Firmus Piett, a human male native to Axxila, was an Imperial officer who served in the naval forces of the Galactic Empire during the Galactic Civil War. At the time of the Battle of Hoth, he served as first officer of the Star Dreadnought Executor—flagship of the Sith Lord Darth Vader—assisting Admiral Kendal Ozzel. After Ozzel committed a fatal mistake during the hunt for the Rebel Alliance, Piett was promoted to admiral and given command of Vader’s flagship. Piett served in that capacity until the Battle of Endor, where he served as a Fleet Admiral, when the Imperial Navy confronted the Rebel Fleet around the second Death Star battle station in the year 4 ABY. The admiral perished aboard his starship when Arvel Crynyd‘s A-wing starfighter crashed into the Executor‘s bridge.

Admiral Piett was played by Kenneth Colley in both 1980‘s Star Wars: Episode V The Empire Strikes Back and 1983‘s Star Wars: Episode VI Return of the Jedi. Piett is the only Imperial officer to survive more than one film and be portrayed by the same actor. As a result, Piett became a favorite character among fans due his unusual longevity over time. Though not originally intended to return in Return of the Jedi, fan mail supporting the return of the character convinced George Lucas to rehire Colley once more and write several new lines of dialogue for him.
