Hellstorm

The Hell-Lords had long desired to sire a child with a human woman for use as a gateway to gain further power. A demon calling himself Satan took human form and established the trappings of a mortal life for himself near Fire Lake, Massachusetts. Keeping his true identity a secret, he married a young woman, Victoria Wingate. Daimon was born to the "Hellstrom's" a year later with a strange pentagram-shaped birthmark on his chest. His sister, Satana, was born when Daimon was three.

When Hellstrom was a young adolescent, Victoria interrupted a ritual sacrifice "Satan" had staged in their basement involving the participation of Satana. Traumatized to the point of hysteria, Victoria was institutionalized. She eventually regained enough of her sanity to write a full diary describing her life with the demon before she died. Hellstrom and his sister meanwhile were placed in separate orphanages, and "Satan" disappeared to his netherworld domain, where he eventually brought Satana.

Hellstrom ultimately entered a monastery, hoping to become a priest. Shortly before being ordained, however, Hellstrom received legal notification of his inheritance of his father's house, where he found his mother's diary and learned the truth about his birth. At that point, "Satan," aware of his son's new knowledge, directed him telepathically through the house's secret basement interdimensional passageway to the demon's netherworld domain, or "Hell." Hellstrom's father beseeched his son to disregard his mother's diary's warnings and serve him in Hell. However, when "Satan" transported Hellstrom back to Earth, Hellstrom decided to dedicate himself to fighting his father's evil. He immediately returned to Hell in an attempt to battle "Satan". Although he failed to defeat "Satan" outright, Hellstrom managed to pit many of "Satan's" slaves against their master as well as to steal the satanic trident of "Satan" and a demon-drawn chariot before returning to Earth. Hellstrom also discovered the powers of the Darksoul that he had inherited from his father. He declared himself the Son of Satan, and for the next several years battled many manifestations of demonic evil on Earth as well as other realms.
