Sis & Bro (Japanese: うみきょうだいBeach Siblings), known as Sis and Bro in the Generation III games, are a pair of Pokémon Trainers that first debuted in the Generation IIIgames. They are a combination of an older sister Swimmer and a younger brother Tuber, though the unused Diamond and Pearl version has the ages of the two reversed.
The male Tuber in the Ruby, Sapphire, and Emerald version of the class uses different colors than actualTubers. This is because the Tuber Trainer class uses a different color palette than the Swimmer class.
Though the Sis and Bro class exists in FireRed and LeafGreen, there are no male Tubers in FireRed and LeafGreen.
