Your power explodes in a green aura as rage begins to fill your heart. You are a Legendary Super Saiyan, a being of incredible might. Your Super Saiyan forms are now five times as powerful (Super Saiyan 1 being a times-250 modifier instead of a times-50 modifier), and your power grows five times as fast with training.
However, you have trouble controlling this form, as you are filled with a berserker-like rage, and need to train to control it.
