The legend of the Super Saiyan tells of A super warrior of the Saiyan race who comes along once every thousand years (only one Super saiyan is supposed to be able to appear but I think 7 have. They messed this series up royally in several spots like this.) The levels of Super Saiyan go up to level 4. When they acheive this level (4) many different things happen(see list below).So anyway....this is a list of things you need to be (or do) to become a Super Saiyan!!
To be or not to be....Super Saiyan?!
