Waldo Pickering

 was a former United States Senator from one of the southern states who was involved with Brigham Elisha Dashwood III and the potential creation of the State of Malebolgia. (BFA: Minuet in Hell)

History
Pickering apparently had lost his Senate seat to Dashwood, so he viewed Dashwood as his arch-enemy. When Dashwood was elected Governor of the proposed State of Malebolgia, Pickering attended the event as an observer, opponent and minor trouble-maker.

Dashwood, seeing an opportunity to rid himself of a rival, helped the demon Marchosias to possess Pickering. The possessed Pickering publicly dropped all opposition to Dashwood's endeavours, including Dashwood's mental institution and the newly reformed Hellfire Club.

The intervention of the Eighth Doctor, Charlotte Pollard, and Brigadier Alistair Gordon Lethbridge-Stewart soon revealed Pickering's possession and drove Marchosias out. (BFA: Minuet in Hell)
