Star Trek: Discovery - Kenneth Mitchell's Roles, Explained

As a fan who has followed Kenneth Mitchell’s remarkable journey through his roles in Star Trek: Discovery, I can’t help but feel a profound sense of admiration and respect for this extraordinary actor. His career was tragically cut short by ALS, but his legacy will live on forever.


Kenneth Mitchell’s career was unfortunately ended prematurely, yet he personified the notion that “every role is significant; it’s only the performer who makes it small.” In February, admirers of Star Trek: Discovery were taken aback when the Canadian actor died at 49, following a valiant fight against Amyotrophic Lateral Sclerosis (ALS).

In more than 50 films and television productions, including a significant role in the 2019 film “Captain Marvel” as the superhero’s father, Mitchell has made an impression. However, it is his portrayal of various characters throughout three seasons of “Star Trek: Discovery” that will likely resonate most with fans. Beyond this, Mitchell paved the way for actors with disabilities, and he leaves behind a lasting legacy by opening new paths for disabled representation in media.

Who Did Kenneth Mitchell Play in Star Trek: Discovery?

Kenneth Mitchell embarked on his Star Trek: Discovery journey back in 2017 when the series premiered, and he continued until the conclusion of its third season in 2021. Throughout this time, he played a variety of significant characters.

  • Kol: Mitchell made his debut as Kol, the Klingon warrior from the House of Kor, whom he played in five episodes of Star Trek: Discovery, season 1. The actor had an unlikely start, as he had no idea he was auditioning to be a Klingon. But the role turned out to be a near-perfect fit, as he pulled off the demeanor of the villainous Klingon starship commander. Mitchell embraced the challenge head-on, as he went above and beyond to learn Klingon speech. Thanks to his dedication, he delivered a powerful, memorable performance as Kol.
  • Kol-Sha: After Kol’s death in the first season, Mitchell expressed his wish to return to the show as a Changeling. However, he got his opportunity through a different Klingon role — this time as Kol-Sha, Kol’s father. Once again, the actor brought his menacing appearance to the show as the head of the House of Kor in season 2, episode 3.
  • Tenavik: Kenneth Mitchell’s connection with the Klingon world went even further when he portrayed Tenavik, the Time Keeper, in Star Trek: Discovery, season 2, episode 12, as well as an uncredited appearance in episode 14. Interestingly, Tenavik happens to be the same child kidnapped by Mitchell’s other character, Kol-Sha, in season 2, episode 3, “Point of Light.” Tenavik is the son of Voq and L’rell, and Mitchell’s performance conveys the complex emotions of coming face-to-face with his complicated familial history. Despite being just a few months old, Tenavik lives as a fully grown adult in a monastery with Klingon monks guarding the sacred time crystals.
  • Aurellio: In the final and possibly most significant role of his career, Mitchell played the scientist Aurellio, a role specifically created for the actor after his ALS diagnosis and the resulting progression of his illness. The actor shed his heavy Klingon makeup to play a human scientist employed by the Emerald Chain in two episodes of season 3. The character moves around in a hover-chair due to paralysis from a genetic condition, which mirrors Mitchell’s own use of a wheelchair at the time due to his loss of mobility as a result of ALS. Aurellio works for the antagonist Osyraa, but after building a rapport with fellow scientist Paul Stamets, he ends up helping the Discovery crew.

Kenneth Mitchell lent his voice to three characters in the 2020 animated series “Star Trek: Lower Decks“. In episode 8 of season 1, titled “Veritas”, he portrayed Black Ops Officer 2, Romulan Guard 1, and Tweerk Captain. However, his hope to reprise his role in season 4 of “Star Trek: Discovery” in 2021 remained unfulfilled. As his health deteriorated, he could no longer speak without aid. Yet, Mitchell continued to engage with the “Star Trek” community to increase awareness about ALS and offer support to others battling the disease.

Kenneth Mitchell’s Impact on Disabled Actors & Characters

Kenneth Mitchell left a powerful mark in the initial season of Star Trek: Discovery, kick-starting what seemed to be an impressive series of recurring parts for him. Tragically, his ALS diagnosis came at the most inopportune moment, immediately following season 1. Despite this setback, the actor persevered through the second season and kept his condition private until 2020. As time went on, Mitchell needed a wheelchair due to his condition, which affected his acting abilities and the roles he could pursue. In a tough and often indifferent industry, actors with disabilities are frequently overlooked.

However, it’s often the most difficult situations that bring a team together, and this was certainly the case off-screen for the crew of Star Trek: Discovery. The revelation of Mitchell’s health condition transformed them into a close-knit unit. In response, the writers ingeniously introduced the character Aurellio, enabling Mitchell to continue contributing despite his physical restrictions. The team joined forces with him to create a specially designed hoverchair for this character, which also provided the actor with mobility and freedom on set. Mitchell expressed in an interview with trekmovie.com that this role represented Star Trek’s enduring commitment to inclusivity, being part of its long-standing tradition.

As a passionate gamer, I’ve noticed a scarcity of disabled characters in the Star Trek universe, understandably so for various reasons. Yet, when given the opportunity to portray Aurellio, I felt an immense sense of pride. I believe his character was made all the more impactful because while he dealt with disabilities, the narrative emphasized his abilities instead. Each day, as I delved deeper into this role, I reminded myself that despite the numerous physical obstacles I face in real life, my worth and strength remain undiminished.

The team behind Star Trek: Discovery didn’t merely honor Mitchell and his tale of resilience; they made a significant stride in promoting more accurate representation of disabled actors on screen. Historically, characters with disabilities have appeared in films and TV shows, but what sets Kenneth Mitchell’s story apart is the creation of roles and traits that closely mirror the real-life disabilities of the actors portraying them, thereby enhancing the authenticity of the storytelling.
