Later on, it became "Goku is the only one that can do it", and he has to get stronger (which is largely unnoticeable), and at the end, he literally kicks the shit out of a god. Then they made Saiyuki Reload, and I can't see how it's even remotely watchable, since they completely changed that around and he looks like a pansy now.
