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. Its early design features eyes that are decorated with a sun motif, similar to the symbols found on Tooru's outfit. Later chapters change this to plain monocle-like circles.
The Stand's facial features differ depending on who sees it. To the general public, it appears as an elderly-looking man with a monocle and 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. Those who are aware of its ability see its true face.[3]
Once it is revealed that Satoru Akefu and Wonder of U are the same entity, Wonder of U keeps Satoru's suit and hat, and his appearance randomly switches between that of Satoru or his true form.
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.

Identity Assumption
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.[2]

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,[4] 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.[5]
Calamity Generation
Wonder of U descends on Josuke and company
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.[6] 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.[5]

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,[7] 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.[8] 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.[7] 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.[5] This is further expanded upon by Wonder of U, stating that there is a "flow" of things that always results in calamity[2] which was previously hinted at by Tooru.[9]
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.[1] 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.
The easiest time for a traveler to run into misfortune on their long, long journey is right before they return home. Soon this long, long journey of ours will conclude... I will hold onto the New Locacaca, and then we can all head home.
The flow of things... This is about you standing up from that chair. Perhaps you'll stand up intending to pursue me. I am Wonder of U. The flow of things will always lead to calamity.
Josuke. Just now, you were standing up... in turn, you extended the joints of your arms and legs. Oh dear, it seems it's too late. You were already stung by as many as four stingers. Does your eye still work? What would you think if I told you this was the last time it will? Dododo De Dadada usually aims for the throat. The asbestos will make quick work of plugging up your respiratory tract and suffocating you.
Umm... so, personally... this is the first time this has happened, so I'm a bit surprised. Only a centimeter away... I mean, I don't think there's ever been someone who's gotten that close to me... without a, you know... calamity occurring... I'm not really... not really quite sure what happens at one centimeter away... 'cause it's my first time. I don't really understand it either. Seriously. But in the flow of calamity... there's nobody who can attack me. Not a single person. That, I know for sure. Wonder of U.
While its name was revealed in the story arc Endless Calamity, Wonder of U's name was hinted from the name of the story arc it was introduced in, The Wonder of You.
