March is Women’s History Month, and Rosemary is exactly the kind of career you’re supposed to spotlight in a month like this—because her legacy isn’t just titles. It’s identity. It’s world-building. It’s sticking to a character so completely that the division starts feeling shaped around your presence.
Rosemary didn’t just become a fixture in TNA’s Knockouts Division. She became one of its defining textures—the darkness at the edge of the frame that made everything else feel more alive. You can build a division on great matches. TNA also built one on mythology, and Rosemary has been the walking, talking proof of that for ten straight years.
Before TNA: Courtney Rush, indie miles, and the credibility underneath the face paint
Before she was the Demon Assassin, Holly Letkeman built her name as Courtney Rush (and earlier as PJ Tyler), grinding through the Canadian and U.S. indies and working the women’s circuit when it still wasn’t getting consistent mainstream love. She wrestled in places where you either learn fast or you get left behind—especially SHIMMER and WSU, which were basically finishing schools for modern women’s wrestling in that era.
And that matters, because it’s why the Rosemary gimmick worked. It wasn’t smoke and mirrors covering up weaknesses. It was a fully formed character sitting on top of a wrestler who could actually work.
Notable pre-TNA promotions: SHIMMER, WSU, ACW, and a long list of indies across Canada and the U.S.
Notable pre-TNA championship: SHIMMER Tag Team Champion (with Sara Del Rey).
The arrival: Decay, the macabre cheerleader, and a debut that didn’t feel like a “new Knockout”
Rosemary’s TNA debut on January 26, 2016 is still one of the strongest character introductions the company has done. She didn’t walk in like a free agent signing. She walked in like a curse.
That debut immediately tied her to Decay—Abyss and Crazzy Steve doing the damage, Rosemary as the mind behind it. Decay wasn’t just a group. It was a vibe that helped define that entire era of Impact: chaotic, violent, weird in the best way, and consistent enough to feel like a brand identity.
And right away, you could tell she wasn’t there to be “another woman on the roster.” She was there to be an ecosystem.
The first major statement: a cage match, a crown, and a champion who felt supernatural
Rosemary winning the Knockouts Championship wasn’t some feel-good surprise. It felt inevitable—because the company had already framed her like a centerpiece.
On December 1, 2016, she beat Jade inside Six Sides of Steel to win the title, and that match is still important because it showed what TNA trusted her with: a gimmick-heavy environment where you still have to wrestle a coherent, physical match. Rosemary made the win feel like the belt belonged to the Hive.
Her reign (266 days) wasn’t remembered because it was “fine.” It’s remembered because it made the division feel dangerous. The title wasn’t just a trophy. It was a relic.
DemonXBunny: the storyline that made the Knockouts Division a genre, not just a division
If you want the Rosemary story that defines her importance to TNA, it’s Rosemary and Allie. DemonXBunny shouldn’t have worked on paper. It’s too weird. Too emotional. Too committed. Which is exactly why it worked—because they committed.
Rosemary wasn’t just protecting Allie. She was indoctrinating her. Guiding her. Claiming her. And Allie sold the fear and loyalty so well that the story stopped being “spooky wrestling” and became something rarer: women’s storytelling with lore.
That arc bled into the Undead Realm mythology and set the tone for years of Knockouts storytelling that wasn’t just “I want your belt.” It was identity, trauma, obsession, and the price of belonging to something bigger than yourself.
And the reason that story still matters today is simple: TNA is still mining it. The current callbacks—and the way the company is treating that history like canon—tell you how valuable Rosemary’s world-building really was.
The wars: Su Yung, the Undead Realm, and violence with imagination
Rosemary’s best TNA years aren’t just one title reign. They’re a web:
- The horror-rooted rivalry with Su Yung (and the Susie/Susan layers that came with it), where the supernatural angle still came with real physicality.
- The Decay reunions and evolutions, where Rosemary worked as the connective tissue between eras of the company.
- The cinematic Undead Realm chapters, where TNA let women carry a setting, not just a storyline.
That’s a big deal for Women’s History Month, because women’s wrestling history is full of performers who could’ve been bigger if they’d been allowed to lead long-term concepts the way men were. Rosemary got that opportunity—and she delivered.
The other part of her legacy: the tag-team record that quietly defines modern Knockouts history
Rosemary isn’t only a singles character. She’s also one of the most important tag team anchors in Knockouts history.
She’s a record four-time Knockouts World Tag Team Champion, and the variety of those reigns matters because it shows how adaptable she is:
- Decay (Rosemary & Havok) winning the titles in 2021 and again in 2024.
- A 2022 reign with Taya Valkyrie that proved she could pivot from supernatural ally stories into pure competitive pairing.
- The Death Dollz era (Rosemary, Taya, Jessicka) using the Freebird approach, which again shows Rosemary’s strength: taking a team concept and making it feel like its own little universe.
Rosemary doesn’t just “have partners.” She builds factions and families. The Hive always needs hivelings.
Ten years deep: longest-tenured Knockout, still essential, still weird in the best way
Here’s the part that deserves the loudest flowers: as of January 26, 2026, Rosemary hit ten consecutive years on TNA’s active roster and is widely recognized as the longest-tenured Knockout in company history. In a promotion that has survived rebrands, roster waves, creative resets, and entire era shifts, Rosemary has remained constant.
Not as a background player. As a tone-setter.
She’s also one of the longest-tenured talents still active in the company overall—and the key point is that she hasn’t lasted by standing still. She’s lasted by evolving the mythology without ever breaking the character’s spine.
The Women’s History Month takeaway
Rosemary’s career is a reminder that women’s wrestling history isn’t one style and it isn’t one approved template.
She’s a horror lead who can wrestle. A faction cornerstone who can headline. A tag-team record holder who can still carry singles lore. And a decade-long constant who helped make TNA’s Knockouts Division feel like it had its own language.
In a month meant to honor women who shaped the business, Rosemary gets her flowers for something specific:
She didn’t just live in TNA—she helped build the world the Knockouts wrestle in.

I’m the quiet one until the bell rings then I’ve got takes. I live for WWE NXT and TNA, I want every promotion to succeed, and I will absolutely roast the bad decisions on sight (because someone has to). Anime taught me to respect long-term storytelling; wrestling taught me that sometimes the plan is “we panicked” and called it “unpredictable.” The Miz got me into all of this, so yeah I appreciate confidence, commitment, and the art of talking like you’re already the main event. Now I bring that same energy to the page as the main writer for Late Night Crew Wrestling because if you’re not here to be must-see and tell the truth, why are you here?!
