Shada is a story from the British science fiction television series Doctor Who. Written by the series' script editor Douglas Adams, it was intended as the final serial of the 1979–80 season but was never originally completed, owing to strike action at the BBC during studio recording. Entering production as a six-part story in 1979, plans were later revised for the story to be broadcast as a four-part story in 1980. Ultimately however, the story was never completed in either format.

K9, occasionally written K-9, is the name of several fictional robotic canines in the long-running British science fiction television series Doctor Who, first appearing in 1977. K9 has also been a central character in three of the series' television spin-offs: the one-off K-9 and Company (1981), The Sarah Jane Adventures (2007–2011) and K9 (2009–2010). Although not originally intended to be a recurring character in the series, K9 was kept in the show following his first appearance because he was expected to be popular with younger audiences. There have been at least four separate K9 units in the series, with the first two being companions of the Fourth Doctor. Voice actor John Leeson has provided the character's voice in most of his appearances, except during season 17 of Doctor Who, in which David Brierley temporarily did so. The character was created by Bob Baker and Dave Martin, to whom rights to the character still belong; consequently, Baker's spin-off series K9, which is not BBC-produced, could not directly reference events or characters from Doctor Who, though it attempted to be a part of that continuity.
