ONE PIECE GOLDMyth: Kuma separated the Straw Hat Pirates so they can become stronger.
Fact: The full reason behind Kuma separating the Straw Hat Pirates is still unknown though a great deal of evidence seems to point to this myth being proven at least partially true.
By Chapter 591, it was revealed that Kuma wished to save the Straw Hats. Sentomaru also stated that the user of the Nikyu Nikyu no Mi can control where to send people, which was also proven by the fact that Perona was sent to a dark castle like she wanted. The Straw Hats then landed on suspiciously convenient spots (like Zoro ending up on Mihawk’s island and Nami on an island dedicated to studying the weather). This evidence strongly supports the myth’s veracity. Even so, until it is confirmed, this cannot be taken as a fact.
