Jotaro is a delinquent who lives in Japan. He is rather aloof, and the reason for this is unknown as he had a good childhood. One day, Jotaro turned himself into the police after a fight, believing himself to be possessed by what he thought was an evil spirit. Even after he was allowed to leave prison, he chose to stay until his grandfather Joseph Joestar arrived with his friend, Muhammad Avdol. Joseph explained Jotaro's Stand powers and afterwards, he left the prison with Joseph and Avdol. Sometime later, Jotaro's mother, Holy, fell ill as she could not control her Stand and it was stated by Avdol that she would die within 50 days unless she was cured. The only way to do this was to kill the person who awakened the Stand, DIO. Jotaro, along with Joseph and Avdol set out to Egypt for DIO, making some allies along the way. Of course, DIO was not going to make things easy for the group.
Powers and Abilities
- Star Platinum: Star Platinum is the name of Jotaro's Stand. A Stand is the personification of one's life energy and they exist to protect their user. Stands take many appearances and their abilities differ. They are only visible to living beings that possess one. Star Platinum takes a natural humanoid appearance and it is classified as a Close-Range Stand, which means it excels at dealing damage at close-range. It is most known for throwing rapid punches which are useful for destroying objects or giving a good old beat down.
- Superhuman Strength: Star Platinum has immense strength, allowing it to perform feats than no average human can do. Its punches can effortlessly destroy solid objects and it can also lift heavy objects, such as vehicles.
- Superhuman Speed: As well as strength, Star Platinum possess superhuman speed and reactions. It can throw thousands of punches in a matter of seconds and can catch bullets, even at point blank range. It is also able to move faster than the speed of light
- Self-Preservation: Star Platinum is able to protect Jotaro at times when he is not aware of danger or cannot do anything himself to prevent further harm. For example, it was able to prevent Jotaro from shooting himself in the head by catching the bullet before it made impact, and it kept Jotaro alive when he was at the verge of death by pumping his heart with its hand.
- Precision: Star Platinum is an incredibly precise stand. It is able to catch microscopic objects between its fingers and safely remove flesh buds from people's brains without any trouble.
- Enhanced Eyesight: Star Platinum has enhanced eyesight. This allows it to see up to four kilometers of landscape, as well as identify small details in images that a regular person would not be able to make out.
- Star Finger: Star Platinum can extend its middle and index fingers to a length of two meters or less. This allows it to stab its opponents from afar if it cannot reach them with its usual punches. It can also be used as a surprise attack.
- Time Stop: This is an ability that Star Platinum gained after Jotaro's fight with DIO. It allows Star Platinum to stop time for five seconds, allowing Jotaro to turn the tables in battle.
