The Dark Super Saiyan was first used by Broly. This technique takes you to a new crazy level of a Super Saiyan. A Dark Super Saiyan has powers way past regular Super Saiyan, but unlike the regular there are some side effects. To begin to achieve this mode your heart must be black, soulless, unforgiving, and ruthless. The only thing you would ever want to achieve in this form is death and utter destruction. This attack also may alter your personality for good.
