Scientist Dalek (Victory of the Daleks)

The first Scientist Dalek of the New Dalek Paradigm was created as one of five new Dalek types by the Progenitor aboard their last surviving ship above Earth in 1941 when the last three Daleks tricked the Eleventh Doctor into allowing them to activate the Progenitor device. The five new Daleks escaped through a time corridor, and went on to rebuild their empire. (TV: Victory of the Daleks)
