Immortal

An immortal is a being that is capable of living forever, sometimes with the addition of eternal youth and/or agelessness.

Empath: The Luckiest Smurf stories
The only known immortals that exist in the EMPATH: The Luckiest Smurf story series are the gods themselves, which include both the Olympian gods and the Almighty that Tapper himself worships. The Neverstone grants the power of immortality to those who are within the range of its influence on Smurfling Island while keeping them in an ageless state.
