Delia is the daughter of the Antichrist, as seen in the superfluousness known as Omen IV: The Awakening, the direct-to-TV sequel to the trilogy. Like dad, like daughter: She rips evangelical pamphlets and does pretty much all the sine qua nons for a diabolical spawn. People die horrific deaths if they cross her, let alone make the Sign of the Cross, all while first-rate hellish energies whirl around her.
Canadian actress Asia Vieira played the devil-child. Unfortunately, the child starlet never outgrew low-budget projects. She was last seen on TV in 2006 in Gospel of Deceit.
