Sorvix

The Sorvix were a carnivorous species 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. 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)
