Marduk appeared in the Hulu television series "Helstrom" played by Mitch Pileggi. Fictional character biography. Marduk Kurios is a high level demon and ruler of one realm of hell. Like many other demons, he has falsely taken on the titles of Satan, Lucifer and The Devil in order to further strengthen his power and devotion. It was revealed that he was actually the biblical  Lucifer of the Abrahamic religions, as the N'Garai told his daughter Satana when they were hunting her in revenge, that in pre-historic times her father repelled their invasion of Earth as the head of Heaven's army. In ancient times the Sumerians worshipped Marduk after seeing a previous battle his legions of hell took part in on Earth. Intrigued by this new worship he kept track of the mortal realm over the centuries. He became enamoured by a family of satanists called Hellstrom and took the shape of one of them. In this guise he married the mortal Victoria  Wingate and soon after moved to Lake Fire, Massachusetts. There Victoria gave birth to Daimon Hellstrom, and a year and a half later gave birth again, this time to Satana Hellstrom. Over the years Marduk could see that his son did not care for his dark family legacy and instead lavished affection to his daughter who did. While performing a ritual with his daughter involving animal sacrifice, Victoria accidentally walked in and discovered Marduk's true nature. Driven insane, Victoria spent the remainder of her life in an asylum where she kept a diary she meant to give to Daimon  once he was old enough to understand. Marduk took Satana with him to his hell realm while he left Daimon on Earth to be cared for by servants. Upon his 21st birthday Marduk invited his son to rule by his side, offering eternal life and power. Daimon rejected his father's wishes and stole Marduk's Netheranium trident, taking with him a portion of Marduk's power. Thus the rivalry between father and son began. Marduk then tested Satana's loyalty by having her battle four sorcerers. Killing them she discovered that her father was behind the plot. When she  was confronted by him Satana failed to kill one of her new allies in honor of her father. This angered Marduk and he banished Satana to remain on Earth until her first mortal death. In a battle with the Defenders, Daimon's evil soul was released and he agreed to serve his father in hell. During Daimon's final training Marduk asked Daimon to kill a human in his honor. When Daimon failed to comply Marduk revealed that although he has lived under many faces over the centuries that not all of them have been evil. He told Daimon that  he was secretly pleased with his choice but then banished him to Earth, no longer under his care. Daimon eventually learned his father's true name from the witch Lavoisin. When next he confronted his father he used this name and received a black halo over his head and became the new ruler of his father's realm in hell. Greatly reduced in power, Marduk tricked the male witch Andrew Kale into opening the Tome of Zhered-Na. In doing so the demon Hellphyr was released. The Hellphyr then began to attack various magical persons in order to steal their  power and kill them shortly after. In causing this, Marduk had hoped to rid the world of a good percentage of its magic users in order for him to acquire a better rank among magic's stairway. Marduk offered Satana the opportunity to help him in this scheme and thus receive a higher standing herself in the realm of magic. Refusing his offer, Satana killed the Hellphyr with the help of her fellow witches Jennifer Kale and Topaz. In doing so Marduk made enemies of both his children as he searches for another way to regain his previous level of  power. Despite the continuing conflict he has with his children, it was revealed that Marduk still receives offerings of human souls from his daughter Satana. For every nine souls she devours, she offers her tenth victim's soul to her father. During the "Chaos War" storyline, Marduk is among the entities (and is confirmed to indeed apparently be in fact the most powerful demon in Hell, as the Chaos King called him "the Devil powered by all of Hell's fire") that are defeated by Amatsu-Mikaboshi and added to the ranks of his army of slave gods. During the  Fear Itself storyline, Marduk Kurios attended the Devil's Advocacy where they talked about the Serpent's actions on Earth. Marduk Kurios taunted Mephisto during this meeting. Powers and abilities. Not much is known about Marduk Kurios' powers, but are mentioned to be more powerful in his part of Hell than on Earth.
