Wonder of U (ワンダー・オブ・
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 with a mostly black body. It has a doll-like body, with a massive torso but thin, tubular arms. Each of its articulations, from the waist to the elbows, is a pivot joint. Its body is covered with light circular ridges that are evenly spaced. It also has a long curved blade at each wrist much like Kars.
Its head has a flattened ovoid shape, still black with the same ridges around its head. Moreover, it has a reverse U-shaped ridge framing its face and a pair of round mechanical eyes. The eyes are decorated with a sun motif, similar to the symbols found on Tooru's outfit.
The Stand is capable of appearing as an elderly-looking man with a slightly stocky build. Its arms and legs are noticeably slimmer than the rest of its body. It wears a dark-colored hat and suit, along with a lightly colored scarf with a pattern of irregular "-" shaped slits cut into it. It also wears dress shoes and uses a cane to walk.
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 able to create illusions which can be sent after a specific target. It can disguise itself and take on the appearance of a human, allowing it to interact with ordinary humans. Secondly, Wonder of U can create projections of itself. These projections are able to travel quickly between locations by phasing into and appearing on transparent surfaces, such as windows or picture frames. As a result, despite these illusions only being visible to the attack's designated target, they're able to be caught on camera. So far only people who have seen the head doctor in person have been targeted by these projections, though any individual who sees an image of the Stand will also be attacked.[2] Wonder of U can even phase through walls, although that is a basic capability of Stands.
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 recieving near-lethal wounds from the impact of raindrops, or a lightbulb in Rai's vicinity exploding.)
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, it should be noted that Wonder of U can attack any person who sees the back of its presumed user, regardless of weather or not they hold the intent to pursue. This was demonstrated by Rai, 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 Rai'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.[2]
However, despite Wonder of U's seemingly unbeatable offensive and defensive capabilities, a possible weakness in its defense was noted by Josuke Higashikata following his initial defeat by the stand (and subsequent equivalent exchange treatment.) By remaining completely idle and forcing the stand to confront him, Josuke was seemingly able to bipass the danger of the stand's ability, as no behavior or environemtal factors were present that could be extrapolated into a calamity.
