Which Platforms Host Original Harley Quinn Fanfic Storylines?

I ran into that niche searching a while back because I wanted more grounded, street-level Gotham stories than the bombastic comic arcs sometimes offer. Obviously Archive of Our Own is the powerhouse—their Harley Quinn/Ivy tag is massive, and you can filter by 'Alternate Universe - Canon Divergence' or 'Alternate Universe - Modern Setting' to find what feels like original storylines set in those characters' essence. Some writers basically use Harley's voice and chaos to tell completely new heist or redemption plots that could stand alone.

Less obvious but fruitful is Tumblr. Certain blogs write serialized prose in the tags, building out multi-chapter Gotham City Sirens narratives that have little to do with any published comic. They’re often moodier, more character-study focused.

I’ve also seen original Harley-centric arcs on FanFiction.net under the 'Batman' section, filed as 'OC' or 'Original Story' even though they feature her. They tend to be longer, novel-length works, sometimes crossovers with entirely different genres. The search there is clunkier, but sorting by favorites can surface gems that reinvent her world entirely.

AO3 is your best starting point. Use filters like 'Alternate Universe' and exclude crossovers if you want pure original plots. I’ve found complete sagas there where Harley is a radio host in a 1940s noir city or a magical girl fighting original monsters. The tags are detailed enough to spot truly inventive settings.

Some independent blogs and forums also host serialized original arcs, but they’re harder to track down without direct links from fandom communities. Discord servers dedicated to Harley or DC fanfiction sometimes have channels for original stories, shared as Google Docs or PDFs.

Honestly, I think the distinction gets blurry. Any platform with a strong DC Comics or Batman category will have Harley Quinn stories that diverge into original territory. I've read stuff on Quotev that felt like entirely new novels just using her likeness and mannerisms. The plot was about a carnival troupe solving mysteries, nothing to do with Gotham.

Webnovel sites like Scribble Hub sometimes host them under 'Fanfiction' too, often with darker or more mature original arcs. The tagging isn't as robust as AO3, so you have to dig. A lot of these writers treat Harley as a flexible archetype—the chaotic, resilient anti-heroine—and drop her into wholly invented conflicts.

My main tip is to search for 'Alternate Universe' plus 'Harley Quinn' on AO3, then skim summaries for mentions of original villains, settings, or occupations. That usually signals a storyline built from scratch around her core personality.

Most fanfic platforms host them, but the vibe changes per site. AO3’s tagging lets authors flag 'Alternate Universe - No Powers' or 'Original Characters' alongside Harley, which is where you find the truly original plots. I follow a writer who built a whole series around Harley running a chaotic therapy practice in a mundane city—no Joker, no Batman, just her personality driving the story.

Wattpad can surprise you too, with more genre-blending; I stumbled on a Harley Quinn space pirate saga there once. The algorithms push similar original character-focused stories if you engage with a few.

Forum-based places like SpaceBattles or Sufficient Velocity occasionally have quests or collaborative stories starring Harley in completely original scenarios, like a corporate espionage thriller or a historical fantasy setting. Those feel like communal storytelling experiments more than traditional fanfic.
