After five years, Niantic has finally introduced form changing in Pokémon Go. Although this mechanic is currently limited to only a handful of Pokémon, before we know it, Pokémon with multiple forms, like Hoopa and Castform may be able to swap between their different forms. However, changing form in Pokémon Go doesn't work as easily as it does in the core games. Fortunately, we here at iMore know everything there is to know about form changing in Pokémon Go, and be sure to check out our best Pokémon Go accessories so you can be fully equipped on your Pokémon Journey!
What are forms in Pokémon Go?
Beginning with Gen II and Unown, some Pokémon have been introduced with multiple variants or forms. Sometimes these forms differ only in aesthetics, while other form changes provide boosted stats, type changes, and more. While some Pokémon with multiple forms cannot change forms, most can swap between their various forms in the core games using items, special moves, the weather, and other in game mechanics.
There are many Pokémon with multiple forms now, including several that have already been introduced in Pokémon Go; however, prior to the Season of Mischief, form changing wasn't possible. Instead, Pokémon with multiple forms were treated as almost completely separate species. Take Castform for example: Castform has different forms depending on the weather. When Castform made its way into Pokémon Go, each weather version was its own Pokémon, only sharing Candy.
That's all changed with the Season of Mischief. First, with the introduction of Furfrou in the Fashion Week event and then with Hoopa, select Pokémon can now change forms.
Form or forme: what's the difference?
As some players may have noticed, occasionally a Pokémon's multiple forms will be refered to as "formes". While this term is usually researved to differentiate the purely cosmetic form changes from those with substantial differences, it has never been consistently applied, leaving many players confused as to which term applies to which species. To avoid confusion, this guide will stick with "form".
Costumes, Mega Evolution, and more
In the core games, Costumed Pokémon, Mega Evolved Pokémon, including the Primal Reversions of Groudon and Kyogre, and Regional Variants are all considered separate forms. These Pokémon will not be included in this guide. You can check out our guides on Mega Evolution and Regional Variants to learn more.
How to change forms in Pokémon Go
Currently, there are only two Pokémon who can change forms in Pokémon Go, but it's only a matter of time before more are introduced. Changing forms in Pokémon Go currently costs Candy and Stardust, and can have other limitations as well.
The first Pokémon given the ability to change form in Pokémon Go is Furfrou. This Normal type Pokémon has ten different forms, but the differences are purely aesthetic. In the core games, the different forms were obtained by grooming Furfrou at different Pokémon Stylists for 500 Pokémon dollars and the change would last for up to five days or until the Furfrou was deposited in the PC, Pokémon Bank, or the daycare/nursery.
In Pokémon Go, Furfrou requires 25 Furfrou Candy and 10,000 Stardust to change forms and will retain its form permanently so long as it isn't transferred to the core games. Additionally, some of its forms are currently region locked:
- Natural Trim: Caught in the wild
- Matron Trim: Available globally
- Dandy Trim: Available globally
- Debutante Trim: Available in the Americas
- Diamond Trim: Available in Europe, the Middle East, and Africa
- Star Trim: Available in the Asia-Pacific region
- La Reine Trim: Available in France
- Kabuki Trim: Available in Japan
- Pharaoh Trim: Available in Egypt
- Heart Trim: Available during the Valentine's Day event only
The second Pokémon given the ability to change form in Pokémon Go is the Mythical Pokémon Hoopa. Hoopa can currently only be caught in its Bound form by completing the Special Research, Misunderstood Mischief. Players who have completed Misunderstood Mischief by the end of the Season of Mischief can then complete a second Special Research, Mischief Unbound to unlock the ability to change Hoopa's form.
- Changing from Hoopa Confined to Hoopa Unbound requires 50 Hoopa Candy and 10,000 Stardust
- Changing from Hoopa Unbound to Hoopa Confined requires ten Hoopa Candy and 2,000 Stardust
Players who are unable to complete Misunderstood Mischief in time can purchase Mischief Unbound for $4.99USD or local equivalent in the PokéShop. However, players will still need to progress far enough in Misunderstood Mischief to catch Hoopa.
