Within Pokemon Sword & Shield, almost every single Pokemon can Dynamax in battles that allows it. However, only 27 Pokemon have the ability to Gigantamax since these select Pokemon are the only ones with Gigantamax Forms. Gigantamax Forms don't differ all that much from Dynamax Pokemon, but they do give the Pokemon a change in appearance. Gigantamax Pokemon also receive special G-Max Moves that are exclusive to each of these given Pokemon.
For players looking to obtain Pokemon with the ability to have a Gigantamax Form, they will have to participate in plenty of Max Raid Battles. This is because players can only obtain these Gigantamax Forms by first capturing these Pokemon in their Gigantamax Form within a Max Riad Battle. This is true for Charizard, Butterfree, Machamp, Gengar, Kingler, Lapras, Snorlax, Garbordor, Melmetal, Corviknight, Orbeetle, Drednaw, Coalossal, Flapple, Appletun, Sandaconda, Toxtricity, Centiskorch, Hattene, Grimmsnarl, Alcremie, Copperajah and Duraludon.
Gigantamax Machamp, Gigantamax Coalossal and Gigantamax Flapple are exclusive to Pokemon Sword with Max Raid Battles; however, they can be shared from players in Pokemon Sword to those in Pokemon Shield. And so the same for Gigantamax Gengar, Gigantamax Lapras and Gigantamax Appletun being exclusive to Pokemon Shield. Some Gigantamax Pokemon - like Melmetal, Snorlax and Toxtricity - weren't available in Max Raid Battles at the release of Pokemon Sword & Shield; however, they will eventually come to Max Raid Battles through Wi-Fi Events.
Gigantamax Charizard can also be obtained by evolving the Gift Pokemon Charmander Leon will leave for you within his room to their family house in Postwick after completing the Main Story. Gigantamax Pikachu and Gigantamax Eevee can only be obtain by the family in the Meet Up Spot Station if you have Save Files for Let's Go Pikachu and Let's Go Eevee, respectively, on the same Nintendo Switch. Gigantamax Meowth can only be obtained during the initial Wi-Fi Event for it that corresponded with the release of the games. Eternamax Eternatus cannot be found or used outside of its capture battle.
