One Piece is currently in its final saga, and that in itself means that the story is now much more intense than ever before. The stakes are higher, and the scale of everything is just much bigger. This has been very prevalent in the very first arc of the final saga, the Egghead Island arc. Of course, with high stakes and bigger scale come stronger villains, and one simply cannot ask for more than the Five Elders in the One Piece world.
