Lupine Wavelength Haemovariform

Biology
Lupine Wavelength Haemovariforms had Humanoid bodies, but could walk on all fours (TS: Tardisode 2). They had fur which covered their body and wolf-like heads. Haemovariforms breed by bite. They could not 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 reproduced via bite. When bitten, a victim became (somewhat) insane as well as telepathic. Their eyes, became completely black. In a full moon, the body would go through a complete transformation, until they became a Haemovariform. This presumably lasted till dawn. If a victim was not fully bitten, then they keep their sanity. However, they had carnivorous qualities and may transform on full moons. (DW: Tooth and Claw)

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

History
A Haemovariform crash-landed on Earth in the 15th century. Father Angelo's Brethren turned from God and began to worship it. Soon, it took 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 and possessing 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 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 had partially become a Haemovariform, transforming on full moons. It is also possible that the entire Royal family were partial Haemovariforms. (DW: Tooth and Claw)
