geodude and onix
Ground type Pokemon like Sanshrew and Onix (Onix is half rock, half ground, like a Geodude)
all the Pokemon on route 210 in Pokemon diamond and pearl are ponyta, geodude and if your really lucky you can find onix.
Onix only evolves when you trade it while it is holding a metal coat. I would advise catching a geodude for the beginning of the game but try to catch a rhydon and evolve it to a rhyhorn, that is the best rock type before you beat the elite 4
Brock isn't in Diamond and Pearl. He is in another game but i forgot which one it was. Hes in Pokemon LeafGreen and FireRed as the frist gym leader and there he got geodude and onix
onix is more stronger than geodude because when it become steelix it will be lot stronger gloem and steelix are well evened fight......... at first geodude is better than onix (stats)
