Sarah Jane Smith is a fictional character played by Elisabeth Sladen in the long-running BBC Television science fiction series Doctor Who and two of its spin-offs. Sarah Jane is a dogged investigative journalist who first encounters alien time traveller the Doctor while trying to break a story on a top secret research facility, and subsequently becomes his travelling companion on a series of adventures spanning the breadth of space and time. After travelling with The Doctor in four seasons of the show they suddenly part ways, and after this she continues to investigate strange goings-on back on Earth. Over time, Sarah Jane establishes herself as a committed defender of Earth from alien invasions and other threats, occasionally reuniting with The Doctor in the course of her own adventures, all the while continuing to work as a freelance investigative journalist.
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.

They were convicted on their home world, not willing to return to their planet in fear of receiving a death sentence.
