The Apostles of the Beast were individuals that directly and indirectly protected and aided Damien from those who may have discovered that he was the Antichrist. They also made sure his rise to power would be without any obstacles and if any arised, they were effectively dealt with.

Mrs. Baylock took care of Damien as a young child. Sergeant Neff, Ann Thorn and Paul Buher oversaw Damien as a teenager as did Murray the chauffeur. All 5 were Apostles of the Beast.

As an adult, Damien's closest Apostles of the Beast were Harvey Pleydell Dean and the Disciples of the Watch.

They are also known as the Servants of Hell, Disciples of the Watch and the secret disciples of Satan.
