Wonder of U

Wonder of U is the Stand of Tooru, and acts as the final boss of JoJolion.

The Stand's alias, Satoru Akefu is portrayed as the head doctor of TG University Hospital, and 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. After his user Tooru is destroyed by the Higashikata Rock Disease, Wonder of U's ability remains, briefly, as it tries to attach itself to Norisuke Higashikata, but in the end it is destroyed ultimately by Soft & Wet: Go Beyond.

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

Physical Appearance
Wonder of U's most common appearance is its hybrid form that combines its Head Doctor appearance and its full Stand form. It is a black and red robot with red eyes and gold highlights that wears a maroon suit and a yellow scarf. He wears a bowler hat and carries a cane.

Occasional Appearances
In The Wonder of You, Part 16, Satoru Akefu is seen at Mamezuku Rai's father's funeral in a black suit.

His Stand form has a red and blue 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.

When in human form, he looks like an old man with a bowler hat and a brown jacket with a yellow scarf.

In The Wonder of You, Part 9, Satoru Akefu is shown at a lecture at TG Univeristy Hospital without his hat, unobscuring his face.

In The Wonder of You, Part 15, Wonder of U fades between his human form and his Stand form and phases through the walls of TG University Hospital.

In The Wonder of You, Part 21, Wonder of U merges between his Stand and human form, with Satoru Akefu's face popping out of his Stand form's head.

In Go Beyond, Part 2, Wonder of U persists after Tooru's death and attacks Norisuke IV's body. In his form he is no longer humanod, but made of limitless calamity energy.

Powers and Abilities
With Tooru's Stand Wonder of U, he is able to protect himself from attackers by sending "calamities" in their direction. If someone even has the intent to pursue him or the Head Doctor, they will be met with danger. The more they want to pursue them, the more dangerous the thing gets sent their way. The Stand is also capable of merging between a human form and a Stand form, and it appears that those who know its true identity are able to see the Stand form and those who are unaware (or are non-Stand Users) only see him as the Head Doctor. He is able to be countered with Josuke's invisible bubble ability.

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.
 * The fact that he is stated to be 89 years old by Rai is foreshadowing for his calamity ability, as in Japanese the word for "89" and "calamity" both sound the same when said out loud.
 * Wonder of U mirrors the Part 5 Stand Silver Chariot Requiem in that their roles in both their stories are that the main protagonist must pursue them to meet some goal, but the act of pursuit leads to calamities (or in the case of SCR, their Stands attack themselves.)
 * The arc he was introduced in, The Wonder of You, is currently the longest arc in the entire JoJo's Bizarre Adventure series, even beating the page count of Part 1: Phantom Blood by 30 pages, making it longer than all of Part 1.
