Dominar Rygel XVI (called simply Rygel) is a fictional character and one of two regular puppet characters on the television science fiction series Farscape. Rygel is operated by John Eccleston, Sean Masterson, Tim Mieville, Matt McCoy, Mario Halouvas and Fiona Gentle. His voice is provided by Jonathan Hardy.
Rygel was ruler of the Hynerians, an empire encompassing more than 600 billion loyal subjects until he was deposed by his cousin Bishan. When we first meet Rygel he had been in Peacekeeper custody for more than 300 cycles, and it was Rygel's initial escape that led to the revolt that allowed the prisoner crew to take control of Moya.
Rygel is extremely self-centered, and virtually all of his actions are out of self-interest (although toward the end of the series we see him get emotional, towards Moya, for one). His cleverness and bargaining abilities (as well as his small size) have come to the aid of Moya's crew on multiple occations.
Crichton refers to Rygel often as "Sparky" and "Buckwheat."
