Johnny Joestar

Johnny Joestar (ジョ二ィ・ジョースター) is a racer in the Steel Ball Run race who serves as one of the two main protagonists of Part VII: Steel Ball Run, along with Gyro Zeppeli. He is the alternate universe counterpart of Jonathan Joestar, the protagonist of Part I. He is paraplegic jockey, and is usually seen wearing a hat with a horseshoe decoration on the front.

At the beginning of the story, Johnny starts out as a supporting character to Gyro. When Steel Ball Run was officially announced as Part VII in volume 5 (incidentally also the turning point for the entire series, as it switched from Weekly Shounen Jump to the seinen magazine Ultra Jump), Johnny started to gain more weight as the main protagonist alongside Gyro, developing a stand power and getting more focus.
