There have been a plethora of arcs throughout the story of One Piece, but while some may be fairly straightforward and used primarily for lore dumps and character development, some can be a little more over-the-top. Sure, One Piece may be known for getting a little exaggerated every now and then, but these specific arcs are where the narrative and action went above and beyond what anyone could have expected, making for an outlandish, but also memorable section of the adventure.
