1. The Doctor Pleads With Davros (Genesis of the Daleks)
And of course, we have to end with the best Doctor/Davros interaction of all time, as Tom Baker’s Doctor faces Michael Wisher’s original Davros in the classic Genesis of the Daleks. Pleading with Davros to stop development of the Daleks, the Doctor asks him (hypothetically) if he would release a virus that would destroy all other living organisms in the Universe. I’m sure you know how Davros responds!
