Nicholas Blake

Corporal Nicholas Blake (PROSE: Legacies) was an officer in the British Army. He took part in the fight against the Great Intelligence and its robot Yeti in the London Underground. In an attempt to get to the Second Doctor's TARDIS, Blake and Colonel Lethbridge-Stewart were the last survivors of the group of soldiers they had brought. Blake and the Colonel hid in a warehouse when Blake was dragged away and beaten to death by a Yeti. (TV: The Web of Fear)

In an alternative timeline, Blake survived the incursion in London, and was serving under Colonel Pemberton when he was killed in Croydon. (PROSE: Legacies)
