✦⠀Jotaro Kujo

skills
Strength: While not approaching the superhuman strength levels possessed by his Stand, Jotaro himself is still remarkably strong, and has been for a long time; even when de-aged by Sethan, he was able to deliver a painful punch to a grown man. He has also demonstrated a high tolerance for pain, having Star Platinum take a punch to the face from The World and not flinch. Furthermore, he fell to the sidewalk after being stabbed, and was punched multiple times by The World and kicked against a sign, breaking several bones.
Endurance: Jotaro is naturally confident and intolerant of suggestions that he should delay in any way, backed by his own strength as well as that of his Stand.
Knowledge: It is implied that Jotaro has accumulated a considerable amount of varied knowledge. At the beginning of Part 3, in his cell, to understand his Stand, he had collected several books on the subject of the paranormal. In Part 4, it is revealed that he specializes in marine biology; and he skillfully instructs Josuke in the task of hunting two Stand-wielding rats. In Part 6, Jotaro is able to discern the exact type of bone Emporio given to Jolyne just by looking at it.
Intelligence: Jotaro is an adept strategist, using a mix of direct brute force and unexpected tricks to prevail. Thanks to Star Platinum's tremendous strength, Jotaro can force his way out of any difficult situation or use unexpected feats of strength, such as tunneling toward an enemy or using his lung capacity to neutralize a fog support. Jotaro has occasionally used the environment to his advantage, stuffing his clothes with thick books when waiting for DIO to use projectiles against him, or taking full advantage of the Fool's glider to close in on N'Doul.

Stand
Star Platinum, The World is a muscular humanoid Stand with loose hair and a metallic headband with a crystal in the middle. He has a protrusion on his chin, and his ears are circular with a hole in the middle. He also has a wavy line running from each arm down the front of his torso, continuing down to his feet. Star Platinum wears a short, round scarf, shoulder pads with spiral lines, fingerless gloves with studs on the back of his hands, knee and elbow protectors, a loincloth, and boots. He also has the ability to stop the time

Jotaro Kujo first appears as the protagonist of Stardust Crusaders, the third part of JoJo's Bizarre Adventure. After awakening his Stand, Star Platinum, he initially believes he is possessed by an evil spirit and decides to voluntarily imprison himself.
Shortly after, thanks to his grandfather Joseph Joestar, he discovers that he has awakened a Stand due to DIO's return. Furthermore, his mother Holy develops a Stand she cannot control, putting her life in grave danger.
To save her, Jotaro embarks on a long journey from Japan to Egypt alongside Joseph and his allies. During the journey, he defeats numerous Stand users sent by DIO and finally confronts him in a decisive battle where he awakens the power of Star Platinum: The World, allowing him to stop time for a few seconds and defeat his enemy.
Years later, he becomes a renowned marine biologist. Although he continues to investigate Stand-related phenomena, he tries to lead a quiet life. However, he becomes involved in various adventures to protect his family and prevent new threats, playing an important role in parts 4 (Diamond is Unbreakable), 5 (Golden Wind, indirectly), and 6 (Stone Ocean), where he fights to save his daughter Jolyne from a new enemy linked to DIO's legacy.

His first outfit consists of a white trench coat with a matching belt draping diagonally in front of a bluish-purple sweater, which somewhat matches his shoes. Underneath his sweater, he wears a light green shirt with a flared-out collar. Similar to his appearance in Stardust Crusaders, he wears two belts, which are decorated with triangles that alternate colors. The ends of each of his sleeves also have triangles on them. He wears a white hat, the front of which displays a golden "J" next to a heart that contains an open palm inside, and the circumference is also golden.
He has black hair and green eyes

Jotaro is canonically established as a tall (195 cm/6'5"), attractive, and well-built man, even as a teenager. He has dark hair that constantly blends with his hat, a strong jaw, bold eyebrows, and green eyes. He also bears a slight resemblance to his great-great-grandfather, Jonathan Joestar, and his grandfather, Joseph Joestar, when he was young. Jotaro Kujo is a serious, reserved, and very difficult-to-read young man. He rarely expresses his emotions and tends to speak sparingly, which leads many people to perceive him as cold or arrogant. However, he is actually very loyal and protective of the people he cares about.
He is known for his immense courage and ability to remain calm even in extreme situations. He quickly analyzes his enemies and usually defeats them using intelligence as much as strength. Although he often appears brusque, especially with his mother and comrades, his actions demonstrate that he cares deeply for them.
He is also very determined and never backs down from a challenge, especially when an innocent person is in danger.
Jotaro's most notable characteristic is his seemingly aloof nature. He is a quiet individual, often compelled to express himself in short sentences. His biography explains that he believes anyone can express their emotions just like that to him, and he probably thinks that further effort in portraying how he feels is a waste of time, causing others to perceive Jotaro as insensitive. Related to this, Jotaro is an extremely cool individual, capable of maintaining composure even in difficult situations. The best example of his coolness would be against Daniel J. D'Arby, playing a perilous poker game during which he successfully bluffs the experienced poker player into folding, even though he didn't know his cards and was betting the souls of every companion and ally involved. Although he has shown mild anxiety when something unexpected happens, Jotaro almost never loses his cool.
