The Dragon Balls come from the distant planet Namek. The Namekians living there are born with an ability, which is to create seven Dragon Balls. When the seven Dragon Balls are put together and shouted "Shenlong", Shenlong will appear. It can fulfill a wish of the person who has collected all the Dragon Balls. No matter what the wish is, when the wish is fulfilled, the seven Dragon Balls will fly to all parts of the world and become ineffective for one year. After one year, they can be used again.
