Cocoa


 * Not to be confused with the archaeologist of the real Straw Hat Pirates, Nico Robin.

Cocoa is one of the Impostor Straw Hat Pirates, masquerading as Robin.

Appearance
Unlike the real Robin, Cocoa is a very short and plain woman. She has a similar hairstyle to Robin's. Her nose is flat, similar to Robin's, but wider between the eyes, and longer. Cocoa wears a plain black dress and carries a purse. Fake Luffy has asserted her to be the closest in appearance to her duplicate out of the crew; in spite of this, Cocoa has virtually no resemblance to Robin.

Personality
Compared to the real Robin, Cocoa is not very bright. She apparently did not take into account the dangers of impersonating someone who has many enemies.

History
Cocoa is first seen on Sabaody Archipelago with Fake Zoro, Fake Sanji, and Fake Chopper. When they spot the real Chopper, she kicks away the Fake Chopper and offers him a cucumber, while the angry Fake Chopper bites her head. Suddenly, men in black suits, mistaking her for the real Robin, throw her in a bag along with Fake Chopper and kidnap them.

Fake Zoro and Sanji report this to Fake Luffy, who uses her real name, Cocoa, only to quickly correct himself, just dismisses her loss as bad luck. This drives away the real Chopper, who had advocated her rescue. Cocoa's capture indirectly helps the real Robin elude her pursuers. Chopper was on his way to rescue her, but abandons the quest when he ran into the real Usopp and Nami and learns that the kidnapped "Robin" is a fake.

It is currently unknown what the men in black suits have done with her at this time, or if they have even realized she is a fake.
