Immortality

"I intend to live forever, or die trying."

- Several

"Some pirates achieved immortality by great deeds of cruelty or derring-do. Some achieved immortality by amassing great wealth. But the captain had long ago decided that he would, on the whole, prefer to achieve immortality by not dying."

- Terry Pratchett, The Color of Magic

The power to never age and recover from almost any injury. Opposite to Mortality

Also Called

 * Death Immunity
 * Endless/Eternal/Everlasting Life

Capabilities
Users possess an infinite life span, and can shrug off virtually any kind of physical damage. Some users are the defensive type, simply preventing such damage from appearing (invulnerability/protection), while others are the regenerative type, surviving and quickly recovering from anything you throw at them.

Variations
Some may only possess the power of:
 * Chronolock: Exist outside normal space-time continuum, and thus immune to what happens in it.
 * Death: No body to destroy. The soul, one that is not of a physical being, does not inherit physical characteristics, such as concepts of destruction, therefore cannot be destroyed; in short, the user cannot die a second time. Most common form of immortality.
 * Head Liberation: Survive decapitation.
 * Immortal Cloning: Transfer one's mind/soul into a clone to cheat death.
 * Infinite Resurrection: Death is omitted. Injuries may be inflicted, but complete annihilation is impossible.
 * Invulnerability: Cannot be harmed in any way or form, therefore death by physical damage is omitted.
 * Temporary Invincibility
 * Oxygen Independence: Survive without the need for oxygen.
 * Retroactive Immortality: Cannot remain dead, always resurrecting or reincarnating oneself after being killed.
 * Self-Sustenance: Survive without the need for bodily resources, such as food.
 * Semi-Immortality: Un-aging.
 * Quick Reincarnation: The power to be immediately reincarnated following "death"; can result in gaining powers in relation to how the user previously died.
 * Regeneration: High level regeneration of body that heals any injuries, even fatal ones, preventing one from dying.
 * Self-Resurrection: Completely heal fatal injuries and resurrect upon death if body isn't entirely destroyed.

Levels of Immortality
Semi-Immortality
 * Cannot age, thus preventing death via senescence.
 * Remains vulnerable to mortal wounds, diseases, and foreign substances.
 * Mental damage may still occur.

Reliant Immortality (Concept-Dependent Immortality, Self-Puppetry)
 * User acquires immortality by anchoring their life to a certain object, source, concept, etc.
 * Destruction of anchor ends the user's immortality.
 * The physical body remains mortal, only the soul is earthbound.
 * May require continuous intake of source or maintenance of object to remain immortal.

Immortality
 * Cannot age once reaching a certain point.
 * Immune to diseases, toxins and drugs.
 * Wounds, even crippling or fatal ones, heal near instantly.
 * Time-manipulating powers can erase the user's existence, as opposed to biologically killing them.
 * May apply only to biological immortality, as the mind and/or soul may remain mortal.
 * Immortality power may be removed, rendering the user mortal once again.

Unfettered Body
 * Cannot age once reaching a certain point.
 * Body is completely immune to physical damage, toxins and pathogens.
 * Soul and mind may remain vulnerable.
 * Per chance the body is harmed, regeneration may not occur.
 * Time-manipulating powers can erase the user's existence, as opposed to biologically killing them.

Absolute Immortality
 * Cannot age.
 * Immune to all diseases, toxins and drugs.
 * All wounds and injuries heal instantly.
 * Immortality applies to body, mind and soul, rendering the user truly "absolute".
 * Power is absolute, so it cannot be removed, nor can the user's existence from timelines.

Associations

 * Amortality
 * Omnilock

Limitations

 * Immortality Negation.
 * Cannot overcome the End of Time, unless the form of immortality is an absolute type, hence why just like Regenerative Healing Factor, it is unclear how long it would last.
 * May be erased from history via the effects of time-manipulating powers, killing the immortals in question before they become immortal.
 * While users are immune to the ravages of time, most are vulnerable against direct application used against them.
 * Nonexistence may wipe the user out of existence, as opposed to simply killing them biologically.
 * May have certain weaknesses that are lethal (i.e. decapitation, disintegration, poison).
 * May have weaknesses to single source (item, event, person, etc.) that is lethal to them.
 * May be killable by certain specific way, item or people.
 * User may go mad, from the effects of time and boredom.
 * This can also cause madness overtime because the immortal is forced to watch those who aren't immortal die.
 * Some immortals could be infertile, or they're incapable of passing this ability to their descendents.
 * Immortality may depend on outside sources and objects (i.e. Horcruxes, Shikon shards).
 * Can be sealed in an empty dimension with no chance to escape.
