Curly Dadan

Dadan is Monkey D. Garp's friend. Garp entrusted him to take care of Portgas D. Ace shortly after the boy's birth. Later, Garp also left his grandson Luffy in Dadan's care. As Luffy and Ace both grew up in Fuschia Village, Dadan is also a resident there. Though Dadan is shown to be angry when Ace nearly killed people who offended his heritage, Ace did seem to like him.
