I think Goku mostly resembles Superman, if any of the western superheroes. Though, I don't know much about the latter, they are quite similar if you take out the fact that one fights with help and the other does not. Or maybe Gohan is more like Superman, as he did try to hide his superpowers and all. But he's more of like a what-if superman let his work weaken him sort of deal.
