The theme is most prevalent in Revenge of the Sith. It is played when Yoda, Mace Windu, and Obi-Wan Kenobi discuss Palpatine's intentions prior to Yoda leaving for Kashyyyk; after Sidious bestows upon Anakin the title of Darth Vader, and when the Emperor rescues Vader from Mustafar.
One of the musical pieces in Super Star Wars: Return of the Jedi, played during several stages, incorporates an up-tempo variation of the Emperor's theme as its bridge. The normal version of the theme is included as well and is played on the 'Game Over' screen.
In Star Wars: X-Wing vs. TIE Fighter, part of "The Emperor's Theme" is played after a mission failure.

A segment of "The Emperor's Theme" is played whenever the player has gained a dark side point in the latter game. "The Emperor's Theme" plays during the mission briefing screens in Star Wars: Republic Commando.
The theme is played in Star Wars: The Clone Wars Season 5 Episode 16 "The Lawless", when Palpatine tells Mas Amedda to prepare his ship, and again when he confronts Darth Maul and Savage Opress on Mandalore. It is also played in the Season 6 Episode 4 "Orders", when Count Dooku speaks with Palpatine about Order 66.
