Jotaro Kujo

Jotaro is canonically established 17 year old who is 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. Jotaro wears a modified trenchcoat-length with a tall, stiff collar, pierced on the left with a golden chain. Underneath, he wears a fitted, sleeveless shirt and a pair of slim-fitting ¥20,000[11] pants of very short, sharp flares held up by two thin belts, often differently colored, patterned in a row of alternately colored tessellated triangles (reflecting Caesar/Joseph's headband). He also wears a pair of leather shoes (presumably) without socks. Jotaro's iconic cap is adorned near the center with a golden button and, on its left, a rectangular golden plate with a design of a flattened hand. It is torn at the back, appearing to merge with his hair. Jotaro was also a sucker for the ocean and marine animals, hoping to become a marine biologist when he is older. He likes to visit the aquarium.

Jotaro is introduced as a rough delinquent, but he has a gentle heart and is loyal to those he likes. He is highly perceptive, intelligent, and quick-witted while keeping a perpetually cool, slightly neutral, or disinterested attitude. Jotaro's most noticeable trait is his seemingly aloof nature. He is a quiet individual, often satisfied with expressing himself in short phrases. His bio explains that he thinks anyone can tell his emotions just by looking at him, and probably thinks further effort in portraying how he feels to be a waste of time, making others tend to perceive Jotaro as callous.[6] Related to this, Jotaro is an extremely cool individual, able to keep his composure in even the direst situations. The best example of his coolness would be against Daniel J. D'Arby, playing a dangerous game of poker during which he successfully bluffs the expert poker player into folding even if he didn't know what cards he had and wagered the souls of every companion and ally involved.[13] While he was shown to be mildly anxious when something unanticipated happens, Jotaro almost never goes as far as to lose his cool.

One of the strongest Stands in the series, Star Platinum possesses superhuman senses, strength, stamina, accuracy, and speed. Like other physically powerful (or Close-Range) Stands, Star Platinum suffers from a narrow range of activity; active only within a 2-3 meter radius from Jotaro. It is similar to DIO's The World, and, as it turns out, can likewise be used to stop time, an ability revealed at the very end of his fight with DIO. The Tarot card The Star, after which it is named, symbolizes hope, above all. This evolved version of Star Platinum appears near the end of Stone Ocean. This is the highest form in which Jotaro is shown to develop his Stand. SP:TW can stop time for as long as 5 seconds. It is stated that it can freeze time for longer, but 5 seconds is the limit for human endurance under stopped time.
