Star Trek: Discovery, an amazing addition to the iconic Star Trek universe, has taken us on a thrilling interstellar journey ever since its debut in 2017. Set roughly a decade before the original Star Trek series, it has redefined what it means to explore strange new worlds and seek out new life and civilizations.

It’s a series that boldly goes where no Star Trek series has gone before, intertwining classic Trek elements with fresh and modern themes.
At the heart of Discovery is its dynamic and diverse cast, each bringing their unique perspectives and backgrounds to the Starfleet table. Characters in Discovery are not just crew members aboard a starship; they are intricate individuals, each with their own struggles, triumphs, and journeys.

Their interactions and growth provide not just entertainment but also thoughtful commentary on contemporary issues.
Let’s take a look at all our favorite characters and where they fall when it comes to their fellow crewmates.
Let’s fly.

13. Airiam
Airiam, the cybernetically-enhanced officer aboard the USS Discovery, not only captivates us with her unique blend of human and technological elements but also touches our hearts with her ultimate sacrifice.
Her distinctive appearance and the hint of an untold backstory draw us into her world, a world that remains shrouded in mystery as we continue going on adventures with the Discovery crew. Airiam, existing at the crossroads of technology and humanity, embodies a storyline brimming with potential in the Starfleet universe but the series only offers glimpses of her full narrative, leaving us yearning to uncover more of her hidden depths.
Amidst her more subtle role, Airiam’s presence adds an important layer to the crew’s dynamics. Her final act of selflessness, sacrificing herself for the safety of her crew mates, elevates her from a background character to a memorable and heroic figure. Her serene and mysterious demeanor, paired with this brave act, deepens our intrigue about what we could have found out about her and her past. Airiam’s character, with its unexplored potential and noble end, invites us to imagine the possibilities and untold tales within the Star Trek universe.
In Star Trek: Discovery, Airiam stands out as a character whose quiet strength and sacrifice resonate with us, reminding us of the profound stories of bravery and selflessness that lie at the heart of the Star Trek saga.

12. Joann Owosekun
Joann Owosekun, affectionately nicknamed “Owo” by her USS Discovery crewmates, stands out as another beacon of untapped potential in the Star Trek: Discovery universe. As a bridge officer, Owo embodies a blend of quiet strength and steadfast reliability, confidently managing her responsibilities with an ease that underscores her competence.
What makes Owo particularly intriguing is the rich lore behind her background, rooted in a Luddite collective. This facet of her character offers a delightful paradox: a life that began in a technology-refusing environment, now flourishing in an environment full of space-age tech. This contrast between her past and present isn’t just a mere character detail but a gateway to a ton of stories waiting to be told, offering a unique perspective on the intersection of tradition and progress.
Envision the captivating episodes that could have delved deeper into Owo’s narrative: her personal challenges, her victories, and perhaps the internal tug-of-war between her original values and the principles of Starfleet. While we catch glimpses of her impressive physical prowess and tactical smarts, there’s an unmistakable sense that these traits are merely the beginning of what Owo has to offer.
With her subtle yet undeniable resilience, Owosekun had the makings of a standout figure, one who could bring both depth and a fresh viewpoint to Star Trek. Her character is like an uncharted star system in the vast Trek universe: partially explored, with countless mysteries still to unravel, leaving fans eager and yearning for more.

11. Keyla Detmer
Every so often, there are characters on TV that intrigue us with a sense of mystery. We don’t know much about them, but we want to get to know them. That’s where this next character comes in.
Keyla Detmer, the helmswoman of the USS Discovery, presents an intriguing blend of mystery and mastery in Star Trek: Discovery. Wearing a distinctive cybernetic eye implant, she stands out not just for her unique appearance but for her exceptional piloting skills. Picture Detmer at the helm, her hands effortlessly guiding the ship through the vastness of space, weaving through nebulas and dodging asteroids with the finesse of an astronomical ballet dancer. Her role is crucial, yet it’s her quiet, understated presence that leaves fans yearning for more.
Detmer’s past, particularly the story behind her cybernetic enhancement, is a canvas waiting to be painted. Viewers see her as calm and competent, but the depth of her experiences, the challenges she’s faced, and the journey she’s traveled to become the officer we see each episode remain shrouded in secrecy. This aura of mystery makes her fascinating. She’s more than just a crew member; she’s a vault of untold tales, a character whose every appearance on screen prompts many questions.

10. Jett Reno
Played by one of my all-time favorite comedians, Tig Notaro, Jett Reno is a character who lights up the screen with her quick wit and no-nonsense attitude and she also has a delightful presence in Star Trek: Discovery. Although she may not be at the very heart of the main plot, Reno’s role is like a dash of spicy seasoning in a well-prepared dish – it’s not the main ingredient, but it sure adds a memorable kick. With her sharp one-liners and a pragmatic approach to problem-solving, she brings a refreshing and relatable touch to the high-stakes world of space exploration.
Reno’s interactions with other crew members are a source of both humor and insight. She’s the kind of person who says what everyone is thinking but is too polite to voice. This straightforwardness, combined with her undeniable technical expertise, makes her an unsung hero aboard the Discovery.
Whether she’s fixing a critical piece of equipment or offering a sarcastically witty comment, Jett Reno is a character that adds a unique and enjoyable flavor to the series. Her presence reminds us that even in the far reaches of the galaxy, a little humor and down-to-earth practicality go a long way.

9. Christopher Pike
Christopher Pike, portrayed by the ever gorgeous Anson Mount with a perfect blend of charisma and authority, truly stands out in Star Trek: Discovery. As the captain of the USS Enterprise, Pike is a beacon of leadership and moral clarity in a universe often lurking with complex ethical dilemmas. His presence on the show brings a refreshing throwback to the classic Star Trek values of honor and exploration, making him a favorite among fans who cherish the series’ roots, and propels him and his Enterprise crew into the amazing show that is Star Trek: Strange New Worlds.
What makes Captain Pike so appealing is not just Anson’s looks and expressions his unwavering commitment to doing what’s right, even when the path is full of challenges. He navigates through the turbulent waters of space diplomacy and interstellar conflicts with a calm and principled demeanor, embodying the ideal Starfleet officer.
His interactions with the crew of the Discovery, especially in mentoring and guiding them, highlight his exceptional leadership qualities. Pike’s ability to balance firm decision-making with genuine care for his crew not only cements his status as a memorable character but also serves as a shining example of what it means to lead with integrity and courage in the face of adversity.

8. Adira/Gray
Adira, played brilliantly by Blu del Barrio, and Gray, portrayed by Ian Alexander, are two characters who brought a whole new dynamic to the Star Trek universe. Adira, as a human joined with a Trill symbiont, Tal, is a walking, talking archive of memories and experiences from previous hosts. They’re super smart, a bit quirky, and have a knack for solving complex problems – think of them as a puzzle master. Their storyline is not just about space adventures; it’s a heartfelt journey of self-discovery and acceptance.
Then there’s Gray, Tal’s previous host and Adira’s beloved. Gray’s presence, initially as a supportive ghost-like figure only visible to Adira, adds a layer of emotional depth to the show. His storyline beautifully explores themes of identity and belonging, resonating with many viewers. When Gray gets a chance to interact with others, his warmth and charm shine through, making him a memorable part of the Discovery crew. Together, Adira and Gray represent love, resilience, and the power of being true to oneself, all set against the backdrop of the final frontier. Their story is not just fun and engaging, but it also breaks new ground in a franchise known for pushing boundaries.
They’re also so adorable, I can’t help but squeal for a second when they’re in a scene together.

7. Cleveland Booker
Book, whose full name is Cleveland Booker, is a character who brings a refreshing twist to the crew of the Discovery. With his absolutely gorgeous smile charming personality and a heart as vast as the galaxies he explores, Book is a true standout. He’s not your typical Starfleet member – in fact, he’s not one at all! Book is an independent courier with a deep love for all living creatures, which aligns beautifully with his unique ability to communicate with plants and animals. This talent not only adds an intriguing element to his character but also leads to some truly heartwarming and sometimes hilarious moments throughout the series.
But what really makes Book shine is his complex background and the personal growth he undergoes. He starts as a loner, wary of trusting others, but as he journeys with the Discovery crew, we see him open up, forming deep bonds, particularly with Michael Burnham. His evolution from a solitary figure to a key team player, who’s not afraid to show his vulnerabilities, adds depth to his character. Book is a perfect blend of mystery, charisma, and heart, making every scene he’s in captivating and full of potential.
Whether he’s navigating through dangerous space anomalies or having a quiet moment with his beloved cat, Grudge, Book keeps us engaged and rooting for him all the way.

6. Sylvia Tilly
Ah, Tilly, Tilly. My favorite in the series and one of my overall favorite Star Trek characters ever written. Tilly isn’t just a character on Star Trek: Discovery; she’s a journey we all get to experience.
Starting as a cadet, Tilly might have seemed like your typical eager-to-please, slightly awkward newbie, but oh, how she grows! She blossoms into a truly competent officer, showing us that with a bit of grit and a lot of heart, anyone can achieve their dreams. Tilly’s relatability is off the charts.
She’s the friend I personally really wish I had, the one who makes mistakes, learns from them, and always tries again, and is there to support you and not judge you while you make the same path of mistakes. Her journey from a wide-eyed cadet to a confident officer isn’t just inspiring – it’s a tribute to the very essence of Star Trek. It’s about exploration, not just of the galaxies out there, but of the potential within ourselves. Tilly’s character is a beautifully written reminder of this, and it’s no wonder that she’s quickly become one of the best Star Trek characters ever.
Her story isn’t just about space adventures; it’s about growing up, facing challenges, and becoming the best version of yourself. And that’s something we can all aspire to, whether we’re traveling among the stars or navigating our daily lives here on Earth.

5. Philippa Georgiou (Mirror Universe version)
It’s Michelle Yeoh, ’nuff said.
Philippa Georgiou from the Mirror Universe in Star Trek: Discovery is a character who truly turns the tables on expectations. Imagine going from a feared and ruthless emperor, reigning over the Terran Empire with an iron fist, to someone who begins to question and challenge her own beliefs and change. That’s the journey of Georgiou, and it’s nothing short of fascinating.
What makes her so captivating is this drastic shift in her character. Initially, she’s this daunting figure, someone you’d think twice before crossing paths with. But as the series unfolds, we see layers of her personality being peeled back, revealing complexities and even vulnerabilities. It’s like watching a diamond being cut from a rough stone – each episode carves out a new facet of her character, showing us that even the most formidable figures can evolve.
Georgiou’s transformation is a rollercoaster ride of intrigue, power plays, and unexpected emotional depth, making her an unforgettable part of the Star Trek: Discovery universe. The fact that she’s portrayed by Academy Award winner Michelle Yeoh is just a bonus – and Yeoh is brilliant, truly brilliant at what she does.

4. Hugh Culber
Hugh Culber is a character who embodies resilience and emotional depth, particularly after his remarkable resurrection. This event not only adds a fascinating twist to his storyline but also deepens the emotional landscape of the series. Culber, a skilled Starfleet medical officer, is much more than just his professional title. His relationship with Paul Stamets, another key and incredible character, brings a layer of heartfelt intimacy and relatability to the show. Their dynamic is not just a portrayal of a couple in space: it’s a nuanced exploration of love, support, and the challenges they face together in an ever-evolving and often unpredictable universe.

3. Paul Stamets
Meet Paul Stamets, a character who brings a fascinating blend of brilliance and emotional depth to Star Trek: Discovery. As a mycologist and Starfleet science officer, Stamets stands out with his groundbreaking work on the mycelial network, a discovery that revolutionizes space travel in the Star Trek universe. But it’s not just his scientific acumen that makes him a standout. What truly captivates audiences is Paul’s deeply personal journey.
Stamets’ story is not just about exploring the final frontier; it’s about exploring the frontiers of the heart. His loving relationship with Hugh Culber, filled with both tender and challenging moments, adds a rich layer of human depth to his character. Through ups and downs, triumphs and trials, Paul Stamets offers a compelling portrait of a man who navigates the complexities of space, science, and love with equal passion and determination.

2. Saru
Saru, the Kelpien Starfleet officer, is a fascinating character in Star Trek: Discovery who takes us on an incredible journey. When we first meet Saru, he’s a by-the-book officer, always cautious and sticking closely to the rules. This isn’t surprising, considering his background as a Kelpien – a species known for their heightened sense of danger. But as the series unfolds, Saru transforms in the most remarkable ways. He grows from this rule-following, somewhat timid officer into a wise and compassionate captain, showing us that bravery isn’t about the absence of fear, but about facing it head-on.
What’s really exciting about Saru’s character is how he challenges his own beliefs and limitations. He learns to balance his natural instincts with the demands of leading a diverse crew in uncharted territories. His journey is not just about taking command, but also about discovering his own strengths and embracing his identity beyond his species’ characteristics. Saru becomes a symbol of growth and adaptability, proving that true leadership comes from the heart as much as it does from the mind. His story is a blend of personal evolution, courage, and empathy, making him a standout character in the world of Discovery.

1. Michael Burnham
Michael Burnham, portrayed by the incredible Sonequa Martin-Green with compelling depth and nuance, stands at the heart of Star Trek: Discovery. She’s not just a character – she’s a journey, a story of resilience, growth, and discovery (no pun intended) that resonates deeply with fans. What makes Michael so captivating is her layered personality, combining the logic of her Vulcan upbringing with the passionate heart of a human explorer. She’s the kind of person who makes mistakes, learns from them, and becomes stronger, more relatable with each challenge she faces. From her initial status as a mutineer to her inspiring rise as a leader and a key figure in the Starfleet, her evolution is a rollercoaster of emotions, surprises, and triumphs.
