Strategies to Overcome Bertha (Elite Four) in Pokémon BDSP

As you embark on your adventure through the Sinnoh region, you’ll encounter 8 Gym Leaders before finally facing the Champion herself, Cynthia. Bertha serves as a member of the Elite Four in Pokémon Brilliant Diamond and Shining Pearl.

She is the second Elite you will confront after defeating all eight Gym Leaders to earn your badges. In this guide, we’ll provide you with strategies to take her down. Bertha’s Pokémon lineup is incredibly formidable, making her one of the most challenging foes in the game.

How to Defeat Bertha in Pokémon BDSP?

When battling Bertha in Pokemon BDSP, ensure you have at least one Grass-type Pokémon in your party, with Roserade standing out as the top choice.

Roserade is one of the strongest Grass-types available in Pokémon BDSP, boasting high speed and a powerful Giga Drain move. Pair Roserade with Azelf on your team, and victory will be within reach.

Since you’ll need Grass-types later on, it’s wise to hold off on using Roserade initially and start with the Legendary Psychic type, Azelf.

At the start of the battle, Bertha will send out a level 55 Quagsire, which can deal significant damage to your HP, followed by Whiscash, Sudowoodo, Golem, and Hippowdon.

It’s advisable to maximize your X Defense from the Battle Items pocket. However, if your Pokémon takes substantial damage, don’t hesitate to use a Hyper Potion to restore 120 HP. To enhance your Special Attack, utilize X Sp. Atk.

When it’s your turn, launch a Psychic attack to eliminate Bertha’s Pokémon and advance to your next Elite Four challenge.
