Change his color? He's not black, he's an Indian.Ubb has the potential to become a main character, if...
-He undergoes a color changing surgery (like Michael Jackson)
-He collects Super Dragonballs and wishes to be genetically modified into a Saiyan
-He repeatedly hits his head with a hammer until he becomes less smart
-He legally changes his name to Goku
Goku did rescued him when the Earth was about to destroy.Nam's children mustve gotten married quick then
But then again thats to be expected from indian tribesmen
Be careful watch you wish for!I hope Super continues after EoZ so we can see how Toriyama would use Uub.
