Moby Dick

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

Ship Design and Appearance
Like the rest 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. 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.

History
Whitebeard was aboard this when Rockstar attempted to deliver Shanks's letter. Recently Shanks has met up with Whitebeard, revealing that even his massive ship is small compared to Whitebeard's. A few wooden panels were cracked by Shanks' "spirit" when he boarded the vessel.

With Ace's execution drawing near, The Moby Dick has started to sail toward Marineford by destroying all 23 battleships sent to watch over it. On the way to Marineford the Moby Dick was coated so that it could travel underwater. It later resurfaced in the plaza at Marineford.

Trivia

 * Its name and design is based on the classic tale "Moby Dick"
