Anubis

Anubis is the Egyptian god of the dead and judgement.

Background
Anubis is considered the guardian of the dead and the son of Osiris. The Ancient Egyptians believed that when one dies Anubis would weigh their heart on his scale against justice's feather. After God left Heaven needed a new judge of souls. Anubis was regarded as the obvious choice and was enlisted to work with Heaven to ensure that the souls met their proper destinations.

Season 14
Lily Sunder was approached by Sam and Castiel to help resurrect Jack Kline after he had died. The former angel killer believed it was possible to bring the Nephilim back to life using Enochian magic through the use of his human soul. For her cooperation Lily wanted to be ensured that when she died that she would be granted entry into Heaven. Unfortunately Castiel informed them that Anubis was the one they needed to speak to.

After performing the ritual to summon the god, Anubis appeared before the Winchesters and Lily. The god was surprised as the Winchesters 'files' came across his desk a couple of times.

Powers and Abilities
Anubis is a powerful deity regarded as the judge of the dead, but to his own admission he doesn't decide who goes into Heaven or Hell, but is based on the actions of the soul.
 * Teleportation - Anubis had the ability to immediately appear or vanish into thin air.
 * Immortality - Anubis is thousands of years old and retained the appearance and health of a middle age man. He has an infinite lifespan and is not subject to old age. According to his own testimony, even the Winchesters could try to kill him and it wouldn't work.
 * Soul Reading - Anubis can measure a beings soul using his scale, which ironically is an abacus. Using it a medium he can determine if one is worthy of Heaven or condemn to Hell.

Trivia

 * Anubis is usually portrayed as a jackal-head human.
 * Anubis is quite a humble deity as he is comfortable in allowing Death and the reapers face-time while he handles things in the back.
 * Despite the Winchesters incapacitating his father Osiris, he doesn't seem to hold it against them, even laughing at Dean's witty joke at his job in condemning souls.
