King Crimson

King Crimson (キング·クリムゾン) is the Stand of Diavolo, featured in Part V: Vento Aureo.

Appearance
King Crimson is humanoid Stand of a height and build similar to Diavolo's. Its body is covered by a raised diagonal grid, red underneath; save for its face, neck, shoulder guards, elbows, hands, abdomen, crotch, knees and feet/footwear.

Its eyes comprise sharp orifices of a steep inward slant; from which emerge small, round fishlike/amphibian/reptilian eyes. It constantly bares its teeth through a small mouth. Its crown is flat; and from its forehead emerges two raised levels, the front of which bears a smaller, oval face of the same expression.

Its design is inspired by the character George, from the 1990 science fiction film Total Recall, who had a second face on his chest.

Erase Time
Erase Time: King Crimson's signature ability is to put it simply, skip time. To go into detail, it deletes about 10 seconds worth of time, during which only it can move and predict the movements of other people. No living creature on this world can experience or remember the deleted time. The moving arms of a clock and flying birds seem like they teleport, and people forget how much of a book they've read. Its weakness is the short range and low durability, so taking on multiple people at once could result in someone finding out the user's identity.

To Diavolo, moving while deleting time like this appears in the form of the would-have-been intervening objects' states being superimposed on each other, in a fashion akin to Nude Descending a Staircase.

The nature of the time erase is such that, for example, a bullet that would have hit Diavolo will suddenly be shifted to be on his other side as where it would be seconds later.

The ability to erase time also appears to be relevant to Diavolo's own stamina, as he admitted to Risotto Nero that in the weakened state his body was in from the lack of iron in his blood, he would only be able to erase time for barely more than an instant.

Epitaph
Prediction: Doppio is able to utilize a type of weaker and defensive sub-Stand of King Crimson called Epitaph (エピタフ). The same face that appears on King Crimson's forehead (Epitaph) appears on Doppio's, and according to Diavolo, Doppio can also utilize King Crimson's hands as his own. However, the use of the sub-Stand seem to be usable only by permission.

Epitaph also gives Doppio a preview of what will occur in the next ten seconds, allowing him to react and defend himself accordingly. As stated by Diavolo; no matter what, the prediction cannot be prevented (only the ability of Gold Experience Requiem has been shown to bypass this), but Doppio can still use it to change minor things. For instance, one of Epitaph's predictions allowed Doppio to see his foot being cut off, and with proper tactics, it changed so Risotto Nero's foot was cut off instead.

It's theorized that the powers King Crimson have are actually split due to Epitaph's existance, much like how Diavolo and Doppio are split personalities: King Crimson can alter time, but without Epitaph, Diavolo wouldn't be able to see the future.

Offense
Super Strength: King Crimson is one of the strongest Stands, rivaling Star Platinum and Crazy Diamond.

King Crimson was shown to have killed several people just by punching them right through their stomach with one blow, and above that it seemed that a tremendous amount of endurance was needed just to take one hit from King Crimson without the person suffering a tremendous injury; even Giorno lost his entire arm due to the power of a single strike.

Faster-Than-Light Speed: King Crimson has shown to be able to easily parry, react and even outmaneuver faster-than-light Stands like Silver Chariot, Sticky Fingers and Gold Experience, even without the use of Epitaph. King Crimson's speed may even be comparable to that of Star Platinum.

Trivia

 * The sub-stand is based on King Crimson's song, Epitaph.
 * King Crimson's time erase has been utilized with very obvious effects, but the mechanics of the time erasure themselves are not as well understood.  This is atributed to the manga having not only a poor-quality English translation, but also the different uses King Crimson has throughout Part 5.  As a result, saying "It just works" is the most common answer to how King Crimson works.  Noticably, the two games Diavolo are in have different interpretations:
 * In GioGio no Kimyō na Bōken: Ōgon no Kaze, the time erase was shown to slow down the opponent's actions while Diavolo still moves at normal speed for the duration of the obliterated time, a mechanism similar to Made in Heaven's time acceleration abilities.
 * In All-Star Battle, it acts similar to The World - through a counter, Diavolo creates a skipped time space in which he is free to move about and the opponent is frozen in space, but by attacking the opponent, the spell is broken.  King Crimson also acts as his dash and Epitaph can be activated to allow Diavolo instant dodging without taking out his guard meter.
 * However, interesting glitches were found in ASB involving King Crimson's counter and Epitaph.  If Diavolo activates the King Crimson time-skip counter while he's hit with a projectile, followed by the opponent activating a HHA or a GHA, there are interesting results.  There is also a glitch involving using his HHA and then dashing through the opponent, resulting in another bizarre moment.
 * Physically, King Crimson is possibly one of the strongest Stands in existence. Unlike Stands like Star Platinum, it normally attacks not with a sequence of punches, but rather with a single attack. It is also possibly one of the the fastest Stands in existence. It is able to easily parry, react and even outmaneuver faster-than-light Stands even without the use of Epitaph.
 * Due to being hit by Gold Experience Requiem, Diavolo effectively had his Stand destroyed as the final attack removed all of Diavolo's "willpower", which is what powers the Stands.
 * In the western release of All Star Battle, King Crimson is renamed as "Emperor Crimson", while Epitaph is renamed to "Eulogy".
