The Defenders are the prisoners of the Hell-Lords Mephisto, Satan, Satannish and Thog, who have pooled their resources together through their pawns the Six-Fingered Hand to create a Hell on Earth. Showing them an illusion of things to come, the Defenders notice that Nighthawk and Hellcat are also in their thrall. With the Defenders debating on what to do next, Son of Satan leads Hulk and Sub-Mariner on a direct attack but they are easily tossed back via Satan's powerful magics. As the team regroups, Satan reveals that Hellcat is his daughter, shocking the Defenders -- especially Daimon who was just beginning to fall in love with Patricia.

Satan reveals that he posed as Patricia's father and spawned her through her mother, then let her continue her own life unaware of her Satanic origins and aided behind the scenes to mold her into the super-hero known as Hellcat. When Valkyrie tries to talk Hellcat into helping the Defenders, Hellcat attacks and when Nighthawk tries to stop her he is tossed to the other Defenders. Mocking his son for loving his possible sister, Satan blasts Daimon when he tries to attack again. Dr. Strange then steps in and challenges Satan to a duel between the Defenders and his fellow Hell-Lords to determine the fate of the Earth. Satan agrees telling them that their key to victory is to find the light in darkness' heart and teleports them all away except for Hellcat and Son of Satan so that he can discuss things with his son.
