Thaddeus Kanner

Thaddeus Kanner was an expert mountaineer who often explored for mystical beings. He went up Ben MacDui with the Seventh Doctor, Alistair Gordon Lethbridge-Stewart and Niamh Godec and did not like taking advice. He wanted to hunt the Grey Man. After looking at the Grey Man's face he started acting paranoid. (AUDIO: The Grey Man of the Mountain)
