Josuke Higashikata/History
History
Josuke apparently developed his Stand off-screen in the events of Part 3, when Jotaro Kujo and company traveled to Egypt to kill DIO. As a result of DIO being pierced by the Stand-creating Arrow, Josuke, possessing the Joestar Bloodline that runs in Jonathan's body, develops a Stand, but suffers a fever not unlike that of his half-sister Holly. He is then saved by a then-high school student with a pompadour, who throws his coat under his mother's car in order to allow their car to plow safely through the snow. This then inspires Josuke's admiration for the man with the pompadour.
