HERO!! by Crude_Mood
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)

Summary
After his fated battle with All for One, All Might is left with a brand new child- congratulations, It's a boy!
All Might's going to learn to come to terms with raising a child and learning how to live for both himself and Izuku- a difficult feat considering he's lived his life solely for others. Little did he know this boy would end up giving him the thing he's always craved- family.
And Izuku? Well, he's just going to have to learn what it means to be surrounded by love and safety. All Might being there is a great bonus, but they both have a lot of trauma to unpack that can't be punched away; sometimes you just have to talk it out.

Summary
The cab's door closed with a soft *thud*.
Cross looked at the rear-view mirror, more professional than fully turning around to see the person he'd be driving around. He was just that, professional.
Or at least he tried to be, he hadn't been working as a taxi driver for very long, actually, but it was a nice enough job. The pay was good, even if the company that hired him was less than desirable. He'd climb his way up from there in due time.
Besides, the service was plenty when the city was so full of life.
Not this part, specifically. This part was nearly desolate, industrial estate thirty minutes away from it, no one in sight... except for the man that he had in his back seat.
Or,
Cross is an overworked taxi driver, too overworked to really judge the weird guy that keeps on requesting rides from random location to random location. He pays well, and Cross really just wants to get by. He knows nothing of the other, other than how nice he is to talk to, in the sea of tourists he has to drive around.

Summary
“That’s… not good,” Skull remarked, as he eyed the gloved appendage and all the glitches swarming it, in their full glory.
Or, the one where the cat's out of the bag, and Soot has to deal with the effects of the anti-void. Skull's there, though.

Summary
The avian cocks his head, in that weird way they do. It seems very unnatural and almost painful, but he knows it isn’t.
“Are you fish really this territorial?”
“I’m not a fish, I’m a mer!”
Reaper chuckles, as if he’d expected nothing less. “Yes, yes, I can see that. Why are you so protective of this place, though? Do you do this with everyone, or do you just not like me?”
