"Avalanche" is the fifth episode of Captain Scarlet and the Mysterons, a British 1960s Supermarionation television series co-created by Gerry and Sylvia Anderson. Written by Shane Rimmer and directed by Brian Burgess, it was first broadcast on 27 October 1967 on ATV Midlands. In this episode, the Mysterons kill and reconstruct a maintenance engineer to cripple the Frost Line Outer Space Defence System.

The Frost Line Outer Space Defence System is a network of missile complexes stretching 3,000 miles across Northern Canada, tasked with protecting Earth against extraterrestrial threats. After the Mysterons vow to destroy major Frost Line bases, maintenance engineer Eddie is killed when the Mysteron influence engineers the crash of his snowcat, and is reconstructed as an agent in their service. The duplicate of Eddie deceives security at both Red Deer and Cariboo Bases and places devices inside the ventilation systems that render the air unbreathable, killing 250 personnel at Red Deer followed by 70 at Cariboo. General Ward, the belligerent Frost Line commander, warns Spectrum Cloudbase that he will target Mars if other bases are attacked – an action that will undoubtedly trigger a violent response from the Mysterons. A despairing Colonel White (voiced by Donald Gray) orders Captain Scarlet (Francis Matthews) and Lieutenant Green (Cy Grant) to investigate Red Deer; there, the officers discover that the inhabitants have suffocated due not to the introduction of toxic gas into the base's artificial atmosphere, but the removal of all its oxygen.
