Classic mid 1960's Supermarination television series. The story follows Captain Scarlet and international agency 'Spectrum' in their fight against the Martians-The Mysterons. The Mysterons whose home planet is Mars were originally attacked by a Spectrum squad who were doing routine patrols whilst on Mars. The unprovoked attack by Spectrum launched an all out war in wich The Mysterons swore they would revenge.
Captain Scarlet is not so much 'invincible' as he actually regenerates. He can die, yet comes back to life shortly afterwards.
