Whitesnake

Whitesnake (ホワイトスネイク) is the Stand of Enrico Pucci, featured in Stone Ocean.

Appearance
Whitesnake is a humanoid Stand of a height and build similar to Pucci's. It is sparsely clothed in black, with a mask covering its face to the bottom of where its nose would be, in a piece that rises above its head by half its height in a row of peaks, like a crown. Its attire is based on Araki's image of an executioner. Its light skin is marked by horizontal stripes of roughly an inch's height, with "GΔCT" (after the four nucleobases of DNA) repeatedly written on every other stripe. Its irises are also unique, appearing as if they are melting.

Personality
Whitesnake is sentient, with a cold, scornful, and hateful personality. It acts as Pucci's mouthpiece and avatar throughout Green Dolphin Street Jail, serving to enforce his dominance over the other guards and personnel while Pucci himself watches from afar.

Abilities
As a long-distance Stand, Whitesnake possesses an extended range (about 20 meters ), allowing its user, Enrico Pucci, to act undetected within the boundaries of Green Dolphin Street Jail. Yet it displays strength similar to that of close-range Stands; capable of stabbing Diver Down and Foo Fighters with its hands.

It is however not powerful enough to fight someone like Jolyne head-on. Thus, Pucci relies on the esoteric set of powers Whitesnake has to ambush enemies and take them down in one strike.

Illusion
Whitesnake can produce an acid that slowly digests objects like stomach acid. It is first shown to constantly exude this acid and even take a partially molten form to hide itself, but this is only used once. While dissolving, targets of this attack are distracted in a delusional dream-state. A person trapped in the dream may wake up from it by noticing discrepancies between the dream and established reality.

Later, Whitesnake is shown creating sophisticated illusions to diguise itself as other people, having at one point impersonated Weather Report to ambush the Joestar Group and approach the Green Baby.

Disc Creation
Whitesnake's primary ability is to manipulate spirits through the use of special DISCS.

Whitesnake can first and foremost extract a portion or the entirety of a person's psyche out of their bodies in the form of tangible DISCS and then put them into people. To do so, Whitesnake must touch its victim and take the time to physically "extract" the disc from them; as such, partial extraction is ineffective.

There are two main types of DISCS: Memory Discs contain a person's memory and Stand Discs contain a person's Stand. Discs may be inserted into another person's head, allowing them to either freely consult the memories inside or use the corresponding Stand, much like the original user, although Pucci can force a detrimental power into someone, for example putting a water-boiling Stand DISC inside Foo Fighters despite its dependency on water to survive.

People whose Stand and Memory discs are extracted will fall unconscious and may die, their bodily functions stopping and having to be maintained through machines. Putting back a Memory Disc inside their rightful owner will revive them. However, putting back a Stand Disc inside their owner doesn't make them well again, unlike Memory Discs. Although the Stand User can be conscious and capable of learning, the loss of even their will to live results in muscle atrophy and eventual death of the body. Weather Report is an exception to this degradation through unknown means.

People with inserted discs can gave them popped back through enough damage to the head.

Whitesnake also demonstrates the ability to insert and extract Discs of miscellaneous use. Discs can contain instructions the host will instinctively obey without question, and enables them to do seemingly impossible feats like exploding, showcasing the power of suggestion over a physical body. Pucci has also inserted a music CD into Guccio's head, causing him to function like a music player. Whitesnake is shown to be able to extract senses, depriving Pucci of his sight for instance to protect him from Heavy Weather.

Mind Control
Whitesnake is able to control people's minds directly by inserting its hand into the victim's head. The victim then willingly obeys Pucci's orders. Also demonstrated during the Heavy Weather story arc, Pucci gains control of Anasui's mind through this method.

Trivia

 * The delta (Δ) sign that replaces Adenine in the pattern on Whitesnake's body may hint at a "missing gene", or Whitesnake's incompleteness, a foreshadowing to C-Moon and Made in Heaven.
