Dragon Ball GT

Several years after the end of the Dragon Ball Z anime series.

Pilaf wants to use the Crystal Balls to dominate the world. He has discovered the existence of ancient Dragon Balls that have black stars instead of orange as ornaments! Together, they allow Pilaf to summon Shenron who is red in color. Pilaf misses his wish and Shenron changes Goku into a child. These evil Dragon Balls destroy, after one year, the planet where the wish was made. Goku has one year to reunite them and prevent the end of the Earth. He leaves with Trunks and Pan to search for the crystal balls scattered all over the galaxy.
They will meet a robot named Guigui, and a professor, Myû. This one creates Baby, a machine which protects him. Vegeta, Goten, Gohan and Oob are also present. Goku will develop a new form of super Saiyan when he has to fight an old "enemy".
