At his gym. Sometimes at Diglett cave after you've beaten him.
Pewter City, in Kanto.
After beating Brock, if you haven't faced the other Gym leaders yet, go challenge them.
Brock Gives it to ya when you defeat him :D Hope it helped. I Pwn Brock :D
After you've beaten Brock go beat the other six leaders then you can fight Blue
No. He's waiting at his gym, like he should, I think.
Pewter City Gym. Same as always.
Brock is a rock type. I would suggest you use water types. His Pokemon are levels 40-50.
brock is the 6th gymleader
He has an Omastar, Kabutops, Golem (or Graveler, maybe both), Onix, and in the rematches, he has the above and the following: Rampardos and Relicanth
Brock uses rock Pokemon. The best choice would be to bring a water or fighting Pokemon to defeat him easily. A fighting Pokemon will be super-effective against all of his Pokemon. With a water Pokemon, Omastar and Kabutops may be a little trouble (both are part water).
Go through diglett cave by vermillion city, and if you have problems with the snorlax, message me.
sorry you have to trade it to Pokemon soul silver
