The dragon on earth is named Shenron and he can grant normally one wish. The balls turn into stones when used and are not usable for over a year, no one normally being able to tell if they are dragon balls. One time the dragon turned evil from granting so many wishes and seven evil dragons were let free from each dragon ball, thus wreaking havoc on earth, each having one element. Syn was one of the dragons being the most powerful dragon (which makes sense since he was the very first) and he fused with dragon balls becoming an entity and was destroyed by a spirit bomb absorbing almost all the energy within the entire galaxy including planet namek, planet earth, and other planets. The dragon on namek where the dragon balls originially existed. His name is Porunga and he can grant over two wishes. The dragon created from the climax of the fusion of piccolo and kami when they were still combined thus making these balls unstable and explodes the planet in a year. The name of the dragon is Shenron, but he's really different from the Earth Dragon. The dragon on earth is named Shenron and he can grant normally one wish.
