Second Doctor

Habits and Quirks
The Second Doctor dressed similarly to the First Doctor, though in far less natty fashion, the pants now clownishly large and the cravat replaced with a bow tie. He abandoned the blue signet ring as it no longer fit him. In his first adventure on Vulcan he possessed a tall stovepipe hat, never seen subsequently. He also possessed a recorder which he played to concentrate or while under stress.

On Vulcan, Scotland ("The Highlanders") and Atlantis ("The Underwater Menace"), he posed as or disguised himself as other people, sometimes positively relishing the chance. Less willingly, he also impersonated Salamander, the Second Doctor's physical double.

The Second Doctor introduced several qualities later picked up upon by future incarnations. The Doctor first showed interest in Tibetan Buddhism to us in this incarnation ("The Web of Fear"). He also first revealed to us and his companions the Five Hundred Year Diary ("The Power of the Daleks"), his sonic screwdriver ("Fury from the Deep") and the alias Doctor John Smith ("The Wheel in Space", all of which he would return to in later incarnations. His ability to pull almost any object from his pockets originated with him, also.

Mysteries and Discrepancies

 * The Second Doctor showed a certain familarity with the Cybermen tombs on Telos ("Tomb of the Cybermen"). Additionally, the Cyber-Planner recognized the Second Doctor and Jamie from Planet Fourteen not shown on screen ("The Invasion").


 * Evidence suggests the Second Doctor's life continued some time after his trial by the Time Lords.
