Zaadur

Zaadur was the dictatorial ruler of the Gandorans and the daughter of Quendril.

She became an absolute ruler by taking control of the life drink supply and rationing it. Later, she decided to conquer Earth with her army of Saurian Evolutionaries and kill all other Gandorans, whom she considered imperfect, as they were not genetically engineered as she was. When the Second Doctor and Jamie referred to the Saurians as Ice Warriors, Zaadur liked the term and renamed them as such. (AUDIO: Lords of the Red Planet)
