Steel-type is one of the eighteen elemental types in the Pokémon universe. Pokémon with this type are known for their high defense and resistance to many attacks. They are typically strong against Ice, Rock, and Fairy types, making them effective in battles. However, they are weak against Fire, Fighting, and Ground types. In addition to their defensive capabilities, Steel-type Pokémon often have a metallic appearance and are associated with machinery and technology. Many Steel-type Pokémon, like Scizor and Metagross, are popular choices for trainers due to their versatility and strength in combat.
