Sometimes called "Superhuman Durability", Invulnerability is a term used to describe the ability of some characters to withstand any amount of physical damage, pressure, or harmful force of any kind, causing little, if any, harm, or pain, to individuals gifted with this ability. Their durability, usually along with their endurance, stamina and physical health, are far superior to any ordinary being, albeit to varying degrees.

Things like knives or bullets will not penetrate the skin, and conventional punches or kicks will cause no pain. The skin and exposed areas of the body become resistant to damage, either from the very cells becoming highly durable, or some kind of physically projected force field that protects the body.

It differs from Superhuman Durability because individuals who identify with Superhuman Durability can still sustain damage from a sufficient source. Meanwhile, individuals who identify with Invulnerability have none of these weaknesses. In a manner, Invulnerability is an enhanced version of Superhuman Durability.

The degree of invulnerability can differ between individuals, from being slightly invulnerable to specific things—such as sharp attacks, blunt attacks, and energy-based attacks—to being completely invulnerable to any and all forces, akin to an immunity.

As such, most invulnerable characters are only relatively resistant to harmful phenomena and not completely immune, and additionally may possess specific limitations and weaknesses that can negate their invulnerability.
