>Goku is stong because he's directly inspired by Son Wukong and Journey to the West, and both it and DB are meant to protray the importance of finding ones self, and self improvement despite the circumstances of ones past.
And so wouldn't it be weird if out of nowhere Goku got oneshot by a beam comparable to one he tanked to the face when he was weaker just because the plot needs him to be out of the way for five minutes to facilitate two entirely different copouts?
