In 1986, he replaced Jim Henshaw as Wicket Wystri Warrick for the second season of the Ewoks TV series.
He also returned to Star Wars with Star Wars: Dark Forces, though not in the main roles: He voiced nameless characters (a stormtrooper, a dying Rebel later identified as Admiral Toka) and the narrator.
Delk voiced a Red Shirt in Star Wars: Rebel Assault II: The Hidden Empire. However, Star Wars: TIE Fighter allowed Delk to become the villain, Grand Admiral Zaarin, as well as a major supporting character, the Priest.
During 1997, Delk voiced Mutant Kowakian monkey-lizard Pic and 8t88 in Star Wars: Jedi Knight: Dark Forces II.
In 1998 Delk voiced Red Leader, Intercom Voice and Trench Officer in Star Wars Trilogy Arcade.
Delk would not return to Star Wars until 1999, where he would reprise Zaarin in Star Wars: X-Wing Alliance. He showed his versatility by playing different Rebel characters, including a pilot, an officer and a Bothan.
In 2000 he voiced a Slingshot Announcer in Star Wars: Early Learning Activity Center.
Delk worked as the narrator for the Rogue Squadron series (as well as a commander and a wingman in its final installment). He also narrated Star Wars: Empire at War and Star Wars: Empire at War: Forces of Corruption (2006) and voiced the training officer in Battlefront II (2005).
