Alias: Henry Cavill
Partner in crime: Kaley Cuoco
Superman found his Lois Lane in Cuoco, whose luminous blonde locks may be just as powerful as kryptonite for the Man of Steel stud. "They were both single and started dating recently," a source close to the actor tells PEOPLE of the new couple, who first became linked this month. "It's just the beginning stages of a relationship, and they're having a great time."

Alias: Andrew Garfield
Partner in crime: Emma Stone
You don't need Spidey Sense to detect the chemistry between The Amazing Spider-Man's reel-to-real-life couple. Before linking up in 2011, "We read a couple of scenes together," Stone, who plays Gwen Stacy, told MTV News in 2012. "You can sense if you guys have a kind of chemistry or rapport right away. No matter what the relationship is, whether it's a love interest or not."

Alias: Ryan Reynolds
Partner in crime: Blake Lively
We're green with envy just looking at Lively's heroic hunk, who transforms into a member of the Green Lantern Corps (and Lively's on-screen love interest!) in the 2011 DC Comics screen adaptation. "To get to rival the hero is something so unique," the actress, who married her masked man in September 2012, said of the role. "It was a really nice dynamic."

Alias: Halle Berry
Partner in crime: Olivier Martinez
Berry's superpower? An enviable ability to fill out a curve-hugging bodysuit and make even a white-colored wig look sexy. The X-Men bombshell will save the day again when the franchise's next installment, X-Men: Days of Future Past, arrives in theaters in May 2014, but in the meantime she's ready to tackle a different challenge: welcoming her first child with fiancé Martinez.
5 of 8
Alias: Chris Hemsworth
Partner in crime: Elsa Pataky
It took 20 lbs. of muscle for Hemsworth to fill out his armor – so it's no surprise that he was strong enough to sweep wife Pataky off her feet. We're guessing Hemsworth, whose follow-up, Thor: The Dark World, arrives in theaters this November, won her over with his own secret weapon – his heart-melting gaze! – as opposed to his magical Mjolnir hammer.
6 of 8
Alias: Anne Hathaway
Partner in crime: Adam Shulman
In 2012, Hathaway took a trip to the dark side as Selina Kyle (a.k.a. Catwoman) in Christopher Nolan's 2012 The Dark Knight Rises. Although the skintight suit fit purr-fectly – despite being "a psychological terrorist," she joked – the actress traded it in for a custom Valentino gown for her September wedding to actor-jewelry designer Adam Shulman.

Alias: Robert Downey Jr.
Partner in crime: Susan Downey
No amount of hardware could keep wife Susan away from the Iron Man actor, who first suited up in the Marvel Comics superhero series in 2008, about three years after they walked down the aisle. And although the Avengers star is the one kicking butt, she "has got me in a freakin' choke chain," Downey told PEOPLE back in 2003. "And I love it."
8 of 8
Alias: Hugh Jackman
Partner in crime: Deborra-Lee Furness
It's not easy taming the Wolverine, Jackman's scruffy Marvel Comics alter-ego, whom he first channeled in 2000's X-Men. "I've almost been pummeled as people try to get to him," Furness, who wed the actor in 1996, told the New York Post in 2011. "Literally, they will push you out of the way," which tempts her to say, "Hi, I'm chopped liver. How do you do?"
