11- Shanks is described to be very gentle with his friends but to be ruthless with the youngbloods who think too high of themselves. He goes out of his way to break them down (which explains what he did to Eustass Kid). It is said that it’s better to not make Shanks angry because when he is angry no one can stop him.
12- Shanks does not consider the straw hat to be more precious than life. This means the love Luffy has for the straw hat might be too much.
13- Big Mom created her own empire from her own family and trusting nothing but her own blood. She’s a ruthless business woman and is considered the most dangerous pirate captain because of her deep rooted connections and ruling as more mafia boss than a pirate!
14- Yonko do not fight each other because if two fight neither will survive and more importantly they believe it might expand the influence of the other two Yonko.
15- The World Government constantly tries to take back territories slowly from the Yonko but it’s a back and forth thing. Every Yonko has special island just for food supply and unfortunately the place where Ace and Jinbe fought was Whitebeard’s special food supply island.
