Gold Experience Requiem

Gold Experience Requiem (a.k.a. Requiem or GER) is a stand power featured in Part V: Golden Wind. It is the second stand of Giorno Giovanna and the evolved form of Gold Experience created by piercing its body with the stand-creating Arrow. When Requiem first appears, it wears the arrow on its forehead, but eventually the arrow falls to the ground. It is not known if Giorno keeps Requiem's form after the arrow falls to the ground.

Abilities
Nullification of Action and Effect: Gold Experience Requiem's ability is to turn anything, including his opponent's attack and willpower, back to the state of "zero". Hence, it is near invincible, as all "supposed" actions created by an opponent would have been reset (back to point zero). It is mentioned by Giorno himself that he is unsure of the exact workings and limits of Requiem's powers, but it has been shown that its range of influence extends from finger beams, surface contact, and to even being in the mere attention of Requiem. Requiem also appears to have a consciousness of its own that is unknown to Giorno.

Requiem's abilities also seem to be opposite King Crimson's: King Crimson erases the "cause" and keeps the "effect" (i.e time where a bullet would hit him is erased, causing the bullet to warp past him), while Requiem keeps the "cause" but erases the "effect", causing endless scenarios where actions and initiatives are started, but the effects of such does not occur (as shown when Requiem completely halted King Crimson's cause erasing ability).

If the opponent is "killed" by the stand itself, then they will also continuously experience death, as they will die but repeatedly return to point "zero" (i.e Diavolo's endless death loops).

This ability turns Giorno essentially untouchable by anything that would try to hurt him and is perhaps the strongest defense in the series.

Original Abilities: It is often disputed whether Giorno retained his original life giving abilities after evolving into Gold Experience Requiem. After fusing with the arrow, Giorno breaks a column and a piece of it turns into a scorpion that then attacks Diavolo, so it is very likely he still has all of his original stand's abilities.
