What if Deku...

Chapter eight: You should have seen this coming

The audience in the theater room kept by the Realmcrafter Talespinner69 all suddenly woke up, as if all of them had been asleep for a very long time. "Yeah, sorry you all had to be put to sleep like that," Tale apologized from where he and Kotaro stood in front of the big theater screen, "I got caught up with other things."

"Wait, what show is this?" Hound Dog asked.

"The one with alternative Dekus," Kotaro explained, "The last one had Deku tell the UA staff about his life prior to UA."

Hound Dog nodded in thanks. "Thank you."

Turning to look at Tale, Izuku asked, "So what were you up to while you had us all asleep?"

"Well I moved, for starters," Tale said as he began to list things off of his fingers, "I'm still sort of dealing with a personal tragic loss, oh and I recently finished up a realm I had been working on for quite some time."

"Based on our world?" Monoma asked.

Tale gently shook his head. "No, it was a Pokemon realm. Speaking of, I recently sent my Naganadel, Wyrmscsle, to bring a DVD of one of the realms you all have already seen to Lego so he can show it to his audience. Hopefully Lego doesn't feed anything really spicy to Wyrmscale because its got a Timid nature."

Clapping his hands together, Kotaro said, "Anyway, we got the next Deku realm ready and reading to go. And hoo boy, it's looking to be a doozy!" Kotaro and Tale then got the big theater screen going as the audience looked on as the next realm with an alternate version of Izuku began to play.

...

The villain Muscular was going on a rampage after he had escaped from Tartarus for the third time this week. Among the pro heroes fighting him were UA teachers Aizawa and Hizashi. "Yo Sho, this is bad!" Hizashi exclaimed, "This is Muscular's third escape from Tartar Sauce this week! We got to do something to stop him!"

"It's Tartarus, not Tartar Sauce," Aizawa said dryly.

"Sorry, I got seafood cuisine on the brain since I'm set to take my new girlfriend out for dinner tonight at a seafood place!" Hizashi replied.

"So Muscular escaped from Tartarus," Aizawa in the audience said, "And Hizashi's now in a relationship. Interesting."

"I'm surprised you aren't worried about Muscular being loose in this realm, Aizawa-sensei," Izuku said in a surprised tone.

The underground hero turned to look at Izuku. "That would be due to the fact that I have a very strong feeling that the you in this realm will resolve the matter."

Over where Hawks and Mirko were both struggling to fight Muscular, the strong villain laughed out loud. "Bhwuhahahahaha!" Muscular laughed, "No one can stop me now! I'll kill all of you, then I'll go on to kill more people, then I'll set fire to the first orphanage I find after making sure everyone's locked inside, and then just for shits and giggles I'll go to that special academy for autistic kids and rape the first kid that I get my hands on!"

"Why would you do all of that?!" Hawks yelled, shocked at what Muscular declared that he was planning to do.

"Because I'm fucking evil, that's why!" Muscular yelled.

"More like fucking insane," Dabi in the audience said dryly, "Seriously. Why did we ever recruit that guy?"

A lot of the villains, including Shigaraki and All For One, shrugged in confusion. "Well let's hope that Young Midoriya puts a stop to that villain," Toshinori said, "I'm certain that he will not only save the day, but do so in a manner that shows complete and total heroism!"

Looking at his theater screen, Tale said, "...I don't know..."

As Muscular rampage continued, he was punched really, really hard in the top of his head by the large draconic fist of Ryukyu in her dragon form, knocking Muscular out and clamping her draconic hands around him as Izuku got off of the Dragoon Hero's back. "Thanks for the lift, Ryukyu," Izuku said as he moved to walk to stand right in front of the knocked out Muscular.

Ryukyu nodded in acknowledgement as Izuku placed his right hand on Muscular's face, all five digits touching him. Suddenly, purple lines appeared on Muscular's face as he moaned in pain while he was knocked out. By the time Izuku was done, all of Muscular's excess muscles had receded, and Ryukyu let him go, allowing him to drop to the ground like a sack of potatoes.

Aizawa and Hizashi looked surprised by what the class 1-A boy did, then saw it as Izuku made his own muscles grow like how Muscular did, before shrinking his muscles back down to their normal form. "Hmm, I wonder who would be able to make the most use of this quirk I just took from this villain," Izuku wondered aloud.

(What if Deku had the All For One quirk)

"That green haired brat has sensei's quirk in this realm?!" Shigaraki in the audience exclaimed.

"Young Midoriya has All For One's quirk in this realm?!" Toshinori exclaimed, sounding just as surprised.

"I was shown struggling with a villain but Ryukyu scored an easy knock out on said villain?!" Mirko exclaimed, "What the fuck?!"

Ryukyu turned to face Mirko, a dry look on her face. "...That's all you care about, rather than how someone has the power to take quirks from others?"

Looking up at the theater screen, Tale said, "...Huh. I was sort of suspecting this."

"Excuse me?" Izuku said, sounding surprised.

"Oh yeah," Kotaro proceeded to explain, "There's a number of realms crafted by those of Tale's kind that show you obtaining the power of All For One."

Where he sat in the audience, All For One was laughing his ass off. "I can't believe it!" the symbol of evil laughed, even kicking his legs a bit, "This ought to put a bee in All Might's bonnet!" Over where he sat, Toshinori could only scowl.

...

Later over at UA, Izuku's classmates were cheering for how he had bested a villain. "And that was the one who killed Kota's parents," Uraraka said, "You're an amazing hero, Izuku!"

"Yeah, and props on how you teamed up with Ryukyu kero," Tsuyu remarked, "Especially since that villain the two of you took out was very clearly nuts."

"The power to take, hold onto, and give quirks," Tokoyami remarked, sounding serious, "A truly potent power, to be sure. And the gateway to darkness if used for evil."

Izuku nodded in agreement. "Yes, my quirk can be used for evil if used incorrectly." Giving a gentle shake of his head, Izuku went on, "But the same can be said of any quirk. I intend to prove that my power can be used for good, because I want to do good! And no one can tell me otherwise on the matter!"

"...I still have my concerns about if that evil power can really be used for good," Toshinori in the audience said, "But it would seem that the Young Midoriya in this realm is just as steadfast set on the path of justice as our own."

"Why am I not surprised that Midoriya, regardless of his quirk, wants to be a hero?" Aizawa asked in a rhetoric manner.

Where he sat in the audience, Izuku was mumbling to himself on what all could be done if the power of All For One was in the hands of a hero rather than a villain. As Izuku mumbled, Uraraka turned to look at him, a hint of amusement on her face as she saw Izuku in another one of his trademarked famous mumble fests.

"Well either way," Yaoyorozu said, "You did good, and I have no doubt that you will go on to be one of the finest heroes we've ever seen." The rest of class 1-A all cheered in agreement with Yaoyorozu, showing that they were putting their whole support behind the green haired boy.

Izuku was surprised by the warm reception that his classmates and friends were giving him. It touched him to see that so many people were behind him one-hundred percent. It made him want to work all the harder to prove that he was actually worth all of the effort that all of them were showing him.

...

Later in one of the hallways of the main UA building, Izuku was on his way to see Mei Hatsume because several of his classmates have taken umbrage with some of her behavior as of late, and he was elected as the spokesperson who would bring the complaints right to the eccentric girl directly. Along the way, Izuku accidentally bumped into Monoma of class 1-B.

"Ah, watch where you're-" Monoma began, only to stop short upon seeing that it was Izuku. "Oh, you're that Izuku fellow from 1-A," Monoma said, "Apologies."

"Why am I being courteous to him?" Monoma in the audience nearly exclaimed.

"Well the Deku in this realm has the power to take and give quirks," Bakugo pointed out, "Maybe the you here is being wise not to piss on Deku's shoes."

"Oh, you're in class 1-B," Izuku said, "Thanks for the courtesy."

Holding out a hand for a handshake, Monoma said, "Well you have proven to already be a fine example of what it means to be a hero, even though you're still in your first year. Bravo."

Smiling, Izuku accepted the handshake from Monoma. "Thank you. Here's looking forward to our classes working together." The two shook hands, then went on their separate merry ways, with Izuku muttering something about Mei having to stop getting too cozy with him due to how Uraraka doesn't like it.

"Too cozy?" Mei in the audience repeated in a curious tone.

Shrugging, Kotaro said from where he and Tale stood in front of the big theater screen, "Yeah, those of Tale's kind occasionally take that one time you were laying on top of Izuku after falling onto him, where you had you boobs pressed right into him, and use it as an excuse to make Uraraka jealous."

"W-What?!" Uraraka stammered in embarrassment.

Tale gently shook his head. "I've never done it in any of the realms I've crafted, if it helps."

...

After Izuku got done talking with Mei, he made his way back to the dorm building where he and his classmates all resided. However, upon walking in, Izuku saw to his horror that all of his classmates were laying on the floor, covered with blankets as only their heads and feet stuck out. Looking over the students were Aizawa, Hizashi and Hound Dog.

"Senseis!" Izuku exclaimed as he ran over, "What in the name of Odin happened here?"

Sighing in a resigned tone, Aizawa said, "Monoma. According to Uraraka, Asui and Iida before the three of them passed out, Sekijiro's student Monoma somehow was able to take the quirks of every student in 1-A."

"That hysteric shit stole our quirks?!" Bakugo in the audience exclaimed as most of the 1-A students all proceeded to throw junk at Monoma, making him cry out in pain.

"I invoke the names of Norse deities?" Izuku said in a curious tone.

"Aside from you," Hizashi said, "Did Monoma make physical contact with you at any point?"

"Well we shook hands with one another earlier," Izuku said, "But this doesn't make any sense! Why would Monoma do this?! Copy my quirk then use it to steal the quirks of everyone that's in class 1-A?"

Hound Dog was about to speak up, but a loud explosion from outside cut him off. The senseis and Izuku ran outside and saw Monoma, floating in the air, looking like a horrific monstrosity that was a mix of the nineteen students in 1-A that weren't Izuku. "At last!" Monoma yelled, "Finally at last someone other than those blatant attention hogs in 1-A will get the chance to stand in the spotlight!"

"Oh not this again," Juzo in the audience remarked in an exasperated tone, "Why does Monoma have to have such a raging hate boner for class 1-A?"

Monoma looked as if he were about to speak up, but Yosetsu cut him off. "It is..." Yosetsu began to say, his tone leaving no room for any arguments, "...a pretty...hateful boner."

Pointing right up at Monoma, Aizawa yelled, "This goes too far, Monoma! You will work with Midoriya to return everyone's quirks right now!"

"And allow them to be the face of everything again?!" Monoma shot back, "Why would I? It's not just me and my class who are forced to sit in 1-A's shadow all the-" Monoma was cut off when Dark Shadow popped out of him and moved to behind Monoma, grabbing him in a full nelson hold to try to restrain him.

"Ah hell no!" Dark Shadow yelled, "You done fucked with Fumi and his classmates for the last time, Hysteric Monkey Boy! You'll be giving them their quirks back pronto!"

"Why?!" Monoma yelled, "Why must everyone else always remain in the background? Why must 1-A always have all the attention?!"

"They're the main character class!" Dark Shadow shouted back as he and Monoma struggled, "Of course they're going to get all of the attention!"

"Wow, Dark Shadow is so meta in this realm," Kotaro remarked from where he and Tale stood in front of the big theater screen.

Nodding in agreement, Tale said, "Yeah. He's proven to be quite the character."

Turning to look at Izuku, Dark Shadow said, "Green Bean! I shall do what I can to help you deal with this squirrel hopped up on a gallon of pure espresso, but you will have to give the brunt of the effort in taking him down! You must take all of his quirks! Leave me for last, though!"

Nodding in the affirmative, Izuku said, "Got it!" Using a quirk he had previously taken from a villain, Izuku flew up to where Monoma struggled with Dark Shadow and placed his hand over Monoma's face. After a few seconds, Izuku was able to take a few quirks from Monoma before the mad boy of class 1-B got free and tried to make a grab for Izuku.

However, Monoma and Dark Shadow fell down to the ground with a crash. Looking up, Monoma and Dark Shadow saw that Izuku was now floating with a different power. "You took back the gravity girl's quirk!" Dark Shadow called up.

"Well of course I'd take Uraraka's quirk back as soon as I could!" Izuku called down, an angry look on his face, "It pisses me off that Monoma took the quirks of all of my classmates, but it especially pisses me off that he took Uraraka's quirk! She's the girl that I'm in love with!"

"Hot damn!" Bakugo in the audience exclaimed in amusement, "This Deku just confessed to being in love with Round Face!"

"He saved the quirk of one of your interns first thing," Mirko said to Ryukyu, "Pretty ballsy, if I do say so myself."

Where they sat in the audience, both Izuku and Uraraka blushed heavily in embarrassment. Meanwhile, some of the boys were cheering excitedly to see a fight between Izuku who has the All For One quirk and Monoma who was able to take the quirks of everyone from 1-A aside from Izuku whose quirk he copied temporarily.

Over where the villains sat, All For One himself said, "I'm actually liking this fight. I can tell it's going to be a real treat."

"I actually want to see this myself as well," Shigaraki said, "Two people both having been influenced by your power sensei, duking it out."

Izuku landed on the ground then, pulling up his pants legs to show the engine-like protrusions growing out of the backs of his shins, he sped right up to Monoma who slid back quickly while secreting acid from his feet. When Monoma was a good distance away, Izuku jumped up and, opening his mouth, shot out an incredibly long tongue that wrapped around Monoma's body.

Izuku tried pulling himself in, but Monoma shot a mix of electricity and tape at Izuku. The green haired boy conjured a mix of ice and fire to blast against Monoma's attack, causing an explosion of power when the two attacking forces collided. Izuku was soon able to pull himself up close to Monoma, but his punch failed to do much because Monoma hardened himself to keep the attack from hurting.

"That fucker's abusing the quirks of my crew!" Bakugo in the audience exclaimed, "That little shit!" Similarly, all of Bakugo's crew cried out in annoyance when they saw Monoma using their quirks to fight against Izuku.

"Hmm," Aizawa remarked, "So Midoriya has been observed having taken back the quirks of Uraraka, Asui, Iida and Todoroki thus far. Those are all of Midoriya's usual friends in class, if I recall correctly."

"He's saved the quirks of both of your girls in Eraserhead's class, Ryukyu," Mirko said to Ryukyu over where the two of them sat.

"...Yes, so it would seem," Ryukyu replied.

While his fist was trying to plow into Monoma's hardened face, Izuku took his free hand and slapped it into the other side of Monoma's face, and was able to take back a few more of his classmates' stolen quirks before he had to jump back and away from Monoma. "I shall still prove that 1-A isn't as top as they think they are!" Monoma yelled as he shot a laser blast from his belly button.

Acting quickly, Izuku produced a shield from his arm and used it to block the laser blast. Monoma shot more tape at Izuku, but the green-haired boy countered by casting a wave of acid at the tape, dissolving it. Izuku then faded from sight as he turned invisible, making the blonde boy of class 1-B look around in confusion.

"Where the hell did he-" Monoma said, only to stop short as he felt something jab into him before stunning him; Izuku became visible again, revealing that earphone jack cords were now growing out of his earlobes and were jabbing into Monoma to stun him. "Ahhhh! You son of a bitch!" Monoma yelled as he was convulsing from the attack.

"Now Izuku's using the quirks of all of the other girls in class," Aizawa in the audience remarked, "And given that he's literally just gotten them, the way he uses them in combo is impressive."

"I'm amazed he knows how to effectively use my quirk," Yaoyorozu remarked, "I mean you need to know the chemical composition of what you want to make in order to make it."

"Yes!" Mina cheered, "Izuku saved my quirk from that blonde bastard in 1-B!"

"I hope you all know that I would never do something like this for real!" Monoma shouted.

While Monoma was stunned, Izuku used the opportunity to take back more of the quirks that Monoma had stolen from class 1-A with the temporary copy of Izuku's quirk he had. Jumping back before Monoma recovered and tried to make a grab for him, Izuku got a good distance away before he looked up into the sky.

Holding a hand to the side of his mouth, Izuku shouted, "Come to me, my animal friends! I need your help here!" A few seconds later, a stampede of animals, including a few peacocks, a full grown African bull elephant, and a pair of silverback gorillas, ran over and rushed past Monoma, slamming him a bit. The gorillas even stayed and helped Dark Shadow to restrain the mad blonde boy.

"Did Green Bean just use Koda's quirk to pull a Jumanji?" Hizashi in the audience asked.

"Could Koda potentially do that for real?" Aizawa asked.

"Holy shit, Izuku here knows how our quirks work inside and out," Kaminari remarked.

Shrugging, Tale pointed out, "Well he has shown great skill in quirk analysis. It would make sense that he'd have an idea on how to work with your quirks."

While the gorillas and Dark Shadow had Monoma restrained, Izuku used the time to take back more of the stolen quirks. Monoma was able to break free from the gorillas who then fled, but Izuku was able to get some distance before that. Izuku threw tape around Monoma, then he zapped him with electricity, then when Monoma recovered from that Izuku blasted him with a couple of explosions.

Monoma got through all of that and tried to rush Izuku to strike him, but Izuku hardened himself to make Monoma's efforts moot. "Yeah, that's not going to work now," Izuku said as he jumped back a bit.

"Midori-bro got back the quirks of the rest of our crew!" Kirishima in the audience cheered, "And he's using them in a hella manly way!"

Even Bakugo couldn't help but smirk. "Not bad, Deku. Not bad at all."

"I think he's gotten back over half of the stolen quirks by now," Toshinori said, "But once he gets them all, what will he do?"

"If this me has the same attitude and ideals as I myself do," Izuku said, "Then he'll give all of the quirks back to everyone."

Monoma jumped back from Izuku, but he was caught in another full nelson by Dark Shadow, who also slammed his head into the back of Monoma a few times. As Monoma stood there tired and falling to one knee, Dark Shadow yelled to Izuku, "Now is your chance! Take back the last of the quirks this turd stole from you and Fumi's classmates!"

Nodding in understanding, Izuku made his way over to where the weakened Monoma stood restrained by Dark Shadow. Izuku placed his hand against Monoma's face and took back the last of the stolen quirks. Dark Shadow was sucked back up into Monoma, but soon later he popped back out of Izuku.

"Aha! I live again!" Dark Shadow cheered.

Growling angrily, Monoma said, "I'll just copy Midoriya's quirk and take back all of the quirks that I had!" Monoma then slapped his hand into Izuku's face, smirking as he attempted to copy Izuku's quirk.

...Except nothing happened.

Smirking himself, Izuku said, "Yeah, Dark Shadow was the last quirk that I took from you. I took all of your other quirks first. ALL of them."

Monoma's eyes widened in shock. "...No. You took my own quirk?!"

"Boom, bitch!" Bakugo in the audience cheered, "That's what you get!"

"He'll give my quirk back to me," Monoma said hopefully, "Right?"

Shocked to learn he was quirkless now, Monoma stumbled forward a bit before he fell to his knees and fell over, laying face down on the ground. Then all of his clothes exploded off of his person, leaving Monoma in only his birthday suit.

Izuku, Dark Shadow, and the senseis all looked down at where the naked Monoma laid face down on the ground, thankful he was laying face down. As he looked at the downed Monoma, Hizashi asked, "...Can I stick the stem of a flower right into his-"

"No, Hizashi," Aizawa said dryly, prompting Hizashi to snap his fingers in disappointment.

...

Later, class 1-A cheered for Izuku as he returned all of their quirks to them. "Let's hear it for Izuku, everybody!" Mina cheered as she held up Izuku's right hand, "This cool dude just saved all of us! Three cheers for Izuku!" Everyone in class 1-A then proceeded to go 'hip hip hooray' as they celebrated their classmate who saved them all.

In the audience, the 1-A students also cheered for Izuku, both on screen and in the audience with them. Meanwhile, even Toshinori was impressed. "...So he really did use All For One's power to do good," the former Symbol of Peace said. Smirking in amusement, Toshinori added, "If anyone could figure out how to use any quirk for justice, it'd be Young Midoriya."

"Hoo boy, imagine if Nana were alive and she saw this," Gran Torino said, "I wonder what her reaction would have been."

Meanwhile, All For One was watching things as they played out, keeping silent as he thought about what all he was seeing. The silence from All For One was of some concern to Shigaraki, who turned to face him. "...Sensei?"

"So Izuku," Uraraka began, "You still have Monoma's quirk, right? Will you return it?"

"Actually I can't," Izuku replied in an embarrassed tone, "You see, shortly after Monoma fell over onto the ground face down and laid there as his clothes exploded off of him, his ass blew up a few seconds later. Monoma's ass exploded so violently that he died."

"I DIED?!" Monoma in the audience exclaimed indignantly as most of the 1-A and 1-B students all began laughing their asses off.

"Because your ass blew up!" Bakugo cheered in clear amusement, "That's what you get for taking our quirks, fucker!"

"I did discover something interesting about Monoma's quirk, though," Izuku said, "Apparently, if I use it to copy someone's quirk, I can give that copy of the quirk to someone with my true quirk. Also, copied quirks given out in this fashion don't disappear, they become permanent, solid parts of the people they're given to."

"That's pretty kickass," Kyoka said, "Have you done anything with that so far?"

Izuku nodded a few times in the affirmative. "I did, yes. However, I'm pretty sure that Mirko won't be too happy with what I did..."

"What did he do?" Mirko in the audience said, her tone suspicious over what the Izuku in the currently playing realm could have done.

"Well watch and find out," Ryukyu replied.

...

Mirko was at her home, enjoying a nice mug of coffee. After setting her mug down, Mirko heard a loud roar outside of her house. "...The hell?" Mirko said as she got up to go outside and see just what it was that was making that noise.

Stepping outside, Mirko looked up into the sky and saw at least a dozen dragons flying above her house, flying around and roaring out loud. Mirko sighed to herself as she said, "Well it's a good thing that I had played all that Skyrim." Mirko went back into her house, closing the door behind her for a bit.

A few moments later, Mirko came back out, wearing a full set of Skyrim Iron Armor and carrying both an Iron Shield and a Steel Sword. Looking right up at the horde of dragons that were flying over her house, Mirko shouted up at them, "Fus ro dah, bitches!"

FIN

"So Izuku used Monoma's quirk to make copies of Ryukyu's quirk," Sekijiro began in a mildly confused tone, "Then gave out the copies of Ryukyu's quirk, leading to a horde of dragons flying over Mirko's house to bother her."

"And I think that experience in playing a video game will help me deal with the dragon horde," Mirko said, looking similarly as confused.

Shrugging from where he and Tale stood in front of the big theater screen, Kotaro said, "But you have got to admit, what Izuku did in that realm is pretty damn cool."

Nodding in agreement, Tale remarked, "At least Izuku had shown he wouldn't use the All For One quirk to do evil. Screw with Mirko, maybe. But not do evil."

END OF CHAPTER

Author's notes;

Hoo boy, it feels good to be back to this after a while. Anyway, I got a few more chapters in mind for this, so here's hoping that they will be just as amazing. Looking forward to seeing how they'll fare in the long run. Also, shout out to Legomasterlord, who used one of the chapters from my 1-A and 1-B girls story in his 'Summoned to react' story (I gave him the okay to do so).
