The stealth mission to turn toys back to humans.

(Note: Episodes 619-628 are a filler arc "Caesar Retrieval" leading into Dressrosa. The main Dressrosa narrative technically concludes around Episode 691, with subsequent episodes acting as an extended epilogue and setup for the next saga.)

The Dressrosa Arc constitutes episodes of the One Piece anime. It is preceded by the "Caesar Retrieval Arc" (Filler) and followed by the "Silver Mine Arc" (Filler) before transitioning into the Zou Arc.

The Dressrosa Arc begins immediately after the events of Punk Hazard as the alliance lands in the "Country of Love, Passion, and Toys". 1. Arrival and The Corrida Colosseum (629–642)

Following the events of the Punk Hazard Arc, the Straw Hat Pirates, aligned with Trafalgar Law and the Heart Pirates, set sail for Dressrosa. Their objective was twofold: to destroy the SMILE Factory run by the villainous Warlord Donquixote Doflamingo and to locate the location of the Poneglyphs. However, the arc quickly expands into a massive conflict involving the World Government, the Revolutionary Army, and the rise of Luffy’s Grand Fleet. Spanning over 100 episodes, Dressrosa is a landmark arc that bridges the gap between the early New World adventures and the political upheaval of the "Four Emperors" saga.
