If there ever was a yandere going after one of the (hero) characters in MHA the only way they'd succeed is if they didn't kill or kidnap anyone, or if the character was a yandere too and it was a mutual thing.
If Bakugo ever joined the LOV (meta liberation army in s6) Deku wouldn't join and instead he'd have a similar relationship with Bakugo that Sasuke and Naruto had. Where Deku would constantly chase after Bakugo as he's achieving his dream.
Bakugo and Mina sometimes read eachothers manga.
Denki and Jirou end up together. Once they become pros they promise not to go on hard missions unless it's absolutely necessary. They'd probably also try to stay out of the top 10 so they wouldn't be forced on dangerous missions.
Class 1A and 1B bet on Bakugo's hero name and none of them got it right.
Deku and Bakugo wouldn't retire unless they were absolutely forced to. Deku would do volunteer work almost all the time once retired.
Most of the interviews with Deku are left unfinished due to him having so much work Once he goes pro.
Mineta eventually acts mature and gets a girlfriend who lives outside of Japan and everytime he tells his friends they'll be like. "Right, is she from Canada?" Until they actually meet her.
After Eri uses her quirk too much on Mirio or Deku as they grow they soon begin to be noticeably a bit younger then their peers.
If Eri become a hero during her time at UA she'll internship with Deku or Mirio (most likely mirio)
If Deku has his own agency he'll make dorm rooms for other hero's to stay if they want. (He'd also stay in the dorms)
Deku makes sure to visit his mom every week
Bakugo would smell sweet when he rescues people and eventually high end brands would try to make a cologne similar to it. They would do the same with midnight but no one can remember what it smells like bc they pass out.
Mina, Ochaco, Bakugo, Deku, and Todoroki choose not to have a love life due to either being on the aromantic spectrum and/or the dangers of being a hero. So they'd try to stay single
If Toga became a hero she'd definitely be an underground one. Her quirk would be perfect for stealth missions and she's pretty damn skilled with a knife.
Aizawa definitely comes to school covered in cat hair. Everyone's just gotten used to it at this point.
Monama never rid of his ego he just eventually learns to stfu.
Once the public finds out about Endeavors abuse he goes back down to #2 hero and stays stagnant with that ranking. His mental health eventually starts steadily decreasing. (Boutta go join Rei in the hospital)
After Dabi's dance Touya visits endeavor every night as he sleeps to torment him unless he's super busy.
Shoto has to go to therapy after this shit.
Deku never felt any type of way about the scars on his arms until he gets ask about it a lot and becomes self conscious. Kirishima helps him out of this mindset.
Ochaco eventually gets a baggier shirt for her hero costume that has a band on the bottom so it won't fly up when she floats.
The most popular hero for kiss is froppy.
Someone pours flour onto Hagakure as an April fools prank (Denki) and they get a basic idea of what she looks like so eventually she shows them baby pictures so they get a better idea.
The public tries really hard to figure out what hagakure looks like but are unable too.
That's honestly probably not a piece of DABI'S jaw they found. He's probably wondering who tf's it is. That or he placed it there.
Melissa's "if I go missing" folder just has a note that says "get Deku" and probably an updated list of people who could've done it. (Melissa is from the mha movie Tale of two heroes)
Deku continues to make plans with little regards for him self. Soon someone gets hurt because he got injured and couldn't save them. Then he finally thinks about himself also.
Once Lemillion becomes a pro hero he mainly does rescue missions.
Midnight has closets full of copies of her hero costume so that she always has one ready.
Denki's favorite anime is sailor moon. (Theres no thought behind this other then its funny)
There are mean girls at UA but they're in lower level classes because they just suck at being heroes.
Mei asks Momo for materials for her projects. A LOT.
Denki thought a lot was one word (alot) until Momo finally told him it wasn't.
Class 1A is like one big family so they go into eachothers rooms unannounced sometimes.
Bakugo lights things on fire to dispose of them sometimes. (By things I mean paper)
Todoroki read weird fan mail about fanfictions and looked it up.
Deku makes sure to read all his emails and letters from people. He tries to reply to as many fan ones as possible but uses his hate mail as self improvement.
Todoroki gets mail from a fan in Canada saying "your hair looks like our flag" and he replies "It doesnt have a maple leaf on it though?"
Deku stops keeping notebooks about heroes and quirks and instead keeps a highly secure tablet to use as a note book. The hero commission/government would eventually try to take it for their own gain and to hopefully take down any heroes who don't follow their standard. They fail.
