You find Champion Steven at Ruins of Alph.
Steven, as the Champion of Hoenn Region, gives you one of the Hoenn starters, which are Treeko, Mudkip, and Torchic.
He is the Hoenn Champion. But he isn't in Soul Silver for a battle. He'll tell you that Latios is roaming Kanto. He let's you have one of the Hoenn Starter Pokemon. He also let's you trade with him.
Steven
You cannot go to the Hoenn region in Pokemon Heart Gold and Soul Silver. Just because you get a Hoenn starter from Steven Stone (Hoenn League Champion) doesn't mean you go to the Hoenn region.
The Champion of the Hoenn region in Pokemon Ruby and Sapphire is Steven Stone.
Steven / Wallace aren't there.
In order to get Hoenn Starters, you have to have defeated Red at Mt. Silver. Then, go to Silph Co. in Saffron City. Once there, talk to Steven, the Hoenn Champion. Choose one of the colored stones to match up to the type of the Hoenn Starter pokemon.
No, you only go to Kanto and Johto. It would be epic if a game went through all five regions. However, you can catch Hoenn pokemon, legendaries and you meet Steven, the Hoenn League Champion several times in the game.
You don't find Steven in Mount Silver. You find Steven in Silph Co. after beating Red. He will give you a Hoenn starter.
i saw it was possable to battle steven in heart gold his in the ruins of alpha but i went there but he is not there and i have got the starter of him ( i picked mudkip ) and now he is asking to trade a forretress for a beldum so good luck on you quest
Steven Stone is the Champion of the Hoenn League and a Steel type Pokemon trainer. At his house in Mossdeep City, he will leave a Beldum for the player to adopt.
Turtwig is a Hoenn region starter Pokemon. Thus, it cannot be found in the wild for capture in HeartGold. However, after defeating Red at Mt. Silver, you have a chance to get a Turtwig. Go to Silph Co., talk to Steven (the Hoenn champion), and choose the green stone to get a Turtwig.
