The Beast was a huge demon who was constructed entirely from rock. It had two distinct curved horns and bright yellow eyes. Cordelia began to see visions of The Beast, who eventually clawed it’s way up through the Earth, emerging at the very spot where Connor was born. The Beast was brought to Earth from a Hell dimension where it was previously banished in order to pave the way for Jasmine’s entrance to the Earth. A killing machine, The Beast easily beat Angel, Gunn and Lorne and massacred many residents of L.A. - including most of Wolfram & Hart. The Beast conjured a rain of fire over Los Angeles, during which Cordelia and Connor made love - resulting in Jasmine’s conception.

By order of it’s master - who was secretly Cordelia - The Beast killed the Mesekthet, a member of an order of mystical beings known as the Ra-Tet, who was disguised as a little girl at W&H. It then hunted down and killed other members of the Ra-Tet - Ma’at, Ashet and Semkhet. The final Ra-Tet, Manjet, was killed by a possessed Cordelia in secret. The Beast pieced together the remains of the Ra-Tet - the metal wings from Ashet and Semkhet, the heart of Ma’at, the orb from Manjet’s head and the dark energy of Mesekthet in order to block out the sun.

Believing that their only hope was in Angel’s evil alter ego Angelus, who had known The Beast in the past, Angel Investigations had a shaman remove Angel’s soul and turn him into his true vampire form. Angelus stabbed The Beast with a knife made from its own bones, as the only thing that could kill the Beast was the Beast itself. The death of the Beast undid the spell to eclipse the sun.
