Water Gun is a Water-type move with 40 power and 100% accuracy. It is one of the most basic Water-type moves, often available to many Water-type Pokémon at lower levels. Water Gun's reliability comes from its perfect accuracy and decent power for early-game battles. It is especially useful for weakening opponents without the risk of missing. As trainers progress, they often replace Water Gun with stronger Water-type moves, but it remains a staple for beginners due to its simplicity and effectiveness.
