Boku no Hero Academia (with a reference from Bungou Stray Dogs)

Story Type: Crack fic, Semi-Canon Compliant!BNHA, Healing Quirk!Deku (but with a twist), OOC!Characters

Now if any of you have read or seen Bungou stray Dogs, then you'd be familiar with the sadistic doctor herself Yosano Akiko. Basically, she has the ability to completely heal all external wounds, no matter the damage. The catch? Her patient(s) have to be on death's door in order for her ability to activate, so most of the time, she butchers their bodies in order to heal them to full health afterwards.

You know those stories where Izuku develops some form of healing quirk? I remember reading a fic or two about Izuku being able to heal people, but there's a huge drawback to his power like he takes those injuries onto himself or something. Well, what if instead of his Quirk needing to cause him pain in order to activate, Izuku has to be the one to cause his patients pain. But don't worry, he's still that adorable mumblestorm of a cinnamon roll who desperately wants to be a hero someday. All Might is still is #1 idol, but next to him is Recovery Girl for obvious reasons.

My headcanon is for BNHA is that a person's Quirk, depending what type, also influences their personality in some way, like Bakugou being so hot-headed and destructive due to his Explosion Quirk and Iida being strict and straightforward because his Engine's acceleration doesn't allow him to change directions quickly. Therefore going by that logic, why not give our sweet summer child a hidden sadistic side that only pops up whenever he sees someone he absolutely needs to heal. (I'm looking at you, All Might… Aizawa too, especially after the USJ Arc. Hell, why not make the Sludge Villain incident traumatizing for Bakugou by having Izuku "insisting" that he needs his "tender loving care" afterwards~? )Think about how HORRIFIED everyone's faces would be once they see that side of Izuku.

He even carries around an oversized first-aid kit, but instead of medicine, bandages, and whatnot, he's got knives of every size and even moar pointy objects instead.

Izuku stared blankly at the deflated figure of All Might. Immediately, his mind worked furiously as he diagnosed any and all possible ailments and conditions that may have caused his hero to become this way. Technically, he's not a licensed doctor, but he did have plenty of practice treating people and himself with his unique Quirk. Tuberculosis, cancer… Come to think of it, All Might had gone on a short hiatus without a single explanation a few years back. Could it be that-?

"Um… Kid? Are you okay? You're kinda scaring me there with all that muttering you're doing," Toshinori said as the teen squeaked and stopped his bad habit. This is a new. Up until now, no one else reacted this way, except maybe Recovery Girl and Nedzu.

"I… That is… C-C-Can...CANIHEALYOUWITHMYQUIRK?!" Izuku blurted out.

"...What?"

"C-Can I heal you? I have a healing Quirk… but it's… it's a bit complicated so I need your permission to use it on you."

"A healing Quirk? That's pretty special since there's not a lot of people with that sort of ability. And you're sure that it can fix something like this? I've had countless of doctors and specialists take a look at me, and this is the best they can do just to save my life but barely."

"I can." Izuku replied confidently. "My Quirk can regenerate your missing organs, even heal up the scar tissue enough so that it'll look like it never happen. However, the new organs might be a little bit sensitive, especially your stomach. You might need to be on a liquid diet for about a week or so in order to get your new stomach used to accepting solid foods again."

"Well, I suppose it can't hurt to give it a shot. However, don't be too discouraged if it fails. Even Recovery Girl had a difficult time trying to keep me alive long enough during my surgeries." Toshinori said to the boy. "Is there anything you need me to do in order for your Quirk to activate?"

Isuku shook his head and replied. "Um…Not really. But you might want to lie down and let me do everything. Also, please take off your shirt while you're at it, that'll be great. It's just so the blood wouldn't get everywhere."

Well, that's fine by- Wait, blood? What did he mean by blood?

Izuku reached into his yellow backpack and pulled out what looks like a large first-aid kit. When he opened it up, Toshinori expected to see it filled with bandages, gauzes, and medication. But instead he ended up spewing up blood in shock at all the amount of sharp items like scalpels and swiss army knives in the innocent-looking box.

"The thing about my Quirk… It's called Momento Mori…In order to activate it, you need to be mortally wounded in the first place. Now prepare yourself… And don't be afraid to scream, I've read that it helps with the pain tolerance," Izuku explained as he took out a portable circular saw from his kit and held it up with an innocent smile and shadowed green eyes.

A few hours later, Toshinori witnessed Izuku doing the same "procedure" to his childhood friend in an abandoned alleyway only with an oversized machete straight out of a Jason Voorhees movie.

As the newly healed Bakugou shuffled out and was about to head straight home, Toshinori took the opportunity to lay a comforting hand on the boy's shoulder.

"Do not worry, young man. His methods may not have been… tasteful. But he did heal you to full health."

Bakugou stared up at the hero with dull eyes. "Let me guess, that little bastard got to you too? You most likely don't know this, but I've known Deku since we were still in diapers. And as a result… I was his first fucking patient and have been ever since."

AN: I am currently head-over-heels in love with BNHA. So I wrote this segment just to get my writing mojo back.
