Gigantamax Pokémon The previously discovered phenomenon known as Dynamaxing can only occur in specific areas of the Galar region. While Dynamaxing seems to be a phenomenon common to Pokémon from Galar, it’s been discovered that there’s a special phenomenon known as Gigantamaxing. Not only do Gigantamax Pokémon become bigger, but their appearance also changes. Like normal Dynamaxing, Gigantamaxing boosts the power of the Pokémon—and it also allows each Gigantamax Pokémon to use a unique move known as a G-Max Move. Each G-Max Move is particular to a specific species of Gigantamax Pokémon, and regular Dynamax Pokémon are not able to use G-Max Moves. Only certain species of Pokémon can Gigantamax—and even among such species, only rare specimens will be able to Gigantamax.
