Vanir

Vanr (plural Vanir) is the Norse Fertility God of Wisdom and Future appearing in the Season 1 episode Scarecrow in Burkitsville, Indiana.

Scarecrow
The Vanr is the embodiment of a Norse Pagan God who, in return for a sacrifice, grants the presenters with wealth, security and protection from diseases.

The residents of Burkitsville falsely tell travelling tourist couples that the backline of their car needs repairing and will be ready by sundown. During this time they will feed the tourists as a "last meal" for the Vanr.

The Vanr possesses a scarecrow at which time it will be patrolling the vineyard for a male and female. The Vanr then devours his victims in ritualistic fashion beginning usually with the male.

Hunters Sam and Dean Winchester were contacted by their father, John Winchester, who informs the brothers of the Vanr's victims and sent on his trail.

Sam departed firstly to reunite with his father in California leaving his brother Dean to hunt the Vanr.

Dean arrived in Burkitsville in time to find a potential couple to be sacrificed that night to the Vanr but they were saved by Dean as he escorted the couple back to their broken vehicle warding off the Vanr with rock salt.

The community citizens of Burkitsville were aware of the Vanr and were responsabile for both sending them to Orchard Lane and causing their car to break down at the location.

Dean was eventually offered as the next sacrifice along with a town member, Emily Jorgeson, both tied to two apple trees on the Orchard Lane Vineyard.

The Vanr rose that night and instead murdered Emily's Uncle and Aunt Harley and Stacey Jorgeson, who were closer to the podium, by inserting his hook into Harley's chest and wrapping his right arm around Stacy's throat and dragging them off.

The two were devoured and the Vanr left the body of the Scarecrow. The next day Dean incinerated the First Tree, the calling mark of the Vanr.

The Vanr was destroyed as a result and was unable to inhabit the scarecrow again.

Powers
The Vanr can grant powers and wealth as well as manifest in and out of the scarecrow.
