Amazon

Amazon (アマゾン Amazon) is the elderly gatekeeper of Skypiea and informer at the entrance to Skypiea known as Heaven's Gate.She lets people in even if they can't pay her exorbitant toll, but purposely fails to tell those who don't pay about the consequences for entering the city.

Personality
Mostly she seems to care about nothing. She explains to the Straw Hats that she is not a warrior and if they refused to pay the toll she would not try to stop them from entering. Her calm demeanor remained even when she found herself flooded with people fleeing to the Blue Sea in a panic. While she did not refuse to answer the Straw Hats questions, she neglected to them vital information about Skypiea's currency, Extol, or the consequences of not paying the toll to enter.

History
When the Straw Hats arrived in the sky, they found their way to Heaven's Gate. Amazon appeared before them to take photos of each of them. The Straw Hats first mistook her for an angel, commenting on how wrinkly she is at the same time. Amazon explained the rules for entering Skypiea and asked for an immigration fee of 1,000,000,000 per person, after the Straw Hats told her that they cannot afford it she informed them that they can pass if they wanted to, however, she did not tell them that they would become outlaws for doing so. (1,000,000,000 is equal to 100,000).

She is later seen when the residents of Angel Island tried to flee to the Blue Seas. She was panicking because she had never had that many people come through the gate at once.

She is seen once more in during the celebration following Enel's defeat, dancing with Nami.
