From Bulbapedia, the community-driven Pokémon encyclopedia.
Brock's Geodude (Japanese: タケシのイシツブテ Takeshi's Ishitsubute) was the second Pokémon acquired by Brock. He caught it sometime after Flint gave him his Onix and before Ash arrived at Pewter City to challenge him. Its Japanese voice actor is 三木眞一郎 Shin'ichirō Miki and its English voice actor is Michael Haigney.
Like all of Brock's Pokémon, Geodude received very little screentime. Brock typically used it in situations in which he needed to battle, but could not use Onix because of its enormous size. Brock entered Geodude in the P1 Grand Prix, despite it lacking Fighting-type characteristics; it lost in the first round.
According to Susie, Brock kept Geodude very healthy — he regularly polished it.
Brock ended up giving Geodude and two of his other Pokémon to his eldest sibling, Forrest, who took on the role of Gym Leader of the Pewter Gym.
