The Haemovores had enormous strength and power, and could climb sheer surfaces with ease. They were resistant to bullets, and could only be killed by a stake to the heart. Also, Haemovores had razor-sharp claws, which they used to kill people. Haemovores could even weld metal with their hands, and older Haemovores built up armour made of metal they collected and melted together. The Haemovores could be stopped with a psychic barrier, which in humans was created by the mental processes associated with strong faith; the Doctor (and, presumably, other Time Lords and psychically-aware beings) could create this barrier at will. In the presence of the barrier, the Haemovores often responded with ear-splitting shrieks.
Haemovores were known to only hunt in the fog or mist.
The Haemovores communicated with each other telepathically. This could be detected by telepathic humans. They could also telepathically control humans, making them easier to feed on. They were all controlled by Ingiger, who could kill them with a thought. (PROSE: The Curse of Fenric)
Life cycle edit
The Haemovores started life as humans, who were changed by other Haemovores. At first, the only signs of change were pale skin, large red lips and sharp claws. They still had their minds and memories, but a more feral mindset. As they aged, their appearance started to change: Their skin grew slimy and wrinkled, their eyes were swollen shut and their mouths turned into suckers for feeding. After a century, they were completely transformed into Haemovores.
The Haemovores evolved on Earth circa 500,000 AD, after the planet was ruined by industrial waste. They lived under the chemical swamps, in the saline solution of the ocean, consuming plankton and sometimes ganging up on a great whale to feast. (PROSE: Goth Opera) The last Haemovore was Ingiger, who believed himself the last living creature on Earth. Fenric brought Ingiger back in time to Transylvania some time after the 10th century, where he fed on the Vikings who had taken the flask containing Fenric. He and the Haemovores followed them, and after they were killed by the pirate Hemming, followed him to Maiden's Bay.
Though Hemming and all his men were killed by the Haemovores, Hemming had buried the flask beneath St. Jude's Church where they could not get it. Instead, the Haemovores were forced to wait.
Six months later, the Haemovores in Maiden’s Bay were awoken by Fenric to attack the Soviet and British soldiers as part of a trap to defeat the Seventh Doctor. Once they had served their purpose in this plan, Fenric ordered Ingiger to kill the Haemovores with a thought. Using the poisons made by the nearby base, Fenric intended to pollute the world, causing the future that created the Haemovores. The Doctor was able to convince Ingiger to betray Fenric; the Ancient One killed both itself and Fenric by going into the isolation chamber with Fenric and releasing a poison.

The Haemovores existed as a possible future of humanity, their time stream accessible to time travellers. (PROSE: Goth Opera) The creation of the Haemovores appeared to be a predestination paradox and, after the Doctor's defeat of Fenric, this future may not still exist.[source needed]
