Aqua Necklace

"That one 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 a small humanoid made of fluid that can disguise itself as any liquid substance to approach its prey.

Appearance
Aqua Necklace manifests itself as a short humanoid with eyes drawn through its body. Its design references the figurines of the late Jōmon period. It usually appears in a liquid form of variable size, one time as tall as a child, another small enough to fit inside a flask.

Abilities
Particularly evasive and versatile because of its liquid state, Aqua Necklace remains lethal as it still has the power to tear through someone's innards. It is highly dangerous and it entering the body is practically a death warrant.

It is, however, unable to break through a rubber glove and any damage applied to it still transfers to Anjuro Katagiri who himself must remain close to command his Stand.

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 he acts like a sentient cloud. Because of that, it is unaffected by conventional attacks like punches and can simply reform itself.

Anjuro uses that power to trick people into drinking Aqua Necklace and then either kill them by ravaging the inside of the body or use its secondary power.

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