Crowley/Abilities and Weaknesses

Powers and Abilities
As the King of the Crossroads and later the King of Hell, Crowley is a very powerful demon, among one of the most powerful demons to appear in the series. This is perhaps best demonstrated by his single-handed slaughter of a nest of other demons off-screen in The Devil You Know (although he purposefully allowed one to escape). He ranks high in the hierarchy of Hell, at first presiding over other Crossroad Demons and serving as Lilith's right-hand man as the King of the Crossroads, then later becoming King of Hell. This title grants him much more power than he had previously.
 * Immortality - Crowley has an infinite lifespan and had the potential to live forever. He is not subject to disease or old age. At the time of his suicide, he was over 354 years old.
 * Supernatural Perception - Like all demons, Crowley can perceive Ghosts, Reapers, other Demons, and even Angels while humans cannot.
 * Super Strength - Being the King of the Crossroads and then later the King of Hell, Crowley is endowed with incredible superhuman strength. He can lift and press at least two tons and is stronger than humans, monsters, and average black-eyed demons; literally once taking on a hive of them simultaneously. Crowley also beat a demon on the head with a crowbar, whose head was in a bag that had a painting of a devil's trap. He also effortlessly and brutally beat Meg, a middle level demon. He also broke a steel door down with virtually no effort and then proceeded to lift Kevin Tran off the ground by the throat and would have strangled him to death if Metatron had not intervened.
 * Invulnerability - Crowley cannot be harmed or killed by conventional means. In "Caged Heat", he was hit over the head by Sam with a wrench and soon after Meg tortured Crowley by damaging his vessel's insides and making him cough up blood, but Crowley quickly recovered both times and he has not shown any signs of lingering pain or damage from either attack since.
 * Super Senses - Crowley was able to smell that Castiel had been in Dean's Impala and taste that the blood he and Raphael had been using was dog's blood.
 * Super Stamina - Crowley stated while torturing Samandriel that he can remain physically active infinitely. He has also stated that he does not need to eat or sleep.
 * Possession - Like all demons, Crowley requires a human host, living or deceased, to manifest himself on Earth. He has been known to possess five people besides Castiel: his usual vessel, Linda Tran, Sam, Andre Devlin and Marnie. He was also able to possess a rat.
 * Teleportation - Even before becoming King of Hell, Crowley could teleport himself and others over great distances with ease. He has proven to be quite proficient at this, as he was able to dodge Sam's knife attacks by teleporting rapidly. He can teleport between Earth and Hell with no difficulty at all. He can change his clothes in seconds, as shown when he teleports from a massage to Dean.
 * Apporting - He once caused an angel blade to teleport into his hand and teleported Delta and Kevin Tran to another location by snapping his fingers.
 * Telekinesis - As a demon, Crowley can move objects with his mind. He is shown to be very efficient at this, and has telekinetically pinned, thrown, and trapped humans. He was able to destroy a street light by pointing at it. He also broke a girl's neck without touching her and lifted another to a considerable height before using molecular combustion to bloodily obliterate her. Furthermore, he was able to throw Deputy Jenna Nickerson against a ceiling with enough force to kill her. Crowley also was able to thrust Amara across a room. Doing such a feat to the Darkness further displays his mastery of this power.
 * Electrokinesis - He switched off a television by snapping his fingers in "Weekend at Bobby's".
 * Pyrokinesis - Crowley can create and manipulate fire. He conjured a blazing fire in the fireplace in "The Devil You Know" by pointing at said fireplace, and conjured flames to burn a message into a table in "There Will Be Blood" before they extinguished themselves. He was also capable of engulfing himself in fire and create the illusion that he was burnt to ashes. He was able to extinguish a ring of holy fire by snapping his fingers and burn his mother's hex bag.
 * Thermokinesis - Crowley made a painful burn on Sam's hand with a touch in All Dogs Go To Heaven. He also made Ruby's knife burn red-hot with a snap of his fingers in We Need To Talk About Kevin to make Dean drop it. In Hell's Angel, Crowley was able to remotely scorch the words "Help Me" into the forehead of his vessel while fighting Lucifer inside of Castiel to get the Winchesters to save him. The effect didn't last long and by the time Crowley returned to his vessel, the words were gone.
 * Reality Warping (by deals) - As King of the Crossroads, Crowley is able to warp reality in the form of a deal to a greater extent than other crossroad demons and can even undo contracts made by other crossroad demons.
 * Resurrection (probably by deals) - Crowley has the power to resurrect the dead if a deal is made, as he promised to bring Mary back for Samuel if Samuel helped him find Purgatory. Contrary to Azazel's claims in All Hell Breaks Loose - Part 2, Crowley may also have the power to resurrect the dead without a deal due to being King of Hell, as he claimed in Family Matters that he was the one who brought Samuel and Sam back to life; although his supposed resurrection of Sam was proven untrue, it was implied in The Man Who Would Be King that he did indeed bring Samuel back. He also resurrected Lucifer's old vessel Nick in order to have him act as the archangel's vessel once more.
 * Healing - Through a deal, Crowley was able to heal Bobby Singer's paralysis. He later healed a small burn he caused on Sam's hand. Through a deal, Crowley healed Ellie's mother's Parkinson's disease.
 * Invisibility - He rendered himself unseen and unheard by Dean in the flashback of "The Man Who Would Be King" while he talked to Castiel in Dean's presence.
 * Voice Mimicry - He taunted the Winchesters by briefly imitating his usual vessel's voice while possessing Linda Tran.
 * Spell Casting - Being the son of a witch, Crowley has stated his mother had taught him a "few tricks". He has proved himself adept at Enochian warding magic. He also placed a spell that prevented creatures from escaping their vessels on an entire building in Caged Heat. He also learned the spell to bind Death in Meet the New Boss, which he passed onto Bobby and the Winchesters. He was also able to disguise his demons as Sam and Dean to fool Kevin Tran. In Clip Show he cast a spell to kill Sarah Blake with a hex bag hidden in a hotel room's cordless phone and previously caused Tommy Collins' head to explode using a spell. He also used this in an attempt to kill Jody Mills. He also used a spell to create an illusion that was powerful enough to trick Cain.
 * Biokinesis - He was able to cause a man to cough up blood. While killing Louis, he forced him to be unable to speak, begin convulsing, and forced him to face towards his mother before causing him to bloodily explode.
 * Molecular Combustion - Caused Krista to explode into a shower of blood, as well as Louis.
 * Terrakinesis (possibly) - Crowley may have the power to create tremors at a particular location. When he and his demons arrived at the church Kevin and the Winchesters were at in "We Need To Talk About Kevin", one of them caused the grounds to shake to announce their arrival.
 * Torturing - Crowley is shown to be skilled in torturing an individual, as seen when he tortured various monsters for the location of Purgatory or when he forced the names of the future prophets from the angel Samandriel. He is also skilled enough to break into an angel's factory settings.
 * Immunity - Crowley can walk on hallowed ground. Although he finds being shot with rocksalt painful, he is not significantly affected by it, indicating that he may be resistant to salt. He was also able to resist and destroy one of Rowena's Defigere Et Depurgare hex bags, which had caused a weaker demon to cough blood to deathin a matter of seconds upon touching her hexbag.
 * Regeneration - Despite being shot by Dean Winchester, Bobby Singer and Abaddon, Crowley seems to have healed his wounds as there is no sign of them in his other appearances. He was stabbed by Meg with an angel blade and while his shoulder was briefly injured, the wound easily healed after a short while. Also, while Metatron severely burned his host's skin with a burst of white light, Crowley's vessel healed completely. Oddly, when Crowley vacates his host, his burn injuries do not seem to reappear.
 * Mental Manipulation - Crowley was able to implant every word of the English language into his son, Gavin's, mind.
 * Memory Manipulation - Crowley states that he "scrubbed" Kevin's short term memory, but noted that it was risky and didn't want to have to perform it again.
 * Animal Communication - Crowley is able to understand and talk to animals.
 * Sedation - When Crowley went to confront and capture Oskar for the spell to remove the Mark of Cain, he was able to render every other person in the diner unconscious in the blink of an eye.
 * Dream Walking - In a deleted scene for Brother's Keeper on the season 10 DVD Crowley displayed this ability to visit Dean in his dreams.
