Overgrow (Ability)

Overgrow (Japanese: しんりょく Fresh Greenery) is an Ability introduced in Generation III. Twenty-one Pokémon can have this Ability, all of which are Grass types. All Grass-type starter Pokémon have this Ability.

Effect

In battle

Generations III to IV

When a Pokémon with Overgrow uses a Grass-type move, the move's power will be increased by 50% if the user has less than or equal to ⅓ of its maximum HP remaining.

Generations V onwards

Instead of boosting Grass-type moves' power, Overgrow now technically boosts the Pokémon's Attack or Special Attack by 50% during damage calculation if a Grass-type move is being used, resulting in effectively the same effect.

Outside of battle

Overgrow has no effect outside of battle.

Pokémon Mystery Dungeon series

In Pokémon Mystery Dungeon series, Overgrow will deal double the damage if the Pokémon using it is below 25% of its HP.

Pokémon Conquest

In Pokémon Conquest, Overgrow will increase user's Attack if the Pokémon using it is below ⅓ of its HP.
