Joseph Joestar is the son of George Joestar II and Lisa Lisa, and the protagonist of “Battle Tendency,” the second arc of JoJo’s Bizarre Adventure. As an older man, he’s also an important supporting character in the third arc, “Stardust Crusaders,” and appears in the fourth arc, “Diamond is Unbreakable,” as well.
With his father dead and his mother absent, Joseph is raised by his grandmother Erina, under the watchful eye of his grandfather’s old friend Robert E. O. Speedwagon, now a wealthy philanthropist. Joseph is a master of Hamon, which he uses in the late 1930’s to battle the Pillar Men, a group of powerful ancient beings who want to rule the world. It turns out they’re the ones who created that Stone Mask that turned Dio Brando into a vampire.
Joseph befriends an American pickpocket named Smokey and another Hamon user, Cesar Zeppeli, the grandson of Jonathan Joestar’s mentor. They both train under Lisa Lisa, the last Hamon master on Earth, who Joseph only later learns is his mother.
Joseph defeats the Pillar Men, sending Kars, the last and most powerful, into outer space, where he’ll float forever as a sentient, frozen statue. Once that’s done, Joseph Joestar thinks his Bizarre Adventure is done, but he’ll have to return to action years later to help his grandson when Dio Brando returns.
