<P> Other revolutionaries are: Dragon's comrade Emporio Ivankov (エンポリオ ・ イワンコフ, Enporio Iwankofu), nicknamed "Miracle Person" (奇跡 の 人, Kiseki no Hito), who is the queen of the drag queen (お釜, okama) kingdom Kamabakka (カマバッカ), and can inject hormones into a person's body by making his finger nails into syringes, creating various effects like increased healing abilities, increased vigor, or changing the person's gender; Inazuma (イナズマ),, who can turn his hands into giant scissors capable of cutting and deforming almost anything as if it were paper; and Bartholomew Kuma . </P> <P> The Seven Warlords of the Sea (七 武海, Shichibukai), the full title being The Royal Seven Warlords of the Sea (王 下 七 武海, Ōka Shichibukai), are a group of up to seven powerful pirates sanctioned by the World Government who hand over a fraction of their loot to the Government . The Government's idea is to use powerful pirates to fight all the lesser ones . Other pirates consider the Warlords to be "government dogs". For their allegiance, the World Government pardons these pirates for their crimes and removes bounties from their heads . The Seven Warlords are loosely based on the European privateers, government endorsed pirates considered heroes in their homeland and pillagers in others . Initially, the group's members are: Dracule Mihawk, Crocodile, Gecko Moriah, Jimbei, Boa Hancock, Donquixote Doflamingo, and Bartholomew Kuma . Following the exposure of Baroque Works, Crocodile is replaced by Blackbeard, who soon leaves the group again, along with Jimbei, who resigns to side with Whitebeard against the World Government, and Moriah, who is discarded by the World Government and narrowly escapes an assassination attempt . The three open spots are eventually filled by Trafalgar Law, Buggy the Clown, and Edward Weevil . After Doflamingo's actions in Dressrosa are exposed, Law and Doflamingo are removed by the World Government . </P> <P> Skypiea (スカイピア, Sukaipia) is a land located in the sky above the Grand Line, consisting of Angel Island (エンジェル 島, Enjeru Tō), one of several solid clouds, and Upper Yard, a lost part of the Grand Line island Jaya, believed by most to have sunk into the ocean . Skypiea is inhabitited by the original inhabitants of Angel Island, including Gan Fall, Pagaya, his daughter Conis (コニス, Konisu) and their pet, the "cloud fox" Suu (スー, Sū). Also living in Skypiea are the Shandorians, the original inhabitants of Jaya, led by Wyper (ワイパー, Waipā), an extremely violent man who is initially distrustful of outsiders . With the exception of Gan Fall, most of the inhabitants of Skypiea are shown to have bird - like wings on their back . </P> <P> The Sun Pirates are a band of pirates consisting of fishmen and mermen, led by Fisher Tiger (フィッシャー ・ タイガー, Fisshā Taigā), and later by Jimbei . They attack any pirate ship they see, but no matter who is on it, they never kill directly . Their Sun insignia was created to cover up the mark of the Celestial Dragon's slave, "Hoof of the Soaring Dragon", since Tiger Fisher bore the mark from being a slave . But he had escaped the World Nobles and during his escape he freed other mermen / fishmen and Boa Hancock and her two sisters . With the Sun insignia, the World Government was unable to claim the slaves due to mass confusion over whether they were Sun Pirates or not . Other members include: Arlong, Aladdin, Macro, Choo, Kuroobi and Hatchan . The group eventually disbands when Jimbei joins the Seven Warlords of the Sea . </P>
