Joestar Family

The Joestar Family (ジョースター家) is the main family featured in the JoJo's Bizarre Adventure series, of which each of the protagonists of the series is a part of. It is a powerful family with English roots; most of its members attract particular trials and tribulations when confronting their enemies. Each member of the bloodline has a star-shaped birthmark above their left shoulder blade.

Dio Brando became a 'Joestar' after taking Jonathan's body. He too has the star-shaped birthmark on his left shoulder. Just like Dio, Enrico Pucci eventually became a joestar when he fussed with The Green Baby, which had inherited Dio's DNA. And as a result of that, Weather Report too became a Joestar due to his relationship with the priest Pucci.

In the Steel Ball Run universe, Johnny Joestar marries Rina Higashikata, tying the Higashikata Family distantly to the Joestar family.

Trivia

 * Many members of the Joestar family, starting with Jonathan, had lived tragically short lives.
 * When Pucci's Made in Heaven Resets the universe, it effectively Carries over the whole Joestar Family, with it the same Family Tree and Bloodline into the new universe, and once more when Made in Heaven's ability is activated for the last time. (With exception to Jotaro Kujo and Jolyne Cujoh, who are replaced with 'exact, but different' counterparts.)
