Robot Yetis

The Robot Yetis were servitors created by the Great Intelligence, originally as protectors before the Great Intelligence was banished. They first appear in the Season 12 finale where they are used against the Cybermen.

The Yetis that appear in Season 12-13 have better-defined than the ones later seen at the end of Season 20. These hands are capable of wielding weapons. They are quite impervious to bombs and Cyber weapons.

In Season 20, the Yetis are more bear-like, but they have large flaps on their chests covering the control spheres they have in their chests. Without these spheres, the yetis stand motionless, allowing them to be destroyed more easily.
