Literally the only villain theme thats legitimately intimidating, the haunting instrumentals with the distortions is chilling. Pucci was my favorite villain from the manga and im so happy they did him justice, this theme is perfect for how truly helpless the heroes were in the end.
The leitmotiv at 1:43 strongly resembles a famous theme from "Madame Butterfly" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vcEoBOHp-7Q.html which was composed by... Puccini ;)
