Each Pokémon has six core stats: HP, Attack, Defense, Special Attack, Special Defense, and Speed. These determine their effectiveness in battle. Natures are a crucial element, as they boost one stat by 10% while lowering another by 10%. For example, an Adamant nature boosts Attack and lowers Special Attack. While not as complex as mainline games, understanding these basics can help you optimize your team. You can check a Pokémon's nature and stats in its summary screen.
