Self-Sustenance

Sometimes confused with Interstellar Travel or Immortality, Self-Sustenance is a term used to describe the ability of some characters to survive and function without any form of nourishment, sustenance or energy such as air, food, water, sleep, etc. This ability also enables some individuals to survive unaided within the vacuum of space.

The lack of this sustenance does not necessarily guarantee they will die in the case of Immortality, but can inhibit their ability to function. Also a Power Depletion weakness should not be confused with the ability to survive by one's self.
