Marianne

Miss Goldenweek (Ms April Fools Day in the English 4kids dub) is an officer agent of Baroque Works, her partner is Mr. 3.

Personality
Her personality is that of one laid back to the point of fault. She, for instance, is perfectly fine with having a picnic during an ongoing battle. Another example of this was when she sat a few feet away from a cup of tea, apparently too lazy to walk over to it and picking it up by herself. Obviously, Mr. 3 understood this, and yelled at her before giving her the cup.

Abilities and Powers
Goldenweek's power derives from influential powers of color, called "Colors Trap". Rather than any Devil Fruit, she paints a little symbol on people or inanimate objects in order to influence their behavior with it. As demonstrated on Luffy, his simple mind was easily influenced by her colors trap.

Due to her painting skills, many readers and fans alike believe that Miss Goldenweek may have eaten a Devil Fruit of some sort. Oda however explained in the SBS that she was merely a type of a hypnotist that uses colors as a manner of suggestion.

History
After the initial uncovering and subsequent flight of Princess Vivi from the organization, Crocodile sends Goldenweek and Mr. 3 to lie in wait for Vivi and her Straw Hat escorts on the island of Little Garden. Goldenweek barely participates in the battles that follow, but when she does she is more than a match for the simple-minded Luffy, who has to be rescued by Usopp. Unless she is controlling an opponent with her paint, she is nearly defenseless, as shown when Carue defeats her easily offscreen.

Miss Goldenweek has starred in her own mini-arc on the chapter covers of the manga during the Water 7 arc. Whereupon finding out that Baroque Works has been exposed after the Arabasta arc; she, along with Mr. 5 and Miss Valentine, fly from Little Garden on top of a pterodactyl with the help of a Color Trap to go visit them in jail. However, the symbol is washed away in a storm and the three are dropped onto a resort island where Hina, Jango, Ironfist Fullbody and their Marine unit happen to be vacationing. She manages to break out the other agents (except for Crocodile and Mr. 1) and starts a new Spiders Cafe with the ones that escaped.

Translation and Dub Issues
Her name, "Goldenweek", comes from a series of national holidays in Japan known as Golden Week, similar to Spring Break in the United States.

Mr. 3 and Miss Goldenweek's involvement in the Little Garden was removed in the 4Kids dub. Though she still is mentioned during Vivi's Baroque Works debriefing, and is still featured in the localized Grand Battle video game. During Vivi's Baroque Works debriefing, Nami commented Miss Goldenweek saying "Isn't she's too young to be a creep" even though Nami had never seen Miss Goldenweek before.
