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.
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.
Thats just the design of his hat its not actually stuck to jotaros head.
Strength: Athletic Class Jotaro himself is quite strong without his stand, possessing the ability to send someone flying with a single punch.
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.
In Stardust Crusaders, Jotaro was 17 years old. 10 years later in Diamond is Unbreakable he was 27, and in Vento Aureo he was 29, making him 40 at the end of Stone Ocean.
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.
Khnum is truly the weakest Stand in all of JoJo's Bizarre Adventure. Its ability is Transfiguration, allowing its user to take the appearance of another person. The problem is that Khnum gives its user no additional abilities.
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.
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.
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.
Iggy gives back Jotaro's lost hat, shortly earning his trust until Jotaro realized that Iggy put coffee gum inside it.
One of the strongest characters in the series, Jotaro was nerfed in Part 6.
According to Part 5, it's just art style, as it shows Jotaro in Egypt with Polnareff, and he's skinny.
Arguably the single most powerful Stand in the franchise, Gold Experience Requiem resets anything it touches to “zero.” More importantly, its use in the series shows that it can force someone to relive their deaths over and over again. Even with Star Platinum: The World, Jotaro doesn't stand a chance.
Stats. The Stand named 'Survivor' is the 'weakest'.
There is no doubt that DIO is the most iconic villain in the series, and one of the few characters who have appeared in more than one part. DIO's malevolence and dark charisma turned him into a fan favorite. In terms of power, he lacks in a few departments but is still a menacing force.
3 STANDS ARE BETTER: Their Powers Are More Extreme
Hamon makes the user stronger, but it hardly works on any level beyond physical strength.
Jolyne awakened her Stand after her finger was pierced by an amulet, which was actually a part of the Stand arrow's head. It is a close-range Stand, which is very strong physically.
Jotaro abandoned Jolyne when she was young out of concern for her safety, worried that people associated with Pucci would come to find him and seek Jolyne as a way to get to him. Jolyne comes to understand this aspect of her father, and how he cared about her from a distance without getting involved.
In Jotaro's prime, the ability could last up to 5 seconds, but decreased over time due to lack of combat. Ten years after its initial use, Jotaro is only able to stop time for half a second, but intuitively extends it to 1–2 seconds throughout the later half of Diamond is Unbreakable.
Not cool, Jotaro, she raised you practically on her own. Just to be clear, Jotaro does love his mom.
