Warning: SPOILERS for Star Trek: Lower Decks Season 5

Lieutenant Bradward Boimler (Jack Quaid) growing facial hair inStar Trek: Lower Decksseason 5 is hilarious, and it’s a running joke that parodies how Captain Benjamin Sisko (Avery Brooks) gradually changed his appearance onStar Trek: Deep Space Nine. InStar Trek: Lower Decks' final season on Paramount+, the USS Cerritos investigates dimensional rifts that lead toalternateStar Trektimelines. Meeting his confident, bearded doppelgangerinspired Boimler to grow a beard of his own.

WhenStar Trek: Deep Space Nineintroduced Commander Benjamin Sisko, he had a full head of hair and was clean-shaven.Avery Brooks' most famous prior role was the bald, goateed Hawk inSpenser for HireandA Man Called Hawk. Paramount Studios didn’t want their 24th centuryStar Trekleading man to resemble a modern-day character so Brooks was given a mandate to adjust his look. Yet Avery was uncomfortable with his appearance. Although it took 3 years,Brooks was able to change Captain Sisko to be bald and sport a goatee.
