In a blistering takedown that’s got the sports world reeling, Harry Potter queen J.K. Rowling has unleashed hell on transgender teen athlete A.B. Hernandez – the 16-year-old phenom accused of bulldozing through girls’ track events like a wrecking ball in lipstick.

The British billionaire author, no stranger to gender wars, dropped a bombshell thread on X yesterday, November 24, 2025, laying bare what she calls a “grotesque fraud” in youth athletics.

Rowling didn’t mince words, blasting Hernandez for allegedly faking hormone test results submitted to FINA, the global swimming body now cracking down on transgender competitors in women’s categories.

“Some people think it’s okay to see girls battered, medals swiped, and dreams crushed under the boot of male entitlement,” Rowling fumed in her opening salvo, her words slicing like a wand spell gone rogue.

“But I don’t. A.B. Hernandez isn’t just cheating the rules – he’s cheating an entire generation of girls out of fairness.”

The saga exploded back into headlines after FINA announced a lifetime ban on Hernandez from pro-level women’s events, citing “deliberate manipulation of eligibility data.”

Sources close to the investigation whisper that the teen’s submitted testosterone levels – clocked at a suspiciously low 2.1 nmol/L – were cooked up in a lab of lies.

Enter Rowling: the 60-year-old firebrand, who’s built a fortress defending women’s sports from what she dubs “trans ideology’s Trojan horse,” released her own independent bloodwork results yesterday.

Clocking in at a natural 1.8 nmol/L – well within female norms – the author’s labs stand in stark, humiliating contrast to Hernandez’s “evidence.”

“It’s not sorcery; it’s science,” Rowling tweeted, attaching scanned reports from a top London clinic.

“Compare these numbers side-by-side with the garbage A.B. fed FINA. One’s real. The other’s a fairy tale for fools who think biology bends to pronouns.”

The comparison? Rowling’s pristine printouts versus Hernandez’s docs, flagged by FINA auditors as bearing forged timestamps and mismatched lab signatures.

Insiders tell Daily Mail the discrepancies were “glaring” – like a house elf trying to pass as a house cat.

Hernandez, a California high school standout who dominated the 2024 Junior Olympics, snagged two golds in the triple jump and long jump, plus a silver in the 100m hurdles – all in the girls’ division.

But whispers turned to roars when rivals, including a tearful 15-year-old from Texas, came forward alleging the teen’s “unfair edge” left them bruised and broken.

“I trained my whole life for that gold,” the anonymous girl sobbed to Fox News affiliates last month.

“He leaped like a guy on steroids. We all saw it – the power, the speed. It’s not hate; it’s reality.”

Rowling, who’s poured millions into women’s rights causes, pounced on the scandal like a hippogriff on fresh meat.

“This isn’t about one kid’s confusion,” she argued in a follow-up post racking up 2.3 million views overnight.

“It’s about a system that lets boys in dresses dismantle Title IX brick by brick. FINA’s ban is a victory, but too damn late for the girls Hernandez humiliated.”

The author’s crusade echoes her past clashes – remember her epic feud with Olympic boxer Imane Khelif?

That 2024 Paris dust-up saw Rowling slapped with a French cyber-harassment suit for calling out the Algerian’s “male” punches.

She won that round too, with courts tossing the case amid leaked medical docs proving her point.

Now, with Hernandez in the crosshairs, Rowling’s doubling down, urging U.S. schools to “purge the pretense” before more young athletes shatter.

“Parents, coaches, wake up!” she implored.

“Your daughters aren’t props in a gender-bending play. Demand sex-based categories, or watch fairness drown in rainbow flags.”

The backlash? Swift and savage from trans activists branding Rowling a “TERF tyrant” – that tired slur for “trans-exclusionary radical feminist.”

One X troll sneered: “Jo’s just salty she can’t transfigure her bigotry into bestsellers anymore.”

But Rowling fired back: “Call me what you want. Facts don’t care about feelings – or fake lab slips.”

Hernandez’s camp, holed up in a Silicon Valley suburb, issued a mealy-mouthed statement via a family lawyer: “A.B. is a brave young woman navigating complex issues. We’re reviewing options and trust the process.”

Brave? Critics howl it’s code for “busted.”

FINA’s probe, launched in September after anonymous tips from track insiders, uncovered emails suggesting Hernandez’s team shopped for “sympathetic” labs willing to fudge results.

One whistleblower, a former coach, spilled to NY Post: “They knew the rules. Testosterone caps for trans women are ironclad at 5 nmol/L for 24 months pre-comp.

But A.B.’s numbers? Photoshopped perfection. It’s fraud, plain and simple.”

The fallout’s rippling nationwide.

In Texas, a school district yanked trans policies overnight, citing the Hernandez “hoax” as exhibit A.

California lawmakers, usually blue as the Pacific, floated bills mandating chromosomal checks for all state-funded sports.

Even President Trump’s inner circle – fresh off his 2024 reelection – nodded approval, with a Mar-a-Lago source quipping: “Donald’s always said: protect our girls. Rowling’s got the receipts.”

For Rowling, it’s personal.

The single mom who clawed from welfare to wizard wealth has long railed against “erasing women” – from prisons to bathrooms to podiums.

Her 2020 essay on the topic? A million-word manifesto that’s aged like fine firewhisky.

Now, at 60, she’s unbowed, her X feed a war zone of memes mocking “testosterone tourists.”

One viral edit: Hernandez mid-jump, captioned “When biology says no, but delusion says yeet.”

But amid the snark, Rowling struck a poignant chord.

“To every girl who lost to this charade: your pain isn’t invisible,” she wrote.

“You’re warriors. And warriors win in the end.”

As FINA’s ban locks in – no appeals till 2030 – Hernandez faces a wilderness of what’s next.

College scouts? Ghosted.

Sponsors? Circling the drain.

And Rowling? She’s already eyeing the next front: swimming pools, where trans teens are churning lanes like sharks in skirts.

“FINA fixed one pool,” she teased in her final tweet.

“Who’s draining the ocean?”

The clock ticks on a reckoning.

In the end, Rowling’s not just waving a wand – she’s wielding a truth serum.

And in the court of public fury, it’s Hernandez who’s turning green.
