Seek and Destroy (Captain Scarlet and the Mysterons)

"Seek and Destroy" is the ninth episode of Captain Scarlet and the Mysterons, a 1960s British Supermarionation television series created by Gerry and Sylvia Anderson and produced by their company Century 21 Productions. The ninth episode of the series to be produced, it was written by Peter Curran and David Williams and first broadcast on 5 January 1968 on ATV Midlands.

Set in 2068, the series depicts a "war of nerves" between Earth and the Mysterons: a race of Martians with the power to create functioning copies of destroyed people or objects and use them to carry out acts of aggression against humanity. Earth is defended by a military organisation called Spectrum, whose top agent, Captain Scarlet, was killed by the Mysterons and replaced by a reconstruction that subsequently broke free of their control. Scarlet's double has a self-healing power that enables him to recover from injuries that would be fatal to anyone else, making him Spectrum's best asset in its fight against the Mysterons.

In "Seek and Destroy", a Mysteron threat to kill one of the Spectrum Angel pilots leads to the squadron doing battle with a trio of reconstructed Angel fighters. "Seek and Destroy" has been praised for its aerial shots and other special effects sequences. It is one of four Captain Scarlet episodes that were later re-edited and combined to create Captain Scarlet vs. the Mysterons (1980), a made-for-TV Captain Scarlet compilation film produced by the New York office of distributor ITC Entertainment.
