Wonder of U

Wonder of U (ワンダーオブユー Wandā Obu U) is the Stand of Tooru, featured in Part 8: JoJolion.

The Stand's alias, Satoru Akefu (明負 悟 Akefu Satoru) is portrayed as the head doctor of TG University Hospital, and presumed mastermind of the Locacaca Organization. He is an elusive figure with almost no public presence despite being in charge of a major institution of medicine.

It was theorized that Akefu was a Stand User but it is revealed that he is the Stand itself. Akefu's power is to cause calamity to anyone who pursues him or works against him. He is the stand of Tooru.

Appearance
The true form of Satoru Akefu is that of a Stand. It is an artificial humanoid Stand with a mostly black body. Akefu 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 evenly spaces. 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 two pair of round mechanical eyes that are a throw back to Akefu's monocle. The eyes are decorated with a sun motif, similar to the symbols found on Tooru's outfit.

Powers and Abilities
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.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. 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.

Trivia

 * Wonder of U's name was hinted from the name of the story arc it was introduced in, The Wonder of You.
 * The covers of Ultra Jump 2020 Issue #5, JJL Volume 23 and JJL Chapter 96 all feature imagery of multiple instances of Satoru Akefu levitating in the sky, bearing resemblance to the work Golconda of Belgian artist René Magritte.
