Abraxas

Abraxas was a demon known to Lucifer who brutally murdered Nick's family.

History
Abraxas was a demon known to and loyal to Lucifer.

In 2009, The Apocalypse had begun when Lucifer was released. On orders of Lucifer, he visited the house of Nick, Lucifer's future vessel. Nick's wife Sarah spotted Abraxas and called the police to report a prowler. When beat cop Frank Kellogg arrived, Abraxas introduced himself then possessed the man. In Frank's body, Abraxas brutally murdered Sarah and her son Teddy with a hammer before leaving Frank in his police cruiser and departing his body.

In 2018, after the death of Lucifer, Nick began seeking out his family's killer for revenge, eventually tracking down Frank Kellogg. Frank told Nick of his encounter with Abraxas outside of Nick's home and his memory lapse before waking up in his cruiser covered in Sarah's blood. Nick realized that Lucifer knew the name Abraxas and that Abraxas was a demon who had possessed Frank to murder his wife and son. Nick recognized that the murders were not Frank's fault, but beat him to death in revenge anyway as it was his hands that Abraxas used to murder Sarah and Teddy.

Abraxas and another demon were confronted by Mary Winchester who killed the other demon but Abraxas proved hard to handle. Mary resorted to trapping him in an Enochian puzzle box and storing it away. Soon, Nick found Mary and interrogated her on the demon's location, to which she reluctantly gave up. For answers, Nick kidnapped a security guard to host him(since he and Mary couldn't). Once freed, Abraxas took the guard as a vessel and was amused to see Mary before Nick questioned him. Abraxas was informed that it was Nick who he was surprised to see alive while told Lucifer was dead.
