John Angus Mackay

John Angus Mackay was Professor Edward Travers' companion on his expedition to the Himalayas in 1935. He was the first and best friend of Travers, and his only friend to agree to accompany him on the expedition. (PROSE: Doctor Who and the Abominable Snowmen) He was killed by a robot yeti when they were sleeping in their camp. Travers caught a glimpse of the furry creature, which led him to believe the Second Doctor (wearing his giant shaggy coat) murdered John. (TV: The Abominable Snowmen)

In an alternate version of Earth, John survived the expedition in the Himalayas and Travers did not. (PROSE: The Schizoid Earth)
