Jotaro's mother, Holly, also becomes affected by this and develops a Stand that drains her of her life due to her spirit not being powerful enough.

His grandfather, Joseph Joestar and his assistant, Muhammad Avdol pay him a visit and explain to him that his evil spirit is actually an emanation of his spiritual power, called a Stand and that its sudden appearance is related to the awakening of Joestar's sworn enemy, the vampire DIO. One day Jotaro claims to be possessed by an evil spirit and locks himself at a prison.

He is the first character introduced with a Stand, Star Platinum. Jotaro Kujo (空条 承太郎 Kūjō Jōtarō) is the protagonist of Stardust Crusaders and the main character in Jojo's Bizarre Adventure: Heritage For The Future.
