Callisto – Dania Ramirez

Appearing in X-Men: The Last Stand, the blink-and-you-miss-her Callisto is feisty and sexy enough to dare go head-to-head with Halle Berry’s Storm. The fact that Storm beats her up and then electrocutes her to death is a mere technicality. Anyway, this leather-clad and tattooed mutant makes a fine addition to Magneto’s Brotherhood of Mutants. Until she dies, that is. At least Dania Ramirez lives on to tingle the man-cannon, though.

Catwoman – Michelle Pfeiffer

This feline femme fatale has been extant since the very earliest days of Batman’s crime fighting career, and it’s pretty easy to see why she’s been worth keeping around. With her skintight catsuit and seductive purr, Michelle Pfeiffer’s puissant pussycat makes even the Dark Knight a-throbbing. Not bad for a 70-year-old. Originally named Selina Kyle – a bedraggled and introvert secretary – Pfeiffer’s character is transformed into Catwoman after being thrown out of a lofty office window in 1992′s Batman Returns. She is then somehow revived by a host of feral cats and goes home to sew a costume together before exacting sexy revenge. Meow! It remains to be seen if Anne Hathaway’s upcoming portrayal of Selina Kyle in The Dark Knight Rises can challenge Pfeiffer’s sensual endeavor.

Mystique – Rebecca Romijn

From her first appearance in Ms. Marvel #16, the lithe, azure goddess that is Raven ‘Mystique’ Darkholme has enjoyed a special place in the pantheon of sizzlin’ supervillainy. Possessing fearsome skills in combat, acrobatic dexterity and the power to endlessly shape-shift, Mystique is certainly a mutant who can hold her own. Indeed, she is put to good use at different times to spy on, infiltrate and assassinate various people who stand in her and the behelmeted Magneto’s way. She sports what might also be the best costume ever devised (for a hot movie supervillain, anyway), and you can’t deny that Mystique pulls off the blue skin look far better than Papa Smurf ever did. According to ComicBookHotties.com: “To play Mystique, every day Rebecca had to start out nude, and then two female make-up artists would apply blue body paint, and other stick-on parts, for 8 hours a day.” No wonder X-Men was a blockbuster hit. If anybody wants me, I’ll be back at school learning to be a make-up artist.

The Fox – Angelina Jolie

Based in the world of Mark Millar’s comic book series, the 2008 movie, Wanted, centers around James McAvoy’s character and his unwitting awakening as an unlikely assassin. The Fox (played by the buxom Angelina Jolie) is instructed to recruit him into an organization of very naughty people called The Fraternity. Font of knowledge Wikipedia tantalizingly (and somewhat bafflingly for those who haven’t seen the movie) describes The Fox as: “An assassin who shoots everyone in a sandwich shop.” Well, I don’t know about you guys, but I’d be more than willing to overlook The Fox’s lunchicidal tendencies in exchange for a game of grab ass.

Dark Phoenix – Famke Janssen

Jean Grey’s naughtier and far more menacing alter ego is Dark Phoenix. Portrayed by the sleek Famke Janssen, Phoenix was always within Grey, locked away since her youth by the follically-challenged Professor X. It was only when Grey sacrificed herself for her comrades-in-black-rubber that her massively potent dark side came to the fore. Phoenix became a class 5 mutant – immensely powerful and awesomely dangerous – quite possibly the most formidable villain ever created. She was only stopped when Wolverine confronted her in X-Men: The Last Stand’s climactic finale and stabbed her in the guts. And what lovely, lovely guts they were. Dark Phoenix was ranked as IGN’s 9th Greatest Comic Book Villain of All Time (2009).

Lady Deathstrike – Kelly Hu

Like many others in this list, the movie version of Lady Deathstrike traveled a different path to her character in the comics. But we aren’t going to complain when the upside is that we get to look at the delicious Kelly Hu and her lovely, erm, acting talents. This version of Deathstrike is another one of meaty-faced William Stryker’s brainwashed mutants. She shares all the abilities that make Wolverine so goddamn killer: cat-like agility, bear-like strength, regenerative flesh and an adamantium skeleton for good measure. She even has long adamantium fingernails for five-fingered stabby fun. The single thing she lacks, though, (apart from his pointy haircut and stubble) is perhaps Wolvie’s resourcefulness, as despite getting the better of him during their fight scene in X2, Wolverine manages to send her to a metallic demise by giving her a good pumping (with adamantium).

Ursa – Sarah Douglas

Now for a blast from the past. 1980’s Superman II was notable for many reasons. Among them: men with small beards and mascara, men with large beards and mascara and men without beards and only a dab of mascara. But it is perhaps Ursa – the black-clad babealicious bad girl who really got teenage hearts a-racing (and launched a thousand dominatrix fixations). Plus, she helped to take the attention off Christopher Reeve’s I-put-my-pants-on-the-outside-lol look. Which is always good. Nevertheless, clearly being a total misanthropist, Ursa chose to be BFF with these two guys. Maybe it’s the mascara thing.

Jessica Priest – Melinda Clarke

As the Spawn encyclopaedia SpawnWorld.com describes, even as a kid Jessica Priest was a naughty nipper: “Even from early childhood, Jessica Priest was insane. As a young child in upstate Maryland, Jessica lashed out at her parents when they denied her some marshmallows.” Clearly, her parents’ sugary snack-denial helped to forge Priest’s psychotic side: “But whereas a normal child might have simply thrown a tantrum, Jessica snuck into her parents’ bedroom while they were sleeping, doused their bed with lighter fluid and set it ablaze. In the fire, she killed her parents, pets and burned their house down”. The message here is clear: give kids whatever they want: they have matches. After a turbulent childhood, Priest was later molded by Jason Wynn into an extremely dangerous assassin allowing her to indulge her bloodlust. That was nice of him. Though not nearly as nice as Melinda Clarke’s legs while portraying Ms Priest in the 1997 move adaption of the comic. Not by a long shot.

Poison Ivy – Uma Thurman

One of Batman’s most alluring foes, the floraphile (I might have just made that word up, word fans) named Poison Ivy uses her green-fingered guile to go toe-to-toe with Gotham City’s pointy-eared avenger in 1997’s Batman & Robin. Obsessed with all things botany, she utilizes toxins and pheromones for her evil eco-terrorism – and to good effect, as this deadly orchid has snared more than one man with her poison kiss. Sort of like a member of the Sexy Green Peace Paramilitary Wing then (I just made that up, too). If you are lucky enough to get a date with the flame-haired leafy lovely, remember to take a bottle of calamine lotion with you.

T-X – Kristanna Loken

The laconic T-X is quite the gadget. Designed with a variety of deadly onboard weapons systems, exceptional strength and durability, and (like the T-1000) the capacity to change shape at will, it’s easy to see why the T-X is so darn badass that she’s used as an anti-Terminator Terminator. And luckily for us, this genocidal gynoid assassin is all wrapped up in Kristanna Loken’s sweet, sweet flesh and immortalized on celluloid in (Terminator 3) and paper (Beckett Comics published six comics to help market Terminator 3: Rise of the Machines). As the delectable T-X eventually ‘died’ at Arnie’s hands, does this mean he was an anti-anti-Terminator Terminator?
