Invulnerability

Invulnerability refers to a physical being's ability of not being able to be hurt or damaged by anything in any situation. This is mostly used in comic books when referring to superheroes such as Superman, who is invulnerable to all things except for Kryptonite and magic.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, Empath and the Psyches are able to resist most common types of injury, with Empath receiving this through some genetic enhancement therapies by the Psyche Master during his time in a gestation chamber. However, neither Empath nor the Psyches are invulnerable, as they are capable of being killed as any mortal being.
