Gigantaxmaxing is a new Pokémon Sword and Shield feature. While every Galarian Pokémon can Dynamax, only a few of them can Gigantamax. Pokémon that are capable of Gignatamaxing are pretty rare, but there are a few ways you can improve your chances of getting them.
Come ottenere Pokémon Gigantamax in Sword and Shield
Taking part in Max Raid Battles is an excellent way to get Gigantamax capable Pokémon. Max Raid battles involve a team of Trainers facing a very powerful Pokemon. You can join them as soon as you arrive in the Wild Area, but they are very difficult at that stage of the game. Look for glowing red rock formations with a beam of light coming from them to join a Max Raid battle. While it is possible to take part in these battles with AI teammates if you are offline, it is definitely worth being online to play them.
Nintendo will organize special events in the game that increase the chances of finding certain Pokémon during Raid Max battles. From November 15th, all players will have a better chance of encountering Gigantamax Butterfree. People with Sword will have a higher chance of encountering Gigantamax Dreadnaw, while people playing Shield will have a high chance of encountering Gigantamax Corviknight.
Game Freak has strongly suggested that these increased possibilities will pass to several Pokémon in the next couple of months. There are also methods that allow you to get Gigantamax Meowth, Eevee and Pikachu under special conditions. Meowth is available as an early purchase bonus, while Eevee and Pikachu are only available to people with a relevant Let's Go save file on their Switch.
