DISC

"A lost life can never be regained... but if you wish... If you want it badly enough... you'll be able to preserve her memory. Her heart and soul... That is your ability."

- DIO

A DISC is an item conjured and manipulated by Enrico Pucci's Stand, Whitesnake.

Appearance
The DISCs are similar in appearance to 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 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.

Function
There are two main types of DISCs:

Pucci is able to create other types of DISCs. By inserting DISCs, Pucci can command people to follow his bidding. For instance, he can brainwash a guard into thinking he's been ordered to kill Jolyne Cujoh without him dwelling much on why or how he's found himself in her proximity. The orders can be quite extraordinary and even physically impossible. For instance, Pucci has been able to command a frog to explode at a preset distance from him. Some DISCs containing a person's sense, like sight, can be extracted.

All-Star Battle
The Stand DISCs appear in 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.

Trivia
