The Doctors robotic sidekick from the 70s is about to launch his own TV show. Park Entertainment have announced that the series has reached post production and should hit TV screens in Australia and Europe early next year. K9 first appeared in Doctor Who in 1977 as the companion of the fourth Doctor, played by Tom Baker. There have been four different versions of K9 already, K9 Mark I left the show when he accompanied Leela to Gallifrey. K9 Mark II then left with another companion, Romana. K9 Mark III was introduced for the first K9 spin-off TV show entitled K9 and Company, which featured Elisabeth Sladen reprising her role as Sarah Jane Smith. That series was axed and nothing was seen of K9 until a brief cameo in the special Doctor Who episode The Five Doctors in 1983. K9 then returned to the show, along with Sladen in the episode School Reunion featuring David Tennant as the tenth Doctor. K9 Mark III was destroyed in that episode and the Doctor rebuilt him as K9 Mark IV, Mark IV has since featured in another Doctor Who spin-off, The Sarah Jane Adventures. This latest K9 series will not feature any other characters from the Doctor Who universe and is clearly aimed at a younger audience than Doctor Who. Park Entertainment describe it as X Files meets Men in Black with a zany dash of Ghostbusters.
