Sorvix

The Sorvix are a carnivorous species that have 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. Ro-Jedda also constructed the Cardiff Bay Intuitive Hotel to give the Sorvix a place to stay. 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)
