The Doctor (Scream of the Shalka)

An incarnation of the Doctor helped Honoré Lechasseur defeat Mestizer.

Biography
The Doctor regenerated after being shot in the back by Mestizer in the London docks. He spent several months lying low while Honoré Lechasseur conducted his investigations for him. (PROSE: The Cabinet of Light)

Under the alias of Dr Smith, he tried to stop the Sodality from existing, so that hundreds of time sensitives would not be killed by them. After failing to gain the support of the High Executioner in erasing the Sodality from history, the Doctor departed in his TARDIS.

The Doctor set events in motion so the "Child of Time" would gain its full powers and stop the Solidarity's plans. The Doctor left in his TARDIS with the unconscious High Executioner, who was now suffering from amnesia. The Doctor dropped off the High Executioner in 1949, where she called herself by her real name, Emily Blandish, and helped the Doctor defeat Mestizer in his relative past. (PROSE: Child of Time)

Much later, while traveling with the Master (who was now in an android body), he 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. (WC: Scream of the Shalka)

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

Personality
The Doctor smoked to improve his singing voice. He had recently lost a travelling companion, which made him reluctant to take on a new one. (PROSE: The Cabinet of Light)

He was serious, and often angry, but wasn't averse to the odd bit of fun. (WC: Scream of the Shalka)

He was known to drink alcohol. (WC: 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.

Appearance
In his younger years, this incarnation of the Doctor wore a black coat with green collar, white shirt, a loose collar on the coat, exposing his neck and pronounced throat. He wore a hat and muffler. He was clean shaven on only his chin and lip and had brown hair which was receding. He was gangly but not too tall and had large hands. (PROSE: The Cabinet of Light)
