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 calamity to anyone who pursues its doctor appearance or works against it.

Appearance
Wonder of U is an artificial humanoid Stand with robotic features. It has a massive torso but thin, tubular arms, with several articulations on its arms and waist. Its entire body is covered with circular ridges that are evenly spaced. It also has long curved blades on its wrists.

Its head has a flattened ovoid shape and a face with two coin-like eyes and circular ridges. 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. The entire face is framed by two pairs of metallic sticks behind its eyes.

Wonder of U's appearance differs depending on who sees it. To the general public, it appears as an elderly hunched man with a monocle and a cane. In its human disguise, the arms and legs are noticeably slimmer than the rest of its body. It wears a bowler hat, dress shoes, a suit, and a scarf speckled by irregular hyphen-shaped slits. Despite its 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. However, it displays the head doctor's face less often to Rai Mamezuku and Josuke Higashikata after they realize that it's a Stand.

Personality
Unlike most Stands in the series, Wonder of U is considerably expressive and holds a calm yet threatening demeanor. It's quite confident in its own abilities, stating that nothing can approach nor hurt it. In fact, it's surprised when Rai Mamezuku manages to get as close as a few centimeters from it. When it's is finally wounded by Josuke's bubbles, Wonder of U is quite shocked that anyone could wound it. The Stand repeadtedly taunts Rai and Josuke into pursuing, notably revealing to Rai that it was the cause of his father's death, pushing him into its ploy. Wonder of U is also perceptive, as it sees through a trap Josuke has been laying for it and quickly analyzes the threat that Josuke could pose because of a surprise injury. Much like the user, Wonder of U takes care to avoid direct combat utilizing rock insects in the fight against Josuke and Rai. As Josuke discovers a new aspect to his Stand's bubbles, Wonder of U decides that the best course of action is simply to escape the hospital.

As the Stand of a Rock Human, Wonder of U asserts its dominance over humans in general, such as when it 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). It 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 the supply notably goads Wonder of U into approaching Josuke.

Wonder of U has a quirk of occasionally stating its name in conversation.

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 Manipulation
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 is a manifestation of the existing calamity energy in the world, being capable of manipulating that energy to its advantage. Due to its nature, Wonder of U is capable of manifesting even after the user is deceased.

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. Objects that come in-contact with Wonder of U can be infused with calamity and trigger the ability when touched.

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. Non-existent things also won't be affected by it since it won't be seen as pursuit.

It is discovered that even after Tooru's death, Wonder of U can act on its own and inflict another calamity on someone else by entering their body, even materialising itself inside. Yasuho theorizes then that the true nature of Wonder of U's ability was to manipulate a "natural law of calamity" meaning a negative energy independant from Tooru's Stand that causes the calamities and exists independantly from Wonder of U.
