History

Nami's Waver being found by Luffy.

Nami's waver was first seen in the Jaya arc, where the Straw Hats discovered it on the fallen ruins of the St. Bliss.[1][2] It was old, but they decided to keep it.

When they reached Skypiea, Nami showed it to Pagaya, who repaired it, and made it good as new. Pagaya pointed out that this waver, unlike other wavers, used a Jet Dial instead of a Breath Dial, so it is able to go much faster.

It was later seen in the beginning of the Davy Back Fight arc when Nami tried it on the Blue Sea and found that it worked on it. Nami had it on the ship and after that it disappeared until it was recently shown to be in the Thousand Sunny.

When Franky explains the Thousand Sunny's Soldier Dock system at the beginning of the Thriller Bark arc, the waver is shown in its new form. It now has a figurehead resembling a Yagara Bull, and has been named the Shiro Mokuba I ("White Rocking Horse I").[3] However, Nami severely scolded Franky for remodeling her waver without her permission.
