Moby Dick

Moby Dick is the Whitebeard Pirates' main flagship. Its name was revealed in One Piece Yellow Grand Elements.

Ship Design and Appearance
Like the other three of the four main ships of Whitebeard, the Moby Dick is a large battleship with a blue whale figurehead. It is, however, significantly larger than the other three and possesses a blue whale figurehead colored white, and bigger than the already large Red Force. Also, while the other three ships were paddle-ships, the Moby Dick did not show any paddle-wheels on its sides. The ship is coated with special resin from Sabaody Archipelago, which allows it to submerge all the way to Fishman Island at 10,000 meters below sea level.

It originally appeared in the anime with the ship and figurehead colored blue like a regular blue whale. Later in the anime however, the figurehead was changed to white in order to match the manga.

History
With Whitebeard controlling a territory within the New World, the Moby Dick sailed through the waters of the second half of the Grand Line. Two years ago, it went to intercept the Spade Pirates after their captain and Jinbei fought.

After Rockstar, a member of Shanks' crew, had an audience with Whitebeard himself aboard the great vessel, the Moby Dick sailed to meet up with the Red Force so that Whitebeard and Shanks could talk properly. Upon breaking through a Marine blockade, the two ships met up so that their captains could discuss about Teach and Ace.

After the meeting between the two captains, the Moby Dick continued its regular course. However when it was reported that then captured Ace would be executed, the Moby Dick and the rest of Whitebeard's fleet was steered towards the locale of the anticipated execution, Marineford. Living to Whitebeard's strength, the Moby Dick destroyed 23 Marine battleships simultaneously sent to hinder its progress as it drew closer.

Along with 43 other ships belonging to New World pirate crews allied with Whitebeard, the Moby Dick and the four other main ships of Whitebeard were coated and traveled to the first part of the Grand Line through Fishman Island. With this massive pirate fleet, Whitebeard's forces invaded Marineford on the day of the execution. While Whitebeard's allies resurfaced after passing through the Red Line, the Moby Dick and the three of the four other main ships continued traveling underwater until they arrived directly into the middle of the bay of Marineford. Having done so, the Moby Dick and the other ships bypassed the large battleship blockade surrounding the island. With the Moby Dick and the rest of Whitebeard's forces arriving in Marineford, the battle to save Ace began. Later in the battle, the ship is hit by a rain of meteoric magma by Admiral Akainu, leading to its destruction, much to Whitebeard's sorrow and the crew's fury, as the ship had served them for decades. As it burned and sank, Whitebeard apologized to it for being unable to save it.

Trivia
