Werelok

The Werelox (singular: Werelok) were a space-faring species of lycanthropes employed by the Daleks. The Doctor was nearly turned into one. (DWM: The Dogs of Doom)

They were members of the Galactic Federation, and three Werelox athletes were present at the Olympics in 3999. (EDA: Placebo Effect)

They had venom ducts in their claws and fangs which could transform humans and Time Lords into Werelox, although they would still maintain their consciousness. These Werelox were destructive and would lash out at surrounding objects. (DWM: The Dogs of Doom)
