User with this ability either is or can transform into an undead, corporeal 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).
Users with this power lack physical weaknesses, such as pain, need to rest, vulnerability to environmental effects, etc, while some still need to consume various substances (blood, flesh, life-force). Being clinically dead, their brains and bodies are immune to most powers that affect living beings.
