Steven Stone (Japanese: ツワブキ・ダイゴ Daigo Tsuwabuki) is a skilled Trainer who specializes in Steel-type Pokémon. He is the Champion of the Hoenn region's Pokémon League in Pokémon Ruby, Sapphire, Omega Ruby, and Alpha Sapphire, as well as the canonical Hoenn League Champion in Pokémon HeartGold and SoulSilver. A collector of rare stones, Steven is the son of the president of the Devon Corporation, and makes his home in Mossdeep City. In the Hoenn-based games, he wanders the region, aiding the player on their journey. In Pokémon Emerald, he is no longer the Champion, with Wallace taking his place.
