The Sorvix were carnivorous Sorvans (AUDIO: Superiority Complex) that had huge mouths on their backs (AUDIO: Aliens & Sex & Chips & Gravy)
They fled Sorva to live on Earth. One Sorvix, Ro-Jedda, was the leader. She stuck a collar on Orr so that it would explode. However, Torchwood Three came and released it. (AUDIO: Orr) The Sorvix built Cardiff Bay Intelligent Hotel and Spa to give the Sorvix and other allied alien races a place to stay without the necessity of being bothered by humans. However, the Hotel went rogue and started to kill the rest of the guests. It was unknown if Ro-Jedda had anything to do with its malfunction. Afterwards, she tricked the Lord Mayor of Cardiff into a sealed room and "[took] a long sick day" (AUDIO: Superiority Complex)
The Sorvix fled Earth after the arrival of their God. Ro-Jedda was imprisoned and later shot by Yvonne Hartman. (AUDIO: Future Pain) Their presence on Earth was covered up by Tyler Steele, who manipulated the conspiracy theorist Brent Hayden. (AUDIO: The Man Who Destroyed Torchwood)
