Ninth Doctor (Scream of the Shalka)

The melancholic ninth incarnation (NOTVALID: Scream of the Shalka) of a Time Lord known as the Doctor met a barmaid Alison Cheney in the small Lancashire town of Lannet. Together, they fought to save the world, and defeated the silicon-based Shalka. Afterwards, Alison left with the Doctor in the TARDIS. (NOTVALID: Scream of the Shalka)

The two, along with the android Master, shared at least one more adventure together, involving vampires. (NOTVALID: The Feast of the Stone)

Characteristics
This incarnation of the Doctor was serious, and often angry, but wasn't averse to the odd bit of fun while having the bearing of an aristocrat. He was angry and reluctant to listen to the mysterious force that ordered him around time and space. Unlike previous incarnations, the Ninth Doctor was reluctant to take Alison on as a companion due to the untimely passing of his previous companion. While brave and heroic, the Doctor was more reluctant to get involved in the events taking place in Lancashire. (NOTVALID: Scream of the Shalka)

He kept an android version of the Master in his TARDIS, who was unable to leave the TARDIS. He was willing to turn the Master off and back on again without hesitation, and was unable to grasp how that might horrify Alison, as it not only showed what he will do to achieve his goals if he believes it necessary, but also raised the possibility that he might do something similar to her if he believed it necessary. (NOTVALID: The Feast of the Stone, NOTVALID: Scream of the Shalka)

Habits and quirks
The Ninth Doctor drank alcohol. He carried an inhaler, which he called his "huffer". (NOTVALID: Scream of the Shalka) He carried a mobile phone, taken from a charging cradle hidden behind the telephone panel in the TARDIS' police box shell. Shaped like the TARDIS, the phone was in fact part of the TARDIS itself. The Doctor displayed a fondness for singing and had a repertoire of showtunes. He was friends with Andy Warhol, who wanted to paint a picture of him and his eight previous incarnations. He kept a signed manuscript copy of Hamlet in his TARDIS. (NOTVALID: Scream of the Shalka)

Behind the scenes

 * According to DWM 464, the Doctor had been a lover to his companion, the daughter of the Lord President and he had retired to Gallifrey. After some time, an unknown alien had invaded and killed all Time Lords. All except the Doctor's companion promptly retreated to the Matrix. The Doctor and the Master "sent the aliens packing", destroying the Master's final form in the process causing the Doctor to construct an android body confined to his TARDIS. The Time Lords use their power to "send the Doctor off to solve the most dangerous problems in the universe".
 * There is a similarity between the Shalka Doctor and the incarnation of the Doctor seen in PROSE: The Cabinet of Light. However such a similarity is entirely coincidental, as author Daniel O'Mahony worked on this story with no information that a new incarnation of the Doctor would be introduced just months after the publication of his novella.
