Diego is a large tanned man with disproportionately narrow legs. Under his red cap, he has white hair that extends down his neck, as well as white sideburns. Diego wears a set of blue overalls, a string of blue beads around his neck, and a white tool belt around his waist. He has a brown cloak draped over his shoulders. He suffers backaches due to his age and the hard nature of his work.[1]
Personality
Diego is a stubborn craftsman, highly proud of his wax modelling skills and of his son, who inherited his ability. Throughout his whole life, he met a lot of pirates such as Shanks and Edward Newgate and began to admire them and to share their desire for freedom. He has a habit of making wax figures of the pirates he has met and admires.
Relationships
Regis
He is Diego's son. Due to Regis' will to be a Marine and abandonment of the wax modeling profession, they lost contact with each other until the events of Episode of Luffy.
Koby
Diego respects Koby very much, due to being a Marine that admires Monkey D. Luffy in spite of Luffy being a pirate.
He is a skillful wax modeler who made a lot of infamous pirates' wax statues. He also made half of an Admiral Kizaru statue and wishes to make one of Zoro. Diego also has a talent in voice impersonations, perfectly imitating Borsalino's voice.
When Whitebeard died, Bilić took the control of the island and Regis joined the Marines, against Diego's will.
Episode of Luffy
When the Thousand Sunny fell on the island, it destroyed Diego's house. Later, he met Luffy and they started to talk about pirates. Diego then decided to show Luffy his wax statues. After Luffy had a flashback, Usopp and Chopper came in and Usopp spotted the first wax figure that Regis made. Diego then decided that he would deliver the wax figure to his son but due to his age, Luffy offered to make the delivery.
While the Straw Hat Pirates were attacking Bilić's Marine base, Diego met Koby, who had an idea to put an end to Bilić's tyranny. After Luffy defeated Bilić, Koby used Diego's statue of Borsalino to claim the end of Bilić and his deportation to a court-martial. Then Diego and Regis met again, but this time the craftsman let his son decide his way. Later, Diego started to model Luffy's wax statue.
Trivia
Diego's collection is similar to a wax museum among which London's Madame Tussauds is one of the most famous.
When Luffy learns about Diego's wax modelling skills, he asks him if he knows about "that three-guy".
Luffy's expression and position on his wax statue resembles his Bounty photo.
Marco's position on his wax statue resembles the one when he got introduced in the Chapter 434.
Diego's meeting with the Red Hair Pirates is the only one apparently placeable, due to their wax statues' appearance, which is of more than 12 years ago (Shanks has his left arm and straw hat).
