Eve

In some way related to Leviathan, Eve was a being known by the title of Mother of All. She was cast into the deepest bowels of Purgatory, until she was released by dragons, arrived on Earth, using a young virgin girl as a vessel. She was part of existence before angels were, which gave her an advantage over them, being able to inhibit them from using their supernatural powers.

Eve created the Alphas, which were the first monsters of their allotted kind from who their species descended. She created a worm-like creature, which Dean dubbed the "Khan Worm". She also just did what she called "Beta testing" and created creatures that Dean named "Jefferson Starships", which were monster hybrids that she mass produced. Her only known weakness was that of Phoenix ash. She was killed by Dean, who mixed the ashes in his drink earlier, and when she bit him to turn him into a monster, she ingested the ashes and died.

Physical Appearance
Eve's true appearance was not known; however, a glimpse of it on a video camera revealed a gray, withered, somewhat shadowed face. In her introduction, her eyes glowed a fiery yellow-orange, but in the said recording they were milky-white, similar to Lilith's. Upon her death, her veins darkened and she bled watery black blood.

When Eve manifested on Earth in Like A Virgin, she possessed the body of an attractive brunette girl wearing a white dress whom two dragons offered up to her as tribute. In her last episode, she briefly took on the form of Mary Winchester.

Personality
Like Death, Eve was normally content to uphold the natural order in which monsters and humans killed each other in turn; however, when Crowley began capturing, torturing, and killing her children in droves during Season 6, she decided to turn every human into a monster to deprive him of the power of any souls. She exhibited few emotions beyond serenity, but her decision to pose as a waitress merely to surprise Dean and Sam suggests that she had a sense of humor. She seemed to be upfront and honest when speaking with the Winchesters. She also had a mocking side to her sense of humor as she took their mother's form to taunt them.

Eve was largely apathetic towards the human race as a whole, but occasionally showed disdain or cruel amusement towards them. She began compelling even her benevolent children, such as Lenore, to kill or turn as many as possible against their will once she arrived on Earth, presumably to build her army. In Mommy Dearest, she went about trapping a bar filled with people, infecting some, and allowing the others to be killed while she watched on and casually sipped at a drink. However, she was initially willing to negotiate with the Winchesters if they agreed to help her capture Crowley.

When explaining what she had done to someone she had turned, Eve simply called her infection "a gift". She viewed herself as a loving mother with regards to all monsters descended from her. She was angered by Crowley's barbaric attempts to use her children to find Purgatory, and arranged to be summoned onto Earth in order to stop him. She also seems to detest God, and seems disgusted that he would abandon his children, something she claims she would never do.

Powers and Abilities
Eve was an incredibly old and powerful entity, stronger than any monster, demon, or even angel. It is unknown if she was stronger than Leviathans and Archangels. Despite this, she remains the most powerful female character/antagonist in-series to date. The only beings known to be surely more powerful than Eve is God and Death.

Eve was also one of the very few entities capable of creating new beings. She also possessed the ability to alter the human soul, a trait she passed on to all of her children. Eve also referred to the souls in Purgatory as her 'supply', implying she could draw on souls for power, not unlike angels and demons.


 * Immortality - Eve is immortal and cannot die of disease or old age. She referred to herself as being older than even the angels. 
 * Invulnerability - Conventional weapons and most mystic ones don't have any effect on Eve. The only known thing that can kill her is Phoenix ashes, either by oral ingestion, being injected with it or being shot with shotgun shells filled with the ashes.
 * Flight - Once she took her vessel, she rose from Purgatory.
 * Possession - In order to manifest on Earth, Eve required the use a vessel, and that vessel had to be a virgin girl.
 * EveandDean_6x19.jpgConjuration - She could turn humans into whatever she desired, through physical contact, either a touch, a kiss or a bite; this is how she created her first children. Apparently, she did not have full control over this ability, seeing as as how a number of her creations in "Mommy Dearest" died prematurely before she eventually succeeded in creating "the perfect monster", she dismissed these failures as "beta tests".
 * Regeneration - When she rose from Purgatory, Eve's arms and legs were covered in severe burns, however she later reappeared completely restored.
 * Super Strength - Her strength was far superior to humans and every Earthly supernatural creature. She was confident enough to claim that she would take care of the demon Crowley if she was to find him. Humans were no threat to her in terms of bodily force.
 * Super Speed - She could move at undetectable speeds for a human being.
 * Teleportation - She could reappear in different locations at will.
 * Shapeshifting - At one point, she modified her vessel's appearance to look and sound like Mary Winchester. Her shapeshifting was advanced to a degree seen only on few other creatures--the Alpha Shapeshifter, the Leviathan and the Archangels.
 * Telepathy - She was psychically linked to all monsters, allowing her to know what they do and speak to them through their minds and could communicate with her children even while imprisoned in Purgatory. According to her statements in "Mommy Dearest", she was aware of the hunters' arrival and intent to kill her before they met, and perceived Crowley torturing her children as though she were his victim instead. She could also read a human's mind, as she was capable of shapeshifting into Sam and Dean's mother despite never having seen her.
 * Compulsion - Using her mental link to her children, Eve could control the various monster lines and instill bloodlust in them, even over great distances, as seen when she compelled her many children (even the more benevolent ones like Lenore) to attack and turn as many humans as they could.
 * Supernatural Senses - She possessed heightened senses. She managed to realize Dean and Sam were using Phoenix ashes by simply smelling the barrels of their shotguns.
 * Angelic Power Negation - Due to her advanced age and knowledge, Eve was able to block an angel from accessing their powers by "unplugging them" as shown when she negated Castiel's abilities through her mere presence. Her overall knowledge over angels was extensive and she knew how to conceal herself from them.

Weaknesses

 * Phoenix ash-Phoenix ash is the only known thing that is known to be able to kill Eve.

Early life
Eve predated angels, which would dictate that she also existed before the creation of Earth and humanity. She was related to the leviathans in some way and even knew some of them. She created the Alphas, which were the first monsters of their allotted species. Eve had been on Earth ten thousand years ago. Afterwards, she returned or was cast back to Purgatory, where the souls of her children go after death.

Season 6
Crowley and Castiel began working together in order to find Purgatory and use the souls within as power; to this end, they needed to interrogate Eve for information. Crowley tortured and slaughtered many monsters in an attempt to lure her to Earth.

Eventually, Crowley's gambit worked; an angered Eve ordered the Alphas to amass an army and arranged for her release with dragons, who abducted virginal women and used one as a sacrifice to summon her in "Like A Virgin". She created new breeds of monsters, known colloquially as "Khan Worm" and "Jefferson Starships", in attempt to create a new, "perfect" monster which she planned to infect the entire human race so that Crowley would be denied any souls. Several of her early experiments result in failure as the creatures died prematurely. However, in "Mommy Dearest" she managed to succeed in Ryan Silver, an orphan boy whom the Winchesters "rescue"; Ryan later converted his brother and both attacked their uncle.

With Bobby Singer and Castiel waiting outside, the Winchesters entered the diner in which Eve was hiding and discovered that they were surrounded by hybrids and Eve herself. She took their weapons and detected phoenix ash in the shotguns, so she handed them over to one of her children and ordered their immediate destruction.

Eve explained to the brothers the reason why she came to Earth and what she hoped to achieve; to emphasize her point, she transformed into the likeness of their deceased mother. Dean claimed that her arrival was pointless, as they believed that Crowley had already been killed months before, but she revealed that Crowley was indeed still alive and searching for Purgatory.

Eve also informed them of the "perfect monster" she had created in Ryan Silver and of the mass-infection that they inadvertently helped spread. Her children then brought Castiel and Bobby into the diner.

Eve offered Sam and Dean the chance to work for her in capturing Crowley. Dean refused to work with a monster, however, and told her "bite me". She obliged, deciding to force them to obey her anyway by making them into her children, but was poisoned by phoenix ash in his blood, as he had ingested it with a shot of whiskey.

Eve choked and burned from the inside before falling to the floor, dead. At once her children attacked the group, but with Eve no longer suppressing Castiel's powers, he effortlessly slew all the remaining monsters in the diner. He took the hunters to stop the Silvers, only to discover that demons sent by Crowley had already killed them.

Afterwards, Crowley recovered Eve's body and performed an autopsy. He was upset with Castiel for having allowed Dean to kill her, as they had lost their best chance on opening Purgatory.
