Conversation between Oda and his editor.
Editor; Oda San, we should differentiate Shanks and his crew from other Yonko during their description.
Oda; why?
Editor; well, Shanks is a fan favorite, and he gets a lot of attention from readers so I feel like we should differentiate him from others to make fans excited, fuel their interest and anticipeitione.
Oda; yeah, I guess you're right. Come up with something, something very unclear or rather confusing that wouldn't mean enithing but would make them look unique and point out from others.
Editor; Oda San, what about if we say that they are the most balanced crew?
Oda; let me think about it, ehem... yeah, it would make! We are not hyping their strength or promising the reader too much, it's something meaningless, I like it.
Editor; what if we go little bid further and say that they made names for themselves?
Oda; yeah, it's fine, I can explain it whiteout breaking the power balance between Yonko, it's explainable so you can add it there.
This conversation isn't real, I made this to show you what happens during chapter creation, discussion between Oda and his editors and how decisions are made etc.
