Undead Physiology

Background

User with this ability either is or can transform into an undead, beings in mythology, legend or fiction that are deceased yet behave as if alive. A common example is a corpse re-animated by supernatural forces, by the application of the deceased's own life force or that of another being (such as a demon) or zombies, beings that come back to life and walk the earth.

Abilities

• Regeneration (Low-Mid to High-Mid, up to Low-Godly in some cases): Most undead beings can reform themselves from lethal blows or can reassemble their bodies after it's scattered, some ghost themselves can regenerate.

• Immortality (Types 3, 6 & 7): Most undead beings can reform themself, survive lethal injuries such as being stabbed or having their chest blown in and are of course undead.

• Self-Sustenance: Undead do not require things like oxygen or food to live.

Resistances

• Resistance to Poisons: Users organic functions are already dead or they do not have organic functions to begin with making them unaffected by poisons.

• Resistance to Biological Manipulation: Users biological signals are dead as they themselves are dead making them unable to be affected by things done to their biological parts, or they simply do not have biological functions.

• Resistance to Diseases: The user is already dead so no disease can really affect them and even if it did it'd do nothing to them since the things diseases affect are the parts of the user that are already dead.

• Resistance to Death Manipulation: As the user is already dead.

• Resistance to Blood Manipulation: Some undead beings like skeletons or ghost do not have blood.

• Resistance to Age Manipulation: Some undead beings like ghost would not be affected by being aged as they have no corporeal form.

• Resistance to Physical Attacks: Some undead beings like ghost aren't corporeal making them unable to be harmed physically.

• Resistance to Mind Manipulation: On the biological level as their brain no longer works.

• Resistance to Pain: Most undead beings like zombies have no pain receptors so they feel no pain when things happen like their arm being cut off.

Limitations

• Undead are usually mindless due to lacking brains.

• Some undead need to consume blood and flesh to survive.

• Undead beings like zombies usually die to damage to the brain.
