The Thirteenth Doctor (Jodie Whittaker)
The Thirteenth Doctor was the first female incarnation of the Time Lord known as the Doctor and the second incarnation of the Doctor’s second regeneration cycle granted by the Time Lords during the Siege of Trenzalore.
After being separated from her TARDIS during her post-regenerative trauma, the Doctor was assisted in her recovery by Graham and Grace O’Brien, Ryan Sinclair, and Yasmin Khan. Following a battle with the Stenza she dubbed Tim Shaw, that resulted in Grace’s death, the Doctor inadvertently brought Graham, Ryan, and Yasmin with her in her search for her TARDIS.
After finding the TARDIS, the Doctor initially planned to take Graham, Ryan, and Yaz back home, making several accidental trips along the way. After briefly returning to Sheffield, Graham, Ryan, and Yaz officially joined the Doctor in her travels; they shared a close, family-like bond, calling themselves Team TARDIS.
