How to Beat Brock

Use Grass and Water Type Pokemon

Brock's Pokemon has weak defense against Water-type and Grass-type Pokemon. If you have Squirtle or Bulbasaur as your Starter Pokemon, this won't be a problem. You can easily defeat Brock by using either a Water-type or Grass-type move. However, make sure you are at least three levels higher than all of his Pokemon.

Learn Metal Claw on Charmander

Brock's Pokemon are strong against Charmander because it is a Fire-type Pokemon. It would be best to train Charmander until it reaches at least level 13 to learn Metal Claw, a Steel-type move. Brock's Pokemon has weak defense against Steel-type moves, which is why Metal Claw would help defeat Brock.

But with Charmander's type disadvantage against Brock's Pokemon, it would still be better to level it until it has evolved to Charmeleon at level 16 or higher.

Best Team to Beat Brock

When Starting with Bulbasaur

Pokemon FRLG - Ivysaur Ivysaur Pokemon FRLG - Mankey Mankey

Since Bulbasaur has a natural type-advantage over Brock's team, having one at level 14 at least and learning Vine Whip should be enough to take on Brock's whole team. Reaching Level 16 to evolve it into Ivysaur will make the encounter easier.

In case you need a back-up option, we also recommend getting a Mankey from Route 22, west of Viridian City. Its Fighting-type Low Kick and Karate Chop can deal massive damage to these Rock-type foes.

When Starting with Charmander

Pokemon FRLG - Charmeleon Charmeleon Pokemon FRLG - Mankey Mankey

Trainers who chose Charmander as their starter may have the hardest time with the first gym battle. As suggested above, it would be best to let Charmander learn Metal Claw at level 13 to have a reliable move against the Rock-type team.

We also recommend evolving Charmander into Charmeleon at level 16 or higher just to pad its stats for survivability.

Alternatively, you may want to catch and train a Mankey from Route 22, west of Viridian City. This should equip you with a strong Fighting-type to deal with Brock's team. Ideally you would let Mankey reach level 11 to gain access to Karate Chop.

When Starting with Squirtle

Pokemon FRLG - Wartortle Wartortle Pokemon FRLG - Mankey Mankey

Much like Trainers with Bulbasaur, Squirtle Trainers should have a relatively easy time with the Pewter Gym. Having Squirtle at level 14 or higher and having Water Gun will make the encounter easy. Trainers may opt to evolve Squirtle into Wartortle to increase its offensive and defensive stats.

In case you need a back-up option, we also recommend getting a Mankey from Route 22, west of Viridian City. Its Fighting-type Low Kick and Karate Chop can deal massive damage to these Rock-type foes.
