The Leviathans in Supernatural have a lot of powers and abilities, but they also have quite a few weaknesses.
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:
5/5 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.
4/5 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.
3/5 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.
2/5 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.
1/5 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.
