In addition to the three
New Legendary Pokemon and two
New Galarian Forms found in the
Isle of Armor Expansion Pass, there are also a total of seven brand
New Gigantamax Forms. Two of these
Gigantamax Forms belong to the Legendary Pokemon known as
Urshifu, one for each of its two different regular forms. Unlike the other Pokemon with
Gigantamax Forms, Urshifu can only obtain its Gigantamax Forms by way of a very special
Max Soup formula. Two more belong to Venusaur and Blastoise, completing the Kanto Starters Trio in terms of Gigantamax Forms. As you progress through the Isle of Armor Story, you will receive one of these two with their
Gigantamax Form as a
Gift Pokemon.
The final three brand
New Gigantamax Forms belong to each of
The Galar Region Starter Pokemon, including Rillaboom,
Cinderace, and
Inteleon. When it was first announced that these three would also be obtaining
Gigantamax Forms, it was believed that this would be done as a reward for only your
Starter Pokemon chosen at the beginning of the game. However, we now know that isn't the case.
Instead, Rillaboom,
Cinderace and
Inteleon each have a different method rather than
Max Raid Battles (like the other
Gigantamax Forms) to obtaining their
Gigantamax Forms.
In order to get Gigantamax Rillaboom, you must create and give it Max Soup with the help of Mega Mushrooms. Since Rillaboom earns its
Gigantamax Form via Max Soup, that means you can have any Rillaboom you have earn its Gigantamax Form. This is all the better as you can use the Max Soup on a Rillaboom with its Hidden Ability (which is the better of the two), rather than its Regular Ability like the
Starter Pokemon chosen at the beginning of the game is locked in on having. It's a win/win!
