In the world of Pokémon, each creature belongs to one or two specific categories known as types. There are 18 different types, including Fire, Water, Grass, and Electric. Each type has its own strengths and weaknesses against other types, which influences battles. For example, Water types are strong against Fire types but weak against Electric types. Understanding Pokémon types is essential for trainers to strategize during battles. When a Pokémon uses a move that matches its type, it deals extra damage, known as STAB (Same Type Attack Bonus). This system adds depth to gameplay, encouraging players to consider type matchups carefully.
