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.[13] He has dark hair that constantly blends with his hat, a strong jawline, bold eyebrows, and greenish colored eyes.

Jotaro wears a modified trenchcoat-length gakuran/tsume-eri 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[15] 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. While they are first shown as being completely separate but slightly torn.

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). His movements are minimal, and he's a quiet individual.

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. Jotaro is both fierce and gentle. Jotaro loves his mother and respects his grandfather Joseph. Jotaro's impetus for going to Egypt is Holy's life being put in danger by DIO's Stand. Jotaro also has a soft spot for children and is noticeably more tolerant and protective toward them.

Jotaro hates people who hurt women or children in a fight, even if the woman or child in question is evil, and will be especially violent toward them. Furthermore, nagging girls chasing him (both at his school and throughout his journey) annoy Jotaro, who ignores or rudely drives them away, particularly when they begin to fuss or bicker.

Moreover, Jotaro is blunt and foul-mouthed, having no problem being insolent towards his mother or any other authority figure.[5] The teenager favors witty one-liners, often ridiculing whoever is the target of his quips and offering absurd reasons for his feats.

Jotaro is interested in a large range of subjects, such as sumo or the TV series Columbo, from which he claims to have acquired his deductive skills. Ironically, Jotaro is one of the few who can appreciate Calcutta's atmosphere, which shocks Joseph.
