Odin

"I don't know what everybody's getting so worked up about. It's just a couple of angels having a slap-fight."

- Odin referring to Michael and Lucifer.

Odin was the chief pagan deity of the Norse pantheon. While on Earth he took the form of an elderly American man in a bomber jacket with a strong Midwest accent.

Season 5
Odin was one of the deities who met with the other deities, to try to work out a way to stop the Apocalypse. He was of a laid back disposition towards the whole thing, believing it to be a "slap fight between a couple of angels". He briefly got into an argument with Zao Shen when he began mocking the latter's world turtle.

Odin said nothing during Gabriel's arrival and watched silently when Kali seemingly killed him.

Odin's casual arrogance towards the angels cost him his life when Lucifer killed him in the Elysian Fields Hotel hallway. He was last seen screaming on the floor in pain.

Lore
In Germanic mythology, Odin is a widely revered god. He is associated with healing, death, royalty, the gallows, knowledge, battle, sorcery, poetry, frenzy, and the runic alphabet. He is the husband of the goddess Frigg.

In Old Norse texts, Odin is depicted as one-eyed and long-bearded, frequently wielding a spear named Gungnir, and wearing a cloak and a broad hat. He is often accompanied by his animal companions—the wolves Geri and Freki and the ravens Huginn and Muninn, who bring him information from all over Midgard—and Odin rides the flying, eight-legged steed Sleipnir across the sky and into the underworld.

Odin is attested as having many sons, most famously the god Baldur, though this fact was not mentioned in Supernatural, despite the two appearing in the same episode.
