The DISCs are similar in appearance to compact discs but have the word "DISC" engraved on them in capital letters. A Stand can be seen inside the Stand DISCs while memories can be glanced at in Memory DISCs, although a full examination requires the insertion of the DISC.
Despite their appearance, the DISCs feel rubbery and elastic, instead of like plastic, making them impervious to physical damage. The DISCs are perennial, existing even long after Whitesnake ceases to exist, and are indestructible unless inserted into a dying person, causing the inserted DISC to slowly crumble.
Unlike Stands, an ordinary person can see the DISCs.
There are two main types of DISCs:
- Stand DISC (スタンドの
DISCSutando no Disuku): These DISCs contain the Stand of the person in question. A person with his or her Stand DISC taken from them will collapse into a near-death state. Stand DISCs can be inserted into compatible users, even enabling some such as Emporio to temporarily bypass the one-Stand rule. A Stand DISC may reject an incompatible host (such as Star Platinum's did Jolyne), so Pucci will typically seek out people whose personalities align with the Stand's abilities, such as the suicidal Thunder McQueen being granted Highway to Hell.
- Memory DISC (記憶
DISCKioku Disuku): These DISCs contain the memories of the person in question. Depending on Pucci's wishes, a Memory DISC can either store the entirety of someone's memory or individual memories.
These DISCs are mainly used to store information and abilities for later use and can be consulted or used by putting the disc inside someone's head.
Pucci is able to create other types of DISCs. By inserting DISCs with information or impossible situations, Pucci can command people to follow his bidding. Some DISCs containing a person's sense, like sight, can be extracted.
List of DISCs
The Stand DISCs appear in JoJo's Bizarre Adventure: All Star Battle as part of one of Pucci's skills and his HHA. During those special moves, Whitesnake steals a DISC from the opponent, disabling their special and Style-related abilities until Pucci takes damage. The characters who don't have Stands are not able to use their respective abilities, such as Jonathan's Ripple or Johnny's Slow Dancer.
