Okay but what if Ms. Joke has the world’s largest reserve of the most absolutely filthy jokes you can think of stored away in her head for when she’s faced with a target with a particularly dirty sense of humor. She just keeps those for emergencies or when her audience isn’t too young to be hearing those kinda jokes.
She has “clean” versions of all of those jokes stored away as well, of course.
When she and Aizawa met for the first time, during the provincial license exam, he looked at her curiously for a second before asking what her quirk was,
“I make people laugh!”
“Tch, useless on me then.”
He had suffered at hands of Mic’s relentless puns and generally “so bad it’s good” jokes for the better part of a school year at this point, he’s half way convinced he can’t laugh at all.
Emi looked at him blankly for a second, blinked twice, then the most horrifying grin Aizawa had ever seen, before or since, stretched across her face, “That a fact?”
Shouta quickly figured he may or may not have made a horrible mistake.
During the first round, he couldn’t find her anywhere, his paranoia nearly getting him disqualified a few times if not for Mic.
In the second round is where she strikes, and she does it so subtly, that even the future Eraser head could never had seen it coming.
She runs past him on route to her objective, and as she comes near she leans into his ear to whisper the best, or worst depending on who you ask, joke in her dirty arsenal to Aizawa before he has a chance to even realize she did it.
She moves on, leaving behind a collapsing Aizawa Shouta to crumple to the floor, holding his gut as he laughs loud enough to be heard all around the exam grounds.
(He doesn’t pass that year, obvisouly.)
Aizawa has been on high alert around her ever since, while she’s determined to get another laugh out of him.
Hizashi has begged up and down multiple times over the years for Emi to tell him what joke she used on Shouta, but she only winks and says that it’s, “A secret between lovers~” Aizawa shudders every time she says it.
Bonus: She once got caught up in a major villain attack while in her civilian clothes, she managed to save the day by walking up to the group of criminals, all with a type of “giant” quirk and pretty mean looking over all, and managed to beat them by telling her personal version of “The Aristocrats” bit. Which is 30 minutes long.
By the time more heroes showed up to take the villains into custody, the lot of them were curled up into a fetal position. All videos of it vanish from the internet in under an hour.
She considers it one of her personal favorite achievement of her career as a pro hero.
“Well,” She tells the news channel that’s interviewing her with a cheeky grin, “That and making Eraserhead pee his pants using a dick joke.”
Joke would make it her mission in life to make Eri laugh at least one or twice a day. One look at her forlorn face was enough to send every single one of her “sad child in need of laughter” reflexes (that she had honed over the many years she served as a pro hero) on overdrive.
Then she saw a picture of her blinding smile during the culture festival and decided that a girl with a smile like that had no buisness being sad at for any reason whatsoever.
She’s so focused on her self imposed mission that she completely forgot her other minor goal in life, that is to make Aizawa “Eraserhead” Shouta actually chuckle at least once more (the first time is one of her personal favorite achievements of her career), to which Aizawa is thankful.
Eri’s proximity to himself as forced him to be in the immediate blasting zone of Joke’s full force efforts and have started to get dangerously close to making him laugh, an indignity he isn’t sure he could survive.
…But, he supposes it is a small price to pay for all the times she had managed to drag even the tiniest giggle out of the child under his care.
(Eri caught wind of him chuckling to himself once after one of Joke’s “Assaults”, and look she gave him almost convinced Aizawa to actually allow himself to laugh when Emi (God when did he start calling her Emi?) comes back to try again. Almost.)
Headcannon that Ms. Joke doesn’t just call her students “My kids”, she treats them like they are actually her own kids.
Like, giving her students great big hugs whenever they make a significant improvement in using their quirks, absolutely gushing and marveling at each and every one of them when they show off a special move (”Hey Mo-I mean Ms. Joke look at this!” is a rather common saying in her class, she pretends not to notice but it makes her day every time), packing a few extra sandwiches in case someone forgot to bring their lunch and don’t have enough money to pay for one.
And visiting any students that didn’t come to class that day to make sure their okay, bringing along all the homework for that day and like, twenty different unbelievably bad puns to cheer them up.
Also NOBODY bullies her kids, because the last student who did that had a…talk with her. When they came back they were pale as a sheet and kept muttering, “That wasn’t funny…”
(when people found out exactly what she did she nearly lost her job, but she doesn’t regret it, not one bit,
“Nobody messes with my kids,” She told the principle of Ketsubutsu when he asked why she did it, “Nobody.”)
…I just really like the fact she calls them her “kids” okay!?
Oooh, this is good. Protective teachers are my favorites (glancing over at Toshinori and Aizawa here).
In return, the kids adore Ms Jokes. She’s the funny mother-figure of the whole class.
YES, protective and supportive teachers are the best!
Also, I’m pretty sure that if she didn’t think it would distract them she would have been waving a way-to-huge banner that read, “GO GET’EM KIDS!!!” in great big letters while cheering them on at the top of her lungs.
…along side Aizawa, who is calmy waving a much more reasonably sized flag that reads “Go class 1-A!” that she gave him as a joke without expecting him to actually use it, “Yeah, what she said…”
