Wonder of U

Wonder of U is an artificial humanoid Stand with robotic features. It has a large 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 more 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 Toru'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 in its disguise; meanwhile, to those who are aware of its ability, its true face appears. The disguise is depicted as Satoru Akefu, an elderly man with a stocky build said to be 89 years old. The disguise has a thin furrowed face with prominent cheekbones, sunken eyes, a large nose, and thick white hair. The disguise's most notable features are a beard styled into multiple short spikes and a monocle on its right eye. Much like the Stand's subordinate Wu Tomoki, the hair on the sides of its head is composed of many spheres.↗↗↗↗↗

Wonder of U displays a distinct personality, though it is ambiguous how much of its behavior stems from the Stand itself versus its user, Toru. The two share sensory information and overlapping thoughts, with Wonder of U obeying Toru's commands such as retreating and prioritizing its safety, as well as Toru directly speaking through it. However, the two have distinct speech patterns. Toru speaks casually and uses the youthful personal pronoun boku (僕), while Wonder of U consistently uses the formal watashi (わたし) and addresses others with the second-person pronoun kimi (君), keeping in line with its disguise as an older man. The Stand frequently refers to itself as "Wonder of U".↗↗↗↗↗↗↗↗↗↗↗

When assuming the identity of the head of TG University Hospital, "Satoru Akefu" acts the part of a prestigious and respected elderly doctor. During a presentation for Locacaca 6251, it carries itself like a proud researcher unveiling the miracles of a new form of medicine. The "Akefu" personality is cordial, politely exchanging business cards with the journalist Taoka and offering him an examination for his acne. However, there are moments where the nature of this disguise slips; before meeting Taoka, the hospital director is seen standing lifelessly in a corner, staring blankly at a wall before suddenly snapping into its conversational persona.↗↗↗↗

Human Disguise

Wonder of U has the unique ability to take on a human form, which unlike most Stands, can be seen by non-Stand users. This allows Wonder of U and Toru to lead a double-life under the assumed identity of Satoru Akefu, the director of TG University hospital. Consequently, Toru has access to both the hospital resources and presumed credentials needed to carry out his role as the shadowy mastermind behind the Locacaca Organization.↗↗

Long-Range Illusion Projection

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 Toru'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 cannot be seen by other members of the Higashikata family, while another vision of the Stand can be seen by a large audience attending the hospital director'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 allows it to manipulate a "natural law of calamity," which is a form of negative energy independent from the Stand. It is automatic and functions at long range, making it extremely dangerous, as there is little defense against it.↗↗

Wonder of U's ability can be activated on any person who pursues it or its user. While Wonder of U's ability is active, targets will experience horrible developments referred to as calamities (厄災, yakusai). 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).↗

Post-Mortem Persistence

More particularly, the post-mortem form of "Wonder of U" is a manifestation of the natural law of calamity, a natural part of the world's logic that cannot normally be erased. Despite this, Go Beyond is able to defeat Wonder of U's post-mortem form, turning it to dust and seemingly erasing it from the world for good.↗↗

Medical Experience

Pretending to be a physician in charge of an entire hospital, it can be inferred that Wonder of U is knowledgeable on both general medical knowledge, as well as medicinal applications of the Locacaca fruit.↗
