Lupine Wavelength Haemovariform

Biology
Lupine Wavelength Haemovariforms have Humanoid bodies, but can walk on all fours (TS: Tardisode 2). They have fur covering their bodies and wolf-like heads. Haemovariforms breed by bite. They cannot be killed by bullets, only the moonlight that they thrive on. They also see in black and white. (DW: Tooth and Claw)

Life Cycle
Haemovariforms reproduce via bite. When bitten, a victim becomes somewhat insane as well as telepathic. Their eyes also become completely black. In a full moon, the body will go through a complete transformation, until they become a Haemovariform. This presumably lasts till dawn. If a victim isn't fully bitten, then they keep their sanity. However, they have carnivorous qualities and may transform on full moons. (DW: Tooth and Claw)

Technology
Haemovariforms have basic spacecraft. (TS: Tardisode 2)

History
A Haemovariform crash-landed on Earth in the 15th century. It bit a crofter, that began its reign of terror. (TS: Tardisode 2) Father Angelo's Brethren turned from God and began to worship it, every now and then, providing a new body. Soon, it wound up in a young boy's body. The Brethren managed to tame it whilst in wolf-form by tricking it into believing it was allergic to mistletoe. It wanted to begin the "Empire of the Wolf", planning on biting Queen Victoria and taking control of the world. The Brethren managed to plot a scheme to get Victoria to stay at Torchwood House, however Prince Albert and George MacLeish had already devised a plan to kill it, using the Koh-i-Noor and a "telescope" to drown it in moonlight. When she arrived, a huge battle broke out between the Brethren and Victoria's soldiers. The Doctor managed to work out how to kill it and used the Koh-I-Noor against it, but not before it bit Victoria. Seeing as it couldn't quite complete the transition, it is unknown whether she has partially become a Haemovariform, transforming on full moons. It is also possible that the entire Royal family are partial Haemovariforms. (DW: Tooth and Claw)
