Crossover Idea #6 - My Hero Academia and Katekyo Hitman Reborn!

Izuku and Bakugou end up reincarnating into the KHR world

Okay, so, the funny thing about me is that even if I’m not overly familiar with a fandom, I WILL read fanfictions from that fandom so long as they’re a crossover with a series that I AM familiar with.  And I’ve been reading a lot of KHR/BNHA fanfics lately because of that, and have thus become passingly familiar with Izuku/Deku (precious green bean who is also swole AF because crazy training regimen) and Bakugou (resident jerk who probably has major self-esteem issues hidden under that explosive shell).  

I have also read enough of that particular crossover to notice that whenever reincarnation or interdimensional travel happens, it’s usually the KHR cast ending up in the BHNA world and not the other way around.  Though those fanfictions I HAVE read that dance to that tune are awesome, there’s some missed potential for chaos there. Thus this dumpster fire of an idea: what might happen if members of the BHNA cast ended up in the KHR world?  

And of course, since they are the characters I am most familiar with in terms of personality at this point, my brain suggested I make Izuku and Bakugou suffer by having them be the victims of my crazy brainstorming.  Sorry, Deku, you don’t deserve this.  (Bakugou, on the other hand, definitely deserves a bit of suffering.)

So, here’re some ideas for this crossover.  Again, I must reiterate, I am not overly familiar with BHNA’s plot, even if I am now somewhat familiar with the two main(ish?) character’s personalities and such, so these ideas will lean heavily towards the whole KHR side of things and not the BNHA side of things, and I might get some details wrong.

Izuku and Bakugou are both Pro-Heroes when the stories start, having long finished school at U.A.  I’ve seen posts about their relationship improving later on in the manga… barely… and I’m a sucker for the jock-and-nerd-friendship vibe of their relationship in fanfics anyway, so let’s say they were slowly but surely ending up friendly rivals again instead of whatever toxic dumpster fire they were before okay

Anyway, long story short some group of villains gets lucky and somehow manages to kill both of them while they’re on duty. Both Heroes are then reborn into the KHR world to the local equivalent of their parents from their last world.

Izuku’s mom is still Inko, but instead of being a civilian single mother Inko is actually the wife of the spare heir of a yakuza family who attempted a coup and failed badly, and is therefore under watch all the time.

The Bakugous, on the other hand, are also related to Yakuza through “Kaachan’s” mom, but they’re not directly involved with yakuza-type stuff anymore because they live in Namimori and as such are kept under watch by the Hibari family.

Inko is still friends with the Bakugous, but because she’s kept under firm watch by her husband’s family she hasn’t been able to take Izuku to visit them, and Izuku’s smart enough to realize that asking about them would probably get his mom in trouble, so he never brings it up despite REALLY wanting to see if Bakugou’s around too.

Izuku’s life is sort of normal apart from the “heir to a yakuza family” thing up until he’s like eight years old, at which point one of the other heirs to the family takes over and decides he wants to get rid of the spare heir and his mother so that nobody else has claims to the family. Inko ends up dead, (sorry Deku) and Izuku ends up going Flame Active as a Sky with strong secondary Lightning Flames.

Izuku ends up making a break for it after his mother’s death, and remembering what his mom said about the Bakugous makes a beeline for Namimori.

Bakugou, on the other hand, while all this has been going down, has actually been living a pretty good second childhood despite the lack of Midoriyas around.  Namimori’s pretty peaceful most of the time despite the number of Flame Actives and former mafioso and stuff living there.  Still, Katsuki was bored out of his mind for like the first five years of his life because after years upon years of fighting criminals and villains such a normal civilian life is just plain BORING to him.

This boredom eventually leads to him going kinda vigilante once he’s trained himself back up to snuff (as much as you can when you don’t have a Quirk anymore, which he’s pissy about), but since he’s still a little kid in a town full of criminals that’s pretty dangerous.  Eventually, though, some stupid assassin tries to off a little kid in town, Katsuki tries to stop him, he nearly dies, and then boom, Dying Will Flames activated.

Honestly, I was torn between having Bakugou be a Storm, a Cloud, or a Sky, because all those Flame types kinda fit him based on what I know of him from canon, but eventually, I decided the best thing ever to do here was make Bakugou have Wrath Flames because those are the closest the KHR world has to his Explosion Quirk, plus having him run around as a mini blonde Xanxus screaming DIE at everyone that pisses him off would give the mafioso glorious conniptions and probably make the Varia go WTF and it would be amazing

Seriously though, Bakugou and Xanxus are incredibly similar.  They both have similar anger issues, they both have similar power sets even without Kaachan having Wrath Flames, they both have similar verbal tics (“trash,” “extras,” all the cussing), heck they’ve even got similar physical appearances, what with red eyes, spiky hair, and both refusing to wear uniforms correctly (i.e. not actually giving a damn about fashion most of the time haha). Bakugou’s basically just a mini blonde Xanxus who decided to go into Hero work instead of Mafia work.

Huh, maybe I should make the two of them related or something.  I mean it’s not like we actually know much about Xanxus’s actual blood relatives, right?  Besides then we’d be able to make the Mafioso have yet MORE conniptions because “oh no all of Xaxnus’s being Xanxus is hereditary.”  

Anyway yeah Katsuki gets Wrath Flames, which he is delighted about because he’s basically gotten his Quirk back, and since he is who he is he’s not at all subtle about having those Flames either, which means he’s basically blowing shit up all over the place as soon as he figures out how.  This eventually results in Hibari – as in the one we know from canon – trying to bite him to death because he’s “disturbing the peace” or something and somehow one thing follows another and the two of them end up sparring a lot and hey would you look at that, Katsuki’s made a friend just as violent as he is for once.

During this period of time Bakugou also properly meets Tsuna, who was the kid the assassin that made him go Active was after, and though at first he doesn’t want anything to do with the kid (“he’s more useless than Deku was at that age, damn”) he eventually sort of ends up beating up the kid’s bullies when they’re off school grounds, mostly just because he can (and because he won’t admit that the kid reminds him a lot of Deku and definitely won’t admit he’s got a bit of a soft spot for people like that)

Eventually, though, the thing with Izuku’s family happens and the green bean stumbles into Namimori.  Some of the local thugs try to beat him up only to get pummeled by Lightning-enhanced fists, and then Katsuki turns up partway through the beatdown and yay, they’re finally actually reunited in this shit world, they’re not alone.

Bakugou ends up bringing Deku home with him and Deku basically refuses to leave and just kinda clings to him for long enough that Bakumom and Bakudad just throw their hands up and adopt the kid. He’s Inko’s kid anyway, it wouldn’t be right to leave him with a stranger, and having someone as sweet as him will help keep their son out of trouble, right?  (WRONG)

After Izuku turns up in town and things settle down a bit he proves he’s just as “crazy” as his new brother/best friend by being just as crazy about fighting as Kaachan is.  Hibari dubs him an omnivore after the first time he picks a fight with the shockingly swole green cherub and Izuku joins Katsuki in the whole vigilante thing they got going on

Also, Izuku kinda adopts Tsuna as a little brother of sorts, because he sees the same things that Katsuki did with the kid stumbling around and all the bullying happening, only instead of leaving it be other than beating up the bullies like Bakugou does he actually goes so far as to actively help the kid out, and ends up dragging Bakugou into the whole thing too.

So basically by the time Reborn arrives in Namimori Tsuna’s got two friends that will literally punch anybody who messes with him in the face, and also who are two former superheroes who do NOT approve of their little brother figure being forced into the mafia like this.  From then on a lot of canon events get de-railed because Katsuki and Tsuna are both playing a game of keep-away to keep Tsuna away from Reborn (or at least trying to, they’re still little kids at this point and he’s the World’s Strongest Hitman, so they’re giving him less trouble than they think they should).

Also when the Varia eventually roll into town Katsuki and Izuku are literally having none of that shit.  None.  Also this is when the Varia see that Katsuki is basically a mini blonde Xanxus and have their WTF moments galore, Xanxus included.  They’re not the only ones, nobody on Tsuna’s side of things was expecting a second Bakugou to turn up out of the blue.  (Tsuna: “Oh my god, oh my god, Katsuki-nii, there’s two of you!”  Bakugou: “Shut the hell up.”)

And that’s literally everything I have on the idea.  I love this idea a LOT, seriously, SOMEONE needs to write something like this even if I don’t.
