Grass-type is one of the elemental types in the Pokémon series, known for its connection to nature and plant life. Pokémon of this type often have abilities related to healing, growth, and environmental interactions. They are typically strong against Water, Ground, and Rock types, making them effective in battles against these elements. However, Grass-type Pokémon are weak against Fire, Flying, Bug, Ice, and Poison types. This means they can struggle in battles against these opponents. Many Grass-type Pokémon also have moves that can inflict status effects, such as sleep or paralysis, adding strategic depth to their use in combat.
