History

Demons were once human, their souls having been corrupted and warped after spending hundreds of years in Hell being tortured and having all of their humanity burnt out of them. they are left as large, black clouds that generate electromagnetic interference and leave behind a sulfurous residue. The first demon was Lilith. She was created by Lucifer, who resented humans for taking his place as the most beloved of god. Lucifer wanted to show how bad humans were, so tortured a human into becoming a demonic monster. He proceeded to do the same to any human souls he could trick into joining him. However, Lucifer was locked away by his own brother, the Archangel Michael, and Lilith was imprisoned deep within Hell. Thousands of years later, after much searching, Azazel, Lucifer's demonic "son", was able to find the doorway to Lucifer's prison. Lucifer revealed that only Lilith can break the 66 seals keeping him imprisoned, and instructed Azazel to find him "a very special child". Azazel spent the following years feeding his own blood to babies—one being Sam Winchester—as they would then grow up developing demonic abilities, including the ability to kill Lilith and hence free him from his prison, and then be powerful enough to serve as his earthly vessel.

Although an ordinary demon is featured as a villain of the week in the fourth episode of the series, Phantom Traveler, demons do not become actively involved in the show until the introduction of Azazel's "daughter"—possessing a girl named Meg Masters—in the second half of the season. She follows Sam and Dean Winchester, and later unsuccessfully sets a trap for them using their father.

Weakness

Salt- Demons are unable to cross a line of salt. Salt can also be used to torture demons if the salt is poured into the demons mouth the salt will cause great pain.It can be put into shotgun rounds to hurt and knock back demons.

Holy Water- Holy Water burns demons that come into contact with it like acid.

Iron- Demons can't touch or cross iron.

Ruby's Knife - The knife originally belonged to Ruby. It will kill a demon that is within a host if the host stabbed in a fatal place. Upper level demons are immuned to the killing effects of the knife. One such demon is Alistair.

The Colt- Much like Ruby's Knife it will kill any demon that is shot while within a host if shot in a fatal place.

Bones- If the bones belonging to the demon is burned the demon will be killed much like a vengeful spirit. This can also be used to torture demons. This until recently was believed to be merely a rumor.

Exorcism- Will pull the demon out of it's host and send them to hell. Hosts may not survive.

Devil's Trap- A Devil's Trap will hold a demon in place and prevent their escape. The Trap will also prevent a lower level demon from using their powers.

Angel's Touch- An angel can kill a demon by touching them on the forehead with their hand. This power will not work if the demon is upper level or if the angel is cut off from heaven.

Special Children- Sam Winchester developed special abilities almost especially tailored to hurt or kill demons. Due to training from Ruby and ingestion of demon blood he first developed the power to pull demons out of humans. Later the powers advanced to killing demons like the knife or colt. Although unknown it is assumed the other special children may have been able to do this if they survived, trained, and ingested demon blood.

Lucifer- He was able to kill demons easily with just a look.

Speculation

While most demons were once humans who were corrupted and turned into demons in hell. It is also speculated that some demons were angels who allied with Lucifer were punished for their betrayal by being exiled from heaven. They were sent to hell where they turned from angels to demons. If this is true then then it can be safely held that angels were not the original demons, Lilith was.

Another popular speculation is that Azazel is the son of Lucifer. This is believed by many of Azazel's claims.
