Powers
Abbadon was known as "the Devourer" for his ability to devour life. His very shadow would kill humans, but his abilities were intended to feed on the Dark. (TV: End of Days, PROSE: The Twilight Streets)

Biography
Abaddon was an ally of the Light, who fought against Pwccm and the Dark. They fought together for centuries, travelling the dimensions until they were caught up in the Cardiff Space-Time Rift. (PROSE: The Twilight Streets)

In 1827, an archaeological expedition excavating the ruins of Babylon found a stone tablet depicting a Demon standing above a city. (WEB: torchwood.org.uk)

In 1876, the Cardiff Rift was opened in Tretarri, where Abaddon and Pwccm fought. Though Abaddon was ultimately imprisoned beneath the Rift and appeared to be defeated, in reality he faked the loss so that he could gain power. He also sent his servant, Bilis Manger, to have the event recorded in a special diary, which would be used later to free him. (PROSE: The Twilight Streets)



In 2008, Bilis set in motion a series of events designed to manipulate the Torchwood Three team into using their Rift manipulator to open the Rift and release Abaddon. Bilis' plan succeeded, and Abaddon was freed and rampaged through Cardiff; killing thousands with his shadow, until the immortal Jack Harkness stood in his way. The Demon's shadow eventually killed Jack, and Abaddon died himself in the process due to the excess life from Jack. (TV: End of Days)

The Xylok Mr Smith knew of Abaddon. (TV: Revenge of the Slitheen)



Following the defeat of Abaddon, the Light was greatly weakened and was forced to fight against the Dark and Pwccm on their own. After Torchwood sealed the Dark away and sent the Light back into the Rift to protect it, Abaddon's ashes appeared out of the ground and were recovered by Bilis Manger to be buried outside of Britain.
