Gideon is a human former officer of the Imperial Security Bureau who, five years after Endor, commands a remnant force in the Outer Rim. He is played by Giancarlo Esposito in The Mandalorian, first appearing in the 2019 first season.
He is the clearest statement the New Republic era has made about what "the Empire fell" actually means: the institution collapsed, the people did not, and some of them kept working. Gideon's interest in the child Grogu — and the cloning programme behind it — is the through-line of the series' first three seasons.
