JoJo

JoJo is a term used to talk about the main protagonists of JoJo's Bizarre Adventure, which comes from two "Jo's" within each of their names.

Jonathan, Joseph, Jotaro, Josuke, and Jolyne are each referred to as "JoJo" at least once in the manga. Giorno is referred to as "GioGio" in the non-canon Purple Haze Feedback novel, and Johnny Joestar references JoJo as one of his nicknames from his fans, but he is never called this directly. Josuke Higashikata, from JoJolion, is the only JoJo not to be referred to as such.
