Rompeaura (Aura Break)

Aura Break reverses the effects of the abilities Dark Aura and Fairy Aura while the Pokemon with this ability is on the field. Instead of boosting Dark-type or Fairy-type moves to 1.33x their power, these auras will reduce moves of their respective types to approximately 0.75x power.

This ability is passive and requires no activation — it automatically inverts any active aura the moment the Pokemon enters the field. If no Pokemon with Dark Aura or Fairy Aura is present, Aura Break has no effect. The ability does not affect any other abilities or field conditions.

Aura Break is the signature ability of Zygarde, the Order Pokemon introduced in Generation VI. It was specifically designed as a counter to Xerneas's Fairy Aura and Yveltal's Dark Aura, reflecting the lore of Zygarde as the balancing force in the Kalos legendary trio.
