How to get it
- Defeat Black Kyurem in raids when it is available.
- Selected event research may award the matching energy. It cannot be substituted with another Fusion Energy.
How to use it
- Have both eligible Pokémon available, open Kyurem, and select the matching fusion.
- The fused form persists until you separate it; separation returns the two Pokémon.
Worth knowing
For Freeze Shock, the Kyurem used in fusion must know Glaciate; the move changes with the fusion.
Separating is free, but fusing again costs energy and Candy again. Unlike Mega or Primal energy, Fusion Energy is not earned by ordinary buddy walking.
Choose the primary Pokémon before paying the fusion cost
Black Kyurem uses the primary Pokémon’s IVs. In this fusion that is Kyurem; a better appraisal on the partner Zekrom does not replace the primary Pokémon’s stats.
Power-ups applied while fused belong to Kyurem when the pair is separated. Do not budget as though one fused power-up develops both Pokémon.
Separation has no energy fee, but another fusion requires the fusion resources again. Two separate fusion operations therefore consume 2,000 energy in total, even if you reuse the same Pokémon. This differs from Crowned forms, which have their own rules for later changes.
