Absolute ImmortalityPower/Ability to:

Possess "true" immortality.

The power to be eternal and indestructible. Sub-power of Omnipotence. Absolute version of Immortality.

The user is absolutely immortal, and can not die, age, get sick, be permanently wounded, is absolutely self-sustained and, as their mind and soul are as immortal as their biological bodies, they are immune to mental/spiritual damage. Any injuries the user suffers immediately heal, even if the user's body is disintegrated or blown up or completely erased and even if the user is completely destroyed to the sub-atomic level, they will still return to life. Alternately, some users are absolutely immune to all harm, and can never die from any natural causes.

The user's existence and soul become completely free and independent of even the concept of reality, making them unbound to the subjects of life, death, and manipulations. Also, the power cannot be removed, rendered truly perfect and absolute.
