Main Characters

The show's ensemble cast revolves around four ensigns who are navigating their first assignments on the U.S.S. Cerritos.

Their camaraderie, rivalries, and individual growth journeys are at the heart of "Lower Decks," providing ample opportunity for humor, drama, and a healthy dose of the absurd – all set against the backdrop of the lives of the lower deck crew.

Ensign Beckett Mariner

Voiced by comic legend Tawny Newsome, Ensign Mariner is a skilled and charismatic Starfleet officer with a penchant for breaking rules. Her rebellious streak and impulsive behavior often put her at odds with her superiors, but her quick thinking and determination have a way of turning situations around.

Despite her hardened exterior, Mariner harbors a complex relationship with her mother, who also serves on the Cerritos, adding an extra layer of family dynamics to the show.

Ensign Brad Boimler

The neurotic and meticulous Boimler, voiced by Jack Quaid, is Mariner's polar opposite and constant foil. A dedicated Starfleet officer who takes his duties very seriously, Boimler's obsessive-compulsive tendencies and anxiety often lead to hilarious situations on the ship.

As he navigates his friendship with Mariner and his own insecurities, Boimler's character arcs serve as a compelling exploration of the sometimes-overwhelming expectations placed upon Starfleet officers.

Supporting Characters

The realm of "Lower Decks" is filled with memorable supporting characters who enrich the narrative and provide a wealth of material for the show's humor and storytelling.

From the enigmatic and occasionally menacing alien crew members to the diverse humans who call the U.S.S. Cerritos home, these characters help to create a vibrant and engaging world for the main cast to interact with.

Lieutenant Commander T'mar

Voiced by the talented Noël Wells, the Vulcan-Andorian hybrid, T'mar, is the U.S.S. Cerritos' first officer and a formidable adversary for Mariner and Boimler. Her logical and Stoic demeanor often clashes with the ensigns' more emotional approaches to problem-solving, leading to a host of entertaining conflicts and growth opportunities.

T'mar's unique heritage and Vulcan upbringing provide a rich foundation for exploring themes of cultural identity, logic vs. emotion, and the complexities of leadership within the Star Trek universe.

Doctor T'Ana

The idiosyncratic ship's doctor, T'Ana, voiced by the versatile Dawn Lewis, is an inclination-having, non-corporeal being who lives in the ship's computer systems. Her quirky personality and penchant for puns make her a fan favorite, as she dispenses medical advice and provides comic relief throughout the series.

As the only physician onboard the U.S.S. Cerritos, T'Ana's keen medical insight and unconventional methods often prove essential in saving the lives of her crewmates, even as she grapples with her own issues of self-awareness and existential angst.

As "Star Trek: Lower Decks" continues to unfold, it is clear that the rich tapestry of characters and their evolving relationships will continue to captivate and engage audiences. With its blend of humor, heart, and classic Star Trek themes, the show offers a unique and refreshing perspective on the beloved franchise, leaving fans eager for more adventures aboard the U.S.S. Cerritos.
