"A walking skeleton, the basic frame of the human body, can inspire more fear in the common man than an excessively armed soldier or knight."
― Jacob Deegan, Dominic Deegan
"I am just dead and bones only Brook!! It's a Pleasure!!!"
― Brook to the Straw Hat Pirates (One Piece)

The power to take the form of a living skeleton. Variation of Undead Physiology and Wight Physiology. Not to be confused with Bone Mimicry.

Also Called

  • Skeletal Physiology
  • Skeleton Mimicry


The user with this ability either is or can transform into a skeleton, a type of physically manifested undead often found in fantasy, horror fiction, and mythical art. Though most are human skeletons, they can also be from any creature or fantasy race found on Earth or in a fantasy world.

Users with this power lack physical weaknesses, such as pain, need to rest, vulnerability to environmental effects, etc. Biological functions available to the skeleton vary but most are gone, remaining such as sight, smell, hearing, and touch are done through mystical means even if they lack the necessary organs to do so.

Being only bones, they tend to be more fragile than other undead, but their relatively small body-mass may make actually hitting them a problem. They are often fast and agile, which is justified by their low weight. Most are mindless and rather low-level opponents, but others are not only sentient but very powerful indeed.



Types of Skeletons



  • May be difficult, or impossible to revert back to a normal form.
  • Blunt attacks may be particularly damaging.
  • Bone Manipulation, Dark Arts, Necromancy and other forms of Magic may be used to control the user.
  • May lack any regenerative functions and thus must rely on grave robbing and skeleton scavenging for bone replacement.
