Mirror Armor

Mirror Armor is a Generation VIII exclusive ability that reflects any stat-lowering effects back to the Pokemon that caused them. When an opponent uses a move or ability that would lower the Mirror Armor user's stats, the drop is instead applied to the attacker while the user remains unaffected.

This reflection applies to both direct stat-lowering moves like Intimidate, Sticky Web, and moves with secondary stat-drop effects. However, Mirror Armor only bounces back the stat reduction itself -- it does not prevent the damage from an attacking move. For example, if hit by Snarl (which normally lowers Special Attack), the user takes damage but their Special Attack stays intact while the opponent's Special Attack drops instead.

Mirror Armor is the signature ability of Corviknight, the Steel/Flying type introduced in Sword and Shield. It makes Corviknight an exceptional Intimidate counter and a reliable defensive pivot in competitive play, as opponents cannot weaken it through stat manipulation without suffering the consequences themselves.
