This cube craft is the Doma, based on the manga series “One Piece”, this paper toy was designed by blackignus. "Bohemian Knight" Doma is an infamous New World pirate who allied himself with Whitebeard.
Doma is a man with black curly hair and a beard that seems to have lines that extend to his eyes. He wears a red large headband and a necklace with big light blue square jewels on it. His neck appears to have a scar on the lower right, and he sports a large and long light brown coat with a wide dark red collar and cuffs, closed by a belt. He also wears loose blue pants tucked inside simple boots.
A monkey is seen perched on his shoulder. The monkey is usually seen wrapping its prehensile tail around Doma's arm; it also carries a flintlock pistol that it fires on Doma's behalf during battle.
Doma has managed to make himself an infamous reputation in the New World, and to ally himself with Whitebeard.
Doma is a swordsman who employs a dual-sword style and is seen fighting with both swords held in a reverse grip. His exact level of swordsmanship remains unknown, however it is presumed quite high. In the anime, he was capable of fighting on par with Vice Admiral Momonga to stall him. He is also very agile and seems to prefer kicking-style attacks.
The monkey perched on his shoulders appears to be able to wield a gun well, and serves as Doma's "third hand" for shooting the gun in battle, since Doma is already carrying two swords with him.
