15 Greatest Characters In American Sci-Fi Shows

Science fiction shows are known for having complicated stories, detailed histories, and surprising twists. However, relatable characters are what truly make these shows work, reminding us that even in fantastical settings, these are stories about people and their experiences. Well-developed characters give the plot meaning, and the extraordinary worlds around them actually emphasize what makes those characters human.

James ‘Sawyer’ Ford quickly became a beloved character on Lost. He wasn’t just defined by his intriguing past, but also by his unique personality, which helped keep the show grounded in its characters even as the storyline became more complex.

Like many long-running shows, Stranger Things grew in scope over time. However, Winona Ryder’s character, Joyce Byers, always kept the central story grounded: the search for a missing boy in a small town.

While strong world-building helps a series become memorable, it was the deeply emotional characters in these sci-fi shows that truly made them iconic.

15. Molly Cobb

For All Mankind

The show For All Mankind takes the real science of the space race and imagines ‘what if?’ – making it science fiction in its purest form. It smartly avoids overcomplicating things, showing how even small changes to history can create big consequences. This is perfectly illustrated by the character Molly Cobb, who is based on the true story of astronaut Jerrie Cobb.

In this version of events, Molly Cobb truly shines, revealing her incredible skills, compassion, and bravery. Skillfully played by Sonya Walger, known from Lost, Molly Cobb powerfully demonstrates what can be achieved when women and minorities are given the opportunity to thrive in positions of influence.

14. Jeevan Chaudhary

Station Eleven

From the start, the unlikely pairing of Jeevan and Kirsten made Station Eleven stand out. The idea of a stranger suddenly becoming responsible for a young girl when the world ends was immediately captivating. But what truly made Station Eleven special was that Jeevan was just as unprepared for the challenge as anyone would realistically be.

While Station Eleven focused on Kirsten’s journey, the series also did a great job of showing Jeevan’s struggles, making him a sympathetic and relatable character. The show delved into his past and personality, seamlessly explaining how he became the person we see in the post-apocalyptic world, making him a truly unique and memorable character in science fiction.

13. Cooper Howard

Fallout

The show Fallout brilliantly contrasts the Ghoul with Cooper Howard, his pre-war self, to illustrate how the harsh post-apocalyptic world destroys people both physically and emotionally. Cooper’s story becomes increasingly heartbreaking as we learn more about his past, especially in season two when it’s revealed he unknowingly played a role in the catastrophe that destroyed his family.

While flashbacks help us connect with the Ghoul, Walton Goggins’ powerful performance is truly what makes the character so compelling. Even with a scarred face, Goggins conveys a wealth of emotion, especially the Ghoul’s deep pain over losing his family and his sincere feelings for Lucy. This makes it easy to sympathize with him, even though he claims he’s not a hero.

12. Carol Sturka

Pluribus

Rhea Seehorn, known for her role in Better Call Saul, carries the show Pluribus almost single-handedly. She brings both humor and believability to the strange circumstances, and although some viewers find her character unlikeable, her flaws are rooted in past trauma – both from the show’s central event and from her life before it.

The show Pluribus occasionally suffered from a slow pace, something creator Vince Gilligan was often criticized for. However, Carol’s portrayal of loneliness is both captivating and deeply moving. The more complicated and divisive her character becomes, the more compelling it will be to watch her ultimately save the day.

11. George Jetson

The Jetsons

Even today, The Jetsons is impressive thanks to its appealing look and thoughtful themes. The show’s retro-futuristic style is fun to watch, but the design of Orbit City was more than just visually interesting. The towering buildings weren’t just about creating a spacious and open feel—they were a practical solution to the pollution on the ground.

The show often hinted at a culture of overindulgence, laziness, and having an unwarranted sense of importance. This was especially clear with George Jetson, who, despite only working one hour, two days a week, was portrayed as a typical stressed-out working father, hilariously bothered by everyday problems and minor annoyances.

10. Kevin Garvey

The Leftovers

Kevin Garvey isn’t a flashy or immediately captivating character, especially when compared to others on the show. However, this subtlety is precisely what made him such a strong lead in The Leftovers. The series began with the mysterious disappearance of two percent of the global population – an event called the Great Departure – and things only became more unusual from there.

Kevin, a good-hearted sheriff and father, unexpectedly became the focal point of both the chaotic reactions to a strange event and a larger, mysterious purpose. As the show, The Leftovers, progressed, it essentially asked Kevin, an ordinary man, to save the world, and the fact that he was chosen for this task without any obvious reason was a central theme the show wanted viewers to consider.

9. Mark Scout

Severance

Although the first season of Severance was almost flawless, the second season truly elevated the characters and storyline. The intriguing mysteries surrounding Lumon Industries were compelling, but it was the realistic and heartbreaking portrayal of Mark Scout’s grief after Gemma’s death that helped viewers understand his decision to undergo the ‘severance’ procedure.

Adam Scott’s acting powerfully showed Mark’s inner turmoil. The season 2 finale, “Cold Harbor,” featured some of his best work yet, and surprisingly showcased his ability as an action hero. While full of exciting action, the episode also included a deeply emotional scene where Mark had a conversation with himself – a pivotal moment for his character and the show.

8. Hoban “Wash” Washburn

Firefly

The short-lived but much-loved space western Firefly featured a fantastic cast, and Alan Tudyk’s character, Wash, was a standout. He brought a genuine warmth that perfectly suited the show’s unique tone. Firefly skillfully combined the spirit of the Old West with a gritty, post-war industrial setting, and the show’s space-based setting amplified the emotional impact of everything that happened.

Wash was driven by a simple, beautiful goal: to see the stars, something he couldn’t do on his polluted home world. Combined with his heartfelt love for his wife, Zoe, this made him a truly lovable character. His death in the movie Serenity, a continuation of the Firefly series, deeply impacted fans and helped revitalize the franchise.

7. Gaius Baltar

Battlestar Galactica

As a critic, I’ve always appreciated how Battlestar Galactica explored gray areas, and Gaius Baltar was central to that. He wasn’t just a villain, or even a hero; he was frustratingly, brilliantly human. He made terrible choices, but you could also see his heart, and that really forced you to think about when looking out for yourself crosses the line into selfishness. He was a complicated character, and that’s what made him so compelling.

James Callis’s performance was key to bringing the show’s complicated themes to life, adding both emotional depth and pure enjoyment. This was also helped by strong writing, which gave Baltar a fitting conclusion by bringing his story full circle and returning him to his simple beginnings as a farmer.

6. G’Kar

Babylon 5

G’Kar and Londo were a fantastic pairing on television, but G’Kar stood out as a strong character on his own. Initially presented as a comedic villain, G’Kar underwent a genuinely moving transformation throughout Babylon 5. This journey also created a compelling and often humorous relationship with Londo, becoming a highlight of the show.

Babylon 5 delved into complex political ideas, examining how people form their identities and loyalties. However, the character G’Kar also emphasized the importance of the individual. His decision to forgive Londo demonstrated his capacity for independent thought, even while remaining deeply connected to his Narn heritage and culture.
