History
The Octopus Rock was built for deep-sea investigation. In 2009, an unidentified sound was heard from the Mariana Trench. Torchwood Three and Carlie Roberts convinced UNIT to allow them to investigate in the Octopus Rock. Once there, they were attacked by Sam Doyle, who was infected with an alien parasite, giving him increased strength. The Octopus Rock was badly damaged and crashed. The team escaped in Guernica, the submarine Sam Doyle had travelled in. (BBCR: Submission)
