The 12 Most Twisted Sex Scenes In Sci-Fi History

Science fiction has never been known as a particularly titillating genre. But people in science fiction do get down and dirty (as people are wont to do), and some of those sci-fi sex scenes can get incredibly twisted. We’re not just talking about interspecies copulation (though there are plenty of instances of that throughout). No, there’s some pretty crazy emotional stuff that goes down in some of these scenes. These go beyond hurt feelings: some of the scenes can get truly insane.

Sure, Star Trek has its share of strange sexual encounters (all of them awkward), but many horror filmmakers use science fiction to explore taboos in ways other genres can’t touch. With enough imagination, you can create scenarios that will stay with audiences for decades. Decades. You can probably think of a few right now, but you’re about to discover some more examples that will haunt your psyche forever. So, if you ever wanted to see otherworldly sex that involved robots, gene-splicing, inbreeding, and time travel you came to the right place. 

From the opening scene to the second the credits roll, this is essentially one long screwed up illicit adventure. Seriously, basically every major character gets busy with every other major character in every possible combination. Oh, and that’s on top of playing God with a mechanical womb and gene-splicing technology.

See, this young scientist couple creates an animal/human hybrid (ostensibly for medical research, mostly just to see if they can). They begin to raise the creature as their daughter, which makes it super creepy when the male scientist hooks up with her. Remember, she’s part-animal.

The craziest part, though? It’s eventually revealed that the female scientist used her own DNA to create the hybrid. The creature, previously female, changes genders and proceeds to assaulted its creator. So, yeah, she got assaulted by her own daughter/son/frog monster. And yes, it’s just as disturbing as it sounds.

The first time you watch The Fly, it really doesn’t seem like a horror movie. But around the halfway point, Jeff Goldblum strolls into a bar, breaks a guy’s hand off in an arm wrestle, and picks up some random woman. That’s when you start to realize things are going very, very wrong.

When they get intimate, there’s an animalistic look in his eye that’s very… off-putting. It’s right here you know he’s losing himself, and it makes the scene anything but sexy. Also, the implications of their union is pretty terrifying in its own right. The viewer knows that Goldblum is well on his way to becoming a man/fly hybrid. So, uh, what is going on with his genetics then, exactly? Did he give this woman some sort of weird fly-based STI? Or will he just impregnate her with a terrifying monster-child? Neither option seems great.

On paper, the plot of Species sounds pretty much exactly like a movie you would find in the adult’s only section. It is, however, a big budget Hollywood movie. Basically, the movie is about a female alien/human hybrid who escapes her captors and really wants to mate. Her desire to find a baby daddy leads her to LA, where she seduces a guy and they start going at it in his pool.

When he isn’t too thrilled with the idea of having a kid, she forces him into the pool and goes to town on him with tentacles. If you look close, one of those tentacles is actually coming out of her breast. Yikes.

Kane And The Facehugger In Alien

If you think about it, Kane getting impregnated by a facehugger is definitely an “adult” scene. An experiment: try to describe what the alien is doing to his face without using overly explicit terms. You can’t do it For the three humans on the planet that haven’t seen Alien, context doesn’t really make the scene less weird. Like at all.

So Kane of the spaceship Nostromo is checking out an alien vessel. He finds some slimy eggs (probably a good time to run away, but whatever), and a creature called a facehugger attaches itself to his face and impregnates him with an alien baby that later bursts out of his chest. Essentially, then, you’re watching a cross-species interstellar assault. Basically, you’ll probably want to skip Alien on movie night with your parents from now on.

A bizarre sexploitation film starring the incomparable Jane Fonda, Barbarella is about a sexually inexperienced astronaut living in the 41st century. While on a quest, pretty much everyone she comes into contact with is incredibly horny. Also, for some reason, she’s into it.

In a film full of crazy moments, the standout has to be when she’s strapped into the “Excessive Machine,” a device which produces climax so strong it kills whoever is inside it. But, of course, Barbarella is so insatiable that she ends up breaking the machine and surviving.

Rygel And John In Farscape’s “Won’t Get Fooled Again”

While this technically isn’t a full-on intimate moment, it’s frankly too bananas not to discuss. John Crichton, wayward astronaut stuck in deep space, is mentally tortured by an evil race called the Scarrens. They put in him crazier and crazier situations in an effort to drive him insane so his mental defenses will drop.

One of those many visions involves him being handcuffed to a hospital bed where a muppet in bondage gear whips him. So, yeah, that made it on to television. Seriously, this one is either super funny or the most terrifying thing ever done to a human being. One of the two.

Data And The Borg Queen In Star Trek: First Contact

Data gets a surprising amount of romance, considering he’s supposed to be an emotionless android. After all, he is “fully biologically functional.” But one of the strangest (and most revolting) encounters occurs in Star Trek: First Contact.

The Borg are taking over the Enterprise (since they’re kind of d*cks like that), but they need the encryption codes to break into the main computer. Data, of course, has these codes. Thus, the Borg Queen decides to seduce Data by not only getting it on with him, but giving him fleshy upgrades so that he can feel the pleasure better. Ick.

Six And Baltar In Battlestar Galactica’s “A Measure of Salvation”

Baltar and Head Six have some pretty fantastic (and humorous) scenes in Battlestar Galactica. The fact that she’s in his mind means she can appear any time, including when he’s having a conversation with someone else.

In the case of this particular episode, Head Six transports Baltar to a sandy beach while he’s being tortured. To help him cope with the pain, Head Six lays Baltar out and starts to ride him. Mid-coitus, she coaches him on exactly what to say to manipulate his torturer. That’s some serious manipulation right there.

Ellen Tigh And Cavil In Battlestar Galactica’s “Occupation”

While there are, like, a million characters on Battlestar Galactica, perhaps none drew as much ambivalence as Ellen Tigh. Reviled for most of her run on the show as a cheating wife and a drunk, Ellen used those qualities to save her husband during the Cylon occupation of New Caprica.

After her husband Saul Tigh was captured and imprisoned, Ellen caught the attention of a Cylon named Cavil. She slept with him (repeatedly) to secure her husband’s release and freedom. This is really only messed up in retrospect. See, later in the show it’s revealed that Ellen is a Cylon who created Cavil based on her father. Oh, and Cavil knew the whole time. That’s some pretty twisted stuff right there.

Data And Tasha Yar In Star Trek: The Next Generation

There’s nothing wrong with Data getting a little bit of action. It’s just the way this scene goes down that’s just wrong in every conceivable way. Not only is Tasha Yar under the influence of a virus that affects her judgment, but she’s propositioning him while reminiscing about running from gangs that tried to assault her as a minor. Like, way to set the mood Tasha.

It’s pretty much a red flag for a non-consensual situation. But, of course, Data doesn’t know any better… so he hooks up with her. The worst part is the bizarre smirk on his face while she leads him into the bedroom. Have fun trying to not picture that when you close your eyes.

Okay, this isn’t here because it involves two blue aliens gettin’ it on. Sure, it’s strange because instead of “getting to know each other” the way we humans might, they use the same biological function they use for riding animals. Wait, does that mean Jake intimately knew all of those many-legged horses? Whatever, that’s not the point.

What’s really twisted here is that Jake gets with Neytiri for the first time while he’s spying on Na’vi society. While he’s trying to figure out how to set up their relocation, he’s also banging the chief’s daughter. Gross move, Sully. Gross move.
