How to Beat Koga

Use Psychic-Type Pokemon

Since Koga's specialty is Poison, it will be super-effective against Grass-type Pokemon, but weak against Ground-type and Psychic-type. It is highly recommended to use a strong Psychic-type Pokemon with the move Psychic.

Ground-type Pokemon are good but have a disadvantage against Koga since 3 of his Pokemon have Levitate and can't be hit with Ground-type moves like Earthquake. Lastly, have your Pokemon at least three levels higher than Koga's team.

Prepare Status Healing Items and Berries

With Poison-type moves inflicting the status condition Poison, it is best to prepare healing items and berries. Have your Pokemon hold a Pecha Berry, or use an Antidote or Full Heal during a turn to deal with the Poison.

Best Team to Beat Koga

When Starting with Bulbasaur

Pokemon FRLG - Venusaur Venusaur Pokemon FRLG - Kadabra Kadabra Pokemon FRLG - Hypno Hypno

Players who started with Bulbasaur will have their Venusaur immune to being poisoned by Koga's team due to its typing. Since Venusaur can comfortably take on Poison-type moves, using Sleep Powder can be beneficial to gain free turns.

For a Psychic-type Pokemon, a Kadabra with Psychic at Lvl. 36 might be your best bet with its high Speed and Sp. Atk stats. The nearest Abra you can catch is on Route 24 or 25. A Drowzee in Route 11 is nearer to Fuchsia City. Have Drowzee evolve to Hypno and learn Psychic at Lvl. 35 to deal with Koga's team.

When Starting with Charmander

Pokemon FRLG - Charizard Charizard Pokemon FRLG - Kadabra Kadabra Pokemon FRLG - Hypno Hypno

If you started with Charmander, a Charizard is still strong against Koga with its high offensive stats, especially with Flamethrower in its moveset. If your Charizard is struggling to survive, then you can swap in a Psychic-type Pokemon like Kadabra or Hypno to deal super-effective damage.

When Starting with Squirtle

Pokemon FRLG - Blastoise Blastoise Pokemon FRLG - Kadabra Kadabra Pokemon FRLG - Hypno Hypno

If you started with Squirtle, Blastoise can also survive strong moves from Koga due to its defense stats. Blastoise can still deal decent damage with offensive Water-type moves, but it might not be enough to clear Koga's team alone. Have Blastoise team up with Kadabra and Hypno to cover Koga's weakness and clear out your opponent with ease by using Psychic.
