Migas Archipelago (ミガー諸島 Migā Shotō?) is an archipelago on the Grand Line. It is known for possessing some of the most dangerous creatures of all of the oceans. It is also a swamp biome. It is located in the second half of the Grand Line, the "New World" (新世界 Shinsekai?). However, for as many dangers as the island may hold, it possesses several natural treasures, such as medicinal herbs that act as antibiotics, painkillers and anti-inflammatories.
