Jotaro is introduced as a rough 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.
Jotaro's nerves of steel destabilize D'Arby
Jotaro's most noticeable trait is his seemingly aloof nature. He is a quiet individual, often satisfied with expressing himself in short phrases. His bio explains that he thinks anyone can tell his emotions just by looking at him, and probably thinks further effort in portraying how he feels to be a waste of time, making others tend to perceive Jotaro as callous.[6] Related to this, Jotaro is an extremely cool individual, able to keep his composure in even the direst situations. The best example of his coolness would be against Daniel J. D'Arby, playing a dangerous game of poker during which he successfully bluffs the expert poker player into folding even if he didn't know what cards he had and wagered the souls of every companion and ally involved.[13] While he was shown to be mildly anxious when something unanticipated happens, Jotaro almost never goes as far as to lose his cool.
Abilities
Stand

One of the strongest Stands in the series, Star Platinum possesses superhuman senses, strength, stamina, accuracy and speed. Like other physically-powerful (or Close-Range) Stands, Star Platinum suffers from a narrow range of activity; active only within a 2-3 meter radius from Jotaro.
It is similar to DIO's The World, and, as it turns out, can likewise be used to stop time, an ability revealed at the very end of his fight with DIO.
The Tarot card The Star, after which it is named, symbolizes hope, above all.

This evolved version of Star Platinum appears near the end of Stone Ocean.
This is the highest form to which Jotaro is shown to develop his Stand. SP:TW can stop time for as long as 5 seconds. It is stated that it can freeze time for longer, but 5 seconds is the limit for human endurance under stopped time.
Early Life (1971-1987)
Jotaro as a toddler.
Much of Jotaro's youth was that of a normal Japanese child.
He participated in many activities, including playing ball as a toddler, running track as a young boy and attending school. Throughout his childhood, he was supported and supervised by his mother, Holy, while his father Sadao was constantly on tour.[2] The details of Jotaro's eventual shift into delinquency by the age of 17 are unknown.
