Re: If the Shichibukai are so strong, then why havent they found One Piece?
not neccesarily. there are more pirates than just the yonkou. this is the age of pirates, remember? so there are probably lots of pirate crews, strong and weak alike. so the marines, who tried to defend the whole world against this threat, need lots of subordinates to watch over all those big area - the world aint so small.
But probably the Yonkou ARE stronger than the shichibukai - shanks and WB are being 50% of them, and dam, they're strong!!
But don't underestimate the shichibukai too, if they got someone like mihawk, they are really strong too!
