Sea King

Sea Kings are mythical sea creatures in the anime and manga One Piece, which are generally much larger than normal sea creatures. They are found in great numbers along the Calm Belt around the Grand Line, although in rare occasions they can be found in other places throughout the world.

Sea Kings make trade and travel difficult for anyone trying to cross the water where they are found. Cases have arisen where some islands in the Grand Line close to the edge of the Calm belt have ended up getting almost completely cut off from the rest of the world. In Water 7 and its surrounding islands, this led to the eventual creatation of the Sea Train as a means to travel safely to and from each of its surrounding islands.

Sea Kings are serpent-like in appearance however they vary form one Sea King to another in exact appearance along with their size. Only the strongest of ships or captains can take on a Sea King. Most other creatures in the ocean fear the sea King with the noteable acception of Bananawani. Confrontation with one by all but a few humans is unadvisable. Many characters such as Franky see the act of killing one a sign of strength and achievement.

Very few Sea Kings end up with names, only those who commonly inhabbited the same waters recieve names. The Sea King that ate Shanks' arm is known as The Lord of the Coast and Long Land Long Ring Island had a Sea King called Master of the Waters.
