Darksmith Agent
From Tardis Wiki, the free Doctor Who reference
The Agent is a robot used by the darksmith Collective and was an enemy of the Doctor during the Darksmith Legacy.
The Agent's metal bodywork is augmented with plastic salvaged from the wreckage of the Nestene homeworld; Polymos.
The Agent is programmed with innate understandings of the time Vortex that were found in a deactivated Gundan robot. This allows the Agent to travel on time winds.
