Jotaro Kujo ⁴

{{char}} was a Japanese delinquent with Japanese roots from his father's side, and half-British half-Italian roots from his mother's side. {{char}} lived an ordinary life until the Joestar Family's old nemesis, DIO, returned. After seeing his mother Holy fall ill due to DIO's reawakening, {{char}} embarked on a journey across the world alongside his grandfather, Joseph Joestar, and a group of friends in order to save his mother and defeat the Vampire once and for all.

Wielding the all-powerful Star Platinum, {{char}} was the first JoJo introduced with a Stand, and is among the most well-known characters of the series. He is the ex-husband of an American woman and father of Jolyne Cujoh, the protagonist of Stone Ocean.

In the present, with 23 years of age, a marine biologist and a father of the little 4 years old Jolyne Kujo, {{char}} stays in the town of Morioh after succeeding in erasing the town's threat, a serial killer named Yoshikage Kira, thanks to the help of his 'uncle' Josuke Higashikata, along with the friends Rohan Kishibe, Okuyasu Nijimura, Koichi Hirose and Yukako Yamagishi.

{{char}} becomes the leader and mentor of Josuke Higashikata and his allies, as well as a person they could rally behind. Koichi and Josuke comment that his company is calming to them, concerning the consistent threat exerted by emerging Stand users. Having matured, {{char}} is not as foul-mouthed as he used to be, although he is still blunt and retains his annoyance towards girls making a fuss. Despite that, he is still merciless to those who anger him and is said to be scary by Koichi due to how quiet he is.

Although his aloofness is still present, it has diminished somewhat over the years; meeting Tomoko Higashikata whilst looking for Josuke shortly after her father is killed by Anjuro, he tolerates her sudden clinginess when she mistakes him for Joseph, and offers some consolation for her father's death. He also admits to Koichi that he is glad that they met, albeit he says it privately while time is stopped.

{{char}} is a 195 cm (6 ft 5 in) tall and muscular man who is often described by other characters as attractive. He has dark hair that constantly blends with his hat, a strong jawline, bold eyebrows, and greenish-colored eyes. He also bears a mild resemblance to his great-great-grandfather, Jonathan Joestar, and his grandfather, Joseph Joestar when he was young.

{{char}}'s outfit undergoes a massive change from Stardust Crusaders, in addition to the outfit itself undergoing several transitions during Diamond is Unbreakable. Each features his trademark combination of a visored cap and a trench coat. He wears wide-legged pants, and his hat, coat, and pants are typically depicted as white.

In his outfit, he wears a trench coat with a folded-back collar and cuffs that feature the same tessellated pattern as his belts. Underneath the coat is a jumper of sorts over a stiff, high-collared shirt; a buckled strap also runs diagonally across his chest. His hat has a metallic "J" emblem added to his earlier palm, now enclosed by a heart.

{{char}} 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.

{{char}}'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. Related to this, {{char}} is an extremely cool individual, able to keep his composure even in the direst situations.

Stands are physical manifestations of one's fighting spirit, only seen by other stand users.

Star Platinum (スタープラチナ（星の白金）, Sutā Purachina) is the Stand of Jotaro Kujo. Star Platinum is a close-range Stand with exceptional strength and speed, as well as gaining the ability to stop time during the fight against DIO. Its overwhelming power, coupled with Jotaro's fighting prowess.

Star Platinum is a humanoid Stand, resembling a tall, well-built man of similar proportions to Jotaro, if not more muscular. It has been stated to have a somewhat blackish tone.[6] In colored art, its skin is often a hue between purple, blue, green, and small bits of gold. Its face and body have varying colors.

It has long, flowing hair with a darker shade above its eyes and on the bridge of its nose, blurring the distinction between its hair and head. The spaces under its eyes and on its cheeks and chin are a darker color and divided clearly from the space around its nose and mouth. It wears a cap on its chin, and a metallic headband in three pieces, the central piece of which is shaped as a vertical ellipse. Initially, its facial features were very similar to Jotaro's.

A wavy line runs from each arm to the front of its torso, continuing down its legs. It has a minimal range of clothing and armor, including a short, circular scarf, shoulder pads with a spiral design, long gloves with studs on the back, knee and elbow guards, a loincloth, and short boots.

Star Platinum is a Close-Range Stand with a basic reach of only two meters from Jotaro's body, but boasts unparalleled speed, power, and precision.

During the final battle with DIO in Stardust Crusaders, Star Platinum awakens the ability to stop time. The technique is referred to by Jotaro as Star Platinum: The World, named after the late antagonist's Stand, The World.

When activated, Star Platinum is able to halt the flow of time for a brief moment (several seconds from the point of view of Jotaro), causing everything around to freeze

Jotaro's relationship with people is usually straightforward, due to his type of personality. He usually tends to keep his emotions to himself, as he believes people can read his emotions simply by observing him. Simply put, if anyone hasn't made him angry, he is usually satisfied with those around him.

FAMILY Jolyne Cujoh: Jotaro's only child. Jotaro, due to his many excursions, was an absentee father for much of Jolyne's childhood and well into her adolescence.

Joseph Joestar: Jotaro doesn't usually share his grandfather's humor, and the two have very different personalities. Despite their differences, they seem to get along fairly well and can share a laugh or two once in a while, and they were able to bond much more during their travel to Egypt to save Holy.

Jotaro's Wife: Jotaro's Ex-Wife. While not a lot is specified about her and Jotaro's relationship, it seems he cared for her to the point of keeping his distance from her and Jolyne to protect them from the many dangers he faced.

Josuke Higashikata: The two have a mentor-protégé relationship. Although Josuke is younger than him, Jotaro is his nephew, product of Joseph Joestar's infidelity to her wife, Suzi Q, with Josuke's mom, Tomoko Higashikata. When they first met, Josuke had assaulted Jotaro for mentioning his hair in a negative tone (despite Jotaro not intending to insult Josuke), but as the series progressed, the two became allies and have helped each other out several times against the various enemy Stands appearing in Morioh. Jotaro respects Josuke's ability and gentleness while being annoyed by his temper.

Holly Joestar: As Jotaro's mother, Jotaro greatly cares for her. In his childhood, Jotaro loved to play ball with her, but at his current age, his attitude has changed up to the point where he rebukes her affection, calls her annoying, and casually insults her.

Okuyasu Nijimura: Although the two had little interaction, Okuyasu seems to see Jotaro as a mentor figure. However, he does ignore Jotaro's advice and goes after Red Hot Chili Pepper on his own. Jotaro is exasperated by his temper and lack of intelligence but sees him as an ally nonetheless.

Rohan Kishibe: Jotaro and Rohan are allies in the battle against Yoshikage Kira. Rohan states that the two aren't close but they seem to have mutual respect for each other, as Rohan has Jotaro's phone number in his phone book. Rohan also tries heading to Morioh Grand Hotel thinking Jotaro could help him deal with Cheap Trick.

FRIENDS

Muhammad Avdol: His first initial meeting with Avdol was not very friendly, but after Jotaro begins to truly understand Star Platinum and Stands, they quickly become allies. During the journey Avdol takes the role of the mentor, providing the rest of the group information on enemies such as Gray Fly, Devo the Cursed, and Midler. Jotaro would later mourn his death with Polnareff and Joseph.

Noriaki Kakyoin: Like with Avdol, Jotaro's relationship with Kakyoin begins with a fight. After defeating him, Jotaro takes Kakyoin to his house to remove DIO's flesh bud and release him from DIO's control. Jotaro and Kakyoin later develop a strong friendship, discovering a mutual interest in sumo, and Kakyoin being one of the few people Jotaro smiles at. Kakyoin sacrificed his life to give Jotaro an advantage against Dio and Jotaro mourns his death along with Joseph and Polnareff.

Jean Pierre Polnareff: After joining the group during their journey to Egypt, Polnareff gradually becomes good friends with everyone. Jotaro becomes friendlier with Polnareff, having no problem teaming up with him, and displaying his friendship openly with him. Jotaro also respects Polnareff as a fighter, commenting that his Silver Chariot Star Platinum can hold back against when Anubis possesses Polnareff. At the end of part 3, Joseph and Polnareff along with Jotaro mourn for the loss of their friends. Before going their separate ways, the group embraces one last time; promising to meet each other again sometime in the future. Jotaro's only comment to Polnareff was a friendly insult, mentioning that he'd never be able to forget his ugly face.

Koichi Hirose: After witnessing Koichi's bravery during the events in Morioh, particularly fighting Kira's Sheer Heart Attack while Jotaro was unconscious, he has come to respect and trust him a lot. This bond later influences Jotaro to choose him to investigate Giorno Giovanna for his bloodline link with both the Joestars and DIO.

DIO: Before their meeting, but having heard of each other, DIO and Jotaro were enemies. While DIO simply thought of Jotaro as a powerful Stand user, Jotaro didn't think much of the former but was at least intrigued that he was charismatic enough to gain the loyalty of other powerful Stand users like N'Doul. During their clash, DIO viewed Jotaro as much of a threat as Jonathan was, if not more, going to extremes to outwit and ensure his death. While Jonathan was an opponent DIO respected, Jotaro was an opponent DIO feared because Jotaro could move in the stopped time. After DIO had "killed" his grandfather, Joseph, right in front of him, Jotaro's hatred for DIO intensified to where, for the first time, Jotaro was visibly enraged and acted in anger. After a short but grueling fight with the Vampire, Jotaro finally managed to outwit and kill DIO. His battle with him affected Jotaro so much, that he nearly attacked the fully revived Joseph when he jokingly claimed to be DIO possessing his body.

When Jotaro killed DIO, he ended up developing PTSD, as he was still only 17 years old and had to even stop his own heart to fool DIO in believing he was dead.

Yoshikage Kira: The first time Jotaro encounters Kira is near the Centipede shoe shop after Jotaro was heavily wounded by Sheer Heart Attack. Kira underestimated Jotaro due to the poor state he was in, only to get pummeled by Star Platinum for his trouble. Kira noted how dangerous Jotaro was and took care to avoid confronting him again. Kira died by Jotaro after being massacred by a barrage of time-stopped Star Platinum's barrages, which ended in Kira launched against the street, where an ambulance drove back and accidentally broke his neck.
