What happens is that Goku Jr. is walking in the park and finds a dragonball but with a gold star on it. He then find the others and bring them to Kamis Lookout and summons Shenlong the eternal dragon which is gold. Whats special about this dragon is that he can wish people back to life over 1000 times! Goku Jr. and Vegeta Jr. dont know what to wish for but Master Roshi whos up on the lookout (who as you know can live for ever because of a potion) has an idea. He suggests that Goku Jr. and Vegeta. Jr should wish for the whole Z crew back! They go with that plan and get summoned back once again to defend the earth.

A few months later Gohan is flying around with trunks and they spot chip lying on the ground. They return the chip to Bulma who inspects and tells them that theres something stored within the chip. Later that night Piccolo spots something coming out of Capsule Corp and follows it around until it realizes Piccolo is behind him. He turns around and introduces himself as Data..... the living organic robot! Data doesnt have a face. All he has is coding like you would see in the matrix. Just picture a matrix coded body, who can get the data and fighting skills of everyone. All he has to do is look into there eyes for 10 seconds. Your thinking why not just close your eyes right. Well if you try you can feel your self dying.
