Summary
“Why the hell are you only asking me this shit now? You-”
“Because I-” Bakugou tries to respond, but gets cut off.
“Rhetorical question, let me fucking finish or I will gut your intestines out here and now.” Izuku breathes, just for a second. “You have done nothing to deserve any explanation from me, and if this is your form of some shit apology only your egotistical hide could produce, then you can take the stick shoved up your ass and shoot it through your own skull.
“We are done here. Don’t ever talk to me again.”
Izuku doesn’t know how to process having his dreams shattered.
So he runs away. It’s too late for apologies, now.

Summary
Are the actors in a play fulfilling their roles for fame, fortune, or fun?
In a play, there's usually one protagonist, one antagonist, and a few side and supporting roles. It's simple, only a few scenes and plots to observe. But that's not real life, where everyone is a main character in their own play. Can that really be called a 'play', when it's not playing pretend?
Shihai Kuroiro, resident schemer of Class 1-B thought himself a main character until over 20 of his classmates received people from another world. And that made him think… "Will I ever get one?"
William Blake never thought he'd end up dead; but now here he is, in the same body as Shihai, forever changing the role both of them will play.
But how will this world of changing actors and growing cast affect the two of them?
…Will Shihai and William really stay unaffected by the growing number of other Self-Inserts disappearing?
Well, to answer our original question, this 'stage' can't really be called a stage when it's real life, can it?

So now, in the Apocalypse, Katsuki finds himself with a few stray Quirks and a Noumu Kirishima to take care of.
He's not sure how they'll survive, but no matter what form he'll take, Kirishima will always be his Shitty Hair.

A very much not-small problem by Dark Aster (Casterisk)

Summary
Izuku has a bit of a problem.
You see, whenever Todoroki is around him, it affects Izuku. He’s been nursing this infatuation he’s had for his friend for a good year and a half now, but because Todoroki is so stoic and cannot take a hint, Izuku doesn't know how to open up to him.
But when Izuku gets hit with a quirk that only allows him to eat semen, the problem ends up being confronted a lot sooner than he thought.
However, it turns out Todoroki is much more enthusiastic than Izuku could conceive, and his mouth can stretch much wider than what he thought was possible.
...
TLDR: Midoriya is hit with a cum-eating quirk and Todoroki has a very big dick. Shenanigans ensue.

What Good Boys Get in the Gym by writtenbymondays

Summary
Bakugou and Midoriya are supposed to be training. Instead, they lock themselves in the school gym and fuck like animals on a yoga mat. Loud, messy, and completely unbothered by the fact that Class 3-A can hear every slap, moan, and broken sob echoing through the halls. They don’t care. If anything, they want the whole school to know. This is just round one out of many. The fallout is someone else’s problem.
Note:
Main Story Chapter 1 to 26 (Completed)
Bonus Chapter(s) 27 to ? (Ongoing)A/N: I have finally decided to mark this as incomplete because man, as I've been rambling for far too many chapters already, this fic was already out of my control and has become a sentient beast that writes itself. I'm so sorry for the previous false advertisement. Thank you for not giving up on this. :)

Summary
A world with no Dursleys was a world Harry Potter was bound and determined to stay in. To do that, Harry Potter wanted to be great. To have every opportunity the wizarding world could offer. So, he used the Restricted Section. He learned. He studied with Hermione, made friends, and did his best to have a normal, happy childhood. Anything so he would never have to go back.
But when a troll was released his first year, when he was betrayed in the Chamber of Secrets by Lockhart, and when every adult in his life failed him, that was when Harry and his friends knew the adults couldn't be trusted. They'd been burned one too many times. Then, when Voldemort returned, they had no reason to believe that would change. Harry and his friends would survive.
History was filled with great wizards of distinct moral alignment: Voldemort, Grindelwald, Herpo the Foul; even Merlin walked a dubious line. No one with purely good intentions would expand their power so outrageously. Harry hoped he could be the first. Because he knew if he was going to stop Voldemort and protect his friends, he needed to inherit that legacy of power.
Harry Potter was hungry for control.

Summary
You've seen it. A fic formatted like a classified document. A chapter that looks like a real social media feed. An interactive game, somehow, inside an AO3 work. You clicked the kudos button. You thought: how.
This is the tutorial that answers that.
A beginner-friendly guide to HTML and CSS on AO3 — no prior coding experience required. By the end of this series, you'll know enough to write formatted fics, build your own workskins, style your entire AO3 interface, and maybe make something that makes other people stop and think how.

Summary
When Sitri dies, Rhea can only save one of her children. Five years later, the second twin wakes up. Instead of returning the child to Jeralt, Rhea decides to raise the child as her own. But all roads lead to Rome, despite the journeys taken along the way.

This was supposed to be the "what if" side story to the rest of this series but has since spiraled out of control and taken over my mind in this fandom. (no context necessary... because of the spiraling out of control)
