One Piece (1999): Season 15

The Punk Hazard Arc is the twenty-sixth story arc in the series and the first in the Dressrosa Saga of the One Piece series, continuing on from the Fishman Island Arc and the Fishman Island Saga.

Upon finally entering the New World, the Straw Hat Pirates immediately receive a distress call from a group of people on an island called Punk Hazard, stating that they are being attacked by a samurai. Without hesitation, Luffy sets out to the blazing island, with Vice Admiral Smoker hot on his tail. On the supposedly death-ridden and empty island, the Straw Hats soon learn that they are not alone, meeting many new and old foes as they explore the purpose of the island. Punk Hazard is made up of a frozen side and a burning side. The island also contains the abandoned research laboratories of Dr. Vegapunk.

Punk Hazard is the first island the Straw Hats encounter in the New World.
