Aura Break reverses the effects of the abilities Fairy Aura and Dark Aura, reducing the power of Dark-type and Fairy-type moves by 25% for all Pokémon on the field, instead of boosting them.
Aura Break is unaffected by Mold Breaker, Teravolt, or Turboblaze.
This ability is the signature ability of Zygarde, while the abilities it reverses—Fairy Aura and Dark Aura—are the signature abilities of Xerneas and Yveltal, the legendary Pokémon from Pokémon X & Y.
