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.

Trivia

 * Giorno Giovanna and Josuke Higashikata are the only main protagonists who were never referred to by the nickname "JoJo" (or the stylized "GioGio") by other characters in the series.
 * The only time the stylized "GioGio" is used when referring to Giorno is during the ending of the non-canon novel Purple Haze Feedback.
 * All the JoJo's except Gappy are called JoJo at some point
 * Jonathan 's nickname is JoJo
 * Joseph 's nickname is JoJo
 * Jotaro 's nickname for the first half of SDC is JoJo
 * Josuke is called JoJo by bullies in the first episode
 * Giorno is called GioGio by Fugo in PHF
 * Jolyne is called JoJo by her mom and her lawyer

 * My theory is that Gappy is gonna find his "new" identity at the end of JJL and be like "I am JoJo"
