Invulnerability

Invulnerability is the power or ability to be immune to any injury.

Entities possessing this power
- Despite what you think, no being in or outside of Creation is truly invulnerable, but some have very specific weaknesses and things that can harm them, having varying levels of invulnerability.
 * Gods: God and Goddess are nearly invulnerable. However, they can still be killed by each other and by the Flaming Sword. For a while, Goddess's powers were greatly weakened but they have since returned. While using human hosts, the bodies had human vulnerabilities, but Goddess was able to go to a new host when the previous one was killed.
 * Angels: As celestial beings created by God and Goddess, angels are nearly invulnerable. However, they can be killed by gods, as well as certain objects like Azrael's Blade and the strongest of demonic blades (however, this last one only applies to weaker angels, unlike the Arch-angels like Lucifer and Michael).
 * Demons: As malevolent entities that originate from Hell, demons possess an elevated degree of invulnerability. However, there are quite a few objects and beings that can injure and even kill them- but higher up demons are tougher and less vulnerable, like demons sitting on the 'Council of Hell'.
 * Chloe Decker: Considering her resistance to Lucifer's powers, as well as other powers used on her and how she affects him, Chloe possesses some mysterious type of invulnerability that is above that of a regular human.
