Fairies in Supernatural
Fairies are supernatural creatures that all seem to have originated from a place called Avalon. Coming in a variety of forms and sizes, they can only be seen by those who have been to the fairy realm or those they allow to see them. According Marion, a fairy expert, there is a fairy leader called Oberon. When summoned by a spell, they can make deals with humans, oftentimes exchanging their services for a price, such as the right to all of the firstborn sons in an area. Fairies also appear to have great power. The Leprechaun claimed to know back ways into Hell and did not fear angels or demons. In recent years, fairies have been taking advantage of UFO myths to hide their activities, as the abductions, crop circles, and bright lights they make in the sky are all often attributed to alien encounters.
Fairies are vulnerable to Iron and Silver. If someone pours salt or sugar in front of them, they have to stop to count each grain one by one. They also love cream, which, like alcohol, intoxicates them. Fairies will remain in an area until banished by a spell or leave of their own free will.
Known to come in "different shapes and sizes", their powers are dependent on the fairy at hand, as certain types hold separate, individual powers.

The different types of fairies the Winchesters encounter are:
1. A Tinkerbell-like fairy attacks Dean in their motel room. He describes her as "a little, glowing, hot, naked lady with nipples." Dean particularly notices her nipples. She also has wings. Dean kills her by luring her into a microwave and frying her. 
2. Elves work in the watchmaker Mr. Brennan's workshop as a result of the deal he made with a Leprechaun. They get drunk on the cream that Mr. Brennan buys for them and are banished when Sam reverses the ritual that Mr. Brennan used to summon them.
3. A Redcap stalks Dean. These fairies are dangerously homicidal and are known for mercilessly killing travelers who trespass their territory. Their hats are red because they soak them in the blood of their victims, and, according to lore, Redcaps have to kill regularly because if the blood dries on their hats they will die. The Redcap finally attacks Dean in his jail cell, but is banished with the rest of the fairies before he can kill him.
4. Sam encounters a Leprechaun that passes among humans as a man named Wayne Whittaker. He acts as a spokesman for a number of other fairies, and can make deals with humans that include the exchange of their labor. As Wayne, he claims to be a UFO-specialist and works to spread UFO hysteria wherever he and the other fairies go so that they can avoid detection. When he and Sam fight, it is obvious that he is very powerful, but Sam is able to spill salt in front of him and force him to count the grains. While he is occupied counting, Sam reverses the ritual used to summon him, banishing him and the other fairies.
5. A human-like fairy named Gilda is controlled by Gerry. It is unclear what type of fairy she is, all she says about herself is that she's a good fairy. Under the control of Gerry, she injures several of his rivals in a LARPing game and kills two before Charlie Bradbury destroys Gerry's spellbook and sets her free.
One origin story for Changelings is that they are fairies from Western European folklore.
The brothers originally attribute the disappearances of four men to UFOs. After Dean is abducted and escapes, Sam deduces that they are dealing with fairies. They go to speak with Marion, who appears knowledgeable on the subject. She tells Sam and Dean that fairies include "sprites and spriggans, boggarts and brownies" as well as elves, gnomes, and trolls. She says these creatures come from some sort of parallel universe. They are vulnerable to Iron and Silver. If someone pours salt or sugar in front of them they have to stop to count the grains.
They discover that the fairies were summoned by Mr. Brennan using a book he inherited from his grandmother. He made a deal with the Leprechaun, who agreed that the fairies would work in his shop in exchange for the "fruit and fat of the land." The fairies then proceeded to steal his and other firstborn sons in Elwood.
Mr. Brennan tries to reverse the spell that summoned the fairies, but the Leprechaun kills him before he can finish. The Leprechaun seems to be very powerful, employing what he calls "real magic." He also claims that he can do what angels cannot and tries to make a deal with Sam for the return of his soul from Lucifer's Cage.
Sam refuses the deal and defeats the Leprechaun by emptying a container of salt in front of him. He is forced to sit down and count each grain while Sam reads the incantation that banishes him and all of the other fairies.
A good fairy named Gilda is put under a spell by Gerry who forces her to injure and later kill his rivals for Charlie Bradbury's heart. According to Gilda, she is unable to free herself from the spell and it can only be broken by a hero destroying Gerry's spellbook. Under Gerry's orders, she captures Charlie so he can "rescue" her and become a hero and while Gilda holds Charlie prisoner, Charlie becomes attracted to Gilda and kisses her. Sam, Dean and Gerry arrive and Gerry forces Gilda to use a suit of armor to pin down Sam while he tries to kill Dean with a sword he has Gilda transform to real. In the fight that follows, Dean knocks Gerry's spellbook from him and Charlie stabs it with a knife, destroying it and breaking the spell. Dean knocks out Gerry who Gilda takes back to her realm with her to face a fairy tribunal for his actions. Gilda and Charlie share a final kiss before Gilda leaves and Charlie hopefully calls after Gilda to call her.
Fairies in Lore
Fairies are mythical creatures, appearing in many forms. The lore (mostly Irish or Scottish) on them suggests that they are extremely diverse: the category of "fairy" includes goblins, gnomes, elves, and leprechauns. There are also popular beliefs that they are undead, elementals, ethereal creatures, or even fallen angels. Most fairies have strong magic powers.
Fairies also appear in folktales as pagan deities and seem to be similar to those the Celtic folklore calls "the hidden people."
