Steven Taylor (Peter Purves)
Steven Taylor was a prisoner of the evil robot Mechanoids when the Doctor met him, on the planet Mechanus. A space ship pilot, Steven was grateful to be rescued by the Doctor, who was travelling with Vicki, Ian and Barbara at the time.
Stalwart and courageous, Steven twice encountered the Monk, once during a lengthy battle against the Daleks. Following Vicki's departure, the travellers were joined by Dodo, and had several contrasting adventures; with the Celestial Toymaker, in the Wild West, and, ultimately, on the planet of the Savages, where Steven left to mediate between two factions, as their elected leader.
