Stands


Stands are the main power system that is used after Part 2 and almost every named character has a Stand. Stands are a physical representation of its user's soul which the Stand User can use to protect themselves from any harm. Most Stands are different from each other although some Stands are very similar (See Star Platinum and The World which were stated to be "The same type of Stand"). All Stands follow a set of rules such as only Stand Users can see Stands, only Stands can harm other Stands, any time a Stand takes damage then so does its user (With an exception of Automatic Stands which are completely detached from its user), when a Stand is destroyed then so is its user, when a Stand User dies then their Stand will be destroyed, Stands will get weaker and slower the further they get from their user and most Stands will protect their user from any potential harm.

While it is stated that only a Stand can harm another Stand, this is shown to be untrue when ghosts and other spirits are able to harm Stands which means that anyone who can physically interact with souls can physically interact with a Stand.

Each Stand has an ability that it can use, whether it be the ability to manipulate time, change the age of people or even rewrite reality. While some Stands are weaker than other Stands, it's their abilities that make up for that weakness making Stands that can't lift up a strand of hair deadlier than one could imagine.

While most Stands only have one ability some have a second ability known as a Sub-Stand. A Sub-Stand is an additional Stand which is tied to their main Stand which grants the user an extra ability. Examples include Yoshikage Kira's Sheer Heart Attack, Giaccio's White Album's Gently Weeps and Diavolo's Epitaph.

Stands come in multiple types. There are Close-Range Stands which have short range but are the physically strongest, Long-Range Stands

Stand Arrows


The Stand Arrows are the main way for a person to gain a Stand. They were originally crafted from a meteorite which contained an alien virus which culled weaker life forms and would give stronger life forms an ability to survive that being a Stand.

The Stand Arrows give people a Stand by piercing any part of their body at which point they will be injected with the life culling virus if they are accepted by the virus then they will have the injuries healed and will be able to use a Stand, however, if they are not chosen then they will be killed even if the arrow only lightly pricked their finger.

The Stand Arrows themselves have their own will and will be pulled to anyone who has a notably strong will in order to give them a Stand.

If a Stand User is pierced by the Stand Arrow again then their Stand will be given an additional ability as shown when Yoshikage Kira's Stand Killer Queen gained a third ability known a Killer Queen Bites The Dust.

Rock Humans
Rock Humans are a separate species than anything else we have seen in the series. They are human like life forms that
