How was planet Namek restored? Two months later, Vegeta having learned Forced Spirit Fission, liberates the stolen energy from Moro during battle with him and releases the energy back to its origin. As a result, the Namekians who had previously been killed after Moro sucked away their life energy are revived.
Where did the Namekians go? All of the Namekians were temporarily transported to Earth, where they lived for nearly a year before being resettled on New Namek. During the Cell Games Saga the young Namekian named Dende, is chosen by Goku to be Kami’s replacement as a new guardian of the Earth’s Dragon Balls on Earth.
Does Namek get destroyed? Frieza destroys Namek’s core, causing a countdown to the planet’s destruction.
Why didnt they wish Namek back? So Kuririn and Goku (or so they think) are dead, but they can’t be brought back to life because they’d appear on planet Namek – which is no longer there.
