Diavolo appears as the enemy faced in Chapters 12 and 13 (as "The Boss"; A suited silhouetted individual shrouded in shadow), as well as in 20 and 22, where he utilizes King Crimson to, within the game's perspective, alter time. Diavolo boasts the most health out of all enemies fought. The game, due to a completely different interpretation, does not refer to King Crimson's ability once as "time erasure". In Chapter 12, Bucciarati must survive for one minute, and in Chapter 13, he must deplete a very small portion of The Boss' health to succeed; In Chapter 20, Polnareff must also deplete a small portion (equivalent to a fifth) of Diavolo's health, and in Chapter 22, Giorno and Gold Experience Requiem must finally defeat Diavolo.
