Azazel's vessel

Azazel's vessel was the recurring vessel of the powerful demon Azazel.

In My Time of Dying
When John Winchester summoned Azazel to make a deal to save his son Dean's life, Azazel possessed this man who was a janitor at the hospital where Dean was in a coma. Azazel brought with him two demons to ensure John didn't use the Colt to kill him, but John instead made a deal: his soul and the Colt for Dean's life. Azazel briefly left the man to possess the Reaper Tessa to save Dean, but later returned to him.

All Hell Breaks Loose - Part 1
When Azazel appears to Sam Winchester in a dream, he is still possessing this man.

All Hell Breaks Loose - Part 2
Azazel continues to possess this man as he appears to Jake Talley in a dream and then in real life to give him the Colt. He later uses his body to battle Dean to the death and is pulled from it by the spirit of John Winchester. By this point, the man may or may not be dead as he is left at least unconscious by Azazel's departure. After overpowering John, Azazel returns to his body and is promptly shot in the heart by Dean, killing him. The man's body falls to the ground and the yellow disappears from his eyes as Azazel is killed. His body is last seen on the ground with smoke coming from the bullet hole when Dean tells Azazel "that was for our mom, you son of a bitch."
