Leonardo

Leonardo or more commonly referred to as Leo, is a fourteen one-year-old BLANK who becomes the shipwright, of the Thunder Beast Pirates, and is the consumer of the Seruro Seruro no Mi. Due to his "criminal" actions alongside his crew, he managed to gain a bounty of 24,000,000.

Personality and Relationships
Leo is a young man who was born with aspergers, because of this he shows numerous of the signs. Leo is extremely shy, though this also partially due to his past. He is a picky eater, his diet consisting of a minimal amount of things, though despite this, he is extremely smart and gifted in the area of architecture, designing, and over all art as a whole, making him an amazing Shipwright. His brain power is able to keep up with the likes of even Kurenai and Newton.

Physical Capabilities
Leo is the weakest in terms of physical strength, but in return he is a master when it comes to strategies and planning who is able to take over the entire battle field in an instant given his talent. Despite this lack of physical strength, he is able to carry his spear with little to no problem and fight with it, if need be. Leo in turn has extremely high stamina and endurance, despite his lack of strength, this allowing him to outfight numerous foes when it calls for it.

Devil Fruit
Leo ate the Seruro Seruro no Mi allowing him to perfectly manipulate, multiply, and produce cellulose. This giving him a range of attack and defense capabilities. Leo utilizes this fruit in conjunction with his weapon, the weapon itself being made out of wood then modified, he can manipulate it freely without having to get close to foes, this making up for his weak physical strength. This also allows him to "levitate" and fly via manipulating his clothing.
