26 Sci-Fi Studs and Stunners

Leia may say she likes nice men, but we all know no one can resist the magnetic attraction of this scoundrel. A cynical smuggler with a heart of gold, he's never afraid to tell it like it is. Plus, he's the hottest, stuck up, half-witted, scruffy-looking Nerf herder in the galaxy. —Maricela Gonzalez

She may be sent into different worlds on engagements, but the only engagement we want to see is one between Echo and viewers. We also wouldn't say no to some alone time in the Dollhouse. — Erin Strecker

Before Transformers, did any of us really know women like Megan Fox existed? Even putting aside her obvious assets — those eyes, those lips, that voice — she just oozes smoky and sexy. Oh, and when she popped the hood on that Camaro and started checking out the engine...let's just say we've never wanted to be a Transformer more than at that exact moment. —Deven Persaud

NBC's superhero serial certainly wasn't short on eye candy, but nobody smoldered quite like brainy Mohinder — a genetically gifted genetics professor who didn't gain special powers until season 3. (He still counts for this humans-only list, since we like to pretend seasons 2-4 never happened.) —Hillary Busis

There can be only one reason Jake (Sam Worthington) didn't develop a crush on kick-ass pilot Trudy — he was asleep almost the entire movie. —Lanford Beard

There's no way Chris Carter gave his extraterrestrial-obsessed FBI agent that first name by sheer coincidence. There. The truth is out there. —Lanford Beard

The only thing sexier than a lone survivor who loves his dog is a lone survivor who loves his dog and has a body that's more solid than the ground he walks on. —Samantha Highfill

You better look like Denise Richards if you're going to play a selfish careerist who breaks her sweet boyfriend's heart. We're not even saying Johnny Rico (Casper Van Dien) was wrong to enlist for her. We saw her in those fatigues. —Lindsey Bahr

All respect to Zoë Saldana, but Nichols' Uhura is the O.G. of final frontier fierceness. She and Captain Kirk (William Shatner) didn't just break the sound barrier, they broke down racial prejudice as the first interracial kiss on television. —Lanford Beard

Despite Jin's language barrier and constant frustration in early seasons, he eventually captured our hearts with his devotion to Sun (Yunjin Kim) and his loyalty to the survivors. Plus, we wouldn't mind getting stranded on a mysterious Island with him if he looked like this every day. —Shirley Li

As played by Piper, Rose was a helplessly average person who turned out to be extraordinary — a local girl at home in the furthest reaches of time and space, capable of hobnobbing with royalty, someone generously trying to understand even the most terrifying alien monsters. Given her layered, if all-too-brief romance with the Doctor, we understand why he would tear apart space and time to save her. —Darren Franich

Given his association with vampires, werewolves, doppelgängers, witches, and who knows what more, Matt probably should have died a long time ago. But he's just so gosh darn pretty! We like to think the showrunners keep him around just for us. —Maricela Gonzalez

Loyal, practical, measured Astrid helps to ground longtime BFF Stephen (Robbie Amell), who discovers he's a superpowered ''tomorrow person'' in this upcoming CW series. She also boasts the fall TV season's most glorious hair. —Hillary Busis

Thanks to her form-fitting white jumpsuit, women want to be Cora, men want her inside them — strictly for scientific purposes, of course. —Lanford Beard

With Organa's royal heritage, think of him as a geek Prince Charming. Smits has long been Earth's go-to hot guy. Enshrouded in power as Star Wars' senator from Alderaan, he took his stud cred to intergalactic levels. —Lanford Beard

Like Peter (Joshua Jackson), we'd take Olivia in any universe — especially if she's wearing that foxy film noir look from ''Brown Betty''. —Lanford Beard

Compared to the grotesque kaiju, even the blandest human would be a stud but Marshall Pentecost outranks monsters and humans alike in leadership, class, and hotness. We would gladly marshal on the fight to ''cancel the apocalypse'' by his side — if only to see him don that body-hugging armor. —Maricela Gonzalez

Jason Stackhouse gets more action than anyone in Bon Temps (vampires included), and it has absolutely nothing to do with his intelligence or, for that matter, what he looks like — with his clothes on. —Samantha Highfill

Three words: Skintight Vinyl Jumpsuit. Do you really need to know anything else about the brilliant, anarchic badass? —Lindsey Bahr

Can you blame the Terminator? If we met a man with this much gun power, we'd be back, too. —Lanford Beard

President Roslin had the unenviable job of leading the survivors after the Fall of the Twelve Colonies while suffering from terminal breast cancer. But her fearlessness, eloquence and all-around badassery made her absolutely frakkin' sexy — something Admiral Adama (Edward James Olmos) certainly noticed. —Shirley Li

He may not be the most trustworthy character on this list, but the dashing British businessman certainly wears a suit the best. —Lanford Beard

In Gattaca's genetic dystopia, even Uma Thurman is imperfect. Thankfully as the audience we can laugh off her anxieties and marvel at the drop dead gorgeous Irene, especially when she lets her Veronica Lake locks down for a night out. —Lindsey Bahr

This well-dressed man of our dreams stole our hearts in Christopher Nolan's mind-bending thriller. This smooth talking conman is someone who can play an innocent prank as well as handily use a grenade launcher. The forger has even inspired a plethora of fan fiction — often co-starring the equally debonair Arthur (Joseph Gordon-Levitt). —Maricela Gonzalez

Sure, she strips down to her knickers in the first film's final confrontation, but Ripley's real sexiness is in her unflinching bravery in the face of slavering acid-blooded space beasts. Plus, as Alien 3 proved, she can even rock a buzz-cut. —Keith Staskiewicz

Dean's sense of humor and overall protective nature toward younger brother Sam both make him incredibly alluring. Add in those eyes and that physique, and Dean has us hoping our bedrooms are haunted if only to give him a reason to visit. —Samantha Highfill
