The stylish and intimidating boss fights in Persona 5 Royal are some of the most memorable parts of the game, for better or for worse. Players who've made their way through the game will understand the difficulty posed by the Shadow Okumura boss, contributing to one of the most controversial parts of the game. While this boss likely won't appear in Persona 6, the next entry in the series might draw from Persona 5 Royal and include its own boss designed around the signature mechanic required to beat Shadow Okumura.
