Immortality is the term given to people who won't die naturally. It is a common power for supernatural beings such as Gods, vampire, werewolves, etc. Other causes can be cosmic powers, mutation, etc. There as several types of immortality, each varying in usefulness.

Type 1: Immortality through longevity

Longevity grants the user the ability to live indefinitely and the inability to die of old age, illness, or natural causes, but does not prevent death through means such as being stabbed.

Examples: Elves from Lord of the Rings.

Type 2: Spiritual immortality

Spiritual Immortality is where the user can be killed (also depends on durability for usefulness in combat), but they can recreate a new body in their spirit form.

Examples: Sauron from Lord of the Rings, Ganondorf from Legend of Zelda, Darkseid from DC Comics, various Greater Daemons from Warhammer 40K.

Type 3: Immortality through regeneration

Where the user can be maimed, blown to peices, reduced to a pool of blood and still regenerate from death. Normally only higher types of regeneration qualify for this level of immortality.

Examples: Dante from Devil May Cry, Wolverineand Deadpool pool from Marvel, Alucard from Hellsing, Dark Schneider from Bastard!!, Lobo from DC Comics, Jedah Dohma from Darkstalkers.

Type 4: Immortality through godhood or protection via deity
