Chris Obi portrays Mr. Jacquel, a psychopomp deity who stands in for Anubis. Because of this, his primary duty is to accompany recently departed individuals to the ancient Egyptian afterlife (or "Duat").
In the American Gods world, Mr. Jacquel appears to exclusively instruct those who had a connection to Egyptian religion or culture while living (for example, Mrs. Fadil, who was of Egyptian descent, and Laura, who worked in an Ancient Egypt-themed casino). As a death god, Mr. Jacquel can know when individuals are about to pass away. Mr. Jacquel, in a clear nod to Anubis, may turn into a black jackal.
