buttons on the side of his silver box.
"So, you can expect me back in about 3-5 business days" -he said grinning- "no, for real, between 3 and 5 days if my calculations are right, also just so you don't get startled, since you are the constant my portals always open around you, so be on the lookout, okay?" -the man smiled at the boy and the blue portal opened behind him.
"Wait! I have so many questions, so many things I'm worried about!"
"Don't worry my dude. Just remember, you're the constant, any decision, any action, anything you do, is okay as long as you're happy with it. Remember that!" -After saying that he jumped on the portal and it closed behind him.
Izuku wanted to pinch himself to see if he was still sleeping and today was just a crazy dream, but he knew that his crazy days had just started.
AN: And that's it for the first chapter! Hope it was interesting. Next chapters won't have as much "universe technical talk"... hopefully. Anyways from here on out it's Izuku and the class meeting the kids of alternate Izukus and whatever ensues from that. Thank you for reading. Until the next one.
