Nelson Royale's ship

Commodore Nelson Royale's main ship is only seen in the Warship Island filler arc. This vessel is unlike any other previously seen navy ship. It is a large ship with plenty of gilding and an odd-shaped hull. It is also more wide than a common marine ship and its rudder had a structure attached to it strangely akin to that of a house. It compromises of three frontal structures, the middle one being the highest, having an odd, seven pointed red roof shape. The middle structure is where Nelson usually resides. There are also structures in the back of the ship. The ship's clothes has the number "8" on it.

For offense, the ship, unlike standard marine ships, has no inbuilt "slots" for cannons, but instead has portable cannons to be moved around on deck. It also leads a fleet of other marine ships, and while those circle around the targets with chains linked to each other, effectively sealing off the escape paths for the trapped vessels (known as the "Akuyoku" formation), the main ship launches attacks. The ship's main weapon is the "Big Elimination Cannon", which is normally pulled in. This was destroyed when Usopp managed to fire a cannon shot into it, just as it was being prepared to shoot, resulting in its explosion.

In the end, with the assistance of a Sennenryu, Luffy delivered a devastating kick that split the ship in two, effectively destroying it completely.
