I really only count till the end of Frieza saga, everything else is bassicaly fanfiction with continunity..
In which case Superman would have to be clever, as Goku would be able to go ssj by the end of Dragonball Z and could mash him like potatoes. But if he can grapple him, hurl them both into space, and suffocate the monkey. Then Supes wins.
But that's giving Supes too much credit, Goku is not going to let his gaurd down so easily, could very well overpower Superman, and is going to give him hell. It would be a hard-time, but ultimately I believe Son Goku could win. It'd be alot like Doomsday versus Superman where he'd litteraly have to beat him to death. Exsept Earth would be ALOT more ruined then Doomsday would've left it.
I fear Mr. Satan is what Batman would've become had it not been for obsessive-compulsive, schizophrenic behaivor.. But then, as I said.. Mr. Satan was partof the "cotinuity fanfiction" era. Despite him being the only character with an actual personality besides a villain..
