Tips for beating Brock Edit

  • Brock RBY

    Brock's R/B Sprite

    Both Geodude and Onix have double weaknesses to Grass and Water. If you have a Grass or Water-type Pokémon, using its STAB moves is probably the quickest way to win the battle.
  • It is also possible to target Geodude's and Onix's weaker Special stats. Even Pokémon that are weak to Rock-types that carry strong special-based moves can succeed in this gym, especially since Brock's Pokémon don't have STAB moves.
  • (YELLOW ONLY)- Pokémon with Fighting moves are also available to help take down Brock.

Good Pokémon to Use Edit

  • Squirtle - Can destroy both Geodude and Onix with STAB Water-type attacks.
  • Bulbasaur - Can destroy both Geodude and Onix with STAB super-effective Vine Whip.
  • Mankey (Yellow only) - Can destroy both Geodude and Onix with STAB super-effective Low Kick.
  • Nidoran♂ (Yellow only) - Can beat Geodude and possibly Onix with super-effective Double Kick; however, it learns Double Kick very late in Red and Blue, and only learns it early in Yellow.
  • Nidoran♀ (Yellow only) - Can beat Geodude and possibly Onix with super-effective Double Kick; however, it learns Double Kick very late in Red and Blue, and only learns it early in Yellow.
  • Butterfree - Butterfree has a decent Special stat off of which it can launch neutral Confusions, which will deal good amounts of damage to both Geodude and Onix, as both have low Special stats.
