Power Construct (Japanese: スワームチェンジ Swarm Change) is an Ability introduced in Generation VII. It is one of the signature Abilities of Zygarde.

Effect

In battle

At the end of a turn, if the HP of a Zygarde 10% Forme or 50% Forme with Power Construct is below half, it changes into Complete Forme.

Since Zygarde Complete Forme has a higher base HP stat, Zygarde's maximum HP will increase and its current HP will be revised to its new maximum HP minus the amount of HP it had lost before changing form. Additionally, its type becomes Dragon/Ground (if it had been changed by some effect).

At the end of the battle, Zygarde will change back to the Forme it started battle as, retaining the HP it had at the end of the battle. If this is above the maximum HP of its original Forme, its HP will become equal to its maximum HP.

Gastro Acid, Worry Seed, and Simple Beam fail if the target has the Ability Power Construct. Role Play, Skill Swap, Entrainment, and Doodle fail if either Pokémon has Power Construct. Power Construct cannot be copied by Trace, Power of Alchemy, or Receiver. Power Construct cannot be replaced by Mummy or Lingering Aroma, suppressed by Core Enforcer or Neutralizing Gas, or traded by Wandering Spirit. The increase in base HP is not considered healing, so it is not prevented by Heal Block. If a Pokémon other than Zygarde obtains Power Construct with Imposter or Transform, the Pokémon cannot change Formes.

Outside of battle

Zygarde with the Ability Power Construct cannot be separated back into Cores and Cells; however, the Zygarde Cube can be used to switch a Zygarde with this Ability between its 10% and 50% Formes.

In Generation VIII only, the Zygarde Cube can be used to switch Zygarde's Ability between Aura Break and Power Construct; in all games, Zygarde cannot switch Abilities through an Ability Capsule or an Ability Patch.
