They say it all the time in the world of professional wrestling and otherwise – anything is possible, never say never. Talking about the WWE in particular, it's not uncommon for "impossible" returns or debuts to take place, and you can bet Michael Cole will be yelling "oh, my!" in astonishment as fans erupt in glee at seeing an old favorite return, or a hot free agent make their much-awaited WWE debut. That's true with male, as well as female wrestlers, but there are also times when the WWE's got a wrestler or two on their you-know-what list, essentially guaranteeing that you won't ever see them again, or see for the first time on the company's programming.

When making this list, we qualified "former" WWE women as being those who competed on the company's main roster or down in developmental. As for those who are current women who have yet to join WWE, these include wrestlers or on-air personalities who have never signed WWE contracts and/or appeared on main roster or NXT programming, though we did make exceptions for those who had unsuccessful WWE tryouts, and Mae Young Classic competitors who weren't signed to WWE contracts. We hope we aren't spoiling things for any of you, so here it is – 15 former WWE women whom the company won't welcome back to its ranks, and 6 current, non-WWE women whom they most likely won't ever be signing.

21 Current: Jessicka Havok

Yes, she did try out for the WWE a few years back, but we're filing her as "current" based on the criteria we mentioned in the intro.

A former TNA Knockouts Champion who secured a chance at a WWE tryout in 2015, Havok found herself in hot water when social media users dug up some tweets from the tall and powerfully built wrestler’s past, which included examples of racist and homophobic content.

Once the offending tweets were uncovered, Havok frantically tried to delete most of them, then tried passing blame to an ex-boyfriend.

She ultimately issued an apology, saying that she was young, new to social media, and “very immature” at the time of the tweets. Many felt that this was weak (Havok was, for one, an adult at the time the tweets were posted), and believe that was the reason she flunked her WWE tryout.

With WWE still having a hard time bringing back Hulk Hogan three years after his own racially-charged leak, it will be a major shocker if Havok is somehow given a second chance by the WWE.

20 Former: Gail Kim

The WWE simply didn't know what to do with Gail Kim. This didn't just happen once, but in two WWE runs, and it was truly a waste of talent after winning the WWE Women's Championship in her first night on the main roster. Apparently, Vince McMahon didn't think that a woman of Asian descent would become over with WWE fans, but even after he was swayed to hire the talented female grappler, she just wasn't given the sustained push she deserved.

All this had weighed on Kim, who was treated much better during her stints in TNA/Impact Wrestling, and had even become the first woman to be inducted into the company's Hall of Fame.

It's still hard to forget how she decided to flip the proverbial bird to WWE toward the end of her second run – by deliberately eliminating herself in a battle royal.

It was almost as if she was telling WWE, "screw this, I'm going back to a place where talented women are actually valued by the company." Indeed she did, but even with WWE's Women's Revolution/Evolution going full speed ahead, WWE remains uninterested in inviting Kim back to the company, even for onetime appearances on Raw 25 or the women's Royal Rumble. The feeling is mutual, as Kim is still more than happy to shoot about her negative experiences as a WWE Diva.

19 Former: Ashley Massaro

There's a dime a dozen Diva Search products whom we could include in this list under the "former" category, but we promised you "only" 15, so we're limiting things to some of the more memorable, including 2005 Diva Search winner Ashley Massaro. As we explained in another list, Massaro's gimmick had a lot of punk (or should we say, pop-punk) influence to it, and that's arguably the most memorable thing about her. Other than that, she wrestled in many a cringeworthy match (including those oh-so-popular bra-and-panties matches), was notoriously injury-prone, and was the subject of a Rolling Stone expose that alleged she was working as an escort.

There's really no sweet way to put it – Ashley was not a good wrestler.

At 38, she's long in the tooth by women's wrestling standards, and she's exactly the kind of female wrestler WWE wants to steer clear of. You've also got to consider the things she accused WWE of; in 2016, she was part of the massive concussion lawsuit against the company, but she also alleged that WWE covered up an assault that supposedly took place during a tour of Kuwait. WWE usually isn't keen on hiring wrestlers who sued them, and you shouldn't consider Massaro as one of those exceptions to the rule.

18 Former: Summer Rae

Having been signed by the WWE in 2011 after three years as a Lingerie Football League player, Summer Rae (now using her real name, Danielle Moinet, in the indies) first became known to main roster fans as Fandango's valet and dance partner. It was, to be fair, a role that suited her well, but she had her fair share of gimmicks prior to her late 2017 release – Layla's rival turned ally, Rusev's new girlfriend in the "love quadrangle," woman who betrayed Damien Mizdow as he lost his feud against The Miz. Yup, it's the dancing we mostly remember.

While Summer Rae never caused trouble behind the scenes for WWE, there are two things that make her chances of returning to the company slim to none.

One, she's turning 35-years-old later this year, making her a bit older than the average female wrestler. Two, she's a remnant from the Divas Era who didn't cut her teeth in the indies like most of today's top women – sure, she's not as bad as some of the worst Diva Search products, but she still wasn't that good either. It's good that she's resuming her wrestling career in the independent scene, but as far as a WWE return goes, the sun has probably set on Summer Rae.

17 Current: Rosemary

Rosemary is one of the most skilled and unique female talents who has yet to work for the WWE in any capacity, and make no mistake, it would be great to see her on the roster one of these days. However, that appears to be little more than just wishful thinking at this point in time.

Inasmuch as we'd still like to see Rosemary make her way to WWE, possibly via the NXT route like many an ex-Impact Wrestling colleague, we're afraid the ship might have sailed on that possibility, or is about to. We're not sure when her contract is due to come up, but when it does expire, that'll likely take place after her 35th birthday in November.

With rare exceptions such as the returning Mickie James during that one NXT match against Asuka, and last year's top newcomer, Shayna Baszler, few NXT women are in their mid-30s or older, which could hurt Rosemary's chances of getting a good push. Furthermore, NXT has big plans for SAnitY's Nikki Cross, who's six years younger and works a similarly dark gimmick, and was purposely left behind in developmental when her male stablemates got the call-up. That's reportedly a result of these big plans, which might include an NXT Women's Championship run in the near future.

16 Former: Cameron

She was the first casualty in what may have been Tough Enough's worst season ever, and as you should know, that was where she told "Stone Cold" Steve Austin that Melina vs. Alicia Fox was her favorite match of all-time. Somehow, Ariane Andrew got a full-time job with the WWE, and even made it to the main roster as Cameron, one-half of Brodus Clay's Funkadactyls.

Of course, it was after the Funkadactyls when Cameron committed one of the biggest botches in recent WWE history – pinning friend-turned-rival Naomi while she was lying on her stomach, then loudly demanding that the referee "count it." She was hardly used in the year or so leading to her 2016 release, and not even NXT could help make her relevant, or help her improve her skills. And we don't believe she's going to get a second chance with WWE, even if she's young enough to theoretically get one.

The "count it, ref!" blooper is one thing, but the main reason why WWE wouldn't be interested in Cameron all boils down to her lack of improvement in the ring, as well as poor social media etiquette; reports suggest that WWE decided to fire her after she supported Ryback in his "equal pay for everybody" Tumblr post. Moreover, she's another old Divas Era-style wrestler who may be out of place in the Women's Revolution – great looks, pedestrian in-ring ability.

15 Former: Aksana

The all-female third season of the NXT game show helped usher in two women who stood out right away for their potential to break the "Diva" mold the WWE favored at that time – Season 3 champion Kaitlyn and third-placer AJ Lee. Second-placer Naomi and fifth-placer Maxine (now Catrina in Lucha Underground) eventually proved to be more than competent in the ring. Then you have the fourth-placer, Aksana, who stuck out as someone who was closer to the traditional WWE Diva archetype than most of her fellow Season 3 rookies.

From her entrance theme to her ring attires, it was clear that Aksana was another one of those "fanservice" Divas, not as skilled in the ring as the other female rookies who came out of NXT Season 3, not any good with her promos, but definitely easy on the eyes. After storyline relationships with Teddy Long and (Antonio) Cesaro, it became clear that WWE creative had nothing for the Lithuanian fitness model, and she was included in WWE's wave of mass releases in 2014.

In all, Aksana's limited skill set makes it doubtful that WWE will ever let her be part of the Women's Revolution.

Yes, you can copy-paste that last sentence for many of the women in the "former" category, but more so with Aksana than with others, given how she's fallen off the radar since her release.

14 Former: Zahra Schreiber

Don't deny it – you probably were shocked to learn recently that Sonya Deville's girlfriend of the past two years is none other than Seth Rollins' controversial ex, Zahra Schreiber. We won't go as far as criticizing Deville for dating someone with such a checkered past, but her presence on the SmackDown Live roster most likely won't be enough to convince WWE to give Schreiber a second chance.

For the benefit of those who are unaware or might have forgotten, Schreiber was involved in two separate controversies while part of the NXT roster, first when private pictures of hers had leaked out on social media, and briefly onto the WWE website as well, courtesy of Rollins' apparently hacked Twitter account. This angered his then-fiancee, Leighla Schultz, who retaliated by posting photos of Rollins in the buff, and breaking up with her man for apparently seeing the previously unknown NXT talent on the side.

The second controversy ultimately led to Schreiber's firing, as it was revealed later on that the heavily inked wrestler had a thing for Nazi memorabilia, supposedly because she "loves history," and had made several racially offensive comments on social media years before joining NXT. That, we'd say, is more than enough reason for WWE not to touch her with a ten-foot pole.

13 Current: Dixie Carter

Last year, there were several rumors swirling about Dixie Carter, the woman who was once synonymous with Impact Wrestling back when it was still called TNA, joining the WWE, much like Eric Bischoff signed a deal with his onetime bitter enemy and helped usher in WWE's first brand split era. Specifically, these rumors hinted that Carter might be part of the "Kurt Angle's secret" storyline and reveal that she and the Olympic gold medalist had an affair back when he was one of her employees, but we all know that wasn't the case – Angle's "secret" came in the form of a "son" he had "fathered" out of wedlock when he was still in college, and that kayfabe son turned out to be none other than Jason Jordan.

Before we digress too much, let's explain why we don't think Dixie will follow in Uncle Eric's footsteps and become an on-air authority figure on WWE television like she was in Impact.

Yes, even with her kayfabe nephew Ethan keeping his EC3 ring name on NXT, it's highly unlikely that Carter will be allowed to tear down wrestlers and, heavens forbid, be involved in romantic storylines with some of them. That's because WWE has, and will likely always have Stephanie McMahon playing such a role, thus making Dixie superfluous. Also, let's admit it – it's not like she has Bischoff-level talent as a villainous authority figure anyway.

12 Former: Kharma

Among the many women who have passed through WWE's ranks through the years, Kharma is one of the most disappointing, and it's through no fault of hers for the most part. Initially booked as a monster heel, the woman usually known in the ring as Awesome Kong went on an extended leave of absence after an in-ring breakdown and her admission that she was pregnant. She then returned for the 2012 Royal Rumble to scare the bejesus out of heel Michael Cole, but that turned out to be her only official WWE match. Sadly, WWE wasn't ready to book a physically intimidating woman in an era where traditional "Divas" still reigned supreme in women's wrestling.

There are several reasons why we believe WWE isn't keen on Kharma making a return to the company. One, her age – As she's turning 41 this year, she'll automatically become the oldest female talent on WWE's roster. Two, the fact that WWE has Nia Jax on board, and appears to be satisfied with her past progress as a monster heel. (The jury's still out on her babyface run, but let's not digress too much.) Three, she's carving out an acting career now that she's transitioning into part-time wrestler status, with wrestling fans eagerly awaiting her return as Tamme "Welfare Queen" Dawson on GLOW's second season on Netflix.

11 Former: Eva Marie

You knew you'd see Ms. All Red Everything on this side of the list. Eva Marie was the winner of WWE's last, untelevised Diva Search in 2013, and after just two weeks of basic training, she was promoted to the main roster, where she was placed in multi-woman tag matches to hide her obvious deficiencies, while also getting a lead role in WWE and E!'s brand new reality series, Total Divas.

The rest is history, as nothing WWE did seemed to help Marie improve in the ring.

Fans booed her mercilessly regardless of her heel or face alignment, and her numerous in-ring (and on-mic) botches were plentiful enough to fill multiple Botchamania compilations. Inexplicably, she was included in WWE's 2016 brand draft, and after (sort-of) debuting with a gimmick that was actually over, a Wellness Policy violation took Marie offscreen for good. After almost a year off television, she was released by the WWE in August 2017.

Much as WWE tried to make Eva Marie a star, we're confident WWE isn't itching to rehire her, even in a non-wrestling role. She's made it clear that her focus is now on acting and modeling, though we have to give her props for not shooting hard on the WWE post-release, and even defending pro wrestling after Mia Khalifa disrespected it on her YouTube talk show.

10 Former: Sable

She wasn't a wrestling fan when she was brought in to the WWE alongside her real-life husband at the time, Marc Mero, and she didn't grow up a wrestling fan either. Now that she's married to a man who loves the money aspect of pro wrestling than he loves the concept of it, we don't think Sable would be high on WWE's priority list, even if it's for a onetime appearance.

The current Mrs. Brock Lesnar has had a rocky relationship with the WWE for the most part. When she first left the company in 1999, she sued WWE for harassment and for fostering unsafe working conditions; one would have thought that would be the end of it. But she was back with the company in 2003, and while her second run lasted only a year, that was also where she would meet her Beast of a husband, who seems to have had one foot out of WWE's door for the longest time. When Brock finally leaves WWE, there'd be no chance in hell (sorry, Vince) Sable appears for the company, even during nostalgia-heavy specials.

Yes, we will agree that she looks fantastic for a 50-year-old, but at this point, she's perfectly happy to stay home on the Lesnar farm with her husband. (Who's oftentimes at home anyway, given how rarely he appears on TV or PPV.)

9 Current: Piper Niven (aka Viper)

Last year, Scottish wrestler Viper, or Piper Niven as she was known at that time, was among the 32 women who took part in the first-ever Mae Young Classic, but as is the case in these tournaments, she was one of the many also-rans who did not get WWE contracts. She did quite well for herself, making it to the third round where she was defeated by Toni Storm, but we don't think WWE would be too hot on giving the Vixen of Violence an actual contract with the company.

The reason behind this, quite sadly, has nothing to do with skill or lack thereof – she's obviously talented, not to mention quite athletic for a woman her size. But even with WWE's Women's Revolution in mind, where female wrestlers are hired based on their in-ring ability before anything else, as opposed to good looks and shapely bodies, we must remember that it's still Vince McMahon who's in charge of the company.

Vince may be okay with Nia Jax holding the Raw Women's Championship and getting quite a good push, but given his tendency to be out of touch when it comes to creative decisions, we don't think he'd be too keen on having too many plus-size women on his roster.

8 Former: Jazz

When talking about WWE's top female wrestlers of the Ruthless Aggression Era, Jazz's name is one that is often left out. She's mostly forgotten these days, despite notable feuds against the likes of Trish Stratus and Victoria, and her reputation as one of the few legitimately talented workers WWE had in its women's divisions of the time. She's still actively wrestling at the age of 44, and currently reigns as the NWA World Women's Champion, but we're highly doubtful on the chances that she'll get a one-off invite for a special event, say, forthcoming Women's Royal Rumble matches.

For one, Jazz is one of those who have had little good to say about WWE in shoot interviews, as she's especially salty about how she and her husband, Rodney Mack, were fired by the company in 2007, because they weren't the types to kiss anyone's behind. It's also notable how she possibly angled for a return to the company just about a month ago – a profane series of tweets directed at Charlotte Flair, where she suggested that Charlotte only got to where she is today because of who her father is. It's still unclear if she was shooting or working at that time, but calling out one of WWE's best-known females in such a way certainly won't endear Jazz to the powers that be in the WWE.

7 Former: Sunny

This one, to be very honest, is as close as you can get to a slam dunk entry in the "former" category. Where do we begin with Tammy Lynn Sytch, better known to WWE fans of all ages as Sunny? Originally booked in 1995 as the female half of The Bodydonnas and playing the role of an annoying fitness buff, Sunny's sex appeal was evident from day one, and she would soon shed this gimmick in favor of others that truly accentuated her status as WWE's "original Diva."

With Sunny catapulted to celebrity status, as well as the "honor" of being AOL's most downloaded woman, she was also becoming quite the headache behind the scenes, earning the ire of the Kliq (among others) and developing more than her share of bad habits, as she, per locker room rumors, openly cheated on her real-life boyfriend, Chris "Skip" Candido. The TL;DR version of Sunny's story is this – she was a train wreck even before she celebrated her 30th birthday, and she continues to struggle to get her act together, unlike most other contemporaries who have since sorted their troubled lives out.

Being that WWE had stopped spending money to sponsor Sunny's rehab – the first and only time the company has given up on a former talent in such a way – that's all the proof you need to believe that WWE won't even think of rehiring her ever again.

6 Former: Kaitlyn

The winner of the all-female season of NXT back when it was a reality show, Kaitlyn entered the WWE with lots of promise, and if you come to think of it, she might have been the most successful NXT winner from the "game show" era (though Wade Barrett might have some "bad news" and disagree with that). As a rather atypical women's wrestler in the tail-end of the "Divas" era, Kaitlyn held the Divas Championship for more than five months, until a rather unusual backstage incident allegedly led to the end of her title reign.

As rumor has it, Kaitlyn was being punished for something that sounds more than a little trivial – she supposedly interrupted Stephanie McMahon backstage while the Billion Dollar Princess was talking to someone else.

Several months after losing her title, Kaitlyn left the WWE, retiring from pro wrestling at the age of 27 to focus on marriage and business.

While Kaitlyn has since split from her bodybuilder husband, defeated some personal demons, and announced her return to wrestling, she doesn't look like someone WWE will want to rehire. Pettiness does run in the McMahon family, and it won't be surprising if Stephanie still feels so slighted by that little backstage interruption that she wouldn't let Kaitlyn, who's still young enough at 31 and in great physical shape, to be a part of what we now call the Women's Revolution/Evolution.

5 Current: Christina Von Eerie

Christina Von Eerie has, in an in-ring career that has lasted over a decade, quietly reached indie veteran status despite being only 28 as of this writing. Last year, she spent some time in the Impact Wrestling roster (technically), having been the long-running GFW Women's Champion at the time GFW and Impact merged, but she hasn't been doing much since then. Does she have a shot at competing in the WWE as yet another punk rock-inspired wrestler with more than her fair share of body ink?

Just like plus-sized female wrestlers, it would almost seem as if WWE has an unwritten quota for heavily tattooed female wrestlers – yes, that's even if you consider how Lita is a WWE Hall of Famer and is widely considered a trailblazer in the world of pro wrestling. Currently, WWE's most heavily tattooed female wrestler is Ruby Riott, whom the company hasn't quite made into a big main roster star just yet, but might be getting there. Vince McMahon, with his antiquated views, probably doesn't want too many tattooed punk rockers in his women's divisions, hence our skepticism that Von Eerie would one day get a chance to wrestle in the WWE.

4 Former: Melina

Although she definitely possessed the looks required of WWE's Divas during that best-left-forgotten "eye candy" era, Melina was a rarity, in the sense that she actually had substantial experience in the independent scene, and was quite skilled in the ring. She originally debuted alongside then-boyfriend Johnny Nitro and Joey Mercury, making up one-third of MNM, and from there on in, she became one of the most successful females WWE had in the first decade of the 2000s, picking up three Women's Championships and two Divas Championships.

Unfortunately, she also had quite the reputation backstage as a very difficult person to deal with.

Now in her late 30s and occasionally active in the indies, it can be argued that Melina can still bring something to the table if WWE should invite her back. But being that she wasn't among the many onetime returns in the first-ever women's Royal Rumble, it's safe to say WWE's door isn't open for someone who was the source of so much backstage drama back in the day. WWE's got enough of it on the female side with Lana, as well as the real-life Alexa Bliss vs. Sasha Banks beef, so why would they gamble on this former locker room heat magnet who is, for lack of a better term, a few years past her prime?

3 Former: Christy Hemme

As the first-ever televised winner of WWE's Diva Search competition in 2004, Christy Hemme was seemingly poised for stardom in the company's ranks, but she would soon leave to join the competition. While at TNA, she greatly improved in just about every facet of wrestling, and though she appears to have retired from wrestling to focus on motherhood and other endeavors, we probably won't see her in any way, shape, or form on WWE television or pay-per-view.

While she’s maintained that she left WWE on her own accord toward the end of 2005, there have been myriad rumors hinting at what might be the real reason why WWE wouldn’t want to welcome her back.

Allegedly, Triple H and Hemme got a little too close to each other for comfort, and being that the Game was already married to Stephanie McMahon at that time, Stephanie reportedly got suspicious about Hemme being “excited” to travel with Triple H and Batista. There’s also the suggestion Hemme made in a 2008 statement where she cited her “morals and values” as a reason why she left WWE.

The rumors may still swirl from time to time, but it appears Hemme is content to lie low from professional wrestling and support her former colleagues behind the scenes.

2 Former: Sofia Cortez (aka Ivelisse Velez)

Looking back at the fifth season of Tough Enough, this seemed like one of the years when the female competitors had more promise than the men. For what it's worth, Cameron did spend a few years in the WWE after Tough Enough, and Ivelisse Velez could have gone further had it not been for a leg injury she suffered during the reality-style competition.

That's right – you may have forgotten it already, but the Lucha Underground mainstay had once spent time in WWE under the name Sofia Cortez, competing in both the FCW and NXT versions of WWE's developmental ranks, and teaming with Paige and Raquel Diaz in the Anti-Divas stable. Unfortunately, she was gone from the company in August 2012, her abrupt release a mystery until it was revealed that she was one of the many wrestlers allegedly bullied and mistreated by then-NXT head trainer Bill DeMott. Meanwhile, Ivelisse was enjoying far more success away from WWE, wrestling in the indies mostly under her real name, and eventually becoming a key part of Lucha Underground programming.

Although we don't think WWE has much tolerance for DeMott's drill sergeant-like techniques as head trainer, the sad thing is that he might have a better chance of returning to the company than Ivelisse does. For some reason, WWE isn't too keen on rehiring whistleblowers, so while she's definitely young enough for a return, we're not exactly counting on it.
