Abaddon

Abaddon was a Demon and the son of the Beast, imprisoned beneath the Cardiff rift. (TW: End of Days) The Ood named Abaddon however, as a name for the Beast itself. (DW: The Satan Pit)


 * The Disciples of the Light, who imprisoned Abaddon's father, may have also have imprisoned Abaddon.

A 1827 archaelogical expedition excavating the ruins of Babylon experienced what seemed like omens, and found a stone tablet depicting a great demon standing above a city. (torchwood.org.uk)

Bilis Manger, considering himself Abbadon's servant, set in motion of series of events designed to manipulate the entire Torchwood 3 team into using a technological device to open the Rift and so release the demon. This done, the Rift released Abaddon and he appeared.


 * Abaddon seems to share none of the intelligence of his father and was not shown to speak or plan. There is still the possibility that he was the one who created the plot, rather than Bilis Manger himself.



The shadow of Abaddon killed any person who it fell upon and fed upon their life energy. Only the undying Jack Harkness stood in his way. He was eventually killed by Abaddon, the Demon dying in the process due to the excess life. However, Jack was ressurected by Gwen Cooper a few days later by a kiss of life. (TW: End of Days)
