Jojo's Bizarre Adventure's eighth part is a mirror of its fourth, meaning there are plenty of mirror universe counterparts to classic JoJo's Bizarre Adventure characters. Being set in Part 4's Morioh means that JoJolion had the opportunity to show Diamon is Unbreakable's many characters in wildly different situations and circumstances. While some characters, like Yoshikage Kira, share the same name, others have had a few changes to their names, stands, appearances, or even all three. The result can be a fun read for long-time fans of the series as JoJolion puts a new spin on beloved characters.
