Hero of Gorons
- Oct 9, 2011
He wasn't in generation 4 or 5 either, but they still kept him in the show. The only two game generations Brock was in were 1 and 2. The series and the game are two entirely different entities and the only connection between them are the pokemon and the gyms. Also... it's Ketchum
Actually, since HG/SS are remakes of Gold and Silver, Brock is acessible.
Just take the boat to Kanto after beating the game and find the rock gym.
