Steven Stone (Japanese:ダイゴ Daigo) is a character in the Pokémon franchise. He is the Pokémon League Champion in Pokémon Ruby and Sapphire. But he wasn't the champion in Emerald. He also appears in Pokémon HeartGold and SoulSilver. Steven specializes in using -type Pokémon.

In Game
Steven is the son of Mr. Stone, the creator of the PokéNav. Like Cynthia in the Generation IV games, Steven is found throughout the game, giving items and tips to the player throughout the game.

Pokémon Emerald
Unlike in Pokémon Ruby/Sapphire, Steven Stone is not the Champion of the Pokémon League in the Emerald Version. He is found in the Meteor Falls after you became the Champion of the Pokémon League for the first time. You can battle with Steven there, but he is much stronger and there, you can only battle him once.

Pokemon HeartGold and SoulSilver
In Pokemon HeartGold and SoulSilver, Steven is found in the Silph co. building after you defeat Red. He asks you which stone you like, then gives you one of the Hoenn starters with the stone that you chose's corresponding color. In the same place, you can trade him a Foretress to a Beldum. You can also find him inside the Pewter Museum related to the Legendary Pokemon Latios/Latias event
