Dragon Balls
Dragon Balls is a comic book object that first appeared in DragonBall #1
The 7 magic Dragon Balls, when gathered, are able to summon a mystic dragon capable of granting wishes
Origin
The Dragon Balls, numbered 1 through 7, when collectively gathered, can be used to summon the eternal dragon who can grant wishes to the summoner. The Dragon Balls were originally created by the Namekians.
Earth
The Earth Dragon Balls were made by the Namekian, Kami, when he traveled to the planet Earth. Once used, they are turned into stone, and cannot be used unless revived by Kami, or another Namekian for one year. Once used, the dragon balls disperse across the planet and must be found again.
The Earth dragon balls summon the eternal dragon Shenron. He can grant one wish. When he was revived by Dende, he could grant two. He can only revive a person from death once.
The first Dragon Ball introduced was the "4 Star" ball. It was carried by Goku through much of the original Dragon Ball series. It was said that the "4 Star" ball held the spirit of Grampa Gohan, his adoptive Grandfather. These Dragon Balls could be found using the Dragon Radar, an invention made by Bulma Briefs, of Capsule Corp.
Namek
There are also seven dragon balls on the planet Namek, home of their origin. They are much larger than the Earth dragon balls. They summon the eternal dragon Porunga, who is capable of granting three wishes and has no limitations on reviving the dead.
After Namek's destruction, the Namekian dragon balls followed the Namekians to their new home.
