A Max Move (Japanese: ダイマックスわざDaimax Move) is a special type of move introduced in Generation VIII. While Dynamaxed, all of a Dynamax Pokémon's moves are replaced by their corresponding Max Moves. Max Moves are more powerful than regular moves.
The Max Moves that a Dynamax Pokémon knows depend on the moves its knew before Dynamaxing. The Max Move that a damaging move becomes depends on its type; status moves instead all become Max Guard. For Gigantamax Pokémon, damaging moves of a certain type become its exclusive G-Max Move instead of the normal corresponding Max Move; the type of moves affected depends on the Gigantamax Pokémon's species.
