Fury

Fury is a status effect in Mario & Luigi: Bowser's Inside Story that can only be obtained by Bowser when he takes too much damage. When in this state, Bowser deals and receives more damage. The only way to cure this effect is to eat a Refreshing Herb or have a set amount of turns pass. While in the "Fury" status, Bowser's battle pose is different, he flashes red, and he shows more anger on his face.
