Leo

Leo is a dwarf from Tontatta Kingdom who is the "Tonta Corps leader" (Tonta-heichō?) of the Tontatta Kingdom. He is the 5th division commander of the Straw Hat Grand Fleet. Leo, like all the other dwarves, is small and has a large fluffy tail and a pointy nose. He has long brown hair and wears a green hat similar to a crown that has one of its points bent. He also wears a jumper, goggles, boots, gloves, and a tie. He usually carries a gun with him. Leo has a warrior-like personality, which befits his role as the leader of his kingdom's military corps.

He follows the laws of his kingdom closely, as he demanded Robin give a weapon or her clothes in exchange for her freedom. He is also trusted by the other dwarves in the kingdom to lead them into battles, and to issue commands and instructions when needed. Like his fellow dwarves, Leo is extremely gullible. However, he appears to possess an additional, humorous measure of obliviousness, as he misinterprets Princess Mansherry's flirtatious behavior towards him as selfishness, meanness, and capriciousness, not realizing that it is actually caused by her feelings of affection towards him. Despite his gullibility, Leo refused to believe Trebol when he said that Usopp lied to them about being a hero. He, like Kin'emon, appears to be unaware of the existence of Devil Fruits, as he referred to his and Robin's powers as magic.
