Super saiyan

an advanced transformation assumed by extraordinarily powerful members of the Saiyan race!!!The ability to become a Super Saiyan was once considered to be nothing but a legend, because it had not been performed for over one-thousand years.The first Super Saiyan transformation occurs when a Saiyan who has reached a very high level of power, has a calm, pure heart (good or evil), and loses himself in a fit of rage. However, the transformation must be triggered in response to a great need, an example being in Goku's case to defeat Frieza. While physical change is not too drastic, the power output increase is colossal; the form is said to originally multiply the Saiyan's power by 50x times its normal amount, though it can be inferred that the power increase lessened somewhat, and the standard form became stronger, as new Super Saiyan levels were introduced.
