In hell dr.gero and myuu creates artifical 17. Artifical 17 comes from hell to fuse with android #17, when they fused, they became super17. Son Goku gets tricked into going to hell to fight cell and freeza, who was already dead. Without Son Goku, the earth is doomed.
Piccolo, (who died in the baby saga)and dende creates a portal so Son Goku can getout of hell Son Goku later he kills super 17. When the dragonballs are gathered to wish back the people killed in battle. But something goes wrong. shenlong says that all the negative energy the dragonball have retored, seven evil dragons have been formed. Each dragon possess a dragonball, so Son Goku and the z fighters go off to figth the evil dragons.
When they come up against li, ssj4 was shortened because of the 4th stage of super saiyan. They can only stay fused 20 min instead of 30 min. Just when gogeta was about to finish li, he diffuses. But the 2 warriors eventually killed the worn out li. When all seven dragons have been defeated, the real shenlong appears and grants Son Goku one wish is that everyone killed battle against the dragon to be brought back to life. Shenlong tells Son Goku to get on his back, then the seven dragonballs are absorbed into Son Goku, and his whole body vanishes,leaving only hisclothe on the ground. Seems that Son Goku is the most powerful fighter in the universe to have the dragonballs absorbed.
