Under World

"This is Versus's Stand... Under World takes those memories and 'excavates' them."

- Sports Maxx

Under World (アンダー・ワールド) is the Stand of Donatello Versus, featured in the sixth part of JoJo's Bizarre Adventure, Stone Ocean. It allows Versus to excavate memories from the ground and force others to relive them.

Appearance
Under World manifests as a humanoid Stand resembling Donatello's physique. Though Under World lacks a face, tube-shaped appendages shoot out from its eye-sockets directly into its back. The Stand bears a maze-like symbol and the on its chest, along with a loincloth skirt made of feathers and a checkered.

Personality
While mostly following the will of Versus, Under World demonstrates a separate personality and autonomy at times, such as going to cut Stone Free's thread without input from Versus. It is generally more calm in comparison to its user, accepting its momentary loss after being pinned by Jolyne, reasoning that they don't have time to make it to safety.

Abilities
Although Under World's versatility allows Versus to use a wide array of actions to his advantage, the Stand itself has limited fighting abilities. Oftentimes, Versus is left defenseless when fighting another Stand and loses to brute strength. The Stand and its user are vulnerable to damage even while unearthing memories, as seen when Jolyne's Stone Free injures Under World by pinning it with a plane part while the group was trapped in a memory of a passenger plane.

Mnemonic Excavation
Under World's ability is to excavate memories of events and people from the past through the assumption that the ground contains a memory of anything that happens upon it. Versus uses this to summon any historical event that happened in the range of Orlando, Florida. By digging through and uncovering the soil, Versus can also trap his foes in recreations of memories. Memories include, but are not limited to plane crashes, shootings, NFL football games, minerals, and even the people involved in recorded events. As long as Under World is not interrupted from digging up the ground, Versus can create a reenactment of the event and can also be granted knowledge of the past.

The memories of individuals who experienced the original event are aware of their status yet do not mind it, such as when one stewardess calmly informs Jolyne of their plane's impending crash. These memories are also composed of the earth and can be seen by non-Stand users. As such, if anyone is caught in an event, they will experience what has happened in the past and cannot interfere or change anything in any form. For example, if one is caught in a memory of a plane crash, they will inevitably experience said crash and die. To avoid this, one must find a loophole or condition within the memory, such as an area where nobody died or was only injured. Individuals who did not die in the original event will also not die.

Apart from trapping people in lethal events, past individuals within the memory can be interrogated for information. Anything caught in the original memory, such as stray bullets, can also indirectly attack victims within the vicinity without having to trap them in the event.

Under World is also capable of extracting Memory DISCs, as Enrico Pucci states that it can unearth the DISC from Weather Report.

Illusory Cavern
In addition to Under World's ability to unearth memories, it is also able to create a large underground cave where memories of the earth are recreated. The cave starts as a deep hole in the floor of the hospital, that opens up into a tunnel. An object can then be left as a portal to the memory, in Jolyne's case a spoon is used to transport her into the memory of a crashing plane. The cave itself has enough space for a commercial airplane, a fighter jet, and open areas for people to stand and hide. Once Versus cancels his ability the cave is revealed to be an illusion, and in reality only a shallow hole remains.
