Jotaro Kujo

Jotaro is a 195 cm (6 ft 5 in) tall[9] and muscular man, who is often described by other characters as attractive.[14] He has dark hair that constantly blends with his hat, a strong jawline, bold eyebrows, and greenish colored eyes.[9] He also bears a mild resemblance to his great-great-grandfather, Jonathan Joestar, and his grandfather, Joseph Joestar when he was young. The superficial theme of Jotaro's attire changes in every JoJo part that he appears in. His trademarks are a visored, ornamented cap, torn at the back and blending with his hair, and a roughly mid-calf-length coat with a standing collar and chains attached.

Jotaro wears a modified trenchcoat-length gakuran 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 pants of very short, sharp flares held up by two thin belts, often differently colored, patterned in a row of alternately colored tessellated triangles. 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 is introduced as a rough, violent 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. He has a habit of muttering "Gimme a break..." (やれやれだぜ, Yare Yare Daze) to himself to express annoyance toward the ordeals and other events that happen close to him, to the point it has become his signature catchphrase.

Jotaro's most noticeable trait is his seemingly aloof nature. He is often satisfied with expressing himself in short phrases. He thinks anyone can tell his emotions just by looking at him, and believes that further effort in portraying how he feels would be a waste of time, making others tend to perceive Jotaro as callous.[9] Related to this, Jotaro is an extremely cool individual, able to keep his composure in even the direst situations. While he was shown to be mildly anxious when something unanticipated happens, Jotaro almost never goes as far as to lose his composure. Jotaro is both fierce and gentle, showing these traits in various scenes, from the fight with N'Doul to the encounter with the D'Arby Brothers. One shining example is how he spared Noriaki Kakyoin instead of killing him outright, even putting his own life on the line just to save the young man from DIO's deadly slavery. Despite refusing to show it explicitly, Jotaro loves his mother and respects his grandfather Joseph.
