Yonko (Yumoz)

The Yonko are known as the four strongest within the entirety of the world. Each member of the Yonko act as of their own separate crews. All of the members of the Yonko have dwelled within Underworld matters at some point, whether they act as brokers or buyers. None of the members are allied, nor are they enemies of each other. However, there have been occasions of conflicts between the Yonko, or allying themselves with each other temporarily. Despite having ties within the four seas and the Paradise portion of the Grand Line, their bases of operations primarily reside within the.

The Yonko are major antagonists within Green Ocean, where their crews have come across the Blooming Pirates on several occasions, which end up causing conflicts for both crews. One Yonko is the direct cause for the Blooming Pirates' formation, disbandment and reformation. Another Yonko's crew has caused many difficulties for a handful of the Blooming Pirates' crew members.
