Vegeta-Baby says himself he didn't acquire the strongest Saiyan power in history until after transforming from the power he absorbed. SSJ Vegetto would shit on him.
OG Atem would have mind-fucked everybody that got in his way at Duelist Kingdom, except maybe Kaiba. He could have gotten to the castle a lot quicker if he didn't have some honor to his name.
What the fuck? I never noticed that.
I'm actually surprised that didn't make it into the anime. There was less restriction at the start so it would have been fine.
I don't see what better feats he has in the S17 arc. Everything he accomplished in Super Saiyan was against a toying opponent. The next arc is hogwash for this.
