Many centuries ago, a horrible catastrophe wiped out all the Namekians except Guru and a few Powered-Up Namekians who were exiled before. It is learned that the child of Katas, a gifted child of the Dragon Family, was sent off to Earth.

During the Namek Saga Planet Namek was terrorized by Frieza and his henchmen, Dodoria and Zarbon. The planet was ultimately destroyed by Frieza as a last-ditch effort to kill Goku in their battle during the Frieza Saga, as he was able to survive without oxygen in space.

All Namekians killed by Frieza and his henchmen (which did not include the deaths caused by Vegeta) were brought back to life and transported to Earth. The Namekians lived on Earth for nearly a year before being resettled on New Namek. It is unknown as to why the Dragon Balls were not used to restore the planet after it was destroyed instead.
