"The Fat One", along with his husband, "the Thin One", were part of the Anglican Regiment of the Church stationed at Demons Run. They both discussed the rumours of the Doctor's actions, and even though they feared him, and their job was to kill him, they couldn't help liking and praising him. When Lorna Bucket asked them if they had names, they said that they were the "Thin/Fat Gay Married Anglican Marines" and jokingly asked why would they need names. In accordance with the Headless Monks alliance protocol, he was to be initiated into their religion as part of Kovarian's bargain with them for help keeping Amy and Melody Pond captive for the trap set for the Doctor. Understandably, the Fat One's beheading deeply upset his husband. (DW: A Good Man Goes to War)
