The Yeti appeared twice in the fifth season of the series as adversaries of the Doctor’s second incarnation (Patrick Troughton). They are introduced in the 1967 serial "The Abominable Snowmen" guarding a cave near a Buddhist monastery in the Himalayas, scaring or killing travellers. The Yeti robots are protecting a pyramid of spheres that house the Great Intelligence, who has also possessed the body of the High Lama Padmasamabhava (Wolfe Morris) ever since encountering the man on the astral plane some centuries ago. Using Padmasambhava the Great Intelligence moves small Yeti pieces around a chess-like map of the monastery and mountainside. The Great Intelligence intends to create a physical body for itself, but these plans are foiled by the Doctor and his companions. With the Intelligence banished back to the astral plane the Yeti fall dormant. Several Yeti curiosities are taken back to England by Travers (Jack Watling), who had come in the hopes of encountering the real Yeti.
