15 Hottest Sci-Fi/Fantasy TV Couples


There are many reasons to watch sci-fi and fantasy TV shows. Some of us love escaping to other worlds and checking out cool technology or mythical monsters. Some of us, though, just like to see our favorite characters get together!

There is no shortage of awesome couples in sci-fi and fantasy television. But we have assembled the definitive list of hottest genre couples. Keep reading to see if your favorite couple made the list!

Buffy Summers & Angel

In Buffy the Vampire Slayer, the titular hero would have more than one love of her life over the course of the series. But nothing was ever quite as hot as her forbidden relationship with the vampire Angel. She was sworn to kill monsters, and he would turn evil if they consummated their relationship, but these two did their best to make it work.

Jon Snow & Ygritte

“You know nothing, Jon Snow!” This iconic catchphrase from Game of Thrones’ Ygritte quickly became a cultural touchstone. It was bittersweet watching the doomed onscreen relationship between Jon and Ygritte, but it had a happy ending when the actors, Kit Harington and Rose Leslie, ended up marrying in real life. They revealed the birth of their first child, a son, in February 2021.

Eric Northman & Sookie Stackhouse

In True Blood, audiences were nominally meant to root for southern belle Sookie to end up with vampire Bill. But it was tough to deny how hot the mysterious vampire Eric Northman was, and series fans went crazy when he and Sookie hooked up. 

Malcolm ‘Mal’ Reynolds & Inara Serra

The relationships in Firefly were unconventional, to say the least. For example, Captain Malcolm Reynolds often tossed insults to crewmate Inara because she was a Companion… basically, a government-approved prostitute. But their barbs and banter hid deep feelings of respect and love they had for each other, and fans began shipping these characters right away.

Buffy Summers & Spike

Arguably, the greatest love of Buffy Summers’ life was Angel. But fans loved bad-boy vampire Spike from the beginning, and he became a regular character in Season 4. Buffy eventually hooked up with him in Season 6, and even though the relationship ended in a horrific manner, we can’t deny that their (quite literally) house-shattering hookup was hot to watch.

Clark Kent & Lois Lane

In Smallville, Clark Kent had multiple compelling relationships, including one filled with “will they, won’t they” tension between him and Chloe. But one of the best parts of the series was that we got to see the relationship between Clark and Lois Lane, the love of his life, develop over time. And the great onscreen chemistry between the actors made each moment sizzle.

Khal Drogo & Daenerys Targaryen

One of the best descriptions of Game of Thrones is “problematic.” As great as the characters and stories are, audiences were sometimes compelled by some really problematic pairings. This included Khal Drogo basically buying Daenerys Targaryen as his wife. That sounds terrible, but the two eventually developed a deep relationship, and scenes between them nearly set our TV on fire.

William Riker & Deanna Troi

William Riker and Deanna Troi had one of the most complex relationships in Star Trek: The Next Generation. That is because the characters once had a passionate affair before the series began and then spent most of the show trying to keep things professional. But across some lackluster movies, we see these two rekindle the flame and even get married (which was one of the only good things in Star Trek: Nemesis, BTW).

Amy Pond & Rory Williams

The fifth season of the 2005 Doctor Who threw us for a bit of a loop. For example, it was obvious that companion Amy Pond had both chemistry and romantic tension with The Doctor. But her heart still beat for Rory Williams, and his love for her helped transform him into an unlikely hero. And it’s tough not to tear up while watching their relationship literally transcend all of space and time!

Kara Thrace & Lee Adama

In the rebooted Battlestar Galactica, there was an early tension between Kara Thrace and Lee Adama. She had dated Lee’s now-deceased brother and now enjoyed a better relationship with Lee’s dad than Lee himself did. We see their bond grow stronger over the series, and the sexual tension between these two is more relentless than any Cylon attack.

Xena & Gabrielle

Television censors didn’t let us see much of an explicit relationship between Xena and Gabrielle, but it was clear they were meant to be a couple. Any fan can only watch so many scenes of these two sleeping next to each other and bathing together to figure this out. And the clear chemistry between these characters helped transform Xena and Gabrielle into early gay icons.

Mulder & Scully

Yes, Virginia: Mulder and Scully became a couple, though we can forgive any casual fan that didn’t know that. After all, most of their actual relationship occurs offscreen, including both hooking up and breaking up. While that sucks, it doesn’t invalidate all of the hot tension these two share for most of the series (or, you know, that dance at the end of the black and white episode that always stops our hearts).

Cersei & Jaime Lannister

Remember when we said that Game of Thrones was filled with problematic relationships? Perhaps the best example of this is Cersei and Jaime Lannister, the brother and sister with benefits. Everything about their relationship should seem icky and weird, but the sheer charisma and chemistry between actors made this coupling oddly hot. 

Jessica Jones & Luke Cage

Jessica Jones is one of our favorite Marvel characters. After all, the idea that a superpowered person hung up her cape to live as a world-weary detective is just too perfect. Also perfect is her relationship with Luke Cage. They each have baggage and trust issues, but they also have bed-breaking sex, and even the most cynical fan has to admit these two belong with each other.

Zoe & Hoban ‘Wash’ Washburne

Part of what made Firefly fun is that the show subverted our expectations, especially when it came to relationships. Take Zoe and Wash, for example. Rather than reinforce traditionally male/female gender dynamics, the show made Zoe into a battle-hardened warrior and her husband into a meek pilot who would rather play with toy dinosaurs than throw a punch. But opposites really do attract, and audiences were instantly attracted to the love and mutual respect of this power couple.
