Monster

Monster is the collective name given to the children and descendants of Eve. Although refering to many different species, they all share a point of origin, and many share traits. They are supernatural creatures with extraordinary strength and powers, and commonly prey upon Humans. When they die, their souls are sent neither to Heaven nor Hell, but to Purgatory.

Elite monsters
These monsters are of the strongest type, either by being physically stronger than the rest (like with Dragons), or are so unique that it's hard for hunters to hunt.


 * Dragons
 * Jefferson Starships
 * Phoenix
 * Shojo

High-tier Monsters
These monsters are stronger than the majority of monsters, but not among the strongest.


 * Arachne
 * Djinn
 * Shtriga
 * Vampire
 * Wendigo
 * Werewolf

Medium-tier Monsters
These monsters are about average in terms of strength and powers. They are also normally harder to kill than the Lower-tier monsters.


 * Crocotta
 * Khan Worm
 * Rakshasa
 * Rugaru
 * Siren
 * Skinwalker
 * Vetala
 * Wraith

Lower-tier Monsters
These monsters are considered the easiest to kill, and possess the weakest powers. Despite this, they are still dangerous to hunters.


 * Changeling
 * Ghoul
 * Kitsune
 * Okami
 * Rawhead
 * Shapeshifter

Unknown Ranking
These are monsters, who haven't actually appeared (yet), so their placement on this list is unknown.
 * Gorilla-Wolves (Mentioned by Dean)
 * Chupacabra (Mentioned by Gordon)
 * Loch Ness Monster (Mentioned by Bobby)
 * Lamia (Hunted by Sam and Dean, but never physically appeared in the episode)
 * Dr. Visyak (As the only of her kind ever seen, and nothing was revealed about them, its unknown what type of monster she is)
 * Gorgon (mentioned by Sam)
 * Minotaur (mentioned by Sam)

Alphas

 * See: Alphas

Alphas are the first of each monster, and the direct descendants of Eve. As a result, each one is more powerful than any other member of their species. They are the creators of the rest of their species, and as such are the undisputed leaders of their kind.

Packs
Although many monsters are solitary, some, particularly the intelligent ones, form groups or packs, where they live and hunt together in "nests" or packs. Pack leaders serve as the bosses of these groups. This is not always a definite rule however, as some monsters known to live in packs, do sometimes live on their own as well.

Monsters also sometimes live in family groups, ones such as Changelings do this, in which case the parent leads them.

Monsters known to live in Packs

 * Djinn
 * Dragons
 * Ghouls
 * Jefferson Starships
 * Skinwalkers
 * Vampires
 * Vetala

Known Pack Leaders
Vampire:
 * Luther - This leader governed a small pack of Vampires.
 * Boris - He commanded a group that recruited/created new vampires.
 * Lenore - She commanded a pack of vampires that fed on animal blood instead of human until Eve's influence pushed them back to feeding on human blood.
 * Dixon - Created a pack to make new "daughters" after his own daughter was killed by hunters.
 * Old Man - Led a pack of vampire pirates. Was so old he thought himself a god and forced his men to worship him as one.
 * Desmond - Rogue vampire who wanted to create his own pack and tried to get Benny Lafitte to help him.

Skinwalker:
 * Unnamed Pack leader - A certain High-tier leader of some Skinwalkers.

Becoming a monster
Monsters are made in a great variety of ways. While this is not a complete list, it shows some of the more common methods of monster reproduction.

The orginal and most effective method is by tactile contact with Eve, the mother of all. She had the ability to turn humans into monsters or hybrids with a mere touch. This is presumably how most Alpha's were created.

The most common method, is however simply be sexual reproduction between monsters, which Changelings, Djinn's, Kitsune, Ghouls, Vetala and presumably all other monsters, whose method hasn't been stated do.
 * By Biting - Werewolves, Skinwalkers and Jefferson Starships can pass on their curse by biting a human.
 * By Genetics - Some monsters reproduce genetically without having to turn or infect humans. This is not the same as sexual reproduction between monsters, as In these cases their monstrous nature remains dormant for years, making them appear completely human before it emerges. Rugarus, and Shapeshifters reproduce in this way.
 * By Transfusion - Introduction and admixture of Vampire blood with a human's blood turns humans into vampires.
 * By Ingestion - A significant amount of vampire blood taken orally by a human causes him or her to turn into a vampire
 * By Venom - The Venom of an Arachne can turn its victim into an Arachne.
 * By Eating Human Flesh - Succumbing to cannibalism for long enough will turn a man into a Wendigo.

Common Attributes
Many monsters share traits and attributes:
 * Feeding on Humans - Most, if not all, monsters feed on humans - either human flesh, blood, certain organs, souls or all four. Only Shojos, Sirens, and Phoenixes don't seem to eat humans, they just kill them outright. Shapeshifters have never been seen eating people, or having any intent to, however it was implied by the Leviathan Edgar that at least some of them did. Some Monsters also have certain preferences in types of humans, Dragons eat Virgins, Rawhead's eat children, Okami each eat a certain type of human, down to preference, young Changeling feed on mothers, while older ones eat children, Shtriga normally feed on children as well.
 * Non-human Eyes - Shapeshifters, Jefferson Starships, Werewolves, Kitsunes, Skinwalkers, Wendigos, Vetalas, Dragons, Rugarus, Djinns, and Rakshasa can all be identified by their strange or unusual eyes, though some require certain conditions to be noticed (such as a Shapeshifter's eyes flashing yellow when seen through a camera).
 * Claws - Werewolves, Shojos, Kitsune, Skinwalkers (in dog form), Wendigos, Dragons, Rawheads and Lamia, all have razor sharp claws.
 * Fangs - Vampires, Werewolves, Okami, Jefferson Starships, Wendigos, Skinwalkers, Crocottas, and Vetala possess monstrous fangs. Vampires and Vetala use them to suck the blood of their victims, for others they are used to tear and devour flesh.
 * Superhuman Strength - All monsters typically possess some degree of superhuman strength, ranging from just stronger than humans, to being able to lift a man with one hand or snap steel chains, with the possible exception of Sirens. Dragons, Werewolves, Shojos, Rugarus, Vampires, Jefferson Starships and Wendigos are among the strongest of all monsters.
 * Superhuman Speed - Many monsters are much faster than humans so they can sneak up on humans unnoticed or outrun them in a chase. Skinwalkers, Rugarus, Werewolves, Vampires, Kitsunes, Jefferson Starships, Djinn, Crocotta, Dragons (while flying), and Wendigos possess these powers but Wendigos are the fastest of all monsters.
 * Shapeshifting - A common power of many monsters is the ability to change their form. Some, such as Shapeshifters, Sirens, Rakshasa, and Jefferson Starships, can change into whatever they want, while others are more limited. Dragons, Crocotta, Changelings, Shtriga, Phoenixes, Kitsune, Skinwalkers and Djinns can only change between their true form and a human disguise. Some monsters have certain requirements or limitations to their transformations, such as Werewolves, the only monsters that can't control their ability to transform (however, pure blood werewolves can shape shift at will,) or Ghouls, which are able to change into anyone, but only if they eat the person's flesh.

Weaknesses
Although there is no universal weakness that applies to all monsters, many share weaknesses:
 * Beheading - Vampires, Ghouls and Arachne can be killed by having their heads removed (as can Shapeshifters). This is also how Jefferson Starships are killed. This might work on most, if not all, monsters.
 * Fire - Many monsters on supernatural have shown that they are vulnerable to and can be killed by fire. These monster are Wendigos, Lamias (with certain herbs), Changelings, and Rugarus.
 * Mirrors - Changelings, Sirens and Wraiths all have their true forms revealed by mirrors.
 * Silver - Several monsters are vulnerable to silver, the most well known are: Werewolves, Skinwalkers, Vetala's and Shapeshifters. Silver is also part of the thing needed to kill both Djinns and Lamias. Wraiths are vulnerable to silver, to touch it will burn their skin.
 * Vamp-Tonite - As well as dumbing down humans, a side effect of the Leviathan Corn Syrup additive, is it makes the blood toxic to any non-Leviathan monster (Vampires, Werewolves, Ghouls, Shapeshifters etc) who drink it. This is to wipe out the monsters, so that the Leviathans don't have to compete for food resources.
