Throughout your journey into the Sinnoh region, you’ll face 8 Gym Leaders and the Elite Four to finally challenge the Champion herself, Cynthia. Bertha is a member of the Elite Four in Pokémon Brilliant Diamond and Shining Pearl.
She’s the second Elite you’ll face after successfully defeating all 8 Gym Leaders to collect 8 badges. In this guide, we’ll be showing you how to defeat her. Bertha possesses a roster of extremely powerful Pokémon, making her one of the toughest opponents you’ll face in the game.
How to Defeat Bertha in Pokemon BDSP?
When facing Bertha in Pokemon BDSP, keep at least one Grass Type Pokémon with you, and the best one to do the job is Roserade.
Roserade is probably one of the most powerful Grass types in Pokemon BDSP with its high speed and who can forget its Giga Drain move? Have Roserade and Azelf in your team and you’ll win the fight in no time.
Since You’ll need Grass types later in the fight, let’s save Roserade for now and start with the one and only Legendary Psychic Azelf.
As the battle begins, Bertha sends out a level 55 Quagsire who drains 50% or more of your HP, followed by Whiscash, Sudowoodo, Golem, and Hippowdon.
Therefore, it’s best to fully use your X Defense from the Battle Items Pocket. However, if your Pokémon is wounded too much, use Hyper Potion instead to restore 120 HP of the Pokémon. To boost your Special Attack, use X Sp. Atk.
Once it’s your turn to attack, use Psychic to defeat all of Bertha’s Pokémon and proceed to the next Elite Four fight.
Bertha’s Pokemon
Every Pokémon in Bertha’s team is above level 50, meaning there’s a big difference between the level of your Pokémon and hers if you don’t grind enough by the time you defeat the Gym leaders.
You’ll have a rough time making it through the fight considering how dangerous Ground-type Pokémon are when it comes to ground attacks such as Earthquake. To ensure victory, train hard on Victory Road before tackling Bertha or any other Elite Four members.
