Lupine Wavelength Haemovariform

The Lupine Wavelength Haemovariform was a type of werewolf.

Biology
The Lupine Wavelength Haemovariform had a humanoid body which resembled a bipedal wolf, but could also run on all fours. Haemovariforms had very sensitive ears. It had fur which covered its body and a wolf-like head, as well as a tail. Their vision was monochromatic. Haemovariforms were highly resistant to bullets and they were able to be made to think that they were allergic to mistletoe. The only known way to kill a Haemovariform was over-exposure to the moonlight on which they thrived, like a plant in relation to sunlight, though the Doctor indicated that silver bullets would work as well. Sharp, vicious teeth and claws were capable of ripping people to pieces. (TV: Tooth and Claw)

Life cycle
Not much was known about the species natural life-cycle, but they were capable of reproducing or migrating via a bite. Once infected, the bitten host was taken over by the invading cells.

The host would develop black eyes as if the pupils became enlarged. During a full moon, the host would undergo extreme physical changes as the bone structure changed to become more lupine in appearance.

According to the Tenth Doctor, a single cell could take at least a century to mature. If infected by a very small number of cells, he hypothesised that Queen Victoria could remain more or less human, but presumably end up passing on the infection via bites down the generational line till the Haemovariform reached maturity.

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

History
A Haemovariform crash-landed on Earth in 1540. Father Angelo's Brethren turned from God and began to worship it. It took up 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", actually a light chamber, to drown it in moonlight. When she arrived in 1879, a battle broke out between the Brethren and Victoria's soldiers. The Tenth Doctor managed to work out how to kill it and used the Koh-i-Noor against it. It is unknown whether Victoria was exposed to Haemovariform cells and had partially become a host. If so, the Doctor hypothesised that the entire subsequent Royal family might be partial Haemovariforms, which was believed by the public to be the blood disorder haemophilia. (TV: Tooth and Claw)
