K-9 was originally created by writers Bob Baker and Dave Martin for the Fourth Doctor Tom Baker. First appearing in the The Invisible Enemy (1977) episodes Professor Marius allows his K-9 robot to travel with the Doctor. Naturally K-9's first words on screen are "Affirmative Master!" 'Mark I' K-9 was designed by Tony Harding and built by the BBC Visual Effects Department. Mark II K-9 appeared in The Invasion of Time (1978) with Tom Baker and the Sontarans.
K-9 recently appeared in School Reunion (2006), subsequently guesting in the spin-off show The Sarah Jane Adventures. In School Reunion Mark III K-9 has a worn 'rusty' appearance, but at the end of the episode the Doctor gifts a shiny new rebuilt Mark IV version to Sarah Jane Smith.
Over the years, many K-9 toys have been made by, amongst others, Palitoy, Corgi, Dapol, Marks & Spencer, Product Enterprise and Character Options.

K-9's creator Bob Baker is currently working with Paul Tams, Park Entertainment and Disney's Jetix Europe on the new TV series featuring K-9. Paul Tams was a designer and illustrator on the Classic Doctor Who series.
K-9 Adventures will have 26 half hour episodes featuring a mix of live action and CGI. For the new series K-9 is being redesigned and will reportedly have a new 'thinking metal' structure allowing him to morph into different guises. He also has defence, rescue and aqua collars.
On board the spacecraft 'Platte', 'Slocum' a commodity trader and space gypsy and 'Djinn' a V997(F) android discover an abandoned battle cruiser containing...K-9.
