Star Trek has given viewers many different aliens across its television shows and movies. Through the franchise’s exploration of different cultures and moralities across the universe, we were almost guaranteed to meet a new alien person or race with each new episode. Often, the alien or alien race would be the subject of only that single episode, but they could make a big impact on viewers and fans. Especially some of the female characters.

While the alien women were confident and intelligent and never afraid to fight their own battles – literally and figuratively – you can see how Star Trek evolved in presenting these women. From revealing costumes (The Original Series mainly) to freedom of choice (The Next Generation), the alien women in Star Trek have had a strange and unique journey.

This list contains some of the most unforgettable aliens in Star Trek, whether they were part of an iconic race or the character only had a role in one episode or movie. There were plenty of steamy aliens to choose from, but the following easily left lasting impressions from their first on-screen minute.

So here’s 15 Steamiest Aliens In Star Trek.

15. Orion Slave Girls

15 Orion Slave Girl 1 15 Most Stunning Aliens In Star Trek

If Star Trek wanted to push the boundaries with steamy aliens early in the series, they did right by the Orion slave girls. These green-skinned beauties were trained primarily to seduce buyers. You typically saw them dancing and flirting.

In the Orion language, their name translates to “life contractors.” While some Orion girls were trained for domestic servitude, the ones you see in The Original Series were trained for other reasons.

Yvonne Craig is perhaps the most well-known Orion slave girl – she also played Batgirl – but in the pilot episode “The Cage,” Susan Oliver took the first role as an Orion girl. The script had mentioned Orion slave girls as “Wild! Green skin, glistening as if oiled.” And after reading that description and then seeing them, we have to agree the description is pretty apt.

14. Amanda Rogers

14 Amanda Rogers 15 Most Stunning Aliens In Star Trek

Playing a Q in the The Next Generation episode “True Q”, Olivia d’Abo brought humility and morality to a character who was part of a race that didn’t hold those things in high regard. Although Amanda Rogers sought knowledge and entrance to Starfleet Academy without revealing who she really was, the original Q (John de Lancie) reveals her identity to the Enterprise crew.

Rogers is cute and charming in the episode – even when she abducts Riker to a romantic 19th century setting because she’s slightly jealous when Riker sits with another woman.

All Rogers wants is a normal human life, but in the end, realizes she’s meant to be a Q and takes her good looks to the Q Continuum – though she promises to visit. Maybe Riker will have changed his mind by then.

13. Arandis

Williams 15 Most Stunning Aliens In Star Trek

Played by timeless beauty Vanessa Williams, Arandis was a Risan woman in charge of an area of the planet Risa. Risa is known as a unique vacation spot for those looking for perfect weather and a perfect lover for a short amount of time. Arandis is a Chief Facilitator, meaning she doesn’t engage in sex as much as those she oversees.

Arandis has the distinction of having sex with Curzon Dax, who died while in the throes of jamaharon (on Risa, this is sex). As you might remember, Dax was a Trill symbiont and subsequently transplanted into Jadzia, a prominent character from Stark Trek: Deep S.

In a way, without Arandis when as a sex worker on Risa, we would never have met Jadzia.

12. Shahna

12 Shahna 15 Most Stunning Aliens In Star Trek

In “The Gamesters of Triskelion” during Star Trek: The Original Series, Shahna the Drill Thrall – played by Angelique Pettyjohn – was James Kirk’s trainer when he and two others were kidnapped and forced to fight in gladiator-like games on planet Triskelion.

Shahna was instantly memorable with her full body of green hair, skimpy metallic outfit, and the powerful emotions Kirk evoked in her. She was torn between her awkward feelings towards Kirk and her loyalty to her duties for the planet’s leaders, the Providers. In the end, like many women on the show, she succumbed to the charms of Captain Kirk.

For those interested on more Shahna after she was liberated, you can read about her as an ambassador in the short story “The Lights in the Sky” from TOS: Strange New Worlds I and Star Trek: The Lost Era novel, Excelsior: Forged in Fire.

11. Kamala

11 Kamala 15 Most Stunning Aliens In Star Trek

Famke Janssen is best known for playing the iconic Jean Grey in four X-Men films. But a few years prior, she had the role of Kamala in The Next Generation episode “The Perfect Mate.”

As an emphatic metamorph, she had special abilities that could sense what a man wanted in a woman and change into exactly that for him. She was the first female born with that ability in over 100 years on her planet. She was betrothed to another man, but had taken a liking to Picard, upon whom she had imprinted on herself. But Picard convinced Kamala to marry the man she was meant for.

What makes Kamala so alluring is partially her emphatic metamorph skills – she can be whatever you want. It also doesn’t hurt that the gorgeous Famke Janssen is portraying the character.

10. T’Pol

10 tpol 15 Most Stunning Aliens In Star Trek

Despite having the unemotional social interaction that Vulcans tend to share, T’Pol enraptured fans. T’Pol started as part of the ship’s crew as a sub-commander, a sort of liaison between Vulcan knowledge of the stars and the Enterprise as it began in exploratory trip. Later she became a Starfleet Commander.

T’Pol usually wore form-fitting uniforms of both Vulcan and Starfleet styles. Jolene Blaylock, the actress who played the character and was a former model, wore those uniforms well. Blaylock played T’Pol with an air of confidence required to pull the character off, since she had access to tons of knowledge Captain Archer and his crew needed as they traversed unknown territory in space.

Commander Charles Tucker once said in an episode that T’Pol “does grow on you.“ With her graceful walk and poise in danger and how stunning she looked in whatever she wore, T’Pol quickly grew on all Star Trek fans.

9. Andrea

9 Andrea 15 Most Stunning Aliens In Star Trek

Androids can be sexy too, right? Not Data from The Next Generation, but Andrea from The Original Series in the episode “What are Little Girls Made Of?” Star Trek has never been afraid to experiment with clothing and costume design and push the limits on female outfits.

For Andrea – played by the exquisite Sherry Jackson – she wore an outfit that was full pants on the bottom, but was basically two strips of cloth crisscrossed in the back like suspenders on top. Her sides were extremely bare, almost revealing more than intended.

Though she did experience confusing emotions when Captain Kirk kissed her, Andrea was basically emotionless, programmed to servitude. Nonetheless, she made a striking impress on viewers.

8. Cadet Gaila

Rachel Nichols as Gaila 15 Most Stunning Aliens In Star Trek

Sometimes a character is onscreen for a short time but makes such an impression based on how much sexiness they added to a scene. This is the case with Cadet Gaila, played by Rachel Nichols, who starred in SyFy’s Continuum.

In the Star Trek reboot of 2009, Cadet Gaila roomed with Nyota Uhura. Gaila slept with lots of people, one of whom was James T. Kirk in Gaila’s first scene. She told Kirk she thought she was in love with him. Kirk only replied, “That is so weird.” Their intimacy was interrupted by Uhuru when she came into the room. Kirk was hidden under the bed, but he eventually revealed himself. Later, Gaila had a quick scene where she was assigned to a Starship.

What made Gaila especially steamy in the movie was the way she lay nonchalantly on the bed talking to Uhuru. Her beauty and confidence were the perfect combination. Did Kirk make a mistake not falling in love with her?

7. Kellin

Madsen 15 Most Stunning Aliens In Star Trek

Virginia Madsen played a Ramuran “tracer” in the Voyager episode, “Unforgetable.” A tracer seeks out those who try to leave the homeworld of Ramuran. Using a special neurolytic emitter, tracers erase the experiences of those who left as if they never did.

While on Voyager, she fell in love with Chakotay and they become close. But when another tracer is sent to bring Kellin home, she has her memory erased of her time on Voyager, telling Chatokay that it’s best if he forgot her.

It’s unfortunate her race’s pheromones make others not remember their interactions. Madsen’s character was fun to watch, her innocence around all the new things she experiences on the ship making her so appealing that fans wanted more of Madsen as Kellin. People didn’t want to forget Kellin anytime soon.

6. Ro Laren

6 Ro Laren 15 Most Stunning Aliens In Star Trek

Ro Laren was in eight episodes of The Next Generation and cemented herself as a much better replacement to Wesley Crusher. Played by Michelle Forbes, Laren was a Bajoran who, coming off a recent court-martial, was placed on the Enterprise-D, much to the objection of Captain Picard. Laren also had no desire to be on the ship, but stayed, stating, “It’s better than prison.”

There’s something likeable about a character that is adversarial to fan-favorite regulars on The Next Generation. Both Forbes and her minor transformation to the Bajoran character are beautiful, even though Ro is a darker character in the series, with some secrets in her past and hardened, no-nonsense interaction with the other characters.

Forbes had played another character in an earlier episode – Dara in “Half a Life” – and when deciding to create a reoccurring character for the fifth season, creators brought back Forbes for the role of Ro Laren. However, when asked to reprise her role for Deep Space Nine, Forbes declined, not wanting to commit to a long-term show.

5. Leeta

Leeta from DS9 15 Most Stunning Aliens In Star Trek

Leeta, played by Chase Masterson, was a Dabo girl at Quark’s in Deep Space Nine. Although Leeta was intended to be in one episode, the show’s producers thought Masterson was so wonderful, they made her a recurring character throughout the last five seasons.

A Bajoran native, Leeta had a strong business sense (she organized a union against Quark and expressed an interest in running her own place), but managed to have men quickly fall in love with her with little effort. Leeta was cute and bubbly, but knew what she wanted as a professional and in her personal life. It appeared that being a Dabo girl was a means to an end for her.

Eventually she married Quark’s brother Rom, and since then only had a strong devotion for him – even before Rom became the Grand Nagus of his homeworld, Ferenginar.

4. Ishara Yar

4 Ishara Yar 15 Most Stunning Aliens In Star Trek

Even though Ishara Yar was a human, she remained behind on Planet Turkana IV when Tasha decided to leave. Ishara was given a chance to leave also, but chose to stay and fight for the Coalition on the planet.

If you hadn’t figure it out, Ishara is Tasha’s sister, though when they separate, Ishara never sees her sister again. When she encounters the Enterprise-D in the episode “Legacy,” Ishara still begrudges Tasha for departing, always considering her sister a coward for doing so. Ishara slowly understands her sister’s motivation and that she was, in fact, a strong woman.

Beth Toussaint played Ishara Yar as a strong woman herself, giving the character an appealing stature as a soldier of the Coalition and a believable emphatic curiosity as she learns about her sister. It’s a shame Ishara was only in one episode.

3. Seven of Nine

Jeri Ryan as Seven of Nine in Star Trek Voyager 15 Most Stunning Aliens In Star Trek

When Kes was no longer going to be part of Voyager, Captain Kathryn Janeway needed a contrasting character according to writers and producers. Whether the new character was to have more sexual appeal for audiences or to provide a different perspective to the human condition is speculative.

Choosing Jeri Ryan – who had no previous knowledge of Star Trek or the Borg – was the right choice. The actress wore a one-piece, form-fitting uniform that Ryan has said on more than one occasion that it was uncomfortable and impractical, but worth it for the character.

Before Seven of Nine became a member of the Voyager’s crew, the Borg costume Ryan wore before that wasn’t measured correctly and caused her to pass out because her carotid artery was pinched, cutting off blood supply. Ryan passed out two times. Eventually, she came to wear the jumpsuit fans have come to know and love.

2. Saavik

2 Saavik 15 Most Stunning Aliens In Star Trek

Kirstie Alley’s movie debut was Lieutenant Saavik in Star Trek II: The Wrath of Khan. For this part, Alley was nominated for a Saturn Award for Best Supporting Actress. She played a half-Vulcan, half-Romulan Lieutenant who had just graduated Starfleet Academy and assigned to the Enterprise when Khan attacked the ship.

With some of Saavik’s dialogue and a few scenes cut from The Wrath of Khan, her backstory is unclear. Much of Saavik’s past is retold in books and comics, but those are not considered canon. It is believed that during one of Spock’s pon farr episodes – a moment for a Vulcan where they must mate or succumb to the intense emotion – Saavik helped him through it. The movie’s writers had planned to have her pregnant with Spock’s child, but they never had a chance to explain this in the film.

For subsequent films, Alley was asked to continue as Saavik, but because she wanted more money for a small role, she was replaced by another actress.

1. Deanna Troi

1 Deanna Troi 1 15 Most Stunning Aliens In Star Trek

Deanna Troi is the Enterprise’s ship’s counselor in Star Trek: The Next Generation. As a Betazoid empath, she can gleam emotions from others to determine mood, motives, and possible future actions. Marina Sirtis brought a subtle sexuality to the character over the seven seasons, only enhanced by the uncharacteristically-Starfleet outfits she wore.

Sirtis wore tight-fitting unitards, like many of the actors and actresses in the show, but the tops of hers tended to be low-cut, allowing her cleavage to be very visible. Combine that with Sirtis’s amazing beauty and you have two great reasons she’s added to a list like this. The only episode Troi did not show her cleavage was the pilot, “Encounter at Farpoint”; she wore an official skirt-like uniform like the women did on Star Trek: The Original Series.

Originally, the character of Deanna Troi was to have four breasts according to the book Gene Roddenberry: The Myth and the Man Behind Star Trek. Would that have made Troi steamier?
