H

H was a hunter mentioned in John Winchester's Journal it's not clear exactly what his real name was but from what John describes he was a very ruthless hunter willing to abandon a dying friend in on a hunt. In the beginnng he severve a mentor to John even saving him on a hunt which is how the two met. He's the one that tells John about ceances, hell hounds and demons. To which John was skeptical he was present when John hunted Doc Benton claiming the doctor was a Revenant.

John later learned that H was a demon though John doesn't state what color his eyes were H seemed to play major role as he was suppose to get John focused on hunting. John says he killed H and that if that's what H wants for him to hunt than he will and keep hunting until he kills The Yellow Eyed Demon.

Trivia

 * As John did not posses The Colt or even know of it it's very likely H is still alive despite John saying he killed him.


 * It is ironic that as a demon he mentored John as a Hunter.
