So, as we all know, One Piece is famous for having some of the best plot twists in manga. I'm not saying that other series don't have them, just that OP consistently provides good ones. With that in mind, I'd like to find out what everyone's favourite plot twist is. There's quite a few to choose from.
If your favourite twist isn't one of these, please leave a comment explaining it, or discussing your choice. No flaming please.
