Looter

Looters became a problem in London when the city was evacuated after dinosaurs appeared. (TV: Invasion of the Dinosaurs)

In an alternate timeline, Varx and Piril became looters when the Daleks invaded Urbinia. They believed they would be a low priority among those begin evacuated and so began looting phason pods instead so they could go into hiding. (AUDIO: Daughter of the Gods)
