Doctor Who: 5 Most Interesting Time Lords Other Than the Doctor

5. The Rani

An old school friend of the Doctors and the Masters, the Rani clashed with both the Sixth and Seventh Doctors for her callous experiments on, what she saw as, lower forms of life, such as human beings. Whereas the Master does evil simply for the sake of it, the Rani has a scientific curiosity behind her amoral behaviour. It could be argued shes even more successful than the Master, having been known to rule over at least two whole planets. Now, maybe if the Master wasn't so fascinated with Earth...
The Rani appeared a third time in Dimensions in Time, a Children in Need special from 1993 thats not generally considered part of the shows canon. In this two-parter, the Rani sought revenge on the Doctor by trapping all his regenerations in the TV soap Eastenders. If this intrigues you, please please dont look it up. Theres a reason its not canon.
