The 9th Doctor:
Rowen AtkinsonThe 9th Doctor and Emma
The 9th Doctor has had but one appearance, and obvisously this is not intended to tie-in with the series at all. In this story, The Curse of Fatal Death, the Doctor is once more at war with the Master. However, he is due to be married to his latest companion, Emma (Julia Sawalha). Things take a turn for the worse when the Master (Johnathon Pryce) engages in time travel, and sets a trap for the Doctor. The Doctor out-does the Master and sets a solution to the trap. The Master spends many centuries down a sewer as a result. The Master teams up with the Daleks once more, and the Doctor is captured. The Daleks obtain (from the Master) the key to controlling time, but the Doctor tries to stop them. The Daleks finally exterminate the Doctor.
The 10th Doctor and Emma
The 10th Doctor, Richard E Grant, doesn't last long. The Doctor recovers from near death, only to be killed by a power surge.
The 11th Doctor
The 11th Doctor, Jim Broadbent, is also killed in a similiar way.
The 12th Doctor
The 12th Doctor, Hugh Grant, is killed by a burst from the Dalek's time controller, from which there is no regeneration.
The 13th Doctor, Emma, and the Master
The Doctor overcomes this burst, and regenerates for the 12th time, only this time he regenerates as a she, and becomes a Time Lady. Strangley, the Master likes this Doctor and the two come an agreement. The Daleks reform as the Doctor has saved them from death.
