Shenron

Shenron is the eternal dragon god. The Nameks made these 7 mystical orbs called dragonballs for which they can gather and summon Shenron. When all 7 dragonballs are gathered and the user calls on the dragon, Shenron appears and grants a wish. In Dragonball, Shenron appears when the Earth's Dragonballs are used. These Dragonballs were made by Kami after he came to Earth. On Namek, Master Guru made the Dragonballs and a dragon named Porunga appears.
