The Darkness/Abilities and Weaknesses

Powers and Abilities
"We are mightier than God."

- Amara, to her younger form

"Lucifer: Yeah, first time it took the combined strength of me and my brothers to weaken Amara before Daddy-O finished her off. God: Even then it was close. Now with just the two of us, we'll lose."

- Lucifer and God regarding Amara's power

The Darkness is the most powerful entity in existence. In several instances, God stated that even with all four archangels fighting against her the first time, along with himself, victory was barely achieved. Even Death, a primordial being nearly as old as her brother and his equal in strength, showed to be very fearful of her, as he refused to remove the Mark of Cain from Dean unless he shared it with someone else, lest Amara be freed. Her release prompted God to hide out in what he dubbed the "safest place ever created", so he could be safe from her. The Darkness was powerful enough for her mere release to damage Lucifer's Cage, a prison designed to imprison Archangels. Even after withstanding a combined but sequential attack by powerful supernatural beings (witches, every angel in Heaven, demons, and Lucifer), she still proved to be stronger than God when she stopped him from trapping her again, overpowered Lucifer at the same time, and fatally wounded her brother, all before regenerating fully and walking away. Not long after, upon reconciling with God, Amara was able to heal the fatal damage her nigh-omnipotent powers did to him, without any difficulty.
 * Immortality - The Darkness is immortal. Even the combined power of all the angels caused her no permanent harm. She was also unfazed by a Hand of God-empowered Lucifer. However it's been stated that she can die as she asked her brother God to kill her.
 * Nigh-Invulnerability - Considering her ability to stand against God and his archangels, the Darkness has immense resilience to physical and supernatural attacks. God himself was only able to speculate about what might be able to kill her.
 * Regeneration - Amara has shown a healing factor. When she was wounded by a massive angelic smite, she absorbed an Angel's grace and took help from Rowena in order to restore her powers. However, after being significantly weakened by a massive angelic smite, full scale demonic attack, Crowley attacking, and Lucifer's Spear, she regenerated only minutes afterward.
 * Superhuman Endurance - She has displayed significant tolerance for extreme physical and psychological trauma. This was seen when, despite the combined massive attacks from Rowena and other Witches, Demons, Angels and Lucifer, she was still able to move and walk up to God.
 * Nigh-Omnipotence - Castiel describes The Darkness' power level as near infinite, and she describes herself as more powerful than God. In fact, she is so powerful that her brother couldn't defeat her without the archangels, and their combined power was barely enough to seal her away, by tricking her first. Even weakened after a combined attack from witches, demons, angels, and Lucifer, she managed to overpower and fatally wound God, as well as overpower and rip Lucifer from Castiel's body. Amara states God even at full power isn't powerful enough to force her to do anything. Among the powers she showed were:
 * Absorption - The Darkness is able to absorb energy attacks as seen in O Brother, Where Art Thou? and Hell's Angel. She was able to absorb the combined smiting of all angels, although it weakened her to a certain degree. The attack was supposed to destroy a large area instead it only formed a crater. Later, she absorbed an attack from Lucifer with the Horn of Joshua, this time without taking any injuries.
 * Angelic Exorcism - Amara was able to pull Lucifer from Castiel's body. While Lucifer survived, the exorcism left him severely weakened.
 * Clairsentience - Amara instantly detected the soul bomb embedded within Dean and mocked him for thinking that she wouldn't be able to notice it during their last encounter in Alpha and Omega. In Raising Hell, Amara was able to trace the energy emanating from God's Equalizer wound and deduced that he wasn't in full strength.
 * Conjuration - She is said to be able to create a whole new reality in which everyone lives blissfully forever, but Lucifer disagrees.
 * Corrupting Effect - The Darkness' presence is a corrupting force to whatever it comes in contact with. The Mark of Cain corrupted anyone who wore it, turning them into a killer. When released, those who came in contact with the pure form of the Darkness turned into a meaningless killer. Reaper Billie told Sam that he was "unclean in the biblical sense" from being infected by a Rabid. She can also speak to the Rabids, driving them insane. She often released a deadly fog which turned humans into Rabids and connected humans to her. However, Prophets are immune, as being touched by "God power" (which both Amara and God possess) merely turns regular humans into Prophets.
 * Electrokinesis - She tortured Lucifer with powerful electrokinesis that burned his face.
 * Empathy - The Darkness can feel and influence the emotions of humans. In Raising Hell, she was able to fully interpret the fear flowing through God, when he was trying to convince her to heal him.
 * Flight - The Darkness, while disembodied, can fly in a similar manner to demons and angels without a vessel.
 * Healing - After reconciling with God, Amara was able to heal the damage her nigh-omnipotent powers did to him, without any difficulty. God believed that she could heal the damage The Equalizer did to him, but Amara refused to help.
 * Implosion - After Metatron fails to harm her with an angel banishing sigil, Amara imploded him into nothingness by surrounding him with darkness.
 * Localization - Amara was able to track Rowena after she left her side.
 * Mental Projection - Amara was able to project an image of herself and Lucifer into Dean's mind to pass a message to God and later to ask Dean to meet with her. She was also able to project a vision of herself in her grown form surrounded by her smoke form into Dean's mind to communicate with him after her release.
 * Molecular Combustion - With a wave of her hand, the Darkness caused an angel to explode into dust.
 * Pathokinesis - Amara was able to cause humans to feel blissful.
 * Possession - After her release, The Darkness possessed a newborn baby, Amara.
 * Power Negation - With a wave of her hand, Amara was able to negate Lucifer's hold over the Winchesters. She also was able to render Lucifer completely powerless against her with ease.
 * Rapid Aging - By consuming the souls of both humans and demons, she was able to incrementally age herself until the Darkness aged from a baby into a full adult.
 * Reality Warping - While she conversed with Dean, her smoke form was still expanding, causing immense winds. However, they were completely unaffected by them, indicating that she has tremendous control over the physical Universe. Her power was evident when she turned a water fountain into blood. She is able to destroy all of God's creation and even Magic itself. Prior to the creation of the current universe, she destroyed multiple worlds God created. She was also able to create matter out of nothing as she could restore Mary's body to its original state thirty years ago, in spite of it being destroyed by Azazel.
 * Resurrection - As a "thank you" for Dean helping her, Amara resurrected Mary Winchester. She was able to do this with no apparent effort despite Mary being dead for over thirty years and having left no body behind.
 * Sedation - With a wave of her hand, Amara was able to knock Lucifer out.
 * Smiting - Just by raising her hand, the Darkness was able to kill an angel with a similar effect to an angel blade.
 * Spell Deflection - While she was briefly affected by the Diminishing Spell, Amara was able to quickly overcome and deflect the spell back at Rowena and the other four witches, killing all but Rowena instantly.
 * Soul and Grace Consumption - After she was released, the Darkness started devouring human souls in order to heal herself and restore her former power. In her human form, she ate Deputy Jenna Nickerson's soul which made her grow into a little girl and later a preteen girl.  She has since consumed many souls (including demon souls). It's revealed that she can also consume the grace and essence of angels, as she consumed Ambriel, draining her from inside her vessel.
 * Super Strength - The Darkness was easily able to throw a grown man with enough force to kill him. The Darkness also blocked an attack from Castiel with ease and threw him several feet away with barely touching him. When attacking God, the Darkness was able to easily strangle him one handed even after being severely weakened by a sequential attack from witches, angels and demons.
 * Supernatural Concealment - While God could hide himself from Amara, she also was able to hide LuciferDies.giflf from God. However, Donatello was able to sense her presence.
 * Telekinesis - In the form of Amara, the Darkness displayed telekinesis. She forced an angel to kill himself with his angel blade and even overpowered God and Lucifer at the same time. AmaraFeeding.jpg
 * Teleportation - Amara can teleport anywhere in the multiverse. She used this power in various occasions and could even teleport into the Bunker, a heavily warded location with ease. She could teleport herself alone or with others in an burst of light like she did with Lucifer who was possessing Castiel's vessel.
 * Apporting - She was able to teleport Dean out of his car without a word. Later, she apported him from a city to the countryside and back. She was also able to apport her dying brother to her.
 * Umbrakinesis - As the Darkness, she has the ability to summon and control clouds of darkness for various purposes. Amara was able to use this to create tentacles of darkness to attack and fatally wound God to the point that only she could heal him and not even The Book of the Damned could do anything to help God. On another occasion, Amara gathered all of the darkness surrounding her into her being and fired it into Heaven in the form of a shockwave as a demonstration of her power.
 * Weather Manipulation - As The Darkness expanded on Earth, she caused powerful winds. She also created a deadly storm with her mind that burned people to charred skeletons. When Amara fired a shockwave of darkness into Heaven, storm clouds formed on Earth with lightning flashing throughout them violently.
 * Nigh-Omniscience - Although she is still learning about the Universe that God made while she was locked away, she was immediately able to speak the English language.
 * Mandatory Existence - Amara's existence is necessary and provides balance to reality. As God put it, "Light needs Dark", and "Dark needs Light". If she were to be killed, reality itself would end. However, it was said that if both God and the Darkness were to die, a new balance would be established.

Weaknesses
Despite her immense power, even The Darkness has weaknesses and can be sealed away or even killed. However, it takes extreme levels of combined power, as even a Hand of God used by Lucifer, which is capable of hurting Archangels, caused her no harm when used alone. Castiel once described her as seemingly impossible to destroy. Her brother God is the only being powerful enough to kill Amara, though not on his own, but he chooses not to as he says that the Darkness (Amara) and the Light (God) must both exist for the Universe to maintain balance, if either God or The Darkness cease to exist, the other also ceases together with reality itself. Thus, God opted to seal her away.

Harming and Banishing

 * Combined forces of powerful beings - The combined strength of God and the Archangels was strong enough to bind the Darkness and seal her with a lock, albeit barely. An attack by an army of demons, in smoke form, after an attack by witches and a mass-smite by angels somewhat weakened Amara.
 * The Mark of Cain - The Mark of Cain was the "lock" to the prison that held the Darkness back. As long as someone bore the Mark, the Darkness would remain sealed. Amara has displayed a great fear of the mark of Cain, claiming that she would rather finally die than be imprisoned by that Mark.
 * Lucifer's Spear - After a combined attack of angels, witches and demons it was capable of harming her vessel to the point of her admitting defeat.
 * Archangels - While a single archangel cannot harm Amara, the four archangels together can weaken her enough for God to be able to trap her.
 * Witchcraft - Although being one of the most powerful beings in existence, magic is still able to affect Amara, as Rowena used the Dark Medic Spell to heal her, and she combined with 3 other powerful witches were later able to use a powerful spell to diminish her to an extent, briefly bringing her down and burning her face and right shoulder and leaving her somewhat weakened, although Rowena's lone power proved to be completely ineffective against her and even their combined might didn't held her for long as she redirected the spell back at them, burning the 3 witches and rendering Rowena effectively helpless. God's magic, harnessed through a spell, was able to trap Amara inside the Mark of Cain when she was weakened, and despite retaining enough power to overpower God and Lucifer after she was weakened by the combined efforts of the demons, witches and angels, she had to actively resist God's attempt to recast the spell and trap her inside the Mark of Cain rather than simply withstanding it head-on, suggesting it would have worked had she not fought back.

Killing
"Castiel: She does seem impossible to destroy. [...] Sam: Is she, Chuck? [...] God: The Darkness might - might - have a weakness: Light. [...] Sam: How much light are we talking about? God: I don't know. 10,000 suns set to supernova?"

- Sam, God, and Castiel about destroying Amara


 * God - God is able to kill the Darkness, though he needs help to weaken her first.
 * Light (possibly) - According to God, a massive amount of light equivalent to 10,000 suns going supernova at once could potentially destroy the Darkness.
 * Soul Bomb - A bomb made up of a couple hundred thousand souls could potentially emit enough light to destroy the Darkness. Amara herself acknowledged the Soul Bomb was dangerous to her, further indicating had Dean detonated the Soul Bomb, it may have killed her.
 * Mandatory Existence Compromised - If God were to be killed, the imbalance would result in the annihilation of everything that exists, including the Darkness.
