Captain Scarlet and the Mysterons

Mankind comes under threat from the Mysterons in this marionette-based series (32 episodes: 29/09/1967 to 14/05/1968). Captain Scarlet, whose real name is Paul Metcalfe, is one of the few humans able to resist their charms. An agent of Earth defence service Spectrum, he was once killed by the Mysterons before being replaced by a duplicate under their control. But the duplicate fell several hundred feet from a tower, and the shock allowed Metcalfe's true personality to reassert itself. His new body had the power to sense nearby Mysterons, and also to re-create itself with "retro-metabolism" should he ever be injured or killed. No-one ever explained why this happened to him, but it didn't matter because it was a thrilling series for children and adults alike!
