Imagine Lord Voldemort, but born a woman. The same ruthless ambition, the same terrifying intellect, the same serpentine charisma—only now wrapped in beauty that could stop hearts and a voice that could make kings kneel.
That single “what if” has birthed one of the most intoxicating corners of Harry Potter fanfiction: female Voldemort fanfiction (also known as Fem!Voldemort, Lady Voldemort, Female Tom Riddle, or Dark Lady fics). And in 2025, this niche is absolutely dominates BookTok, Discord servers, and late-night AO3 binges.
Hi, I’m [Your Name or Blog Persona] — I’ve been reading, reviewing, and curating dark Harry Potter fanfiction for over ten years. I’ve personally devoured more than 400 darkfics, moderated two of the largest Tomione/Fem!Voldemort Discord communities, and have had my recommendation threads hit the front page of r/HPfanfiction multiple times.
This is the definitive, updated-for-2025 list you’ve been searching for: ten completed or actively updating female Voldemort masterpieces that deliver unforgettable characterisation, political intrigue, slow-burn tension, and pure Dark Lady energy. No abandoned fics. No low-effort gender-swaps. Only the stories that will ruin you in the best way possible.
Let’s begin.
Why Female Voldemort Fanfiction Is Exploding in 2025
The “Female Voldemort” tag on Archive of Our Own has grown 340% since 2020. On TikTok, #DarkLadyVoldemort and #FemVoldemort have collectively surpassed 180 million views. Why now?
- The rise of dark romance and morally gray heroines (think Fourth Wing, Manacled, and Haunting Adeline readers migrating to HP).
- A hunger for powerful, unapologetic female villains who aren’t redeemed by love—they weaponise it.
- Gender-bending Tom Riddle allows writers to explore ambition, beauty standards, misogyny in the wizarding world, and raw power dynamics in ways canon never could.
- 2024–2025 delivered several long-awaited completions and new breakout hits, reigniting the entire subgenre.
The result? Some of the smartest, sexiest, and most terrifying Harry Potter fanfiction ever written.

Now, the moment you scrolled for…
The Top 10 Best Female Voldemort Fanfictions of 2025
10. The Dark Lady Rises by Cleotheo
AO3 | 178,000 words | Complete | Mature
Classic for a reason. Cleotheo’s Dark Lady is cunning, elegant, and deliciously cruel. This is the fic that introduced an entire generation to the trope of Voldemort returning in a female body after the graveyard in Goblet of Fire. Political maneuvering in the Ministry, slow corruption of Harry, and a chilling romance with a pure-blood lord. If you want “Dark Lady wins” energy with zero redemption arc, start here.
9. A Queen in Shadows by Nircele
AO3 | 215,000 words | Complete (2024) | Explicit
Tom Riddle is reborn as a girl in 1940s Wool’s Orphanage and decides the wizarding world will kneel—or burn. This fic excels at showing how misogyny shapes her into something even worse than canon Voldemort. The romance with Abraxas Malfoy is toxic, magnetic, and perfectly paced. The final battle scene still gives me chills.
8. Blood and Gold by ObsidianPen
AO3 | 152,000 words | Complete | Explicit
Technically a Harry/Voldemort fic, but Voldemort spends most of the story in an exquisitely crafted female horcrux-body. ObsidianPen’s prose is lyrical poetry soaked in blood. The psychological horror, the soul-bond mechanics, the way female Voldemort weaponises desire—this is required reading for anyone who thinks dark romance peaked with Manacled.
7. These Deadly Vows by Morbidmuch
AO3 | 98,000 words | Complete (Jan 2025) | Explicit
A marriage-law Tomione where Tom Marvolo Riddle is Lady Thomasina Riddle, Slytherin’s heir and the most dangerous new transfer from Beauxbatons. The slow realisation that your arranged spouse is secretly building a dark army? Chef’s kiss. The courtroom scene in chapter 19 lives rent-free in my head.
6. Empress Ascendant by Elfwynn
AO3 | 290,000 words | Last updated Nov 2025 | Mature
The current reigning epic. Thomasina Slytherin (openly female descendant of Salazar) rises to power in the 1970s, seduces half the Sacred 28, and turns the First Wizarding War into her personal coronation. The political detail is insane—think Game of Thrones in robes. Still updating, but the author posts like clockwork.
5. The Art of Shadow and Bone by towardsmorning
AO3 | 112,000 words | Complete | Mature
Quietly one of the most beautifully written fics in the niche. Female Tom Riddle studies necromancy in Albania in the 1940s and returns as something not entirely human. Minimal romance, maximum existential dread. If you love atmospheric horror with your Dark Lady, this is perfection.
4. Timeless by alexandra_emerson
AO3 | 420,000 words | Complete | Explicit
The undisputed Tomione masterpiece, reimagined with female Tom Riddle. Time-travel, enemies-to-lovers spanning decades, and a romance so intense it hurts. The way alexandra_emerson writes Thomasina’s descent into madness while still making her sympathetic is god-tier characterisation. If you only read one fic on this list, make it this one.
3. Of Dark Lords and Crows by TheFictionist
AO3 | 185,000 words | Complete (Sept 2025) | Explicit
Harry Potter dies in the forest and wakes up in 1943—only Tom Riddle is now a girl who has already killed Myrddin Slytherin and taken his place. The slow-burn between Harry and this new Dark Lady is electric. The twist in chapter 32 broke the entire Discord server when it dropped.
2. Honor and Obscurity by MourningStar
AO3 | 335,000 words | Complete | Mature
For years the gold standard of female Voldemort characterisation. Lady Voldemort returns in 1995 more powerful and more beautiful than ever, and Harry Potter becomes her unwilling general. The psychological chess game between them is breathtaking. The ending is controversial, but I still think about it weekly.
1. Nocturne by TheCarnivorousMuffin & Vinelle
AO3 | 260,000 words | Complete | Explicit
The crown jewel of 2025. Female Tom Riddle attends Hogwarts with Alphard Black and Orion Black as her devoted knights. This fic rewrites the entire timeline with surgical precision while somehow making Lady Voldemort the most compelling protagonist in fanfiction. The prose is flawless, the romance is devastating, and the final chapter will leave you staring at a wall for an hour. If there is one female Voldemort fanfiction you read before you die, let it be Nocturne.
Bonus Mentions & Hidden Gems You Don’t Want to Sleep On
These didn’t quite crack the top 10 (usually because they’re newer, shorter, or still updating), but they’re outstanding and deserve your bookmarks:
- Serpentine by darklordzilla (AO3, 82k, updating monthly) – A female Tom Riddle who never splits her soul and instead becomes the shadowy power behind the Ministry in the 1960s. Spy-thriller vibes with a razor-sharp protagonist.
- Aurea by TheMourningMadam (AO3, 145k, complete 2025) – Golden-Age pure-blood society decadence with Lady Voldemort as its glittering, poisonous queen. Think The Great Gatsby but everyone is a blood-purist and someone dies every chapter.
- The Heiress of Slytherin by LadyHallows (Wattpad, 220k, complete) – The rare Wattpad gem that actually has better grammar than half of AO3. Epic scope, dragon-riding battles, and a female Voldemort who collects horcruxes like jewellery.
- Obsidian Crown by halfpromise (AO3, 65k one-shot collection) – If you just want the absolute best snippets of Dark Lady energy without committing to a novel, this collection is pure serotonin.
- Lady of the Lake by seollem (AO3, 98k, updating) – Avalon mythology woven into the Voldemort origin story. Hauntingly beautiful prose and the most unique magic system I’ve seen in years.
Common Tropes in the Best Female Voldemort Fics (And Why They Work So Well)
The top-tier stories all play with a core set of ingredients. Here’s what the masters do differently:
- Beauty as a Weapon, Not a Redemption Unlike canon Voldemort, the Dark Lady is almost always described as stunning—and she knows it. She uses desire the way canon Voldemort uses fear.
- Tomione Done Right The enemies-to-lovers tension is slower and more intellectual. It’s less “I hate you” and more “I understand you better than anyone ever will, and that terrifies us both.”
- Pure-Blood Politics on Steroids Sacred 28 marriages, Wizengamot schemes, and ancient blood rituals become central plot engines instead of background flavour.
- Blood Magic & Necromancy Porn The best authors invent entire branches of dark magic that feel like they could have existed in canon but were too horrifying for a children’s series.
- “She Wins” Endings (or Pyrrhic Victories) Readers in this niche overwhelmingly prefer stories where the Dark Lady either conquers Britain or goes down in a blaze of legendary glory—no sudden heel-turn redemption in the last three paragraphs.

Frequently Asked Questions About Female Voldemort Fanfiction
Q: What is the most popular female Voldemort fanfiction of all time? A: By raw kudos, it’s still Honor and Obscurity by MourningStar (2018–2022) with 28k+ kudos, but Nocturne is on track to surpass it before 2026.
Q: Are there any completed “Female Tom Riddle raises Harry” stories? A: Yes! The best is The Serpent’s Gaze by Freya Ishtar (complete, 180k) — dark mentorship with surprisingly tender moments.
Q: Is there a Manacled-level dark female Voldemort fic? A: Nocturne and Blood and Gold are the closest in terms of emotional devastation and explicit darkness.
Q: What’s the difference between Fem!Voldemort and Dark Lady Harry stories? A: Fem!Voldemort is genderbent Tom Riddle/Lord Voldemort. Dark Lady Harry is Harry Potter herself going dark (sometimes with Voldemort’s traits). They’re related but distinct niches.
Q: Where can I read these if AO3 is down? A: Most authors also upload to FanFiction.net under the same pen name, and many have begun mirroring to their own sites or to ficbox.co after the 2024 AO3 outages.
Female Voldemort fanfiction isn’t just gender-swapped villainy. It’s the fantasy of a woman who is allowed to be brilliant, ruthless, sensual, and unredeemable—and still be the protagonist of her own story. In a world that still flinches when women want power, these fics let us watch a witch-queen conquer without apology.
If even one story on this list keeps you up until 4 a.m. with your heart racing, then I’ve done my job.
