BNHA/Naruto reincarnation au

Ok ok so the trope is that one character is reincarnated into another world, either as another character or as a new insert in the world right? I had a kind of cracky idea for this one.

It’s a bit long but basically a ton of characters from My Hero die during the War arc and are reincarnated as Naruto characters, which changes canon timeline but not a ton at first because they all think they’re the only one. Like, literally Minato is All Might, Aizawa is Kakashi - Team 7 is Izuku (Naruto - trust me I know it’s weird, but nearly-adult Izuku in a child’s body is here to cause problems on purpose), Bakugou (Sakura - the temper and eventually the ability to smash boulders? Yes. I know Naruto and Sakura could be flipped but I have Reasons), and Todoroki (Sasuke - evil older brother, fire stuff, kinda stoic) - there’s more under the cut because I don’t have the energy to write an actual entire fic but I need to put it down. Maybe at some point I’ll write the rest.

Yagi thought it was a dream for a while. Thought it was a nightmare, some days - but being Namikaze Minato was oddly satisfying in that he earned every bit of his power along the way. He was proud of it, the strength and speed and intellect. The only person he ever told about his old world was Kushina - and she believed him. His heart ached when his team fought and died and fought more - he tried to reach Kakashi in his grief, but the boy wasn’t happy.

Aizawa doesn’t tell a soul that he’s someone else, that he’s a fraud, not a genius. He doesn’t dare make a friend in Obito or Rin, still aching because all he can think is Mic and Oboro and his fucking class all gone. Minato’s sunny smiles in the midst of being a deadly destroyer of armies makes him think of All Might and Izuku, the heroes, the best of them. It hurts when it’s all taken away, and he uses his knowledge of how not to strain eye-related powers to cover his Sharingan when not in use and dives into ANBU to avoid thinking too hard about everything.

Touya aches. He’s a genius of his clan, blew his first fireball so hot that it charred his throat for a week and glowed blue-white instead of red. This world doesn’t leave him burned beyond repair, and killing isn’t what makes a villain - but he still becomes one, for his little brother’s sake, because while Fuyumi, Natsuo, and Shouto are gone, he still has Sasuke. (Another suicide mission fueled by revenge - only this time it’s him that has to die in the end, not his father.) Itachi’s new flames are black, not blue.

Hawks is tired of lies. So tired of being loyal to a system that’s full of false promises. He might be a shark instead of a bird now, but he still flies the coop and joins up with a group that comfortably reminds him of the League.

Izuku grieves everyone - of course he does - in the quiet of his little apartment. He’s reminded again and again of the fact that he’s different for whatever reason. This time, instead of crying, he shouts - he laughs - he pranks the shit out of everyone to just be noticed for something that’s actually under his control. If he can’t be the #1 hero, then dammit he’ll be Hokage - the strongest leader he can manage to be.

Katsuki doesn’t know what the fuck to do. One, he’s become a girl - gender didn’t really matter all that much to him compared to strength and intelligence before, but it was still weird. What frustrated her more was his lack of quirk - explosions had defined Bakugou for so long that frankly, she was still going to research Iwa’s explosion corps and do something about that to add to her repertoire. Somewhere along the line Ino attached to her like the limpet Kirishima and Mina always had - getting up in her personal space without caring one way or another, understanding when she refused to speak, encouraging her temper every once in a while. The one annoying thing is that Ino interpreted her need to get stronger than the current projected Rookie of the Year as a crush. Which - no. Sasuke was objectively good looking for a kid, but he was also intellectually a hell of a lot younger than Katsuki-Sakura, and he always uncomfortably reminded her of Todoroki.

Shouto thrives at first - glad not to be the only one with expectations, even if he winces at the idea of an older brother shouldering so much responsibility. He lives for having an older brother to look up to, to get close to. He’s a little miffed that his clan’s specialty is fire-based, but hey, at least his father doesn’t expect him to be his successor - until he does. Until Itachi starts going on more and more missions, poking his forehead and saying “Another time, little brother,” more and more often. And then the massacre happens, and Sasuke wonders why he ever trusted that things would be so stable and ok. He’s going to get strong, drag Itachi kicking and screaming back to Konoha, and rip his eyes out so he never does that again.

...

Kakashi is late again. Sasuke was more irritable than usual - after Wave, their sensei had promised to help him learn the Ice Release that Haku had done, and he’d really wanted to have that in his arsenal to have something more familiar. Sakura and Naruto had begun sparring in their boredom, and in the middle of it, Naruto slipped and hit one of Sakura’s sore spots from the mission. She snarled.

“Fucking deku, what the hell!” she said.

Naruto yelped and fell forward, following through too far on a punch, eyes wide. Sasuke stared, blinking.

“Interesting,” said Kakashi’s voice behind them. Sasuke was staring at Sakura in shock, and Naruto looked like he was staring at a ghost. Sakura’s cheeks were turning pink.

“What are you looking at me like that for?!” she demanded.

“Problem children,” Kakashi said. All three faces whipped to face him, mouths gaping, eyes wide.

“ . . . Aizawa-sensei?” asked Shouto quietly.

“What?” demanded Bakugou. “All of us? Who the fuck are-Icy-hot? Deku?”

“Kacchan!” Izuku’s expression on Naruto’s features was - well. Kakashi cursed inwardly - had things gone well, fuck, he’d be the kid’s older brother figure. This wouldn’t have gone this far. But the elation of not being alone was too much, even with that sting of he was right in front of me and I did nothing.

“If we’re all back here,” Sasuke said quietly, “Who else might be?”

“Well, this changes things for us, but not for anyone else,” Kakashi explained. “As far as the world knows, we’re the same as we’ve always been. However, you studying Iwa explosion tactics and you wanting to learn ice release jutsus makes a lot more sense now.”

. . .

Gaara had always had it in him to destroy. From dust to sand to death - it was all the same. The Ichibi raging against a jagged seal had only exacerbated an already damaged mind, one that couldn’t handle the empty space where All for One used to be. Instead stood rage.

Yashamaru had helped, for a while. Gaara had almost even considered telling his greatest secret to his siblings - that he was once a terrible monster of a human, Shigaraki - but his uncle’s death shattered that thought quite thoroughly. That was all it took to turn him once again into a monster, until a kid with another tailed beast inside him raged against his pain hard enough to scrape at his most protected secret: He didn’t want to be a monster or a villain.

Naruto had that blinding smile as he fought he’d only seen a few times before - on Midoriya Izuku.

. . .

When Itachi next faced Sasuke, he had expected pain and rage.

Instead, his little brother created a prison of ice mirrors, Sharingan flashing as he finished the sequence of signs. His teammates screamed from outside the dome, and Itachi grimaced as he readied a stance - when had Sasuke learned anything about ice? Why would he -

“You’re going to give me answers, aniki,” he said. “One of which is this: Touya, what the hell?”

Itachi stared. And stared.

“You-Shouto?”

“Apologies for not having the hair dye remover and livestream set up, but yes,” he replied.

. . .

Shikamaru was . . . well. He wasn’t an idiot. Talking about reincarnation and heroes and another life was a way to get a trip to T&I and never leave. It didn’t mean he didn’t use his skills - Aizawa would be proud of how lazy his son had gotten in his next life, he bet.

So when he saw Team Seven act a lot differently at the beginning of the chunin exams than he recalled, he was on high alert to find out what was going on. Naruto had learned some level of volume control, Sakura had tempered whatever her issue with Sasuke was, and Sasuke had - not softened, but definitely cooled off. Seemed more attentive to his teammates.

And Kakashi had certainly become more present, if the way they were presenting themselves with high-quality gear was any indication.

Chunin Exams, Sports Festival - didn’t matter, he was still going to prove himself. No matter the fact he didn’t have his quirk anymore, he still kept asking questions.

“Hey, Sakura. Naruto. Sasuke. You ready for this?”

“We’re going to pass,” Sakura said. “No other option.” He raised a brow.

“You sure about that?”

“Sakura-chan said it, so she means it,” said Naruto. Sasuke nodded.

“What about you and your team?”

“Well, it’d be a drag to take the exam again. Guess I’ve got to get the promotion now,” he sad, sticking his hands in his pockets. “Gotta scope out the competition - I’m not here to make friends.”

All three stiffened, and Naruto’s eyes lit up.

“Shinsou!”

Shikamaru spluttered.

“Wh-what?!”

“You’re not the only one,” said Sakura immediately. “Shoulda figured, eyebags. Would have thought Aizawa would be a Nara too, but it still fits.” Shikamaru was, of course, reeling.

“Aizawa’s here?! Wait, who are you three, then, if you know?”

“I’m Deku,” said Naruto, and yeah, that tracked.

“Who the fuck else?” asked Sakura, and yep, her temper and Bakugou’s were just about the same amount of hair-trigger. Which left -

“And you’re Todoroki,” he said. Sasuke nodded.

“Kakashi’s Aizawa. He’s gonna be really glad that you’re here, Shinsou. Talk to him when you get the chance.”

. . .

“You might be a monster, but so am I,” Naruto insisted as Gaara’s wild gaze turned on him.

“No, no, I was born a monster,” Gaara insisted. “I destroyed everything I touched, it all was decay, I ended a world -”

Oh. Oh.

“And All for One’s gone now,” he said.

The Ichibi’s form flickered, and the sand surrounding the boy flailed whiplike and dangerous.

. . .

Naruto entered the seal and frowned. It - his body, his spirit felt different. Somewhere between Naruto and Izuku. The mindscape shimmered, and a blond figure stepped forward - the First Hokage. But another step forward, and he shifted into someone else equally, no, more familiar. Naruto choked.

“All Might?!” he gasped. “You’re the Fourth? But - how - how is this?” he was helpless for words. Minato stiffened, staring at how the spirit before him shifted back and forth between a young man with whisker marks and blue eyes and a mop of green fluffy hair.

“Izuku? You’re Naruto?” he asked quietly. His son nodded vigorously.

“It seems I’ve bestowed quite the power and burden on you twice over,” he mused. “Come here. It’s not every day a father gets to see his son for the first time in over a decade,” he said, arms open. Naruto blinked.

“My - my father?”

“Yes,” he said with a sad smile. “I only ever told your mother about my past life. She even believed me!”

Izuku-Naruto stumbled forward and sobbed into Minato-Yagi’s shoulder, clutching him tightly.

“It’s not just us,” he said, “Aizawa and Todoroki and Kacchan and Shinsou and - there’s more out there, I’m sure of it. Not everyone, but more. And I’m going to save them all this time.”

Minato smiled.
