Great Intelligence

The Great Intelligence (or Yog-Sothoth) has no physical form. As a disembodied sentience, it seeks bodies and physical existence and has used the Robot Yeti to accomplish this.

History
as one of the Old Ones, beings who existed before the universe. Yog-Sothoth existed before the present universe (MA: Millenial Rites). In the present universe, the Tibetan lama Padmasambhava on the astral plane. The Great Intelligence possessed Padmasambhava. In 1935, The Doctor, a friend of the lama's, as well as Travers, a westerner determined to find the Yeti, intervened. Padmasambhava's physical body died. (DW: The Abominable Snowmen) Thirty-five years or so later, the robot Yeti re-activated and the Intelligence manifested as webbing, ensnaring the Doctor's TARDIS in space and forcing it to land.
