History
K9
The Professor offered K9 to the Fourth Doctor as the same weight requirements made him unable to take Mark I back to Earth. (Episode: The Invisible Enemy) After adventures with Leela and the Doctor, Mark I decided to stay on Gallifrey with his 'mistress'. (Episode: The Invasion of Time)
Before this, the Doctor obtained or constructed at least one backup model of K9. Immediately after leaving Mark I behind with Leela, he unpacked K9 Mark II. This version of K9 accompanied the Doctor and his new companion on their quest to locate the segments of the Key to Time, (TV: The Ribos Operation) but the swampy terrain of Delta III made it impossible for him to join them on the planet. At the conclusion of the quest, the Shadow turned K9 to his evil will, giving K9 a sinister personality. (TV: The Armageddon Factor)
The Fourth Doctor found that K9 had contracted laryngitis and had lost his voice as a result of this. K9 was left in the TARDIS while the Doctor and Romana II battled the Daleks and Davros. (Episode: Destiny of the Daleks) During a later adventure, he remained patiently in the TARDIS, which would imply that his voice had not yet returned. (Episode: City of Death) After his voice returned, it sounded quite different and remained so for a while (Episode: The Creature from the Pit) before the familiar voice returned. (Episode: The Leisure Hive)
Overview
K9 had a personality very consistent across the models with some contact with the Doctor. He was polite and formal, with pedantry bordering on condescension. Though he often displayed feelings such as sorrow (Episode: The Invasion of Time)
When the Doctor left Sarah Jane Smith on Earth, he created K9 Mark III as Sarah's companion. The new mechanics of K9 Mark III included larger wheels and a front and back-wheel drive. K9 was also given a brand new coat of paint and a handle on top of his shell to make carrying him easier. (Episode: A Girl's Best Friend)
After K9 Mark I regenerated into K9 Mark 2, his design was radically altered. His ear probes were replaced with larger silver aerials. A set of blue lights on his head flashed when he spoke. Most of his body was dark silver and a silver dog bone was located under his neck. He seemed to have the same capabilities as Mark I but was presumably more advanced. (Episode: Regeneration)
After K9 Mark 2's apparent rejuvenation, he looked similar to his predecessor, but with a bright blue coat of paint and K9 Mark I's old collar. (Episode: The Eclipse of the Korven)
