Joseph is a playful man and prefers fooling around over having any responsibility. By his own admission, his most hated sentences are "hard work" and "work hard", and still had to be pushed to train his Ripple talent in spite of facing certain death if he didn't meet and fought 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 his plans are at first sight. A show-off, Joseph likes being the center of attention and couldn't stand that his rival Caesar had a special technique. With his prestidigitation talent, Joseph mixed his boastful nature and his love of pranks into a dangerous tool in battle.
