Yuri is a slim young man with black eyes and black hair. He wears a low-cut green tank top, dark colored pants with a brown sash around his waist, a white scarf and a black-gray cap.
He can be brash and doesn't seem to appreciate his father laughing at matters that aren't dire. He does care for his family as he went to find Theo.
One Piece: World Seeker
He is talking with Jeanne and his father when Luffy runs up to them. While his father is laughing at Jeanne becoming friends with a pirate, Yuri gets angered and says that at the moment it's a family matter that is most important, and runs off. At the beach, Raymon stands between his sons and a few robots, hoping to defend his family. After Luffy defeats the robots, he heads back to Raymon's home and Yuri asks why they chose to fight the Marines, with Luffy laughing and tells him to ask his father that question instead.
