Due to his angelic and spiritual nature, Lucifer needs a human vessel in order to interact directly with the physical world. Lucifer seeks out a man named Nick, whose wife and baby had recently been murdered. As revealed in Season 14's "Damaged Goods," Lucifer himself arranged for the murders through the demon Abraxas so that he could manipulate Nick. Tormenting Nick about the tragedy, he casts illusions such as a baby crying and blood pouring from the crib, eventually appearing to Nick in the form of his late wife Sarah. Openly admitting his identity to Nick, he tries to gain sympathy by telling Nick he was punished for loving God too much. He then convinces Nick to be his vessel by promising to get vengeance against God for allowing his family to be murdered. However, Lucifer later reveals to Sam that he is the true intended vessel. By "Abandon All Hope..." it is shown Nick's body, being a temporary vessel and not his "true" vessel, is incapable of containing Lucifer's immense power and is beginning to wear down; revealed in "Two Minutes to Midnight" he has to consume gallons of demon blood to keep his vessel from combusting. He forms a ritual to summon Death and when the Winchesters, Harville's and Castiel arrive, he traps Castiel in holy oil and sends Meg after the others. After being ambushed by the brothers he is shot with the Colt but survives; he then reveals his status as one of five things in creation immune to the Colt; while the brothers escape with Castiel's help, he manages to summon Death and bind him under his control.
