Best of Enemies is the fifth episode of Series 2 of Gerry Anderson's New Captain Scarlet.


Spectrum is assisting with sea trials of a new stealth warship, Proteus. After the vessels computer-controlled camouflage system thwarts an attack run by the Angels, Colonel White, Captain Scarlet and Lieutenant Green remain on board to look around. While the Captain shows White and Scarlet the ships complement of powerful Crusader X50 missiles, First Officer Eden gives Lieutenant Green a tour of the ships computer room; however, when Eden attempts to use a control console he is electrocuted by a blast of Mysteron energy, and, as Green looks on, the Mysterons take over the mainframe and seize control of Proteus. Having jammed all communications systems, the Mysterons use their influence to turn the vessels maintenance robots into mechanised killers, injuring White with a laser blast. Meanwhile, the ships navigator, Mr Viegler, panics and makes off in the Spectrum agents Hummingbird Helicopter; but as he lifts off, the helicopter is shot down by the ships anti-aircraft guns. Realising that they are trapped aboard Proteus with no way of warning Spectrum, Scarlet instructs Green to look after the Colonel, while he tries to find a way to stop the rogue vessel.
