Emperor Staleek is the Scarran emperor, played by Duncan Young and is a major antagonist in both the series and the mini-series. He first appears in the "We're So Screwed" three-part story in season 4, holding a conference at the secret moon of Katratzi. It was there he first encounters John Crichton. Crichton comes to Katratzi under the guise of selling the information he has on wormhole technology to the highest bidder. Crichton is truly there to rescue Scorpius, whom Staleek has prisoner at the base. During that time, Staleek hopes to find a way to capture Crichton without setting off the nuclear bomb attached to Crichton's belt. He is also under the impression that Scorpius is his spy and double agent, but in truth, Scorpius turns out to be a triple agent whose true allegiance is to the Peacekeepers. When Crichton severely damages the Katratzi base, Staleek orders Captain Pennoch to Earth, as he has learned from Crichton that the planet contains a large supply of the crystherium flower, vital to the Scarrans' power. Pennoch's mission fails and his ship is destroyed by Crichton and Aeryn Sun.
