Father Angelo (played by Ian Hanmore) was a religious zealot who commanded a group of fanatics called the Brethren in the Doctor Who episode "Tooth and Claw". He and his followers had devoted themselves to serving a malevolent alien life-form known as a Lupine Wavelength Haemovariform which strongly resembled the werewolf of myth and legend. This werewolf was determined to take over the Earth and intended to do so by transferring its essence through its bite to Queen Victoria, monarch of the British Empire during the 19th century. Angelo and the Brethren planned to divert the Queen's journey across Scotland in 1879 and bring her to Torchwood House. The zealots took control of the house and blackmailed Sir Robert MacLeish into keeping the Queen inside whilst they prepared for their ritual.
As the werewolf began its rampage inside Torchwood Manor, Angelo revealed his treachery. However, after six previous attempts on her life, Queen Victoria was hardly defenseless and brandished a gun from her purse, using it to shoot Angelo.
