- Agelessness
- Aging Immunity
- Biological Immortality
- Eternal Youth
- Half-Immortality
- Timeless/Unaging Body
Capabilities
Users of this ability never age, and as a result, they stay young forever or at least never suffer the ravages of aging. Because of this, the user will always be at their physical prime. The user will also be immune to aging abilities, such as Age Acceleration or Reversal.
Applications
Associations
- Age Manipulation
- Age Negation
- Bionic Physiology
- Contaminant Immunity
- Decelerated Aging
- Immortality
- Multiple Lives
- Old Prime
- Regenerative Healing Factor
- Telomere Regeneration
- Temporal Lock
- Youth Embodiment
Limitations
- User is still vulnerable to everything else that would affect other beings, from disease to mortal wounds.
- Users may stop aging only after they reach a certain point.
- Depending on what that point is, the user may never reach adulthood.
Trivia
- A number of organisms experience "biological immortality", which is essentially the real-world version of this power. Although they don't live forever, these organisms remain in their physical prime for the duration of their lifespan and do not "grow old" in the same way that humans do.
- Unlike other forms of Immortality, this version is really hard to detect whenever it comes to physiological science. To basically put it, users of this power are still mortal, but except their bodies don't age at all, making this form of immortality half-baked in terms of functionality.
