You may wish to consult Zero (disambiguation) for other, similarly-named pages.

Zero was a Lord Cardinal of the High Council of the Time Lords. Like the Doctor, he was a Prydonian. He was a member of the Council of the Great Mother, and specialised in the politics of regeneration.

Despite already having the title of Lord Cardinal, the Fifth Doctor stated that Zero was only "well on his way to getting a seat on the High Council". (AUDIO: Spring)
