The celestial being known as the Angelus is the antithesis of the Darkness; a creature of pure light which seeks to facilitate order in the universe. Having emerged from the Light of Creation, the Angelus has waged an eternal war with the Darkness for many generations of history.

When Jenny Romano died, the Darkness trapped her soul in Hell as well. At some point, the Angelus took her as its new host, and used Jenny to subtly goad Jackie into freeing her. After destroying the Brotherhood, Jackie killed himself with the Siphon while the Darkness was trapped inside it, sending him back to Hell. He found Jenny there and freed her, but after a long embrace, she transformed into the Angelus. The Angelus taunted Jackie by telling him that Jenny still loved him, even after everything that happened to her because of him. The Angelus told Jackie he'd become too strong a Darkness host for her liking, so she left him stranded in Hell while she returned to bring her light back to the world
