Star Trek: Discoverys 4 Number Ones Explained

Just as Star Trek: Discovery has featured several different Captains of the USS Discovery throughout its five-season run, the show has also introduced four different Number Ones. Since its beginning, Discovery has been less of an ensemble show than previous Star Trek series, and the crew of the USS Discovery has been constantly shifting. Discovery

tells the story of Michael Burnham (Sonequa Martin-Green), who has gone from being an accomplished First Officer to a notorious criminal to the Captain of Discovery. Burnham has filled the position of Number One more than once, and two of her best friends have also taken on that role.
