"I don't want to achieve immortality through my work. I want to achieve it through not dying."Yes, we don't live forever. People and animals change as they age, and eventually catch disease and die. Eternal life is ingrained in the collective human consciousness, having been present in literature and myths for as long as they've been around. Literally. The Epic of Gilgamesh (the oldest heroic epic known to the modern world) is, in large part, about the titular character's search for a way to live forever. Of course, having been around for so long, Our Immortality Is Different, and comes in several flavours. These tropes are not mutually exclusive; there's plenty of room for overlap.
- Complete Immortality - A character simply can't die, ever.
- Retroactive Immortality - A character can die, but won't stay dead.
- Biological Immortality - A character is immune to the ravages of time, although usually still mortal to physical injury.
- Force of Will
- Spare Bodies
- How to become immortal? - Methods by which a mortal character can actively cheat death. Key word being actively, once the method is stopped or reversed, they either die or become mortal again.
- Incomplete Immortality
