Goku Blue: Super Butoden Xenoverse Tenkaichi

This is an advanced transformation assumed by extraordinarily powerful members and hybrids of the Saiyan race in Goku Budokai

The ability to become a Super Saiyan was once considered to be nothing but a legend, as it had not been performed for over one-thousand years. Vegeta stated that a Super Saiyan has achieved a level of power so overwhelming that it could only be maintained in a transformed state. Despite only being told through legend, Frieza, who has Saiyans in his army, became paranoid over the possibility of truth behind the legend due to the constantly growing power of the Saiyan race.

Because of this fear, Frieza came to the conclusion that he must annihilate the Saiyan race by destroying Planet Vegeta, thus apparently sparking the end of the Super Saiyan legend. However, twenty-five years later, the Super Saiya legend was proven to be true when Goku accomplished the feat during his titanic battle against the evil tyrant, Frieza.
