There was once an "Anger's Power" badge in the beta for Paper Mario. It would cause Mario to gain a dark red tinge of color, and pose angrily. Mario's turn would be controlled automatically in battles, while the partner is controlled by the player. Mario's attack would increase by 2, but is AI neglects common sense, such as jumping on top of spike enemies. The effect is very much similar to the common "Berserk" status of many RPGs.
