The Office of Vulgar Quirk Affairs has an assignment for you...
Some quirks are, for lack of a better word, vulgar. That is, they are generally considered offensive in and of themselves. They may be related to bodily functions that most people agree are disgusting. Or they may be related to carnal activities that most people agree are inappropriate for public display. Or they may even be related to speech or other expressions that most people agree are distasteful. It should come as no surprise, then, that people with vulgar quirks face significant societal discrimination. and this is especially true for heteromorphs with vulgar physical mutations.
That's why the Office of Vulgar Quirk Affairs (OVQA) was created. At first, the OVQA's job was to "quarantine" these people, find them places to live and jobs to do where they'd be "out of sight". Nowadays, though, they also provide specialized quirk counseling, quirk-suppressing drugs for those eligible, and many other resources aimed at helping people with vulgar quirks live happy, healthy, productive lives.
For this prompt: You work at the OVQA, and Principal Nezu wants your help.
In a proactive effort to combat quirk prejudice, Principal Nezu wants the OVQA to sponsor a student for UA's new incoming class. The intention is that, if UA and the OVQA can train and promote a student with a vulgar quirk to become a hero, that could be an important step towards turning around public perception. There are, of course, requirements:
The student's quirk. Yes, we're going for vulgar, but this is a kid's show we don't want to stir up too much controversy all at once. A big part of this is going to be finding the right quirk that fits the bill. What's a quirk that's vulgar but that can still be framed or spun as heroic?
The student's psychological profile. They need to be able to deal with bullying, discriminations, and ridicule in a healthy way. UA will, of course, protect the student from their classmates as best they can while they're learning. But protecting the student from their classmates' parents will be more difficult, as well protecting them at internships or work studies. And of course, once the student is working as a Pro Hero, they will be on their own.
Ironically enough, you may need to go with a sexually provocative Quirk for that one. It would be difficult to sell Scatman to the public (Ski-bi dibby dib yo da dub BRAP) or anything to do with urine, someone who needs to swear to create Present Mic-esque shockwaves simply isn't marketable enough if you want to groom children to join the hero market, either as customers or the product (heroes), and anything to do with other bodily fluids may be too unsanitary for people to want to create a cult following around.
Yeah, there's Mina who secretes/sweats acid, but it's a separate bodily function. It's no different from Shoto making fire. Someone who pisses acid though, i.e. unzips his pants, takes out his penis and aims it at the enemy, that's not the sort of guy you would make water bottles of. (I am referencing a very unfortunate Spider-Man water bottle that makes it look like you are felating him.) A sexual quirk would carry the stigma of people assuming you are a slut. BUT, unlike most of the other Quirks listed, it would have some support from the sexual liberation movement, because any criticism towards the Quirk and in extension the person would be seen as regressive and gather the ire of any number of feminist, sexual liberals or LGBTQ+ communities. Of course, it would need to be the "sexy" kind of sexual Quirk. The "I absorb people's strength with kisses" kind, not the "I lasso villains with my hyper-elastic dick" or "I made a trampoline with my vulva so that this people can jump out of that balcony" kind. You could have one of those if you are hinging on comedy to appeal to the public, penis lasso man would definitely have Mr. Satan-esque status in fan communities, but you want to keep things SFW in a highschool environment and Aizawa's drawer has only so much vodka to have to overlook a class where penis lasso man traverses the landscape by slinging around things. Start with tame and marketable kiss-only Rogue (Thought of a hero name: Kiss-and-Tell), criticism towards whom would make the opposition look absurd for criticising, work your way up to the Scatman. (Ski-bi dibby dib yo da dub BRAP.)
Someone could have a quirk like Larcade Dragoneel from Fairy Tail, that the quirk can make anyone feel intense pleasure or urges like hunger or sleep which will decapitate enemies mid fight. This is in between NSFW and SFW to be completely honest, on one hand there's no nudity involved, if you don't know what's the quirk is actually doing you'll think the enemy is just writhing in some sort of physical pain. It does brings the debate if making someone feel good to the point of pain without their consent and without doing any bodily harms is counted as sexual violence??? I mean nobody wants to be punched in the face either right?
The kind of quirk that my mind goes to would be one that requires near constant use of an illicit substance. I'm thinking something like, the person needs to constantly smoke/consume alcohol to function normally and use as heroic power. An approximate example in fiction would be Gin Genie (Marvel Comics), who can create vibrations proportionate to her alcohol intake.
This is a really unique idea, and actually has some legs with its prompt. Unlike most average My Hero Academia fan fiction, which largely focuses on the perspective of the student protagonist learning to be a hero and their school life, this could be from the view of a "You", the sponsor of the student.
It would be interesting to see the business side of managing a prospective hero, and having a relationship with the sponsored hero. some examples that I could think of would be, having to negotiate with marketing teams, manage disgruntled parents, socializing with coworkers, all while being responsible for a teen who they spend most of the day away from.
I actually thought up a quirk that fits that sort of description.
Harmicist: allows the user to take in any form of narcotics while buffing their positive effects and nullifying the negative ones, which can then be afflicted on others with a touch. Basically, take crack and gain super-speed for like an hour and have almost no negatives when It wears off.
I think anything that could be considered "squick" would be excellent for this. I've been toying with the idea of a hero that has to experience body horror (eg: shifting bones, growth of extra limbs) to either stop utilizing their quirk or to get actual usage out of it. i imagine that using it in the case of an emergency would attract a lot negative attention, yeah. but also positive attention, from a few very bad people. would probably go viral.
However, more in line with the described use of vulgar quirk: Skin Shedder: User sheds their skin like a snake. It keeps some of its initial shape - so you know it's from that user, due to the... features... of that shed skin.
in-universe, i think Midnight and Aoyama are peak examples of vulgar quirks. any further is pushing the envelope of what we've seen canonically. that being said, fanfiction is the perfect medium for evaluating what constitutes as a superpower and what counts as an inconvenience or affliction! hero society needs some more fleshing out.
