Star Trek: Discovery Season 3 Returning Cast & New Character Guide

Here's who makes up all of the Star Trek: Discovery season 3 cast and characters. The flagship CBS All-Access Star Trek series executive produced by Alex Kurtzman and Michelle Paradise is boldly going the furthest the franchise has ever gone, with Michael Burnham (Sonequa Martin-Green) and the U.S.S. Discovery warping to the 32nd century.

Star Trek: Discovery season 3 is in uncharted territory and when the Starfleet time travelers land in 3188, they will find an uncertain future where the United Federation of Planets has collapsed because of a cataclysm called The Burn. While the crew of the U.S.S. Discovery makes the jump to the distant future intact, they are also going to meet new allies such as the roguish Cleveland "Book" Booker (David Ajala). In addition, Star Trek: Discovery is making franchise history by introducing its first non-binary and transgender actors, Blu de Barrio as Adira and Ian Alexander as Grey, respectively.
