Wonder of U
It is a sentient Stand that acts as the head doctor of TG University Hospital using the name Satoru Akefu (明負 悟 Akefu Satoru). Wonder of U is capable of causing a disaster to anyone who pursues its doctor appearance or works against it.
Wonder of U is an artificial humanoid Stand, appearing robotic featuring a massive torso but thin, tubular arms, each of the articulations on those arms and the waist are pivot joints. Its entire body is covered with circular ridges that are evenly spaced, most notably the face that has exactly three below the nose level. It also has long curved blades at each wrist much like Kars.
Its head has a flattened ovoid shape and with a face only portrayed by only two coin-like eyes and the ridges below them. The entire face is framed by two pairs metallic sticks, the larger pair curves and rides along the side of the top of the head. In early appearances of it, the eyes were drawn with triangles making them appear like suns, similar to the sun motif found on Tooru's outfit.
Appearance differs depending on who sees it, to the general public, it appears as an elderly hunched man with a monocle along with his can. In his human disguise, the arms and legs are noticeably slimmer than the rest of its body. He wears a bowler hat, dress shoes, a suit, along with a scarf speckled by irregular hyphen-shaped slits. Despite his stand based existence, the clothes it wears have been shown to be somewhat tangible. Those who are aware of its ability see its true face.
Once it is revealed that Satoru Akefu and Wonder of U are the same entity, Wonder of U keeps Satoru's outfit and accessories yet his head doctor illusion appears increasing less to Rai Mamezuku and Josuke Higashikata as they understand the illusion more.

Wonder of U demonstrates an antisocial behavior, completely ignoring Josuke Higashikata, Yasuho Hirose, and Rai Mamezuku, when they first pursue it. Wonder of U remains calm as its automatic power allows it to get rid of any potential enemy before they can even harm it. Wonder of U is also perceptive, as it sees through a trap Josuke has been laying for it. Wonder of U is quite confident in his own abilities, stating that nothing can approach nor hurt him. In fact, he is surprised when Rai Mamezuku manages to get centimeters from him. When he is finally wounded by Josuke's bubbles, Wonder of U is quite shocked that anyone could wound him.
As the Stand of a Rock Human, Satoru asserts his dominance, probably over humans in general, when he declares that "they" have no permission to possess anything, be it a pear orchard (referring to Mamezuku's Father) or the new Locacaca (referring to Josuke and Rai). He also values the Locacaca6251, noting their price tag of 200 million yen, but also highlighting their value to the world as a miracle medicine. The sight of Josuke wrecking his supply notably goads Wonder of U into approaching Josuke.
Wonder of U allows Tooru to lead a double-life under the assumed identity of Satoru Akefu, allowing him to act as the head doctor of TG University hospital. This is done by Wonder of U taking on a human form, which unlike most Stands, can be seen by non-Stand users. This allows Tooru to gain access to both the hospital resources and presumed credentials needed to carry out his role as presumed mastermind of the Locacaca Organization.
Long-range Illusion Creation
Wonder of U is able to create multiple visions of itself, which can be designated to specific targets. These visions normally take on the form of Tooru's assumed identity, and typically position themselves so that their back faces a given target. Wonder of U has been shown to have a degree of control over who can and cannot see these visions. For example, a vision meant for Mitsuba Higashikata could not be seen by other members of the Higashikata family, while another vision of the Stand could be seen by a large audience attending the head doctor's presentation. Even in human form, Wonder of U's illusions are able to phase in and out of objects such as walls, and are able to travel across reflective surfaces.
Wonder of U's primary ability is automatic and functions at a long range. It is extremely dangerous because there is little defense against it.
Wonder of U's ability can be activated on any person who has looked at the Stand's back while in its human form. While Wonder of U's ability is active, targets will experience horrible developments referred to as calamities. Some calamities will be a result of the target's own behavior leading to an unusually detrimental result (i.e. Mitsuba cutting her hand while preparing food) while others take the form of environmental factors that would normally be harmless having an abnormally bad outcome (i.e. Josuke receiving near-lethal wounds from the impact of raindrops, or a light bulb in Mamezuku's vicinity exploding). As a rule, Wonder of U's calamities always manifest themselves as some form of harmful collision.
Once Wonder of U has locked onto a target, any attempt to pursue or otherwise harm Satoru Akefu will result in the ability reactivating. The threshold for reactivation is extremely sensitive, as the mere intent to confront the Stand's presumed user was enough for the ability to target and nearly kill Josuke. While pursuit is the Stand's most common trigger, Wonder of U can also attack any person who sees the back of its presumed user, regardless of whether or not they hold the intent to pursue. This was demonstrated by Mamezuku, who showed another prisoner in his holding cell a photograph of the Stand's back, resulting in the latter being mortally wounded.
There is a strong correlation between the size of an object and how immediate and severe the injury will be upon impact. For example, while a discarded cigarette striking Josuke's hand resulted in it immediately piercing his palm, colliding with an umbrella stand caused a much more serious wound on Mamezuku's leg, though with a noticeable delay between the collision and appearance of the injury. It seems that for collisions with larger objects, there's a waiting period in which the effects of this impact can be transferred to another person. A bystander was shown to suffer a sudden, fatal neck injury after coming into contact with Josuke's blood within moments of the latter being hit by a car during this Stand's attack. As stated by Mamezuku, the severity of the calamities caused by the head doctor to someone who is not pursuing him seem to function as a form of karma and are influenced by an individual's history. This is demonstrated when a convicted killer who caught a glimpse of Wonder of U's back received a calamity that resulted in a life-threatening wound, while Mamezuku's took the form of relatively harmless things, such as a light bulb bursting and maggots appearing in his uneaten food. This is further expanded upon by Wonder of U, stating that there is a "flow" of things that always results in calamity which was previously hinted at by Tooru.
However, despite Wonder of U's seemingly unbeatable offensive and defensive capabilities, a possible weakness in its defense is noted by Josuke following his initial defeat by the Stand. By remaining completely idle and forcing the Stand to confront him, Josuke was seemingly able to bypass the danger of the Stand's ability, as no behavior or environmental factors were present that could be extrapolated into a calamity.
He is pursued by Josuke Higashikata, Rai Mamezuku and Yasuho Hirose but effortlessly escapes thanks to his calamity power. During their chase, he briefly appears behind Josuke but disappears as Josuke attacks him. Several days later, Josuke and Rai are in a car and discuss how they'll approach Satoru Akefu during his lecture on regenerative medicine. This triggers Wonder of U, who again briefly appears behind Josuke and activates his calamity power.
At roughly the same time, Mitsuba Higashikata keeps seeing Satoru Akefu lurking near her. As the day of the harvest approaches, a calamity strikes and Tsurugi's illness goes out of control. The day of the harvest, Wonder of U's calamity affect the Higashikata Family and Yasuho, who has come to investigate the house. Yasuho nearly drowns and loses an arm, Jobin has to take out Norisuke, and Jobin himself is gravely wounded by the calamity. Tooru arrives at the scene.
Meanwhile, Satoru also gives a lecture at TG University Hospital, unveiling the Locacaca6251. However, after the lecture, a journalist named Taoka shows him evidence of illegal trials and threatens to make this public. Wonder of U is thus alerted and heads towards the secret Locacaca laboratory, letting the calamity dispose of Taoka.
When he arrives at the laboratory, Wonder of U senses that something is amiss and doesn't step into the room. Instead, he deploys a Rock Insect named Dododo De Dadada and sics it on Josuke and Rai Mamezuku.
Wonder of U lets Dododo De Dadada attack Josuke, but Rai Mamezuku eventually intervenes and kills the Rock Insect. Rai approaches Akefu and confronts him, waving his sharp fingertips two centimeters away from Akefu's face, and with seemingly no calamity in sight to stop him. As he approaches the tip of his wire into Wonder of U's face, Mamezuku begins to claim that the Stand's power of calamity could be a trick. Akefu openly wonders what could happen as nobody has ever gotten this close to him but declares that still, nobody can attack him. Then, Akefu presses on Mamezuku's past, reminding him of the time his father died, how a mysterious insect laid waste to the Mamezuku family's orchard, and how Mamezuku's mother fell ill and died as she was overwhelmed with all the calamities that had happened. Angered by the taunt, Mamezuku directly grabs Akefu by the neck and threatens to impale it with his fingertip.
Suddenly, one of Mamezuku's braids flies off. Mamezuku narrowly missed Satoru Akefu's neck and spherical chunks of flesh have been taken off his shoulder. Josuke sees that his own soap bubbles were responsible for wounding Mamezuku. The head doctor thus realizes that this was Josuke's trap: Josuke had laid several bubbles in the room but some of them were hidden and spinning at high speed. By letting Akefu come to him, Josuke had hoped to let these trapped bubbles kill the enemy Stand but instead, by sheer unluck, these bubbles wounded Mamezuku instead. Worse, one of those bubbles just pierced through Mamezuku's head.
As Mamezuku collapses, Wonder of U's confidence in its invincibility is reassured. However, Mamezuku is not dead yet and reveals the power of the Spin to Josuke.
Wonder of U asks again if Josuke intends on approaching him. Josuke briefly reflects on the true nature of his bubbles before regaining his focus. He declares that he's been the one making Wonder of U approach him. To bait him closer, Josuke summons Soft & Wet to destroy the vault containing all the Locacaca6251 test tubes. He disperses the tube and even destroys the doors with explosive bubbles. Wonder of U protests, stating that even if he will take the new Locacaca, the Locacaca6251 remains extremely valuable and that the world needs it. Hearing about the medicine price of 200,000 yen for a test tube, Josuke snarks about his 7,890 yen sneakers and stomps on the test tubes. Wonder of U finally steps into the room and approaches Josuke, while carefully staying clear of Soft & Wet's bubbles. However, Wonder of U then suddenly informs him that Yasuso is at the Higashikata estate and that she's in danger. Josuke hesitates for a moment, and resumes destroying the test tubes with even more fervor. However, a piece of glass ricochets into his neck. Wonder of U expresses incomprehension at Josuke's stubborness and explains how the flow of calamity will attack him through all of the objects that the Stand is touching. At the same time, he ostentatiously touches the test tube and the wreckage of the vault. Josuke tries to high kick Wonder of U in the neck, but a bubble gets in the way and cuts a part of his leg. Josuke trips and impales his shoulder on a metal rod sticking out of the wreckage. Wonder of U expresses his satisfaction, but suddenly a gust of wind comes from inside of the vault. Born This Way appears. With its freezing wind, the Stand freezes several bubbles and sends them at Wonder of U, who tries to deflect them with his cane. However, one of the bubble hits Wonder of U and wounds his head, shocking the Stand.
Although Kei Nijimura is mortally wounded, Tooru deems that Josuke is still too dangerous to come close to. Wonder of U thus leaves the room. He heads towards the elevator and notices Josuke pursuing him. Confident that he will be safe, Wonder of U quips at Josuke before stepping into the elevator but Josuke shoots one bubble at him. However, Wonder of U had planned for this and summons a Rock Insect named Obladi Oblada that deflects the bubble and latches onto Josuke. Wonder of U enters the elevator. As Obladi Oblada begins to multiply itself and cover Josuke, Wonder of U explains a bit of its biology and taunts Josuke, who is now covered in the Rock Insects. Wonder of U closes the elevator door, but Paisley Park then hacks into it, forcing the door open and allowing Josuke to confront the head doctor at point-blank range. Josuke shoots a second bubble, but Obladi Oblada gets in the way and deflects the second shot too. Wonder of U watches as Josuke collapses, overwhelmed by the insects, but then Paisley Park brings the invisible bubble that's shot out of Josuke's birthmark with it back to the Higashikata House. The bubble then flies right towards Tooru.
