Dirty Deeds Done Dirt Cheap

"Allowing neighboring worlds to exist simultaneously in the same location. That is my Stand ability, "Dirty Deeds Done Dirt Cheap"."

- President Funny Valentine

Dirty Deeds Done Dirt Cheap (いともたやすく行われるえげつない行為) frequently shortened to D4C (ディー･フォー･シー), is the Stand of Funny Valentine, featured in the seventh part of JoJo's Bizarre Adventure, Steel Ball Run.

D4C is a humanoid Stand that allows its user to pass into parallel worlds at will and pull people from them back into his world. With the exception of Funny Valentine himself, if a person comes into contact with themselves from an alternative world, both of them will be destroyed.

Appearance
D4C has a humanoid form with large, upright horns that somewhat resemble the ears of a ; a masked mandible, and a light body lined by an almost unbroken seam or trim. It's designed after the image of leather being stitched together, like on a baseball. Under its brow, its eyes appear to emote a cold gaze.

After a late encounter with Gyro Zeppeli, along with Valentine, D4C's appearance changes drastically as a result of Valentine's rapid aging at the hands of Gyro's Stand, losing a layer of its face, including its horns. Even after Valentine recovers his health, D4C keeps its new form.

Dirty Deeds Done Dirt Cheap is baby blue and pink in almost all media featuring it.

Personality
D4C expresses no particular personality. However, representing Valentine's spirit across all dimensions, passing between a number of his bodies and linking each to the "root world" of the Corpse, D4C's abilities lend it peculiar depth.

Abilities
D4C is among the most powerful Stands in the series. In its default form, it is a close-range Stand with above-average strength and speed. It is able to punch a grown man away violently and rivals a transformed Diego in speed.

Although still exploring its full potential, Valentine is adept and creative with its powers.

Dimensional Travel
Dirty Deeds Done Dirt Cheap allows different parallel worlds/dimensions to co-exist at the same time and/or in the same place. It also allows its user to visit these parallel worlds/dimensions and interact with them.

Valentine travels by being closed between two objects, shown first by putting himself between a chair and the ground. Liquid materials, such as water count as objects as well, and even dust or steam. Valentine only needs an infinitesimal part of himself put between two objects to be able to hop between dimensions. Following that, Valentine may reappear from anywhere, like emerging from someone's back, presumably by affecting objects in a neighboring dimension. One of the early facets of this power was that Valentine was impervious to projectiles as the hit body part would transform simply into a hole, however, this was then left out after its initial usage.

Valentine can also pull other people or items to other dimensions by forcing them between two objects or into the object he uses as a portal; for instance he can slam a door on them while they are backed against a wall. However, as no two versions of the same person or thing can co-exist in the same dimension, one of them will have to go back into their own. If not, and if they get too close to one another, both will crumble, splitting into before obliteration, potentially causing an explosive reaction that may harm those close by. This rule does not apply to Valentine himself. Valentine can also only partially drag people into a new dimension, immobilizing them inside an object.

Diego Brando has demonstrated that people other than the Stand User can pull people to other dimensions if he reuses the same objects that were used to drag them between dimensions.

It is explained that between dimensions, gravity as a force is able to persist with Valentine when he hops between dimensions. This keeps him from breaking into pieces and becoming scattered across the different worlds.

If Funny Valentine is injured, he can hop into another dimension and transfer his D4C to this world's Valentine. Said Valentine acquires the memory of the previous Valentine and becomes the 'Root Valentine' by virtue of now possessing the Stand, but his consciousness remains different from that of the previous owner. Nevertheless, since each Valentine is dedicated to gathering the Corpse Parts and has the same personality, the differences are unnoticeable. Furthermore, he can summon any number of alternate selves to a target dimension in order to outnumber his opponents. These Valentines do not have D4C's of their own however, this Stand seemingly being wholly unique to the 'Root World', the single universe where the Corpse resides.

During early chapters, people were somehow able to see into different dimensions from different angles, but this property is never expanded on.

JORGE JOESTAR
Dirty Deeds Done Dirt Cheap also appears in the novel , although it belongs to an incarnation of Funny Valentine from the first universe as well as the grandson of Funny Valentine from the 37th universe, The Funniest Valentine. Like the original D4C, the Stand can be lent by the user to a parallel world version of himself. However, a unique attribute of D4C in the novel is that if the Stand is being lent then it automatically returns to its original owner if the current owner is killed.

As there can only be one Stand per person, the different versions of Funny Valentine in each parallel world he accesses does not have a Stand, but there are several versions of The Funniest Valentine in Funny's parallel worlds who have D4C. It is the opposite for The Funniest's parallel worlds. Thus, Funny can collect several versions of The Funniest with D4C from his parallel worlds, whereas The Funniest can collect multiple versions of Funny with D4C instead. However, these different versions with their own Stand can be destroyed by the rule if they touch each other.

Later, Kars gets his own enhanced copy of the Stand, known as Ultimate D4C.

Trivia

 * Araki states that the rabbit-like design of D4C's head came about because he wanted the Stand's silhouette to be completely different from the Stands of the previous main antagonists, so he decided to give it long ears.
 * In the English localization of All Star Battle, D4C is only referred to by the shorthand D4C, whilst the full phrase "Dirty Deeds Done Dirt Cheap" is generally changed to a synonym phrase ("Time to perform some dishonest acts at a fair and reasonable price!"). The JoJo Glossary seemingly mocks this change by claiming that "No one knows what this mysterious abbreviation means".
 * In Eyes of Heaven, it's explained that the Menger sponge-based dimension effect does not apply towards two versions of the same object or person if they are from the same timeline. This explains why two Joseph Joestars (both Part 2 and Part 3) can coexist and safely interact with each other. Two same people from alternate universes (but not parallel dimensions) are also shown to be capable of safely coexisting, such as Jonathan Joestar and his alternate universe counterpart.
