Campacino is a character from the anime One Piece. He is a member of the Accino Family, serving as the first son and eldest child of the family patriarch, Don Accino. Campacino has a twin brother named Brindo, with whom he shares an extremely strong resemblance. To tell them apart, he typically wears a blue shirt, while his brother wears a red one. As the eldest son, Campacino holds significant authority over the family's operations and often oversees their bounty hunting jobs alongside his father.

In terms of personality, Campacino is confident and appears to have great respect for his father and the family business. He shares a deep bond with his twin brother, and the two work together seamlessly in battle, seemingly powered by what they call brotherly love. He has a distinct laugh that sounds like "Huh ha ha ha."

Campacino is physically powerful and possesses impressive acrobatic skills, allowing him to move with agility and speed despite his large, muscular frame. He is capable of evading attacks from Monkey D. Luffy and leaping high into the air. His most notable ability is a unique skill he performs with his twin brother Brindo, called Combination Play. This technique is not the result of a Devil Fruit power, but rather a natural ability the twins share. It allows them to become magnetic toward each other, with Campacino glowing blue and being drawn to Brindo, or being repelled away when he changes to a red glow. This power is used for swift travel across distances and as a tactical advantage in combat.

Campacino appears during the Ice Hunter Arc. He is first seen with his family celebrating, and later becomes involved in a conflict with the Straw Hat Pirates after they steal the family's prized pirate flag collection. When his brother Brindo is taken hostage by the Phoenix Pirates, Campacino angrily uses his Combination Play to travel to his location and join the fight. He and Brindo work together to attack Luffy and Tony Tony Chopper, attempting to throw Luffy into the ocean. The twins continue to fight Luffy on the ice, though the slippery surface proves to be a disadvantage. Campacino later defends Lovely Land, the Accino Family's base, when Luffy storms it to reclaim his flag. He battles against the pirate Puzzle but is ultimately defeated and forced to reveal the location of Don Accino's flag room. After the main conflict, Campacino and the remaining Accino Family members attempt to ambush the Straw Hat Pirates as they depart, but the Phoenix Pirates intervene and hold them off.

Campacino is also known to have other siblings, including Lil, Arbell, and Hockera, as well as a brother-in-law named Salchow.
