A 45 year old rubber man who talks like Sean Connery, who happens to be the "hero" of the story.
Abusive Parents: He claims that his parents hated him because they gave him the name "Monkey". However, he also claims that they were a test tube and his mother was a rubber band, and he's very badat recollecting his past, so anything he says should be taken with a grain of salt.
Artificial Human: May be this, if his claims that his father was a test tube and his mother was a rubber band are true.
Only Sane Man: Crazy as she is, she does have a couple moments (though as pointed out above, one of them is subverted).
Out of Character: In the original One Piece, Nami originally hated pirates (it took a while for her to warm up to Luffy and join his crew) and often served as the Only Sane Man to the other characters' wacky antics. Here, she joins Luffy's crew instantly without any animosity (she even marries Luffy for no explained reason) and turns out to be just as much a Cloud Cuckoolander as the others.
Sanity Ball: Picks it up whenever one of the crew needs to be sane for a moment. Whether this will stick now that Usopp has joined the crew remains to be seen.
Shameless Fanservice Girl: One of the first things she asks Luffy is if he can see down her shirt. When he answers no, she leans forward a bit and asks "How 'bout now?"
The Voiceless: She appears in the first episode, but doesn't say a word until she appears in Episode 3.
Yandere: If this bit of dialogue at the beginning of Episode 4 is any indication.
Nami:Oh, pay him no mind, *whispering* unless you want to die.
Abusive Parents: His dad essentially treats him somewhat worse than he did in the original show. He flat out tells Helmeppo that he deserved to get hit for wearing a purple suit, and later on, Morgan hits him again for no explained reason.
Spontaneous Choreography: After eating a riceball meant for Zoro, he starts "dancing"note Which is really just him stomping on one of the girl's riceballs... which itself is exactly what he was doing in the original show. to Born This Way by Lady Gaga.
Captain "Axe-Hand" Morgan
A corrupt marine captain who has an axe for a hand.
Only Sane Man: Surprisingly, despite his own ludicrous behavior, even he gets fed up with the Straw Hat Pirates' antics.
Punctuated! For! Emphasis!: Done with unusual pauses in his words, as part of his being an expy of Christopher Walken. Kuro thinks it's a tumor.
Zany Scheme: Has a plan to steal Miss Kaya's property that involves rounding up 50 goats and unleashing them onto her property in order to ruin her lawn. How this allows them to steal her property is never explained. Makes even less sense when it is revealed that property in this context refers to the goat butler's ballsack.
