Jean Pierre Polnareff holds the key to defeating the boss. The one who appeared before him wasn’t Bucciarati or his squad, but the leader of Passione, Diavolo himself. Diavolo tries to eliminate Polnareff once and for all and summons Emperor Crimson, but then Polnareff summons Silver Chariot and it is pierced with the arrow. That’s when something happens to everyone in or nearby the Colosseum. They find themselves losing strength and all fall asleep. After waking from their deep sleep, they all realize something has changed.
If you're thinking that the boss 
and Bucciarati got swapped,
إن كنت ترى أنَّ الزعيم وبوتشاراتي
،قد تبادلا
Wenn du glaubst, Bucciarati könnte
mit dem Boss vertauscht sein,
Si crees que el jefe y Bucciarati
cambiaron de cuerpo,
Si crees que el jefe y Bucciarati
cambiaron de cuerpo,
si tu crois que le parrain
a pris la place de Buccellati,
Se quello che pensi è che Bucciarati
si sia scambiato col Boss,
Se você acha que o chefe
e o Bucciarati, trocaram de corpo,
Если ты подозреваешь, 
что в него вселился босс…
