Invulnerability



Invulnerability is the ability to withstand any amount of physical damage or harmful force, causing little if any harm or pain to the individual. All beings with this ability bodies', except for God and Death, draw blood and can be pierced and penetrated by earthly objects but it doesn't do anything.

Complete Invulnerablility

 * The Darkness - As a being who is older than God and was too powerful to be killed by God and his Archangels. It had to be sealed away and rivals powers of both God and Death, The Darkness is invincible against all demons, angels and monsters of the Supernatural Universe. Furthermore The Darkness is beyond destruction as it's is amortal.

Nigh Invulnerablility

 * God -  God is close to be completely invincible and nearly nothing can hurt, move or affect him at all, however, it is implicated The Darkness could kill him. Death, has claimed that he can reap Him, however Death died before this could be tested out.
 * Death   - Death had a considerable immunity against nearly all kind of physical and supernatural attacks, he was close to be indestructable, however he was killed by Dean Winchester with his own scythe.
 * Pestilence, War and Famine   - Weakened only by the removal of their ring, however when they assume human forms, they can receive damage.
 * Cain -  As the bearer of the Mark of Cain and the very first Knight of Hell he can't be killed by normal mean, only the power of The First Blade or The Darkness can kill him. God and Death can also kill him but not before they remove the mark.

 * Archangels -  God, The Darkness and Death can kill them without much effort, Leviathans are able to kill them as well. When it comes to weapons, only Death's Scythe, The First Blade and an Archangel Blade can destroy them as well, Magic could affect them as well to some degree, besides that, no physical  or supernatural attacks can affect them in a deadly way
 * Leviathans - Are nigh-indestructible beasts created by God. Weakened only by Borax, beheading and hunger. Magic can at least affect them. Killed only by each other, or by bibbing (eating themselves), by the Bone Of Righteous Mortal Washed In the Three Bloods of Fallen, The First Blade or  cosmological entities like God, Death or The Darkness.
 * Knights of Hell - The only weapons powerful enough to kill a Knight of Hell is The First Blade and possibly Death's scythe, God, Death and the Darkness could kill them as well.
