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

 * Mark Gatiss coined the name.
 * The orange Dalek cannot be directly confirmed as Scientist, but it seems likely as the blue Dalek is Strategist, the white is Supreme, the yellow is Eternal and the red is Drone.
