Fat One

The Fat One, along with his husband, the Thin One, were part of the Anglican Regiment of the Church stationed at Demons Run. The two seemed to have no names, instead using "the Fat One" and "the Thin One" to refer to each other. When Lorna Bucket asked them if they had names, they said that they were the "Thin/Fat Gay-Married Anglican Marines" and asked why would they need names. It seems that 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.
