Mold Breaker is an Ability introduced in Generation IV.
Mold Breaker ignores the effects of Abilities that could potentially affect the damage or effects of a move that its user executes. For example, a Pokémon with Mold Breaker can hit opponents that possess Levitate by using Earthquake. Mold Breaker applies regardless of target Pokémon, but only to moves executed by its user (so if two Pokémon in a Double Battle both know Earthquake, only the Pokémon with Mold Breaker can hit a Pokémon with Levitate).
Unlike Gastro Acid, which completely negates a target's Ability, the opponents' Abilities otherwise remain in effect:
- Abilities that prevent status conditions (such as Immunity and Oblivious) will not protect the Pokémon from receiving the status condition; however, many of these Abilities also have effects to cure the Pokémon of the status condition if afflicted, which are not negated by Mold Breaker.
- Abilities that draw attacks to the user, such as Lightning Rod and Storm Drain, will still divert attacks regardless of Mold Breaker, but will not nullify the damage or boost the Pokémon's stats.
- If a Pokémon with Own Tempo consumes a held Berry that may cause confusion in response to the move of a Pokémon with Mold Breaker, it will become confused if it dislikes the flavor (although Own Tempo will then activate and cure it of confusion).
Mold Breaker can ignore the Abilities of Pokémon other than the target; for example, if a Pokémon with Mold Breaker uses Thunder Wave on a Grass-type Pokémon whose ally has Flower Veil, the target will still be paralyzed.
Outside of battle
Mold Breaker has no effect outside of battle.
