This is a 2.0 version of the shadow dragons saga in gt.It will have 14 evil dragons instead of just 7. Vegeta has just summoned the dragon and wishes to be stronger than Goku.Shenron says "I can't grant that wish.In order for that wish to be granted you would have to go to Namek and use their dragonballs and the Earth's ones at the same time.But l suggest you achive your goal by training instead.For if me and Porunga meet it will create 14 evil very strong dragons that will kill you and destroy Namek.You'll only get your wish if you defeat every last dragon."Shenron then goes back into the Dragonballs.But they don't go around the world to be hidden for a year because no wish was granted.
