One Piece: Dead End Adventure

One Piece: Dead End Adventure (2003) is the fourth theatrical film from Toei Animation's One Piece franchise — an action-packed anime adventure you can watch online on iFILM. Directed by Konosuke Uda, it drops the Straw Hat Pirates into a secret underground race among pirate crews, with a 300-million-berry prize drawing every dangerous crew in the sea.

The race's shadow ruler is Gasparde, a former Marine general who switched sides and now runs the competition on his own brutal terms. Mayumi Tanaka reprises Luffy with the same unstoppable energy fans know from the series. The story sits outside the main manga arc, so it works as a standalone, but the real draw is scale: the ship battles and final confrontation run larger than anything a TV episode budget could support.
