Scientist Dalek

The Scientist Dalek was an orange, specialised Dalek of the New Dalek Paradigm. As with their fellows bar the Eternal Dalek, the sense globes on their base unit were coloured dark silver. The first one was created by the Progenitor in 1941.

History
The original Scientist, along with the other original four Paradigm Daleks (the white Supreme, yellow Eternal, blue Strategist, and red Drone), were created when the three survivors of an encounter with the Doctor tricked the Eleventh Doctor into allowing them to activate the Progenitor device. It escaped through a time corridor with the others and went on to help rebuild the Daleks. (TV: Victory of the Daleks)

Several Scientist Daleks patrolled Kaalann and studied the Varga plants which infested the capital. One Scientist Dalek externally guarded the Visualiser room. (GAME: City of the Daleks)

At least one Scientist Dalek, designated Unit Three, was captured and taken aboard Station 7. Several Scientist Daleks were part of the platoon led by Chief Strategist that attacked Station 7, with several other Strategists and Drones under its leadership. From the command ship, Scientists transmitted control signals calling all Robomen and Ogrons detained on the station to kill all humans, while others fed static electricity to the station's floors allowing captured Dalek technology to reactivate so they could salvage their equipment for analysis and repair.

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)

Dalek Scientists were present in the Dalek Command Node when the Daleks invaded London in the year 2106 using a piece of the Eternity Clock. They were likely destroyed when the Doctor set the gas pipes built underneath the Command Node to explode. More Scientists were present on the Dalek Emperor's Flagship. (GAME: The Eternity Clock)
