KMC Forums - Son of Satan vs Zauriel

Daimon Hellstrom was the son of a demon which called itself Satan and a mortal woman named Victoria Wingate. Daimon and his sister, Satana, were trained by their father in the art of magic, tapping into the power granted them by their dark heritage. However, while Satana embraced her heritage, Daimon clung to his humanity. When their mother discovered who her husband really was, she was driven mad. Daimon and Satana were separated and put in different homes after his mother was institutionalized and his father vanished back to Hell. Daimon grew up in an orphanage, never hearing a word from his father or sister. He became a professor of anthropology at a prestigious university. He then set himself up as an occult investigator and defender of humanity, battling dark arcane forces - primarily those of his father - under the name of the "Son of Satan".

Eventually, Daimon joined the Defenders. He became a member in good standing, eventually marrying his teammate Patsy Walker, alias Hellcat. They retired, but Daimon's heritage drove Patsy mad. She was institutionalized and later committed suicide.

Daimon, now calling himself Hellstorm, ultimately discovered a way to finally defeat his father. Daimon discovered his father's true name - Marduk Kurios - and used the power of this knowledge to finally kill him. Daimon became the new "Satan", ruling over his father's Hell. He used this power to allow Hawkeye and his Thunderbolts to return Patsy from the dead.

In the Hellcat miniseries, Daimon told his wife that he was never truly the son of Marduk Kurios: his true father was Satannish, who was himself the son of the Dread Dormammu. Daimon claimed he had been fathered as part of a plot to take control of the various "Hell" dimensions. These claims, however, heavily contradicted Hellstrom's established history. It has since been established that Hellstrom was deliberately lying to Patsy when he made these claims; his love for Patsy led him to push her away in hopes that she would be happier without him.
