The concept of Stands is one of many things that made Jojo's Bizarre Adventure so popular. Basically, a Stand is a manifestation of the user's soul. The appearance and abilities of a Stand are all unique based on who their user is. Below are the general rules of what having a Stand are.
* A Stand protects its user, like a guardian. The name comes from "standing by" the user, sometimes using their powers without direct orders in order to protect the user, and by extension, themselves.
*A person can have only one Stand (though their Stand may evolve).
*Stands can be inherited.
*A Stand is part of its user, and damage is usually reflected between the two. Usually, if a Stand's leg is cut off, its user will lose their leg as well. Certain aspects of some Stands are immune to this effect. If the Stand is not exactly humanoid, they may reflect damage to their user's body relative to the area of the Stand that was damaged, or are an exception.
*Stands may only be seen by Stand users; the exception being Stands bound to physical objects.
*A Stand can only be directly damaged by another Stand.
*A Stand's energy or power is inversely proportional to their operating range. The further a Stand is from its user, the weaker it becomes – Long-range Stands and/or Stands' long-range abilities are simpler in mechanism.
*Stands are usually bound to their user's body, but exceptions abound
*When a Stand User dies, their Stand typically disappears with them, visually crumbling and breaking away; however, exceptions do exist.
*When a Stand is defeated, their user is either knocked unconscious or killed, depending on the level of injury.
