K9 Mark 2


 * Not to be confused with K9 Mark II, a version created by the Doctor who considered Romana his mistress.

K9 Mark 2 was an incarnation of K9 created after the Mark I self-destructed. This K9 was associated with Professor Alistair Gryffen. It gave dog whistles to at least Starkey, whom he called "Young Master", and Jorjie, indicating his level of trust in both teenagers.

Biography
After Mark I tracked two Jixen warriors to 2050 London and self-destructed, Starkey retrieved K9's regeneration circuit, allowing him to rebuild completely. This new K9 didn't have any memory of his past life, though he contained a sound file of the Doctor Who theme. It is unknown whether he remembers Gallifrey, The Time War, Romana or Leela. K9 was owned by Alistair Gryffen, who studied this "Fallen Angel", though K9 could come and go as he pleased. Gryffen didn't tell his employers, The Department of this, but they saw him on CCTV. June Turner came to interrogate Gryffen, whilst K9 hid with Darius Pike, Gryffen's assistant. Soon, Starkey arrived, who had been sprayed by a Jixen. K9 confused him for a Jixen and was about to kill him, when he recited the patronising words he gave K9 after his creation and the dog realised that he was Human. K9 gave Starkey his dog whistle, meaning he would assist Starkey if he was ever in trouble and stand at Gryffen's house, ready for more adventures. (K9TV: Regeneration)

Personality
This version of K9 was more upbeat and aggressive than other versions that existed in the universe. Whereas the K9s that traveled with the Doctor tended to apply logic in a somewhat cautious way —frequently arguing why the odds suggested that something couldn't be done —this K9 tended to freely place himself in harm's way.

Unlike other Robots,He was also capable of flatulence.(K9TV: The Korven)

He also investigated Human emotions in a more thorough way than his predecessors, and even, apparently, experienced the emotion of fear. (K9TV: Fear Itself)

His use of the English language was far more colloquial than any of his predecessors, because he had downloaded 5000 Human movies onto his memdrive, and these were influencing his speech. (K9TV: Alien Avatar)

Behind the scenes

 * Although this was a "new" version of K9, it was a new incarnation of K9 Mark I, as opposed to it being a Mark V. This point was made clear in the episode K9TV: The Bounty Hunter.
