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.
The reason I was able to swap souls 
with this turtle and survive is
سبب تمكُّني من مُبادَلة روحي مع روح
هذه السّلحفاة والنجاة هو
Dass ich die Seele mit der Schildkröte
tauschen und so überleben konnte,
Sobreviví cambiando de lugar
mi alma con la de la tortuga
Sobreviví intercambiando
mi alma con la de la tortuga
Si j’ai réussi à survivre
en échangeant mon âme,
Se sono riuscito a sopravvivere scambiando
la mia mente con quella di questa tartaruga,
Eu só consegui trocar de alma
com a tartaruga e sobreviver
Но стрела позволила мне 
обменяться душами с черепахой
