Luffy really has no intention of building a network of allies around the world.
1. Luffy has a close connection with pirates
Luffy’s network in One Piece includes many good pirates.
Not only does he have pirates as friends, Luffy has at least once worked with some pirates who were rivals such as Crocodile and Buggy.
2. Luffy has a strong connection to the kingdom
It’s not too surprising for pirates to be friends, but it’s `unusual` for pirates to be good friends with some royal figures.
3. Luffy has connections in the Navy
Luffy’s connection to the Navy isn’t even that of an enemy.
4. Luffy with the Revolutionary Army
One of Luffy’s two adopted brothers, Sabo, is the Deputy Commander of the Revolutionary Army.
5. Luffy and the Four Emperors
Almost all Yonko are enemies of Luffy, except for red-haired Shanks and his crew.
6. Many cities have good memories of Luffy
Although these territories are not led by the king, Cocoyasi village (Nami village), Water Seven and many other cities that Luffy helps on his journey all have good connections with the Straw Hat crew.
7. Before being disbanded, almost all of the Shichibukai helped Luffy
Now, the Shichibukai system has been abolished by the World Government.
Above is the giant network linked to Luffy in One Piece.
