Pokémon Scarlet & Violet: How to Defeat Arven

Before players can explore the depths of the Great Crater of Paldea in Pokémon Scarlet & Violet, they will need to defeat Arven in battle. Although the Professor's son acted as a partner when battling against the Titans of the Paldea region, he challenges players to a battle of their own to determine whether they are ready to take on the powerful Pokémon that await them in the Great Crater. With his fully recovered partner, Mabosstiff, Arven is up to the test. To defeat his diverse team, trainers must apply the battling skills they've acquired on their journey through the Paldea region.
