Bug-Type Pokémon are a category of creatures in the Pokémon universe known for their small size and insect-like characteristics. They often have abilities that allow them to adapt to various environments, making them versatile in battles. Bug-types are typically weak against Fire, Flying, and Rock moves but are strong against Grass, Psychic, and Dark types. Many Bug-Type Pokémon evolve into stronger forms, gaining new abilities and characteristics. Some popular examples include Caterpie, which evolves into Metapod, and Scyther, known for its speed and agility. These Pokémon often play crucial roles in the ecosystem of the Pokémon world.
