The Cursed God is the suspected main antagonist oe the Night. It is believed in Season 1, while unconfirmed, the Society Against Evil had fought the Cursed God at some point in the past before the events of The Estate. In Season 2, the Cursed God had given The Sorceress her powers and passed the Crown of Oblivion down to her, before it was destroyed by the Society Against Evil. While the Cursed God did not have much activity in Season 3, it is speculated The Carnival Master had been guided by the Cursed God into attempting to take over Everlock, before it was locked in time by the Society Against Evil. In Season 4 it is revealed that he has been around since at least the Prehistoric Era, where there was a statue in his likeness. It is discovered by The Caveman and Cavewoman. However, it kills The Cavewoman after it is dug up. After The Raptor’s Feeding Pit Challenge, it possesses the Caveman. He is voiced by Matthew Mercer.
