Nothing proceeds from nothingness, as also nothing passes away from nonexistence.
~ Marcus Aurelius


Nonexistent Physiology refers to the ability to paradoxically 'exist', yet lack any identifiable traits of existence, or exist outside of a particular scope of 'existence'. While true nonexistence in the philosophical sense is impossible to prove, lesser forms of the idea appear often in fiction.


1: Material Nonexistence: The lack of any conventional existence. Such a character will exist as something beyond the normal scope of the physical and metaphysical worlds, instead existing as an idea or other unconventional state. Such entities can be conceptualized by individuals, but do not exist in a physical or normal metaphysical form, such as a soul. In terms of binary, this would be a 0, where existence is 1 and nonexistence is 0.

2: Idealistic Nonexistence: The lack of absolutely everything to a state of nonexistence at a conceptual level. Such a state defies even the most basic logical principles and is unknowable in the truest form, as it is not a state at all. Such entities are typically presented as primordial voids or pure emptiness, or any abstract state which precedes or opposes the state of existence on all levels. In terms of binary, this would be something that is neither 1 nor 0, where 1 is existence and 0 is nonexistence.


  • As the user no longer exists, they may be unable to interact with reality.
  • Characters who exist outside of a particular scope of existence may still be affected by beings who share such characteristics.
  • The scope of what exists and what does not can vary greatly depending on the fictional continuity.
