Force Rage, also known as Dark Rage, is a dark side ability. The user would tap into his or her innermost fears, pain and hate, converting them into intense anger. The user could then channel the anger to increase his or her own speed, strength, and ferocity. However, the body could not handle such rage for long periods of time, so the user became greatly weakened for some time after the rage subsided. If light side users wielded Force Rage, it could permanently disrupt their connection to the light side unless something happened to interrupt the Rage and bring them out of the dark side's grip. Therefore, the Rage could give the wielder an instantaneous physical and mental response, but pull them into deep depressions, physiological harm, and the endless void of the dark side.
