Try a dedicated fanfiction subreddit like r/BokunoheroFanfiction. You can post links to your work hosted anywhere, but more importantly, you can pitch your OC's concept in a text post first. Gauge interest, ask for beta readers, and see if your villain's angle resonates. I've found my best beta there—someone who really challenged my OC's motives and made the story twice as good before it ever hit AO3. It turns publishing from a solo act into a community workshop.
I cross-post my MHA villain stuff on both AO3 and Wattpad, but they serve totally different purposes. AO3 is my archive—clean, organized, and where my most plot-heavy, gritty work goes. The feedback is usually more detailed, especially if you tag for 'Graphic Depictions Of Violence' or 'Morally Gray Characters'. Readers come prepared for the dark stuff.
Wattpad feels more social, almost like a serialized drama. The algorithm can push your OC story if you update frequently and use popular MHA tags like '#bnha' or '#villaindeku' (even if your story isn't about him, it gets eyes). My villain OC fic there got way more chapter-by-chapter reactions, emoji comments, and fanart prompts than anywhere else. The downside is the audience skews younger; sometimes they want redemption arcs faster than I'm writing them.
Honestly? I started on Quotev. It sounds old-school, and it is, but there's a tight-knit community for OCs there that I haven't found elsewhere. It’s less about massive traffic and more about building a little circle of writers who trade stories and do collaborative prompts. The interface lets you create quizzes and polls about your OC, which is a fun way to get readers invested in their backstory.
For a villain OC, that slow-burn character investment can be gold. I posted a multi-chapter fic exploring a villain's descent after a failed UA exam, and the readers who stuck with it were incredibly loyal, theorizing in the comments every week. It never would have been discovered on a bigger site, but the quality of interaction was higher for me. Sometimes the best place isn't the biggest, but the one where your specific niche huddles together.
So you've crafted an MHA villain OC and you're ready to throw them into the fray? I totally get the struggle of finding the right spot. My own chaotic neutral 'Bloodwrath' character spent ages in my drafts because I couldn't decide.
AO3 is, hands down, the most welcoming space for darker or morally ambiguous OCs in the 'My Hero Academia' fandom. The tagging system is a lifesaver—you can flag for 'OC-Centric' and 'Villain POV' so the right readers find it. The culture there is more receptive to complex, non-canon characters exploring the underbelly of hero society compared to some other platforms. I've seen fantastic villain-centric works there that dive into Stain's ideology or the Meta Liberation Army's politics, and readers genuinely engage with the philosophical questions.
FF.net might still have a bigger overall MHA archive, but in my experience, OCs—especially villains—tend to get buried unless they're tied to a popular ship. The review culture can be hit or miss, sometimes skewing toward less constructive feedback on original characters. Still, it's worth a cross-post for exposure if you don't mind sifting through more generic comments.
Don't overlook niche spaces like specific MHA-focused Discord servers or even Tumblr blogs dedicated to OC worldbuilding. The audience is smaller, but the conversations can be incredibly deep and rewarding, perfect for fleshing out your villain's motivations with other fans.

Obsessed with werewolf novels? So was Natalie Stewart, a typical 25 year old freelancing artist who spent majority of her spare time reading trashy werewolf books online. Over the years, she’d come across countless styles and variations of the classic tropes, enjoying every twist, heartbreak and steamy matebond moment the female leads would go through.
But as Natalie unfortunately meets an untimely death, dying in her very own kitchen during a home invasion, the last thing she expected was to wake up inside the body of someone completely new. Someone beautiful and entirely unrecognisable.
However, not everything is as perfect as the flawless stranger staring back at her in the mirror.
Because as Natalie comes to terms with her new body, it doesn’t take long for her to discover someone else. A girl with clear signs of mistreatment and neglect, her skin flushed with bruises that peek out from under her ragged clothes.
Looking at her, Natalie quickly realises she is no longer in the world she once knew. A place of modern luxuries and ordinary people. In fact, it’s far worse than she could have possibly imagined. Because she’s now trapped inside the last werewolf novel that she read.
But she’s not Aurora, the goddess-chosen white wolf girl of prophecy with magical powers. The one who will escape her painful enslavement, find her Alpha King second-chance mate, and overcome obstacles to prove their love for each other.
No... she has woken up in the body of Scarlett.
The villainess who will get in her way.... and one who won’t live to see the end of the book.
When Gwyneth opened her eyes, she found herself in a webnovel she had just binge-read, and she wasn’t just a random character—she was the villain’s mother! In the story, after the tragic death of her first husband, the original owner of her body had swiftly moved on and snagged a perfect new partner, only to heartlessly cast aside her son from the first marriage, worrying he would become a burden.
Now armed with knowledge of the impending plot twists and the looming shadows of her future villain son, Gwyneth glanced at her surprisingly alive first husband and groaned. With the script she had been dealt, she'd rather face a dragon than revamp this narrative! She was determined to rewrite her destiny, but how could she escape this villainous fate?
One night has changed everything in Sophia’s life. The night where she finds herself saving a villain in distress! A whirlpool of events has happened tangling their worlds even more that she found herself signing a deal with the devil.Raw romance, a whole messy kind of sexiness, and an undeniable attraction are suddenly served hot for her!Everyone should have been given the warning: the odds of dating of a villain is low—but never zero.
"I love you, I really really do~ please marry me" I closed my eyes in fear as I kneeled in front of the devil itself who had his hands warped around the female lead.
The next thing I knew I stood in the wedding hall wearing the white suit while in front of the Villain itself putting the ring on my finger.
"Now I declare you as husband and hu-husband? you may kill your husband"
It was supposed to be a straight Otome game where I was supposed to be dead while saving the FL. But here and I married to the villain itself.
"WHEN DID IT TURN INTO BL?"
I don't own the cover as I just did the editing of the art and credit goes to its owner
(book 1) Taika was a little different from other transmigration, she didn't wanted vengeance neither or wealth, she wasn't betrayed by her close ones neither did she get killed by anyone.
In fact Taika had a normal peaceful life, a lovely parents and doting siblings and great friends who supported her when she was facing hardship or trouble. Like a bad dream her prefect life shattered one very night, her life took a double turn when she woke up only to find out she is dead and was bond to a transmigration cycle without her consent.
She became a life puppet to the system cycle, due to her pure character she had to take twisted classes in order to be a villainess.
And it was killing her...no matter how hard she struggled... she could never escape this suffering or tortured it was a cycle which she had to pass through and eventually became them.
If you're itching to share your 'My Hero Academia' OC backstories with fellow fans, there are tons of awesome spots online where your creativity can thrive. One of my personal favorites is Archive of Our Own (AO3)—it's a fantastic platform for fanfiction and original character stories. The tagging system makes it easy for people to find your work, and the community is super supportive. Tumblr is another great option, especially if you want to pair your backstories with visual art or mood boards. The 'My Hero Academia' fandom there is incredibly active, and reblogs can help your OC gain traction.
Reddit’s r/BokuNoHeroAcademia is a solid choice if you’re looking for direct feedback and discussions. The weekly OC threads are perfect for sharing backstories and getting constructive criticism. For a more structured approach, forums like FanFiction.net or Wattpad offer dedicated spaces for OC-centric stories, complete with reviews and follows. Discord servers focused on 'My Hero Academia' are also goldmines—many have channels specifically for OCs, where you can roleplay, share lore, and even collaborate with others. I’ve stumbled upon some seriously imaginative OCs in these servers, and the instant interaction makes it feel like a live workshop.
Don’t overlook niche platforms like DeviantArt or Amino apps, either. While they’re more art-centric, plenty of users dive deep into OC backstories, especially if you’re blending text with character designs. Twitter (or X) can be hit or miss, but using hashtags like #MHAOC or #BNHAOC connects you with like-minded creators. Sometimes, all it takes is one viral thread to get your OC noticed. Whatever platform you pick, the key is engagement—reply to comments, join challenges, and don’t be shy about promoting your work. After all, the 'My Hero Academia' fandom thrives on passion, and your OC deserves to be part of that chaos!
