Super Strike (status effect)

Super Strike is a status effect in Mario & Luigi: Bowser's Inside Story that can only be obtained by Mario and Luigi via a badge effect that involves mixing the Powerful Badge with any of Luigi's badges. When in this state, the damage dealt by either Bro is multiplied to a certain amount (depending on the other badge in use) only on their next respective attacks. The status is indicated by stars moving upward, and Mario and Luigi may also strike a battle pose just before using a Special Attack.
