Shenron (Shén Lóng. "God Dragon"), also known as the Eternal Dragon in the Ocean Group and Funimation dubs, Shenlong in the Viz manga, Shen Long in Japanese versions, and the Dragon God in the Harmony Gold dub, is the wish granting dragon summoned when all of Earth's Dragon Balls are gathered. Shenron can bestow any wish as long as it does not exceed the power of his creator (who must be still alive) and has not been previously granted. This is why Shenron can only bring the same person back to life once. Shenron can originally only grant one wish, but after being revived by Dende, he is able to grant two at a time. Shenron often tries to hasten summoners to make their wishes. He will usually threaten to leave or kill the summoner if they do not quickly make their wish, but never follows through with it.

His Namek counterpart is Porunga. Unlike Shenron, Porunga has a large, muscular upper body and various Namekian traits; he initially can only bring a single person back to life at a time, but can bring that person back multiple times. He can grant three wishes, so long as they don't exceed his creator's power, his creator is still alive, and each request is delivered in the Namekian dialect. Dragon Ball GT introduces the Black Star Shenron, a much larger red Shenron made by Kami when he and Piccolo Daimao were still one entity. He is summoned when the Black Star Dragon Balls are gathered, and can grant any single wish, regardless of any restrictions placed on the other dragons.
