Ruluka Island Arc

The Rainbow Mist Arc is a part of the filler arcs in the anime One Piece. This was the last arc to be dubbed by 4Kids.

Like some other fillers, this arc starts off with the Going Merry being chased by a small fleet of Marine ships led by Major Rapanui and Isoka. Luffy and crew barely escape when the Marine's Major accidentally sinks one of his own ships. The crew then make their way towards an island named Ruluka that is ruled by a dictator, who is actually an old pirate, that is over-taxing the people in order to build the Rainbow Tower. The island also has a scientist named Henzo who is researching something called the 'Rainbow Mist'. It is revealed that he is sponsored by the scrupulous Whetton, mayor of the city and former pirate. Eventually the Going Merry, with all but Sanji, Nami, and Chopper aboard, gets caught in the Rainbow Mist and discovers some children within. Eventually they all get out and it is shown that the children are actually the Marines from before.

This story arc is very interesting, because from the time that Nico Robin joined the crew, she has been seen reading books almost non-stop. These books have all been titled 'Rainbow Mist', I through VIII, and are all about the story contained within this arc. Robin states that she got the books while in Arabasta.

This arc consists of episodes 139-143 and 100-104 in the English TV version.

4Kids version
This was the last arc of One Piece dubbed by 4kids, and also the first separate filler arc (as both the Warship island arc as well as 3 of the 4 post-Arabasta fillers were removed). Regardless of the matter that the fillers are considered much more "harmless" towards children, as the children watching the anime on television are their prime targets, editing is still present.


 * In the first episode, the opening clips, where the Straw Hats are chased by Rapanui, have been almost completely removed.


 * Soldiers guns were, as traditionally, recolored (to blue).


 * Numerals have been edited out from the "Rainbow Mist" books.


 * Phillip's name was changed to "Flip".


 * Ape's Concert was renamed to "Wrecker's Reef".


 * Reik was given a distinctly Australian accent.
