Summary
Katsuki didn’t know what happened along the chain of evolution for someone to end up with a quirk that could change human anatomy, but a brief medical exam later, he was trying to wrap his head around the fact that for the next twenty-four hours, he was biologically a woman.
Deku proceeds to show him the advantages. Enthusiastically.

Summary
Every year since high school, something bad has happened right around April 20th that makes Katsuki swear his birthday's cursed. This year, his goddamn boyfriend gets hit with some shitty sex quirk that has him speaking Italian, serenading Katsuki at his window, and carrying roses in his teeth. Worst of all, it's turned Izuku into a goddamn sex fiend, and Katsuki can't keep up. He needs to get to the bottom of it before they fuck each other out of house and home.

Happy birthday, Kacchan!

Summary

Or, in which Izuku gets hit but a quirk that displays his every thought, and Katsuki is the one to view all those scenes...

Summary
“What the hell is going on, man?” Kirishima approaches Katsuki with concern.
Katsuki blurts out: “Got hit by a quirk. Kid clung to me on the street, asked for a picture, I felt some weird shit like a shiver, but I wanted Izuku to see that I can be nice to little kids too, so I sucked it up and didn’t mention anything. But now I keep blurting out everything I think without a filter.”Alternatively: Katsuki gets accidentally hit by a truth-serum quirk right before a mission with Izuku, Kirishima, and Jirou. As if verbalizing every single thought in his head is not enough trouble, there’s also this: he’s in love with Izuku, and won’t be able to keep hiding it for long.

Summary
This time, Katsuki keeps his eyes down, fixated. "That's how I scent."
"That's how—" Izuku breathes in once more, feeling himself slipping down an ugly spiral. He keeps his voice tight, a sham of innocent curiosity. "You've… scented someone else before?"
Or, Izuku struggles to exist entirely. Katsuki teaches him that to live, even as little as he does, is to bleed.

Summary
“Why does it have to be him?” Katsuki blurts out, because really, that’s what he wants to know. “Of all of the fucking people in the world, why does it have to be him?”
“I was confused about it at first too,” Kirishima admits. He sits up a little straighter. “I mean, you guys fucking hated each other for the longest time. You couldn’t even be in the same room together without getting into an argument or breaking a table.” He laughs a little. Katsuki doesn’t understand how any of this is funny. “Then one day, you guys came into work and… you smelled like him. Everything calmed down after that. It was like all of that hatred and tension was just your way of trying to process your feelings for one another. Once you guys finally, uh, talked it out, things got better.”
(In which Katsuki Bakugou is attacked and loses all recollection of his relationship with Izuku and has to learn to fall in love with him all over again. Faced with a hero case involving a serial killer and missing omegas, Katsuki needs to learn to put aside his own prejudice and open himself up to truth.)

[Pro Heroes Dynamight and Deku Chase Narratrix, Only to Be Forced into... One Bed??]
On their third attempt to capture Narratrix, the duo failed again, and were struck by the trope beam.
"Kacchan," Midoriya grunted, racing away with Bakugo slung over his shoulder, one hand pinching his nose to block out the scent. "We got hit with the Omegaverse trope. You’re… an Omega going into heat."
Bakugo, flushed and fevered, managed a furious glare. "WHAT THE HELL IS THAT, AND WHY DO YOU KNOW THAT, YOU DAMN NERD?!"

Summary
Katsuki was certain his feelings were unrequited and the closest he'd get to being something to Izuku was being his rut helper (buddy?? he didn't know the right word, he was really just there for emotional support). That is until Izuku gets a particularly odd rut, and he finds himself questioning his secondary gender.

Or, Katsuki's a normal beta, Izuku's a normal alpha, that is until he helps Izuku through an unusual rut and discovers something new about himself.

Summary
Why does Katsuki hate it when people present?
Because people don’t know what the fuck they’re doing.
Sure, he can control himself—but he can’t control a newly presented alpha accidentally letting off the full brunt of their pheromones and scent and borderline sending him into heat.
Which is exactly what Izuku has been doing.
Or; Izuku's secondary gender only presented when he hit twenty, which means he's still learning how much of his scent is acceptable to let out in every day life. Katsuki has a very, very slippery time with it all. -

Summary
Izuku wouldn’t call him weak or incapable because he presented as an omega. He wouldn’t manhandle him or push him into the bed and use him until he’s satisfied, like a toy. Wouldn’t intimidate him with his scent, mark him all over, claim ownership over him and leave him feeling disgusting, less like a person and more like an object to be desired and possessed.
Izuku is Izuku. And that’s why Katsuki lets himself do this, just this once.
“You’ll help me, yeah?” His breath is hot against Izuku’s ear as he presses his nose to the underside of his jaw, seeking out his scent, that summery freshness that makes his chest constrict longingly. “You can do that much, can’t you, Deku?”
Katsuki takes some time off training with all intentions of riding his heat out alone.
The only problem: Izuku's in his room.

Summary
“For fuck’s sake, why do people think we’re a couple?” Katsuki’s arm does not move from its resting place around the curl of the other’s shoulders, causing emerald locks to shift closer and tickle the side of his neck. “That’s a weird thought, isn’t it?”
“It is,” Deku agrees, voice muffled from its snug position under Katsuki’s chin. Fingers tighten around the cotton on Katsuki’s back.
“We’re not like that at all.”
(In which Class 2-A becomes the long-suffering, unwilling witness to Bakugou Katsuki and Midoriya Izuku’s not-relationship.
Katsuki doesn’t get it.)

Summary
And don’t even get him started on Izuku.
Because if there’s one alpha on this planet who seems hellbent on dragging Katsuki into the pheromonal fuckfest he wants nothing to do with, it’s that curly-haired, over-eager, green tea-scented menace.
Or; Katsuki is a beta just trying to live his life in a world full of alphas and omegas. One alpha makes that hard. (And even harder when a mission's safe house happens).

Summary
“What’s the line, Shoto?” Katsuki asks, pressing. He needs it defined, needs it solid. “Where’s the boundary? Is it kissing deeply? Is it under the clothes? Where do we stop?”
Another long pause. He can almost hear Shoto thinking, can picture the slight frown, the distant look in his stupid eyes.
“The line,” Shoto says slowly, “is anything that would damage our working relationship after this ends. Anything that would make it impossible for us to be partners when we walk away. That’s the only boundary that matters.”
So it's not a physical boundary. It’s an emotional one. Feelings. And that's so much more dangerous.
OR:
The mission is simple: fake date convincingly, secure the asset. Nobody mentioned the part where "convincing" means letting Todoroki fucking Shoto suck love bites into his neck. Katsuki will be filing a complaint.Series

Summary
Katsuki’s first encounter with his own hanahaki came right at the end of their 2nd year at UA, and as he stands over the ceramic sink, he thinks "Of course the petals are green. What else could they have fucking been."
Green, like his hair. Green, like his eyes. That shitty ner-
"Kacchan?" The devil in question peeked his head through the bathroom door, voice laced with concern, "Is everything okay?"
Of course it's not, Katsuki thinks. But ultimately, all he could do was nod, "I'm fine."OR: Deku and Ground Zero are now Pro-Heroes, 2 years in the industry going strong, but how long can Katsuki ignore the flowers he's coughing up before it's too late. How long can Izuku pine after the former silently until it's too late?
