Under World

Under World (アンダー・ワールド) is the Stand of Donatello Versus featured in Stone Ocean.

Appearance
Under World is a humanoid Stand with headphone shaped appendages on its head instead of eyes. It also has bracelets on its wrists that have checker symbols as well as a boat wheel-shaped symbol and a Star of Life symbol on its chest.

Abilities
Under World relies on its versatile power to help Versus get ahead in a fight and has no fighting ability whatsoever. Although Versus is granted a wide array of actions to use to his advantage, he is defenseless if he has to fight a Stand user head-on.

Memory Unearthing
Under World is able to excavate memories of events and people from the earth.

Acting on the assumption that the ground has a "memory" of everything that happens upon it, Under World can summon any past event that has happened in Orlando, Florida, with no limitation to its date of occurrence and scope, by digging through the soil and uncovering the underground. The memories include car crashes, shootings, plane crashes , NFL football games , minerals , and even individuals. To assist it, Versus is also granted the knowledge of everything that has happened in the past. If Under World cannot do the motion of digging up the ground, then it is unable to summon memories.

The memories of individuals are somehow aware of their status yet do not mind it, one stewardess calmly informing Jolyne of her plane's impending crash. These memories are also composed of the earth and can be seen by non-Stand users.

Similar to Bohemian Rhapsody, if an individual becomes caught in an event, they will experience what occurred in the memory (i.e. those caught in an impending plane crash will experience exactly the specific crash that is brought up) and cannot change the event. Once caught, one must find a loophole or condition in the memory to escape death, such as a certain area where nobody dies or is injured. Memories of people who don't die in the original event will not die no matter what during the replayed event, and can be used as a type of cover. This method of loopholes can only be utilized effectively if the victim has thorough knowledge of the event.

Apart from trapping people in mortal events, Under World's ability has other uses. Memories of individuals can be investigated for information, and there is a method of stealing objects off one's person by stealing the memory's possessions. Replayed events can also indirectly attack victims without catching them in an event, such as a stray bullet.

Trivia
