Flash is a Normal-type move with no power and 100% accuracy. It lowers the target's accuracy by one stage, making it harder for the opponent's moves to hit. Flash is often used strategically to create openings for other moves by reducing the target's likelihood of landing attacks. In addition to its in-battle effects, Flash is frequently used outside of battle in various Pokémon games to illuminate dark caves and tunnels, making it an essential move for exploration in certain regions.
