The Second Doctor was the second incarnation of The Doctor in the Classic Doctor Who.
Though outwardly warm, bumbling, and clownish, the Second Doctor also had a darker, more cunning aspect to his personality — one which he usually kept hidden in order to carry out his plans. Regenerating when his first incarnation gave in to old age and fatigue following his fight with the Cybermen, this new incarnation was the product of the Doctor's first regeneration. He also was a bit of a musician because of his recorder and he was also the first to use a Sonic Screwdriver and the first to wear a bow tie, a look later again used by the Eleventh Doctor .
He was later captured and was forcibly regenerated into the Third Doctor by his race, the Time Lords, who then exiled him to Earth.
- He appears in the Classic Who Minifigure Series.
