Johnny Joestar

Johnny Joestar (ジョ二ー・ジョースター) is a racer in the Steel Ball Run race and serves as one of the two main protagonists of the series, along with Gyro Zeppeli. He is the alternate universe counterpart of Jonathan Joestar, the protagonist of Part 1. He is a paraplegic, and is usually seen wearing a hat with a horse shoe decoration on the front.

At the beginning of the story Johnny starts out rather as a supporting character to Gyro. At first it wasn't clear whether Steel Ball Run was meant to be a part of the Jojo series, but when it was officially announced to be one by volume 5 (incidentally also the turning point for the entire series as it switched from Weekly Shounen Jump to be released in the seinen magazine Ultra Jump), subtitled as Jojo's Bizarre Adventure Part 7, Johnny started to gain more and more the weight of a main protagonist alongside Gyro, developing a stand power and getting more focus on his individual actions.

Storyline
Johnny Joestar, also known as "Joe Kid" or "JoJo", was a racing prodigy. However, when waiting in line for a play, the girl he was with convinced him to cut to the front of the line and bribe the bouncers to throw out the youth in the front of the line, who had been waiting through the night. The youth shot Johnny, resulting in his being paralyzed from the waist down and sent to a hospital, where he was physically abused. Having lost all the friends and respect he had earned as a jockey, no one visited him during his stay in the hospital.

Near the beginning of the series, Johnny Joestar encountered Gyro Zeppeli and was brought to his feet upon touching Gyro's steel ball. Believing Gyro to be capable of teaching him to walk, Johnny joined the Steel Ball Race and followed him to be trained.

Personality
Johnny is still aggressive and forceful. However, after being taken off his feet by Gyro's steel ball, he also closely follows his words. Johnny is stubborn and strong-willed; he refuses to accept Gyro's claims that he stood up from his wheelchair as a reflex, and races despite his disability making even mounting a horse difficult.

When the need arises he can be driven by dark, scrupleless determination much rather than Gyro.
