For the underground criminal syndicate, see Underworld.

The Underworld of the Sea (海の「暗黒街」 Umi no Ankokugai?) is a deep sea area where light does not penetrate, where normal creatures are not allowed to exist. The creatures here have either had to acquire better eyesight, or, in some cases, bio-luminescence.[1]

Creatures Encountered at This Depth[edit | edit source]

History[edit | edit source]

The Straw Hat Pirates were carried by the sea currents to this place when Luffy knocked out the kraken that was blocking the way.[1]

Franky stated that this area is approximately 7,000 meters below the surface.[1]

Trivia[edit | edit source]

  • All of the creatures that have been seen here so far are giant versions of real life animals that can be found in the deep sea.
