The Grateful Dead is a humanoid torso covered with eyes. It has no mouth. It lacks legs but has large arms, and it walks on its hands, where each have four huge metal-like and segmented fingers evenly spaced around its circumference. Hanging from its waist, where its legs should be, are four segmented tentacles. The eyes all over its body gives it the look of a yokai. Araki originally intended to draw the lower half of its body but changed his mind.
The Grateful Dead emits a light mist, but it is unknown if the mist is linked to its power.
In both the colored manga and PS2 video game adaptation, The Grateful Dead is portrayed as purple, with yellow sclera on the eyes, and orange fingers.
The Grateful Dead's greatest asset is its ability to forcefully age people over a large area, a terrifying power because of its potential for massacre.
Thankfully the aging can be slowed, and while The Grateful Dead isn't weak, it isn't a match for other close range Stands like Sticky Fingers.
The Grateful Dead has the ability to cause organisms to age physically and mentally at an accelerated rate.
There are two ways The Grateful Dead can deploy its power. The first mode is to spread the aging over a large area and indiscriminately attack friends and foes, which is dangerous for Prosciutto's companions. The second mode is to direct its power precisely by grabbing someone, in which case the aging is faster than one can react. The activation of this ability manifests itself as mist spreading from The Grateful Dead although it is unknown if the mist is directly connected to the aging.
When under the effect of The Grateful Dead, people age rapidly with all the effects it implies: their skin develop wrinkles, their teeth begin to fall, the tips of the limbs begin to necrose, the bones and joints shrink, and their cognitive ability is reduced. Infants would succumb to the effect of "aging", with their skin wrinkling and hair falling out, rather than simply growing into an adult quickly. Even fruits and flower wither and dry up.
Because the spirit is also aged by The Grateful Dead, enemy Stands are also weakened. Their power and stamina are sapped and even a powerful close range Stand like Sticky Fingers can become slower than the rather slow The Grateful Dead.
Prosciutto is normally immune to The Grateful Dead and can stay young inside its range. However, he can freely toggle the aging on himself, notably fooling Mista into thinking he's a mere civilian.
The rate at which people age is dependent on their body heat. The warmer one's body is, the faster they age. Because of minute differences between men and women's body, women also age more slowly. Thus things warming the body like intense physical activity will accelerate the aging but exposure to cold, like ingesting ice, will counter and reverse The Grateful Dead's power immediately, although both effects balance themselves and insufficient coldness will not have an effect.
