Fusion is a process that certain Pokémon can undergo to change form by combining with certain other Pokémon. After undergoing Fusion, the new form of the Pokémon will feature a change to their appearance, improved battle performance through changed states, as well as other benefits.

Pokémon that are eligible to undergo Fusion will have a “Fuse” button and “Fusion Energy” on their summary page.

How do my Pokémon undergo Fusion?

In order to undergo Fusion, you will need sufficient Candy for both Pokémon. You will also need to generate enough Fusion Energy for that Pokémon. Fusion Energy is generated in a number of ways including Special Research and as rewards in Fusion Raids. 

It’s important to note that different types of Fusion Energy are required for a Pokémon to undergo Fusion with specific Pokémon. For example, for Necrozma to undergo Fusion with Solegao it requires Solar Fusion Energy, however Lunar Fusion Energy is required to undergo Fusion with Lunala.

How do I Fuse my Pokémon?

Once you have collected enough Candy and Fusion Energy go to an eligible Pokémon’s summary page and tap “Fuse” next to the Pokémon you’d like to Fuse with. You’ll then be able to pick which individual Pokémon of that Pokémon species you’d like to Fuse with. Tap Yes to begin Fusion.

   

After undergoing Fusion, your Pokémon will stay in this new, fused form indefinitely. To Separate your Pokémon, locate the fused Pokémon in your Pokémon inventory and open its summary page. In place of the “Fuse” button will be an option to Separate your Pokémon. There is no Candy or Fusion Energy cost to separate your Pokémon.

Note that multiple Pokémon can undergo Fusion at the same time, unlike with Mega Evolution or Primal Reversion, as long as you have enough eligible Pokémon in your inventory.

Once your Pokémon have Fused, it will have improved Combat Power. This will make your Fused Pokémon more effective when brought into Raid Battles, Gym Battles, Team GO Rocket Battles, etc. Additionally, certain Fused Pokémon will gain a special Charge Attack.

Fusion Raids

Fusion Raids are similar to standard Raid Battles. However, the Pokémon you are challenging is more powerful than you may have previously experienced. To improve your chances of defeating the Fusion Raid, try Mega Evolving a Pokémon in your Raid Party, inviting Friends to join you in the Fusion Raid, or both! Note that, after defeating the Fused Pokémon in the Fusion Raid, you will only be able to encounter and capture the base Pokémon.
