Porunga
Porunga is a Namekian dragon who appears in the anime Dragon Ball GT. He is one of the two dragons that can grant wishes, the other being Shenron. Porunga is summoned by using the Dragon Balls, which are seven magical orbs that are scattered across the world. Once all seven Dragon Balls are gathered, they can be used to summon Porunga, who will then grant one wish.
Porunga is a powerful dragon, and his wishes are not limited by the same restrictions as Shenron's. For example, Porunga can grant wishes for immortality or the resurrection of the dead. However, Porunga's wishes do come with a price. Each wish costs one year of the summoner's life, and the more wishes that are made, the greater the price.
Porunga is a wise and benevolent dragon, and he always uses his power for good. He has helped Goku and his friends on many occasions, and he has always been willing to help those in need. Porunga is a powerful and important figure in the Dragon Ball universe, and he is sure to continue to play a role in future stories.
