The Saiyajin's
The Saiyajin are a primitive race who lives only to fight. They originated from the Planet Plant which was renamed after their King "Vegeta". Over time their technology advanced after defeating the original inhabitants of the planet, the Tsufuru. The intergalactic tyrant, Freezer destroyed the Saiyajin race because he feared they were becoming too powerful. However, 6 Saiyajins survived, Kakarotto, Radditz, Vegeta, Nappa, Broly, and Taurus. Thus the Saiyajin race was able to continue its existence.
