Ancitif is a major antagonist in the 1st season of Sleepy Hollow TV series. He's a possessive demon who serves Moloch.
In the episode The Vessel, Ancitif threatens Frank Irving's daughter, Macey, saying that he will kill the girl unless Frank gives him Washington's Bible. Ancitif possesses several police officers, including Luke Morales and Devon Jones, whom he murdered. When Irving didn't give him the Bible, he possessed Macey and forced him to give him the Bible. That failed, and he was sent back to Hell by Crane, Abbie, and Jenny Mills.
By using a lantern that exorcises evil spirits from possessed people that was given to Benjamin Franklin by French people while he was visiting France, Ichabod Crane rescued the possessed Macey and Ancitef was exorcised to whence it came.
