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.
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.
