Technix
From Tardis Wiki, the free Doctor Who reference
The Technix were a species of clones resembling bald, grey-skinned humans. They were employed in the Galactic Federation as workers, as well as by the Guardian of the Solar System. (PROSE: Placebo Effect) They were bred specifically for use as human calculators and had no free will of their own. (PROSE: Uranus)
Several Technix worked at Central Communications on Earth. Two others accompanied Mavic Chen to Kembel aboard the Spar. (TV: The Daleks' Master Plan)
