In the series Jotaro on 3 occasions takes off his hat and you can easily see that it isn't hair but actually is ripped due to wear and tear because he gets into lots of fights.
The answer, then, seems to be that his hat is ripped at the back -- part of his stereotypical Japanese delinquent aesthetic -- and its shape and color just happen to blend seamlessly with his hair, creating the illusion that they are one and the same.
According to Part 5, it's just art style, as it shows Jotaro in Egypt with Polnareff, and he's skinny.
One of the strongest characters in the series, Jotaro was nerfed in Part 6.
The small golden hand on Jotaro's hat actually has a double meaning first it's a symbol of abhayamudra. Essentially a symbol for fearlessness and protection which pretty much defines Jotaro. And the second meaning is the logo of lucky land communications.
It was based off of which team had the most wins, the number person (even he was in second place team, he carried the team) was Jotaro Kujo, with 20 wins, he probably needs that second belt to cary his team.
Strength: Athletic Class Jotaro himself is quite strong without his stand, possessing the ability to send someone flying with a single punch.
The reset caused by Pucci's Made In Heaven made it possible for Araki to wrap up the story of one universe and then start anew with an entirely different universe. So, keeping Giorno out of action was the sensible thing to do as it allowed Araki to try out new things.
Time Stop. When activated, Star Platinum is able to halt the flow of time for a brief moment, causing everything around him to appear frozen in place. During this time-lapse, Jotaro is able to interact with any object or person within his range.
Also if you are wondering why Jotaro has 5 seconds and not 2, it's because when Dio got Joseph's blood, Jotaro got mad. It's known that how long the time stop is depends on the user's stamina. Dio is a vampire, so he has lots of it.
Out of all the Jojo protagonists, Jonathan stands out in terms of nobility, inspiring even Speedwagon, a former thug. Another notable feature of Jonathan is his undisputable physical strength, exceeding any Joestar protagonist.
In the hierarchy of the Pillar Men, Kars is number one. He is the oldest of the surviving Pillar Men, and although his specific height is never mentioned, Kars is presumably the largest and strongest of the Pillar Men.
The group takes cover behind a rock and deduce that since Sun is so large, the Stand user must be close. Everyone but Joseph begins laughing, and he believes they are losing their grip because of the heat. Kakyoin reassures him that they are laughing because they notice two identical rocks close by.
Stardust Crusaders
They explain that Jotaro's "evil spirit" is actually a manifestation of his fighting spirit, called a Stand, and reveal that they possess Stands as well. Joseph explains that the sudden appearance of their Stands is caused by the nemesis of his grandfather, Jonathan Joestar: DIO.
How did Jotaro die? In Part 6 of Stone Ocean, he was killed by Pucci as he attempted to protect his daughter, Jolyne from him. His attachment to his daughter stopped him from killing Pucci and putting an end to their battle.
Throughout Stardust Crusaders and well into Diamond is Unbreakable, Star Platinum proves to be one of the most powerful Stands, whether it's through its crushing melee force, its pinpoint accuracy, or even its legendary ability to stop time.
Wonder of U has a case of being the strongest Stand in the series. It is a sentient Stand that can function on its own. Wonder of U possesses a number of abilities that make it an extremely dangerous stand. It can create illusions of itself, which can confuse the target.
Star Platinum Requiem is a requiem version of Star Platinum that was formerly obtainable through an Easter Egg, but that method was removed. It was formally obtainable from Stand Arrows. This stand has an identical moveset to and basic attack speed as Star Platinum: The World, but has higher damage.
Pucci's stand, Made in Heaven, has the ability to speed up time fast enough to surpass Time Stop, meaning Pucci can't be affected by Jotaro even when he stopped time. However, Jotaro is more powerful than Pucci on a physical level, giving him an advantage when both stands have no time powers.
The JoJoLands (stylized as The JOJOLands) is a Japanese manga series written and illustrated by Hirohiko Araki, and the ninth part of the larger JoJo's Bizarre Adventure series. Set in the U.S. state of Hawaii in the 2020s, it follows Jodio Joestar, a teenaged gangster intent on becoming wealthy.
Giorno Giovanna is the first Gio Gio born in the Giovanna bloodline, being borned from his gay, vampire father, Dio Brandito, no Bandito. Gio is a high-functioning autistic manchild and nazi.
Joseph Joestar is one of the weakest Joestar characters in the series. His stand is not all that impressive since Purple Hermit only produces thorny vine-like extensions that can bind someone.
But is there any connection between Hamon and Stands? Hamon and Stands do not share a direct connection. While Hamon is an advanced development and manipulation of the human breath, Stands are the product of an organism's mental fortitude activated naturally or through a catalyst.
Remember when Joseph and Avdol meet Jotaro in jail and told him that Stands were a manifestation of life force? That's the same principle of hamon and that's the reason DIO isn't immune to them.
