Defog is a Flying-type move with no power and 100% accuracy. It removes hazards such as Spikes, Stealth Rock, and Sticky Web from the battlefield and lowers the target's evasion by one stage. Defog does not deal any direct damage but is highly valued for its utility in clearing entry hazards, which can be crucial in both competitive and casual play. Additionally, it clears Light Screen, Reflect, Tailwind, Aurora Veil, and similar effects from the opposing team. It is often used by support Pokémon to maintain field control and hinder the opponent's strategy.
