The Fifth Doctor was portrayed by Peter Davison.
The Fifth Doctor was the Time Lord’s most youthful incarnation up to that point in his life. As the Tenth Doctor commented when meeting him in the TARDIS, ‘Back when I first started at the very beginning, I was always trying to be old and grumpy and important, like you do when you’re young. And then I was you. And it was all dashing about and playing cricket and my voice going all squeaky when I shouted…’ But there was more to this Doctor than youthful impetuosity.
Davison portrays the fifth such incarnation, a staunch pacifist with a vulnerable side and a tendency towards indecisiveness, dressed as a boyish Edwardian cricketer. He travelled with a host of companions, including boy genius Adric (Matthew Waterhouse), alien aristocrat Nyssa (Sarah Sutton) and Australian flight attendant Tegan Jovanka (Janet Fielding), whom he had travelled alongside in his previous incarnation. He also shared later adventures alongside devious schoolboy Vislor Turlough (Mark Strickson) and American college student Peri Brown (Nicola Bryant).
