Scientist Dalek

The Scientist Dalek was an orange Dalek created by the Progenitor device. It acted as a scientist for the new Dalek Empire. It escaped through a time corridor. The name suggested that the Scientist would be in charge of sciences and technologies for the Dalek strategems and design bio and mechanical weapons. (DW: Victory of the Daleks)

Behind the scenes
