In the Series 7 finale, "The Name of the Doctor", the Great Intelligence manifests through and manipulates dark creatures called the Whisper Men, changing the one it inhabits into the form of Dr Simeon.
The Great Intelligence and its Yeti servants are featured in the 1995 spin-off video film Downtime, produced by Reeltime and featuring Victoria Waterfield (Deborah Watling), the Brigadier (Nicholas Courtney) and Sarah Jane Smith (Elisabeth Sladen) with a now deceased Professor Travers (Jack Watling) serving as a vessel for the Intelligence.
