Wonder of U (ワンダー・オブ・
He 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 the doctor or works against him.
Wonder of U is an artificial humanoid Stand with a mostly black body. He has a doll-like body, with a massive torso but thin, tubular arms. Each of his articulations, from the waist to the elbows, is a pivot joint. His body is covered with light circular ridges that are evenly spaced. He also has a long curved blade at each wrist much like Kars.
His head has a flattened ovoid shape, still black with the same ridges around its head. Moreover, he has a reverse U-shaped ridge framing his 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. His arms and legs are noticeably slimmer than the rest of his body. He wears a dark-colored hat and suit, along with a lightly colored scarf with a pattern of irregular "-" shaped slits cut into it. He 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 him. Wonder of U remains calm as his automatic power allows him to get rid of any potential enemy before they can even harm him. Wonder of U is also perceptive, as he sees through a trap Josuke has been laying for him.
Wonder of U's ability is an automatic one that functions at long range and is extremely dangerous because there is little defense against calamities.
Wonder of U's ability can be activated on any person who has looked at his back in an attempt to chase after or confront him or otherwise moves toward him. While Wonder of U's ability is active, targets will experience various instances of conflict which seemingly play out in the most devastating way imaginable. These calamities often involve an affected person repeatedly colliding with objects in their environment, resulting in far greater injury than is possible under normal circumstances. The ability's trigger is sensitive, as Mitsuba simply questioning the presence of Wonder of U was enough to activate it. The range of the ability is unknown, but it appears to be extremely large, as Josuke and Mamezuku were affected despite being nowhere near Wonder of U's whereabouts.
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.[1]
Once a person has been targeted by Wonder of U, any attempt to pursue him will cause it to manifest and re-activate the ability, regardless of the target's distance. The threshold for re-activation is extremely sensitive. Wonder of U's ability was able to re-activate from Josuke merely intending to go after its user. It's also possible for Wonder of U to manually re-activate his ability on a target by finding them and having them look at him from behind, as demonstrated on Mitsuba Higashikata.
In JJL Chapter 94, Mitsuba describes that the Stand's ability causes unforeseen bad things to happen again and again when someone see Wonder of U's back, making them feel like misfortune is chasing them down. Rai Mamezuku theorizes that the head doctor everyone keeps seeing from the back is actually the Stand itself, and that the user is hiding. Moreover, he theorizes that the Stand is made of "calamity energy", whose power is directly related to the actions of the victim. For instance, Mamezuku's cellmate tried to stab Rai with a knife, but instead stabs himself because of the karmic retribution cast by the Stand.
In addition to this, Wonder of U is able to create illusions which can be sent after a specific target. Firstly he can disguise itself and take on the appearance of a human, allowing him to interact with ordinary humans. Secondly, Wonder of U can create projections of himself. 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 Wonder of U will also be attacked.[1] Wonder of U can even phase through walls, although that is a basic power for Stands.
