As the grandson of Jonathan Joestar, Joseph is a natural-born Ripple user and eventual Stand user, wielding the psychic photographic Stand, Hermit Purple. An exuberant troublemaker with an exceptional talent for trickery, Joseph meets the fantastic threats approaching him throughout his life with initiative and impressive ingenuity, battling vampires, the Pillar Men, and malevolent Stand users. Joseph is the second most recurring JoJo in the series after his grandson Jotaro Kujo. He is also the father of Josuke Higashikata, the protagonist of Diamond is Unbreakable. Joseph is a playful person and prefers fooling around over having any responsibility. By his admission, his most hated sentences are "hard work" and "work hard",[17] and still had to be pushed to train his Ripple talent despite facing certain death if he didn't meet and fight Wamuu again. Joseph has a fairly goofy side and spends half of his fights enjoying having outsmarted his current enemy with incredibly zany schemes, which take his opponents by surprise by how silly said plans are at first sight. A show-off, Joseph loves being the center of attention and couldn't stand that his rival Caesar had a special technique.[18] With his prestidigitation talent, Joseph's boastful nature coupled with his love of pranks makes him an unpredictable force in battle. Joseph, being the outspoken individual that he is, does have a flirtatious side to him. He regularly comments on women's voluptuousness and is less than subtle with his advancements on his future wife Suzi Q. Joseph's antagonistic behavior toward Caesar when they first met may have been out of jealousy that he could seduce girls so easily. His perverted nature is ultimately revealed when Joseph decides to sneak a peek at a bathing Lisa Lisa, completely unaware that they were related, with her being his mother, no less. When Lisa Lisa practically revealed herself as his mother, Joseph was more concerned by her actual age. He loves Caesar so much!!
