Waldo Pickering was a former United States Senator from one of the southern states. He was involved with Brigham Elisha Dashwood III and the state of Malebolgia.
Pickering was the former senator of the state from which Malebologia seceded from and was Dashwood's primary rival for the position of governor of Malebologia. When Dashwood publicly announced his candidacy, Pickering attended the event as an observer, opponent and minor trouble-maker.
Seeing an opportunity to rid himself of a rival, Dashwood helped the demon Marchosias possess Pickering in 2003. 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.
Waldo Pickering's granddaughter Becky Lee Kowalczyck lived with him from time to time. She used his home as a local base in her fight against supernatural evil as a member of the Order of Saint Peter. (AUDIO: Minuet in Hell)
