Moldbreaker is a Pokémon ability that allows the Pokémon with this ability to bypass the effects of the opponent's abilities that would otherwise prevent moves from affecting them. For example, it allows a Pokémon to hit opponents with abilities like Levitate, which normally grants immunity to Ground-type moves. This ability is particularly useful in competitive battles, as it provides strategic advantages against certain matchups. Moldbreaker emphasizes the importance of ability interactions in Pokémon battles.
