Mega Drain is a Grass-type move with 40 power and 100% accuracy. It targets a single opponent and, upon hitting, it restores the user's HP by half of the damage dealt. Mega Drain is often used as a reliable recovery option early in the game, especially for Grass-type Pokémon. Although not as powerful as its successor, Giga Drain, it still provides a balance of moderate damage and healing, making it valuable for sustaining Pokémon in battles. Mega Drain can also be particularly effective against Water, Rock, and Ground types, leveraging its type advantage for both damage and healing benefits.
