Wonder of U

"I am "Wonder of U", and the "flow" is always a calamity."

- Wonder of U, JJL Chapter 99

Wonder of U (ワンダー・オブ・U (ユー)) is the Stand of Toru, featured in JoJolion.

Appearance
Wonder of U has two forms, its main stand form and its disguise of Satoru Akefu, the TG University Head Doctor. As Satoru, Wonder of U appears as an 89 year old man, stooped and walking with a cane. He wears a black bowler hat and coat, gloves, and a scarf. His coat features buttons that resemble small suns. Usually, the doctor is only seen from behind, but when his face is revealed, he is shown to be an old man with a monocle, braided hair, and a series of spikes surrounding his mouth. In its human form, Wonder of U is visible to non-stand users, but it is unknown what they see when the stand teleports between locations or assumes its non-human form.

In it's stand form, Wonder of U stands upright and Akefu's human face is replaced by a mechanical head which resembles a radio microphone or a machine. Its eyes are shaped like suns, similar to the coat buttons. Underneath its clothing, Wonder of U has a slim, articulated mechanical body with a pair of blades on its arms.

Personality
Wonder of U is a sentient Stand that is considerably expressive and holds a calm yet threatening demeanor.

It's surprised when Rai Mamezuku gets as close as a few centimeters to it. When it's wounded by Josuke's bubbles, Wonder of U is shocked that anyone could wound it.

Wonder of U is perceptive, as it sees through a trap Josuke has been laying for it and quickly analyzes the threat that Josuke could pose. Wonder of U is fairly resourceful, as it takes care to avoid direct combat by utilizing rock insects. As Josuke discovers a new aspect to his Stand's bubbles, Wonder of U decides that the best course of action is to simply retreat.

The Stand goads its enemies into pursuing and triggering its ability, an example of this being it revealing to Rai Mamezuku that it killed his father.

Wonder of U asserts its dominance over humans in general, such as when it declares that they have no permission to possess anything. It values the Locacaca 6251, noting their price tag of 200 million yen, but also highlighting their value to the world as a miracle medicine. Josuke wrecking the supply goads Wonder of U into approaching Josuke.

Wonder of U has a habit of occasionally stating its name in conversation.

Abilities
Wonder of U is arguably one of the most powerful Stands introduced in the series. It is able to contend with many formidable Stands and come out victorious, and even continue to activate after it's user's death.

Though Wonder of U is an automatic stand, Toru seems to have a limited ability to control Wonder of U directly, effectively allowing him to be in two places at once. When Toru is actively controlling Wonder of U, his eyes glaze over and have a dull look. When Toru is back in control of himself, Wonder of U seems to stand facing a wall if it is not actively reacting to a pursuer. If someone observes the stand in this state, they will see Satoru Akefu with his eyes dull and glazed over.

While the specific stat rankings for Wonder of U are not known, it has demonstrated proficiency in using its cane as a defensive tool. It has been shown rapidly deflecting a flurry of frozen bubbles as well as deflecting a precision shot from Josuke.

Calamity
Wonder of U's main ability revolves around the concept of 'Calamity', bringing impending doom to anyone pursuing Toru or Akefu (the Stand's 'human' form). The pursuit does not have to be in the form of a direct chase, as even the intention, will, or desire to pursue Wonder of U in the future will cause the stand to activate. The intent to pursue seems to need to be more than just coincidental, however, as Akefu had to coax a declaration of intention out of a reporter who threatened to expose him. Only when the reporter's intention was clearly stated to be in pursuit of Akefu and the Rokakaka was Wonder of U able to kill the reporter with a calamity. This is in contrast to the crowd of hundreds of people who came to the hospital with the specific intention of listening to a presentation given by Akefu, none of whom were affected by a calamity.

It is also possible to act in a way which would cause Toru or Wonder of U to pursue the target, instead of the other way around. If this occurs, the stand will not activate its ability. This makes it possible to close the distance with the user or the stand without triggering it.

The exact form the calamity takes varies, but always involves redirecting aspects of the nearby environment towards the target in a harmful manner. Upon contact with any object influenced by part of the calamity, the target receives an extremely disproportionate amount of damage, especially from impacts. The damage the object can cause will only affect the target, and not obstacles in the way or bystanders unaffected by the calamity. Objects touched directly by Wonder of U can be "charged" with calamitous energy as well, allowing the stand to create additional area hazards. If the target manages to avoid or survive a calamity, another one will always follow shortly afterwards. Examples of this ability include:


 * During a pursuit of the head doctor, Rai Mamezuku tripped over an umbrella stand hard enough to cause compound fractures in both legs.
 * A bus containing the head doctor kicked up a cigarette butt with enough force to penetrate Josuke's hand.
 * While slicing vegetables, a minor slip of the knife resulted in Mitsuba Higashikata cutting off two of her fingers and triggered a chain reaction of events that nearly led to her being lethally scalded by oil.
 * When Josuke and Rai were caught in a rain storm, the raindrops hit with the force of bullets - penetrating through limbs and doing enough damage to knock Josuke unconscious and require a trip to the hospital.
 * At the hospital, a police officer who Josuke knocked out fell on top of him, breaking two ribs and damaging his left lung in the process.
 * A leaf on the Higashikata estate fell with enough force to slice off Joshu's fingers.
 * The instant Yasuho continued to pursue Toru at the Higashikata estate, a piece of an airplane 10,000 meters above ground broke off and fell directly towards her.

The stand can even influence the Locacaca's 'Equivalent Exchange' - when Josuke tried to drink the serum while still intending to pursue Wonder of U, the exchange happened in a way that threatened to suffocate him. Only when someone else without the intent to pursue administered the serum for him was it able to perform a normal exchange.

Wonder of U will apply calamitous effects to any object in the area of the target in an attempt to kill or disable them. When Rai was testing the limits of Wonder of U's ability while in prison, he was attacked by spilling liquid and an exploding light bulb. When those calamities failed to damage him, a normal tray of food suddenly became diseased, and erupted with maggots and a dying rat.

In the absence of any objects which can be propelled at the target to create an impact, Wonder of U seems to have the ability to affect nearby people and influence their behavior or actions. This was first seen in the Hospital parking lot when a nearby patient got unusually angry with Josuke and advanced to touch him. When Josuke prevented contact using his bubbles, the man's neck snapped 90 degrees to the side, killing him instantly. This has also been observed with a prisoner going into a rage and attacking Rai and Joshu going berserk and attacking Yasuho.

Dying from a calamity or losing the will to "intend to pursue" either Toru or Akefu will remove the target from the calamity priority stack.

Posthumous Activation
It is revealed in Jojolion chapter 108 that even after Toru's death, Wonder of U can still function due to the fact that it represents, and is made from the idea of the Calamity itself, with Rai even theorizing that it was born from a some type of "calamity energy". This makes it the second stand to be made out of a supernatural force, the first being Ball Breaker.

Miscellaneous
It's unknown that it's its own ability or the Rock Human's, but Wonder of U is able to disguise itself into Satoru Akefu and can also undo it anytime. This ability allow Toru to freely use the hospital as a secret lab for Locacaca research.

The stand can also phase through walls and hover in the air. It also seems to be able to teleport at will, as it completely disappeared when being pursued by Rai. Later on, it was able to instantly shift places between TG University Hospital and the Higashikata House. In addition to its ability to teleport directly between locations at a distance, Wonder of U can also move rapidly within a smaller area by gliding along and within flat, reflective surfaces.

Trivia

 * Wonder of U's stand design and appearance on many covers are based off of artist René Magritte's work, for example ' The Man in a Bowler Hat' for the stand's true form.
 * Wonder of U is the second stand of a main antagonist to not have some sort of ability regarding time, the other being D4C.
 * In JoJolion Chapter 97, Toru can be seen listening to The Wonder of You by Elvis Presley on his MP3 player. This makes Toru the first stand user to listen to his stand's namesake in-universe.
