Baldur

Baldur was one of the Gods who met with the other deities to try to work out a way to stop the Apocalypse. Along with Kali, he appeared to be one of the most powerful of the gods present. It was also implied that he was in some sort of relationship with Kali. Baldur was killed by Lucifer after trying to stop him. He was the Norse god of light, love, and beauty.

Physical Appearance
Baldur, a god with black hair and dressed in a black suit, didn't like the idea of the Apocalypse coming. So he arranged for it to be stopped along with the other Pagan Gods.

Personality
Unlike his fellow gods, Baldur was a respectful and civilized gentleman. He had a very fair persona, even referring to Sam and Dean as guests of honor. He did not believe Lucifer had the right to own the planet or cause the Apocalypse.
