Lupine Wavelength Haemovariform

Lycanthropes are a sapient race of werewolf like creatures from the doctor who universe.

Physiology
After transforming or taking over the host, they stand somewhere around 7-8 feet tall, are Bipedal, have significantly improved musculature (probably regardless of the hosts build or stature), long forelimbs and hind limbs (although the forelimbs appear marginally larger.).

Unlike thier mythical counter parts they have no weakness to silver and are extremely resiliant to close range projectile fire (as witnessed in the episode "Tooth and Claw" when one recieves a volly of point blank musket fire, which has no apparent effect on it) however they do appaer to have a slight aversion to mistletoe.

Appearances
"Tooth and Claw" (although they are referenced in many novelizations)
