Sovak was a Ferengi who assisted archaeologist Dr. Samuel Estragon in his work.
He was cheated by Estragon's assistant Vash after he paid for information about the Tox Uthat. He believed that Jean-Luc Picard conspired with Vash, and confronted Picard and Vash as they were leaving the hotel to look for the Tox Uthat. Picard disarmed him and knocked him out. Sovak later found them in a cave and ordered them to dig for the relic. Picard eventually found the Uthat and destroyed it to keep it out of the Ferengi's hands, and to keep it from the Vorgons.
He was one of the few Ferengi to refer to Humans as "Human" rather than "Hew-mon." (TNG: "Captain's Holiday")
