Nute Gunray is a major antagonist in both the Star Warsprequel trilogy and The Clone Wars.
He is the Viceroy of the Trade Federation and later became a high-ranking officer of the Confederacy of Independent Systems as the head of the Separatist Council. He was one of Darth Sidious' first, and most important, pawns in his plan to attain ultimate power. Following the deaths of both Count Dooku and later General Grievous, Gunray became the de jure leader of the CIS. However, he was ultimately killed by Darth Vader along with the other members of the Separatist Council on Mustafar at the end of Revenge of the Sith.
He was portrayed by Silas Carson (who also portrayed Ki-Adi-Mundi in the prequel trilogy and also voiced The Ood in Doctor Who) in the prequel trilogy, and was voiced by Tom Kenny in Star Wars: The Clone Wars.
