The Hydro Pump is a powerful water-based move used by various Pokémon in the Pokémon franchise. It is known for its high damage output and is typically associated with Water-type Pokémon. The move unleashes a strong jet of water, making it effective against Fire, Rock, and Ground-type opponents. In gameplay, Hydro Pump has a high base power but a lower accuracy compared to other water moves. This means it can deal significant damage when it hits, but there is a risk of missing the target. Trainers often use Hydro Pump strategically in battles to maximize its effectiveness.
