Mummy Martial
From Tardis Wiki, the free Doctor Who reference
Mummy Martial was one of the seniors on a human colony of Urth. She was constantly worried about invasions and became paranoid about it. She argued with Susan Foreman about being a free thinker, and wanted to use her as an ambassador. She actually sent Susan as a plague carrier to kill the invaders. She eventually found out that she wasn't a pure human. (AUDIO: For the Glory of Urth)
