Cocoa


 * Not to be confused with the real archaeologist of the 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. 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.

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 was told that she is a fake.
