Summary

  • The Changeling is a supernatural being that replaces stolen children. They are stronger than humans but can be beaten by fire or by eliminating the Changeling mother.
  • Ghosts and poltergeists are different types of supernatural entities. Ghosts are spirits of the deceased while poltergeists want attention and can be dangerous. A special ritual or salting is needed to eliminate poltergeists.
  • The Rugaru is a tragic supernatural creature that transforms into a monster with animal instincts at the age of 30. It can be defeated with fire or enchanted weapons.

The most powerful Supernatural creatures were part of the overall mythology of the Winchester brothers' battle against angels and demons, Heaven and Hell, with Earth and humans caught in the middle. However, much like The X-Files before it, the show might be the most fun when it takes on the Monster of the Week episodes. Sam and Dean Winchester were hunters, battling all kinds of supernatural monsters and demons to save lives and protect the innocent. The entire premise from the start was that the boys were hunters and the supernatural creatures they hunted ranged from the classic myths to some really evil and powerful original creations.

Supernatural ended after 15 seasons, with Dean and Sam finishing their mission, Jack overtaking God for the power of Heaven, and many of the most powerful Supernatural monsters falling along the way. However, 2022 also saw a new chapter in Supernatural lore with The Winchesters, a prequel series that showed how Dean and Sam's parents met and became great hunters in their own rights. This re-painted many of the myths fans knew from Supernatural in a new light. However, they rarely matched the memorability of the most powerful Supernatural monsters from the original series.

Changelings

Season 3, Episode 2

A Changeling in the backseat in Supernatural.

The Changeling is a supernatural being from European mythology, and they are monsters that replace a stolen child. In their natural state, they are discolored with hollow eyes and a rounded mouth, which is full of teeth. They look human unless seen through their reflection. The Changeling mother feeds on the stolen babies while the young Changelings feed on the mothers. While what happens to the stolen babies is tragic, Changelings are not as powerful as other Supernatural monsters. They are stronger than humans, but they can be beaten by fire as well as by eliminating the Changeling mother. They never appeared again after season 3.

Ghosts / Poltergeists

Recurring Since Season 1

Kevin Tran becomes a ghost in Supernatural.

When it comes to Supernatural, ghosts and poltergeists can get pretty confusing. In many instances, they are just lumped together, but there is a difference between the two. Ghosts are the spirits of the deceased who were unable to move on to Heaven or Hell and are stuck on Earth. They are not always bad and sometimes work to help humans in times of need. Meanwhile, Poltergeists are extremely dangerous. Unlike ghosts, which are simply stuck on Earth -- and in many cases want to move on -- poltergeists want attention and will do anything to receive it. They are former ghosts who are now powerful creatures. It takes a special ritual or salting to eliminate them.

Crocotta

Season 3, Episode 14

The Crocotta sucking out Stewie's soul in Supernatural.

A Crocotta is a supernatural monster that is dangerous because it can mimic a human's voice. It can use the voices of loved ones to lure victims into traps that it has set up. They are based on a mythological monster from India. According to legend, they were animal-like creatures that could mimic human speech and then attack and eat their victims. The interesting alteration to the Supernatural monsters is that they developed the ability to use telephones and computers, which creates an easy way of obtaining victims, as they no longer need to hunt. They eat their victims and devour their souls. However, a Hunter can beat them by stabbing them in the back of the neck.

Rugaru

First Appearance - Season 4, Episode 4

A rugaru on the hunt in Supernatural.

The Rugaru is not only a powerful supernatural creature, but they also have a tragic history as well. These are normal humans who live a normal life until they hit the age of 30. However, when they turn 30, they morph and change into a monster with animal instincts that make them hungry. Because of this, they will eat anything -- even former loved ones -- since they are unable to control themselves. No Rugaru was able to avoid their fate no matter how good or virtuous the person was, since they fell victim to the curse on their 30th birthday. Fire is one of the few things that can take a Rugaru down, besides a few enchanted weapons.

Sirens

Season 4, Episode 14

A siren luring in a victim in Supernatural.

The legend of the Sirens goes back to Greek mythology, where the monstrous women would sing enticing songs and lure sailors to their doom. When it comes to Supernatural, the legend was brought to land, where these beings now use their voices to lure people to their end. On the show, they are not beautiful in their natural state, as they are hairless and barely human-looking. However, they are shape-changers and can look like whatever their victim most desires in order to lure them in. They can then tempt them to betray their loved ones. It takes a Bronze Dagger coated in the blood of their victim to defeat a Siren.

Soul Eaters

Season 11, Episode 16

Soul Eaters closing in on Supernatural.

Soul Eaters are ancient supernatural creatures that live in another dimension. They feed on human souls after they drag them from the physical world into their nests. Once the souls are dragged there, they are trapped forever and remain there even if their body perishes. The problem here is that for the longest time, hunters believed that Soul Eaters couldn't perish. It took a Celtic Sigil to entrap them. However, the British Men of Letters learned that placing the Sigil in the nest could turn the Soul Eater to dust and set the victims' souls free.

Wendigo

Season 1, Episode 2

A Wendigo in the shadows in Supernatural.

One of the earliest Supernatural monsters introduced was the Wendigo, which was the monster that Sam and Dean Winchester had to defeat in the second episode of the series. They come from the Algonquian mythology and are cannibalistic creatures that can possess humans. They also possess super speed and are immortal. These are some of the most difficult creatures to eliminate. It takes fire to end the life of a Wendigo. The problem is that they are very fast, very smart, and avoid the heat. Anasazi symbols can keep them at bay and protect individuals from becoming prey.

The Scarecrow

Season 1, Episode 11

The Scarecrow in the field in Supernatural.

The Scarecrow was a Supernatural monster that appeared in season 1 in an episode of the same name. As expected, this is a living scarecrow in a field that takes its victims by luring them from the road. The Scarecrow also seemed unbeatable, as Dean's gun had no effect on it. The Scarecrow turned out to be a manifestation of the Norse God Vanir. The townspeople sacrificed strangers to it in order to keep their community "blessed." The only way to destroy this monster is to burn the sacred tree that gave it power.

Rakshasa

Season 2, Episode 2

The Rakshasa standing by a truck in Supernatural.

For everyone who hates clowns, the Rakshasa can be pretty scary. These are Hindu creatures that feed a few times every 20 to 30 years. If its appearance isn't obvious enough, this monster is also probably a reference to Stephen King's Pennywise in It. These are creatures that eat human flesh, sleep on deceased insects, and can shapeshift to appear as humans -- mostly clowns. They have superhuman strength and speed. They can also become invisible. However, they can't enter a home without an invitation. They are invulnerable to everything except brass.

Daeva

Season 1, Episode 16

The Daeva shadows in Supernatural.

The Daeva is a savage and animalistic demon that appeared in the first season of Supernatural. The one thing that holds back the Daeva is that they have to be summoned or conjured. However, they will attack the person who summons them as well as the target they are sent after. They are invisible, but their shadows are not. Mostly, they are used as tools by powerful demons in order to take out their enemies. They can teleport and have super strength, as well as dangerous claws. Since they are demons, they won't perish, but light can repel them and black magic can control them.

Shtriga

Season 1, Episode 18

The Shtriga attacking in Supernatural.

The Shtriga is based on an Albanian myth that dates all the way back to Ancient Rome. They are similar to witches but, instead, Shtriga feed on a person's Spiritus vitae, which is their life force. Once a person loses this, their immune system weakens. In Supernatural, they mostly feed off children's lifeforce. While Sam said that the Shtriga are invulnerable to all weapons made by men and God, this was not entirely true. If caught feeding on someone, they are vulnerable to consecrated iron, and while it won't end them, it will cause them to flee.

Witches

Recurring Since Season 1

The witches casting a spell in Supernatural.

The witches on Supernatural are pretty much the same type of witches that we see on other horror TV shows, movies, and books. They cast spells by connecting to supernatural forces and can communicate with spirits. As Sam said in "Malleus Maleficarum," what makes them dangerous is that they can be anyone, and it is impossible to know who is and isn't a witch. The power of a witch is dependent on both their source of magic and their knowledge and training. Rowena is a perfect example of an extremely powerful witch, a Supernatural villain that the fans loved. The main weakness of most witches on Supernatural is iron.

Ghouls

Season 4, Episode 19

Ghouls closing in on their victim in Supernatural.

Ghouls are Alpha-level supernatural monsters that feed on the flesh of the deceased. After this, they take the form of their victim and then seek out their next target. There are also times when ghouls will feed on the living, and they can take on the forms of their victims even if the victim is still alive. They can also change back to a former form if they desire. They have super speed, strength, agility, and senses -- all higher than normal humans. They are also indestructible, though they can be decapitated and are weak to brain damage. Ghouls might be a type of Djinn, but they are not that powerful.

Arachne

Season 6, Episode 13

The Arachne hunting in Supernatural.

As their name suggests, Arachnes are spider-based Supernatural monsters, although they take the form of a human. They can create strong webs like spiders to trap their victims. They can also turn a human into an Arachne by biting them, and they possess poison that can end a human's life with a single bite. They are similar to Spider-Man and possess the powers of a spider, including strength, agility, speed, and super senses. They are also vulnerable to most weapons and fire, but one sure way to end them is by chopping off their heads.

Werewolves

First Appearance, Season 2, Episode 27

A man turning into a werewolf in Supernatural.

Werewolves in Supernatural are exactly what most fans of horror fiction expect. They are relatives of skinwalkers and can morph into a human-wolf hybrid. They are carnivores and many eat humans. Most legends are correct, as they can turn humans into werewolves with one bite. However, in Supernatural, they can also sire werewolf babies. The most powerful werewolves are purebloods, which are close to the Alpha level. They can transform at will and can control their animal side better than regular werewolves. Silver and decapitation are two of the only ways to eliminate a werewolf.

Djinn

First Appearance, Season 2, Episode 20

The Djinn attacking Dean in Supernatural.

A Djinn is a creature that many commonly refer to as a genie. However, while many people see genies as beings that grant wishes, the Djinn is a sinister creature that uses trickery and deceit to gain their means. Unlike the typical legends, Supernatural changed these from supernatural beings into monsters. The Djinn on the series can touch a person and cause them to relive their deepest dreams and desires. This puts the human in a coma-like state, which allows the Djinn to feed on them. The only way a hunter can eliminate a Djinn is supposed to be with a silver knife dipped in lamb's blood, although Sam took one out by hitting its head with a golf club.

Jefferson Starships

Season 6, Episode 19

The Jefferson Starships attacking in Supernatural.

Obviously, this is a Supernatural creature that was named by classic rock-loving Dean Winchester rather than one that came from traditional mythological lore. According to Dean, he named them Jefferson Starships because they are "horrible" and hard to eliminate. Eve created these creatures as hybrid Supernatural monsters. These beings are considered the ultimate monster by Eve, since they have the characteristics of many of her previous creations, including the teeth of a vampire, the spike of a wraith, and the ability to shapeshift. While decapitation worked to slow them down, it took Crowley's demonic forces to finally eliminate them.

Hellhounds

First Appearance, Season 2, Episode 8

The Hellhounds claim a victim in Supernatural.

Hellhounds are extremely dangerous supernatural monsters that Sam has described as demonic pit bulls. They mostly serve demons from Hell and are a danger to humans, angels, and other demons alike. A Hellhound's main purpose is to collect the souls of humans when their deals with demons are due. Only those humans can see them in most cases. Once a Hellhound gets the scent of its target, it has it for life. The only way to stop a Hellhound is with iron, Angel Blades, The Colt, or with Ruby's knife. Salt can be used to block them out, but it will not stop them from finding a way to get to their prey.

Vampires

Recurring Since Season 1

A vampire howling in Supernatural.

Supernatural has worked hard to make their vampires very dangerous. Because of this, they eliminated most of the lore that classic movie monster Supernatural fans have grown accustomed to. The crosses don't affect vampires and sunlight does little damage. Even a wooden stake to the heart won't stop these supernatural creatures. However, like classic vampires, they are immortal, never age, have superhuman strength and speed, and are invulnerable to conventional weapons. They can also retract their fangs, which means that they can blend in with humans. For years, decapitation was the only way to eliminate them until the British Men of Letters came up with specially built weapons that turned their own blood toxic.

Khan Worm

Season 6, Episode 16

The Khan Worm on the floor in Supernatural.

The Khan Worm is another original Supernatural creature that Dean Winchester named. Of course, the name came from the classic Star Trek movie The Wrath of Khan due to their appearance and powers. Eve created these creatures, which can enter a human's head and then control their actions. The Khan Worm is extremely dangerous. It possessed Dean and caused him to end the life of his cousin Gwen Campbell. It then possessed Bobby Singer and forced him to take out his old partner Rufus Turner. These can be electrocuted while they're still in a host's body and can also be crushed if the worm escapes from the body.
