Zygarde monitors the Pokémon ecosystem to ensure that it’s not disrupted. Zygarde believes it has a duty to protect the ecosystem. While the power it possesses is overwhelming, this Forme contains only 50% of Zygarde’s cells. Out in the world, an equal amount of power waits to be brought together.

A Zygarde 10% or Zygarde 50% with the Power Construct Ability will be able to change forms into its Complete Forme during battle if its HP drops below half.
