Overgrow is an ability commonly found in Grass-type Pokémon and plays a strategic role in battles. Overgrow activates when a Pokémon's HP falls below one-third of its maximum. When triggered, it boosts the power of Grass-type moves by 50%, making them significantly stronger. This power-up can turn the tide of battle, allowing the Pokémon to deal considerable damage despite being in a weakened state.
Overgrow is one of the three standard abilities given to the starter Grass-type Pokémon in the Pokémon series, alongside Blaze for Fire-type starters and Torrent for Water-type starters. This thematic ability enhances their elemental moves during critical moments and encourages strategic planning and timing in battles.
Some notable Pokémon with the Overgrow ability include the Bulbasaur, Chikorita, Treecko, Turtwig, Snivy, Chespin, Rowlet, and Grookey evolutionary lines. The ability complements their already strong repertoire of Grass-type moves, offering them an edge as they endure damage during prolonged battles.
