Darksmith Agent

The Darksmith Agent was a tall, powerful and intelligent skeletal robot with a silver skull, beautifully crafted and used by the Darksmith Collective to recover the Eternity Crystal after it reappeared on the Earth's moon and was taken by the Doctor.

It was a product of Darksmith technology, which incorporated the technology of others. It was a masterpiece of engineering programmed with the innate understandings of the Time Vortex (found in a deactivated Gundan robot), allowing it to travel on the time winds. Its metal bodywork was augmented with plastic salvaged from the wreckage of the Nestene homeworld Polymos. Its internal mechanisms were visible through a transparent outer layer, its photothermic vision allowed it to track body heat, and its brain was a computer core matrix which shared the same crypto-molecular structure as the Eternity Crystal, a product of former-brother Varlos of the Darksmith Collective.

The Darksmith Agent was capable of self-diagnosis and repair as well as a degree of independent thought, albeit one dictated by logic.

The Agent was destroyed when Zalenby lowered the landing gears of his craft and crushed it following a savage attack by the Nocturn.
