Johnny Joestar (ジョニィ・ジョースター Joni Jōsutā?) is the main protagonist of Part VII: Steel Ball Run. A paraplegic ex-jockey drawn by Gyro Zeppeli's mystical abilities, Johnny joins The SBR race to find out more about the mysterious steel balls and Gyro's abilities. In the beginning, Johnny starts out as a supporting character to Gyro. When SBR was announced as Part VII in Volume 5 (a turning point for the whole series, switching from Weekly Shonen Jump to seinen magazine Ultra Jump) Johnny comes to stand as the main protagonist alongside Gyro.
