K9 (The Choice)
From Tardis Wiki, the free Doctor Who reference
A version of K9 travelled with the Mistress in Ecto-Space. It was unclear how he was related to other K9 models in the normal universe. (AUDIO: The Choice, The Search)
Behind the scenes
This version of K9 — divorced from any explicit ties to a televised version — was created to give BBV Productions clear access to those elements of K9 wholly owned by Dave Martin and Bob Baker.
