Wonder of U

"I am Wonder of U. The flow of things will always lead to calamity."

- Wonder of U

Wonder of U (ワンダー・オブ・) is the Stand of Tooru featured in the eighth part of the JoJo's Bizarre Adventure series, JoJolion, and introduced in the "The Wonder of You" story arc.

It is a sentient Stand that acts as the head doctor of TG University Hospital using the name Satoru Akefu (明負 悟). Wonder of U is capable of causing a disaster to anyone who pursues its doctor appearance or works against it.

Appearance
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.

Personality
Wonder of U demonstrates an antisocial behavior, completely ignoring, 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.

Wonder of U seems rather perceptive, as he sees through a trap Josuke has been laying for him, although it is Tooru who perceives the threat and makes Akefu stay out.

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.

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.

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.

Calamity Generation
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. 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.
