Aqua Necklace

"That one's got a sharp eye. If only she or her kid from yesterday drank that milk... Then my stand Aqua Necklace could have taken control of their bodies!"

- Anjuro Katagiri, DU Chapter 4

Aqua Necklace (アクア・ネックレス（水の首飾り）) is the Stand of Anjuro Katagiri, featured in the fourth part of the JoJo's Bizarre Adventure series, Diamond is Unbreakable.

It is capable of possessing the properties of any liquid substance to approach its prey, eventually destroying its target from within their body.

Appearance
Aqua Necklace is a muscular humanoid Stand with liquid covering its body. Its size varies, though it's usually depicted as being small. The Stand can either be the size of a human child or shrink itself to fit inside various containers such as within a person's body.

Aqua Necklace's design is based on figurines from the late. It has thin eyes and small irises, along with a prominent nose and lips. Aqua Necklace also has sharp teeth and numerous large eyes all over its body. Its head resembles a helmet with a split in the middle and small circles surrounding the edges, above its eyes. It has a wavy line on both sides of its face, extending from the back of its head to above its eyes and continuing below its eyes to its chin.

Aqua Necklace's lower body is normally fluid as it can move around quickly in that state rather than showing its legs.

Abilities
Aqua Necklace is a Stand that is particularly evasive and versatile because of its liquid state. Its destructive power is weak and it's difficult for it to escape once it's captured, such as when Josuke traps it in a rubber glove. Any damage applied to it also still transfers to Anjuro Katagiri who himself must remain close to command his Stand.

However, Aqua Necklace is lethal as it is capable of taking over a person's body and tearing through their innards. It also has a range of several dozen meters and can be activated for a long time.

Liquid Form
Aqua Necklace may disguise itself as any kind of liquid and take on their properties. It is usually water but the Stand has been shown to adopt the guise of brandy or even vapor in which case it acts like a sentient cloud. Consequently, it is unaffected by conventional attacks like punches and can simply reform itself.

Anjuro uses that power to trick people into drinking Aqua Necklace. The Stand then either kills its victim by destroying their body from within or possesses them.

Possession
Aqua Necklace is capable of possessing people from the inside to control them by easily forcing itself into the body through its victim's mouth. While inside, it has control over its victim and can act through them, at one point taking someone hostage for fun.
