Features
"Oi! Listen, in the year 5000, this was cutting edge!"

- The Tenth Doctor

The mechanics of K-9 Mark I included rotating ear-probes, telescopic 'eye' probe, extendable nose, flashing lights on the top and the 'eye' panel, waggling tail antennae, and ticker-tape tongue. The head could also move up and down. The shell was painted in gold/grey metallic. Around K9's neck was a tartan collar, from which hung a silver disk. (DW: The Invisible Enemy)

After K-9 Mark I was left behind with Leela on Gallifrey, The Doctor built a improved K-9 Mark II. While the cosmetic changes were minimal (including the new metallic charcoal paint-work), in terms of series continuity K9's character underwent a vast change. Gone was the product of 5000 AD technology, as was the case with Marius's version. This new K9 was a product of the Doctor's own technology and values. The gun was now only capable of stunning - not killing - and K9 now responded to a dog-whistle. K9 also featured a vast memory-bank, seemingly a mixture of the Mark One model, the Doctor's own memory and knowledge, and that of the TARDIS. (DW: The Invasion of Time)

"Why does he look so... disco?"

- Rose Tyler on K-9 Mark III

When the Doctor left Sarah Jane Smith on Earth, he created K-9 Mark III to be Sarah's new companion. The new mechanics of K-9 Mark III included larger wheels in conjunction with a front and back-wheel drive. (K-9 was given a brand new coat of paint (this time a metallic-blue) plus a handle on the top of the shell to make carrying him easier. (KAC: A Girl's Best Friend)

When the Doctor created K-9 Mark IV to replace K-9 Mark III, he added a shiny metallic blue paint job and a number of improvements over Mark IV including an omniflexible hyperlink facility. (DW: School Reunion) Later, though, K-9 reverted to his old, dark green color. (SJA: Invasion of the Bane) In episode 2 of The Lost Boy Sarah Jane unleashes K-9 Mark IV to battle Mr Smith. Before and after the battle K-9 displays a teleport facility and utilises a laser weapon similar to the previous K-9s'. (SJA: The Lost Boy)

Personality
"The small female is hostile."

- K-9 on Kelsey Harper

K-9 had a very consistent personality from model to model. He had a polite, formal manner with just a hint of pedantry bordering on condescension. Though he often displayed feelings such as sorrow (DW: The Invasion of Time) and self-regard (DW: School Reunion), he often stated that he had not been programmed to have emotions (SJA:Invasion of the Bane.

He did not use contractions just as "you've" for "you have" and addressed others by titles such as "Master", "Mistress", "Doctor-Master" (to refer to the Doctor) or "Young Master" (Adric and in one instance Clyde). Though he did not seem to resent his subordinate status, he tended to side with the Doctor's companions over the Doctor himself and at times showed a dark side, regarding other artificial intelligences with contempt (DW: The Invasion of Time) and relishing a brief chance to act as a figure of power (MA: The Well-Mannered War)

He usually did not engage in computer-like literal thinking, though on one occasion he followed Romana's instructions to "forget it" to the letter and erased all his knowledge of tennis from his memory banks. (DW: The Stones of Blood)

Because of him having great intelligence, he likes to board people with facts and does not immedinately stop when asked as he did to Leela on Pluto. When being told that he would have to stay behind in the TARDIS, K-9 would often argue giving the Doctor reasons why he should go such as "he would be a good dog." This shows K-9's willingness to assist the Doctor. He also has showed to have great intellegence and skill at chess as he was able to beat the Doctor in six moves (This may only be becuase he is programmed with all chess games since 1886.) (DW: The Sun Makers, The Androids of Tara) K-9 has revealed to have a aggression mode. (DW: State of Decay)
