Scientist Dalek

The Scientist Dalek was an orange Dalek created by the Progenitor. Its role was to examine and formulate new weapons as well as to analyse the genetic and physiological make-up of the Daleks' enemies so that their weaknesses could be isolated. (DWAN: Doctor Who The Official Annual 2011)

History
The original Scientist, along with the other original four, the Supreme, Eternal, Drone and Strategist, was created by the Progenitor when the three survivors of the Crucible incident tricked the Eleventh Doctor into allowing them access to the Progenitor. It escaped through the Time corridor with the others when their plans to destroy Earth failed. (TV: Victory of the Daleks)

Several Scientist Daleks patrolled Kaalann and studied the Varga plants which infested the capital. (GAME: City of the Daleks)

Several Scientist Daleks were part of the platoon led by a Strategist that attacked Station 7, with several other Strategists and Drones under its leadership. (COMIC: The Only Good Dalek)

A Scientist Dalek sent an alien family plummeting through time and space while attempting to collect all the Time Orbs. The Scientist recruited many Strategist Daleks and Drones. It also recruited big armies of Cybermen and Silurians as a distraction for the Eleventh Doctor and Amy. (GAME: The Mazes of Time)
