First of all, Dragon Ball Dragon Ball is a four-claw dragon, because dragons in Japan and South Korea are both three-claw dragons and four-claw dragons. In China, three-claw dragons and four-claw dragons are pythons, and five-claw dragons are dragons.
In ancient China, the kings of princes and counties wore embroidered robes, which were equivalent to the emperor's brothers, and the five-claw golden dragon was the emperor's patent. As for the reason why Japan and South Korea can't use five-claw dragon, after all, ancient China is called the kingdom of heaven, and other countries are not allowed to use five-claw dragon.
Final outcome
At the end of Dragon Ball GT, after the dragon was destroyed, the dragon suddenly appeared without being summoned (the sky was not dark at this time), and told people that the dragon ball could not be used by them any more, and he would never appear again. Then the dragon said to the Monkey King, "Wukong, come up."
The Monkey King replied, "Ah, is it time already?" Then the Monkey King rode away on a dragonfly and merged with the seven dragon balls. No one has seen the Monkey King and Dragon since then.
