Supernatural’s Leviathans: Every Power, Ability, & Weaknesses They Possess

Every fan of Supernatural knows about Leviathans and most will agree they did not win over anyone’s heart. Leviathans or the “old ones” are the ancient monsters who God trapped in Purgatory until sweet, little, naive Castiel let them all out in season 7 in order to defeat Rapheal. While Death found them entertaining, no one else was a fan of the human-eating water beasts.

The Leviathans are the strongest and most destructive creatures, which is the reason God shut them away in the first place. The Old Ones definitely have their strengths, but they also have their weaknesses. Here are all of the Leviathans powers, abilities, and weaknesses:

10 Power: Supernatural Senses & Concealment

Leviathans are like bloodhounds on overdrive. These ancient beings have incredible senses that are far superior to humans as they can sense when angels and demons are around, which helps them out when they need to conceal themselves from said angels and demons. Edgar was able to sense angels, and so he concealed himself from them.

This power made it possible for Edgar to sneak up on the angels and kill them. Every species relies on its senses, and if one creature has enhanced senses though it quickly places them at the top of the food chain.

9 Weakness: Hunger

Leviathans may be the superior creatures but even they have an Achilles heel and that’s hunger. Leviathans’ unbearable hunger is what got them thrown into Purgatory in the first place as God feared they would “chomp the entire petri dish.”

Leviathans are so driven by their hunger that they are willing to turn to cannibalism if they must, and they can even chomp down on themselves, which is a punishment known as bibbing. While the Leviathans are on Earth, it is their sole mission to harvest humans for food, concocting all sorts of experiments to create the perfect human species for food. So if a Leviathan ever invites you over for lunch, say no.

8 Power: Invulnerability

Even the toughest of monsters would be stopped in their tracks if a car fell on them or if they were injected with acid. And most monsters would not want to go toe to toe with an angel. But none of these things seem to faze Leviathans. Leviathans have the power of invulnerability, which means nothing really hurts them, not even a gunshot wound to the head or angel magic.

Leviathans are able to nullify angel magic and can quickly heal from any physical wound. Decapitation doesn’t even really affect them unless their head is kept far away from the rest of their body. Talk about thick skin.

7 Ability: Possession & Shapeshifting

Leviathans’ true forms are very unflattering as they are just a pile of black goo. Luckily for the Old Ones, they are able to possess others and shapeshift fairly easily. Leviathans are experts at possession as they can possess humans with a simple touch. The Old Ones are able to make it a permanent possession as they change the biology of the host. And many of them can share an already occupied host at the same time like when they possessed Castiel.

Leviathans are master shapeshifters as well as they are able to morph into someone else by coming into contact with a single strand of DNA. Leviathans can shift into more than just humans though. They can also shapeshift into other monsters like vampires. They are such pros at becoming someone else they can even mimic clothing and voices.

6 Ability: Superhuman Abilities

Most fans were amazed at how strong angels and demons are but these deities were put to shame when fans discovered Leviathans. Not only do Leviathans possess superhuman strength, speed, stamina, and agility, they also have superhuman intelligence. Leviathans are able to easily take down angels and their prey with their strength, agility, and speed.

They can withstand more than any other creature and never tire with their relentless stamina. But their high intelligence is where they really show how much of superior being they are. They were able to cure cancer, AIDS, and other human ailments. Superman has nothing on these ancient beings as they can fly too.

5 Weakness: Strict Hierarchy

Most societies need some sort of hierarchy in place to thrive and Leviathans are no different. The Winchesters were informed by prophet Kevin Tran that if they were to cut off the head, the body would flounder, meaning Leviathans would be unable to survive without their leader, Dick Roman.

Luckily for the Winchesters, angels, demons, and all of humanity, this was an accurate statement. When Dean was able to successfully kill Dick Roman, the rest of the Leviathans went into complete disorganized chaos. They were only able to thrive if someone was giving them instructions, maybe high intelligence isn’t a power of theirs after all since they apparently can’t really think for themselves.

4 Weakness: Bone of Righteous Mortal Washed in the Three Bloods of the Fallen

For the most part, Leviathans are considered immortal creatures, but they are not truly immortal as there is a way to kill them permanently. It’s a very specific way, but it will get the job done. In order to kill a Leviathan, one must have a bone of a righteous mortal, such as Sister Mary Constant who is as good and light as Leviathans are dark, that is washed in the blood of the three fallen.

The three fallen include Castiel as he is a fallen angel, Crowley, who is the ruler of fallen humanity, and an Alpha vampire who is the father of fallen beasts. Dean was able to kill the leader of the Leviathans with this very particular weapon. Good riddance to Dick Roman.

3 Power: Serpent Like Traits

Leviathans use to be sea creatures that were able to evolve to survive on land, but it seems they have more in common with a slippery serpent than with a fish. Leviathans are not only venomous like certain snakes, but they also have powerful jaws that can expand to be the size of their whole head.

If Leviathans don’t kill you with their venomous black oozing blood, then they will definitely take you down by taking a chunk out of you with their razor-sharp teeth lined mouth. These ancient beasts aren’t little tadpoles anymore.

2 Weakness: God

The Leviathans have proven themselves to be the top of the food chain as they are much more powerful and smarter than any other mortal being. But there is one immortal being who the Leviathans cannot compete with, and that is their creator, God.

God proved to be able to overpower his creations when he locked them away in Purgatory. Even though the Leviathans are intelligent and dominant creatures, they were unable to get out of the prison God sealed them in on their own. So even though Leviathans like to act like they are top dogs, even they got put in timeout by their creator.

1 Weakness: Borax & Witchcraft

There are two things that can slow down a Leviathan, and these are two very different types of concoctions. One way to slow down a Leviathan is by using a spell like Donald did in season 7, episode 5, when he was able to knock a Leviathan unconscious with one his spells.

But if you don’t have any spells or hexes handy, borax will do just fine. Sodium borate or borax is used in many detergents and cosmetics. Not only is it great for cleaning, but it also does the trick when you are trying to burn the flesh of a Leviathan so you can make your escape. Plan A is witchcraft, and Plan B is borax.
