What type of villain do you want to see next?

How about somebody with a legitimate beef with Goku? Somebody whose family was perhaps wiped out by one of the many villains that have attacked Earth over the years and for some reason was unable to be wished back to life? Perhaps a guy whose planet was destroyed by Freeza on his way to Earth, which would have been spared had Goku had killed Freeza for certain on Namek? An astronaut whose spaceship was wiped out by a stray Kamehameha during Goku's training, perhaps.

Then again, we could get a whole Agrajag thing going. Some guy who keeps getting wished back to life but then dies from something Goku does, every time losing more of his sanity.

Id imagine any number of people would have some beef with Goku, especially after his fight with Fat Buu. He kicks Fat Buu into a skyscraper and brings the whole building down. How many people you think were in there?

Maybe someone makes a wish from the dragon that Goku was never born (if the dragon can do that)... then we have an alternate timeline where the villains succeeded and everyone has to somehow find a way to restore it.
