Re: One Piece Mega Convo Thread
They'll probably be accepted quite differently from the norm, though on Fishman Island they don't really have the "regular criminals" bit because only pirates go through the Fishman Island route.
Smoker is chasing Luffy because, like many marines, he wants the pirate era to end. Smoker knows Luffy isn't a bad guy, and hence his honour when Zoro saved his life in Alabasta. However, Luffy, if he becomes the Pirate King, would represent a new surge in people wanting to become pirates.
Gol D. Roger invoked an enormous change in the world's climate and started an era of criminals. Marines seek to end this era, and Smoker has wisely seen that Luffy is a large threat to it's continuation.
Of course, Smoker might have other reasons, he's still a character that has plenty of room to grow in the eyes of the reader.
